Title: Variable displacement pump
Inventor: OTAKI MIZUO
IPC: F15D1/08
Filed: 1994-02-28
Abstract: PURPOSE:To prevent loss of power and pressure rise of operating oil by diminishing the discharge quantity of a pump chamber when the load on a pump discharge side passage is small. CONSTITUTION:A cam ring 3 is eccentrically rotatably arranged along the outer circumference of a rotor 1, and a pump chamber c is formed between the rotor 1 and the cam ring 3. An orifice 27 is interposed on a pump discharge side passage. A piston 9 energized in an initial regulation position by a spring 10 for return is connected to the cam ring 3. The piston 9 is operated in response to a differential pressure between those before and behind the orifice 27. A regulation position adjusting mechanism 31 which advances the initial regulation position of the piston 9 when orifice forward pressure becomes below the set value is provided. When the load on the pump discharge side passage is diminished and the orifice forward pressure drops below the set value, the regulation position adjusting mechanism 31 advances the initial regulation position of the piston 9, and eccentric quantities of the rotor 1 and the cam ring 3 are diminished. As a result, the discharge quantity of the pump chamber c is reduced.

Title: Signal reproduction system
Inventor: HOSAKA YASUO
IPC: G11B11/08
Filed: 1982-02-26
Abstract: PURPOSE:To prevent applied charges and space charges from coupling with each other again during reproduction, by setting the fundamental frequency f0 of a resonating circuit so that the time wherein charges applied into the conductive substrate side of a recording medium reach the positions of space charges during reproduction is longer than the time 1/2f0 corresponding to a half cycle of the  fundamental frequency f0. CONSTITUTION:For reproduction, charges 41 are applied to the conductive substrate side 11 from an inductance element 23 supplied with a high frequency signal of f0 from a high-frequency oscillator 21 through an inductance element 22. Those applied charges 41 move toward space charges 16 as shown by an arrow 42 and are attempted to couple with the space charges 16. Since, however, an alternating electric field of frequency f0 operates on the recording medium 10 during reproduction, a reverse electric field operates on the charges 41 moving as shown by the arrow 42 so that they are drawn back as shown by an arrow 43 a time 1/2f0 later. For this purpose, the f0 is so selected that they are drawn back at a position shown by a dotted line 44 by the reverse electric field.

Abstract: PURPOSE:To radiate a radio wave in a direction in parallel with a face of a ground plate by arranging 1st and 2nd metallic plates above the ground plate and short-circuiting both ends opposite to each other of both metallic plates with the ground plate and the metallic plates respectively. CONSTITUTION:A radio wave in a frequency f1 fed from a coaxial connector 4a stimulates an electric field between a ground plate 1 and a 1st metallic plate 2a. Then a radio wave having the same directivity pattern as that of a loop antenna whose length is equal to the circumferential length of a metallic plate 2a is radiated between a ground plate 1 and the 1st metallic plate 2a. Moreover, a radio wave in a frequency f2 fed from a coaxial connector 4b excites an electric field between the ground plate being the 1st metallic plate 2a and the 2nd metallic plate 2b. Then a radio wave having the directivity pattern the same as that of the loop antenna taking the circumferential length of the plate 2b as the entire length is radiated. Thus, a radio wave is radiated in the same plane as the ground plate 1 and the antenna is used for an antenna using the two frequencies f1 and f2 in common.

Filed: 1994-02-28
Abstract: PURPOSE:To ensure the stability of a termination voltage by connecting two voltage generating circuits in series to provide a voltage being a sum of voltages of both circuits to an output circuit and applying a voltage at the connecting point to the termination resistor as the termination voltage. CONSTITUTION:Since a voltage V1+V2 is applied to an output circuit 48 as a power supply voltage and the voltage V2 is applied to a termination resistor 52 as a termination voltage VTT, a signal whose voltage V2 is an intermediate voltage is transmitted. Since a voltage generating circuit 37 is formed by connecting voltage generating circuits 38, 39 in series, even when a current is outputted from a voltage output terminal 41 or a current is received thereby, the voltage at the terminal 41 is maintained at the voltage V2 to ensure the stability of the termination voltage VTT equal to be V2. Furthermore, when a signal is not sent through a bus line 51, since no current flows to a termination resistor 52, the power consumption is reduced.
