Inventor: OTANI RIICHI
IPC: F02M61/18
Filed: 1990-07-17
Abstract: PURPOSE:To simply measure the distance from a nozzle center-axis to the nozzle hole positions on the seat face of a needle at high accuracy by introducing compressed fluid into a nozzle body in a state where the needles having various kinds of seat diameters capable of sealing the inlet parts of nozzle holes at the upstream and downstream positions, are inserted one at a time into an experimental model of the nozzle body to seal the nozzle holes. CONSTITUTION:In a state where a needle 8 is inserted into a nozzle body 2, the nozzle body 2 is mounted to a holder 16, and a cover 18 is clamped and fixed with bolts 17. In this state, when compressed air is fed into a hose 30, the space between the nozzle body 2 and the needle 8 is filled with compressed air. In this case, the needles 8 formed stepwise slightly thinner than the needle 8 having the diameter slightly larger than design-specifications, are inserted one at a time into the nozzle body 2 in sequence. When the seat position 4 of the needles 8 formed thinner, reaches the nozzle holes 5, air begins to leak from the nozzle holes 5 and is led to flow meters 14a, 14b,.... Thus, the quantity of leak from each of the nozzle holes 5a, 5b,... can be measured independently, and variations in the nozzle hole positions can be detected.

Title: Pll circuit
Inventor: MICHIMASA SHIRO
IPC: H03L7/10
Filed: 1991-07-31
Abstract: PURPOSE:To shorten the time required for synchronization of an input signal and an output signal of a voltage control oscillator, and also, to easily analyze the operation. CONSTITUTION:A phase comparator 1 detects a phase difference between an input signal R1 and an output signal V1 of a voltage control oscillator 5 which becomes a reference signal through a frequency divider 6, and outputs phase difference signals U, V. A loop filter 2 eliminates a higher harmonic component from the phase difference signals U, V outputted from the phase comparator 1. A control voltage source 3 is controlled by the phase difference signals U, V outputted from the phase comparator 1, and outputs positive potential, negative potential or zero potential. An analog adder 4 outputs a signal 400 which becomes a control voltage of the voltage control oscillator 5 by inputting an output signal 200 of the loop filter 2 and an output signal 300 of the control voltage source 3. The voltage control oscillator 5 varies an oscillation frequency of an output signal V1 in response to the output signal 400, and inputs it to the phase comparator 1 through the frequency divider 6.

Filed: 1990-07-20
Abstract: PURPOSE:To impart weak tension by continuous operation, and speed up winding operation, by independently installing a tension imparting means applying tension to a wire, and a tension direction controlling means for controlling the direction of the tension. CONSTITUTION:A wire presser 68 is loosely inserted into a hole 12A formed by linearly nicking a part of a cover 12, so as to be able to freely move up and down while being in contact with an end surface; the lower surface abuts always against the bottom surface of a slit 16 on account of self-weight. When a wire 1 reaches an inner lower end beveling surface 68A along the bottom surface, the wire presser 68 is pushed up by the wire 1, inserts the wire 1 between the lower surface and the bottom surface of the slit 16, and presses the wire 1 by the effect of the self-weight. By driving a solenoid 74 fixed to a base 71, an L-shaped lever 72 retained by a bearing 73 so as to be able to freely swing is pulled by a spring 75, and a press unit 70 presses the wire presser 68, thereby increasing the pinching pressure of the wire 1. When the excitation of the solenoid 74 is cut off, the lever 72 is pushed up by the solenoid 74 pressed down by a spring 76, and the wire presser 68 pinches the wire 1 only by self-weight.
