Title: Shim thickness measuring method for screw type pump
Inventor: MINEGISHI SEIICHI
IPC: F02B33/36
Filed: 1993-03-24
Abstract: PURPOSE:To perform reliable prevention of contact of a rotor with a cover body owing to thermal expansion of a rotor by a method wherein a given amount of a gap is ensured at the narrowmost part of a gap even when a gap between the end face of the rotor and the inner surface of the cover body is made uneven owing to a processing error. CONSTITUTION:A screw type supercharger is formed such that a rotor 2 contained in a housing 1 is supported to a bearing 4, attached to the cover body 3 of the housing, on a stepped shaft 5 protruded from the end face of the rotor. In the screw type supercharger, the thickness (t) of a shim 11 located between the stepped part 5c of the stepped shaft and the inner end face of the bearing is calculated from a hole depth L2 from the shaft length L1 of the large part 5b of the stepped shaft and the inner surface of the cover body to the inner end face of the bearing so that a given gap CL is ensured between the end face of the rotor and the end face of the cover body. The shaft length L1 is measured as an axial direction between the axial outermost spot of the end face of the rotor and the stepped part 5c and the hole depth is measured as an axial distance between the axial innermost sport of the inner surface of the cover body and the inner end face of the bearing.

Title: Gate circuit for inverter
Inventor: IIDA KATSUJI
IPC: H02M1/06
Filed: 1980-05-20
Abstract: PURPOSE:To reduce loss in case of turn-OFF when anode currents are small and prevent the lowering of efficiency by changing a capacitor of a gate circuit generating negative gate signals to a GTO in response to load currents. CONSTITUTION:When ignition signals are outputted to a gate G of a GTO51 and the GTO51 is ignited, currents are supplied to load through the GTO51 and the primary winding W1 of a current transformer 57 from a DC power source 50. Currents are induced in the secondary winding W21 of the current transformer 57 until the current transformer 57 is saturated, and a capacitor 54 is charged through a diode 55. When the voltage of the capacitor 54 reaches the prescribed value, the current transformer 57 is saturated magnetically, currents are not induced in the secondary winding W21, while the charge of the capacitor 54 is completed, discharge is prevented by means of the diode 55 and the voltage of the capacitor 54 is maintained. When a switch 53 for OFF is at ON, the stored charge of the capacitor 54 is discharged, and the GTO51 is turned-OFF. The same operation is also conducted to a GTO52.

Title: Sewn cloth conveying device
Inventor: OCHI MORIYA
IPC: B65G15/00
Filed: 1986-03-26
Abstract: PURPOSE:To improve adaptive ability to a kind and the shape of a substance to be sewn having a complicated shape and to improve the driving efficiency of an endless belt, by a method wherein the sewn cloth is conveyed by means of a pair of endless belts positioned at the front and the rear and driven at a synchronous speed. CONSTITUTION:Even if a sewn cloth 62', being long in a longitudinal direction, is placed across two belts 59 and 60, the two belts 59 and 60 are operated at the same speed since two driven pulleys 18 and 19 are synchronously rotated by means of a driven shaft 32, and the substance to be sewn is prevented from displacement and drop due to a speed difference during conveyance. The sewn cloth 62' is brought into contact with a perceiving plate 61, which is rotationally displaced to bring a normally closed microswitch 63 into an OFF-state to stop running of a motor 13 and rotation of the belts 59 and 60. By removing the sewn cloth 62' from the belts 59 and 60 by a worker, the perceiving plate 61 is self-restored to bring the normally closed microswitch 63 into an ON-state, and the belts 59 and 60 are re-operated. If a sewn cloth 62' is relatively rich in flexibility, by placing it only on the belt 59, conveyance, stop, reconveyance... can be effected.
