Title: Operation lever grip adjusting mechanism for handlebar vehicle
Inventor: HATAGOSHI GENICHI
IPC: B62L3/02
Filed: 2000-08-30
Abstract: PROBLEM TO BE SOLVED: To prevent excessive change of a space between a grip and an operation lever to an unexpected level by a rider in the operation lever for a handlebar vehicle with a grip adjusting mechanism. SOLUTION: A turn regulating means 27 is composed of a fixed protrusion piece 12i on a lever main body 12 and a movable protrusion piece 23g on a seat plate 23d. When an adjuster pin 23 turns in a pin hole 22, the movable protrusion piece 23g abuts on the fixed protrusion piece 12i at one end or the other end thereof to regulate the turn of the adjuster pin 23 within one turn. At abutting of the movable protrusion 23g on the one end of the fixed protrusion piece 12i, a cam face 23f-1 which has a longest distance from a center axle of the adjuster pin 23 is allowed to face abut on a cam abutting face 13d on a knocker 13, and at abutting of the movable protrusion 23g with the other end of the fixed protrusion piece 12i, a cam face 23f-5 which has a shortest distance from the center axle of the adjuster pin 23 is allowed to abut on the cam abutting face 13d of the knocker 13.  Thus, the cam face 23f-1 for the maximum grip and the cam face 23f-5 for the minimum grip which are adjacently located do not abut on the cam abutting face 13d successively.

Title: Cleaning method for inside surface of conduit line
Inventor: KOMATSU HIROSAKU
IPC: B08B3/10
Filed: 2000-09-01
Abstract: PROBLEM TO BE SOLVED: To provide a cleaning method for the inside surface of a conduit line, the method being advantageous in terms of time and cost since the inside surface can be efficiently cleaned thereby with a gas-liquid mixture fluid without causing a loss while reducing the consumption of a liquid detergent.

IPC: F16C29/08
Filed: 2000-09-19
Abstract: PROBLEM TO BE SOLVED: To provide a sealing device for a linear guide capable of securing the required sealing performance over the entire area of a lip part. SOLUTION: A cross-sectional shape along the moving direction S of a slider is changed only for the lip part 8 which seals an approximately semicircular ball groove provided on a side face of a guide rail, so that the pressure of contact of the lip part 8 is adjusted to become relatively high. That is, for the lip part 8 making contact with the upper half of the ball groove 1c, the end of the lip part 8 making contact with the upper half of the ball groove is set to have an arc with a greater radius than the arc of the end of the lip part 8 making contact with the lower half of the ball groove, as seen from the moving direction S of the slider (longitudinal direction of the guide rail).  Thus, decreases in the sealability of the lower contact portion of the ball groove on the side face of the guide rail and in the sealability of the upper surface of the guide rail are prevented at the same time.

Inventor: OKUBO KATSUYUKI
IPC: B29C39/02
Filed: 2000-09-22
Abstract: PROBLEM TO BE SOLVED: To provide a method and a mold for molding an optical element with high accuracy by guiding a sink to a transfer surface not requiring high transfer accuracy to suppress the generation of the sink in a transfer surface requiring high transfer accuracy, and the optical element. SOLUTION: When the optical element is molded from a photosetting resin 5 using the mold 1 for molding the optical element, the transfer surface 2a of the mold part 2 of the mold 1 for molding the optical element is coated with the uncured photosetting resin 5. Low adhesion treatment is applied to the transfer surface 2a of the mold part 2 so that an optically unnecessary region transfer region Ao becomes low in the adhesion with the photosetting resin 5 as compared with an optically effective region transfer region Ai.  Therefore, when the photosetting resin 5 is irradiated with necessary ultraviolet rays through a light pervious material 4, a sink is preferentially generated from the optically unnecessary reaction transfer region Ao low in the adhesion with the photosetting resin 5 by the shrinkage of the photosetting resin 5 accompanied by curing and the generation of the sink in the optically effective region transfer region Ai requiring transfer accuracy can be prevented. As a result, the optical element can be manufactured with extremly high accuracy.
