Title: Method for preventing teaching box for welding robot from electrostatic noise
Inventor: YAMAGUCHI TOORU
IPC: B25J9/22
Filed: 1984-06-26
Abstract: PURPOSE:To prevent a teaching box from malfunction due to electrostatic noise by connecting the case of the teaching box to a shielding wire for a control cable through a capacitor to earth the teaching box. CONSTITUTION:The case 1 of the teaching box for a welding box is earthed through a lead wire of the shielding wire 5 for the control cable 3. In this case, the case 1 is connected to the shielding wire 5 through a parallel body consisting of the capacitor C and a resistor R.

Title: Oxide semiconductor for thermistor
Inventor: OKAMOTO KAORI
IPC: C04B35/00
Filed: 1987-05-28
Abstract: PURPOSE:To lower resistivity, and to increase a B constant by composing an oxide semiconductor for a thermistor of the sintered mixture of a metallic oxide and containing five kinds of cobalt, copper, lithium, nickel and silicon at a specific rate as constituent metallic elements for the sintered mixture. CONSTITUTION:An oxide semiconductor for a thermistor consists of the sintered mixture of a metallic oxide, and five kinds of 69.0-96.0 atom % cobalt (CO), 0.4-5.0 atom % copper (Cu), 2.5-22.0 atom % lithium (Li), 0.5-5.5 atom % nickel (Ni) and 0.0-2.5 atom % silicon (Si) (where except 0.0 atom %) are contained at 100 atom % in total as metallic elements for the sintered mixture. Consequently, the oxide semiconductor for the thermistor having low resistivity in a region 1 and a high B constant can be acquired. Cobalt oxide (CoO) is used as a basic composition in the semiconductor, and the high B constant can not be attained by the contribution of hopping conduction when tricobalt tetraoxide (Co3O4) is formed.

Title: Explosive cladding method of metal
Inventor: TAKAMURA MASAYUKI
IPC: B23K20/08
Filed: 1980-09-24
Abstract: PURPOSE: To control the velocity of explosion and suppress the formation of an intermetallic compound and an excessive alloy layer by making the quantity of explosives more on the initiation point side and less on the end point side.  
     CONSTITUTION: The quantity of distribution of explosives 2 may be changed linearly, curvedly or stepwise and is properly changed according to the quantity of explosives, the quality of explosives, and the metallic materials to be clad. When the explosives are exploded by igniting a detonator 1, an inside pipe 3 and outside pipe 4 collide at high velocity and stick by pressure. Since the quantity of distribution of the explosives 2 is made more on the initiation point side and less on the end point side, an increase in the velocity of explosion higher than required on the end point side does not occur. Therefore, the formation of an intermetallic compound and an excessive alloy layer is suppressed, and the metal clad body of high press sticking strength and good plastic workability is obtained.

Title: Constructing method for cast-in-place concrete pile
Inventor: KANAI SOUJI
IPC: E02D5/34
Filed: 1981-08-27
Abstract: PURPOSE:To improve a constructing work of an underwater pile, by a method wherein the inside of a stand pipe inserted into the ground is excavated, and after a reinforcing rod cage, which has a steel frame mating the pile head, is inserted, concrete is placed, and it is caused to overflow the steel frame. CONSTITUTION:The inside of a stand pipe A inserted into an underwater ground is excavated to insert a pipe into a ground, and a reinforcing rod cage D, whereto a cylindrical steel frame C with the same diameter as that of a foundation pile is monolithically attached to a pile head, is inserted. The pipe is lifted as underwater concrete 6 is deposited through a tremie pipe E. After the concrete, being levelled up, enters the inside of the cylindrical steel frame C through a stopper 5 with brim, the concrete is levelled up to drop into a gap F after overflowing the steel frame. Thus, concrete at a pile head part, deteriorating in quality, is discharged into the gap F, and this makes the quality of the concrete of the pile head part uniform with that of the concrete of the pile body positioned under the level of the pile head part.

IPC: B60T11/20
Filed: 1979-10-16
Abstract: PURPOSE: To reduce the pedal stroke and a treading force therefor by a method wherein a discharging quantity of fluid with respect to a moving amount of a piston is increased at an initial stage of a brake operation and the same is decreased at a later stage thereof.  
     CONSTITUTION: Pistons 7, 9 are moved to the left and pressures in respective chambers begin to increase due to a brake operation. In this case, a pressure increase of the chamber 10 is larger than that of the chamber 11, therefore, liquid in the chamber 10 is flowed into the chamber 11 and is fed into a hydraulic pressure actuator through a withdrawal port 28. When the hydraulic pressure in the chamber 10 reaches a predetermined value, a piston 34 is moved to the right against a spring 38 and the liquid in the chamber 10 is fed into a chamber 35 through a hole 36. Accordingly, the pressure in the chamber 10 is not increased so much even though the piston 7 is moved to the left continuously while only the pressure in the chamber 11 is increased. When the brake is released, the pistons 7, 9 begin to return and the liquid in the chamber 35 returns to the chamber 10, however, the liquid corresponding to a quantity which has flowed into the chamber 11 is short, by that amount, therefore, the pressure of the chamber 10 becomes negative. A valve 25 is opened due to this negative pressure and the liquid is supplemented into the chamber 10.
