Patent JP-S5949384-A (JP)
Title: Gear pump
Inventor: KAWAKAMI MASARU
IPC: F04C13/00
Filed: 1982-09-14
Abstract: PURPOSE:To efficiently exclude foreign matter contained in fluid, by forming a groove extending from a tooth end of a gear to a portion near an axis of the gear on a surface of a pump chamber opposed to a tooth side surface. CONSTITUTION:Grooves 14 are formed on surfaces of a casing 4 and a casing cover 5 opposed to tooth side surfaces of gears 7 and 8. Clearances 15 are set to such a value as to be required for rotation of gears in disregard of fine particles. Although the fine particles contained in liquid to be fed tend to enter the clearances 15 during suction to discharge, they enter the grooves 14 as soon as they are sucked through a suction port 10 because the grooves 14 are arranged near the suction port 10, thereby preventing resistance to rotation of gears. Entrance or accumulation of fine particles in the clearances 15 at a portion without the grooves 14 is anticipated, however since the fine particles enter the grooves 14 every rotation of the gears 7 and 8, and are scraped by edges of the grooves 14 thereby to be sequentially excluded with rotation of the gears. Further, as the grooves 14 are arranged at an angle to the rotational direction of the gears 7 and 8, the scraped fine particles are induced toward the tooth end, and readily enter a liquid well 16, thus efficiently excluding the fine particles.

Title: Two-pole transfer switch
Inventor: NAGATA KUNIO
IPC: H01H23/00
Filed: 1987-06-27
Abstract: PURPOSE:To reduce the cost by insert-molding a switch case with different output directions of contact patterns. CONSTITUTION:Both OFF contact pieces 129, 130 are separately molded and are in an electrically noncontact state and differ from a driver seat switch case 25a on this point. The specific output direction is obtained as an individual seal switch. Since the contact patterns are same, these switch cases 25a, 25b can be manufactured by the insert molding from the same mold in common when a switch case is insert-molded. The production efficiency of the switch case is thereby improved and the cost is reduced.
