Patent JP-S62190839-A (JP)
Title: Exposing method
Inventor: SHIN DAISHIYOKU
IPC: H01L21/68
Filed: 1986-02-18
Abstract: PURPOSE:To miniaturize an integrated circuit and to improve the quality by removing a resist film coated on the alignment mark of a wafer by laser emitting, and then aligning a mask on the wafer to not only improve the alignment accuracy but also to increase a margin in an etching step. CONSTITUTION:Only a resist film 3 on a mark used in a specific masking step is removed by laser emitting to expose the mark. For example, an argon gas laser or a carbon dioxide gas laser is emitted to the film 3 coated on the alignment mark 2 of a wafer 1. This process is more effective by emitting the laser on the resist film while spraying an oxygen as than in vacuum. The laser emission is executed only on the mark used in the masking step on the wafer. The laser may be emitted in addition to the use of an exclusive laser emitting unit by employing a laser light source and an oxygen gas introducing hole in an exposure unit.

Title: Zero drift correcting method of sensors for car brake
Inventor: TAKADA KOJI
IPC: B60T8/00
Filed: 1986-02-18
Abstract: PURPOSE:To take in correct information and improve reliability by performing a reset operation only when predetermined conditions are met in a brake system performing control based on output signals from braking sensors. CONSTITUTION:The brake status is monitored, and if a predetermined delay time elapses after a brake is switched from On to Off or the brake is switched to On after an Off state is continued for a predetermined time or more, a zero adjusting section for a depression force sensor 7, liquid pressure sensors 8a, 8b and an amplifier 9 are driven. The brake status is sampled, and if a sampling signal or a sensor drive periodic signal is output while the Off state is continued for a predetermined time or more, the zero adjusting section is also driven. Accordingly, signals are taken into a CPU 5 with little zero drift, thus correct brake control can be performed.

Title: Power converter
Inventor: NAGAI TOMIYUKI
IPC: H02M3/28
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To eliminate unwanted operations to reduce power consumption by stopping the output of an output power supply when a timer which counts time from the start of a converting operation of a power converter has counted time for a specified period of time. SOLUTION: A timer 10 is controlled for its operation by a timer on/off switch 12. When the timer on/off switch 12 is turned on, the timer 10 starts counting and a latch state of a latch circuit 11 is reset to a low level. When the timer 10 finishes timing for a specified period of time, the output of the timer comes to a high level. Then, an output control signal of a photo coupler 8 becomes high level. After the passage of a set insensitive time, the latch circuit 11 latches the high level state and a switching control signal supplied from a control circuit 9 to a switching section 3 is fixed at a low level. Therefore, the output of DC voltage from a rectifier circuit 5 is cut off. Due to this structure, there is no unwanted operations of circuits and the power consumption can be reduced.

Abstract: PURPOSE:To perform tracking free from the effect of residual distortions by applying the AC voltage of specified amplitude upon completion of position correction to  an electro-mechanical transducer such as bimorph piezoelectric element or the like  for head position correction. CONSTITUTION:The electric field of a specified direction through the adder 17, drive circuit 18 of an oscillator 16 is applied to the piezoelectric element 19 of bimorph plate according to the feedback signal of the level corresponding to the tracking position of a head 19 through a synchronous detection circuit 23, whereby the head 19 is corrected to the tracking position. When the connection of a switch 14 is changed over after the completion of this correction, the electric field 0.25 to 0.75 times the anti-electric field E at the magnetic erasing rate 100% of the element 19 is applied from an attenuation AC signal generator 32 to the element 19 via circuit 18, thus the tracking of the head 20 is accomplished via the element 19 in the state where there are virtually no residual distortions. As a result, the good tracking free from the effect of the residual distortions of the piezoelectric element, etc. is performed.

Title: Semiconductor laser
Inventor: ITOU KUNIO
IPC: H01S5/20
Filed: 1980-03-19
Abstract: PURPOSE:To realize single-mode oscillation with ease by holding an active layer between two curved parts at the position above the level-difference part of a substrate. CONSTITUTION:When the active region is made to have a difference in thickness, there occurs a large difference in refractive index and thereby the condition for a single mode is narrowed. Therefore, the thickness of the active region is made to be fixed both in a part immediately above the level-difference part and in the flat part thereof or to be smaller by several percents in the bend part thereof, and thus it is made to vary moderately with some curvature. Accordingly, the difference in refractive index between the curved part and flat part of the active region depends only on the thickness of the 1st clad layer located between the active region 10 and the substrate 8, and thus it becomes a small value of the about 10<-5>. Therefore, even when the length between two curved parts is extended to about 5mum, the oscillation of a single horizontal mode is possible. In order to confine electric current effectively in the active region 10, it suffices when a cap layer 13 is formed to be n-GaAs, Zn diffusion 14 is performed and thus a part of a diffused front is formed to reach p-Ga1-xAlxAs 11.

Title: Circuit for controlling drive for master disk recorder
Inventor: NUNOMURA TOYOYUKI
IPC: G11B19/28
Filed: 1988-02-19
Abstract: PURPOSE:To set a track pitch with high accuracy by dividing original clocks with 1st and 2nd dividers and respectively using the outputs of the 1st and 2nd dividers as the reference clocks of a rotation driving mechanism and feeding mechanism. CONSTITUTION:Original clocks generated from an original clock generating section 1 are divided into 1/N by means of a divider 2 and reference clocks CF are formed and divided into 1/M by a divider 3 and reference clocks CSP are formed. Then motor speed signals C'F which are proportional to the rotating speed of a head feeding motor 8 are phase-compared with the reference clocks CF at a phase comparator 4 and the rotating speed of the motor 8 is controlled by means of the phase error signal produced as a result of the comparison. Similarly, motor speed signals C'SP which are proportional to the rotating speed of a master disk rotating motor 9 are phase-compared with the reference clocks CSP at a phase comparator 5 and the rotating speed of the master disk rotating motor 9 is controlled. Therefore, even if the frequency of the original clocks changes, the frequencies of the reference clocks CSP and CF simultaneously change and the rotating speed of a master disk is always maintained in a fixed state and, as a result, the track pitch is maintained constantly.

Title: Flat cable tester

IPC: G01R31/08
Filed: 1985-02-25
Abstract: PURPOSE:To obtain a tester capable of performing withstand voltage inspection, by changing over the connector terminals of a flat cable by a switch even when the arrangement of said connector terminals is different. CONSTITUTION:Voltage Vt for inspecting withstand voltage is applied to per form the usual inspection of connectors 2 having the arrangement of terminals 5 and, when the plus side of the voltage Vt for inspecting withstand voltage is applied to the right side terminals 5, a change-over switch 7 is preliminarily changed over to the side of a contact (a). Because the contact (a) is connected to the line of terminals 5 of the connector 2 to which the minus side of voltage Vt for withstand voltage was applied at this time, a leak current detection circuit 6 also comes to minus potential and no current is flowed to the leak current detection circuit 6 unless a leak current flows. However, in the flat cable having the connector 2 different in the arrangement of the terminals 5 shown by a drawing, voltage having inverse polarity appears in the other terminal of each terminal line. Therefore, by changing over the switch 7 to a contact (b), correspondence can be realized.
