Title: Resin coated sheet
Inventor: NAKAGAWA KUNIYOSHI
IPC: B32B27/12
Filed: 1993-01-28
Abstract: PURPOSE:To provide resin coated sheet, in which no resin separation develops even when the sheet is woven of long untwisted fiber yarns. CONSTITUTION:The resin coated sheet concerned is produced by covering base fabric, which is woven of fabric using long untwisted polyester fiber yarn having the single yarn denier of 8 D or more, the strength of 7g/D or more, an elongation of 20% or more and the dry thermal shrinkage factor of 7% or less as warp and woof so as to have the woven voids of 10% or more, with synthetic resin. Thus, since the long polyester fiber yarn, which is low shrinkable and has converging properties at low count, is used, weaving can be carried out by employing untwisted thread as warp and woof, resulting in omitting pre-setting process and twisting process and making the reduction of production cost possible.

Title: Signal processing circuit
Inventor: TOBA YOSHITOMI
IPC: H04N9/44
Filed: 1979-03-26
Abstract: PURPOSE: To prevent a circuit from being operated erroneously for noise, by providing a gate, which makes the input signal ineffective for a fixed time, in the input of a counter.  
     CONSTITUTION: In case that a gate signal to extract a VIR signal is formed in the television receiver, horizontal synchronizing signal SH is inputted counter 1, and vertical synchronizing signal SV is inputted to count set inhibition circuit 4. Counter 1 performs count when reset terminal R is L-level. Decoder 2 forms a gate signal corresponding to the count value. The count set inhibition circuit is constituted by a monostable multivibrator and an AND circuit and outputs the L-level from the rise of the vertical synchronizing signal to the time just before input of the next vertical synchronizing signal and makes counter 1 into the operation state. Counter 1 is reset by the decoder output after that. Since counter 1 operates only in count times t 1 ∼t 11 , the circuit can be prevented from operating erroneously in other times.

Inventor: KOMURO AKIRA
IPC: H01S5/00
Filed: 1978-03-23
Abstract: PURPOSE: To reduce the stripe width and thus to reduce occurrence of the strain, defect and other negative factors by introducing the diffusion technique to the mesa- type stripe structure.  
     CONSTITUTION: The n-Ga 1- XAlXAs layer 2, n-GaSa layer 3, p-Ga 1- XAlXAs layer 4 and p-GaAs layer 5 are laminated in that order onto n-GaAs substrate 1. The mesa-type etching is given to both ends n-GaAs substrate 1. The mesa-type etching is given to both ends of layer 5, and the accumulation layer of stripe type is formed on layer 4. Then Zn is diffused from the surface of layer 4 to form Zn diffusion layer 13. The diffusion front of Zn is stopped inside layer 5 for the region to which the diffusion is given from the surface of layer 5, and reaches inside of layer 2 for the region to which the diffusion is given from the surface of layer 4 respectively. And the current flows with the region of layer 3 where no Zn diffusion is given used as the passage owing to the difference of the energy barrier to the electron. Thus, the current path is limited within the active layer, obtaining an extremely narrowed laser oscillation region.

Abstract: PURPOSE:To manufacture of a high-quality record carrier of simple structure in a short time by arranging a substrate on a stamper while a gap is left, charging and rolling an adhesive in the gap and curing the adhesive, and uniting the adhesive and substrate together. CONSTITUTION:The transparent substrate 3 is vacuum-sucked onto a substrate base 10 so as to face concentrically the stamper 1 which is installed horizontally. Then, a discharge pipe 9 is inserted into the gap between the transparent substrate 3 and stamper 1. Then, the stamper 1 and transparent substrate 3 are rotated by a motor 16 synchronously and ultraviolet-ray setting resin 5 is discharged from the discharge pipe 9 at the same time. The ultraviolet-ray setting resin is viscous, so the resin after falling on the stamper 1 swells to contact even the transparent substrate 3, so that the resin is charged in a ring shape by the rotation. Then, the ultraviolet-ray setting resin is rolled and cured. Thus, the adhesive is charged in the gap alpha between the stamper 1 and transparent substrate 3, so an overlaying process in which the formation of an air bubble may be caused is not necessary and the excellent information record carrier having no defect due to air bubbles is obtained in a short time.

Title: Switching power supply
Inventor: YAMAGUCHI HIROYUKI
IPC: G05F1/10
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To enhance efficiency while reducing the size by driving a switching element at a high switching frequency, when the ripple voltage is higher than a threshold and driving it with a low switching frequency, thereby when the voltage is lower switching the switching frequency automatically depending on the load conditions. SOLUTION: Ripple voltage of a primary smoothing capacitor C1 is low, when the load is light, and is increased when the load is heavy. A signal of H level is delivered from an output terminal c, when the ripple voltage detected at the detection terminals a, b of a ripple voltage detection circuit 5 is lower otherwise a signal of L level is delivered. Upon receiving the signal of H level, a switching frequency switching circuit 2 operates a PWM control circuit 1 at a low switching frequency and operates it at a high switching frequency upon receiving the signal of L level. Since the switching frequency can be switched automatically depending on the load conditions, the switching power supply can be reduced in size while enhancing the efficiency.
