Patent JP-S6486541-A (JP)
Title: Heat-conductive module
Inventor: DEEBUIDO HOON
IPC: H01L23/40
Filed: 1987-10-24
Abstract: PURPOSE: To provide effective thermal contact between an electric element and an exposed end surface of a piston, by causing the piston to be pushed against the action of a spring device combined with the piston, extruding a grease-like medium to the exposed end surface of the piston, and causing the grease-like medium to flow between the exposed end surface and the electric element. CONSTITUTION: An exposed end surface 9 of a piston 4 of each thermal conduction module 26 thermally contacts associated electric elements 21, 22 from which heat is removed. The piston 4 protrudes against the action of a coil spring 6, and a grease-like medium 10 exudes from a through-hole 8 opening in the exposed end surface 9 and flows between the exposed end surface and the electric elements 21, 22 so as to realize effective thermal contact between the electric elements and the exposed end surface of the piston.  Since the grease- like medium having a high thermal conductivity substantially fills the space between the electric elements 21, 22 and the exposed end surface 9, the efficiency of thermal conduction from the electric elements to the piston under the spring load is improved, and the efficiency of thermal conduction to a thermal conductor 24 via a tubular housing 1 is also high.

Filed: 1992-09-09
Abstract: PURPOSE:To shorten the time required for focus searching by searching the focus while making an objective lens gradually descend after abruptly displacing the objective lens toward an optical disk by means of a focusing coil. CONSTITUTION:A pre-processing circuit 5 performs adding and subtracting processing of a reproducing output signal of an optical disk 2 from an optical pickup 4 so as to generate a focusing error signal FE and a reproducing signal, etc., and outputs these signals through an amplifier circuit 6.

Title: Stepping measurement apparatus of electronic clock
Inventor: YAMAZAKI SOUYA
IPC: G04D7/12
Filed: 1990-10-04
Abstract: PURPOSE:To exclude interference with an adjacent clock and to enable correct stepping measurement by cutting off the interference of leaking magnetic flux from the adjacent clock by magnitude comparison of timing data and level data of a clock circuit thereof. CONSTITUTION:A sampling clock is generated 22 and 23 by binary coded leaking magnetic flux signals 24 and 25 from a clock 15 and is output to A/D converters 24 and 25, and a FIFOs 26 and 27. At the same time, output of a counter 28 is also stored in the FIFOs 26 and 27. Subsequently, a CPU 10 reads out and compares counting values to search a value within a range of delaying extent of the circuit, and obtains a value caused by interfered leaking magnetic flux of the clock 15. Simultaneously, from the outputs of the converters 24 and 25, the maximum absolute value in the lever data which are close to the counting values of the FIFO 26, is obtained. The maximum absolute values of the FIFO 26 and 27 have apparent difference in between when interfered, and the maximum value of the FIFO 26 is several times larger because a sensor 16 is very close to the clock 15, when influenced by the leaking magnetic flux of the clock 15, and therefore the data of the FIFO 27 can be judged to be interfered one. By this reason, influence by the interference of the leaking magnetic flux can be excluded by exclusion of the FIFO 27 data.

Title: Infrared image pickup apparatus
Inventor: FUSHIMI NAOFUMI
IPC: G03B9/02
Filed: 1992-09-10
Abstract: PURPOSE:To obtain an image pickup apparatus where an image pickup element is not subjected to unnecessary infrared rays even if a condenser lens is replaced by providing a variable opening means (aperture) for limiting an incident angle of infrared rays to the image pickup element. CONSTITUTION:An infrared image pickup element (CCD for example) 1 is placed on a cold head 3 cooled by a cooling means. A condenser lens 8 and a column 9 are provided in front of an incident window 4. A variable aperture 2a is fixed under an aperture attaching part formed at the upper end of a cold shield 2. A size of an opening of the aperture attaching part is set to the smallest size with which a field of view is not eclipsed when a lens 8 having the largest infrared ray incident angle theta is attached. When the lens 8 is replaced with a one having a smaller incident angle theta, heat radiation is made incident on the image pickup element 1 from the lower end face on the column 9, the aperture 2a is stopped down to limit the infrared rays to the image pickup element 1 only to transmitted light of the lens 8. Thus, only the infrared rays from a subject are made incident, preventing external infrared rays from being recorded.

IPC: G01N29/22
Filed: 1991-09-19
Abstract: PURPOSE:To detect the size of a defect in a material to be inspected correctly with a smaller and low-cost apparatus by a method wherein an analog signal reflected from an internal defect or the like is stored temporarily and the maximum value thereof is detected at each frequency of sampling to be converted into a quantization signal. CONSTITUTION:A time-sharing analog signal reflected from inside a material to be inspected by an ultrasonic wave being radiated synchronizing a clock from a clock circuit 1 is applied to a peak detection circuit 6 via a receiving circuit 5 to store the maximum value thereof into a capacitor C temporarily being held for a fixed time. Receiving a clock command from the circuit 1, an A/D conversion circuit 8 operates to quantize the maximum value of the analog signal. On the other hand, the clock from the circuit 1 is applied to the circuit 6 through a delay circuit 7 and after the end of the operation of the circuit 8, it provides a command to a switch S. With the operation of the switch S, an electric charge stored in the capacitor C is discharged quickly to arrange the preparation for the sebsequent analog signal sampling. This enables accurate detection of a defect with a handy circuit without use of a costly and large high speed A/D converter or the like.

Abstract: PURPOSE:To obtain a signal distribution representing a desired membership function by setting a basic form of the membership function to an electric signal distribution generating circuit and applying on/off control to the basic form by means of a switch group of a bus array. CONSTITUTION:The membership function generating circuit 43 consists of a voltage distribution generating circuit 44 generating a prescribed voltage distribution on plural signal lines, a switch array 45 sending the generated voltage distribution onto a prescribed output signal line and a decoder 46 decoding a code representing a label read from the label memory 41 to control a switch of the switch array 45.
