Title: Switching circuit
Inventor: WATANABE YUKIO
IPC: H02M7/48
Filed: 1977-09-27
Abstract: PURPOSE: To provide the subject circuit wherein a saturable reactor is provided in a current path connecting a semiconductor element carrying out switching to a load, thereby to suppress the short-circuiting current at the storage carrier of diode and to reduce the switching loss.  
     CONSTITUTION: Upon rendering a transistor 12 into a conductive state, a current flows through a DC motor 15 which is a load through a saturable reactor 28 and a reactor 14, and the voltage of a source 11 is retained only by a product of voltage and time determined by the characteristic of the saturable reactor 28, and the saturable reactor is in saturated state, that is, in set state. Upon rendering the transistor 12 into a non-conductive state, the saturable reactor 28 is excited in the inverse direction by a current flowing through diode 13 by the storage energy of the reactor 14 and DC motor 15, and is in saturated state, that is, in reset state. By repeating such operations, the source short ciucuit current generated by the storage carrier of a feedback diode can be fully suppressed, and at the same time the switching loss can be reduced

Title: Manufacture of chip-type electronic component
Inventor: KIMURA RYO
IPC: H01C1/148
Filed: 1995-05-15
Abstract: PURPOSE: To share a common terminal electrode structure among various chip- type electronic components to obtain a method for continuously manufacturing chip-type electronic component, excellent in electrical characteristics, at low cost, and provide various chip-type electronic components having high adhesion and solderability as terminal electrodes. CONSTITUTION: A chip component carrier is formed by continuously forming holding areas 8 for holding a chip component 10 in a band-shaped substrate 7 at specified intervals. Chip components 10 are inserted into the carrier. While the carrier is continuously or intermittently conveyed, a solder layer is formed on a base electrode, which is formed on both the ends of each chip component 10 by applying conductive resin paste, by complex reaction between organic acid lead and metallic tin.

Title: Directional antenna
Inventor: ISHIKAWA KAZUNORI
IPC: H01Q19/10
Filed: 1977-09-27
Abstract: PURPOSE:To improve the composite directivity on horizontal plane by providing a sub-passive reflector between the radiator and passive reflector of a directional antenna and by compensating the phases difference generated due to the arrangement of the directional antenna by its own advance phase difference. CONSTITUTION:Sub-passive reflector 6 is provided between passive reflector 1 and radiator 2 and its reflection face 7 is provided to the nearly middle position between plate 1 and radiator 2. Owing to reflection and diffraction effects of this sub-passive reflector 6, phase directivity becomes advanced and the composition can be done in phase in the direction in which a fall occurs, thereby improving the fall level. The bigger the diffraction of sub reflector 6 is, the higher the frequency is, so that the advance phase difference will become bigger and correspond to the frequency variation of the phase difference due to the antenna arrangement. As a result, the variation of frequency characteristics at a fall level becomes small since the composition can be done in phase in the fall direction.

Title: Cutting device
Inventor: MURAI YASUSHI
IPC: B26D1/10
Filed: 1998-04-13
Abstract: PROBLEM TO BE SOLVED: To conduct a half cut with a simple structure and without enlarging the whole device. SOLUTION: A moving roller 12 for half-cutting, a moving roller 13 for full-cutting, and a position regulating roller 14 are mounted on a slide shaft 10 so that the two of the moving rollers 12, 13 for half-cutting and full-cutting may be switched with a control lever 15. By moving roller 12 for half-cutting along above the cutter blade 5 through the position regulating roller 14 while maintaining a prescribed position distant from the cutting edge of a cutter blade 5 paper 1 can be half-cut. By moving the moving roller 13 for full-cutting into contact with the cutting edge of the cutter blade 5 and moving it, the paper 1 can be full-cut.  Even the large width of the paper 1 does not require applying a heavy load to the whole cutter blade 5 like a conventional press- cutting method, thus it is possible to downsize the whole device with a simple structure, and conduct two ways of cutting; half-cutting and full-cutting.

IPC: B65H1/26
Filed: 1993-04-21
Abstract: PURPOSE:To use a sheet feeder in a free shape in accordance with a setting up area by forming the sheet feeder so that it can be turned with a hinge part serving as the center. CONSTITUTION:A sheet feeder can be manually bent in almost a right angle direction relating to a feeder main unit, at which time, extend an accordion- shaped cover 6 and curve a sheet guide member 5 in accordance with a turning angle of the sheet feeder. When recording is started in this condition, a sheet P, delivered by a feed roller 3 and guided by the sheet guide member 5 to between upper/lower guide plates 4a, 4b, can be conveyed to a pair of resist rollers 9 of the feeder main unit. Since the sheet feeder can be thus used in a folded condition, in a site of narrow setting space, the feeder can be suppressed from protruding in the lengthwise direction, to prevent the feeder from being hooked by a user and tumbled to be damaged, and safety can be improved.
