Title: Optical reader
Inventor: OOKI YUTAKA
IPC: G02B7/28
Filed: 1982-10-26
Abstract: PURPOSE:To perform easily the positioning and adjustment of photodetectors and to improve detecting sensitivity by separating a part of a center part and a part of a peripheral part at least out of returning light flux from a beam splitter in different directions and guiding respective light rays to respective photodetectors. CONSTITUTION:The light flux from a semiconductor laser LD is focused like a spot on a disc D and the returning light flux reflected by the signal surface passes through an optical path reversely, turns its optical path from the deflecting beam splitter 12 to an auxiliary lens 15 side and is made incident to a space dividing half mirror 16. The light reflected on a center part 16a of the mirror 16 is made incident to a photodetector PD1 and the light passing through a peripheral part 16b is made incident to a photodetecor PD2. Consequently, the positioning of the photodetectors can be easily adjusted and the detecting sensitivity can be improved by reducing the diameter (b) of the center part 16a of the space dividing half mirror 16.

Abstract: PURPOSE:To improve the cooling efficiency by a method wherein a fin forming a circulation path for circulating a refrigerant to each semiconductor device is installed and additionally its outer circumference is covered with a magnetic seal having a magnetic fluid so that the fin can be attached and detached from a cooling plate. CONSTITUTION:A fin 6 which is equipped with a circulation path 5A for a refrigerant in its inside is fixed to the surface of a semiconductor device 2 which is mounted on a printed-circuit board 1 by welding, glueing or soldering so that an outer circumference 5B of the fin 5 can be covered with a magnetic fluid 6A which is held by an N magnetic pole 8A and an S magnetic pole 8B. The refrigerant which has flowed through a flow path 3A at a cooling plate 3 in the direction as shown by an arrow F1 flows through a nozzle 11 into the circulation path 5A as shown by an arrow F2. The refrigerant flows from the circulation path 5A in the direction as shown by an arrow F3 so that the refrigerant does not leak due to the interception of the magnetic fluid 6A at a magnetic seal 6. Therefore, the refrigerant can flow directly through the fin 5. In addition, because a part E where the surface of the semiconductor device 2 comes into contact with the fin 5 is fixed, the thermal conductivity is increased and the cooling efficiency can be improved.

Filed: 1989-07-20
Abstract: PURPOSE:To prevent invasion of reflected noise due to the deflection control of a CRT by providing a sampling clock forming means forming a sampling clock having a frequency of an integral number of multiple of that of a horizontal synchronizing signal synchronously with the horizontal synchronizing signal, and supplying the sampling clock to an A/D converter. CONSTITUTION:A sampling clock having a frequency of an integral number of multiple of that of a horizontal synchronizing signal synchronously with the horizontal synchronizing signal is formed by a sampling clock forming means 36 based on a control clock and supplied to a control circuit 37 and an A/D converter 22 uses the clock to convert an audio signal into a digital signal. A voltage induced by the deflection of a CRT and the sampling clock are both synchronous with a horizontal synchronizing signal of a video signal and the difference frequencies are two frequencies as OHz and fH at an audio signal band such as '0'-20kHz. Thus, when a signal pass band of the processing unit is selected as 20Hz-10kHz, the reflecting noise of the said different frequencies is not invaded in a signal within the band. Thus, the invasion of the reflected noise due to deflection control of the CRT is prevented.
