Title: Apparatus for producing single crystal
Inventor: ARAKI TAKASHI
IPC: C30B27/02
Filed: 1988-05-30
Abstract: PURPOSE:To enable the stable pull-up of even a single crystal having large diameter, by attaching a specific heat-shielding plate to a coracle in the pull-up of a single crystal from a molten raw material in the coracle placed in a crucible, thereby making the form of a solid-liquid interface to be flat or slight downward convex. CONSTITUTION:A coracle 1 is placed in a crucible for holding a molten raw material 2 and a single crystal 7 is pulled up from the molten raw material held in the coracle 1. The above apparatus for the production of single crystal is added with the following components. A ring-shaped heat-shielding plate 4 having an opening to pass the pulled-up crystal 7 is attached to the upper inner wall of the coracle or a coracle-supporting part. The heat 6 radiated through a gap between the coracle 1 and the pulled up crystal 7 can be shielded by the above means. Accordingly, the lowering of the surface temperature of the molten raw material 2 near the inner wall of the coracle 1 can be prevented and the form of a solid-liquid interface can be made to be flat or slight downward convex.

Abstract: PURPOSE:To prevent a careless short circuit without trouble at the time of assembling battery by attaching an insulating tape, which has a width nearly equal to the width of a lead piece made of the ribbon-shape metal foil, to the lead piece. CONSTITUTION:A lead electrode 20 consists of a lead piece 21, which is made of the ribbon-shape metal foil, and insulating tapes attached on both surfaces of the lead piece 21.

Title: Positioning device for paper feed cassette
Inventor: KURIMOTO AKIRA
IPC: G03G15/00
Filed: 1983-07-18
Abstract: PURPOSE:To easily position a paper feed cassette in an apparatus enclosure by engaging a cam surface with a cam follower and drawing the cassette in the apparatus enclosure by the urging force of a spring at the final stage of loading the paper feed cassette. CONSTITUTION:When a paper feed cassette is loaded in an enclosure of apparatus such as a copying machine or the like, at its final stage, the forward end of a tongue piece 23 advances into cam followers 32 of levers 29. With such advance, space between the cam followers 32 is expanded by portions 25b of the cam surfaces 25 against the urging force of a spring 31. With the further advance of the tongue piece 23 with the paper feed cassette, the boundary between the portions 25b and 25a of the cam surface 25 reaches the cam follower 32, until the portion 25a of the cam 25 is brought into contact with the cam follower 32. At this time, the cam follower 32 is liable to move to the narrower portion of the cam surface 25 due to the urging force of the spring 31, which results in that the tongue piece 23 is drawn to a frame 22 of the apparatus enclosure to bring the side plate 21 of the paper feed cassette into contact with a stopper 33, thereby stopping and positioning the paper feed cassette at a position suitably separated from the frame 22.
