Title: Base material of container for freezing storage
Inventor: SHINONOME OSAMI
IPC: C08L23/06
Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To provide a base material of a container for freezing storage which is at least made of metallocene catalyst linear low density polyethylene below the prescribed density value or mainly made thereof, excellent in formability, and excellent in the low temperature resistance and impact resistance.

Title: Power supply device for laser oscillator
Inventor: YONEKURA MIKIO
IPC: H01S3/097
Filed: 1989-07-11
Abstract: PURPOSE:To overcome the delay of time and shorten processing hours by providing a constant voltage control circuit in addition to a constant current control circuit and then, changing over the conventional control circuit to the above constant voltage control circuit while operations are suspended. CONSTITUTION:When an electric current command is expressed by Im, it is detected by a detecting circuit 17. As a switching circuit 19 connects a constant current control circuit (a) to a control circuit 11, a discharge current is Im. When processing operations are suspended and the current command is made zero, the detection circuit 17 detects it. As the switching circuit 19 connects a constant voltage control circuit (b) to the control circuit 11, output voltage of a main power supply 5 comes to voltage V0-alpha that is obtained just before discharging. Once the current command is issued, the current rises immediately and after time T2, it comes to Im. In such a case, output voltage is expressed by Vm. As a result, this approach eliminates the need for having time corresponding to charge time in the capacitor of the main power supply 5 and then, working efficiency is improved.

Title: Sampling measuring method
Inventor: SAKANO TAKUO
IPC: H03M1/10
Filed: 1985-08-12
Abstract: PURPOSE:To enable the quick sampling of a signal to be measured by sampling a signal with the delay of the scheduled time from the 2nd clock and simultaneously changing a start address generating a digital word signal. CONSTITUTION:A DAC 3 outputs a pseudo sine wave corresponding to a digital word. A trigger generation clock signal source 9 is constructed with a counter or a frequency divider, receives a clock A from a clock signal source 7 and synchronizes such that it generates one clock B from N-number of clocks A. Then the source 9 gives a trigger signal to a sampling circuit 5, which samples the output signal of the DAC 3 in response to the trigger signal. However, said circuit 5 generates a sampling pulse SP with the delay of the scheduled time after it receives the trigger signal. For instance, it generates the SP after Ti X (N/2) time has expired since it received the trigger signal. This time delay can be easily obtained by a counter, the frequency divider, etc., with the aid of the clock B of the clock signal source 7. Thus measurement equivalent to the sampling measurement of signals to be measured during one period can be speedily made.
