Patent JP-H022533-A (JP)
Title: Method and apparatus for amplifying light signal
Inventor: ERENOA JIYOON TAABOTSUKUSU
IPC: H04B10/2581
Filed: 1989-01-12
Abstract: PURPOSE: To make it possible to use lower pump energy by containing a fluorescent material capable of generating stimulation discharge in one core in an optical fiber having two mono-mode cores arranged at a uniform interval. CONSTITUTION: Two optical cores 2, 4 are arranged in a common clad 6 and held at a uniform interval through a fiber having a certain length. The materials, diameters and refractive indexes of the two cores 2, 4 are so selected that the cores 2, 4 have respectively different propagation constants and the two propagation constants are made coincident at wavelength λs. The core 4 has a fluorescent material capable of generating stimulation discharge at a wavelength equal or extremely close to the wavelength. Consequently, an optical signal is reciprocally moved between the two cores 2, 4 due to photocoupling and lower wavelength pump energy can be used.

Title: Manufacture of cold forging die
Inventor: HAGITA HEIJI
IPC: B21J13/02
Filed: 1989-01-11
Abstract: PURPOSE:To obtain a die difficult to break insert material by making up at least one of an outer ring and an intermediate ring of maraging steel and giving specified values respectively to a press-in allowance of the insert material into the intermediate ring and a press-in allowance of the intermediate ring into the outer ring. CONSTITUTION:The press-in allowance of the insert material 3 into the intermediate ring 4 is made up to 0.4-0.5% and that of the intermediate ring 4 into the outer ring 5 is made up to 0.6-0.8% for assembling them. Maraging steel is used to one or both of the intermediate ring 4 and the outer ring 5 and they are assembled in a suitable press-in allowance. Maraging steel is a steel containing Ni, Co, Ti, etc., and since the yield strength after aging is higher than the tool steel by performing age hardening treatment to martensite structure at a low temperature, assembly can be made in a large press-in allowance. Since large compression stress from the outside to the inside can be obtained to the insert material of cemented carbide such as WC-Co groups, etc., the maraging steel can resist fully to the tensile stress by the forging pressure to the outside.

Title: Resetting method from fuel cut of electronic fuel controller
Inventor: SUGIMOTO ATSUSHI
IPC: F02D41/12
Filed: 1993-01-13
Abstract: PURPOSE:To stabilize a throttle stroke till reset from a fuel cut and prevent the worsening of drivability due to this fuel cut from occurring by installing a fuel-cut step, a reset line setting step and a fuel injection resetting step there. CONSTITUTION:Both fuel-cut steps 103 and 114 cut a flow of fuel injection to each cylinder of an internal combustion engine at a time when a parameter value, which represents a driving state of the engine, was less than the preset fuel-cut line. In addition, reset line setting steps 107 and 109 are renewing such a value as being superposed with the specified value on the load parameter value one after another while the load parameter value is less than the fuel-cut line and the value is decreased. In this connection, a fuel injection resetting step resets the fuel injection to each cylinder when the load parameter value has exceeded the resetting line. With this constitution, a fuel cut in time of deceleration is quickly performable.

Title: Valve for fluid
Inventor: SHIODA ISAO
IPC: F16K1/14
Filed: 1989-01-11
Abstract: PURPOSE:To make a configuration simple as well as to reduce loss in pressure by forming a linear fluid passage, pressing a valve body seating on a valve seat with pressure by a spring from the side of an inflow port, and thereby providing the outer circumference of the passage with a circular lever which presses a valve stem with pressure slidably toward the valve body from the circumference of the passage on the side of fluid out-flow. CONSTITUTION:Each hole is bored into a valve main body 1 against a ball shaped valve body 5 while being directed obliquely toward the center of the ball 5 from the outer circumferential section on the downstream side so that each valve stem 10 is thereby inserted into each hole. The combination of each hole and each valve stem 10 is provided for three places on the circumference, and each valve stem 10 is made slidable. When either place of a circular lever 12 is pushed on toward the center side of a pipe line, at least, one out of the valve stems 10 is pushed into the valve body 5 so that the valve body 5 is separated from a valve seat 3 while the body resists against a spring 6 so as to let fluid pass through. When the inner abutting section of the circular lever 12 is formed in such a way that its acting surface 15 is roughly normal to the axial direction of the valve stem 10, smoothness in operation shall be improved. By this constitution, a fluid passage becomes linear while being simplified, thereby mk[ing it possible to reduce loss in pressure.

Title: Method of driving piezoelectric transformer
Inventor: MORIMURA YOSHIO
IPC: H01L41/08
Filed: 1979-01-20
Abstract: PURPOSE: To stabilize the output of a piezoelectric transformer in a high voltage power supply  using the transformer by the negative feedback of pulse width control type.   
     CONSTITUTION: An oscillating transformer 7 is driven in push-pull state by a drive circuit 8 and  transistors 9, 10 to thus drive a piezoelectric transformer 6. The drive current of the transformer  6 is detected by inserting a series resistor 16. The drive voltage is displaced at its phase at 90°  with a capacitor 17 and a resistor 18 inserted across both ends of the transformer 7 to set the voltage in phase with the current. Thus, the current is converted to a voltage by a phase detector 15.  Then, the frequency is counted at a voltage controlled oscillator 14. The sectified output voltage  V 0  of the transformer 6 is compared by a comparator 11 with standard voltage E, and also compared with the voltage of the oscillator by a comparator 13. Thus, the pulse output corresponding  to the error level is applied to the drive circuit 8. When the output voltage V 0  is lowered, the  drive pulse width of the transformer 7 is increased to thereby raise the voltage of the fundamental  component of the oscillated frequency at the secondary side of the transformer 7. Thus, the drive  current of the transformer 6 is increased to thereby increase the output. Accordingly, the output  of the transformer is stabilized with respect to the load variation.
