Title: Cooling water supply system for stator winding of rotary electric machine
Inventor: MATSUBAYASHI HIROSHI
IPC: H02K9/19
Filed: 1979-06-04
Abstract: PURPOSE:To effectively cool stator coil cooling water with a high flow velocity by increasing in cooling capacity a heat-exchanger in the vicinity of the warm drain inlet of a storage tank, the heat-exchanger being made larger than the other portions in heat-exchange capacity. CONSTITUTION:A number of heat pipes 3b made by enclosing the condensation liquid with large evaporation latent heat in sealed pipes are used as heat-exchangers. A storage tank 1 is partitioned with a partition plate 17 in two of which stator coil cooling water 8 is stored in one and heat-exchanger cooling water 16 is fed to the other. The pipes 3b are arranged so that the evaporating and condensing portions thereof may contact with cooling water 8 and cooling water 16 respectively and the density thereof may become large in the vicinity of an inlet for the hot drain with a high storage temperature. Thereby, the stator coil cooling water with a comparatively high flow velocity can be cooled efficiently.

Title: Production of fixing grooves for multicore connection of optical fibers
Inventor: NAGASAWA SHINJI
IPC: G02B6/24
Filed: 1978-06-09
Abstract: PURPOSE:To obtain the production process of high accuracy and high volume productivity and economy by the simple method of arraying a plurality of glass bars having the same section so as to contact at the longer side, and heating and stretching these. CONSTITUTION:Glass bars 6 having the same rectangular section are arrayed so as to contact at the longer side. At this time, these are arrayed with a deviation by the length of the shorter side. Next, the glass bars 6 are heated up to the melting point, after which they are stretched by being applied with even tension in the axial direction, whereby the section of the glass bars 6 is reduced. Next, the glass bars 6' with  the reduced section are cut out to a suitable length. In this stretching process, the  grooves 7 also reduce at the same ratio owing to the reduction of the glass bars 6.  This reduction may be achieved evenly at an arbitrary reduction rate and its dimensional accuracy may by reduced as well by controlling of the tension and the rate of  stretching. In this way, the production process of high accuracy and high volume  productivity and economy may be obtained.

Filed: 1988-03-22
Abstract: PURPOSE:To obtain a normal output signal even when about half of a photodetecting face is shielded by a method wherein one of sets of filters and photodiodes for three colors of red, green and blue is formed in a cross and the other two sets are separately arranged around it. CONSTITUTION:A red filter 20 and a photodiode 50 for red are formed individually to be cross-shaped. Green filters 30, photodiodes 60 for green, blue filters 40 and photodiodes 70 for blue are arranged alternately around the diode 50 in such a way that they are symmetric with respect to a point while the center of the diode is set as the center of symmetry. By this constitution, even when, as an example, an outer frame of a photodetecting part shades a right half of an IC chip 10, the ratio of photodetecting quantities of the diodes 50, 60 and 70 is the same as when the chip 10 is not covered at all. Accordingly, individual electric signals by the diodes 50, 60, 70 of three colors are equally reduced by half; normal signals as output signals for white balance setting use of R/G and B/G can be obtained.

Abstract: PURPOSE:To obtain a crucible having a long life without generating any crack in the grain boundaries thereof by a method wherein the crucible, having a predetermined configuration in which one end thereof is sealed, is constituted of the single crystal of molybdenum substantially. CONSTITUTION:Forging work is applied on a column type slug 1, having a height H1, so that a height reducing ratio (=H1-H2/H1X100) becomes 60% or more whereby a first intermediate workpiece 3 is obtained. The surface layer 4 of the first intermediate workpiece 3, shown by diagonal lines in a diagram, is dead zones, in which the deformation of a material is hindered by a friction force, while the side parts 5 of the same are the parts of a low working ratio, which are deformed so as to be pushed outwardly, and, therefore, both of them are hardly changed into single crystals by heat treatment. Accordingly, respective surfaces of the surface layers 4 and the side surface parts 5 are ground by 5% or more with respect to the diameter of the crucible to manufacture a second intermediate workpiece 6. Next, boring work is applied to obtain a hollow and bored finishing product 7 having an inner side surface 8 and an inner bottom surface 9. Heat treatment is applied on the product 7 at the temperature of 1800 deg.C or higher to change the crystal into single crystal whereby a finished product may be obtained.

IPC: G09G3/36
Filed: 1996-03-26
Abstract: PURPOSE: To improve the resolution of a liquid crystal display device in a vertical direction and to obtain satisfactory display quality for a large screen. CONSTITUTION: The signal lines of the liquid crystal display device are arranged so as to constitute a matrix with scan lines and a picture element 109 is selected by a scan line and a signal line. In an odd field, the scan line corresponding to the odd field and the scan line corresponding to the even field adjacent to the scan line corresponding to the odd field are made into a pair to select scan lines. The selected tow scan lines are applied with the same odd field video signal. In an even field, two scan lines are selected by shifting every one scan line, then a pair of scan lines is selected and applied with the same even field video signals. Moreover, the polarity of the video signals supplied to the signal lines is reversed for every field.  Thus, a fine vertical resolution is obtained with a simple construction, and a high picture quality liquid crystal display device is realized without causing frickers.

Title: Double-wall contacting type heat exchanger and preparation thereof
Inventor: KODAMA TATSUAKI
IPC: F28F1/04
Filed: 1979-06-04
Abstract: PURPOSE: To prevent the mixing of liquids even when a hole is made in a wall by a method wherein two metal pipes are wound in plural times spirally, touching each other and being lined in parallel and are formed into a disc having two passages for liquid.  
     CONSTITUTION: Two oval metallic pipes 4 and 5, being lined in parallel so that the wall surfaces thereof touch each other, are wound spirally in plural times and formed into a disc. The pipes thus formed are given an outer force shown by an arrow F so that the oval sections thereof are transformed into the shape of square, thereby the area for heat transmission being enlarged. By forming the pipes in this way, the liquids flowing through two passages C and D do not mix with each other even when corrosion or the like makes a hole in one wall, which makes safe even the heat exchange of the noxious liquid is performed. In addition, since both left and right sides of pipes become heat-transmitting surfaces, the area for heat transmission is enlarged and also the device can be made compact.

Title: Tape driver
Inventor: MIZUGUCHI NOBUAKI
IPC: B65H23/18
Filed: 1983-04-20
Abstract: PURPOSE:To attain a fixed tape driving speed by having the 1st control which detects the number of revolution of both take-up and supply reels and obtains a convex parabola for the time change of the tape driving speed and the 2nd control which compensates the part where the tape driving speed is low obtained from the 1st control. CONSTITUTION:It is supposed that a reel motor 2 has a sufficient torque to the variance of load. The control (a) is given to the tape driving speed through a feedback loop (the 1st control) of only a detector 6. Then the 2nd control is added by an operator 7 to reduce the variation. The operator 7 checks the number of revolution of both take-up and supply reels 3 and 4 and delivers a signal adversely proportional to the number of revolution of either reel which is less than a certain level. Then the control is applied to compensate the areas of oblique lines in the figure, and the tape driving speed (b) is obtained. Thus the tape driving speed can be approximately kept at a fixed level with these two controls.
