Title: Cooling method for metallic pipe
Inventor: HANNOKI MICHIHARU
IPC: C21D9/08
Filed: 1985-03-11
Abstract: PURPOSE:To cool a metallic pipe material having large hardenability quickly and efficiently without generating quench cracks in the stage of cooling said pipe material by cooling first the metallic pipe with mists then cooling the pipe with gaseous jets. CONSTITUTION:The pipe material A of a high temp. produced by the metal such as high C-Cr-Mo steel having the large hardenability is cooled while the material is conveyed by rollers 18. The pipe material is first conveyed to a mist cooler 11 where the material is cooled by the liquid drop-like small mists sprayed from mist nozzles 14 by air headers 12 and water headers 13 toward the periphery of the pipe A down to about 350 deg.C. The pipe is then fed into a gaseous jet cooler 15, where the pipe is cooled by the gaseous jets blown from slit nozzles 16 connected to air headers 17. The metallic pipe having the large hardenability is thus cooled by such two-stage cooling without generating quench cracks.

Title: Device for frugal use of developer
Inventor: TEIMOSHII JIEI SURENSUKII
IPC: G03G15/08
Filed: 1990-02-28
Abstract: PURPOSE: To provide a developer doling device preventing the blistering of an auger free end and the bridge formation of toner by providing the device with a means controlling the movement of an upper side by mutually actuating with the free end of a spring and also giving a bridge formation prevention function to a toner carrying mechanism. CONSTITUTION: A coil spring auger 40 is rotated in a direction where developer is doled out by a motor 50 through a worm gear device 52, and moves the developer to a doling out aperture 34. The coils 40a, 40B and 40C of an auger end part abut on the chamfered surface 56 of a shoe 54, so that they are restrained by the shoe 54 though the auger is rotated and the end part of the auger starts winding only by one rotation in several. When the coil is wound, energy is stored. At a certain point, the coil slips overcoming a resistance for a rotation and is returned to a normal rotational position, so that the energy stored is released. The release of the energy is transmitted to the developer at the periphery of the auger 40, and strong hitting actuation is actually added, so that bridge formation prevention actuation is performed.

Abstract: PURPOSE:To identify the bidder who remains lastly by a simple method by reading registration numbers of bidders by a magnetic card reader incorporated in a remote switch, and modulating an oscillation frequency with the read registration numbers. CONSTITUTION:A bidder inserts a magnetic card in which a registration number is entered into the reader 4 of the remote switch, and the read registration number is converted by a code signal generator 5 into a coded serial signal to turn on and off a modulating wave generated by a modulating wave oscillator 3. A radio wave from the remote switch is demodulated by the demodulator 11 (A and B) of the identifying device and inputted to a low-pass filter 12 (A and B) corresponding to the modulation frequency, and made into a coded signal by the remote switch. This signal is passed through a low-pass filter 13 (A and B) corresponding to the frequency of the coded signal to obtain a DC signal, which is inputted to a microcomputer 17 through a comparator 14. When the signals decreases in number to one, the signal from an OR circuit 15 is read in the microcomputer 17 through a digital input unit 16 to identify the registration number of the bidder who remains lastly.

Abstract: PURPOSE:To obtain a titled working device that has perfect sealing to prevent leakage of liquid at all times and to form the device by one process in making hydraulic bulge working of a straight tube to make sectional forms in longitudinal direction different by increasing pressure applied to inner periphery of oil seal folowing rise of bulge pressure. CONSTITUTION:After mounting a straight tube 1 to above-mentioned device, guide dies 5, 6 are set and clamped. Next expanding heads 3, 4 are thrusstd in the inner periphery of both ends of the tube 1 to expand the tube ends to trumpet shape. Oil pressure is applied to inside of oil seal 9 from an oil hole 11 by a low pressure pump to bring the seal 9 into close contact with the inner periphery of the tube 1. A high pressure pump 18 is operated next, and pressure oil 12 is supplied into the tube 1 to apply pressure. At this time, a valve 20 is opened to exhaust 13 air in the tube 1. Then, valve 20 is closed to make the pressure bulge pressure P1.

IPC: B23Q15/00
Filed: 1989-02-28
Abstract: PURPOSE:To align one main spindle position to the other main spindle position by forward rotation by detecting by the first and second position detectors a present position calculated in its deviation and calculating a common target position of a master spindle and a slave spindle. CONSTITUTION:The first and second position detectors 55, 56 detect a present position, when its deviation is within a predetermined value, a larger position in a direction of forward rotation of the present positions is calculated as a common target position of a master spindle 13 and a slave spindle 19. When the deviation exceeds the predetermined value, for the larger present position in a direction of forward rotation, adding a multiple integer of the maximum detection value of the detectors 55 or 56 to the smaller present position to calculate a position with a deviation absolute value less than a predetermined value as an offset position, the larger position in the direction of forward rotation is calculated as the common target position of the master spindle 13 and the slave spindle 19. At the time of operation preparation, the present position or the offset position of the master spindle or the slave spindle is moved to the calculated target position, and synchronous position alignment can be performed in the direction of forward rotation.
