Title: Powder applying method and device therefor
Inventor: ARAI JIYUUSAKU
IPC: B05C19/00
Filed: 1981-02-26
Abstract: PURPOSE: To omit collecting work for scattered powder, in a method of applying powder onto the surface of a workpiece, by inclining the workpiece in a manner such that its surface coated with a binder is placed upside, and letting the powder flow downwards along said surface to adhere to said surface.  
     CONSTITUTION: A binder B is sprayed onto a panel workpiece A, and the panel workpiece A is clamped inside the central chamber 4a of a tray 4 by position- control of partition plates 8. On the other hand, powder C is reserved in a vacant chamber 4b. When the tray 4 is inclined, the powder C in the vacant chamber 4b flows downwards beyond the partition plate 8 through the panel surface into the other vacant chamber 4c. During its passage, the powder C is successively bonded to the panel surface by the viscosity of the gelling binder 8, so that the whole surface of the binder-applied panel is coated with the  powder C. Thereafter, the panel A is taken out, and a top-coat binder D is sprayed, baked and fixed o the surface of the panel A. Thus, a product is obtained. Consequently, the collecting work for powder can be omitted, and a uniform layer coated with powder can be formed.

Title: Gear pump with proper gear truck depth and length
Inventor: TERUYAMA HIDEO
IPC: F04C2/18
Filed: 1979-03-09
Abstract: PURPOSE: To prevent the leakage of oil by securing proper truck depth by more shortening the central interval of gear hole than that of bearing hole.  
     CONSTITUTION: The center Oe of the gear hole is deviated toward the center O' of the other bearing hole against the center O of the bearing hole; that is, the interval between the centers Oe and Oe' of both gear holes is made shorter than that between the centers O and O' of the bearing holes. When driving the said pump, because the center of the gear shaft is deviated toward Os, the relation between the gear hole centered at Oe and the addendum circle (a) of the gears 2 and 3 forms a gear truck having the depth (t) in the range of rotation angle θe. Thus, the leakage of high-pressure oil from the addendum of the gear can be exactly prevented.

Filed: 1997-02-12
Abstract: PROBLEM TO BE SOLVED: To accelerate heat conduction and improve response, by inserting material for accelerating heat conduction into the part between a sheath accommodating a thermocouple and a well for protecting the sheath from outside. SOLUTION: Material 20 for accelerating heat conduction is inserted into a gap between a sheath 4 and a well 5. Low melting point metal whose coefficient of volume expansion at the time of solid is approximate to that at the time of liquid is preferably used as the material 20. When an object 17 of temperature measurement in a structure body 10 for the object, like a fluid tube, is fused metal or the like, it is desirable that the material 20 is metal of the same kind as the object 17. By inserting the material 20 for accelerating heat conduction, the temperature of a junction point (junction point for temperature measurement) in the seath 4 is changed by the heat traveling from the side surface of the well 5 through the material 20 and the sheath 4. The response can be improved as the result that the heat conduction path is minimized.
