Title: Hot rolling method for partially joined part of steel strip
Inventor: HIRA TAKAAKI
IPC: B21B1/26
Filed: 1986-08-01
Abstract: PURPOSE:To prevent the decrease of the press welding strength in the joint part of steel strips by interrupting the supply of a lubricating material to the partially joined part transiently on the inlet side of a hot finishing mill at the time of partially joining the steel strips before the rolling mill and subjecting the steel strips to endless rolling continuously with the rolling mill. CONSTITUTION:The preceding steel strip and the succeeding steel strip are partially joined by a round bar 2 and are continuously rolled by rolls 3 at the time of rolling the steel strip 1 having a sheet thickness t0 to a sheet thickness t1 with the rolls 3 of the hot finishing mill. The supply of the hot lubricating agent is interrupted since the partially joined part 2 of the steel strip 1 arrives at least at the position of the circumferential length of the rolls 3 on the inlet side of the rolls 3 before the strip is bitten by the rolls 3. The lubricating oil sticking to the surfaces of the rolling rolls is burned and removed by the contact with the hot steel strip during the revolution of the rolls 3 and the joint part of the steel strips is brought into the rolled state without lubrication. The rolling is executed by supplying the hot lubricating agent again after the passage of the joint part. The decrease of the press welding strength of the joint part is thus overcome.

Title: Working tool for hot working cr steel
Inventor: SO MITSUHIKO
IPC: C23C30/00
Filed: 1988-07-19
Abstract: PURPOSE:To inhibit seizing and to prevent the occurrence of surface defects on a material to be worked or treated by forming a W-based build-up layer on the surface of a tool brought into contact with the material to be worked or treated. CONSTITUTION:A W-based build-up layer is formed on at least the surface of the base material of a hot working tool brought into contact with Cr steel as a material to be worked or treated. At least the surface layer of the build-up layer preferably contains >0-20vol.% NbC and >=60vol.%, in total, of W and NbC. Since the build-up layer formed on the tool has a small affinity for Cr and a high m.p., seizing is hardly caused, surface defects on the material to be worked are reduced and the soundness of the surface of the material can be improved. The service life of the tool can also be prolonged.

Title: Protecting circuit for field-effect transistor
Inventor: NOTO YASUO
IPC: H03K17/08
Filed: 1986-08-01
Abstract: PURPOSE:To absorb surge energy to below the dielectric strength of an FET by connecting a Zener diode and a diode which has the opposite polarity from the Zener diode in series between the drain and gate. CONSTITUTION:The series circuit of the Zener diode ZD1 and the diode D1 which has the opposite polarity from the Zener diode is provided between the drain and gate of the N channel FET. A voltage applied to the gate G of the diode D1 connected in series between the gate and drain of the FET operates not to be drawn to the drain D and when the FET is off, namely, when a control transistor TR is off, the Zener diode ZD1 feeds the surge energy applied to the FET back to the gate of the FET, thereby reducing the voltage between the drain and gate below a constant value. Consequently, the FET consumes the surge voltage and the gate is turned on before a voltage higher than the dielectric strength is applied, thereby lowering the surge voltage.

Title: Electrophotographic device
Inventor: SEII MASAHIRO
IPC: G03G21/14
Filed: 1990-07-06
Abstract: PURPOSE:To obtain pictures of a high picture quality even when full-color printing is performed with a small-sized fixing device by reducing the peripheral speed of an intermediate transferring body to almost equal to that of the fixing device after all color toner images corresponding to one page of a transfer sheet are completely transferred to the intermediate transferring body. CONSTITUTION:Four colors of toner images overlapped in color upon each other against an endless intermediate transferring belt 9 are carried in the rotating direction shown by the arrow. After the yellow toner to be transferred last onto the belt 9 is completely transferred by the amount corresponding to one page, a controlling means 14 reduces the peripheral speed of the belt 9 so that the speed of the belt 9 can become almost the same as that of a fixing device 17. Then a transfer sheet 16 fed from a paper feeding cassette 15 is passed between the belt 9 and transferring device 13 and the devices 13 and 17 successively make transferring and fixing operations. Thus a full color picture is outputted. Therefore, a picture of a high picture quality can be obtained in a full-color printing mode.

Title: Temperature compensated amplifier
Inventor: KITAMURA TAKESHI
IPC: H03F3/14
Filed: 1992-07-07
Abstract: PURPOSE:To keep a certain gain regardless of the change of the ambient temperature of an amplifier by connecting a thermosensitive element to the input terminal of an operational amplifier. CONSTITUTION:A temperature compensating circuit 13 is connected to a second gate G2 of a dual gate MOSPET 2. The temperature compensating circuit 13 consists of an operational amplifier 14, a dual gate MOSFET 15 as the thermosensitive element, and a bias circuit which applies a prescribed bias to them. If the ambient temperature of a temperature compensating amplifier 12 falls in this constitution, the gain of the dual port MOSFET 2 is raised, and the drain current of the dual gate MOSFET 15 is increased. As the result, the source potential rises, and therefore, the potential of an inverted input terminal 21 of an operational amplifier 14 rises. The output voltage of the operational amplifier 14 falls in accordance with this rise, and the potential of the second gate G2 of the dual gate MOSPET 2 is dropped and the gain is reduced, and therefore, the change of the gain of an amplifier 1 is suppressed.

Title: Turbine rotor
Inventor: ODAWARA MASACHIKA
IPC: F01D5/02
Filed: 1982-10-14
Abstract: PURPOSE:To prevent cracks generated at a key seat by stress corrosion and thereby have sure torque transmission by embodying coupling of a turbine rotor through a torque ring, which is arranged adjacent to a wheel and transmits the torque to the shaft. CONSTITUTION:Torque from a wheel 3 is transmitted to the shaft 1 by the frictional force owing to hot fitting. If the wheel is heated more quickly than the shaft and it has brought about looseness, the transmission is made to a torque ring bore key 13 through a torque ring key 10, which is arranged as in a single piece with a torque ring 8, and then over to the shaft. The centrifugal force with this torque ring is small because of its small outside diameter and weight and the suface pressure owing to hot fitting is also small, so that the stress in the tangential direction at the inner surface will become small to lead to low stress concentration, which is likely to arise at the torque ring bore key 11. Thereby the key seat is free from fear of generation of cracks owing to stress corrosion. Thus the number of parts used can be suppressed as well as problems around the key seat such as stress concentration solved.

Title: Manufacture of joint pipe
Inventor: SAKAMOTO TAKESHI
IPC: B29C65/08
Filed: 1982-10-13
Abstract: PURPOSE:To make easily a joint pipe of the type of snap fit, by forcing a metal joint auxiliary pipe into an opening at the end of a plastic pipe while ultrasonic wave are being applied. CONSTITUTION:A diametrally reduced attaching section 6 of the auxiliary pipe 2 is fitted to the upward end opening of the pipe main body 1 fixed to a jig, and is pressed by a tool horn 5. By this pressing, the anchoring flange section 4 is anchored to an opening periphery 7 of the pipe main body 1. Pressing is further carried out by the tool horn 5 so that the anchoring flange section 4 enlarges forcibly the pipe main body 1 and fits therein. In this case, when ultrsonic waves are applied to the tool horn 5, the ultrasonic waves are transmitted to the auxiliary pipe 2, and the anchoring flange section 4 causes the inner surface of the pipe main body 1 to be softened and fits to the pipe main body 1. Thus, a joint pipe that has no anchoring recess therein can be easily obtained.

Abstract: PURPOSE:To shorten a crystallizing time by using a Ge-Sb-Te ternary membrane as the recording material of a phase changeable type optical recording medium performing the recording, reproduction and erasure of data using the phase change between a noncrystalline state and a crystalline state and substituting a part of Ge with Si. CONSTITUTION:An optical disk medium 3 wherein the structural strain of a noncrystalline state is changed using the phase change between the noncrystalline state and a crystalline state and a crystallizing time is controlled by controlling driving force at the time of crystallization from the noncrystalline state is obtained. Herein, in order to change the structural strain of the noncrystalline state with respect to a Ge-Sb-Te ternary membrane, a part of Ge is substituted with Si being an element having properties near to those of Ge. When a very small amount of Si is added, Si is preferentially coordinated at the atom position occupied by Ge in the noncrystalline state and a crystal structure is partially disturbed from the difference between the atomic radii of Si and Ge and the strain accumulated in the noncrystalline structure becomes large. As a result, the driving force for crystallization becomes large and a crystallizing time can be shortened.
