A method for increasing mechanical strength of a dielectric film includes: providing an initial dielectric film containing porogen; irradiating the initial dielectric film with first UV light having a first wavelength which is substantially or nearly similar to a maximum light absorption wavelength of the porogen for removing the porogen; and then irradiating the porogen-removed dielectric film with second UV light having a second wavelength which is shorter than the first wavelength, thereby increasing mechanical strength of the dielectric film.

A refrigeration cycle apparatus includes a compressor, a radiator, an expander, an evaporator, a bypass circuit, and an injection circuit. The bypass circuit has a flow rate control valve and a gas-liquid separator. One end of the bypass circuit is connected to an intake conduit of the expander and the other end thereof is connected to a discharge conduit of the expander so that a portion of refrigerant passed through the radiator bypasses the expander and is guided to the flow rate control valve and that the liquid refrigerant separated by the gas-liquid separator returns to the discharge conduit of the expander. One end of the injection circuit is connected to a gas outlet portion of the gas-liquid separator and the other end thereof is connected to an intermediate pressure portion of the compressor.

The test turntable comprises a turntable part, a sensor part, an electric conduction slip ring part, a clutch and brake device part, and a motor and bevel gear transmission case part; the motor and bevel gear transmission case part is fixed into a foundation through screws; the clutch and brake device part is fixed on the foundation through screws; the clutch and brake device part is connected with the motor and bevel gear transmission case part through a coupler; the electric conduction slip ring part is fixed on the clutch and brake device part through screws through screws and is adjusted horizontally through an adjusting shim; the sensor part is connected with the electric conduction slip ring part through screws and is horizontally adjusted through the adjusting shim; and the turntable part is connected with the sensor part through the screws and is horizontally adjusted through the adjusting shim.

A fuel injection system for internal combustion engines includes an injector supplied from a high-pressure fuel source and with a pressure booster device, in which the closing piston can be acted upon by fuel pressure to attain a force exerted on the closing piston in the closing direction, and in which the closing pressure chamber and the return chamber of the pressure booster device are formed by a common closing pressure return chamber, and all the portions of the closing pressure return chamber communicate with one another permanently for exchanging fuel, so that despite a low pressure boost by the pressure booster device, a relatively low injection opening pressure is attainable.

A digital phase locked loop includes a digital phase detector, a downstream digital filter and an oscillator. In addition, a frequency divider resides in a feedback path and has an actuating input for setting a divider ratio, the input of which is connected to the oscillator and the phase detector. The phase locked loop comprises a sigma-delta modulator having a data input for supplying a data word and having an actuating output for supplying a frequency setting word to the actuating input of the frequency divider. The data word is configured such that the sigma-delta modulator generates jitter in the frequency setting word, with the result that the signal which is applied to the feedback input of the phase detector is not constant over a relatively long period of time.

An infrared induction based non-contact novel dustbin comprises a barrel cover; a control chip is arranged in the barrel cover; an infrared inductor and a distance induction sensor are arranged outside the barrel cover; a dynamo electric gear is arranged in a connecting portion between the barrel cover and the barrel body; the top of the barrel cover is provided with a solar panel; when people throw garbage to the dustbin, the dustbin can sense hand approaching, and the built in control system can automatically open the barrel cover; when the people is sensed to leave, the barrel cover can be automatically closed; in addition, the garbage level in the barrel can be detected so as to obtain present garbage volume, and different colors of an indication lamp on the barrel cover can display different volumes; when the dustbin is full, a prompt voice can be given so as to remind people to timely clean; the novel dustbin is intelligent, environmental protective, and energy saving.

A computer system has one or more program classes loaded in it. Each class includes a constant pool which is used for storing data items related to the program class. At least some of these data items need to undergo a resolution before they can be used, which transforms them from their initially loaded value into a usable value. In accordance with the invention, the system maintains both the unresolved value and the resolved value in the constant pool entry for a resolved data item. This allows the resolution process to be performed without using locks, thereby avoiding potential system delays due to contention for locks.

A surround sound audio processing system includes a source that supplies a first signal for producing a first sound impression and a second signal for producing a second sound impression. A processing unit modifies the first signal and the second signal to produce a third sound impression of a virtual source, and provides first and second modified signals indicative thereof. The processing unit modifies the first signal and the second signal relative to each other such that the first and second modified signals have a phase shift of between 170° to 190°.

The invention relates to a tongue depressor for department of pediatrics. The tongue depressor comprises a lower bracket, an upper bracket, connecting plates, an upper denture assembly, a lower denture assembly, a tongue depressing plate, an upper sliding seat, an upper fixed seat, a lower sliding seat and a lower fixed seat, wherein the upper bracket can be arranged on the lower bracket in an up-and-down sliding manner; the upper fixed seat is arranged on the upper bracket; the upper sliding seat is arranged on the upper bracket; the lower fixed seat is arranged on the lower bracket; the lower sliding seat is arranged on the lower bracket; the connecting plates are arranged between the upper sliding seat and the lower fixed seat, as well as between the upper fixed seat and the lower sliding seat; the upper denture assembly is arranged on the upper bracket; the lower denture assembly is arranged on the lower bracket; a rotating seat is arranged on the lower denture assembly; and the tongue depressing plate is arranged in the rotating seat. Through the adoption of the tongue depressor for department of pediatrics disclosed by the invention, teeth of a sick child can be convenientlypushed open to an appropriate position and positioned, the situation that during inspection, the sick child voluntarily closes mouth and teeth, and the inspection is inconvenient is avoided.

An image memory access control unit (502) judges whether or not an additional pixel required for motion compensation is necessary, the additional pixel not being included in a plurality of pixels forming an image shown by a reference block. When the additional pixel is judged to be necessary, a yet-to-be-obtained-pixel interpolating unit (503) generates at least one additional pixel, and generates a reference image to be used for motion compensation using the generated at least one additional pixel and at least a part of the image shown by the reference block. When the additional pixel is judged to be unnecessary, the yet-to-be-obtained-pixel interpolating unit (503) outputs at least a part of the image shown by the reference block as the reference image.

Provided are hypromellose acetate succinates (HPMCAS) for use as a hot-melt extrusion carrier having a volume average particle size (D₅₀) of from 70 to 300 as measured by dry laser diffraction and a loose bulk density of from 0.25 to 0.40 g/cm³; and a hot-melt extrusion composition comprising the HPMCAS and a drug. Also provided is a method for producing a hot-melt extrudate including the steps of: hot-melting the hot-melt extrusion composition at a hot-melt temperature equal to or higher than a melting temperature of the HPMCAS, or at a hot-melt temperature equal to or higher than a temperature at which both of the HPMCAS and the drug become melt; and extruding the hot-melted composition.
