Title: Piezoelectric fuel injection valve
Inventor: KATSU MASAHIKO
IPC: H01L41/09
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To suppress the dispersion of a compressed load by providing a pressurizing piston by which the compressed load is applied to a piezoelectric actuator by fuel pressure introduced to a nozzle opening, and applying voltage to the piezoelectric actuator on condition that the fuel pressure applied in this pressurizing piston exceeds a predetermined value and increased. SOLUTION: When a fuel injection valve 7 is operated to be opened, each piezoelectric element 13 is contracted, and a pressurizing piston 11 is moved in association with the contraction of each piezoelectric element 13 so as to lower the pressure of a back pressure chamber 8. Hereby, pressure difference is generated between the back pressure chamber 8 and a fuel pressure chamber 3. By this pressure difference, a needle valve 2 opens a nozzle opening 1b against a coil spring 4, and high pressure fuel introduced to the fuel pressure chamber 3 is ejected from the nozzle opening 1b.  Next, when the fuel injection valve 7 is operated to be closed, each piezoelectric element 13 is extended, the pressure of the back pressure chamber 8 is increased by moving the pressurizing piston 11, the needle valve 2 is moved by pressure difference between the back pressure chamber 8 and the fuel pressure chamber 3 and the energization force of the coil spring 4 and seated on the seat part of a nozzle body 1, and fuel injection is stopped.

Title: Device and method for inspecting circuit board
Inventor: ANDO MORITOSHI
IPC: G01N21/956
Filed: 1989-12-18
Abstract: PURPOSE:To extend the inspection range obtained by one scanning and to enable the reduction of inspecting time by making the leaking or passing light coming from a circuit board to be inspected incident on an optical fiber plate and changing the outgoing direction. CONSTITUTION:The leaking or passing light from the printed circuit board 29 is made incident on the optical fiber plate 30 whereby the outgoing direction of leaking or passing light is made to change. The optical fiber plate is moved to up/down and left/right directions through a plate movement circuit 23. When a defect exists on the through-hole of circuit board 29, the light L1 diffused to the board 29 is leaked from the defective part of through-hole and put into the plate 30. The leak light entered to the plate 30 is traveled with totally reflecting in the fiber. Since the advancing direction of leak light exited from the plate 30 is thereby changed so that the light goes toward the incident enable area of wide-angle lens 24, the leak light in the region to be inspected apart from a receiving light detection system can be detected with high reproducibility.

Title: Leak preventing device for inverter device
Inventor: IWASAKI YOSHIHIRO
IPC: H02H7/122
Filed: 1989-12-18
Abstract: PURPOSE:To reduce the size and the cost by a method wherein the carrier frequency of an inverter, whose pulse width is modulated, is controlled based on leaked current detected by a leaked current detecting means and a non-contact current transformer, which are connected to the main body of the inverter device. CONSTITUTION:DC, obtained by rectifying an AC power source 1 through a rectifier 2 and smoothed by a smoother 3, is inputted into an inverter circuit 4. The pulse width modulation of the transistor 4a of the inverter 4 is effected by a control signal from a control means 18 to generate the 3-phase AC of pseudosinusoidal wave and drive a motor 5. Leaked current, generated upon ON/OFF of the transistor 4a due to the fluctuation of the ground voltage of the motor 5, is conducted through a detecting resistor 10 connected to the main body of the inverter to detect it by a non-contact current transformer 11. The output waveform of the current transformer 11 is shaped by a filter 12 and the level of the same is adjusted by a level modulating circuit 16. The adjusted level is compared with the allowable value of leaked current by a comparing circuit 17 and when the level is higher than the allowable value, the control means 18 effects the pulse width modulation of the transistor 4 and reduces the frequency of the modulated carrier.
