Abstract: PROBLEM TO BE SOLVED: To implement the low noise operation of an optical direct amplifier in an optical repeater system. SOLUTION: An optical direct amplifier in an optical repeater system is provided with: optical direct amplifying means 1, 2, 6, 7 and 8 for amplifying input signal light wherein the wavelength of main signal light and that of monitoring control signal light in a transmission path are multiplexed; monitoring control signal light receiving means 3 and 12 that, after the input signal light has been amplified by the optical direct amplifying means, separate the monitoring control signal light from the amplified input signal light, and then receive the separated monitoring control signal light;  monitoring control signal light transmission means 13 and 14 that form output signal light by multiplexing the monitoring control signal light onto the main signal light in the transmission path separated by the monitoring control signal light receiving means, and then send out the output signal light to the optical direct amplifier in the optical repeater system located downstream. According to this method, passing losses attributable to the reception of the monitoring control signal are removed at the input stage of the optical direct amplifier, and hence the noise figure can be improved and the transmission characteristics can be improved.

Abstract: PURPOSE:To improve operability for a working tool as well as to make fine metalworking performable, by housing a drive transfer system, phasing gears adjacent to engagement between gears and chains, in a box provided with a bearing and a projecting guide. CONSTITUTION:A shaft 41 attaching an abrasive 2 is driven by engagement between fixed gears 42 and two endless-form chains 47 and 48, and these gears 42 are adjacently phased in the axial direction. A suchlike srive transfer system 4 is housed in a box 6, and a projecting guide is installed in each corresponding spot of these chains 47 and 48 on an inner wall, preventing them from falling off. If, so the drive transfer system 4 is of engaged construction between the gear 42 and chains 47 and 48, so that it can be compactly housed in the thin rectangular parallepipedic form box 6 for holding without demanding any complex support members, thus it is operable freely with a feed mechanism. Therefore, aiming at reduction in frictional force due to engagement between the gear 42 and these chains 47 and 48 and curtailment in a mounting space, thus operability for a machine tool 3 is improved and fine metalworking is performable.

Title: Data writing method to memory
Inventor: ONDA TOSHIKAZU
IPC: G11C7/00
Filed: 1982-08-09
Abstract: PURPOSE:To write a program and data to an RAM with no addition of hardware and software to each control, by using a master device to execute reading/ writing, and writing the memory contents of the master device to a memory of a slave device. CONSTITUTION:A CPU11 of a master device 1 reads the data out of an RAM15. In this case, no read control terminal is connected and therefore the data of an RAM24 is not read. The CPU11 reads only the data of the RAM15. Then the CPU11 writes the data to the RAM15 by means of a read address, and the same data is written to the same address of both RAM15 and RAM24, respectively, since these RAM15 and RAM24 are connected to each other. In such a way, the contents of the RAM15 are all written to the RAM24. When the writing of data is over, a slave device 2 functions as an independent measurement controller having the data on the measurement control sequence part to the RAM24. Then the device 2 starts an operation based on the measurement control sequence data of the RAM24.

Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of electric discharge by providing a space between a core and an outer frame to reduce the electric field gradient between the coil and the frame. SOLUTION: The lumped constant type kicker electromagnet is composed of a pair of Cu plate coils 12 (ground side potential 0 V), 14 (high voltage side potential 30 kV) disposed outside a beam duct 6, a core (iron) 20 disposed outside the coils 12, 14, and an outer frame 22 (potential 0 V) supporting the core 20 which is supported by a spacer 24. The frame 22 disposed outside the core 20 is grounded to the ground potential, this causing an electric field gradient between the coils 12, 14 and the outer frame 22 wherein the coils 12, 14 are not especially insulated but the space 26 is provided between the core 20 and the frame 22, thereby reducing the electric field gradient between the coils 12, 14 and the outer frame 22. Thus it is possible to prevent the electric discharge to improve the reliability and enable it in the air.

Title: Fuel injection unit
Inventor: KANEKO TAKASHI
IPC: F02M57/02
Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To reduce damage caused by the cavitation erosion of a spill deflector by providing the spill deflector opened/closed by a plunger and declining one passage hole made in the spill deflector such that it gives a rotational force to the spill deflector. SOLUTION: When a plunger 1 is lifted and its reed 1a opens an oil supply port 2a, the high pressure in a plunger space 21 is released to an oil supply system. The fuel jetted at high speeds collides with the inner peripheral surface of a spill deflector 3 to reduce velocity energy and then is discharged into an oil discharge passage 221. Since the fuel always flows between two passage holes 31, 32 of the spill deflector 3 and the passage holes 31, 32 are declined in the circumferential direction, a rotational force is produced on the spill deflector 3 and the positions where cavitation erosion is generated are uniformly distributed in the inner circumference, which prevents the generation of uneven erosion at a specified position.
