Patent JP-S61187278-A (JP)
Title: Semiconductor device
Inventor: SAITO AKIRA
IPC: H01L29/812
Filed: 1985-02-14
Abstract: PURPOSE:To reduce inductance while preventing the lowering of effective capacitance by forming a capacitor formed by an electrode pattern on one main surface and a metal on the other main surface shaped through a dielectric to a pellet containing a GaAs field-effect transistor. CONSTITUTION:Upper electrodes 1 on a main surface containing GaAs 3, back electrodes 2 and an interposing dielectric 4 are shaped. GaAs 3 it etched, and capacitances C1, C2 are formed. Since the back electrodes 2 are all connected to a grounding surface at the same potential at that time, wiring electrodes are unnecessitated, and there is hardly inductance intruding in series between the capacitances C1, C2. Accordingly, source inductance intruding in series can be ignored approximately, thus allowing a design only by the thickness of the dielectric and electrode width of effective capacitance.

Title: Method for returning to origin
Inventor: MUTO MORIO
IPC: H02P3/00
Filed: 1986-02-10
Abstract: PURPOSE:To limit the number of sensors to one and to prevent malfunction without adversely affecting wiring, etc., by installing an origin position discriminating part on the periphery of a disk and a deceleration point position decision part on both sides. CONSTITUTION:An origin sensor 2 is arranged on the outer periphery of the disk with a slit 1, and detects deceleration point slits 7 and 9 and an origin slit 8. When returning to the origin start, the disk 1 rotates in a positive direction by theta deg. with 2alpha<theta<360 deg. given in order to be out of a range of an angle 2alpha until the sensor 2 is turned on. Thus the sensor 2 does not fall on the slits 7, 8 and 9. Then, when the disk 1 reversely rotates to turn on the sensor 2, it is decelerated. At the time of the 2nd turning on, a motor controller 5 controls a motor driver 4 to stop a motor 3. Thus return to the origin can be made without malfunction even if the sensor 3 lies within the range of the angle 2alpha made by three slits. One sensor suffices and malfunction can be prevented without adversely affecting wiring etc.

Title: Control of feed cutter and system therefor
Inventor: SUMIHAMA TAKAHIRO
IPC: B23D25/12
Filed: 1978-03-13
Abstract: PURPOSE: To prevent cutting length error from occurring dependent on the thickness of the materil to be cut through obtaining the optimum circumferential speed of a cutting blade and starting timing signal and through making computation on the basis of the thickness of said material.  
     CONSTITUTION: Cutting at the cutting point of the material to be cut 4 is made by the cutting blade 2 provided on a cutter drum 1. In this case, the circumferential speed of said cutting blade 2, i.e. of said cutting drum 1, is determined in consideration of the distance l 1  between the center of said cutting drum 1 and a material detector 5, the cutting length l 2  and feed speed VB of said material 4, and the circumferential distance lSO between the starting position of said cutting blade 2 and said cutting point. However, the contacting position of said material 4 with said cutting blade 2 deviates forward over distance ΔlB and in angle ΔlS due to the thickness h of said material 4. For eliminating cutting length error, the timing of said cutting blade 2 is determined by making computation in consideration of values of said distance ΔlB and abgle ΔlS.

Abstract: PURPOSE:To reduce the occupation area of the magnetic sensing element by the size reduction and simplification of a fixed holder and to obtain excellent output characteristics by setting the moving direction of a movable holder at right angles to the magnetic sensing surface of the magnetic sensing element. CONSTITUTION:This holder consists of the movable holder 3 which holds a magnetic sensing element 4 where a lead frame 5 as a flexible signal input member is connected, the fixed holder 2 which holds a holder 3 fixed to a substrate 1, and guide means 2b and 2b which guide the holder 2 movably between those holders in one direction, and the moving direction of the holder 3 is set at right angles to the magnetic sensing surface 4a of the element 4. Consequently, the gap between the element 4 and a magnetic recording medium 9 is adjusted by observing the output of the element 9 while rotating a magnetic drum 8 and moving the holder 3 toward the element 9 until a proper output is obtained. Therefore, the holder 3 is only moved in one direction to the holder 2 and the bent part 5b of the frame 5 is flexible, so the gap is adjusted by moving the holder 3 toward the element 9.

Title: Reproduction apparatus for on-vehicle recording medium
Inventor: TAKEUCHI TORU
IPC: G11B33/02
Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To allow a control panel to be manually tilted so that a tilting motor becomes unnecessary by providing a click feeling providing mechanism so as to obtain a click feeling when the control panel is tilted to a recording medium ejection position. SOLUTION: A resin block 51 is fixed at a lower end of a bracket 32, and a hook 53 is provided at a tip of the block 51. When a detachable control panel(DCP) 3 is tilted, the hook 53 is pushed to be spread out by a roller 35 in a direction indicated by an arrow. When the DCP 3 is tilted to be at a recording medium ejection position, the hook 53 moves beyond the roller 35 and is repulsed in the direction of the arrow to be pushed back. In this case, an operator who is tilting the DCP 3 obtains a click feeling. Accordingly, the hook 53 of the block 51 constitutes a click feeling providing mechanism. The hook 53 of the block 51 functions to resist against the roller 35 after once being engaged with the roller 35, thereby preventing the DCP 3 from unexpectedly moving.

Title: Master-slave system transmission equipment
Inventor: NAKAI ICHIRO
IPC: H04W16/24
Filed: 1989-02-07
Abstract: PURPOSE:To use the transmitter at a mobile equipment side while being moved between zones without requiring switching operation of a channel by allowing a slave transmitter to trace its transmission frequency to a transmission frequency from a master transmitter. CONSTITUTION:When a transmission frequency of a voice signal of a master transmitter 1 are sent to plural slave transmitters 2 from a master transmitter 1 through a transmission line 10, a separator 11 separates the components of the transmission frequency and the voice signal and when a transmission wave detector 25 detects the transmission frequency component, a switch 23 selects the input of a phase comparator 13 from a reference oscillator 12 to a frequency divider 18. Since the same frequency division ratio as a frequency divider 16 is set to the frequency divider 18 by a frequency setting device 19, the frequency synthesizer of the slave transmitter 2 generates the transmission frequency coincident with the transmission frequency of the master transmitter 1 regardless of the frequency setting of the slave transmitter 2. Thus, the transmitter can be used at the mobile equipment side while being moved between zones without requiring operation of channel changeover.
