Title: Plastic working method to manufacture seamless hollow body with bottom or seamless pipe
Inventor: NICKEL WILHELM
IPC: B21K21/14
Filed: 1999-11-05
Abstract: PROBLEM TO BE SOLVED: To obtain a hollow body or pipe with specified outside diameter and wall thickness while reducing reheating time and preventing the danger of the bottom being broken through by using a mandrel with a spherical end when the hollow material pipe, wherein the bottom material integrally formed at the time of boring the hollow material pipe is reduced in thickness from the edge area toward the center, is punched. SOLUTION: A steel ingot or a continuous-cast steel is heated to the plastic working temperature, and with dies and a punching mandrel 2, rolling into a hollow material pipe is done so that the bottom is shaped into a truncated cone. With the dies, the material of a bottom portion 6' is reduced in thickness from the edge area toward the center and the bus line contour of the bottom portion 6' is brought into agreement with a hyperbolic binding string through the first approximation. Then the hollow material pipe is punched into the final size with a mandrel 17 on which a spherical end area 18 formed and one or more ring dies 7, and when necessary, the material is reheated between passes so that the bottom 6" is remained on the hollow material pipe or cut from the hollow material pipe.  Thus, the seamless hollow body with a bottom or a seamless pipe of 200-1,450 mm outside diameter and 20-250 mm wall thickness can be obtained.

Title: Positioning device
Inventor: KINO HIROYUKI
IPC: G05B19/35
Filed: 1995-11-08
Abstract: PROBLEM TO BE SOLVED: To provide a device which is not adversely affected by external noise without the deterioration of stop precision and the occurrence of hunting. SOLUTION: A stop range setting circuit 1 sets a stop range being a control object based on a target position signal (a) and PBR 6 detects the present position of the control object driven by a motor 5. A comparison circuit 2 compares the present position of the control object with the setting stop range. While the control object does not reach in the stop range, a signal beyond range (e) and a rotary direction indication signal (f) are outputted. The signal being stop range is inputted to a driving start judgment circuit 3. When the signal being stop range continues for more than prescribed time, a driving permission signal (g) is outputted to a driving circuit 4. The driving circuit drives the motor in a direction that the driving direction indication signal shows.  Thus, an instantaneous ON/OFF signal is not inputted to the driving circuit owing to external noise even if it comes in.

Title: Four-way valve for refrigeration cycle
Inventor: ARAKI TOKINORI
IPC: F16K11/065
Filed: 1987-12-14
Abstract: PURPOSE: To prevent liquid compression by an arrangement wherein the superconductor element in a sliding valve exhibits diamagnetism when the temperature of refrigerant drops below a specified level on the low pressure side to float the sliding valve relative to a valve seat made of a magnet thus bypassing refrigerant on the high pressure side to the low pressure side and ensuring superheat. CONSTITUTION: A slide valve 25 slides on a valve seat 30 on the inner surface of a valve body, i.e., a cylinder 17, to switch the refrigerant path. A superconductor element 32 is bonded to the surface at the sliding valve facing the valve seat while being exposed to the refrigerant on the low pressure side and a magnet is employed partially or entirely for the valve seat 30. When the temperature of refrigerant on the low pressure side drops below a specified level due to deficiency of evaporation capacity of an outdoor heat exchanger at the time of low outer air temperature in heating cycle, temperature of the element 32 drops to exhibit diamagnetism at a critical temperature.  The sliding valve is floated by magnetic force of the valve seat to bypass refrigerant on the high pressure side to the low pressure side and increase enthalpy of sucked refrigerant to ensure superheat thus preventing liquid compression of a compressor 101.

Abstract: PURPOSE:To conduct the evaluation test for the infrared ray image pickup device with nearly the same contents as those of a field test at less expensive than the execution field test by providing a CCD memory device, a CCD memory drive circuit and a collimator in the projector. CONSTITUTION:A D/A converter 11 converts a digital television signal 103 from a scanning converter 10 into an analog signal again. Since the analog signal is synchronous with the operation of a CCD memory 12, the memory 12 receives a signal 105 from a CCD memory drive circuit 13 to receive an analog television signal 104. The signal 104 gives a temperature difference to a Peltier element connecting to the CCD memory element corresponding to the picture element depending on luminance information of each picture element of the signal 104. Since CCD memory elements and Peltier elements corresponding to them are arranged in a 2-dimension matrix, the memory 12 is processed as an infrared ray source of the collimator 14, then an infrared ray picture depending on a focal distance of the collimator 14 is projected.
