Title: Direct current arc welding machine
Inventor: OONISHI SHIYUNSAKU
IPC: B23K9/06
Filed: 1979-05-11
Abstract: PURPOSE: To enable the stable welding in a wide current region with one DC reactor by parallel connecting a smoothing circuit which includes a capacitor and an impedance circuit which does not include any capacitor to a fusion-welding electric power source.  
     CONSTITUTION: When contacts 2 are closed by the operation of a torch, an AC power source 1 is supplied to a welding transformer 3 and its output is made to direct current by a rectifying circuit 4. This direct current is applied to a welding electrode 10 by way of the main winding of a DC reactor 4. The smoothing capacitor 6 during welding repeats charging and discharging and after the end of the welding, it is discharged through a resistance 14. As a result of this, even if an arc 12 is held put out, the specified load current flows through a control winding 13 and resistance 14, and the no-load voltage generated between the electrode 10 and base material 11 becomes lower. When current supply to the load side of the transformer 3 is stopped by opening the contacts 2, the charges having been charged into the capacitor 6 are discharged through an impedance circuit C. This circuit constitution eliminates the pulsation of the current in the spray arc welding region and stabilizes the arc.

Title: Manufacture of distributed feedback semiconductor device
Inventor: YAMAGUCHI MASAYUKI
IPC: H01S5/00
Filed: 1989-03-08
Abstract: PURPOSE:To improve reliability by causing a guide layer to grow by LPE(Liquid Phase Epitaxy) and an active layer to grow by MO-VPE(Metal Organic Vapor Phase Epitaxy). CONSTITUTION:A diffraction grating 5 with periods of 2400Angstrom  is formed by luminous flux interference exposure of a laser 2 on an n-type InP substrate 1 and an n-type InGaAsP guide layer 2 with wavelengths of 1.15mum is formed to 0.1mum thickness by LPE. Further, an n-type InP buffer layer 6 having the thickness of 0.05mum, an MQW active layer 3, a p-type InP clad layer 4 having the thickness of 1.5mum, and a p-type InGaAsP cap layer 7 having the thickness of 0.5mum are formed one after another by MO-VPE. A multilayer semiconductor layer, with the exception of a stripe-like region which intersects at right angles to the grating 5, is etched in such a way that its etching is deeper than the depth of the layer 3 and then, a mesa-stripe 8 is formed. After that, a high resistance InP layer in which iron is doped by MO-VPE is formed so that the side face of the stripe 8 as well as the surface of the substrate 1 are covered and electrodes 9 and 10 are formed on both surfaces of the semiconductor. In this way, no dislocation takes place and a generated threshold current is low and superior reliability is obtained.

Title: Automatic applying device of highly viscous liquid
Inventor: KIUCHI ISAO
IPC: B05C5/00
Filed: 1982-04-08
Abstract: PURPOSE:To enable automatic application of adhesive etc. to the periphery of a work conforming to uneven shape of the work by supporting a rotary stand on which a work such as window glass etc. is placed by an elastic body such as forming urethane allowing vertical movement. CONSTITUTION:After mounting a work W on a rotary stand 4, a lifter 10 is lowered and a nozzle 13 is brought into contact with the work W. When a motor 2 is driven to rotate a shaft 27, the rotary stand 4 rotates, and at the same time, a sealing agent is sent out from the nozzle 13 by a coating machine 9. At the same time, if a changing point of curvature in vertical direction appears in the work W, the work is pushed down by the nozzle 13. However, the amount of change is absorbed by an elastic body 5. As a guide plate 19 advances between a sprocket 26 and a roller 20, the rotary stand 4 rotates bringing the periphery of the work W right under the nozzle 13.

Filed: 1985-03-20
Abstract: PURPOSE:To enhance effective utilization efficiency to the positional detection of light from a light projection means, by allowing all the light from a light emitting element to be incident on a light receiving means through slits under the rotation of a slit rotary member. CONSTITUTION:All the light from a light emitting elements 30 are directly incident on the ring shaped light receiving part 42a of a photoconductive membrane 42 as spot light from a slit 22b through a rod shaped rotary member 20. Therefore, in detecting the opening degree of a throttle valve, the light from the light emitting element 30 is effectively utilized without wastefulness and, as a result, the effective utilization efficiency of the light from the light emitting element can be enhanced. Further, because the light from the light emitting element 30 is projected to the opening 22a of the rod shaped rotary member 20 through an optical fiber 80, the light emitting element 30 can be placed at an area separated from a casing 10 and, therefore, it is unnecessary to expose the light emitting element 30 to a high temp. atmosphere, therefore LED can be used.

Filed: 1991-03-20
Abstract: PURPOSE:To encode image data even without executing variable length encoding by deciding a quantizing threshold value for encoding the image data so as to obtain a desired code amount. CONSTITUTION:A linear quantizing part 3 quantizes the image data while dividing respective MXN of DCT coefficients per block outputted from a two-dimensional DCT transformation part 1 with the NXM of correspondent quantizing threshold values q(i), and a valid coefficient storage part 7 cumulates the number of valid coefficients contained in the quantized DCT coefficients obtained by quantization and calculates a total number (n) of valid coefficients for one picture. While using relation between the code amount and the number of valid coefficients, a code amount/valid coefficient transformation part 8 calculates a total number (m) of valid coefficients for one picture according to a designated code amount F. A quantizing threshold value decision part 9 decides the quantizing threshold value q(i) so that difference between the number (n) of valid coefficients for one picture and the number (m) of valid coefficients obtained based on the designated code amount F can be settled within a set range, and the image data are quantized by using the quantizing threshold value q(i) and encoded by a variable length encoder part 6.

Title: Antiferroelectric liquid crystal display
Inventor: YAMAZOE HIROSHI
IPC: G02F1/133
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To enable display with a large visual field angle and to obtain a display optimum for a monitor, etc., by forming the driving waveforms of an antiferroelectric liquid crystal panel to two stages and impressing a pulse of a large crest value first. SOLUTION: For example, the display of light transmittance (j) is assumed to be executed. At this time, the display attains the light transmittance of (j) when voltage (h) is impressed, but the time for attaining the transmittance at a low temp. is too long. At this time, the voltage (i) larger in the absolute value than the voltage (h) corresponding to (j) is impressed for a short time and thereafter, the voltage (h) is impressed. As a result, the initial torque of liquid crystal molecules is made large by (i) large than the voltage (h). Then, the array of the liquid crystal molecules corresponding to the desirable light transmittance (j) is attained earlier. Namely, the remarkable improvement of the response of the liquid crystal molecules at the low temp. is made possible.  The light transmittance is instantaneously made higher than the desirable light transmittance (j) by the voltage (i) in some cases. If τa is sufficiently smaller than τappl, there is no damage to be incurred.
