Title: Degaussing circuit for cathode ray tube display device
Inventor: ITO TAKASHI
IPC: H04N9/29
Filed: 1988-12-21
Abstract: PURPOSE:To execute degaussing operation at an arbitrary time by allowing an attenuation type sine wave alternative current to flow in a degaussing coil by a diode all wave rectifying circuit, transistor to control the value of the degaussing current and time constant circuit to change the conductive state of the transistor. CONSTITUTION:When a power source is turned on or a switch 15 is changed over from turning-on to turning-off, a both edge voltage Vc of a time constant capacitor 10 rises up with the passage of time by a time constant which is determined according to the resistance value of a time constant resistor 9 and the value of electrostatic capacity for the time constant capacitor 10. Reversely, the base current of a transistor 12 is decreased together with the increase of the both edge voltage Vc of the time constant capacitor 10. Accordingly, the current flowing between the collector and emitter of the transistor 12, namely, a degaussing current iL flowing to a degaussing coil 4 goes to be the sine wave current which is decreased reversely to the increase of the Vc. Thus, the degaussing operation can be started when the charge of the time constant capacitor 10 is zero. Thus, the degaussing operation can be executed arbitrarily by turning-on and off the switch 15.

Title: Pwm controlling circuit
Inventor: SAKAINO YUTAKA
IPC: H02P27/08
Filed: 1990-11-27
Abstract: PURPOSE:To enable a constant current control, even in a low current region, by connecting, a switch circuit for switching over the width of the pulse outputted from a monostable multivibrator circuit, with the monostable multivibrator circuit. CONSTITUTION:When the voltage generated by a current sensing resistor R3 is lower than the voltage at a terminal (+) of a comparator 4, switches 10, 11, 12 of upper sides are switched on, and the coil current values of a motor are made to increase. When the coil current values exceed desired current values respectively and the output of a comparator 4 is inverted, the output of a monostable multivibrator circuit 2 is brought into ON-state by the time, which is determined by the values of R and C of a time constant circuit section and by the lowered comparison voltage of a comparator in the monostable multivibrator circuit, the comparison voltage being lowered because a switch circuit 1 for switching over a pulse width is switched on. At this time, it is made possible that the coil current value comes lower than the desired current value. Thereby, the output A of the monostable multivibrator circuit 2 is again brought into a high level, and similar operations are repeated. Therefore, a low constant current control is performed.

The number of rotation is controlled by the control device 13 for controlling the number of rotation so as not to exceed a set value RPO or so as to be kept constant at the set value RPO when the number of rotation exceeds the set value. Accordingly, it is possible to prevent the number of rotation of the fan motor 7b from exceeding the set value RPO to generate excessive noise. Since noise can be prevented, a characteristic of the number of rotation and voltage of the fan motor 7b can be set high and then the reduction in the number of rotation caused by a decreased torque when the fan motor 7b is operated at a low voltage at 60Hz.

Also, when the inertial ball 7 moves in an orbital along the side wall of the housing 5, the inertia ball 7 contacts the contacting part, its movement direction is changed, the movement is regulated by the vibration-damping liquid 9, the continuous contact between the contact member 6 and the inertia ball 7 is cut off, and the continuous output of ON signal is avoided. Also, even if the regulation effect of the vibration-damping liquid 9 is reduced, malfunction can be prevented in cooperation with the contacting part.
