Title: Bias circuit and power supply using the same
Inventor: ONISHI HIROYASU
IPC: H02M3/28
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To obtain a constant bias voltage, regardless of fluctuations in an input voltage or output load current, reduce loss and arbitrarily lower power consumption. SOLUTION: In a bias circuit 41, parallel circuits are constituted of a plurality of bias windings 42 and 43, and a switch circuit 46 placed in one of the parallel circuits is on/off-controlled by a voltage monitoring circuit 48. Specifically, when an input voltage is high or an output load current is large, the voltage induced in the bias windings is increased and the switch circuit 46 is therefore turned off to reduce the bias voltage. When the input voltage is low or the output load current is small, the voltage induced in the bias windings and the switch circuit 46 is therefore turned on to increase the supplied bias voltage. As a result, the bias voltage supplied to the PWM control circuit 40 is stabilized.

Title: Plastic optical fiber
Inventor: TAN MASAYUKI
IPC: C08F12/00
Filed: 1987-03-04
Abstract: PURPOSE:To improve the photoconductivity in the range from the visible radiation region to the near IR radiation region by forming the polymer core of the optical fiber with a specified copolymer. CONSTITUTION:When the polymer core of the optical fiber is formed with the copolymer of octafluorostyrene and octafluoromethyl methacrylate, the C-H bond in the molecular structure is fluorinated.

Title: Coagulation of polymer latex
Inventor: SUGIMORI TERUHIKO
IPC: C08C1/00
Filed: 1983-03-22
Abstract: PURPOSE:To obtain polymer powder or grains of excellent powder or grain properties from a polymer latex, by using a nozzle for latex coagulation comprising a base plate provided with a plurality of small tubes each having a specified gap and a specified length. CONSTITUTION:In coagulating a polymer latex, use is made of a nozzle for latex cogulation, comprising a base plate provided with a plurality of small tubes in such a manner that the gap between the tubes is at least 1mm. and the projection of the tube beyond the base plate is at least 3mm.. When the tubes protrude beyond the base plate by at least 3mm., their tips are to reach the laminar region outside the eddy region, and therefore the polymer latex extruded from these tips can be gently carried by the laminar flow of the coagulation solution and coagulated to form high-bulk density polymer powder or grains free of fine powder and coarse grains. If the gap between the tubes is as narrow as 1mm. or below, the flowing of the coagulation solution into the tubing becomes difficult, so that satisfactory coagulation becomes impossible in the area outside the periphery of the tubing. Therefore, the gap between the tubes must be at least 1mm..

Title: Optical fiber type humidity sensor
Inventor: KAMINAGA KENJI
IPC: G01N21/41
Filed: 1986-03-05
Abstract: PURPOSE:To enable measurement which is high in stability and accuracy and widely applicable by scattering and sticking a fine moisture-absorptive material which has a higher refractive index than the quartz core of an optical fiber in a low humidity range on the surface of the quartz core. CONSTITUTION:The fine moisture-absorptive material A which has the higher refractive index than the surface-treated quartz core is scattered and stuck on the surface of the core, which is arranged in a measurement area 8 which is filled with gas to be measured such as air. A photodetector 10 detects the intensity of light from a light source 9 which is incident on the fiber core 7. Light which is reflected and propagated in the quartz core strikes on the interface between the core and material A to have optical loss. When this material A contains a little water, the refractive index decreases and the leak of water increases by water absorption until the quartz core and material A become equal in refractive index and scattered light propagated components into the quartz core increase. Consequently, the transmitted light in the fiber core 7 varies in intensity according to variation in the humidity of the gas to be measured and the temperature of the gas to be measured is found from the intensity of the transmitted light of the photodetector 10.

Inventor: OTA HIROYUKI
IPC: H01L21/331
Filed: 1994-03-18
Abstract: PURPOSE:To obtain a bipolar element wherein irregularity of electric characteristics is little, by forming a step-difference having a specified size, between the contact surface of a base electrode and a silicon substrate and the contact surface of an emitter electrode and the silicon substrate. CONSTITUTION:In a bipolar element having a structure wherein a base electrode 9 is adjacent to an element isolation film 3, a step-difference 14 is formed between the contact surface of a base electrode 9 and a silicon substrate 1 and the contact surface of an emitter electrode 11 and the silicon substrate 1. The size A of the step-difference 14 is larger than or equal to 0.03mum and smaller than or equal to 0.1mum. When the step-difference is too small, mixed impurities of an opposite conductivity type can not be eliminated, so that electric characteristics become unstable. When the step-difference is too large, stress becomes excessive, so that dislocation is generated and electric characteristics deteriorate. The step-difference is formed in the size range that the impurities of opposite conductivity type can be eliminated and the dislocation is not generated. Thereby a bipolar element excellent in electric characteristics can be obtained wherein the leak current is small when the level of integration is increased.
