Patent JP-S62209857-A (JP)
Title: Manufacture of semiconductor device
Inventor: GOTO HIROSHI
IPC: H01L29/732
Filed: 1986-03-10
Abstract: PURPOSE:To accelerate the operation of a bipolar transistor by forming an insulating film on the upper surface of a boron-doped polycrystalline silicon film, and then oxidizing it to prevent the upper surface of the film from being oxidized, thereby forming a base electrode of low resistance value. CONSTITUTION:A second insulating film 8 is formed in advance on a first polycrystalline semiconductor film 5 to which an impurity is implanted to become a first electrode blank. After the film 8 and the emitter forming region of the film 5 are removed to form a hole, the surface of the film 5 of the inner wall of the hole is oxidized to form a third insulating film 10. In other words, since the upper surface of the film 5 is covered with the film 8, if the first electrode is, for example, used as a base electrode, the electrode having a predetermined low resistance value can be readily formed as the purpose, and faster bipolar transistor can be accurately manufactured.

Filed: 1985-03-15
Abstract: PURPOSE:To improve the resolution of a control angle without increasing a calculating time by providing less significant bits of a control angle signal irrespectively of a calculation for deciding a gate control signal. CONSTITUTION:A 3-phase full-wave thyristor rectifier is composed by connecting in a bridge 6 thyristors T1-T6 with a power source line 1, and controlled on the basis of a 12-bit digital control angle signal which exhibits a control angle generated from a control angle signal generator 4. A digitized gate control signal generator 10of the controller calculates by a calculator 11 on the basis of 8 more significant bits alpha1 of the 12-bit signal of the generator 4 and the output B of the first counter 8, a deformation control angle information signal is obtained to generate a digitized gate control signal. 4 less significant bits alpha2 are output through the third latch 16 to the second latch circuit 15. Thus, a calculation for obtaining the gate control signal is performed on the basis of the output of the first counter 8, and high speed calculation is not made necessary.

Title: Atomic reactor core
Inventor: AZEKURA KAZUO
IPC: G21C7/27
Filed: 1991-03-18
Abstract: PURPOSE:To raise a fuel conversion ratio and increase the takeoff burnup of fuel by circulating a moderator having moderation cross section small (large) in the initial stage (in middle and following stage) of a running cycle, in a plenty of pipes provided within a core. CONSTITUTION:In the inside of a fuel assembly, a spectral shift pipe 1 of double pipe structure is inserted from the upside. The moderator circulating through the pipe 1 flows in from the upside and flows out from the upside. The excess reactivity is controlled while the conversion ratio is being raised by circulating heavy water in the initial stage of a running cycle, within the pipe 1. From the middle stage on of the running cycle when the core reactivity reduces, the reactivity can be raised and the takeoff burnup can be extended by circulating light water. In an exchange time of the fuel, the pipe 1 is pulled out upwards, and thereafter the fuel assembly is pulled up together with a channel box 2. The neutron absorber of boron, etc., is mixed in the moderator within the pipe 1 and that concentration is controlled. In this way, a control rod becomes useless and the structure of a core vessel can be simplified.

Filed: 1990-03-05
Abstract: PURPOSE:To collect effective information without executing a manual operation against the abnormality of a system by collecting the data of a main storage and a peripheral I/O onto an auxiliary storage part, and generating a crush dumping file. CONSTITUTION:Abnormality of a system is decided by a system program, and when the abnormality of a system is detected, it jumps to the inlet of a crush dumping program stored in a ROM 4. In the beginning, the size of a RAM 2, that is, a main storage is read from a RAM control part 3. Subsequently, a peripheral I/O constitution is read in from a system constitution file K in the auxiliary storage part 5. Next, from the main storage size and the peripheral I/O constitution which are read in, the address information of data to be collected is converted to a table, and an area size to be secured for a crush dumping operation on the auxiliary storage part 5 is calculated. Thereafter, the file of the calculated size is generated as the crush dumping file on the auxiliary storage part 5. In such a manner, in the case abnormality is generated in the system, effective information can be collected without executing a manual operation.
