Title: Discharge lamp lighting device
Inventor: ASANO HIROYUKI
IPC: H05B41/24
Filed: 1997-10-27
Abstract: PROBLEM TO BE SOLVED: To reduce stress loaded on a circuit element constituting a control power circuit and supply stable control power voltage, by controlling one of positive and negative amplitudes of an alternating output voltage of an inverter circuit so as to be decreased when control power is higher than a given value, and by setting the decreased side voltage of positive and negative voltages of the output voltage to be the control power. SOLUTION: By changing on-duty of signal voltages Ho, Lo input from a control circuit 1 into switching elements Q1 , Q2 , output voltage of a control power circuit can be changed. For example, in a starting mode where high frequency voltage generated in a transformer T1 is high, when high frequency voltage with a low positive side peak is generated on the both sides of the transformer T1 as an unbalanced wave form where on-duty of the Ho of on- duties signal voltages Ho, Lo is larger, stress loaded on a circuit element can be reduced because the output voltage of a control power circuit becomes lower.

Abstract: PROBLEM TO BE SOLVED: To enable continuously recording even when recording regions are used up by constituting recordable regions to be expandable by reproducing, recompressing and rerecording recording signals on a disk, compressing and recording the signals again. SOLUTION: A microcomputer 16 reproduces a prescribed region of the disk 1 by a pickup 2 and regenerative signals are supplied to a data processor 8 via a reproducing amplifier 3 and ECC/DEC 5. The regenerative data are subjected to a recompression processing by the data processor 8 and are supplied to the pickup 2 again via the ECC/DEC 5 and a recording amplifier 4. The microcomputer 16 controls a servo part 7 and the recompressed signals are recorded again in a regenerative region by the pickup 2. Recording rate of 10 Mbit/s at this time is changed to 5 Mbit/s at the time of recompression- recording. That is, vacant regions can be produced on the disk 1 by recompression-recording.  Even when the vacant region on the disk is used up, recording can be done in the produced vacant regions and thereby recording time can be prolonged and the utilization efficiency of the disk 1 can be improved too.

Title: Numerical controller
Inventor: NAKAGAWA TERUO
IPC: G05B19/18
Filed: 1985-12-27
Abstract: PURPOSE:To improve the operability of the power supply operations by using a device which controls the supply and cut-off of power to a numerical control circuit and therefore preventing the power consumption with the unmanned operation carried out at night. CONSTITUTION:A numerical controller obtains a DC power supply from a rectifying circuit 11 via a switch 12 for AC power supply. A power supply controller 21 contains a timepiece circuit 24, a memory 22 which records previously the sequence of time to supply and cut off the power of the numerical controller, a driver 25 which opens and closes a switch 12, and a back-up power supply 26. When a command is received with operation of a key for actuation of the numerical control, the time sequence is read out of the memory 22. Then the driver 25 is driven at a set time point to turn on the switch 12. Thus the numerical controller is actuated and then stopped when the switch 12 is turned off. This eliminate the manual operation for open/close of a switch and improves the operability. Furthermore it is possible to avoid such a case where the undesired power is supplied to a numerical control circuit after the unmanned work is through or interrupted at night.
