Title: Shoe-plate structure for tractor
Inventor: KOTABE KISABUROU
IPC: B62D55/22
Filed: 1981-01-16
Abstract: PURPOSE:To reduce noise and improve durability by installing spring members so that the springy force of the spring member serves to reduce the load onto a stamping plate. CONSTITUTION:A spring member 14 is joined integrally through seisure on the back surface of an elastic shoe plate 1 namely on the installation surface onto a truck link 15. The spring member 14 is set so that a springy force acts in the direction for reducing the load applied onto the elastic stamping plate 1. The repetive load applied onto the elastic shoe plate 1 during a tractor travels is sharply reduced by the synergistic effect of the springy action of the shoe plate and the springy action of the spring member 14. Thus, the fatigue of the elastic stamping plate 1 in the composite structure with the spring member due to repeative load is reduced, and elastic performance can be developed sufficiently, and crack is hardly generatd even through repeated stamping for stones etc., and durability can be improved.

Title: Ni alloy for cast denture base
Inventor: NAKANO KAZUYUKI
IPC: A61K6/04
Filed: 1980-01-17
Abstract: PURPOSE:To provide an Ni alloy for a cast denture base having a lower m.p. and slightly moderated strength and enabling casting with a gypsum filler by adding a specified amount of Co, Cr, Mo, W, Cu, Si and C to Ni. CONSTITUTION:This Ni alloy consists of 3-42% Co, 5-30% Cr, 2-18% Mo, 0-10% W, 0-10% Cu, 0.1-3% Si, 0.01-0.5% C and the balance Ni and inevitable impurities.

Title: Electropneumatic positioner
Inventor: KIMURA ATSUSHI
IPC: G01B7/30
Filed: 1992-01-14
Abstract: PURPOSE:To transmit the opening degree of a valve to a controller in the stable manner even when the distance between the air regulating valve and the controller is changed by dividing a current signal corresponding to the opening degree of the valve and outputting the divided signal as a current signal. CONSTITUTION:A constant Zener voltage VZI is generated at both ends of a Zener diode DZI constituted of a part of current signals I2 entering an output transmitting circuit 42. Since the divided voltage at the inverting input terminal (-) of an operational amplifier Q1 is held constant, the internal resistance of a transistor Q2 is changed so that the voltage of a moving element of an impedance variable device IV changed by a transmission shaft SH is agreed with the divided voltage, thereby to change a current signal I3. If resistance R1-R5 and the resistance RIV of the whole device IV are selected to assume a specific relationship, a specific formula is held among the signal I3, ratio alphaof the divided voltages, the resistance R5 and the voltage VZI. The signal I3 is changed in proportion to the ratio alpha. Therefore, the signal proportional to the opening degree of the valve is sent to a detecting resistance 32, and a controller 30 detects the opening degree of the valve as a voltage V0 proportional to the opening degree of the valve.

Abstract: PURPOSE:To make it unnecessary to frequently perform the changing operation of a picture reading scanning mode by providing an operating means for changing the picture reading scanning mode preferentially set by a control means to the other picture reading scanning mode. CONSTITUTION:In a facsimile equipment F, as picture reading scanning modes, respective modes, for example, normal, fine, super-fine, and halftone are selectably set in this order. In this case, when a user uses the fine mode more frequently than the normal mode, the fine mode is selected and registered as the mode to be preferentially set by operating the specific key operation of an operating part 6. At the time of executing, for instance, facsimile transmission after such registration is ended, when the reading scanning of an original picture is operated by a picture reading part 8 of the facsimile equipment F, the fine mode is preferentially set.
