Title: Engaging tool
Inventor: KIN MEIGIYOKU
IPC: E05C19/16
Filed: 1980-07-26
Abstract: PURPOSE:To economize and secure engagement as well, by employing a plastic magnet as a permanent magnet with an engaging hole, and by combining a ferromagnetic plate with it. CONSTITUTION:A plastic magnet 1 has an engaging hole 1a through one side of its magnetic pole surface to the opposite surface. A ferromagnetic plate 2 is integrally buried and fixed to one side of its magnetic pole. This is inserted and integrally formed when the magnet 1 is formed. Another ferromagnetic plate 3 is set magnetically detachably on an empty magnetic pole side against the magnet 1. A ferromagnetic plate 3a, projected from the plate 3, has a magnetic contact with the plate 2 through a hole 1a of the magnet 1. Thus, a direct contact without any covers ensures stronger magnetic attachability and secures engagement. Less parts make lower prices.

Title: Oil pump for enclosed motor compressor
Inventor: HIRAHARA TAKUHO
IPC: F04B39/02
Filed: 1981-07-02
Abstract: PURPOSE:To reduce the power loss of an oil pump by providing a narrow path section at the opening of a conduction hole thereby preventing the mixture of oil into the suction gas. CONSTITUTION:A capillary tube is pressure inserted through the opening of a conduction hole 13f extending higher than the open ends 13b-13e to the sliding section in the oil supply hole 13 made in the drive shaft 4 while a narrow section 13g is provided. Since the diameter at the narrow section 13g is quite short, the flow speed of the refigerant gas will increase above the conduction hole 13f, thereby even if the dynamic pressure effect is high the amount of oil to be sucked is quite low because of the friction of the conduit thus to facilitate the discharging of the refrigerant gas. Consequently the mixture of oil into the suction gas is prevented thus to reduce the power loss of the oil pump.
