Title: Semiconductor element heat sink - has electrically insulating, but thermally conductive, plate between semiconductors and heat sink surface
Inventor: HOFMANN MANFRED
IPC: H01L23/373
Filed: 1978-08-26

Title: Four point support for measuring ruler - employs two-arm levers with counterweights to reduce bowing
Inventor: FRANK ADOLF DIPL ING DR TECHN
IPC: G01B5/00
Filed: 1978-11-07
Abstract: A two-arm lever (10) is constructed from a rectangular tube section (12) which is slit lengthwise to form a U-section. The lever arm (13) towards a ruler (1) carries support rollers (11) on which the ruller rests. The lever arm is supported by a smaller roller (14) against the under side of the ruler, so that a force (F) is applied at this point. This force is generated by a counterweight (F') mounted on the arm of the lever remote from the ruler. The support arrangement reduces bowing of the ruler and represents a closer approach to the optimum than the usual two-point support.
