Title: Impact dot head
Inventor: TOKUNAGA MASAHIKO
IPC: B41J2/275
Filed: 1990-11-02
Abstract: PURPOSE:To improve durability and reliability of an armature by a method wherein, if, in an armature, the length of tapered portion thereof is taken to be L, the thickness of a junction between the armature and said portion to be T2, the thickness of a thin thickness T1, and the case depth of carburized layer D1, relationships therebetween are set as follows: L>2T1, T2>2T1, T2>3D1. CONSTITUTION:Since the case depth D1 of carburized layer is relatively smaller than the plate thickness T1 of a thin portion 6d, the value of T2 often depends on the value of T1. If L<T2 and T2<2T1, an armature fractures at its tapered portion in the region of scores of million strokes, whereas if L and T are larger than 9T1, durability of 2-300,000,000 strokes or more can be achieved. If L>2T1 and T2>2T1, the tapered portion of the armature 6 is not totally carburized even if there are deviations in the depth of carburized layer depending on the conditions of carburizing treatment. The surface of the armature 6 is entirely carburized as shown by oblique lines 6e and the thin portion 6b is totally carburized, whereas the portion 6d is partially carburized. As a result, anti-shock characteristics is improved, resulting in improved durability of the armature.

Abstract: PURPOSE:To prevent concentration to the peripheral section of a chip and a gold wire of stress from a molding resin, and to improve bond strength to defy peeling by forming irregularities and a slit to the surface of a passivation film. CONSTITUTION:Irregularities (h) are formed to the surface of a passivation film (b) protecting a chip (a), and the chip (a) is placed on a die pad (c). Outer leads (d) bring the chip (a) and the outside into contact electrically, and gold wires (e) connect the chip (a) to the leads (d). Even when stress is generated by the expansion and contraction of a molding resin (a molding package) (f) protecting the chip (a), the film (b), the die pad (c), the leads (d), the gold wires (e) and bonding pads (g), stress is dispersed by the irregularities (h) formed to the film (b). Accordingly, the concentration of stress to the peripheral section of the chip (a) and the gold wires (e) can be prevented while the bond strength of the resin (f) with the film (b) is improved, and both the resin (f) and the film (b) are difficult to be peeled.

Title: Partial cylinder supercharged engine
Inventor: YUZURIHA YASUHIRO
IPC: F02B33/00
Filed: 1985-12-27
Abstract: PURPOSE:To make stable driving performable in the way of equalizing the extent of suction negative pressure at the downstream of a throttle valve at the time of light load, by opening an on-off valve installed in an interconnecting passage interconnecting two suction passages at the throttle valve downstream at time of the light load. CONSTITUTION:At the time of medium or high load in an engine 1, the driving shafts of the engine 1 and a supercharger 4 are connected with each other, and supercharging to both cylinders 1a and 1b to be interconnected to a supercharging suction passage 2 takes place. An interconnecting passage 7 and a bypass passage 9 are closed by an on-off valve 6 and a relief valve 8. At the time of light load in the engine, these driving shafts of the engine 1 and the supercharger 4 are separated from each other so that no supercharging takes place. When suction pressure in a non-supercharging suction passage 3 at the downstream of a throttle valve 5b grows large, the relief valve 8 opens, and air is fed to a supercharging suction passage 2 at the downstream of the supercharger 4 from a bypass passage 9. Simultaneously with this, the on-off valve 6 opens, thus both these suction passages 2 and 3 at the downstream of these throttle valves 5a and 5b are interconnected to each other via an interconnecting passage 7.
