Title: Additional circuit of semiconductor valve
Inventor: HANSU RAABAA
IPC: H03K17/0814
Filed: 1990-01-22
Abstract: PURPOSE: To limit an overvoltage which can occur when a reverse current is abruptly broken by providing an additional circuit for gate turning-off thyristor having auxiliary branch paths which are connected in parallel with diodes and have auxiliary capacitors. CONSTITUTION: Auxiliary branch paths which contains auxiliary capacitors Cd and are connected in parallel with diodes Ds are added to an additional circuit. In order to maintain the inductances of the auxiliary branch paths as low as possible, the capacitors Cd are directly connected in parallel with the diodes Ds and spatially arranged near the diodes Ds as close as possible. When a gate is turned off, a saturation reactor Lk becomes an unsaturated state through a resistor Rk connected in parallel with the reactor Lk and, when the reactor Lk becomes the unsaturated state, the resistor Rk limits a reverse current to a fixed value, namely, further drops an overvoltage.

Abstract: PURPOSE: To prevent the induction of a disconnection by etching and relieving the difference in level of an oxidized film between the surfaces of an element region and an isolating region in a semiconductor substrate.  
     CONSTITUTION: An n +  buried layer 12 followed by an n epitaxial layer 13 are piled on a p -  Si substrate 11, and the layers are covered by a SiO 2  film 14. Masks 16a, 16b of Si 3 N 4  film are applied to the layer above so as to eatch the film 14 and n layer 13 successively and form a concave portion 17. Next if a separated oxidized layer 18 is made through wet oxidization at 1000°C, 9 air pressure and for 60min., thin oxidized films 20a, 20b are produced on the rugged portion 19 and the masks. Excepting the Si 3 N 4  film 16a and the SiO 2  layer 14 under that 16a, the remaining one is exposed to a POCl 3  gas at a high temperature in order to form a PSG layer on the film 18, then an n +  layer 21, using the diffusion of P. The film 20b is changed into PSG at the same time. Next the film 20b is etched to the extent beyond its thickness so that the PSG on the isolated layer 18 as well as the rugged portion are removed.

Title: Sheet cassette, sheet carrier and image forming device
Inventor: KUBOTA TAKESHI
IPC: B65H5/38
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To carry a sheet under an optimal condition according to the thickness of the sheet by constituting a sheet cassette such that a carrier guide is moved so as to have different sheet carrying lengths between one side and its opposite side in a sheet width direction. SOLUTION: The circular arc part of a guide plate 10b is moved to the position of a solid line and the position of a broken line and when a sheet having a normal thickness is to be carried, the circular arc surface of the guide plate 10b is set so as to form the same surface with a carrier roller. When a thick sheet is to be carried, a lever 10b1 is operated and the circular arc surface of the guide plate 10B in a side opposite to the side of a reference guide is moved up to the carrier roller (thick paper mode). Thus, since the carrying length of a sheet width likely to be delayed, when the thick sheet is U-turn carried, of a side opposite to the side of the reference guide is short, delaying is prevented and sheets are carried to an image transfer section while tips thereof are aligned in the width direction.

Title: Closed valve state holding device for emergency shutoff valve
Inventor: MURAKAMI MOTOAKI
IPC: F16K31/12
Filed: 1999-01-22
Abstract: PROBLEM TO BE SOLVED: To provide a closed valve state holding device for an emergency shutoff valve through which water soiled by a foreign matter mixed at the time of repairing a damaged point, etc., never enters a reservoir tank by mistake even when an abnormal situation of damage, etc., takes place upstream from a setting position of the emergency shutoff valve on a distributing main pipe. SOLUTION: A closed valve state of a valve body 14 is detected by switching on a limit switch 26, and this valve closed state detection signal is input to a control means 27. The control means 27 outputs a valve closing signal to a closed valve state holding valve 25 in accordance with input of the valve closed state detection signal and closes the relative closed valve state holding valve 25. Consequently, even when hydraulic pressure of a distributing main pipe 1 recovers to a value exceeding a working set value after completion of repair of the damaged point of the distribution main pipe 1, this pressure never works on a piston 14A in a pressure chamber 16 as pilot pressure. Consequently, it is possible to hold the closed valve state of the valve body 14.

IPC: B29L7/00
Filed: 1988-01-25
Abstract: PURPOSE:To improve operational stability at the time of manufacture of a biaxially stretched film, by a method whrrein an unstretched film mainly comprised of polyethylene terephthalate is made the biaxially stretched film by stretching the same in a lateral and longitudinal directions in order, restretched in the longitudinal direction and thermal fixation is performed. CONSTITUTION:A substantially unstretched film mainly comprised of a polyethylene terephthalate is made a biaxially stretched film by stretching 2.5-5.0times in a lateral and longitudinal directions in order at a temperature of 80-130 deg.C, restretched 1.05-2.0times in the longitudinal direction at the temperature of 100-180 deg.C and thermal fixation is performed at 160-240 deg.C. When the temperature of the lateral/longitudinal stretching is less than 80 deg.C necessary stress for the orientation is increased drastically and the film is broken. On the contrary when the temperature exceeds 130 deg.C, the film is broken according to crystallization to be generated at the time of preheating. When draw ratio in the lateral/longitudinal stretching is less than 2.5times, uniformity where a thickness is favorable is not obtained. When the same exceeds 5.0times, the necessary stress for the stretching is increased drastically and the film is broken.
