IPC: H04N5/953
Filed: 1983-03-22
Abstract: PURPOSE:To prevent color blurring by expanding time axis of a reproducing time axis compression luminance signal and a reproducing time axis compressing line sequential color difference signal from a same timing position as that at the time axis compression respectively even if a reproducing time axis fluctuation is included in a reproduced H signal. CONSTITUTION:A pulse in following low reproducing time axis fluctuation of the reproduced H signal extracted from a voltage controlled oscillator 42 in the 1st phase locked loop PLL39 is impressed to a monostable multivibrator 44 constituting a delay circuit. The amount of delay is controlled by output signal of a loop filter 41 for the monostable multivibrator 44. Then, an output delay pulse from the monostable multivibrator 44 is applied to a phase comparator 46 constituting the 2nd PLL45, and after the phase is compared with the phase of a signal from a counter 50, the result is given to a voltage controlled oscillator 48. The clock signal is fed to a latch circuit from terminals 51, 54 and 55 via counters 49, 52 and 53 respectively. Thus, the time axis of the time axis compressing luminance signal and the time axis compressing line sequential color difference signal is expanded respectively in the same timing as that at the time axis compression.

Two piezoelectric ceramic plates 5a, 5b are pasted on a fixation part 2a on the surface, and a second flexure vibrator 6 is constituted in an cantilever state. When an AC voltage is applied to the piezoelectric ceramic plate 3, the center beam 2 causes flexure vibrations in the up-and-down direction. When an AC voltage is applied to the piezoelectric ceramic plates 5a, 5b, they cause bend vibrations in arrow directions Ya, Yb. When AC voltages whose phase has been shifted mutually are applied across the piezoelectric ceramic plates 3 and 5a, 5b, a contact member 7 at a free end P causes oval vibrations. As a result, it is possible to stably take out a driving force.

Title: Fuel injection device for internal combustion engine
Inventor: TADA RYOICHI
IPC: F02M69/04
Filed: 1995-03-08
Abstract: PURPOSE: To suppress receipt of heat from the internal combustion engine side to a minimum limit and to reduce an amount of fuel steam generated in the internal passage of an fuel injection valve. CONSTITUTION: A heat insulating properties insulator 70 is located between the stepped part 64 of an engine head 61 and the magnetic pipe 23 of a fuel injection valve 10 and a peripheral groove or an axial groove 82 is formed in the outer periphery of the insulator 70. Since an air layer is formed on the groove 82 part, an air layer 81 performs heat insulation operation, whereby an amount of heat transferred from the engine head 61 side to the fuel injection valve 10 side is suppressed. Thus, during the high temperature restarting of an engine, a heat receipt amount of fuel in the internal passage of the fuel injection valve 10 is relatively reduced. Thus, since an amount of fuel vapor generated in the internal passage is reduced, a ratio in which a fuel passage is disturbed by fuel vapor is reduced and the stable high temperature restarting of the engine is practicable.

Abstract: PURPOSE:To facilitate a force control for balancing a linear motion part, in whatever attitude it may be placed, by providing a means moving and driving the first mover, having a work tool of almost the same mass in a linear drive part, and the second mover of counter weight synchronously in a reverse direction to each other. CONSTITUTION:By rotating the first and second arms, a linear drive part 10b can take an arbitrary direction containing a gravitational force direction component. Next, when the first mover 9 and a servo motor 11 are rotated, power is transmitted to a ball screw 12 moving a nut 14 moving the first mover 9. Here because a ball screw 15 forms a thread reverse to the ball screw 12, the second mover 10 is moved in a reverse direction to the first mover 9. That is, each center of gravity of the first and second movers 9, 10 is placed in a position relation always in line symmetry with an axial line 6 serving as the center. As a result, a linear motion part, in whatever attitude it may be placed, can be left as balanced, and a force control can be facilitated with only desired torque.
