Title: Premixed stratified air supply two cycle engine
Inventor: MATSUURA MASAAKI
IPC: F02B75/18
Filed: 1992-02-04
Abstract: PURPOSE:To prevent a rich mixture from escaping to the outside from an exhaust port before combustion by shutting off flow of rich mixture which flow into a combustion chamber from a second scavenging port toward the exhaust port side by scavenging air stream of rich mixture which flows into the combustion chamber from a first scavenging port. CONSTITUTION:Two cylinders 2, 3 perform combustion simultaneously in an engine, and a lean mixture from a crank chamber S1 and a rich mixture from a crank chamber S2 flow into combustion chambers S3, S4 simultaneously. A first scavenging port 15 is positioned between a second scavenging port 16 and an exhaust port 17 and directed toward the cylinder head 12 side. Scavenging air stream of the lean mixture which flows into the combustion chamber S3 (S4) from the first scavenging port 15 is injected before the rich mixture which flows in from the second scavenging port 16 to prevent the rich mixture from flowing into the exhaust port 17 side. Thus, it is possible to prevent the rich mixture from escaping to the outside from exhaust port 17 before combustion and improve output power and fuel efficiency.

Title: Sputter target and abrasion resistant film as well as thermal head, which are utilizing it
Inventor: ISHIGAMI TAKASHI
IPC: B41J2/335
Filed: 1990-02-28
Abstract: PURPOSE:To obtain stable sputter target by a method wherein the sputter target is constituted of a material containing the predetermined amount of at least one kind (excluding a case in which only zirconium oxide is contained) selected from titanium oxide, zirconium oxide and hafnium oxide and a balance is silicon oxide substantially. CONSTITUTION:The oxide of IVa group metal of Ti, Zr and Hf, which are contained in silicon nitride sputter target, improves the toughness of a sputter film obtained and increases the stability of composition of the target itself whereby a sputter rate is improved and the deterioration of the sputter rate due to the kind of sputter gas is prevented. The content of the sputter target is preferably within the range of 1mol%-40mol% as the total amount of oxide of the IVa group metal. When the content of the oxide of IVa group metal is less than 1mol%, the strength of an obtained sputter film is not sufficient while the content of the same exceeds 40mol%, the IVa group metal is readily separated out as a metallic constituent and there is possibility to invite the deterioration of the insulating property of the sputter film. One kind or more than two kinds of the oxides of the IVa group metal can be used by mixing them; however, the independent use of zirconium oxide should be excluded.

Filed: 1987-03-03
Abstract: PURPOSE:To manufacture a metal clad plate of high peeling off strength simply with good efficiency online by sticking a medium to the superposing face of base metals or clad materials by thermal spraying and rolling this medium by interposing it between the base metal and clad material. CONSTITUTION:The medium of Ni, Cu, etc., is rolled by interposing between the base metal of Al alloy, Ti alloy, etc., and the cladding material of stainless steel, Ti, etc., to obtain a clad metal plate.

Title: Brake fluid pressure control device
Inventor: HIRAIWA KAZUMI
IPC: B60T8/30
Filed: 1993-03-10
Abstract: PURPOSE:To prevent the occurrence of overshoot, and thereby enhance braking performance by providing a decompression control mechanism, changing the tension of a valve spring, and thereby providing a control plunger the stroke of which is restricted based on the positions of a suspension member and the like. CONSTITUTION:A sensor lever 14 is rocked by the rocking motion of a control plunger 9, so that the lever is brought into contact with a suspension member 20. Namely, if a loading capacity is large, the suspension member 20 is in a high position, the sensor lever 14 is thereby rocked in a large way, and a valve spring 17 is imparted with high tension, so that a hydraulic pressure hold point becomes high. When a loading capacity is small, the hydraulic pressure hold point is low, the sensor lever 14 is rocked only when brake hydraulic pressure is operated. No sensor lever 14 is operated at all at the time of normal running. This constitution thereby allows members between the control plunger 9 and the suspension member 20 to be enhanced in durability and reliability, and also enhances the degree of freedom in design.
