Patent JP-S5821002-A (JP)
Title: Motor drive circuit
Inventor: MATSUNAGA CHIHARU
IPC: F15B11/00
Filed: 1981-07-28
Abstract: PURPOSE:To prevent the abnormal rise in pressure at the time of additional acceleration, by providing a pressure control valve in a circuit connected between a tank and a supply/discharge circuit which connects a counterbalance valve and a directional control valve, so that the pressure control valve acts for a prescribed time. CONSTITUTION:When a directional control valve 4 is shifted to an operating position 4b, the pressure of oil from a pump 1 changes a counterbalance valve 7 to a left-hand position and the oil enters into the port 6a of a motor 6 and the oil from its other port 6b returns to a tank 2 so that the motor is driven. When the directional control valve 4 is returned to a neutral position and the driving of the motor 6 is stopped, the motor continues to rotate, because of the inertial force of the load, to perform pumping action. When the motor 6 is additionally accelerated by temporarily shifting the directional control valve 4 again to the operating position, a pressure control valve 14 keeps the pressure of an oil supply line 11a low for a response lag time to the shifting of the counterbalance valve 7 to an operating position, to avoid the enclosure of pressure between the valve 7 and the motor to prevent the abnormal rise in the pressure of the supply and the return lines.

Title: Broad band tuner
Inventor: FUJIMORI SHIGEO
IPC: H03D7/16
Filed: 1979-09-14
Abstract: PURPOSE:To stabilize broad band tuning by making it possible to set the 1st intermediate frequency independently of the oscillation frequency of a variable oscillator by obtaining the 1st local oscillation frequency signal from the difference in frequency between the variable oscillator and a fixed oscillator. CONSTITUTION:The 1st local oscillating circuit 26 is composed of variable oscillator 261, fixed oscillator 262 and mixer 263 and then generates the difference in frequency between oscillators 261 and 262 as the 1st local oscillation frequency signal. For this purpose, oscillator 261 uses that with the variation range of 3150- 3824MHz, for example, and the 1st intermediate frequency is set to a low frequency band of 358.75MHz only by setting the oscillation frequency of oscillator 262 to 2,700MHz and by varying the 1st local oscillation frequency between 450 and 1,124MHz. Thus, a signal inputted to the 1st mixer 25 is converted into a signal of the 1st intermediate frequency 358.75MHz, which is further converted into a signal  of normal intermediate frequency 58.75MHz by passing through the 2nd mixer 29  before being outputted to tuner output 31. In this way, the 1st intermeidate frequency is set independently of the oscillation frequency of the variable oscillator.

Abstract: PURPOSE:To change only the Q0 of a low frequency range without varying the sound pressure of an intermediate frequency range by winding at least two kinds of voice coils with different winding width and wire diameter onto the same bobbin in a dynamic speaker and varying the voltage ratio of the signal applied to each voice coil. CONSTITUTION:A cylindrical voice coil bobbin 6 is provided in a vibrating way between magnetic gaps g1 and g2. Two kinds of 1st and 2nd voice coils VC1, VC2 with different winding width are provided to the voice coil bobbin 6 and the winding width of the voice coils VC1, VC2 is selected to be lC1>lC2. When the voice coil is vibrated and moved by X with respect to a stationary position, the mean magnetic flux is expressed as a function of displacement X, the change in the mean magnetic flux of the voice coil VC2 is large with respect to the amplitude and the change in the mean magnetic flux of the voice coil VC1 with respect to the amplitude is small. Since the magnetic flux is maximum at the stationary position, the mean magnetic flux of the voice coil VC2 is less at a low frequency range where the amplitude is increased and the voice coil VC2 is mainly driven to obtain the equal sound pressure, the Q0 is improved and when the voice coil VC1 is driven mainly, the Q0 is lowered.

IPC: B41J2/205
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To form a high quality image by applying a constant voltage between a diaphragm and a drive electrode regardless of gradation and discharging that voltage to a level corresponding to the gradation thereby suppressing fluctuation in the hitting position of ink regardless of gradation. SOLUTION: A constant voltage is applied regardless of gradation between a diaphragm 55 provided in a pressurization chamber 51 and a drive electrode 72 facing the diaphragm based on a discharge data stored in a memory means and that voltage is discharged to a level corresponding to the gradation. Consequently, a pressure sufficient for jetting ink can be obtained in the pressurization chamber 51. Quantity of ink being pushed out from the chamber 51 can be regulated by lowering the discharge starting voltage to a level corresponding to the gradation. Since ink is imparted with a sufficient pressure regardless of the drop volume thereof, hitting position is not fluctuated.
