Patent JP-S62660-A (JP)
Title: Plunger type injection pump
Inventor: KASAHARA SHIGENOBU
IPC: F02M39/02
Filed: 1985-06-25
Abstract: PURPOSE:To send identical oil amount with a half of prior stroke of a plunger by inserting a pair of opposed plungers in one plunger barrel and driving these plungers with separate cams respectively. CONSTITUTION:When a pair of cams 4 are rotated synchronously in the same direction, rollers 16 are driven by these cams to reciprocate vertically and a pair of plungers 3 slide vertically synchronously so that fuel is forcibly sent from a pipe 9 to a fuel gallery 8. Thus, the fuel is supplied from a fuel supply hole 2b into a plunger barrel 2 and compressed by a pair of plungers 3 to be sent from a central portion 2a to a delivery valve 5. Further, high pressure fuel is sent to an injection pipe 6 and injected into a combustion chamber of engine. Thus since a pair of plungers 3 approach each other vertically within the plunger barrel 2 with identical stroke and timing, a half of prior stroke of each plunger 3 will do to send same amount of oil as prior one.

Title: Noncontact power supply circuit
Inventor: NAGAI TAMIJI
IPC: H02M3/28
Filed: 1998-05-21
Abstract: PROBLEM TO BE SOLVED: To provide a noncontact power supply circuit which is able to suppress the supply of a large power to a load at no-load or a light load time, to avoid overheating and to improve safety. SOLUTION: A pulse-type load signal current, corresponding to a load current, is applied to a signal transmission load circuit 21 connected to a secondary winding 4b side of an output transformer 4, by superposing the signal current upon the own current of the circuit 21 for transmitting the load signal current to a primary winding 4a side of the output transformer 4 through electromagnetic induction coupling. The load signal current is applied to the primary winding 4a, a diode 9 and a resistor 7 and detected by a current detection circuit 10. An oscillation frequency variable circuit 11 is made to vary the oscillation frequency of an oscillation circuit 12, in accordance with the detected value of the current detection circuit 10 so as to vary the switching period of a MOS transistor 6 and hence the chopping period of a DC voltage on the primary side.  With this constitution, a small power is supplied to a secondary side at no-load or a light load time and a large power is supplied to the secondary side, when the load signal current from the secondary side is detected.

Title: Optical scanner device
Inventor: YAMADA OSAMU
IPC: G02F1/31
Filed: 1989-06-01
Abstract: PURPOSE:To pass parallel light through a liquid crystal plane and a prism, to deflect it in the deflection direction of the prism, and to make a random high speed optical scan by opening a liquid crystal plate behind the prism which has the desired deflection direction. CONSTITUTION:The liquid crystal plate 4 has liquid crystal gratings arrayed in matrix and prisms 5 which differ in deflection direction from one another are arrayed on the respective liquid crystal gratings to constitute a scanning plate. Light beam 6 such as parallel monochromatic light is inputted to the entire surface of the scanning plate from behind and the liquid crystal gratings on the back surfaces of the respective prisms are opened and closed in order to make the light beam 6 scan in two dimensions. Consequently, the scanning point can freely be varied by changing the positions of the liquid crystal gratings which are opened and closed, so an optional scanning such as a circular scanning, a spiral scanning, an interlaced scanning, and a random scanning, not to mention a linear scanning can be made. Further, there is no mechanical moving part and the scanning can be made under the ON-OFF opening/closing control of the liquid crystal gratings, so the fast scanning can be made.

Title: Electronic braking circuit for motor
Inventor: KITAGAWA SHIGERU
IPC: H02P3/12
Filed: 1982-08-12
Abstract: PURPOSE:To stop a revolution rapidly after the conduction of the motor is interrupted by absorbing the counter electromotive force of the motor generated when the revolution of the motor is stopped through a transistor and a diode added to a drive circuit. CONSTITUTION:When a switch 4 is changed over to the ground side, the switching transistor 2 is turned OFF while the base of the transistor 5 is brought to ground potential. Since the motor 1 continues to be turned at that time, the counter electromotive force of the motor is applied to the emitter of the transistor 5, and the transistor 5 is turned ON. Accordingly, counter electromotive force is absorbed to ground through the transistor 5, and damps in a short time. That is, the motor 1 is brought to the state in which counter electromotive force is short-circuited substantially, thus preventing revolution due to the inertia of the motor 1.

Abstract: PURPOSE:To prevent dust and papers from being blown off by exhaust air and to make a belt unnecessary, by a method wherein a turbine is revolved by the exhaust air of an electric blower and the air through the turbine is exhausted out of exhaust holes on the surface of a rotary brush. CONSTITUTION:After dust-containing air is led into a dust-collecting bag 30 is a dust chamber 29 from an air intake chamber 33 through a hose 38, the fine dust in the air is also passed through a filter 40 provided under the dust collecting bag 30. After that, the air is led, through an exhaust way 35, from an electric blower 23 to a turbine 37, and exhausted to the air intake chamber 33 out of exhaust holes 34 through the inside of a hollow rotary-brush 32. By driving against the turbine 37, in this manner, the exhaust air revolves the turbine 37, and then the rotary-brush 32 is revolved. Since the exhaust is blown on a carpet and the dust contained in the carpet is blown off, also, by being exhausted out of the exhaust holes 34 of the rotary-brush 32, it is possible to improve dust-collecting efficiency. Since the exhaust holes 34 are also provided near each brush 39, the exhaust blows against each the brush 39 and removes the dust adhering to it. Since the exhaust imparts driving force to the rotary-brush, its belt is not necessary for it, and such troubles as the belt is cut are eliminated.
