IPC: F01L9/11
Filed: 1984-03-15
Abstract: PURPOSE:To prevent an exhaust valve from seizing and sticking, by using an air spring as a valve spring so that the exhaust valve is rotated by compressed air which is discharged from an air chamber upon opening of the valve. CONSTITUTION:A piston 100 having saw tooth-like blades 102 is disposed in the air chamber 15 of an air spring for urging an exhaust valve 12 in the closing direction of the latter, and nozzles 103 are formed in the lateral wall of the air chamber.

Abstract: PURPOSE:To accurately position an external lead of a semiconductor device on an automatic wire bonder by using an external lead, which extends from the main surface of an insulating substrate to a conductive layer on the substrate, has a different reflectivity from the substrate. CONSTITUTION:An automatic wire bonder recognizes the position of a FET 6 by detecting its edge 12 so as to determine the position of a gate electrode where wire 8 is bonded. The end 11a of the external lead 3 to the gate is detected and thus the position of the lead 3 is recognized. The reflectivity of the lead 3 is compared with that of a ceramic substrate 2. Since they have different reflectivities, the edge 11a is easily detected and it is possible to accurately determine where the wire 8 is to be connected. Therefore, precision wire bonding is carried out for FETs.
