IPC: F16K11/07
Filed: 1979-10-30
Abstract: PURPOSE: To provide flow control through turning a directional control valve, by forming a notched type liquid path with an increasing depth on a spool.

IPC: H01L21/60
Filed: 1989-06-01
Abstract: PURPOSE:To prevent the generation of a crack and a disconnection by a method wherein the width of the parts between the base film of conductive leads and bump electrodes is made narrow. CONSTITUTION:When bump electrodes 2 and conductive leads 3 are fixed thermally by pressure to each other by a bonding tool 5, a semiconductor element 1 and a base film 4 are caused a dimensional change due to a thermal expansion and the concentration of a tensile stress is generated on both ends of parts 3a between the film 4 of the leads 3 and the electrodes 2. At this time, the parts 3a between the film 4 and the electrodes 2 are respectively formed into a form having a central part of a narrow width. Thereby, the tensile stress is dispersed, the concentration of the stress is weakened and a crack in the leads 3 and the disconnection of the leads stop generating.

Abstract: PURPOSE: To prevent the decrease of wind pressure or generation of abnormal noise by constructing an air leakage prevention lapped part where a bell mouth and a centrifugal fan are lapped and thus preventing the air leadage from an inlet port of the bell mouth.  
     CONSTITUTION: A blower 15 with a centrifugal fan 14 is placed at the back of a heat exchanger 13 in a casing 10.
