Title: Ink jet recording device
Inventor: MIURA MASAYOSHI
IPC: B41J2/165
Filed: 1985-08-13
Abstract: PURPOSE:To prevent the losing of the balance of pressure on the stoppage and driving of an air supply means, and to obviate the discharge of unnecessary ink by covering an air discharge opening with a cap means and stopping the air supply means at approximately the same time as the covering of the air discharge opening when ink is not discharge from the air discharge opening. CONSTITUTION:An air supply pump 12 is operated and an air flow is fed to an air chamber 5 and an ink tank 7 during the operation of an ink jet recording device. When recording is completed, an ink jet recording head 1 is returned to the front of a cap means 28, and the cap means 18 is moved, is brought into contact with the front of the ink jet recording head 1, and covers an air discharge opening 9. The air supply pump 12 is stopped at approximately the same time as the covering of the air discharge opening. Since the air discharge opening 9 is covered with the cap means 18 as mentioned above, air is released only from a pressure control valve 15. Consequently, air pressure in the air chamber 5, an air flow path 6 and the ink tank 7 simultaneously drops, and lowers to the ambient pressure. Accordingly, the losing of pressure balance is obviated, thus preventing the discharge of unnecessary ink from the ink discharge opening 8.

Title: Photodetector
Inventor: TOMINAGA YOSHIKAZU
IPC: G01J5/02
Filed: 1997-06-18
Abstract: PROBLEM TO BE SOLVED: To add a light interceptor which can maintain an open state or a shut-off state, which is operated surely and whose power consumption is small by installing a square-wave oscillator or the like which oscillates a square-wave signal and a changeover signal which is synchronized with its rise. SOLUTION: A square-wave oscillator 1 outputs a square-wave signal (a) and a changeover signal (b) which is synchronized with its rise. A psudo differentiating circuit 2 outputs a signal (c) which time-differentiates the square-wave signal (b), and an amplifier circuit 3 amplifies the square-wave signal (a) so as to output a signal (a'). Whenever the changeover signal (b) is output, a signal changeover circuit 4 changes over the signal (c) and the signal (a') so as to output a signal waveform (d), and a power amplifier 5 amplifies the signal waveform (d) so as to excite an exciting coil by a voltage (d').  Then, since a large attraction force is generated between a core and a permanent magnet only during a short time in which a shutter used to shut off incidentlight is moved to an open position from a closed position, the shutter can be operated surely by increasing a slight power consumption, and the reliability of a light detecting apparatus is enhanced.

Title: Method and apparatus for adjusting quantity of fuel injection in diesel engine
Inventor: SUZUKI TAKAYUKI
IPC: F02D41/04
Filed: 1981-11-10
Abstract: PURPOSE:To reduce fuel cost and the complicatedness of operation by increasing the maximum quantity of fuel injected when the diesel engine is turned in the low revolution region of predetermined number of revolution or lower, its load is high and the position of a transmission gear is at prescribed stages or less. CONSTITUTION:When the transmission gear is positioned at third gear and the number of revolution of the engine is smaller than predetermined number of revolution n1, a stopper 6 is pulled in up to S1 by the signals of a controller 7. When an accelerator for acceleration is worked at its maximum under the state, the rack 5 of a fuel injection pump 1 is moved to the left until it contacts with the stopper 6 through a lever 4, and the quantity of injection is maximized. When the number of revolution reaches n1 or higher, the stopper 6 is projected up to S3 and the quantity of injection is lowered, and unnecessary fuel is cut off. When the number of revolution slowly drops and reaches n1 or lower when ascending a slope, the quantity of injection is increased because the stopper 6 is pulled in by means of the controller 7 while the accelerator is worked at its maximum. Accordingly, the complicatedness of operation is avoided, and fuel cost can be reduced.

Filed: 1986-07-30
Abstract: PURPOSE:To facilitate the starting operation on a slope by installing a one-way clutch onto a fixed body between the output side of an automatic clutch and a selecting mechanism. CONSTITUTION:The fixed rotor 51 of a one-way clutch 49 is fitted onto the bearing part 32a of a case 32, and a rotary rotor 53 is formed integrally with the shaft part of an output gear 42. The rotary rotor 53 can be revolved in the advance direction by a number of clutch pieces arranged between the rotary rotor 53 and a fixed rotor 51, and regulates the revolution in the retreat direction. When a car stops on a slope and starts again, the projection part 55b of a selecting dog 55 of a selecting mechanism 50 is engaged with a gear 44. In the no-load state in which a centrifugal clutch 15 is not connected, a turning moment in the retreat direction is generated by the weight of the car, and said turning moment can be regulated by the one-way clutch 49. Therefore, the retreat of the car can be automatically regulated without carrying out the manual brake operation, and starting operation is facilitated.

Title: Vacuum pump
Inventor: YOSHIDA KEIJI
IPC: F04B37/14
Filed: 1992-06-12
Abstract: PURPOSE:To provide a vacuum pump capable of being surely restarted only by slightly improving an atmospheric side second valve provided adjacent to a port communicating to an atmospheric chamber. CONSTITUTION:A second valve 18 on the atmospheric side in a vacuum pump for making a vacuum apparatus 24 exhausted by the reciprocation of a gas sucking means 12 is slightly bent to be opened by its own force in the stoppage of the gas sucking means 12, when pressure of a communicating port 17 is lower than predetermined one, and the second valve 18 on the atmospheric side is formed of a stainless steel plate. When the reciprocation of the gas sucking means 12 is once stopped, the second valve 18 on the atmospheric side is returned to the original state by its own force to open the communication port 17 and open a pump head chamber 11 to the atmosphere since the second valve 18 is bent originally to the opening side. Thus, the restart can be smoothly carried out without conventionally operating an unloader valve.

Filed: 1980-12-18
Abstract: PURPOSE:To modulate the phase independently of the frequency response characteristics of a PLL, by applying the modulation signal to a voltage-frequency converting circuit after being differentiated and adding the modulation signal before differentiation to a phase detection signal. CONSTITUTION:The modulation signal applied to an input terminal 1 is differentiated by a differentiating circuit 2 and is applied to a voltage-frequency converting circuit (VCO) 3 to obtain a modulated frequency signal PM at an output terminal 4, and the conventional modulation characteristics are obtained  by a negative feedback loop PLL consisting of a frequency divider 5, a phase detector 6, an adding circuit 9, an active filter 8m and the VCO3. However, the modulation characteristic wherein the modulation signal applied to the input terminal 1 is applied to the adding circuit 9 are proportional to the conventional PLL response characteristics because the frequency divider 5 and the phase detector 6 have not the frequency characteristics. Thus, the modulation signal is applied to both circuits in a specific level relation to obtain the flat modulation characteristics up to a wide band from a low band of the modulation frequency.
