Title: Optical memory device
Inventor: FUJI HIROSHI
IPC: G11B11/10
Filed: 1985-10-08
Abstract: PURPOSE:To obtain an excellent recording characteristic and a satisfactory reproduction signal by recording a mark part so as to be an unrecorded part and detecting the interval between the unrecorded parts so as to reproduce information. CONSTITUTION:At the time of recording a signal, a recording laser beam P1 emitted from a semiconductor laser 2 is intensity-modulated by an RZ system that the bit length L1 of a recording part is made longer than the bit length L2 of the unrecorded part so that the mark is made into the unrecorded part. As a result, the temperature of a magnetic film on a disk 1 partially rises only the higher intensity part. In the temperature rising part its coercive force drops and the direction of magnetization is inverted when an auxiliary magnetic field is impressed from the outside. Then the bit 20 of the recording part corresponding to the recording laser beam P1 is formed on the disk 1. When the unrecorded part 21 being a mark is detected by a light spot 22 at the time of reproducing the signal, the difference between the recorded part and unrecorded part can be taken larger than that by the RZ system, whereby the reproduction signal S1 can obtain a larger amplitude. Thus the sufficient bit 20 of the recording part can be formed on the disk 1, thereby obtaining the satisfactory reproduction signal S1.

Title: Checker head
Inventor: GOTO YOSHITAKA
IPC: G01R1/067
Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To provide a checker head wherein a pitch between pins can be reduced with reduced number of parts. SOLUTION: A spring 14 is arranged in a little compressed state between a pin 10 and a rear surface panel 22 to push back the pin 10 by the elasticity of the spring 14 at the time of pushing the pin 10 to the test pad of a printing circuit. Continuity from a conductor 15 to the test pad is surely obtained by this pushing back. As a socket with a wire is not used here, a pitch between pins is reduced. In addition, as the number of board materials such as a rear surface board 20 and an intermediate board 21 is small, positioning precision is improved and this also contributes to the reduction of the pitch between the pins. In addition, as the number of the board materials is small, assembling is easy to contribute to the reduction of number of parts.
