Title: Liquid crystal display device in printer and controlling method of operation of backlight thereof
Inventor: OMURA HIROMI
IPC: B41F13/00
Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To prolong the life of a backlight by extinguishing or flickering the backlight in a plate making operation and/or a printing operation. SOLUTION: On standby for printing, a backlight is lighted according to an operation signal from a control means. When a signal from a plate making operation detecting means is inputted, the control means judges that plate making is in progress (S1) and changes the operation signal for the backlight. At the time when the signal from the plate making operation detecting means is not inputted, the control means judges the presence or absence of a signal of a printing operation detecting means, and when the signal from the printing operation detecting means is inputted, it judges that printing is in progress (S2) and changes the operation signal for the backlight. By this change of the operation signal, the backlight is extinguished or lighted on the basis of an operation program (S3). In the case when the signals from the plate making and printing operation detecting means are not inputted, the operation signal sent to the backlight from the control means is not changed and the backlight is kept in a state of being lighted.

Title: Plunger driving device
Inventor: KUSABA RIYUUICHI
IPC: H01F7/18
Filed: 1983-01-20
Abstract: PURPOSE:To restrain the heat generation of a solenoid and thus eliminate bad influences on other apparatus by a method wherein the voltage impressed on the solenoid of a plunger is so controlled as to become a low voltage necessary to hold the plunger after attracting the plunger. CONSTITUTION:A plunger attraction signal is outputted from a generating circuit 301 and holds the output of a monostable multivibrator 303 at a certain time high level, and turning a transistor (TR) 305 into ON-state. Therefore, while the output of the monostable multivibrator 303 is in the period of the high level, a TR307 and the TR305 turn ON; in this period, a current flows to the solenoid 306 from a power source terminal 309 of a supply voltage higher than that of a power source 311, resulting in the attraction of the plunger of the solenoid 306. Thereafter, the output of the monostable multivibrator 303 turns at a low level, and accordingly TR's 304 and 307 turn OFF. Consequently, the supply voltage from the terminal 309 turns zero. But, from the point on, a low power source voltage is supplied from the terminal 311 to the solenoid 306 via a diode 310, and then the state of attraction of the plunger is kept.

Title: Detecting and transmitting circuit of circuit control signal
Inventor: SASADA TETSUICHIROU
IPC: G06F13/38
Filed: 1983-01-21
Abstract: PURPOSE:To extend the diversity of types and repeating frequencies of circuit control signals by using the software to perform the detection, the decision of meaning and the repeating frequency of the circuit control signal as well as the assembling and its repeating frequencies of the circuit control signal to be transmitted. CONSTITUTION:A CPU1 delivers a transmission signal and then the reset data to a data bus (h) after counting the interruption signals (a) in a prescribed frequency. The reset data is decoded by a decoder circuit 11 via latch circuits 7 and 8 and converted into a signal (t). This signal (t) is stored to a latch circuit 12 by a transmission synchronizing bit (j) and turned into a signal (k). Then a selector circuit 13 is controlled to deliver a normal transmission signal (l) excluding the circuit control signal to a transmission signal line (m). In such a way, the synchronism is fixed between the CPU operation and the reception frame timing as well as the CPU operation and the transmission frame timing. At the same time, a detecting/transmitting circuit for circuit control signal is obtained to transmit and receive the circuit control signal. Thus it is possible to increase and vary the types and repeating frequencies of the circuit control signals as long as the software capacity allows.
