Title: Fluorescent lamp device
Inventor: YASUDA TAKEO
IPC: H05B41/24
Filed: 1993-09-16
Abstract: PURPOSE:To make the stating operation reliable and minimize the risk of early blackening of a bulb by restricting the preheat current to a range where shortage of preheating is prevented and no end glow is generated, and thereby eliminating risk of end glow generation or shortage of the preheat. CONSTITUTION:When a fluorescent lamp 30 is started, a specified preheat current under control of a preheat control circuit 24 flows for the specified preheat time, which has been set in the control circuit 24, to filament electrodes 32, 32 mounted sealedly at the ends of the fluorescent lamp 30. Because the voltage between the two electrodes 32, 32 is lower than the discharge start voltage of the lamp 30, the inside of the discharging space is kept insulated, and all current flows from a choke ballast 27 to a closed circuitry consisting of the one electrode 32, a resonance capacitor 28, and the other electrode 32. Accordingly the specified preheat current under control of the control circuit 24 flows to the electrodes 32, 32 for the specified preheat time. A certain starting operation is established by restricting the preheat current into the range in which shortage of preheating is precluded and no end glow is generated, and also the bulb is prevented from early blackening.

Title: Semiconductor laser
Inventor: ODAGIRI YUICHI
IPC: H01S5/00
Filed: 1989-09-04
Abstract: PURPOSE:To enable the mounting of a semiconductor laser on a printed wiring board without bonding by a method wherein a semiconductor layer just under a second electrode is covered with another semiconductor layer whose conductivity type is different from that of a semiconductor layer just under a fist electrode so thick as to be lower than the level of an active layer. CONSTITUTION:In a semiconductor laser provided with a first and a second electrode, 22 and 23, which are isolated from each other by a groove 24 on the same plane, a semiconductor layer just under the second electrode 23 is covered with another semiconductor layer whose conductivity type is different from that of a semiconductor layer just under the first electrode 22 so thick as to be lower than the level of an active layer. Therefore, when a semiconductor laser is fixed to a printed wiring board 1 by welding making its electrode surface face downward, it can be kept stable in characteristics independent of the influence of an L component of a bonding gold wire or the L or the C component of a Peltier element on characteristics. By this setup, the mounting of a semiconductor laser can be realized without a bonding gold wire.

Title: Matting and its production
Inventor: TAKAMURA TORU
IPC: A61G7/05
Filed: 1994-08-31
Abstract: PURPOSE: To provide sheeting capable of preventing a bedsore by hermetically sealing silicone hydrogel prepd. by uniformly dispersing hydrogel of a highly water absorptive resin swollen with water with a soft packaging material. CONSTITUTION: The silicone hydrosol is prepd. by stirring and mixing an addition curing type liquid silicone rubber compsn. and the hydrogel of the highly water absorptive resin swollen with the water. In such a case, both are mixed to such a sea-and-island structure in which the silicone rubber matrix is the sea and the hydrogel of the highly water absorptive resin is the island. Next, the silicone hydrosol is converted into the silicone hydrogel by curing the liquid silicone rubber compsn. of the matrix, by which a shape retaining property is imparted to the gel. The hydrogel is then molded to a desired shape. In such a case, the curing is executed by resting the molding for 4 to 16 hours at room temp. or heating the molding for 10 minutes to 1 hour at 40 to 80 deg.C.  The matting 1 for preventing the bedsore has the structure formed by hermetically sealing the silicone hydrogel 2 into the thermally fused softenable packaging maternal 4 and is excellent in the function to adequately disperse the body pressure.

Title: Recording device
Inventor: KAWAZOE KENJI
IPC: B41J2/365
Filed: 1989-09-07
Abstract: PURPOSE:To change the regenerative correction at the time of image recording by a method wherein when a direct-writing recording is indicated by an indication unit, the rate of regenerative correction at a recording unit is controlled to be different from the time of transfer recording. CONSTITUTION:At either case of thermal transfer recording or recording to a heat-sensitive paper, the power connecting pulse to a thermal head 117 is constituted of a main pulse 164 (171) and a subsidiary pulse 165 (172). The pulse width which is changed for regenerative correction is the pulse width of the main pulse part, and the subsidiary pulse is not output when the immediately previous recording dot is '1' (there is a recording data), and when there is no recording date immediately before, the subsidiary pulse is output by a pulse which has a sufficiently smaller width then the pulse width of the main pulse. In the case of thermal transfer recording, the radiating quantity of the thermal head is smaller than the case of heat-sensitive recording. For this reason, when dots are recorded continuously, the width of the power connecting pulse (166-168) is corrected to be shorter, comparing to the case of heat-sensitive recording (pulse 173-175).

Title: Semlconductor device
Inventor: HASHIMOTO TSUTOMU
IPC: H01L21/331
Filed: 1986-09-29
Abstract: PURPOSE:To obtain excellent output characteristics even in a small current region, by providing a second base electrode in a transistor in an output stage, which is connected in a Darlington mode, and connecting an emitter and a first base through an internal resistance between the base electrodes. CONSTITUTION:A second base electrode 20, which is connected to an emitter electrode 21, is provided in an N-P-N output transistor Q2, which is connected in a Darlington mode, in addition to a first base electrode 19. The electrode 21 is connected to the electrode 20 through an internal resistance between the electrodes 19 and 20. Therefore, a voltage drop due to the internal resistance is less in a small current region, and an approximately short circuit state is present between the electrodes 21 and 19. Meanwhile, in a large current region, the potential of the electrode 19 is increased by the voltage due to the internal resistance and the transistor Q2 is driven. Thus, the output voltage characteristic in the small current region can be improved without changing the output voltage characteristic in the large current region.

Title: Manufacture of semiconductor device
Inventor: IEKURA YOSHIYUKI
IPC: H01L21/76
Filed: 1989-09-06
Abstract: PURPOSE:To prevent an inversion layer from being produced by an autodoping operation of impurities from a diffusion layer of an opposite conductivity type by a method wherein an autodoping amount of impurities in an epitaxial layer is increased only at an initial stage to form the epitaxial layer in which the autodoping amount of impurities from the diffusion layer of the opposite conductivity type on a substrate is largest. CONSTITUTION:An epitaxial layer is formed, by a chemical vapor growth method, on a semiconductor substrate where a high-concentration N-type diffusion layer formed of impurities of arsenic, phosphorus, antimony and the like and a high-concentration P-type diffusion layer formed of impurities of boron and the like. During this process, a doping amount of impurities into the epitaxial layer is increased intentionally for a definite time from a formation start of the epitaxial layer. Consequently, impurities from the substrate diffusion layer whose conductivity type is different from that of the epitaxial layer as a source of an inversion layer are offset. Thereby, it is possible to prevent the inversion layer from being produced.
