Title: Semiconductor light emitting element
Inventor: NOMURA HIDENORI
IPC: H01S5/042
Filed: 1983-03-10
Abstract: PURPOSE:To enhance the yield and reliability of a semiconductor light emitting element by stepwisely varying the thickness in the vicinity of a hole for a current injection part of an insulating film, and reducing the thickness of the insulating film in the boundary of the hole of the current injection part smaller than that of a metal for preventing the reaction of electrodes. CONSTITUTION:A buffer layer 2 made of N type InP, an active layer 3 made of In0.74Ga0.26As0.56P0.44, an enclosed layer 4 made of P type InP, an electrode forming layer 5 made of P type In0.86Ga0.16As0.36P0.64, an insulating film 6 made of SiO2 and having a current injection hole 6a and a stepwise part 6b, an ohmic contact layer 7 made of Ti, an electrode reaction preventing layer 8 made of Pt, and an Au-plated layer 9 for bonding a heat sink are sequentially laminated on a semiconductor substhate 1 made of N type InP, and an N type side electrode 10 made of Au-Ge-Ni alloy and having a light emitting window 11 is further provided. Then, the thickness of the film 6 is varied stepwisely near the hole 6a of the current injection part, and the thickness of the boundary of the hole 6a is formed thinner than approx. 0.05mum and 0.2mum of the layer 8.

Title: Chrominance signal converter
Inventor: TANAKA KAZUYOSHI
IPC: H04N9/74
Filed: 1987-02-23
Abstract: PURPOSE:To improve the precision of conversion and the conversion speed by providing three frame memories, a lookup table means, three latch means where picture data is latched, and an adder and operating multiplication with the look-up table means and operating addition with the adder. CONSTITUTION:A look-up table in a ROM 24 uses picture data from a latch circuit 20 as an argument to generate picture data whose value is obtained by multiplying the argument by a prescribed coefficient. For example, conversion formulas of YUV RGB are R=Y+1.403V, B=Y+1.773U, and G=1.704Y+(-0.509)R+(-0.194)B. Consequently, a relatively small-capacity memory having 5k-Ward storage capacity is sufficient as the ROM 24. An adder 26 adds picture data from the ROM 24 and the picture data from a latch circuit 22. The multiplication and addition of digital picture data are quickly processed with hardware in this manner to improve the conversion precision as well as the conversion speed.

Abstract: PURPOSE:To provide the title sensor withstanding impact force and made repeatedly usable by positioning a movable permanent magnet between the fixed permanent magnets in a main body case in a manner freely movable in the longitudinal direction of said case and making the magnetic poles thereof opposed to the fixed permanent magnets the same with each other. CONSTITUTION:Fixed permanent magnets 3, 3 are inserted in the main body case 2 of this sensor 1 so that the magnetic poles thereof become parallel to the longitudinal direction of the case and the same poles thereof are in the same direction and mounted to both side ends of said case 2. A movable permanent magnet 4 is arranged between said magnets 3, 3 in a state freely movable in the longitudinal direction so that the magnetic poles thereof opposed to the magnets 3, 3 are same and become repulsive each other and becomes a levitated stage almost at the center of the case 2. When external force is applied to this sensor 1, impact force acts on the magnet 4 and the magnet 4 reciprocally moves within the case 2 in the axial direction. At this time, the flux density piercing a Hall element 5 is changed by the displacement of the magnet and Hall voltage is generated in the element 5 and impact force can be measured on the basis of this change.

Title: Touch sensor for displacement detection
Inventor: MATSUHASHI AKIRA
IPC: G01B7/00
Filed: 1985-02-28
Abstract: PURPOSE:To improve repeatability and durability, by applying an HF voltage on a sensor. CONSTITUTION:When a specimen 8 is not touching a sensor 1, a voltage from the DC source is converted to an HF voltage by an HF oscillating circuit and introduced into a rectifying circuit 4 through a switch circuit set inside the sensor 1 and after rectification, it is amplified by an amplifying circuit 5 and fed after energization to a voltage necessary for sensing of the controlling circuit by an output circuit 6. When the specimen 8 is touching the sensor 1, a switch which is set inside is released and a voltage which has been applied to the circuit 4 is brought to a zero potential to feed out an indicating signal to a controlling circuit from a relay 7. By application of an HF voltage to a junction of the switching circuit of the sensor 1, problems of durability involved in the DC specification and repeatability in case of the AC specification can be solved.
Patent JP-S60187276-A (JP)
Title: Load drive device
Inventor: NINOMIYA JIYUICHI
IPC: H02P27/08
Filed: 1984-03-05
Abstract: PURPOSE:To smoothly rotate a motor without stop by transmitting a signal for accelerating the speed of the motor when a signal from pulse generating means is not produced during a sampling period. CONSTITUTION:If the rotating speed of an induction motor 6 is delayed, the period of the output 23S of a pulse converter 23 increases longer than the period of the output 22S of a timer 22. Thus, the counting of a counter 21 increases by one whenever a signal is output from the timer 22. This trend continues until a next pulse is produced from the converter 23. Accordingly, the output of a magnitude priority circuit 50 increases. Since a calculator 52 divides the output of the circuit 50 by the output of a speed signal converter 10, the output of the calculator 52 gradually decreases during a period until next pulse is input from the converter 23. Accordingly, the output of a calculator 11 gradually increases to operate to accelerate the speed of the motor 6.
