A dummy hair clipper head which conforms to those dimensions of the head of a hair clipper (its stationary blade) which are necessary for its compatibility with attachment guide combs. This dummy hair clipper head provides a base onto which the attachment guide combs can be attached, and by which they can be held, allowing them to be organized within a kit among other uses. The dummy hair clipper head can be connected to a tool to allow the combs to be used with that tool, such as a pair of scissors to create a scissor comb, or including a conduit through the dummy hair clipper head to be used as a vacuum comb, a dryer comb, and a liquid dispensing comb.

A roman shade comprises an operation box section for rotating a rotation gear as a driving ball chain (25) is pulled down; a rotation shaft (40) fitted into the rotation gear; a frame surrounding the operation box and the rotation shaft (40) and secured to a wall or ceiling; and a ball chain box section including an inside gear which is fitted around the rotation shaft (40), a driven ball chain (22) which has balls to be engaged into grooves defined on the inside gear so that the driven ball chain (22) is moved vertically as the inside gear is rotated, and a ball chain box in which the driven ball chain (22) is compiled without being entangled.

A solid-state image sensor has a readout architecture that incorporates charge multiplier cells into a horizontal register of a CCD image sensor, and includes a first CCD register adjacent to at least a second CCD register and coupled to the said first register through a charge overflow barrier. A high Dynamic Range readout system results in which the DR is not restricted by the voltage swing limitations on the charge detection node. As the charge is multiplied, the horizontal register structure increases in width and more charge multiplication gates are added per stage. A charge overflow region follows the charge multiplier. In this region the amount of charge that exceeds a certain predetermined threshold is split off into another register. A detection node that has different conversion sensitivity may terminate this register. The process of charge overflow and splitting off may continue for more than two steps.

A high voltage and high power boost converter is disclosed. The boost converter includes a boost converter IC and a discrete Schottky diode, both of which are co-packaged on a standard single common die pad.

An operational amplifier having a wide input common mode voltage range includes first (2) and second (3) differential input transistor pairs coupled to first (14) and second (15) tail current transistors. At least one of the first and second tail current transistor pairs is controlled by a common mode control circuit (4). A gate of the first tail current transistor (14) is coupled to the common mode control circuit (4) to turn the first tail current transistor on and to turn the second tail current transistor off when the common mode input voltage is below a common mode threshold voltage (CMTHR). A folded cascode stage (5) is driven by the first and second differential input transistor pairs. Switched active load transistors are coupled to active load transistors of the folded cascode stage and are operable in response to the common mode control circuit to divert part of a current produced by one of the first and second differential input pairs from the folded cascode circuit, depending on whether the common mode input voltage is above or below the common mode threshold voltage.

The present invention provides a bodily fluid-testing composition for the determination and quantification of a specific ion concentration exceeding a pre-set threshold in a tested fluid, in which an ion oppositely charged to the ion in the bodily fluid is used to compete with an indicator reagent in order to compensate for variability in specific binding of the bodily fluid ions. The present invention further provides an article for monitoring of bodily fluids comprising a substrate and an absorbent material for absorbing the bodily fluid. The substrate includes a composition suitable for identification of a specific ion concentration in a tested fluid. The article can be used to indicate the presence of abnormal ammonium concentration in human urine, amniotic fluid leakage, or biogenic secretions associated with bacterial vaginosis, parasite infections, or deficiency of lactobacillus population, without giving a false positive result.

In a bipolar transistor including a base layer made of SiGe, a non-did SiGe layer and a non-doped Si layer are provided between the base layer and an emitter layer. The composition ratio of Ge in the emitter side of SiGe base layer is decreased with increasing proximity to the emitter side, and the composition ratio of Ge in the non-doped SiGe layer is a smaller than the composition ratio of Ge at the emitter layer-side end of the SiGe base layer. In this manner, restriction is put on the diffusion of boron from the base layer to the emitter side, and the base-emitter junction capacitance CBE reduced. Furthermore, the direct-current gain beta can be improved by increasing the composition of Ge at the emitter end of the SiGe base layer to more than or equal to a predetermined value.

A reversible seat cup allows free floating or fixed positioning of the seat cup, depending on application. For applications where the cymbal needs to be rigidly held, such as China cymbals, and / or minimal stand noise is essential, such as symphonic performances or studio applications, the seat cup can be positioned with the convex side positioned downward and “locked” firmly to the threaded post. A rubber O-ring on the threaded post fits into a receptacle in the seat cup to provide secure attachment and silent action. For applications where the cymbal, such as crash cymbals, needs freedom of movement, the seat cup can be positioned with the convex side positioned upward. A cavity on the opposite side allows the seat cup to float on the rubber O-ring for optimal cymbal sound. The plastic-type material of the seat cup and the rubber O-ring provides silent action and freedom of motion.

A ballast for an electrodeless discharge lamp includes a high frequency power supply that supplies a high frequency electric power to an induction coil for operating the lamp. A dimmer controller generates a control signal in response to a dimmer command designating a varying dimming ratio. The control signal defines a first period Ton in which the power supply is controlled to apply a coil voltage of a first level V1 to the induction coil for operating the lamp. The first period is followed by a second period Toff in which the power supply is controlled to apply the coil voltage of a second level V2 that is lower than the first level and fails to sustain the lamp. The control signal defines, between the second period and the first period, a starting period Tst in which the coil voltage increases continuously for smooth transition from an off-condition to an on-condition of the lamp.
