Title: Manufacture of al-si alloy
Inventor: KAKEFUDA MASAHIKO
IPC: B22D1/00
Filed: 1985-02-12
Abstract: PURPOSE:To prevent the formation of blow holes in a casting by adding Sr to a part of a molten Al-Si alloy to be charged into a casting mold at a time and by charging the Sr added molten alloy into the mold at once. CONSTITUTION:A stalk 2 extending upward is placed in a holding furnace 1, and a molten Al-Si alloy is held in the furnace 1. The drag 4 of a casting mold 3 is set at the upper end of the stoker 2, and Sr is added to the molten alloy in the stalk 2 from the sprue of the drag 4 by about 0.005-0.05% of the amount of the molten alloy to be charged into the mold 3 at a time. The cope 6 is immediately fixed on the drag 4, and the Sr added molten alloy is charged into the mold 3 from the sprue 5. Thus, Si grains can be made fine without forming blow holes in the resulting casting.

Title: Low noise type pilot pressure drive passage switching valve
Inventor: YOKOYAMA KAZUHISA
IPC: F16K47/02
Filed: 1994-01-31
Abstract: PURPOSE:To reduce the noise generated in switching a passage by narrowing the pilot pressure intake port of a passage switching valve. CONSTITUTION:In the case where a passage mode is of fluid entrance/exit 5 4, pilot fluid flows from a pilot pressure intake port 6, shifting a spool 2 to the right, resulting in switching the current passage mode to 3 5. At this moment, the pilot fluid in the right side of the spool 2 is discharged from a pilot pressure intake port 7, but since the pilot pressure intake port 7 is narrowed, discharge resistance is generated, weakening the collision force of the spool 2 and a valve casing 1. Therefore, the noise generated in collision is reduced.

Title: Viscous coupling
Inventor: HAGIWARA MAKOTO
IPC: F16D35/00
Filed: 1990-02-07
Abstract: PURPOSE:To accurately perform characteristic adjustment with the use of an actuator without influence of inner pressure variation in a working chamber and miniaturize the actuator by equalizing in the operating direction, the diameters of sliding parts of both seals arranged between an operating member and respective transmitting members. CONSTITUTION:Respective sliding parts of a X-ring 59 (seal) and an O-ring 61 (seal) arranged between a control sleeve 55 (operating member) and a housing 43 (transmitting member) and between said sleeve 55 and a hub 45 (transmitting member) respectively are equalized in their diameters. Consequently, through the sleeve 55 is operated to move, the volume of a working chamber 57 is not varied, and also the inner pressure is not varied. Furthermore, since the sleeve 55 has no pressure receiving face in its operating direction, even if the inner pressure viaries due to temperature vairation, the force due to inner pressure variation is not applied on the sleeve 55. Therefore, torque transmitting characteristic can be accurately adjusted, regardless of operation to move the sleeve 55 and temperature variation, and independent of variation of the inner pressure. Hereby, the actuator 91 need not be formed into a large size.

Filed: 1988-02-09
Abstract: PURPOSE:To minimize operation trouble by giving an alarm when a time interval between signals made by existence detectors for detecting material existence found in consistent with a standard time obtained by dividing a distance between the detectors by a running speed of revolving rollers. CONSTITUTION:Flag switches 5a-5d as existence detectors are situated respectively between revolving rollers 3. When materials 1 are transferred on the rollers 3 in furnace and kick the flag face 51 of one of the switches 5a-5d, a flag switch pin 52 turns to close a limit switch 53, and this lights one of material detection indicator lamps 11 in alarm indicator 8, which respectively correspond to positions in the furnace. When a prescribed time has elapsed, lamps 13 for indicating load existence in zones go on to show load existence of material 1. Repeating this operation enables us to recognize passing of materials. In addition, a time from ON to OFF of the flag switch 5, or that from ON to ON of the next flag switch is measured and compared with a standard time, and when difference is larger than a specified allowance, occurrence of an abnormal situation is indicated by lighting of trouble indicator lamp 12 or by its flashing.

Abstract: PURPOSE:To provide antimicrobial property to semipermeable membrane by treating a semipermeable membrane comprising cellulose ester with organosilicone contg. a quat. ammonium salt group. CONSTITUTION:After forming a semipermeable membrane comprising a cellulose ester such as cellulose acetate an organosilicone contg. a quat. ammonium salt group as expressed by the formula is added to the membrane stirred in the water. (In the formula, R is alkoxy group, halogen atom, or acyl group, one of which may be OH, also; R' is <=20C bivalent hydrocarbon group or <=20C bivalent O- or N-contg. hydrocarbon group, which may have substituents; R'' is lower alkyl; R''' is 1-20C alkyl, alkenyl, cyclic aliphatic hydrocarbon group or aromatic group; n is a positive integer 1-3; X is an anion. The mixture is heated to perform hot water treatment and organosilicone treatment of the semipermeable membrane simultaneously. The membrane is then dehydrated by centrifuging and then heat-treated. Since the obtd. membrane itself has bactericidal action on microorganisms, propagation of microorganisms on the semipermeable membrane is prevented. When it is used for treatment of an org. raw material liquid, the amt. of bactericide to be added to the liquid can be reduced to the least. Clogging of the membrane due to putrefaction of org. substances on the membrane surface is also prevented. Exchange of treating liquid with water contg. bactericide which has been necessary at a temporary suspending of the membrane separation apparatus has become unnecessary.
