Title: Feedback control method of molding machine
Inventor: YAMADA AKIO
IPC: B22D17/32
Filed: 1994-09-14
Abstract: PURPOSE: To perform feedback control by a solenoid control valve slow in response by adding a preset open control output value and the feedback control output value by PID operation and driving a speed control solenoid valve on the basis of the addition result. CONSTITUTION: The speed set value Vo preset corresponding to the stroke of the piston rod of an injection cylinder 10 is inputted and the open output value corresponding to the speed set value is outputted to an adder 6 from an open output value calculation part 2. The difference (e) between the speed set value Vo outputted to a comparator 3 and the speed actually measured value Vm calculated on the basis of the stroke detected by an speed calculation part 12 and clock data is calculated to be subjected to PID operation in a PID operation part 4. At this time, when the speed actually measured value Vm reaches the stationary range near to the speed set value Vo in the speed calculation part 12, a signal CL clearing an integrated value is outputted to the PID operation part 4.  Feedback operation quantity (u) and the open output value are added by the adder 6 through an addition output value calculation part 5 and the addition result is outputted to a driver amplifier 8 after D/A conversion.

Title: Light injection synchronization device, optical receiver and optical communication equipment

IPC: H04B10/508
Filed: 1991-09-02
Abstract: PURPOSE:To obtain a high signal versus noise characteristic by providing a band pass frequency filter filtering an output light from an injection synchronization laser and an optical detector detecting directly an output light from the frequency filter to the equipment. CONSTITUTION:A light source 4 for an optical transmitter 1 is realized by employing a laser oscillated at a single frequency such as a distributed feedback semiconductor laser, a distributed black reflection type semiconductor laser, a semiconductor laser with an external resonator and a gas laser or the like. An optical modulator 5 is driven by a transmission signal 6. In the case of obtaining a signal light subject to on/off keying modulation, an amplitude modulator 5 is required. In this case, the amplitude modulator 5 applies OOK (On/Off Keying) modulation by a coherent component to a coherent light outputted from the light source 4. Furthermore, a frequency filter 9 is realized by an interference filter. Then a signal light outputted from the frequency filter 9 becomes an output of an optical injection synchronization device 7.

Title: Liquid injector
Inventor: WATANABE JUNICHI
IPC: B41J2/015
Filed: 1986-09-19
Abstract: PURPOSE:To obtain a liquid injector which has an extremely excellent driving characteristic or injection efficiency by setting the ratio of the effective deformation length l to the entire length L of a piezoelectric ceramic tube to l/L>=0.75. CONSTITUTION:The ratio of the effective deformation length l to the entire length L of a piezoelectric ceramic tube 1 is set to l/L>=0.75. As apparent from a graph showing the variation of an electromechanical coupling coefficient K' 31 of a radial direction when the ratio of the length l to the entire length L is altered, the coefficient K' 31 exhibits 0.5 or more in a range over 0.75 of the ratio, but the K' 31 is largely reduced in a range less than 0.75 of the ratio. Accordingly, since the K' 31 of the coefficient representing the electromechanical conversion performance in the radial direction of the tube 1 can be set to a high value, the driving characteristic or the injection efficiency can be improved.
