Title: Method and apparatus for cutting strand
Inventor: KAWAKAMI KUNIO
IPC: C03B37/16
Filed: 1986-06-25
Abstract: PURPOSE:To improve workability in case of starting the feed of a strand to a feed roll by hanging the tip side of the strand to a guide lever and closely sticking it around the feed roll and winding the strand. CONSTITUTION:The tip side of a strand 1 is held and pulled in hand over hand and separated from a feed roll 20 and a guide roll 18. Then the switch of the feed roll 20 is turned on and after the feed roll 20 is started to be rotated, the strand 1 pulled till this time is passed through the guide roll 18. Successively after hanging it to a strand 32 from the upper part of the feed roll 20, it is pulled to the lower part of this side. Since the strand 1 is stuck with a binder content and has adhesive properties, it adheres around the circumferential surface of the feed roll 20. The strand 1 is gradually fed in the direction of cutter roll 22 so that it is folded from the midway thereof by the rotation of the roll 20. Finally it is engaged between the roll 20 and the cutter roll 22, the winding is completely finished, and simultaneously the cutting of the strand 1 is started.

Filed: 1977-12-13
Abstract: PURPOSE:To simplify the mechanism and operation of a cartridge shooting powder gun to increase the number of shooting bullets by providing ringlike tight lock between bottom surface and plug locking front surface with a locking unit as plug locking type. CONSTITUTION:Powder cartridge is inserted into a cartridge chamber 13 to lock a plug 3. Then, an ignitor 12 is opened. A detonator is inserted into a detonator hole 10 to thus close the ignitor 12. Then, a bullet is shot. Flame passes through a gate 11 into a cartiridge chamber 13 to burn the shooting powder. Thus, high pressure gas is generated to thereby shoot the bullet. The high pressure gas is expanded radially at bias-cut ring 4 to thus urge a locking ring 7. The ring 7 does not enter into the corner due to split rings 5, 6 but longitudinally expand along the axis of the gun strongly on the bottom 1-1 of the gun and pressure bearing plate 9 to  thereby prevent gas from leaking between the plug 3 and the bottom 1-1. Then, the plug 3 is opened to discharge the cartridge for next shooting preparation.

IPC: G06F13/10
Filed: 1994-06-30
Abstract: PURPOSE:To quicken the throughput of data. CONSTITUTION:A memory unit 10 consists of plural DRAMs which need to be refreshed. A DRAM controller 11 reads image data out of this memory unit 10 and sends the image data to respective peripheral circuits 13-16. The peripheral circuits 13-16 differ in time required for data processing. A data selector 17 selects one of the peripheral circuits 13-16 by a CPU 18. The CPU 18 sets wait times required for the data processing of the peripheral circuits in the DRAM controller 11 before reading the data out of the memory unit 10. The DRAM controller 11 clocks the time from the start of data read control and makes a wait request signal inactive a set wait time later to inform the CPU 18 of the timing of data fetch.

IPC: B41J2/05
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To enhance and efficiency of discharging energies and discharging pressure by preventing an influence of back waves at generating bubbles in the liquid flow path and making liquid discharge from the discharge port. SOLUTION: A heater 5 is set at a first liquid flow path 4 communicating to the discharge port 3 for giving liquid discharging energies to liquid.

Title: Current measuring device
Inventor: MIYAZAKI YOSHIO
IPC: G01R19/00
Filed: 1982-08-30
Abstract: PURPOSE:To realize easy and convenient measuring operation, by switching automatically a current for calibration and that for measurement, and recording reference amplification for the calibration and the current amplitude for the measurement on the same recording screen alternately and synchronously. CONSTITUTION:When an external signal START arrives, an oscillator 1 oscillates with a 10ms duty cycle to drive a relay K13. A monostable multivibrator 2, on the other hand, drives a relay K24 in 200ms to control a reference power source 5 for the calibration. Therefore, the contact 3-1 of the relay K13 and the contact 4-1 of the relay K24 are connected to the output side of the reference power source 5 for calibration for 200ms to input a signal to an AMP6. The relay K24 stops operating 200ms after the signal START and the input to the AMP6 is switched to the output of a shunt resistance SH9 by the contact 4-1. Assuming that a shunt resistance outputs 50mV when a 30A current flows, the outut of the resistance SH9 is equivalent to the amplitude value of the calibration reference power source 5 recorded on the recording paper of a photocoder 7 when the 30A current flows through the shunt resistance SH9. Consequently, the need for calibrating operation before load current measurement is eliminated and variance of the recorder (photocoder, etc.) is disregarded.
