Title: Manufacture of semiconductor device
Inventor: MAKITA KOUJI
IPC: H01L21/331
Filed: 1983-07-11
Abstract: PURPOSE:To manufacture a high speed, high reliability bipolar semiconductor device in simple steps by forming a nonsingle crystal semiconductor film on the side of an insulating film in a hole, and then forming a single crystal semiconductor layer in the hole. CONSTITUTION:After an oxidized film 12 is formed on a P<-> type semiconductor substrate 11, a hole is formed, an N type impurity is implanted to the exposed substrate 11, thereby forming an N<+> type buried region 13. Subsequently, after a nonsingle crystal semiconductor film (e.g., a polycrystal silicon film) is accumulated on the entire surface, the film 13 is allowed to remain only on the side of the film 12 of the hole. Then, an N type single crystal semiconductor layer 15 is formed in the hole. A P type base region 38 is formed in the layer 15, and an N<+> type emitter region 39 is formed in the region 38.

Title: Device for measuring spark advance of engine
Inventor: MURATA NOBUO
IPC: F02P17/06
Filed: 1982-07-20
Abstract: PURPOSE:To enable the measurement of a spark advance even with an automobile having a delay in ignition by retarding quickly the timing for the light emission of a timing light to near the next top dead point, correcting the retarded phase with a correction means and knowing the normal spark advance. CONSTITUTION:The voltage from a variable resistor 1a and the voltage from a constant voltage source 3b are compared in a comparator 3e, the output whereof is fed with an A/D converter 1b to an arithmetic circuit 1f and the value corresponding to t1/t=spark advance is calculated in 1f in the case of measuring the spark advance of an automobile wherein the generation of an ignition signal before the cylinder attains the top dead point is desirable. On the other hand, the signals of a pulse generator 1c and a sensor 1d are fed to a counter 1e, by which t1/t is calculated and is inputted to a comparison and coincidence circuit 1g. When t1/t=spark advance coincides in the circuit 1g, an output is produced from said circuit. This output triggers a discharge tube 6 to emit light with a driving circuit 5 and the spark advance is read from the angle scale on an arithmetic display device 2. Where the ignition timing is designated as (t) and the time interval corresponding to the spark advance as t1.

Title: Composite membrane for separating gas
Inventor: RYUZAKI SHIGERU
IPC: B01D53/22
Filed: 1986-05-30
Abstract: PURPOSE:To obtain a composite membrane enhanced in separation ratio by a water surface developing method by blending both a membrane material having good adhesion for a porous support and the membrane material incapable of being independently deposited thereon and depositing the blended membrane materials on the porous support. CONSTITUTION:A composite membrane is constituted by depositing a thin membrane on a porous support having <=0.5mum surface pore diameter. The thin membrane is formed by blending both a membrane material having good adhesion for the porous support and the membrane material incapable of being directly deposited thereon. As the membrane material having good adhesion, the material which is capable of forming thin membrane to 0.01-0.1mum by a water surface developing method and has a siloxane structure is preferably used. As the membrane material incapable of being directly deposited, a polymer which can be formed into thin membrane by the water surface developing method and is the material having the separation ratio of oxygen and nitrogen higher than the former and having a fumaric acid ester structure is used.

Title: Simple self-supporting bag with faucet
Inventor: HIRATA ISAO
IPC: B65D30/16
Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To solve an inconvenience caused by lack of blance of the gravity center of a bag body. SOLUTION: When a bag content is filled to form the bag body 1A as a three-dimensional shape, the intersection 20 part of a side seal vertical part 18 and a first side seal inclined part 19 (or a slant seal part for a faucet-cum- first side seal inclined part) and the intersection 20 part of the part 18 and a second side seal inclined part 23 are forcibly folded and further, a constricting part 12 and the side seal vertical part 18 are inwardly pushed and hence, recesses 13 are forcedly formed at both right and left side seal parts 3 of the three-dimensional bag body 1A. Since the recesses are forcedly formed at specified positions, the self-supporting stability of the bag body 1A is increased. Hence, there is no fear that the recesses are greatly bent or folded to form a so-called gooseneck shape and a large deflection or bent arises to impair a commercial value.  In this way, an inconvenience caused by lack of balance of the gravity center of the bag body 1A can be solved.

Title: Light receiving body for encoder
Inventor: TAMURA KENICHI
IPC: H03M1/24
Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To obtain a light receiving body which reduces the power consumption of a backup driving operation in a power failure and which extends the backup driving time by a method wherein collectors of respective photodetectors on a one-chip board are formed independently of each other in the respective photodetectors. SOLUTION: A plurality of photodetectors 2a to 2n which are composed of bases B, emitters E and collectors C are formed independently of each other on a one-chip board 1, and the collectors C are formed independently of each other. The two photodetectors 2a, 2b as a part, to which a battery power supply for backup and an external power supply are connected, are driven by the battery power supply in a power failure, and they are driven by the external power supply in a normal state. The photodetectors 2c to 2n are constituted so as to be driven by only the external power supply. Consequently, in a backup operation in a power failure, only the two photodetectors 2a, 2b are driven by the battery power supply, and, e.g. only an absolute position is held.  As a result, since it is sufficient to drive only the two photodetectors 2a, 2b, the power consumption of a light receiving body can be reduced in the backup operation.

Title: Laser working device
Inventor: TAKAGI SHIGERU
IPC: B23K26/08
Filed: 1980-09-12
Abstract: PURPOSE:To improve the working accuracy of laser by controlling the outlet for laser light as a function for working speed during working. CONSTITUTION:When a table 7 begins to move by a movement start signal, the output proportional to its moving speed is emitted from a tachogenerator 11. In accordance with this, a controller 12 compares the output of the device 11 and a preset moving speed and keeps the laser output lower than the set value while the detected value is lower than the set value. Conversely when the detected value is equal to the set value or larger than the same, the preset laser output is emitted. Namely, the laser outlet is controlled to a trapezoidal shape of the figure. Thereby, the cutting width of the work 5 by the laser light 2 from a laser oscillator 1 is made constant.

IPC: B05B1/02
Filed: 1978-10-17
Abstract: PURPOSE: To provide uniformly distributed pattern in a coating process, by using a nozzle having circular pattern and by arranging electrode members near the injection mouth in continuous or intermittent concentric manner around the injection mouth.  
     CONSTITUTION: Compressed coating liquid fed from the gun body enters the spray nozzle 7, passes through the route 19, the first space 18a, the second space 18b, slit 23, volute room 24, and injection mouth 15 and is discharged into the air. The volute chamber 24 causes the coating liquid to whirl and the injection mouth that has a cicular (including doughnut) shape provides circularly sprayed pattern on the coated surface, This, even at lower injection pressure, reduces the chance that tail generates at the edge portion of pattern, providing uniformly distributed pattern. The rightmost of the nozzle 12 that forms electrode is shaped into a ring form and the electrodes are uniformly arranged to provide uniform electric field. All of these factors contribute to make pattern uniform and to enhance the efficiency of coating deposition to the object to be coated.
