Patent JP-H0362929-A (JP)
Title: Manufacture of semiconductor device
Inventor: HIKITA TOMOYUKI
IPC: H01L21/331
Filed: 1989-07-31
Abstract: PURPOSE:To form an emitter region readily by oxidizing only an exposed part under the state wherein a part of a high concentration impurity layer is exposed, and separating the impurities into a low concentration layer and a high concentration layer around said low concentration layer. CONSTITUTION:A nitride film 9 and an oxide film 8 are sequentially etched. A silicon layer 2 at a part corresponding to a collector forming region and a P<+> region 5a at a part corresponding to an emitter forming region are exposed. Thereafter, oxidation and drive-in are performed under the specified temperature/gas conditions. At this time, only the exposed part of the P<+> region 5a is oxidized. A large difference in surface concentration of the P<+> region 5a occurs. A base region 5 comprising an low concentration oxidized region P<-> and a high-concentration non-oxidized region P<+> is formed. Then, the oxide film formed by oxidation/drive-in is etched away with the silicon nitride film 9 as a mask. Thereafter, the N<+> impurities are deposited and driven under the specified conditions, and a collector region 6 and an emitter region 7 are formed.

Title: Welding equipment and cooling water device therefor
Inventor: HANDA KATSUMI
IPC: B23K9/32
Filed: 1996-07-30
Abstract: PROBLEM TO BE SOLVED: To surely achieve the arc-start without electric shock even when a person touches a cooling water equipment. SOLUTION: No high frequency current or high voltage DC current is applied to a case by covering a circulating device consisting of a tank 2 and a pump 4 with a case 21, and insulating the circulating device and the case 21, and the electric shock can be prevented. Because the high frequency or high voltage DC current does not return from the earthing of a cooling water equipment to the power source, the high frequency or high voltage DC current is surely applied to a tip of a water-cooled torch to surely achieve the arc-start.

Title: Rolling method for high polymer
Inventor: WATANABE KAZUO
IPC: B29C55/18
Filed: 1988-08-12
Abstract: PURPOSE:To enable drawing to be carried out in simple manufacturing facilities stably and efficiently by heating high polymer up to a predetermined temperature, after that, completing the rolling in rolling the material at low speed in the range of 0.1-1m/min in 1 pass, or only final pass of a plurality of passes. CONSTITUTION:By making a roll diameter as largely as possible and rolling speed as slowly as possible, the contact period of a material and roll becomes long, and the heat of the material is deprived by the roll, and besides the material temperature at an outlet is lowered considerably not being an ordinary temperature, so that it can be minimized in its elastic reversion. In the case of around 20mm of the press lowering rate, the roll diameter capable of rolling at 1 pass becomes around 600mm in consideration of the biting property, however, 1-2 times thereof, namely, the range of 600-1,200mm, is selected in consideration of the limitation in facilities. The rolling speed is selected by 0.1/min-1m/ min from the limitation in which an elastic reversion rate is obtained from various experiments, and if it is slower than this rate from a practical viewpoint, the productivity can not be ensured, whereas, if it is high than this rate, the elastic reversion becomes large.

Filed: 1983-10-26
Abstract: PURPOSE:To prevent the lack of quantity of heat by controlling the speed change stage of an automatic transmission in line with the heat load of an air conditioner and controlling the number of revolution of an engine while a car is running. CONSTITUTION:A heat load detecting means is connected to an air conditioner and, when a heat load, which is detected by the heat load detecting means becomes large, a change speed pattern or detected data are modified by a certain quantity so that the speed change stage to be controlled by a speed change controlling means becomes one on the further lower side. Thereby, when the heat load becomes large, the quantity of heat of the heat source of a cooler or a heater can be increased by increasing the number of revolution of an engine, ?securing a quantity of heat corresponding to the heat load.

Title: Line for filling and packaging
Inventor: SASAKI YASUYUKI
IPC: B65B11/12
Filed: 1993-07-20
Abstract: PURPOSE:To prevent operational efficiency of an entire line from dropping in constituting a filling and packaging line by connecting a first packaging device for producing a first package bag with a second packaging device for further packaging the above package bag to provide a second package bag in series. CONSTITUTION:A line buffer 30 for temporarily storing package bags produced by a first packaging device 20 is provided between the first packaging device 20 and a second packaging device 40, wherein during normal operation the first and second packaging devices are operated at the same production speed, and an approximate half of the maximum stock of the packaging bags are stored on the line buffer 30. Thus if one of the first and second devices stops, increasing or decreasing the amount of the bags on the line buffer 30 can eliminate influence to the other device. Further at the time of resuming operation, relative production speed for the first and second devices is changed, thereby recovering a stock amount on the line buffer.

Title: Differential amplifier circuit
Inventor: NAKAJIMA HIROKI
IPC: H03F3/45
Filed: 1988-08-11
Abstract: PURPOSE:To permit a large input signal amplitude at a low electric power by introducing a bipolar transistor as a diode for a level shifting. CONSTITUTION:Transistors Q1 and Q2 to connect a collector through respective resistances R1 and R2 to a first power source line and a collector are respectively connected through resistances R3 and R4 to the first power source line. Transistors Q3 and Q4 to connect the base to the connecting middle point of the collector of a transistor Q1 and a resistance R1 and the connecting middle point of the collector of a transistor Q2 and a resistance R2 and a collector are respectively connected to the first power source line. Thus, when the input output voltage is coincident to a ground potential, the current does not flow at resistances R5 and R6 which are the negative feedback resistances, and for the direct current bias conditions of respective parts of the circuit, the normal amplifying action of a transistor is secured. When the input output voltage is equal to the ground potential, since the current does not flow at the resistances R5 and R6, a low electric power can be attained.

Abstract: PROBLEM TO BE SOLVED: To dispense with a troublesome optical axis adjusting work for every time replacing an optical fiber and a connector by freely changeably providing a key part at a prescribed circumferential direction position of a ferrule stepwise or continuously. SOLUTION: A connector part 1 being in a state in which a key part 11 and the center of the tip 26a of an optical fiber are made to correspond is inserted into the axial center hole part 8 of the cylinder part to be connected 6 of a receptacle 3 and the key part 11 is inserted into a key groove 7. Thereafter, the optical axis of the tip 26a of the optical fiber and the optical axis of a lens 4 are made to coincide by finely adjusting the lens 4 or the cylinder part 6 in a flat plane orthogonal to the optical axis. Thus, a laser beam converged by the lens 4 coincides with the center of the tip 26a of the optical fiber and the entering of the beam into the optical fiber 26 is performed with high efficiency.  When the fiber cord and the connector are respectively replaced with a new fiber cord and a new connector, it is unnecessitated to perform the optical axis adjustment again by inserting a connector into the receptacle 3 while changingly adjusting the key part 11 so that the center of the tip of the optical fiber cord exists within the area 27 of a center angle around the key part 11.
