Title: Woodwind instrument
Inventor: MIYAZAWA TADASHI
IPC: G10D7/02
Filed: 1996-11-07
Abstract: PROBLEM TO BE SOLVED: To provide a woodwind instrument which ensures smooth key movement and desired playing even if friction, etc., are induced between an arbor and a key pipe by key operations. SOLUTION: This woodwind instrument to be blown by operating keys 6 or levers includes a main pipe 1, the arbor 10 which is installed approximately parallel along the outside wall of this main pipe 1, the key pipe 11 which is mounted with the keys 6 and the levers, is inserted into the arbor 10 and is turnable around the arbor 10 as a fulcrum, and annular recessed parts 15 which are disposed on the outer peripheral surface of the arbor 10 in its circumferential direction. Even if metallic powder is generated by the friction between the arbor 10 and the key pipe 11 by the key 6 operation, this metalic powder accumulates into the annular recessed parts 15 formed at the arbor 10. Even if the arbor 10 is delicately expanded to a larger diameter by the driving of knock pins, etc., the parts increased in the diameter are limited to the annular recessed parts 15 alone.  The trouble in playing by the generation of the metallic powder and the increased diameter of the arbor is thus prevented while the arbor 10 and the key pipe 11 are maintained in the desired tight contact state.

Title: Starting fuel supply system for engine
Inventor: ARAKI SATORU
IPC: F02M1/16
Filed: 1989-11-30
Abstract: PURPOSE:To supply fuel necessary for engine starting easily and accurately by setting up a manual priming pump in an auxiliary passage leading to a filter element in an air box from a constant fuel chamber in a carburetor. CONSTITUTION:When a pumping member 32 of a priming pump 31 is pressed by a finger tip in a repeative manner and thereby a constant fuel chamber 22 is turned to negative pressure inside, fuel in a tank 13 is drawn in by way of a pump 21. Simultaneously a diaphragm 24 is pulled toward the constant fuel chamber 22 and fuel valve 27 is opened, so that sufficient excess fuel is stored in this chamber. In addition, this excess fuel arrives at a discharge passage 37 by way of a pump case 34. On the other hand, when an engine is started and negative pressure occurs in an intake passage 5, fuel in the constant fuel chamber 22 is drawn out to a venturi 3 from a main nozzle 16. At this time, since any negative pressure will not work on an auxiliary passage 39 consisting of these passages 35, 37, fuel in the constant fuel chamber 22 can be prevented from being drawn out to an air box 7.

Abstract: PURPOSE:To satisfactorily joint hot steel materials at high speed by pressure welding while scarfing by blowing oxygen to a butted part as a preceding steel material and the following steel material are pressed to each other after the hot steel materials are mutually butted. CONSTITUTION:The preceding steel material 1 and following steel material 2 are preliminarily butted and pressed to each other, so, by blowing oxygen with a torch 6 to the butted faces between which scale is held, the part in which scale is present is scarfed. That is, this stage is the stage where scarfing with oxygen jet is executed. To keep the descaling effect in this stage, it is preferable to execute oxygen scarfing in a non-oxidizing atmospere. It is better to take it as reducing flame atmosphere using direct-fire reducing burners 7 when preheating or heating is executed. In this way, the hot steel materials are satisfactorily joined and it is executed with a simple equipment regardless of the thickness of scale in the joining surfaces.
