Title: Surface protective film of semiconductor device
Inventor: SAITO KAZUYUKI
IPC: H01L21/31
Filed: 1987-08-13
Abstract: PURPOSE:To prevent separation of bonding wires from an electrode part in polyimide curing, by providing a protruding part between the electrode part and the central part of a semiconductor element. CONSTITUTION:A protective film 6 is formed in a region other than an electrode part 2 on the surface of a semiconductor element 1. In the forming steps of the protective film 6, a thick part is locally provided at the inner side (side of the central part) in the vicinity of the electrode part. Thus a protruding part 7 is formed. Therefore, even if polyimide liquid 5 is dropped on the surface of the semiconductor element 1, the polyimide liquid does not reach the electrode part 2 because the protruding part 7 serves the role of a barrier. The liquid is present only on the region surrounded with the protruding part 7. Therefore, the polyimide liquid 5 is not attached to fixing parts between the electrode part 2 and bonding wires 3. Even if the polyimide liquid 5 is condensed during curing in a curing furnace, the condensing force does not act on the parts between the bonding wires 3 and the electrode part 2. The separation of the bonding wires 3 from the electrode part 2 is prevented.

Abstract: PURPOSE: To check an action condition of a safety device by detecting a voltage appearing at terminals of an electric fuel pump, and feeding it back to an electronic engine control device. CONSTITUTION: A voltage between terminals of a fuel pump 16 is feed back to an electronic engine control device 10 through a conductor ECOM.

Title: Sluice valve gear for vacuum heating furnace
Inventor: KATO TAKEO
IPC: F27B9/26
Filed: 1987-08-17
Abstract: PURPOSE: To prolong the service life of a sluice valve device and, at the same time, to improve the degree of the vacuum in a vacuum chamber by providing a sluice valve on a first shaft which is attached in parallel to the work passage of the vacuum chamber at an interval from the passage and rotatably providing a heat insulating shutter on a second shaft. CONSTITUTION: A work 4 is carried in a vacuum chamber 1 through a passing port 5. When the work 4 is carried in the chamber 1, the heat insulating shutter 15 of a second shaft 12 blocks the passage of the work 4 and the sluice valve 10 of a first shaft 11 closes a passing port 6. During the heating of the work 4, the soaking property of the work 4 is improved, because the shutter 15 prevents radiation of the heat. When the heat treatment on the work 4 is completed, the sluice valve 10 is opened and the shutter 15 rotates to the position at which the shutter 15 protects the front face of the valve 10 and protects the packing of the valve 10 from heat. Since a rotary vacuum seal is adopted, in addition, no gas enrolling nor oil evaporation occurs. Therefore, the degree of the vacuum in the vacuum chamber 1 is improved and the service life of a sluice valve device is prolonged.

Title: Position indication controller
Inventor: WATABE KAZUO
IPC: G06F3/038
Filed: 1984-09-28
Abstract: PURPOSE:To shift a cursor in an optional direction at an optional speed and to indicate quickly an optional point by using a detector to cover a part of a surface of an optical sensor which is irradiated by a light source and detecting the vertical direction of a ball by the output of the optical sensor. CONSTITUTION:The vertical direction of a ball 51 is detected as follows. That is, the light which is always delivered from a light source 64 is detected by an optical sensor 65. When the ball 51 is pushed downward, a box 62 is also pushed down to cover the upper part of the sensor 65. Thus the detected light quantity is reduced at the upper part of the sensor 65, and the position of the ball 51 is known by the degree of reduction of said light quantity. Based on the position information on the ball 51, the shift speed of a cursor is changed on a screen. At the same time, shift control is possible for a 3-dimensional substance displayed on the screen. This enables a user to indicate more quickly an optional point on a screen than a case where a convertional pointing device is used.
