Title: Tracking error detector
Inventor: OKAMOTO HIROSHI
IPC: H04N5/782
Filed: 1989-11-10
Abstract: PURPOSE:To obtain a tracking error with high accuracy by detecting a detection error cause due to an inter-gap distance error of two heads fed to the detection of a tracking error at still reproduction and correcting a phase difference detected at normal reproduction. CONSTITUTION:A correction device 8 stores an output phis of a phase difference detection means 6 when an output of an envelope detection means 7 and a phase difference detection means 6 is inputted and an output of the envelope detection means 7 is maximum at still reproduction. Then At normal reproduction, the phase difference phin detected from the means 6 corrects the phis to output the corrected value phin-phis as a tracking error. Thus, even When the gap between two rotary magnetic heads 1A, 1B used for detection the tracking error differs from that at recording, the effect is not received and a highly accurate tracking error is detected.

Title: Information recorder
Inventor: YOSHIMARU TOMOHISA
IPC: G11B7/125
Filed: 1988-11-21
Abstract: PURPOSE:To prevent destruction of information and damage to a recording medium by using a moving means so as to move a light collection means and to cause forcible defocus state on an optical recording medium and radiating a light beam from an optical output means. CONSTITUTION:An objective lens (collection means) 8 uses a lens actuator (moving means) 15 to be supported movably in its optical axis direction. The actuator is moved in a direction of the optical axis by a servo signal S2 from a focus servo circuit 16 and a laser beam is projected onto the surface of an optical disk 1 via a lens 8. Prior to the radiation from a semiconductor laser oscillator 5, the actuator 15 moves the lens 8 forcibly in the direction of optical axis to cause defocus state on the disk 1. Then a beam is radiated from the oscillator 5, then the light energy of the disk 1 is scattered and even if an abnormal light output is generated from the oscillator 5 due to a fault of an optical output control circuit 14, the destruction of the recording information is prevented.

Title: Heat insulating wall panel
Inventor: INOUE JIRO
IPC: E04B1/80
Filed: 1997-10-27
Abstract: PROBLEM TO BE SOLVED: To prevent surface dew condensation at four corner parts so as to improve heat insulating performance by disposing a heat insulating sheet formed of a high foam body, at four peripheral edge parts of the rear face of a face bar in a heat insulating panel with heat insulating material disposed at the rear face of the face bar excluding four peripheral edge parts. SOLUTION: In a heat insulating wall panel, heat insulating material 2 is disposed at the rear face of a face bar 1 formed of plywood, a fiber plate, or the like, excluding four peripheral edge parts. The heat insulating material 2 can take various forms, and fiber such as rock wool, a foam body such as an urethane foam body, or the like can be used as material. A heat insulating sheet 7 formed of a high foam body easily compression-deformed is disposed at the four peripheral edge parts of the rear face of the face bar 1. The heat insulating sheet 7 can be shrinkage-deformed by pressing force when the face member 1 is brought into contact with the surface of a column or a horizontal member 5 and pressed at the time of fitting the heat insulating wall panel to a framework.  This deformation therefore prevents surface dew condensation at four corner parts of the panel so as to improve heat insulating performance.

Title: Semiconductor device and its manufacture
Inventor: YOSHIHARA SHINJI
IPC: H01L21/306
Filed: 1993-10-29
Abstract: PURPOSE:To easily manufacture a semiconductor device by a method wherein a functional layer which functions as a semiconductor is formed of FeSi2 and an electrode for the functional layer is formed of FeSi. CONSTITUTION:A silicon substrate whose plane orientation is (111) is used as a semiconductor substrate 10. A semiconductor functional layer 20 which is composed of beta-FeSi2 and which functions as a thermistor is formed on the substrate 10. In addition, conductive electrodes 31, 32 which are composed of FeSi are formed on the functional layer 20. When they are manufactured, the beta-FeSi2 functional layer 20 and the FeSi electrode layers 31, 32 can be grown continuously by changing a temperature by using the same film formation apparatus. In addition, the beta-FeSi2 layer is formed on the Si (111) semiconductor substrate. However, since the resistivity of the beta-FeSi2 layer is smaller than that of the Si (111) substrate, the performance and the effect of the thermistor can be obtained even when the layer is not formed on an insulating substrate. Consequently, a semiconductor device can be manufactured easily.

Filed: 1986-12-11
Abstract: PURPOSE:To reduce the load of a CPU in a bank switching by detecting a bank boundary based on the position changes of old and new address and switching banks automatically. CONSTITUTION:A bank of a bank memory 3 is selected by a bank address counter 6 in i response to the initial designation of a CPU 1 and an access is given to the bank selected by the address given from the CPU 1.
