Title: Manufacture of semiconductor package
Inventor: KINOSHITA HIROBUMI
IPC: H01L23/28
Filed: 1986-12-17
Abstract: PURPOSE:To make a mold unnecessary, and reduce production time, by a method wherein an element mounting part and a conductive pattern are formed by etching the metal of a plywood composed of a resin substrate and a metal plate, and an end-portion of pattern is made a lead by eliminating a part of the resin substrate. CONSTITUTION:A plywood composed of a resin substrate 1 and metal plates 2 and 3 is prepared. An element mounting recess 5 is made. A conductive pattern 2a like a lead 62 is formed on the upper metal plate 2, and a plate 3a which prevents moisture from permeating is formed by the respective etching processes. The side surfaces 6 of the resin plate 1 are eliminated, the substrate 1 is made in a required dimension, and the end-portions of the conductive pattern 2a are left as a lead 7, which is bent on the side surfaces. An Si element 8 is fixed in the recess 5, which is connected to the pattern 2a, and is sealed with thermosetting resin 9. This method can correspond with constitutions, forms, and dimensions of various packages, and the seal mold is unnecessary. Thereby, production time can be reduced, and correspondence with design change is enabled.

Title: Cooling mechanism
Inventor: YOSHIDA TERUO
IPC: G11B33/14
Filed: 1990-11-06
Abstract: PURPOSE:To prevent an optical disk subsystem device, etc., from becoming unusable due to the lack of cooling air by monitoring the plugged-up state of a filter for cleaning cooling air fitted to the optical disk subsystem device, etc., based on the flow rate of the air led into the device. CONSTITUTION:When a filter 7 is plugged up with dust contained in air and the flow rate of cooling air passing through the filter 7 becomes less, a pressure is applied to a flap 8 closing an auxiliary air leading port 6b and, when the pressure becomes stronger than the force of a spring 10, the flap 8 rotates. As a result, the port 6b is opened and air is led into a device through an auxiliary filter 7a so as to supplement the insufficient amount of the cooling air. When the cooling air is supplemented, a projecting section 8a is moved to the position where the section 8a blocks the luminous flux of a photointerrupter 11. The photointerrupter 11 generates an electric signal due to the operations of the flap 8 and a display 12 displays the status of the port 6b through a controller 3. Therefore, it is displayed that the filter 7 has reached its usable limit and must be exchanged with another filter.

Abstract: PURPOSE:To prevent vibration from being transmitted to an output shaft by interposing compressed fluid between both sides of the concave grooves of an input shaft and the output shaft and the opposite side of both projections of an medium member, and holding the medium member under floating condition in relation to the input shaft and the output shaft. CONSTITUTION:Compressed air led from supply holes 15, 16 is throttled in throttles 21, 22 for generating static pressure to be supplied to bearing pockets 11, 12. The compressed air holds under floating condition the input shaft side projection 9 and the output shaft side projection 10 of a medium member 3 fitted in the concave groove 6 of an input shaft 1 and also maintains bearing gaps between both sides of the concave groove 6 and both sides of the projection 9 and between both sides of a concave groove 7 and both sides of the projection 10. Under this condition, the input shaft 1 is driven and thereby rotation is transmitted from the side of the concave groove 6 via the projection 9 to the medium member 3, and also from the projection 9 via the concave groove 7 of the output shaft 2 to the output shaft 2. In this case, although the input shaft 1 is oscillated upwards and downwards to oscillate the medium member 3 upwards and downwards, the vibration does not transmitted to the output shaft 2 due to the vibration absorption of the compressed air, and also the rightward and leftward vibration of the input shaft 1 does not transmit to the medium member 3.
