Title: Heat source device
Inventor: KUBOYAMA NOBUYOSHI
IPC: F24J3/00
Filed: 1981-03-31
Abstract: PURPOSE: To make the rise and distribution of temperature uniform by a method wherein the frictional heat of air is accumulated by a heat accumulating material within a hollow heating chamber of small capacity to thereby provide a heat source of a capacity equal to several tens to several hundreds times the capacity of the hollow heating chamber.  
     CONSTITUTION: When a rotary vane 6 is rotated by energizing a motor 5, a decompressing and frictional heat generating mechanism X operates and the air within the hollow heating chamber 1 is gradually discharged and decompressed. Accordingly, the difference between the pressures in the inside and the outside of the hollow heating chamber increases gradually but when it reaches a certain value, both of the pressures are brought under a substantially balanced condition. In this case, the phenomenon of stagnation of the air in a frictional heat genereating section A within the area of rotation of the rotary vane 6 takes place and the friction between the air and the rotary vane 6 is kept repeated so that the temperature in the hollow heating chamber 1 increases and heat energy is accumulated gradually by the heat accumulating material 3. Thus, when the temperature in the chamber 1 reaches a desired value, the chamber 1 can be utilized as a heat source for the decompressed air.

Title: Optical device for photographing stereoscopic video
Inventor: NAKAGAWA MASASHI
IPC: G03B35/08
Filed: 1995-03-07
Abstract: PURPOSE: To obtain a compact and lightweight streoscopic video photographing device with a variable convergence angle by moving the center position of a video pickup screen on an image face to change an angle formed by optical axes and to adjust a convergence angle. CONSTITUTION: Respective image faces are formed by right and left videos through lens systems 1a, 1b and horizontally movable image pickup elements 2a, 2b are moved in the horizontal direction on the image faces to adjust a convergence angle θ1 formed by respective optical axes (a), (b). When a subject exists near the elements 2a, 2b, the elements 2a, 2b are moved in the distant direction, and when the subject exists on a distant position, the elements 2a, 2b are moved in the approaching direction. Since the convergence angle θ1 can be changed in accordance with the distance of the subject by such a constitution without moving the lens systems 1a, 1b, the convergence angle θ1 can be changed without providing this device with a large and heavy movable part. A motor can be used as a moving means for the elements 2a, 2b.

IPC: B21F45/24
Filed: 1978-04-21
Abstract: PURPOSE: To contrive the improvement of the production efficiency and the saving of the material  cost, by giving a tension to the multiple groups of large diameter wires being sent parallelly so as  to reduce the diameter of the wire and to eliminate the interwire gaps, and by applying adhesives  to this wire group for every specified interval on purpose to bond together, and then, by cutting  the wire group into a specified length.   
     CONSTITUTION: The large diameter wires 20, uncoiled from all wire reels 3 of the obliquely  arranged plural sets of reel stands 1, are parallelly lined up and are sent out as the wire group W.  From the first roll to the final roll 21W24 in this order, the roll's circumferential speed is sequentially increased so as to give a tension to the wire 20 whose diameter is hereby reduced. Hereupon, the high frequency heating coil 25 prevents the work hardening of the wire group W while  the plastic deformation; hereby, the deformation resistance is reduced, which prevents the breaking of the wire 20 while the wire drawing work. Thus prepared wire group W with a specified  diameter is passed through the gapless shape adjusting comb 7 and the hourglass type roll 8 so as  to remove the gap between wires 20; this gapless wire group W' is applied with adhesives applying roll 13 for every specified interval, and is hardened in the drying furnace 14; after that, the  wire group W' is cut by the cutting roll 16 into a specified length and the rows of pin group P is  obtained.

Abstract: PROBLEM TO BE SOLVED: To provide a simplified and stabilized production process for a large sized bulk body of high orientation by decomposing and melting raw materials for the bulk body at a temperature higher than the decomposition and melting point of an oxide to be prepared, then reducing the temperature lower than the decomposition and melting point and sowing a seed crystal to the melt. SOLUTION: The bulk body of RE123 oxide superconductor that is represented by a general formula: REBa2Cu3Ox (RE is one or two or more kinds of rare earth elements) and has a 123 phase crystal structure is prepared by melting and coagulating method. In this preparation, raw materials (or their precursors) for the bulk body are held at a temperature higher than the decomposition and melting point of the 123 phase of REBa2Cu3Ox oxide to be prepared. Then, the molten product is cooled down below the crystallization temperature. By utilizing the time until the crystallization is initiated, seed crystals are brought into contact with the treated raw materials and they are kept at the crystal growth temperature or they are slowly cooled down along a temperature gradient, thereby obtaining the objective bulk body of RE123 oxide superconductor mainly comprising the RE123 phase from the seed crystals.

Filed: 1981-03-31
Abstract: PURPOSE:To obtain a semiconductor memory which can write at high speed and with low power consumption, by clamping bit lines of the memory cell consisting of PNP load transistors and transistors forming a flip-flop at a prescribed electric potential. CONSTITUTION:An electric currnt which is drawn into an electric curent source IW1 in accordance with write controlling signals VW1, VW2 from a read and write controlling means WA, flows through a bit line B1, etc., after passing through a transistor TB1, and, moreover, the electric potential of the line B1 is clamped at a sufficiently low electric potential by the base potential of a transistor TD1 for clamping. Therefore, a large write current flows to a transistor corresponding to the line B1 consisting of an FF of a semiconductor memory cell Cell, and high speed writing is performed. In the same way, at the time of reading, the charge accumulating effect is made smaller by supplying a samll electric current from a transistor for an FF at the ON side, and the writing speed is further increased. Therefore, a semiconductor memory consisting of PNP load transistors of low power consumption and FFs and which can make high speed writings, is thus realized.

Abstract: PURPOSE:To obtain a cap wherein manual opening at an early stage may be small and workability is excellent by setting positions for first, second and third hinges so that travel of a tip of a lid is at a specific value or lower when a lid is rotated from a fully closed position to a state where rotation centers of the respective hinges are on a plane. CONSTITUTION:When a rotation center of a first hinge 31, a rotation center of a second hinge 32 and a rotation center of a third hinge 33 are on a plane C, deformation of a band plate 40 is the maximum and this is the change point. If a lid 20 falls toward an opening side from this change point, spring force of the band plate 40 functions to the lid 20 in an opening direction, while if the lid 20 falls toward a closing side from this point, spring force of the band plate functions to the lid 20 in a closing direction. Positions of the respective hinges are set so that the change point is reached when a tip of the lid 20 rises by 10mm after the lid is opened from the closing state. In addition, an angle theta made by a line C and a cap 10 of a top plate 13 is approximately 70 deg..
