Title: Bending working method of welded steel pipe
Inventor: SAKAGUCHI ICHIROU
IPC: B21D7/16
Filed: 1978-09-29
Abstract: PURPOSE: To control a decline of low temperature quality of the welded part after hot bending working, by carrying out bending working, maintaining the welded part temperature in the welding steel pipe which is being heated, to a lower temperature than that of the base metal part.  
     CONSTITUTION: The circular part which opposes the inner circumferential face of the coil 2 of the welded steel pipe P is evenly heated to 900W1000°C including the base metal part P 1  and the welded part P 2 , by connecting the high frequency power supply 21 to the heating coil 2 and feeding the high frequency current. While the aforesaid heating is being made, the temperature of the welded part P 2  is maintained to a lower temperature than that of the base metal part P 1  by 100W150°C, by blowing a cool wind from the nozzle of the cooling air pipe 7. When the driving gear 3 is operated and the steel pipe P is pushed out forward by the tail stock 4, the steel pipe P is moved, gradually being bent by the circular part of narrow width which is being heated with the coil 2, the heating position to the bending part B is gradually varied from the tip side of the bending part B to the rear side, and the steel pipe P is continuously bent between the guide rolls 1, 1 and the clamp jig 6.

Title: Optical gate element and two-dimensional optical gate array
Inventor: MORI YOSHIHIRO
IPC: G02F1/313
Filed: 1989-05-15
Abstract: PURPOSE:To perform quick switching of high gain by providing a high- reflectivity multilayered thin film layer and a low-reflectivity dielectric layer and allowing an active layer to have a gain to an optical signal at the time of forward current flow to the active area and allowing it to have a loss at the time of non-flow. CONSTITUTION:When a current is supplied from a power source, holes and electrons are collected in an active layer 107; and when the gain due to induced emission is in the same degree as the loss, an incident optical signal 101 is not attenuated and is reflected by a DBR layer 105 to output an emitted optical signal 104. When the current is increased, the gain of the active layer 107 exceeds the loss, and the incident optical signal 101 is amplified and is reflected by the DBR layer 105 and is amplified again to output the emitted optical signal 104. When the current is not supplied, the incident optical signal 101 is attenuated to disappear by the loss of the active layer 107, and the emitted optical signal 104 is not outputted. Consequently, the switching speed is deter mined by turning-on/off of the current. Thus, quick switching is possible and the gain of the optical signal is increase about twice.

Abstract: PURPOSE:To perform reasonable head cleaning by which no damage than it is needed is given on a head by monitoring the absolute value of the output of a reproducing signal by always detecting the reproducing signal even in recording, and cleaning the head by operating a head cleaning mechanism. CONSTITUTION:In a time plus VTR, etc., the recording is performed with two recording heads, and simultaneously, the reproducing signal is taken out from a part recorded just before on a magnetic tape by using a nonuse head, and the absolute value of the signal is always continued to read. When the (blinding) phenomenon of the head occurs, the absolute value of the output of the reproducing signal is lowered, therefore, when the absolute value becomes less than a preset value, a power is supplied to a solenoid 6 for a constant time. Thereby, the solenoid 6 is operated, and a rotary roller 2A is pressed on the rotary head part of a rotary drum 1 for an energized time, and the cleaning of the head is performed. Furthermore, such operation is repeated by detecting the reproducing signal until the absolute value goes over the preset value when a few quantity of reproducing signals exists. In such a way, stable recording can be continued.

Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To prevent electrical conduction failures caused by deteriorated contacts and increased contact resistance due to an increased number of keyings. SOLUTION: A current generated in a current generating circuit 103 is passed through a coil A102 attached to a key cap 101 to set up a magnetic field by electromagnetic induction. When the key cap 101 is depressed to come closer to a coil B104 formed on a key bottom part, the magnetic field set up by the coil A102 causes an electromotive force to be generated in the coil B104 by electromagnetic induction, Then, a current generated in the coil B104 is detected by a current detection circuit 105 installed in the exterior, and thus the depression of this key switch can be detected, When the key switch returns to its original position, the electromotive force in the coil B104 is eliminated, and thus it can be decided that the key switch is not in a depressed state.
