Title: Ultrasonic probe
Inventor: TANPO MAKOTO
IPC: A61B8/12
Filed: 1999-08-04
Abstract: PROBLEM TO BE SOLVED: To easily wash and sterilize a probe body and an insertion path part of an ultrasonic probe consisting of a clamping part, the insertion path part and an ultrasonic sensor by providing the probe with a freely attachable and detachable treatment implement to the insertion path part. SOLUTION: A semicircular groove 10 is formed along the longitudinal direction of the circumferential flank of the insertion path part 61 consisting of a metallic pipe inserted with a cable 63. The diameter of a pipe made of a resin is formed to a slightly larger than that of the groove 10 and the length thereof to approximately the same as that of the groove 10. When the pipe is mounted at the groove 10 of the main body, the pipe is fitted into the groove 10 from its circumferential flank by utilizing the elasticity of the pipe itself. At this time, the groove 10 and the pipe are so arranged and formed that the ultrasonic scanning sectional axis by the ultrasonic sensor 62 and the central axis of the pipe are aligned.  When the main body of the ultrasonic probe is washed and sterilized after operation, the pipe is removed from the groove 10 and is discarded and the main body and its groove 10 are washed and sterilized.

Title: Multistage sprocket device for bicycle
Inventor: NAGANO MASASHI
IPC: B62M9/10
Filed: 1991-09-02
Abstract: PURPOSE:To facilitate unhooking of a chain from a replacement assisting protrusion and to prevent the chain from moving over the addendum of the tooth of a large sprocket, in a multistage sprocket for a bicycle having the replacement assisting protrusion to assist transfer of the chain from a small sprocket to the large sprocket. CONSTITUTION:A guide surface 15a' to guide the outer side of a link plate 3b of a chain 3 is formed on a second tooth 15a surface. A replacement assisting protrusion 16 is displaced in the direction of a small sprocket 12 so that the replacement assisting protrusion is engaged with the chain 3 in a position spaced away from a position, where the protrusion is engaged with a first tooth 15c, by a distance approximately an integral number times as long as the peripheral pitch of teeth. A slope where the more it is situated nearer the deddendum side, the more it approaches the large sprocket 13 side is formed to the side on the large sprocket 13 side of the replacement assisting protrusion 16. By bringing the guide surface 15a' into contact with a chain part transferred together with the slope 16a, the chain 3 is prevented from deeply cutting through the replacement assisting protrusion 16.

Title: Material reinforced against thermal stress
Inventor: TANAKA NOBUHIKO
IPC: C22C47/00
Filed: 1985-10-07
Abstract: PURPOSE:To assure the soundness of a constituting material by embedding core materials having the coefft. of thermal expansion different from the coefft. of thermal expansion of the matrix metal of a metallic material for structural purpose made into a specified shape having structructurally discontinuous parts into said metallic material so that the boundary exfoliation and contact of the matrix metal and the core material are made possible by corresponding to temp. changes. CONSTITUTION:Plural pieces of core wires 14 are embedded into the connecting part 13 between a joint body 11 and a collar part 12. The core wires 4 are made of a different material having the coefft. of thermal expansion smaller than the coefft. of thermal expansion of the matrix material constituting the joint body 11. The apparent heat capacity is consequently largest with the constituting material I heated to the prescribed temp. at which the joint body 11 and the core wires 11 make boundary contact with each other. The coefft.of thermal expansion of the core wires 1 is smaller than the coefft. of thermal expansion of the joint body 11 and therefore,when the temp. on both inside peripheral sides of the joint body 11 is quickly increased by fluid, etc., flowing in the joint body 11, the joint body 11 induces the larger thermal shrinkage than the core wries 14 and the gap by the boundary exfoliation is formed. The apparent heat capacity of the joint body 11 is thus made smaller and the heat conductivity from the joint body 11 to the collar part 12 is improved.

Title: Fuel atomizing device
Inventor: MASAI TADAHISA
IPC: F23D11/38
Filed: 1986-09-22
Abstract: PURPOSE:To sufficiently convert pressure energy of steam, being a spray medium into speed energy, by a method wherein a blow hole is formed in the shape of a divergent nozzle, and steam is expanded until a velocity of flow at the outlet of a steam hole is increased to a supersonic speed. CONSTITUTION:A steam hole 11 is formed in the shape of a divergent nozzle where the area of a steam hole outlet 13 is increased over that of a steam hole inlet 12. The steam hole inlet 12 communicates to a steam passage 3 of a body 2, through which high pressure steam is fed, the steam hole outlet 13 is connected to a joint hole 6 on the upper stream side of a liquid fuel hole 9, and a continuous flow passage, where there is almost no change in a section area, is formed extending from the steam hole outlet 13 to the joint hole 6. The area ratio between inlet and outlet and the hole gradient of a steam hole 11 are decided to an optimum value, at which an energy loss is minimized, according to an expansion condition, i.e. steam pressure at inlet and outlet. High pressure steam fed to the steam inlet 12 is expanded until its speed at the steam hole outlet 13 attains a supersonic speed, and since an increase in a steam momentum is prevented from occurring and an energy loss due to sudden expansion of steam after passage of it through a steam hole is prevented from being incurred, fuel spray characteristics are improved.
