Title: Multi-conversation process control system
Inventor: ENTEI HAYAMI
IPC: G06F15/00
Filed: 1988-12-15
Abstract: PURPOSE:To eliminate the structural limitation of an application program by saving the contents of a working area for secondary program including the resetting point information to a caller program into a scratch pad file additionally acquired against a communication instruction produced by the secondary program to a work station and then restoring the contents of the working area when the communication instruction is over. CONSTITUTION:When a main program 19 calls a secondary program 20, the contents of a register including a resetting point address of the relevant time point, etc., are stored in a prescribed resetting point information store area 22. The contents of the communication instruction produced by the program 20 are saved into the secondary SPF 25-1 - 25-n corresponding to each work station and restored there. Therefore the resetting point is never confused to the program 19 from the program 20 even in case the program 20 carries out a communication instruction in a multi-conversation process. Thus the communi cation instruction can be freely used within the program 20 and the structural limitation is eliminated to an application program.

Title: Clock generation circuit for data transfer
Inventor: OTANI AKIO
IPC: G06F13/42
Filed: 1990-11-21
Abstract: PURPOSE:To prevent the lack of transfer data and the transfer of erroneous data by returning an enable terminal to a countable state when transfer data is prepared. CONSTITUTION:If the output of an Q-output T5 in FF14 is H when the clock of T1 is inputted eight times, the output of a gate 12 becomes L and the ENP input of a counter 10 becomes L. Counting up is not executed even if the clock is inputted to a CLK terminal by T1 and the state of QD and RCO outputs do not change from QA of the counter 10. Then, the QD output of the counter 10 is held in H as it is until a signal line 6 becomes L, FF 14 is cleared and T5 becomes L. Thus, a transfer clock output line 3 changes in H as it is until the fetch of data terminates and it becomes L after the fetch of data terminates. Thus, data can be transferred without transferring erroneous data if data is transferred in synchronizing with a clock output.

Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To reduce noise by permitting a supply voltage intermitting circuit to reduce a rate of on-time of an AC voltage when a light source is darkly lit and lowering a voltage value of an AC voltage. SOLUTION: When a cold cathode-ray tube 2 is set to be dark, a given dimming signal is inputted from a dimming signal generating circuit 6 to a dimming PWM generating circuit 5 and a dimming voltage generating circuit. The dimming voltage generating circuit then supplies a low voltage to a tube voltage generating circuit 3, and the dimming PWM generating circuit 5 inputs a PWM signal based on a dimming signal to the tube voltage generating circuit 3. Thereby, the tube voltage generating circuit 3 is short in on-time and supplies a low tube voltage to a cold cathode-ray tube 2. When brightness of the cold cathode-ray tube 2 is increased in this state, on time is lengthened, and the voltage value is increased.  When brightness of the cold cathode-ray tube 2 reaches a given value, the intermission of the tube voltage is eliminated, and a consecutive AC wave of the tube voltage is generated.
