Patent JP-S6097718-A (JP)
Title: Switch circuit
Inventor: TOKUNAGA KIICHI
IPC: H03K17/10
Filed: 1983-11-02
Abstract: PURPOSE:To turn on or off stably a switch at a wide load region by connecting a circuit using an MOSFET between an anode and a gate of a GTO so as to supply a gate current required for the GTO from a load current via the MOSFET. CONSTITUTION:When an ON-signal is fed to a drive circuit and a GTO11 is turned by an on-gate signal, an electric charge of a capacitor 32 flows via a gate and a source of an MOSFET22 and a gate and a cathode of a GTO12. When a positive voltage is impressed to the gate and source of the MOSFET22 and it is turned on, the GTO12 is turned on and the other elements are turned on similarly. When a load current is a holding current or over of the GTO, the on-state is continued by the GTO only until an off-gate signal is impressed to the GTO11. Since MOSFETs 23-2n are brought into on-state, when the load current does not reach the holding current of the GTO, the gate current of GTO12-1n required via the MOSFETs 22-2n flows and the on-state is continued.

IPC: F16N31/00
Filed: 1983-11-02
Abstract: PURPOSE:To make the discharge of oil smooth from a rotary machine, in which a bearing subjected to forced lubrication is provided, and prevent oil spray from jetting out of the air vent of a casing or a couppling cover by forming either of a main shaft oil-discharge pipe or an auxiliary oil-discharge pipe in U-shaped piping. CONSTITUTION:An auxiliary oil-discharge pipe 20 is connected to an auxiliary oil-discharge chamber 6a, and is provided with a U-seal part 20a related to U- piping. And, oil-discharged through the auxiliary oil-discharge pipe 20 is gradually accumulated in the U-seal part 20a, up to a height H and, when the quantity of discharged oil is further increased exceeding the height H, the exceeding quantity of oil is discharged into a discharged-oil collecting pipe 9. Thereby, a head corresponding to the height H of the U-seal part 20a is always retained by the auxiliary oil-discharge pipe 20, eliminating the flow of air due to connection to a main oil-discharge pipe 7.

IPC: G01R33/381
Filed: 1984-09-29
Abstract: PURPOSE:To obtain the uniform magnetic field of a sole coil and to eliminate the difficulty of manufacturing steps by winding a superconductive wire to gradually increase the outer diameter at both axial ends from the axial center. CONSTITUTION:A superconductive magnet magnetic gradually increases the number of turns of a superconductive wire 2 from the center toward both ends to provide the secondary curvature axially on the outer peripheral surface of a cylindrical superconductive coil 1. The coil 1 is formed by two ways of double pancake winding and solenoid winding methods. Since the numbers of windings at both ends of the coil 1 to originally weaken a magnetic fields is more than that at the center, a uniform magnetic field can be obtained at the center of the coil 1. Thus, a coil burning loss at quenching time of specific problem of the case that two coils are used can be completely avoided, the shapes of the winding shaft and the bobbin can be not necessarily formed specially, and no particular difficulty arises in the winding step.

IPC: H01S3/093
Filed: 1983-11-01
Abstract: PURPOSE:To contrive to equalize the values of gains in the cross sections of the laser active materials in the title laser by a method wherein reflective surfaces, which have been formed without changing the mean shapes thereof and have been cut circular-arc-shaped grooves therein, are used instead of mirror finished reflective surfaces for the laser. CONSTITUTION:In case of the light of direct lights 7 emitted from flash-lamps 2 on the cross section of a reflecting cylinder 3 and the light of reflected lights 8a and 8b reflected at circular-arc-shaped groove-cut reflective surfaces 4a, the light, which was emitted from the flash-lamps 2 and reached the circular-arc-shaped groove-cut reflective surfaces 4a, is divided into the lights 8a, which are reflected at recessed places in the circular-arc-shaped grooves, and the lights 8b, which are reflected at protruded places in the circular-arc-shaped grooves, because there are a little deeper recessed places and a little higher protruded places than the bielliptic surfaces in the circular-arc-shaped grooves. These reflected lights 8a and 8b result in respectively inciding in each different places of laser active materials 1, because the directions, in which the reflected lights 8a and 8b are reflected, are different from each other. As a result, the reflected lights 8a and 8b emitted from the flashlamps 2 produce an effect that the laser active materials 1 are equally irradiated, and an effect of equalization, that the values of gains in the cross sections of the laser active materials 1 become equal even in its central parts and even at the peripheries.

Filed: 1990-07-31
Abstract: PURPOSE:To move a locus at a high speed by holding the output speed of a acceleration/deceleration part which supplies the actual travel speed of the locus at a time when it goes less than the command speed of the next execution block. CONSTITUTION:A speed signal generating part 2, when route length Lm and a speed command value Fm read out by a buffer readout part 31 are set, divides the route length Lm into the amount of travel Fm.DELTAT at every sampling inter ruption with cycle of DELTAT, and outputs it as a speed signal V. An acceleration/ deceleration processing part 32 is operated as a filter which smooths the speed signal V of rectangular wave shape outputted from the speed signal generating part 16 in an ordinary operation similarly as in a conventional system, and a smoothing speed signal (v) is outputted. A speed comparison part 30 compares the smoothing speed signal (v) with the command speed Fm+1.DELTAT of the next block outputted from the buffer readout part 31, and sends a holding signal to the acceleration/deceleration processing part 32 when it is v<Fm+1.DELTAT. The acceleration/deceleration processing part 32 interrupts deceleration in the case of receiving the signal while performing the deceleration, and holds and outputs the output value (v) last time as it is.

Filed: 1984-10-03
Abstract: PURPOSE:To recover gaseous hydrogen efficiently, to prevent danger of explosion, etc., and to facilitate storage, transportation, and reutilization by introducing gas contg.

CONSTITUTION:A gaseous mixture from a generating source 10 is fed through a three way valve 12 and a valve 14 to one of a vessel 16 packed with a hydrogen storage alloy, and the hydrogen storage alloy in the vessel is held at a fixed temp. where the equilibrium pressure at the temp. is below the pressure of hydrogen to be recovered. In this stage, neither gaseous mixture nor cooling water are supplied to another vessel packed with hydrogen storage alloy. The gaseous H2 in the gaseous mixture is absorbed by the hydrogen storage alloy in the form of metal hydride. After a specified amt. of gaseous mixture is fed to the vessel, the valve 14 is closed, and the three-way valve 12 is changed over, and a valve 20 is opened to introduce the gaseous mixture into the other vessel 22 packed with hydrogen storage alloy. Further, the three-way valve 28 is changed over to a three-way valve 30, and cooling water is fed to the vessel 22. By these series of changing over operations, gaseous H2 can be recovered continuously. When the concn. of H2 reaches a specified value, the valve 18 is closed, and the vessel 16 is detached as it is combined with the valve 14 and 18 in one body, and a fresh vessel 16 is installed to replace the detached vessel.
