IPC: B29C37/02
Filed: 1982-04-30
Abstract: PURPOSE:To improve working efficiency by efficiently removing semiconductor flash adhered to the surface of a lead frame using a roller obtained by integrating and mixing grains to an elastic material and facilitate a removing work and save the labor through reduction in size of apparatus. CONSTITUTION:In a removing apparatus 3, rollers 3b, 3b' are respectively fixed to both shaft end portions of its rotating shaft 3a and both rollers 3b, 3b' are made capable of sliding the surface of a plurality of leads C projected between adjacent resin moldings 1, 1. Since the rollers 3b, 3b' are composed of elastic materials to which grains are mixed, the rollers are elastically in contact with the surface of lead frame A in such a way as slinding thereon and the mixed grains grind the flash D while the rollers rotate. Flash D can be removed efficiently from the surface of lead frame A by sliding the rotating rollers 3b, 3b' on the surface where the flash D of lead frame is sticked or by sliding the rotating rollers 3b, 3b' on the grinding surface of the lead frame A.

Title: Fluid type fan coupling device for cooling engine of automobile
Inventor: KIKUCHI YASUBEI
IPC: F16D35/00
Filed: 1980-06-02
Abstract: PURPOSE:To control the quantity of a cooling wind for cooling the engine of the automobile finely by controlling the number of revolution of a fan through the change of an ambient temperature and the change of the speed of revolution of a driving main shaft at the input side. CONSTITUTION:When an ambient temperature changes, the degree of curve of a band plate-shaped bimetal 9 alters, a tubular valve member 8 functions through a connecting rod 10 with the change and a fluid inflow hole 5' is opened and closed. When the speed of revolution of a revolution driving disc 11 exceeds fixed speed, a centrifugal valve V is slid in the radial outside direction along a bottom wall surface against the force of a spring 13 by the centrifugal force, and an outflow hole 11' is closed. When the speed of revolution drops, the hole is opened. Accordingly, the flow rate of a fluid lowers without regard to the ambient temperature and the number of revolution of the fan F drops during revolution at high speed, and the flow rate of the fluid is controlled in response to the ambient temperature and the number of revolution of the fan F is controlled during revolution at low speed. Thus, the quantity of the cooling wind can finely be controlled.
