Abstract: PURPOSE:To provide a high-sensitivity DC current sensor whose structure is' comparatively simple and whose detection capability) is excellent with reference to a change in an especially minute current in a DC leak breaker or the like. CONSTITUTION:This sensor is constituted in such a way that detection coils 3a, 3b are wound respectively in a toroidal shape on opposite side faces on a detection core 2 composed of a ring shaped soft; magnetic material, that a plurality of through holes 4 are made in opposite side faces other than them of the detection core 2 and that exciting coils 5a, 5b are wound. When a DC current I flows to a conductor 1, to be detected, which is arranged so as to be passed through the inside of the detection core 2, a magnetic flux PHI0 generated inside the detection core 2 and a magnetic flux PHI2 on the basis of an AC current flowing in the exciting coils 5a, 5b cut off a magnetic path formed in the circumferential direction of the detection coil 2 due to their mutual repulsive action. When the magnetic flux PHI0 is changed (ON-OFF) in terms of time by a magnetic switch which forms a magnetic gap periodically, an electromovite force is generated in the detection coils 3a, 3b, and a change in a minute current is detected.

Title: Manufacture of portable container
Inventor: TATEBAYASHI AKINOBU
IPC: B29C33/00
Filed: 1986-09-18
Abstract: PURPOSE:To make it possible to integrally connect an injection-molded item at the predetermined position of an elastic member to be connected, the wall thickness of which changes, by a method wherein the elastic member to be connected is pressingly arranged so as to leave the predetermined cavity space within an injection mold and, after that, thermoplastic resin is filled in said cavity space in order to integrally mold the injection-molded item together with the elastic member. CONSTITUTION:Thermoplastic resin melted with an injection molder is poured and filled through a sprue 5 to a cavity space 3. In this case, an elastic member to be connected 4 is pressed between the urging parts 11 and 12 of both molding tool parts 1 and 2 and the sealing function of the urging parts completely prevent the efflux of the molten resin out of the cavity space 3 from occurring. The molten resin solidifies in the cavity space 3 so as to cover and bond the outer end edge 41 and neighborhood 42 of the elastic member to be connected 4. The preferable bonding of the resin to the member is done by melting the bonding part of the elastic member to be connected 4 by the heat of the molten resin so as to bond the resin to the member in such a manner that the resin embraces the elastic member to be connected 4. Thus, the resin is integrally molded by injection molding at the predetermined position of the elastic member to be connected 4 so as to manufacture both outer edges of the main body and/or the lid of a portable container.

Title: Coating method for optical fiber
Inventor: MIKI MASAJI
IPC: C03C25/10
Filed: 1985-10-04
Abstract: PURPOSE:To coat an optical fiber with a thermosetting resin in such a manner as to have good strippability of the coating in the stage of connecting the optical fibers and to eliminate the possibility of flawing the optical fiber by uniformly coating the thermosetting resin in a half polymerized state then curing the resin thereby sticking the resin to the fiber. CONSTITUTION:The optical fiber 2 is introduced into a vessel 6 for a coating material right after spinning from an optical fiber base material 1 and the thermosetting resin 5 is uniformly coated in the half polymerized state on the outside peripheral surface of the fiber 2. The fiber is then introduced into a curing furnace 9 where the fiber is heated to cure and stick the resin 5 coated thereon. The fiber 2 is thus coated. The resin 5 itself is first bound with the fiber in the half polymerized state according to the above-mentioned method; therefore, the adhesive power to the fiber 2 is weak and the resin covers the fiber 2 in the form of a sleeve. The strippability of the fiber is consequently good and the possibility of flawing the fiber 2 in the stage of connecting the same is eliminated.

In the image forming zone, a rotating photoreceptor is irradiated with light from a LED head through a light-transmitting supporting side for image exposure to produce holes and electrons in the inside of a photocarrier exciting layer. When positive bias voltage is applied on a developing device, electrons move to the surface side of the carrier transfer layer by the bias voltage and are compensated with the positive charge on the edge of a magnetic brush to deposit the toner on the surface of the photoreceptor.  Further, the toner is transferred to a recording paper by a transfer roller and then fixed.

Title: Fabrication of thin film semiconductor device
Inventor: URAZONO TAKENOBU
IPC: H01L21/20
Filed: 1994-08-24
Abstract: PURPOSE: To eliminate the need of a laser antireflection film on an existing semiconductor thin film by radiating the laser beam from the rear surface side of a transparent insulating substrate. CONSTITUTION: The transparent insulating substrate 1 is irradiated with a laser beam having adequate energy from the rear side of a transparent insulating substrate 1 to crystallize a semiconductor thin film 2 and activate impurity. Since the gate electrode G is exposed in direct to the laser beam from the rear side in this processing, crystallization can be enabled. Since radiation of laser beam is performed from the rear side, the transparent insulating substrate 1 must be selected from the materials which do not absorb the laser beam. To limit the reflection at the rear side, it is preferable to determine the thickness of the transparent insulating substrate 1 in accordance with wavelength of the laser beam, which eliminates the need of a conventional antireflection coating on the semiconductor film.
