Patent JP-S58220470-A (JP)
Title: Semiconductor device
Inventor: SHIGEKANE TOSHIO
IPC: H01L29/72
Filed: 1982-06-16
Abstract: PURPOSE:To prevent the increase in a base current by connecting a resistor and the main electrode of an FET in series between the base and the emitter of a transistor, connecting the gate of the FET to the base and turning ON the FET when the emitter junction is forwardly biased. CONSTITUTION:When a current flows from the base B of an NPN type element 1 to an emitter E, an enhancement type NchFET 6 which is connected to the B is applied with a voltage at the gate and turned ON, and a resistor 3 is inserted between the B and E of the element 1. On the other hand, when a positive voltage is applied to the emitter E and a negative voltage is applied to the collector C, the FET 6 is turned OFF to block a current from the E to the B via the resistor 3. Accordingly, the parasitic effect of the transistor 1 is not produced, and the increase of the reverse recovery time can be prevented. In this case, a reverse voltage is applied to the junction of the N type source of the NchFET and a P type substrate, but the value is forward voltage of a flywheel diode 2. Accordingly, it can endure sufficiently against the withstand voltage between the gate and the source. In this manner, the increase in the base current can be prevented with a simple circuit configuration, and is effective for a PWM type motor control or the like.

Inventor: YASUDA TOSHIHIRO
IPC: G21C13/00
Filed: 1996-03-30
Abstract: PROBLEM TO BE SOLVED: To make it possible to improve workability and work accurately and efficiently while reducing workers' exposure doses to radiation significantly by shielding radiation doses efficiently. SOLUTION: When installed in a reactor pressure vessel 1, a new core shroud 20 is hoisted together with a radiation shield 23 and a seal tank 24, with the reactor pressure vessel 1 filled with the water, and is set above a shroud support 3. Thereafter, the water is drained from the vessel 1 and the new core shroud 20 is seal-welded onto the shroud support 3 from the outer periphery. Subsequently, a working area 51 is formed in the shroud 20 by pouring the water into a downcomer part 10 and a tank 24. After the shroud 20 is seal-welded onto the shroud support 3 from the inner periphery, the radiation shield 2 and a seal tank 24 are removed by lifting them with the vessel 1 filled with the water.

Title: Vibration control device
Inventor: NISHINAKA AKIRA
IPC: F04B39/00
Filed: 1990-04-19
Abstract: PURPOSE:To reduce vibration transferred to the floor from a vibrator by controlling current energizing the coil of a magnetic cylinder while being synchronized with the displacement of the vibrator. CONSTITUTION:The vertical movement of a permanent magnet 8 which is vibrated monolithically with a compressor 19 acting as a vibrator, is detected by a sensor coil 7 as current signals. The detected signals are amplified by a power supply 14 so as to be supplied to a main coil 6 fixed on the floor plate 16, so that force is imparted to the permanent magnet 8 from the main coil 6 while the main coil is being synchronized. Since the compressor is indirectly supported by the electomagnetic force of the immovable main coil 6 fixed on the floor plate 16, vibration transferred to the floor plate can thereby be reduced to a great extent as compared with passive vibration prevention means such as single rubber or springs which is formerly used.

Then, the processor 2 gets the use right of an information bus 2 and executes dedicated instructions 1 to 4 in accordance with the address X1. Thus, dedicated instructions are directly read out without passing the processor 1.

Abstract: PROBLEM TO BE SOLVED: To improve the workability in a manufacturing process and to achieve higher physical properties by forming an FRP pipe by winding up flat yarn consisting of reinforcing fiber multifilament yarns having specific yarn width and a yarn width/yarn thickness ratio of a specific value or more. SOLUTION: Flat yarn 3 consisting of reinforcing fiber multifilament yarns is helically wound around the flexible tube core material 2 applied to a mandrel 1 at an angle of ±30 deg. with respect to the axial direction of the mandrel by a filament winding method (winding layer 4). Next, a helical winding layer 5 is provided at a winding angle of ±10 deg. and a helical winding layer 6 is further provided at a winding angle of 30 deg. to form a preform 7 consisting of a plurality of fat yarn winding layers. This flat yarn has yarn width of 4-30mm and a yarn width/yarn thickness ratio of 10 or more. When yarn width is below 4mm, flattening effect is reduced and, when yarn width exceeds 30mm, handling is difficult and, when the yarn width/yarn thickness ratio is below 10, it is difficult to suppress crimps small.  Yarn width is about 4-16mm from an aspect of easiness to handle.

SOLUTION: At first, an unwoven sheet S is pressed down by a rod part 11 of a guide 1 and the topmost unwoven sheet S1 is sucked by a suction cup 22. When the unwoven sheet S1 is raised to a prescribed height, a suction device 2 is swung as it is. A clearance between a first unwoven sheet S1 and a second unwoven sheet S2 is gradually enlarged. Repeating the action, the clearance reaches the ends of the unwoven sheets S1, S2, and at the same time the sucked second unwoven sheet is cut off. Therefore, only the unwoven sheet S1 stacked on the topmost is remained on the suction device 2. On the other hand, the cut-off second unwoven sheet S2 falls and returns on the stacked unwoven sheets S.

Title: Lighting load controlling device
Inventor: SAKO HIROYUKI
IPC: H05B41/392
Filed: 1989-04-25
Abstract: PURPOSE:To change light output almost linearly to linear adjustment of a dim signal by providing a means to compensate the light output of a lighting load to change it in proportion to the change of parameters of the dim signal. CONSTITUTION:A high frequency converting circuit 1 converts a DC voltage obtained from a DC power source E1 into a high frequency voltage and applies it to a lighting load 2 through a resonance circuit 6, and a control circuit 3 controls the action of the high frequency converting circuit 1 to change the light output of the lighting load 2 continuously. A dim circuit 4 generates a dim signal for setting a light output of the lighting load 2, and a compensation circuit 5 compensates the dimming signal and gives it to the control circuit 3. The dimming circuit 4 outputs a dimming signal voltage Vb changing in proportion to the change of a resistance value of a dimming resistor VR, and the compensation circuit 5 compensates this dimming signal voltage Vb and converts it into a control signal voltage Vc for changing the output of the lighting load 2 in proportion to the change of the resistance value of the dim resistor VR. The light output can thus be changed almost linearly to linear adjustment of the dimming signal.
