Patent JP-H03147220-A (JP)
Title: Grounding switch
Inventor: TAKAHASHI YUJI
IPC: H01H33/64
Filed: 1989-11-02
Abstract: PURPOSE:To perform induction current switching with a small driving force and a simple structure by providing at least one of the circumferences of a movable side electrode and a fixed side electrode with a magnetic body constituted in an approximately cylindrical form. CONSTITUTION:By disposing a magnetic body 20 around a movable side electrode 4, current may be shut off near the zero current point. Namely, while the magnetic body 20 does not show an inductance until the zero current point as it is in a saturated condition, the magnetic body shows a great inductance component when it goes beyond the zero current point, and the current is reversed to release the saturated condition, and the magnetic body 20 tends to maintain the zero current condition. Near the zero current point, the voltage applied to the magnetic body 20 is an electromagnetic induction current of several kV to several tens kV. Also related to the voltage, little current flows between the electrodes of a grounding switch as long as the non-saturated condition of the magnetic body 20 continues, and no voltage is applied between the electrodes. Namely, sufficient time is allowed for an arc to disappear and gas to be cooled. As a result, current may be shut off quickly and securely.

Title: Reverse power flow suppressing circuit for electric power storage type emergency power unit
Inventor: FUJIKURA MASANOBU
IPC: H02J7/35
Filed: 1993-11-16
Abstract: PURPOSE:To prevent the reverse flow of electric power to a commercial power supply system side even though the electric power of a load decreases when a separately provided power supply system is operated at the maximum power in parallel with the commercial power supply system. CONSTITUTION:When the electric power detecting value W of an electric power detector 11 connected between a commercial power supply system 2 and load 4 becomes lower than the set value of a suppression commanding value setter 13, a comparator 12 outputs a suppression commanding signal P to an output control circuit 14. Upon inputting the signal P, the circuit 14 changes the output of a charging control circuit 8 so as to maintain the detecting value W at a prescribed level even when the electric power of the load 4 fluctuates by outputting a current commanding value C to the circuit 8. The circuit 14 is constituted in such a way that, when a suppression control relay is actuated by the signal P, an adder calculates the difference between the set value of an electric power setter and the detecting value W and a proportional-plus- integration adjuster inputs the calculated result of the adder and outputs a current command value C for adjusting the inputted difference to zero.

Title: Photosensitive printing body
Inventor: SAKAI ATSUSHI
IPC: G03F7/00
Filed: 1992-10-23
Abstract: PURPOSE:To obtain a photosensitive printing body for producing a porous pressplate with reduced processes without using a mold and corresponding to a multikind and small lot production by a method wherein the photosensitive printing body is so composed that a photosensitive layer containing a photosensitive substance and a filler is held on a porous substrate. CONSTITUTION:When a light-transmitting original 6 is overlapped on a photosensitive printing body 1 and exposed to a light, the light is transmitted through a transparent part of the original 6 to reach a photosensitive layer 5 held on a porous substrate 2. In the exposed part of the photosensitive layer 5, an occurrence of a photo-setting reaction results in the higher hardness of a photosensitive substance 3 and a larger force of binding a filler 4, and a sparing solubility in a specific solvent is obtained. On the other hand, the photosensitive layer 5 corresponding to an opaque part remains easily soluble in the specific solvent without an occurrence of a photo-setting reaction and an increase of the force of binding the filler 4. When the surface of the photosensitive layer 5 is washed by the specific solvent after being exposed to the light, the exposed part is not dissolved, but the unexposed part is dissolved to be removed. Thus, the photosensitive printing body 1 has a structure having projected parts.

Title: Electrically insulating collar for fastening rail, and injection mold therefor
Inventor: KAMA KUNIICHIROU
IPC: B29K77/00
Filed: 1993-10-22
Abstract: PURPOSE:To improve the durability of an insulating collar, by a method wherein a resinous material consisting of nylon 66 in which glass staple fibers are mingled is injection-molded with a mold having either a plurality of gates, which are on a plane intersecting perpendicularly to the central axis of the boss part of the insulating collar, are near the boss part and are almost at regular intervals, or a continuous gate. CONSTITUTION:When a resinous material, i.e., a resin, consisting of nylon 66 in which glass staple fibers are mingled is injected at a fixed pressure through a sprue 64, the head of resin-flow is led into the sprue 41, and sludge and the like are carried away and are pushed into a sludge well 68. After that, the resin not including the sludge is led into runners 66 and is filled into a runner lock part 70, following which the resin is led into a cavity 72 through pin point gates 74. At this time, after the resin-flow is filled into the boss part of an insulating collar, the resin is allowed to flow radially from the inner peripheral side of a flange part toward the outer peripheral side thereof. The head of the resin-flow flows toward the periphery of the flange part, and the resin cooled and the sludge concentrates on the surface of the periphery. Therefore, a weld line is not produced on the surface of the insulating collar.
