Title: Method and device for heat treatment of weld zone of double pipe
Inventor: NAKAMURA HITOSHI
IPC: C21D9/50
Filed: 1986-09-17
Abstract: PURPOSE:To improve the residual stress in the weld zone of a double pipe by heating the part near the weld zone of the inside and outside pipes from the inside in a gaseous atmosphere, then cooling the pipes with cooling fluid from the inside and outside to generate the tensile stress in excess of the yield point, then cooling the pipes. CONSTITUTION:The end of the outside pipe 2 installed to a bottom 1 of a vessel and the surface of the inside pipe 3 inserted into the outside pipe 2 are welded. The inside and outside surfaces of such double pipe are held in the gaseous atmosphere. A moving body 5 provided with an internal cooler 7, an external cooler 9 and a heater 6 is then inserted into the inside pipe 3 and the heater 6 is positioned near the weld zone 4 to heat said zone so that the outside pipe 2 is heated through the weld zone 4. The heating is stopped upon heating to a prescribed temp. and the moving body 5 is so raised as to project the external cooler 9 from an aperture 8 of the inside pipe 3. The cooling fluid is ejected from the internal and external coolers 7, 9. The tensile stress in excess of the yield point is generated near the weld zone during the course of such cooling and elongation is generated in said part by the plastic deformation. The double pipe is held imparted with the residual compressive stress after the completion of the cooling.

Title: Simple test method for trouble detecting circuit
Inventor: MARUYAMA YOSHIHARU
IPC: G06F11/22
Filed: 1987-09-01
Abstract: PURPOSE:To inspect the working of a trouble detecting circuit with a PROM containing the written firmware packed into a device, by preparing an instruction in a program language to produce a pseudo trouble to the device itself. CONSTITUTION:An odd or even parity is produced from firmware and another parity is obtained from the data which is called out of a parity ROM concurrently when a CPU reads a PROM. Then the occurrence of an error is decided when no coincidence is obtained between both parity data. When a parity error is produced intentionally, a parity is inverted to the data on a specific area which is not used by the firmware and the data on said specific area is read out. Then a process where a data area where an inverted parity is written is read out is prepared in a program language as one of instructions. Thus it is possible to perform a hardware test in a state where a prom containing the written firmware is packed into a device.

Title: Hydraulic power transmission joint
Inventor: SUZUKI SATORU
IPC: F16D31/02
Filed: 1988-09-01
Abstract: PURPOSE:To obtain larger torque as a rotation speed difference becomes larger by providing a rotary valve with an orifice, which is located in the opening portion of a discharge passage and successively varies the opening area of the discharge passage due to its rotation. CONSTITUTION:When a rotation difference is generated between a cam ring 11 and a rotor 12, a plunger 15 in its discharge stroke is pushed toward the center of a shaft by the cam ring 11. Then the plunger 15 pushes out oil within a plunger chamber 14 toward a main passage through the orifice 21A of a rotary valve 21, and an intake valve 20 closes an intake passage 18. At this time, as hydraulic pressure is generated in the plunger chamber due to the resistance of the orifice, the reaction force of the plunger arises. Torque is generated by rotating the cam ring 11 against the reaction force of the plunger. Consequently, larger torque can be obtained successively in such a using condition that a differential rotation is large.

Title: Cartridge container
Inventor: SHOJI IWAO
IPC: B41F31/02
Filed: 1987-09-02
Abstract: PURPOSE:To take out viscous object in a container without waste, by making it possible to tuck in the container's upper half section, which is made of a flexible sheet material, in such a manner that the upper half section contacts the inner wall of the container's lower half section, on which a fill/drain port is equipped. CONSTITUTION:When the content has been thoroughly taken out by suction from a fill/drain port 3, a container's upper half section 1B, because of its flexibility, is tucked in a container's lower half section 1A in such a manner that the upper half section 1B contacts the inner wall of the lower half section 1A under an inside out condition. Under this tucked in condition, the upper half section 1B does not give total face contact with the lower half section 1A, and a space is formed between both sections. Therefore, ink is consumed with almost no waste. Because of the existence of this small space, the suction force is extended thoroughly, and ink does not remain at certain areas. Also, there is a space around the fill/drain port 3, where the suction force affects, the last portion of ink is collected to that space, and sucked out.

Filed: 1996-08-21
Abstract: PROBLEM TO BE SOLVED: To shorten the time for teaching by automatically moving a nozzle in the normal direction of a work and to improve cutting work quality regardlessly of the set position of the work. SOLUTION: A machining head is moved by an NC controller 51, a coordinate measuring means 41 finds the X, Y and Z coordinates of three points near the machining position based on a signal from a measuring element 59 provided at the machining head, and an arithmetic processing part 71 finds the rotating angle for deciding the attitude of the nozzle by finding a normal vector to the surface of the work based on the coordinates of these three points.

Title: Seat position maintaining type suspension seat
Inventor: NUMAMOTO YUKIMASA
IPC: B60N2/90
Filed: 1984-10-19
Abstract: PURPOSE:To facilitate a driver's getting in or getting out of a car by engaging seat position maintaining means with each other at a suspended state by using a signal from the sensor, which detects whether the ignition switch is in an energized state or in a suspended state, thereby fixing the seat position so as to maintain the height of the seat when the driver gets off the car. CONSTITUTION:When a seat is under automatic control, it is always confirmed that an ignition switch is in an energized state. When the switch is in a suspended state, a signal is sent to a controller from a relay sensor connected to the ignition switch, and a claw of a hinge 40, which is pivottaly supported via a pin on the base 23, is engaged with a recessed part of a striker 38 which is installed at the bottom surface 27 of the seat. Thus, the vertical position of the seat 18 is held at the predetermined position. As a result, even when the driver is off the seat 18, since neither the air pressure in a cylinder 42 nor the force of the spring 20 pushes up the seat 18, the height of the seat 18 is held unchanged, thereby facilitating the driver's getting in or getting out of the car.
