Title: Vertical-shaft type windmill
Inventor: TOMIZAWA MASAO
IPC: F03D3/06
Filed: 1980-04-23
Abstract: PURPOSE: To prevent occurrence of fatigue damage due to the fluttering of a blade by giving constantly a tensile force in the direction of a wing chord to a cell wing and thereby preventing the slack on the surface of the blade.  
     CONSTITUTION: After the flexible blade surface is stretched, spring boards 44 are inserted from the insertion openings 43 of a sack-shaped parts 42. Since the length of the spring board 44 is somewhat larger than that of the sack-shaped part 42, the flexible blade surface is given the tensile force in the direction of the wing chord, whereby the cross section of the cell wing 7 is shaped into a complete form of a wing. Since the cell wing 7 is given the tensile force constantly by the spring boards 44 even when the force of air acts on the wing at the time of rotation, the fluttering of the blade surface due to the fluctuation of the force of air is not caused and thus no fatigue damage is caused on the surface of the blade.

Title: Thermal head and manufacture thereof
Inventor: SAIDA KATSUAKI
IPC: B41J2/345
Filed: 1984-03-23
Abstract: PURPOSE:To alleviate local concentration of current density upon driving a heating element by electric power and contrive a longer useful life of the heating element, by a construction wherein the resistor having a bent part and constituting a heating element is provided with an appropriate nonuniform sheet resistance distribution. CONSTITUTION:In a thermal head comprising a resistor having a bent part, the sheet resistance of the bent part of the resistor is set to be increased from the inside toward the outside of the bend. As a result, the sheet resistance of the resistor 1 is highest on the inside 3 of the bent part and is lowest on the outside 4 of the bent part. By providing the heating element with such an appropriate sheet resistance distribution, it is possible to set a resistance ratio R23/R22 to 1. Accordingly, the current density in the bent part of the resistor is restrained from being concentrated on the inside of the bent part, and the current density in the resistor can be uniformly distributed.

IPC: H04M3/56
Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To enhance the visual confirmation performance in the video conference system by editing a video image again sent from opposite party and displaying on a screen through magnification. SOLUTION: A communication controller 1 receives a video image picked up by a TV camera of an opposite party from a communication controller of the opposite party.

Title: Absorber
Inventor: FURUKAWA MASAHIRO
IPC: F25B37/00
Filed: 1990-03-06
Abstract: PURPOSE:To improve the heat transfer performance of a heat transfer tube by forming a plurality of projected lines having a twisted angle with a tube axis on the outer surface of the tube and installing the heat transfer tube which defines a curved surface for the top and bottom of the lines to a middle stage of an absorber heat exchanger. CONSTITUTION:When an absorption solution sprayed over an absorption heat exchanger 5A from an absorption solution spray device 4 flows down from a heat transfer tube 5 in an upper stage to a heat transfer tube 5 in a lower stage, Marangoni convection is generated on the absorption solution by projected lines 12 formed on the outer surface of the tubes, thereby improving the heat transfer performance of each heat transfer tube. When a heat transfer tube 5 in the lower stage is slightly curved for example, the absorption solution which drops from each heat transfer tube in the lower stage becomes unequal. When the absorption solution drops unequally on a heat transfer tube 6 provided with projected lines having a twisted angle in the middle stage, the absorption solution in guided by the heat transfer tube 6's plurality of projected lines 12 having the twisted angle so that the solution may flow to a part where only a small amount of solution drops. As a result, the absorption solution drops virtually equally to the heat transfer tubes 5 in the lower stages. The absorption solution flows substantially equally on the outer surface of each heat transfer tube 5 in the lower stages, thereby improving the heat transfer performance.

Abstract: PROBLEM TO BE SOLVED: To hold a paper sheaf stacked on a bin, by a pair of rollers to take it out without hindrance by providing a push-back lever for separating the paper sheaf on the bin from a stopper interlockingly with the movement of a lower arm for holding a lower roller brought into contact with the lower face of the paper sheaf from below the bin so as to lift the paper sheaf. SOLUTION: A takeout unit 40 takes out a paper sheaf while holding it from a bin 31 set to a level X2 . This takeout unit 40 has a lever 41 for pushing back the end part of the paper sheaf from a stopper 34 of the bin 31, a lower roller 43 for lifting the paper sheaf from below, and an upper roller 42 coming in pressure contact with the paper sheaf from above. When a lower arm 46 is rotated in the direction of an arrow mark (c) at the time of taking out, a cam face 46a formed at the lower arm 46 presses the lever 41. The push-back lever 41 is therefore rotated in the direction of an arrow mark (e) around a supporting shaft 97 as a fulcrum so as to retreat the paper sheaf on the bin 31. Cutouts that can make the push-back lever 41, lower roller 43 and lower arm 46 enter are formed at the lower end part of each bin 31 and the stopper 34.

Filed: 1981-04-16
Abstract: PURPOSE:To obtain a reliable and small-sized device, by setting the running direction of a tape in one predetermined direction in tape ejection, by a switching means of changing running directions of the tape. CONSTITUTION:A part of a change plate 48 is bent up as a restriction piece 48', which is aligned to the projecting piece 18 of an engaging arm 16 with a cartridge unloaded. Consequently, even when the running direction of a magnetic tape is reversed, unloading a tape cartridge temporarily makes the projecting piece 18 of the engaging arm strike the restriction plate 48' without fail to push it back to the original position.Therefore, when the tape cartridge is unloaded temporarily and then loaded again for initial operation, a capstan shaft 40 and a pinch roller 24 press against each other without fail, so the magnetic tape runs first in one predetermined direction.
