Title: Controlling of nuclear reactor output
Inventor: ONO HIROSHI
IPC: G21C7/26
Filed: 1987-11-09
Abstract: PURPOSE:To enable a prompt and safe controlling of a nuclear reactor output, by controlling an openness of an adjusting valve 6 and a recirculation flow and by making a turbine generator output to follow to a load change. CONSTITUTION:A pressure control system controls a nuclear reactor pressure at a constant value and in case an adjusting valve 6 is operated and a main steam flow increases, a nuclear reactor pressure 30a decreases, therefore, the pressure deviation signal between the pressure 30a and a preset pressure value 31a is fed to a pressure regulator 19. Therewith, the regulator 19 generates a signal to the adjusting valve 6 so as to keep a nuclear reactor pressure constant and thus, in case a demand signal 15a for a governor free operation is fed to a governor filter 17, a steam flow is pushed back temporarily and a hollow portion appears in a response characteristics. Then a load demand signal 12a is also fed to a governor free compensator 25, the nuclear output is regulated through a recirculation system and the governor free operation is maintained. In this way, a prompt and safe controlling is attained.

Title: Method for replenishing developer liquid
Inventor: OISHI CHIKASHI
IPC: G03G15/10
Filed: 1990-10-19
Abstract: PURPOSE:To enable an amount of developer liquid and concentration of it within a developer tank to be kept constant by a method wherein a valve opening time of a solenoid valve is extended more than a valve opening time corresponding to a condensed developer liquid supplementing amount per one operation when a final supplementing time of a predetermined time of supplementation corresponding to the number of developing sheets and a full amount of condensed developer liquid remained in a tank is supplemented. CONSTITUTION:A predetermined valve opening time corresponding to an amount of supplementary liquid per one operation and a predetermined number of times of supplementing intermittently carried out in a developer liquid tank 19 are set. When a developing operation is carried out, the number of times of supplementing operation is counted for every time a predetermined number of developing sheets is set, and at the same time a solenoid valve 27 is opened only for a predetermined valve opening time, condensed developer liquid 25 is supplemented from a condensed developer liquid tank 26 into a developer liquid tank 19. This operation is repeated and when the counted number of the supplementing operation reaches a predetermined number of times, a valve opening degree and/or a valve closing time of the solenoid valve 27 is increased, a total amount of remained liquid within the condensed developer liquid tank 26 is supplied to the developer liquid tank 19. After this operation, the condensed developer liquid tank 26 is replaced with a new condensed developer liquid tank to continue a developing action for an electrophotography plating. With such an arrangement, it is possible to keep liquid amount and concentration of the developer liquid within the developer liquid tank.

Title: Data reception equipment
Inventor: HASHIDO SHIGEYUKI
IPC: H04L25/40
Filed: 1990-10-19
Abstract: PURPOSE:To improve the data reception precision by providing specific start bit detecting means, data bit discriminating means, and stop bit detecting means. CONSTITUTION:A start bit detecting means 100 receives serial data where a start bit of logical '0' and a stop bit of logical '1' are added before and after a prescribed number of data bits respectively, and this means judges detection of the start bit when logical '0' continues for an about half or longer of prescribed time length. A data bit discriminating means 200 extracts logical values at an about middle point of each of a prescribed number of set reception time areas and points of time before and after this middle point and diecriminates the logical value of each data bit by majority decision of three logical values. A stop bit detecting means 400 judges detection of the stop bit when logical '1' is decided by majority of these three logical values. Thus, the start bit and the stop bit are detected and the logical value of each data bit is discriminated even if the time area of each bit is varied, and the data reception precision is improved.

Title: Optical parts
Inventor: HAYAKAWA KOICHI
IPC: G02B6/26
Filed: 1988-11-08
Abstract: PURPOSE:To make optical parts to be used for demultiplexing, polarizing or light reducing an optical signal free from optical loses and complicated optical axis adjustment so as to reduce the manufacturing cost by putting an optical film between end faces at end sections of two optical fibers, with the end sections of the fibers being formed at prescribed angles. CONSTITUTION:End sections of bare parts 5 and 6 of two optical fibers 3 and 4, from which coatings are removed, are obliquely cut and polished at angles 50 deg. and the parts 5 and 6 are fixed to a base plate 7 in such a way that they are connected with each other the end faces thus formed with a polarizing film 2 between the end faces after their optical axes are aligned. Then the connected bare parts 5 and 6 are covered with a cover 8. When light rays having a wavelength 1,300nm in which P- and S-polarized light rays are coupled are made incident to the 1st optical fiber 3 by using the thus constituted optical parts 1, only 90% of the P-polarized light rays are emitted to the 2nd optical fiber 4. It is also possible to use a wavelength splitting film which selectively transmits the specific wavelength of multiplex optical signals or light reducing film which reduces light quantity as the optical film instead of the polarizing film 2.

Title: External storage device
Inventor: MUROTANI AKIRA
IPC: G06F13/00
Filed: 1995-10-30
Abstract: PROBLEM TO BE SOLVED: To provide an external storage device succeeding an I/O processing without the aid of a user and a host system when a fault occurs in a controller. SOLUTION: Before a host system 10 recognizes the fault of a controller 30, reports the fault to user/application and stops a job when the fault occurs in the controller 30, a controller 40 reads SCSI-ID which an SCSI port 31 in the controller 80 has from a common memory 50, registers SCSI-ID in the SCSI port 31 to an SCSI port 41 in the controller 40 and eliminates SCXSI-ID which the SCSI port 31 in the controller 30 has by a port address reset mechanism 45. Since SCSI-ID designated at the time of issuing an I/O request is succeeded between the controllers, the change of an I/O request issuing path by the host system becomes unnecessary. Furthermore, SCSI-ID can be succeeded without permitting the host system to recognize errors.

Title: Valve provided with excessive flow preventing valve
Inventor: HIKASA KATSUHIRO
IPC: F16K17/34
Filed: 1986-11-27
Abstract: PURPOSE:To prevent leakage during valve closing, by disposing a slidable valve element adapted to close at a predetermined flow rate, in the lower section of a seat. CONSTITUTION:A container is connected to the lead-in passage 1b side of a valve casing 1, and fluid is charged through a charge port on the lead-out passage side. At this time, a valve element 7 is depressed by charged fluid, overcoming a push-up urging means 9, and therefore a flow passage having a sufficient size may be ensured. Fluid is taken out from the charge port bit by bit for use. If a large flow rate exceeding a predetermined value is effected due to a failure in an extraction circuit or the like, the valve element 7 is pushed up by the fluid so as to close a hole port 1c. When a seat section 3 is depressed by rotating the handle 6 to close the valve seat if, the valve element 7 is forced to be depressed by the seat section 3 and is reset. Thus, it is possible to completely prevent leakage by means of the seat section.
