Patent JP-H02217046-A (JP)
Title: Demodulator
Inventor: SATO KAZUMASA
IPC: H04L27/22
Filed: 1989-02-17
Abstract: PURPOSE:To shorten a leading-in time by selecting a fixed voltage by a switch circuit when a carrier synchronism detecting circuit detects the asynchronism of a reproduced carrier, and supplying the selected voltage to a discriminator. CONSTITUTION:An automatic gain control(AGC) signal (g) obtained by detecting the deviation of a signal point of a base band signal from a discrimination level by the discriminator 2 is supplied to an AGC circuit 6 and control voltage (h) is supplied from the circuit 6 to the discriminator 2 as control voltage (k) through a switch circuit 7 to control the amplitude of the base band signal to a fixed value. When an output signal (i) from an APC detecting circuit 3 is inputted to the carrier synchronism detecting circuit 5 and the synchronism is detected, the switch circuit 7 selects the fixed voltage by the output (j) of the circuit 5 and the output voltage (k) held at the fixed voltage is supplied to the discriminator 2. Consequently, the control voltage (k) of asynchronism is equal to that of synchronism and the leading-in time can be shortened.

Title: Device for conveying works at intervals in alignment
Inventor: MURAMATSU MICHIHARU
IPC: B65G47/30
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To keep constant the traveling speed in the conveyer cross direction of works for uniform intervals by supporting a guide roller so as to rotate in a horizontal plane at a small distance from a conveyance surface, and bringing the works into contact with the outer periphery of the guide roller at a fixed position so as to be rotated. SOLUTION: Works (a) on the conveyance surface of a conveyer belt 1 are guided to a fixed guide plate 5 and a movable guide plate 9, aligned in a row, and are brought into contact with the fixed position of the outer periphery of a guide roller 19. The guide roller 19 is rotated in an arrow direction, and the work (a) moves in the cross direction of a conveyer 1 along its outer periphery and is released. As a result, fixed interval is generated between the works (a), and the works are aligned and conveyed. The time of the guide roller's restraining the work (a) is also made uniform.

Title: Lateral type semiconductor device
Inventor: ARAKAWA HIDETOSHI
IPC: H01L29/72

Abstract: PURPOSE:To obtain a high current amplification factor and to improve the integration of a semiconductor device by forming a high impurity buried layer formed inside a dielectric isolating insulating film near the periphery of an emitter region except a side opposed to a collector region, thereby improving a carrier transfer efficiency. CONSTITUTION:An N<+> type buried layer 12 and a dielectric isolating oxidized film 11 are projected to the side of an island 6 as compared with a conventional example so that an interval between the outer periphery of a P type emiter 2 and the inner edge of the layer 12 is substantially uniform at the three sides except the side opposed to the collector 1 of the emitter 2. Accordingly, the distance between the adjacent two sides of the side opposed to the P type collector 1 of the emitter 2 and the layer 12 is largely reduced as compared with the conventional example. As the results, the current amplification factor can be increased without losing the withstand voltage.

Title: Groove width copying method
Inventor: SHIGEYOSHI MASAYUKI
IPC: B23K9/12
Filed: 1995-02-02
Abstract: PURPOSE: To obtain weaving width corresponding to root gap by detecting the minimum electric quantity during weaving in one direction and the electric quantity at weaving final end in one direction and detecting increase/decrease of root gap based on the difference of these electric quantities and the reference value. CONSTITUTION: When the mounting position of a work 9 is displaced in the up/down direction (extended direction of an electrode 8) and the electric quantity of weaving final end is changed in proportion with the wire extension of welding electrode 8, the minimum electric quantity during weaving is changed in proportion with the extended length of welding electrode 8 in the same way, thus, in the case a root gap G0 is constant, the difference between both electric quantities shows a fixed value. Accordingly, by detecting the increase/decrease of root gap G2 based on the difference of both electric quantities and the reference value, in the case the mounting position of work 9 is changed in the up/ down direction, the groove width copying is executed with the weaving width W corresponding to the root gap G2.

Title: Image forming device

Filed: 1998-02-23
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device which outputs a satisfactory image even in the use of a photoreceptive, pressure-sensitive record medium that is slow to change with a humidity change. SOLUTION: By using a humidity sensor 27, whose detection value changes almost at the same speed as the humidity of the photoreceptive part of a photoreceptive, pressure-sensitive record medium changes with ambient humidity, the detection value by the humidity sensor 27 is almost equal to the value of the humidity of the photoreceptive part of the photoreceptive, pressure- sensitive record medium at the time of image formation (at the present moment). Therefore, even in the use of the photoreceptive, pressure-sensitive record medium whose characteristic is changing due to the humidity, conditions for the output of a satisfactory image can easily be computed by a controller 50.
