Title: Solenoid driving device
Inventor: KAMIYA RYUJI
IPC: B41J2/30
Filed: 1988-10-27
Abstract: PURPOSE:To prevent abnormalities of heating or the like from occurring by a method wherein when abnormalities in a circuit such as shortage of a solenoid, shortage of a control transistor, etc., occur, electrification control is inhibited. CONSTITUTION:A CPU 17 controls an I/O port 13 based on a program data of a ROM 14 to perform solenoid check treatment. When input Vo to an input terminal of the I/O port 13 is at a low level, an electrification circuit to a solenoid 1 is judged to be normal, and this check treatment is ended. Further, when the input Vo is at a high level, abnormalities are judged to exist in the electrification circuit to the solenoid 1, an alarm lamp 18 is lighted and besides, program control of the solenoid on and thereafter is inhibited. Since electrification to the solenoid 1 is thus inhibited when abnormalities exist in the electrification circuit to the solenoid 1, circuit parts neither generate heat nor ignite owing to occurrence of abnormalities.

Filed: 1988-10-28
Abstract: PURPOSE:To prevent saturation of a cathode ray tube cathode drive transistor(TR) with inexpensive circuit constitution by providing a means detecting a voltage in response to a collector current of the cathode drive TR and superimposing the voltage waveform onto a contrast DC (current) control voltage, a color saturation DC control voltage in a polarity suppressing the collector current. CONSTITUTION:A voltage in response to the collector current of TRs 6-8 is detected by a resistor 17. The voltage is amplified inversely by a TR22. The voltage waveform is superimposed on the voltage of a color saturation variable resistor VR4 with AC coupling through a resistor 24 and a capacitor 25. Moreover, the voltage waveform is also superimposed on the voltage of a contrast variable resistor VR5 through a resistor 26 and a capacitor 27. If the cathode emission is deteriorated by the voltage waveform and the collector amplitude of the drive TR is increased, negative feedback is applied to the color saturation and the amplitude of contrast thereby preventing the saturation of the drive TR.

IPC: G02B27/00
Filed: 1989-10-17
Abstract: PURPOSE:To obtain an excellent projected image having uniform brightness distribution by arranging a rotation-symmetric optical element whose cross-sectional shape is formed of two inclined parallel transmission surfaces, correcting the lowering of a luminous flux near the center of the cross section of the luminous flux emitted from a light source and uniformizing the distribution of the luminous flux. CONSTITUTION:The rotation-symmetric optical element 50 whose cross-sectional shape is formed of two inclined parallel transmission surfaces is arranged in the luminous flux emitted from a light source means 30, so that the lowering of the luminous flux near the center of the cross section of the luminous flux emitted from the light source is corrected and the distribution of the luminous flux is uniformized. Namely, the illuminating luminous flux 4 is refracted and transmitted by the optical element 50 and turned into the illuminating luminous flux 40 whose diameter is reduced. At such a time, the light beams b1 and b2 on an outer periphery become the light beams beta1 an beta2 and the light beams a1 and a2 near the center become one light beam alphaby reducing the diameter thereof. Thus, the luminous flux lowering part near the center is eliminated and the uniformity of the distribution of the luminous flux on the cross section of the illuminating luminous flux is improved, thereby obtaining the excellent projected image.
