Title: Suction system for engine
Inventor: TAKAHASHI KOICHI
IPC: F02B31/00
Filed: 1986-09-19
Abstract: PURPOSE:To control a torque shock, by opening an on-off valve in a main suction passage at the time of decelerating drive, while closing this valve by degrees at the time of returning to stationary drive. CONSTITUTION:An on-off valve 7 is installed in a main suction passage 2. An auxiliary air passage 17 bypassing this on-off valve 7 is installed as well. At the time of decelerating drive of an engine, this on-off valve 7 is opened even if it is a full close range of the valve 7. And, at the time of returning to stationary drive, this on-off valve 7 is gradually closed. According to this method, a combustion state is preventable from going to a sudden change even in case of transition from a deceleration driving state to a stationary driving state, so that a torque shock is restrained from occurring.

Abstract: PURPOSE:To perform bonding without processing of a semiconductor element and to manufacture a film carrier, by forming protruded parts at the tip parts of a plurality of leads, which are extended and formed to the opening parts of a flexible insulating film by a heating means. CONSTITUTION:A metal foil 4 is laminated so as to avoid sprocket holes 2 on a flexible insulating film 1. Thereafter heating is performed and a bonding agent 3 is hardened. As the metal foil 4, e.g., copper, copper alloy such as Be-Cu and the like are used. Then, the metal foil 4 is machined through a photolithography process and an etching process. Thus fingers 5 are formed. Then, layer light is projected on the tip part of each finger 5. After the melting point is reached at the tip part of the finger 5, on which the laser light is projected, a small ball is formed at the tip due to surface tension. The ball is gradually cooled. Thus a downward dropping shape is obtained, and a semispherical shape, a tear drop shape and the like are formed. A film carrier has the fingers 5 having the protruded parts 6, which are formed in this way. Tin or nickel is plated as a basis, and gold is plated thereon. Thus the film carrier with bumps is formed.

Title: Photosemiconductor device
Inventor: OUCHI HIROBUMI
IPC: H01L31/107
Filed: 1985-10-09
Abstract: PURPOSE:To prevent a dark current from increasing due to tunneling current by forming one conductivity type fourth region having impurity density larger than that of the first region in the first region. CONSTITUTION:A junction is formed between the first region 15 and the second region 16, and one conductivity type fourth region 25 having larger impurity density than the region 15 is formed in the region 15. An incident light of 1-1.6mum of wavelength passes the regions 15 and 25 to be absorbed to one or both of a region 14 and an N-type InGaAs layer 13. Since reverse bias voltages are applied to electrodes 19, 20, N-type InGaAs layer 13 and the region 14 are depleted, photovoltaic carrier is moved to the main junction region of a junction 26 being applied with sufficiently high electric field to cause an avalanche multiplication at a drifting speed. Here, the avalanche multiplication occurs by the input carrier and the multiplied photocurrent flows to an external circuit connected with electrodes 19, 20.

Abstract: PURPOSE:To enable completion of combustion by facilitation of mixing even in the case of low air ratio combustion and thereby to improve thermal efficiency, by providing a burner on one side of a combustion chamber and by disposing also a facilitating means of mixing of a combustion gas on the other side of the chamber at a prescribed distance from the burner. CONSTITUTION:A burner 2 is provided on one side of a combustion chamber 1, while a facilitating means 3 of mixing is disposed on the other side of the chamber at a prescribed distance from the burner 2. The mixing means 3 is constructed, for instance, of rod-shaped bodies 4 having arbitrarily-shaped sections and so provided as to pierce the combustion chamber 1 through. While a flame 8 is generated by the burner 2, air for combustion is introduced into the combustion chamber 1 and the combustion is started. At this time, a combustion reaction is facilitated by generating a turbulent flow in a combustion gas by the mixing facilitating means 3. For instance, a bluff-body effect is made to act for each of the rod-shaped bodies 4 and thereby a vortex flow is generated on the downstream side of each rod-shaped body 4. Thereby the combustion can be completed even in the case of low air ratio combustion.
