Title: Pressure diecasting process
Inventor: NOGUCHI KEIICHIRO
IPC: B22D27/09
Filed: 1990-05-15
Abstract: PURPOSE:To make the structure of a casting fine by supplying pressurized gas into the inside of a sand core to pressurize the molten metal and circulating the pressurized gas inside and outside the sand core to cool the sand core. CONSTITUTION:A casting mold 10 in which the sand core 18 is set is charged with the molten metal and this molten metal is pressurized by the compressed air supplied into a pressurizing cover 12 for pressure diecasting. The pressurized gas is supplied through a pressurized gas supply source 21, a supply passage 20 into the inside of the sand core 18. Then, the molten metal in the casting mold 10 is pressurized from the surface side of the sand core 18. Simultaneously, the pressurized gas supplied into the inside of the sand core 18 is circulated inside and outside the sand core 18 to cool the sand core 18. In this way, the molten metal is pressurized without deteriorating cooling properties in time of solidification of the molten metal.

Abstract: PURPOSE:To maintain water level in a bathtub at a desired level. CONSTITUTION:A water level adjustment device 31 to determine the desired water level WL is equipped on the side of the bathtub 21. The water level adjustment device 31 is linked to the main body 39 of the water level sensor 33 by means of a connector 32. The main body 39 is linked with a hair remover 23 via a transfer pipe 42 with a discharge valve 41. The water in the hair remover 23 is sucked by a filter pump 24 and sent to a filter 26. When a person enters the bathtub 21 and the water level rises above the desired water level WL, the water in the bathtub 27 flows into the water level adjustment device and is further transferred to the main body 39. When the water level in the main body 39 rises to the position of the upper limit electrode 45a, the discharage valve 41 opens. When a person gets out from the bathtub 21 and the water level falls below the desired water level WL, the water level in the main body 39 falls. When such water level falls to the position of the lower limit electrode 45b, the discharge valve 41 closes. Then a butterfly valve 47 opens to let in new water to the bathtub 21 from the water supply pipe 46.

Abstract: PURPOSE:To suppress the generation of bubbles even if a discharge system of a relatively low vacuum is used by injecting liquid crystals to panels by simultaneous vacuum injection. CONSTITUTION:This device is constituted of a vacuum chamber A and vacuum chamber B which are independent from each other. A vessel 2 for housing the liquid crystal 1 is housed in the one vacuum chamber A. This vessel 2 is driven by a motor 3 and drops the liquid crystal 1 at need. Both of the chamber A and the chamber B are evacuated to sufficiently evacuate the inside of the liquid crystal cell 5 via an injection hole 7 and a discharge hole 8. The vessel in the chamber A is then inclined by driving the motor 3 to drop the liquid crystal 1 near to the injection hole 7 enclosed by an O-ring 9 and to form a liquid crystal pool, by which the injection hole 7 is closed with the liquid crystal 1. The chamber A is thereafter leaked and the injection of the liquid crystal is started. The evacuation operation of the chamber B is kept continued during the injection of the liquid crystal and the air in the liquid crystal cell 5 is kept sucked from the discharge hole 8.
