Device and method for detecting disc defect

A method for detecting a typical defect area on a disc track includes the following steps. Firstly, a source signal is provided. Then, first and second signals are generated according to the source signal. The first and second signals are held at the peak level of the source signal and respectively decreased at first and second drop rates. Then, first and second threshold values are subtracted from the first and second signals to generate first and second slice signals, respectively. Afterwards, the source signal is compared with either the first slice signal or the second slice signal. When the first slice signal is larger than the source signal, a typical defect signal is changed from a first level to a second level. Whereas, the typical defect signal is changed from the second level to the first level when the second slice signal is smaller than the source signal.

Four-direction switch device

A four-direction switch device is used for facilitating the user to operate an electronic apparatus in four directions. The four-direction switch device includes a three-direction switch element, a swing module and a unidirectional switch element. The three-direction switch element is triggered to generate a first direction switching signal, a second direction switching signal and a third direction switching signal. The swing module includes a swing shaft such that the swing module is swung with respect to the swing shaft. The unidirectional switch element is triggered to generate a fourth direction switching signal when the swing module is swung to touch the unidirectional switch element.

Disclosed are an ultrahigh-pressure sodium hypochlorite generator and a preparation method of sodium chlorate. The ultrahigh-pressure sodium hypochlorite generator comprises a shell with a water inletand a water outlet, a plurality of cathode pressing plates and a plurality of anode plates which are sequentially stacked at intervals are arranged in the shell, and the cathode pressing plates and the anode plates are provided with center holes. A center shaft penetrates through the center holes to position and press the cathode pressing plates and the anode plates to form a disc type structureand block the cathode pressing plates and the anode plates at the positions of the center holes. Strong brine enters from the water inlet, sequentially flows back between the cathode pressing plates and the anode plates to form a passage and flows out from the water outlet. The reaction mass transfer efficiency and the reaction path are increased by utilizing the disc type design, and the reactionefficiency of sodium hypochlorite production is improved; the electrodes adopt a cathode and anode staggered lamination mode, so that the reaction efficiency is enhanced; and the reactor shell and the internal electrodes adopt a high-pressure sealing mode, so that the dissolution rate of chlorine can be effectively improved, and chlorine leakage is avoided. The method has good sodium hypochloriteproduction capacity, and can significantly improve the concentration of sodium hypochlorite in water.

Rotating-manipulation device

Disclosed is a rotating-manipulation device provided with a rotating-manipulation member (10), and a rotation detection switch (14) that detects the direction and amount of the rotating-manipulation, wherein the rotation detection pitch of the rotation detection switch (14) can be reduced while assuring normal operation thereof. The rotating-manipulation member (10) comprises a plurality of switch driving sections (20) arranged in the circumference direction thereof. The rotation detection switch (14) comprises a detector (30); and a switch body (32) that holds the detector (30) movable in a first moving direction and a second moving direction, which are opposite directions of each other with respect to a prescribed origin position, and outputs a detection signal each time the detector (30) moves. The rotation detection switch (14) is arranged so as to take a posture that makes the moving direction of the detector (30) nearer to an orthogonal direction with respect to the rotating circumference direction of the rotating-manipulation member (10), rather than the rotating circumference direction thereof. Each of the switch driving sections (20) has a shape that moves the detector (30) for a prescribed distance or more in the first moving direction or the second moving direction, in accordance with the rotation of the rotating-manipulation member (10), and then releases the detector (30).
