IPC: B66F9/14
Filed: 1998-01-16
Abstract: PROBLEM TO BE SOLVED: To compactly house the horizontal part of a fork projected out to the forward part of a car body. SOLUTION: A fork 5 is divided into a vertical rise part 6 and a horizontal part 7. In order to connect the rise part 6 with the horizontal part in such a way as to be freely engaged/disengaged therewith, projected parts 20 are projected out of both the sides at the lower end part of the rise part 6 so as to allow the projected parts 20 to be fitted with the recessed groove 21 of each projected part 22 projected out of both the sides at the base part of the horizontal part 6. Cut-out parts through which the projected parts 22 are inserted, are provided for a mounting frame 4 guiding the rise part 6 in such a way as to be freely slid, and when the fork 5 is to be housed in, the fork 5 is brought up to the innermost side, so that each projected part 22 is thereby joined with each cut-out part.  At this time, the insertion part 32 of a pull-in stem 31 located at the side of a car body 1, is inserted into the insertion hole 33 of the horizontal part 7, so that the horizontal part 7 can thereby be compactly housed in the inner side of the car body 1 by letting the horizontal part 7 be pulled in by means of a hydraulic cylinder 30.

Abstract: PURPOSE: To taper an opening and prevent the snapping of metal wiring provided in the opening, by combining an oxidizer with silazane and performing surface treatment when making the opening in an insulating film on a semiconductor substrate provided with a diffused region.  
     CONSTITUTION: An oxide film 13 is coated on a p-type Si substrate 11 and provided with an opening to produce an n + -type region 12 by diffusion. At that time, a PSG film 14 is also produced. The substrate 11 is dipped in a mixed liquid containing a hydrogen peroxide solution and aqueous ammonia. As a result, the film 14 on the region 12 is removed and the film 14 on the oxide film 13 is changed into a film 14a of small thickness. A mask 15 made of a photoresist film and having an opening is provided on the film 14a. Hexamethyldisilazane treatment is effected to raise and stabilize the adhesive power between the film 14a and the mask 15. A hole is opened through the exposed film 14 and then through the film 13. Etching is effected by an ammonium fluoride mixed liquid to provide the film 13 with an opening which has a small angle θ 12  approximate to that θ 11  of the opening over the resion 12.

Title: Atmospheric pressure adjusting device for carburetor
Inventor: SAKURAI SHIYOUICHIROU
IPC: F02M7/28
Filed: 1979-01-26
Abstract: PURPOSE: To prevent the mixture ratio from becoming thin at the time of high load by the method wherein the intake port of the air to be sent to the carburetor fuel system is opened in the down stream of the large venturi unit and the choke valve, and the intermediate part and the air valve chamber of the atmospheric pressure adjusting device are connected.  
     CONSTITUTION: When the load of the engine becomes large and the load is increased by the air flow in large venturi unit 9, air flows from air intake 11W10. By this, the negative pressure in path 12 which is determined by orifices 13 and 14 is drawn into air valve chamber 16. In high altitudes terrain, air valve 24 is opened by a proper amount by the expansion of bellows 18. On the other hand, negative pressure is produced in main nozzle part 2, and due to the pressure difference of air valve chamber 16, the air required for adjusting the air-fuel ratio is supplied to main well 5. Consequently, at the time of high load operation, the negative pressure inside air valve chamber 16 becomes large and the pressure difference with respect to main nozzle 2 becomes small. As a result, the amount of air flowing into main well 5 becomes small, and the mixture ratio is prevented from becoming thin.
