Inventor: MORI MASATOSHI
IPC: B21D28/34
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To provide a punching press not leaving any curved strain by press working in a work. SOLUTION: In the punching press 10 providing with the die 11 arranged in the upper side of the press, the punch 13 fixed and arranged in the lower side and the plate 15 provided in the punch side, the surface 15b facing the die of the plate 15 is formed into an upward projecting curved surface and an elastic body 17 is provided in the die 11.

Inventor: JIYON II FUUTSU
IPC: G01N21/78
Filed: 1995-03-28
Abstract: PURPOSE: To provide a method for monitoring and in-system concentration control of an aqueous polyelectrolyte with a fluorochromatic dye, and more specifically, for monitoring and/or control of reduction in concentration and/or dosage of the polyelectrolyte by which a substantially linear response to the polyelectrolyte concentration can be obtained irrespectively of experimental skill of a worker.

Title: Roll-over transfering device
Inventor: TANI HIROYUKI
IPC: B65G47/90
Filed: 1990-03-22
Abstract: PURPOSE:To stabilize stacking attitude in a roll-over transfering device for a shadow mask for a color CRT by inching the roll-over device and a conveyor as much as they are relatively offset so that products can be shifted and stacked on the conveyor. CONSTITUTION:A mask 21 which is taken out of a molding device is put on a mask supporting member 22 in a roll-over device 10. The mask 21 is retained by the grip 23a of an air cylinder 23 and the roll-over device 10 is moved to the side of a belt conveyor 30 by an air cylinder 14. The mask 21 is rolled over by an air cylinder 19 and placed on the conveyor 30, when the grip 23a is relieved from retention. In case of repeated operation for stacking, a sensor 32 detects the mask to inch the conveyor 30 until a sensor 31 is turned off. In this way, stacking is performed in a stable condition.

Title: Heterogenous membrane and preparation thereof
Inventor: ANAZAWA TAKANORI
IPC: B32B5/18
Filed: 1983-04-22
Abstract: PURPOSE:To form a heterogenous membrane having voids reduced in air permeation resistance provided therein, by stretching a thermoplastic polymer having crystallizable property as a membrane material by treating the same in combination of melt-molding, heat treatment and stretching. CONSTITUTION:The greatest characteristic on a manufacturing process resides in the cooling condition of a spun yarn. The range of 1-30cm below nozzle orifice is cooled only by a weak air stream and, when a polymer slow in a crystallizing speed such as polyester is used, the hollow yarn or film issued from a spinning orifice is pref. prevented from the lowering in temp. in order to prevent the cooling thereof. By the cooling in the vicinity of the spinning orifice due to the weak air stream, temp. distribution is formed between the surface and the interior of the membrane and, by stretching the hollow yarn or film in a high draft ratio, only the membrane surface is highly oriented to be brought to an oriented crystal and a structure having a laminated lamellar crystal developed in the membrane interior is formed.

Title: Rubbing sound evaluating method
Inventor: KAWAI MASAO
IPC: G01M99/00
Filed: 1979-06-06
Abstract: PURPOSE: To secure the evaluation for the intensity of the rubbing sound in case the rubbing occurs at a large-scale rotary machine, by mixing the rubbing mimic signal into the sound detecting system for the histogram process and then giving the control to the scale of the mimic signal so that the two peaks obtained may be nearly identical to each other.  
     CONSTITUTION: Rotary reference signal (a) generates trigger pulse (b) which is delayed by time T 0  and via switch 101 and timing control circuit 102 each. Then rubbing mimic signal (c) having an optional known intensity is generated via signal (b) from AE sensor 104 and through pulser 103. Both signal (c) and the aural signal sent from the rotary machine are detected and mixed each other by detection sensor 33, and this output undergoes the histogram process at histogram process part 11 and via amplifiers 4 and 5, envelope curve circuit 7, band pass filters 6 and 8 plus comparator 9 each. The control is given to signal (c) so that the two output peaks of the signal may be the intensity nearly identical to each other for the comparison. Thus the intensity can be evaluated for the rubbing sound.

Abstract: PURPOSE:To provide an ink dot printer, by a method wherein a number of small heaters are arranged and immersed in an ink liquid, each heater is made conductive selectively and a bubble is produced above the heater, and when the bubble  is broken only one liquid drop is sprung vertically. CONSTITUTION:A number of small heaters 1 are arranged regularly in lattice structure within a printing member 2, an ink liquid 3 is entered to such depth that the heater 1 is slightly hidden by water level (preferably to depth nearly equal to diameter of a bubble produced) and the water level is always held constant. A recording paper 14 is passed at a prescribed distance from the water level, the heater 1 is made conductive selectively, and printing is carried out by jumping of the ink drop. If surface tension of the liquid and diameter of the bubble satisfy a certain condition, one comparatively small bubble (for example, 0.3-2mm.phi) is floated from liquid. When the bubble is broken at the liquid surface, one liquid drop having size corresponding to diameter of the bubble (about 1/10 of diameter of the bubble) is sprung from the liquid surface vertically.
