Title: Pump
Inventor: YAMADA YUKIMI
IPC: F04B49/06
Filed: 1981-01-29
Abstract: PURPOSE:To prevent air infiltration and facilitate smooth and rapid water feeding operation by installing a water-level responsive switch, which actuates the operation of the pump  upon detecting adequate water level, and a valve, which opens or closes an air vent of the reserve tank in linkage with a float. CONSTITUTION:To operate the pump 17, maintenance of amount of priming water, required to submerge a pump runner 21 in the pump casing 20, is entrusted to a water-level responsive witch 12, swhich incorportes a valve 11  which, in turn, opens or closes an air vent 5 of the reserve tank 2 in link-motion  with a float 16. When water in the reserve tank 2 comes up to the level high  enough to keep the pump runner 21 in the pump casing 20 sufficiently under  water, the switch 12 discharges air above water level in the reserve tank 2 out  of the casing, and then actuates the pump 17 into operation. This ensures smooth and quick water feeding operation with no air infiltration.

Title: Controller for starting time of injection of magnetic field injection molding machine
Inventor: YOKOTA AKIRA
IPC: H01F41/02
Filed: 1986-01-27
Abstract: PURPOSE:To shorten a molding cycle hour, by a method wherein injection is started when a detected value of a magnetic field detecting device mounted on a tie bar for mold clamping arrives at a predetermined value. CONSTITUTION:A magnetic field is generated on a magnetic field injection molding machine 1 when a magnetic field generation coils 9, 10 are electrified after molds 2, 4 have been clamped. Then magnetic flux which is in proportion to the magnetic field generating within a cavity 7 is generated on a tie bar 6. As the result, voltage is generated in a detecting coil 12 and detected by a fluxmeter 13. This detected value is compared with a predetermined value by a presetting device 15 of starting magnetic flux of injection on a comparator 14. When the detected value arrives at the predetermined value, an injection starting signal is generated through the comparator 14 and the injection is started. This predetermined value of the starting magnetic flux of the injection is decided to be one obtained directly before arrival of magnetic flux passing through the tie bar 6 at the largest stabilized value. Accordingly, the molding cycle is shortened markedly.
