IPC: F03B13/26
Filed: 1985-05-13
Abstract: PURPOSE:To enable a water wheel generator placed in a river where a water head is small to generate a great capacity of electricity by connecting a main shaft of a water wheel with the generator by way of a speed increasing gear, and also by arranging the plural number of generators in parallel. CONSTITUTION:The plural number of water wheels G which is arranged in parallel to the direction of the width of a river, is provided on a concrete base 5 placed on a river bed 10 where the concrete base 4 for the generator 2 is projected out of a water level 11.

Title: Manufacture of polyester tubular film having excellent thickness uniformity
Inventor: WATANABE YUTAKA
IPC: B29C55/26
Filed: 1983-06-06
Abstract: PURPOSE:To form stably a tubular film having uniform thickness by a method in which a film being expanded after draw-starting point under a specific condition is directed to a draw-regulating ring and then redrawn in such a range that the lenth of all drawing zone is several times greater than the final expansion radius and the final draw ratio is a specific one. CONSTITUTION:If the vertical length of all drawing zone from draw starting point (a) to draw ending point (b) is l for the advancing direction of a film, vertical distance l1 is set at the position (c) meeting the formula. The two-stage drawing of the film is made until the final draw ratio in both vertical and crosswise directions becomes 2.5- 6 times under a condition meeting the inside diameter gamma1 of a draw-regulating ring and the formula and within a section where the vertical length of all drawing zone from the draw starting point to draw ending point is within the range of 0.5-5 times the final expansion radius. Since drawing speed in the early period of the starting of drawing can be greatly delayed, extreme increase of the yield-point strength at the starting time of drawing can be suppressed and also the orientation and crystallization in the early period of the drawing can be avoided. By the synergism of excellent both effects, the neck portion at the starting time of drawing can be very smoothly and uniformly drawn in stable shape.

IPC: B29B7/76
Filed: 1983-06-07
Abstract: PURPOSE:To permit the sending of mixed resins in a static flow as well as optimal stirring of the mixed resins according to the discharge amount of mixed resin components by a method in which the first and second mixers are set in such a way as to partly cross the mixers mutually, and the charging of each resin component into the mixing chamber or stoppage of the charge is controlled by a switching rod. CONSTITUTION:In mixing (or discharging), a switching rod 30 goes forwards, and resin components mixed in the mixing notch 31 of the switching rod in the first mixing chamber 10 is flowed through a communication path 39 formed by the same mixing notch 31 into the second mixing chamber 20, where the resins are flowed to the right-angle direction with secondary stirring. The resins well stirred is discharged in a static flow due to the damping of the flow rate of the mixed resins from an outlet 21 into molds. The opening area of the communication path 39 can be optionally altered by regulating the entrance to the first mixing chamber 10 of a stopper pin 38 according to the discharge amount of mixed resin components, thereby permitting optimal mixing stirring and optimal flow rate of resins to obtain. In stopping the mixing (or circulation), the swtiching rod 30 is retracted.

Filed: 1989-04-22
Abstract: PURPOSE:To reduce the manufacturing manday and cost of a steering wheel core iron by forming a spoke part core iron and a boss plate into a coutinuous integrated body. CONSTITUTION:A core iron is formed by welding a connecting plate 12 to a boss 11 and a ring part core iron 14. As a spoke part core iron and a boss plate formerly separated are formed of a continuously integrated connecting plate 12 this time, three parts are welded in total (formerly five parts), that is, between the connecting plate 12 and the boss 11, and the connecting plate 12 and the ring part core iron, thereby reducing the manufacturing manday and cost of the steering wheel core iron C1, as well as achieving the lightweight and compaction of a steering wheel W1. Furthermore, because of forming the spoke core iron 23 and the boss plate part 22 into an integrated connecting plate 12, the characteristic frequency of the steering wheel W1 becomes higher, thereby preventing resonance at the time of idling.

Abstract: PROBLEM TO BE SOLVED: To reduce a housing space by rotatably connecting a lengthwise directional intermediate part and both end parts of a large number of continuously connecting sash bars, and layering/folding up a door in the thickness direction by expansibly forming an expansible link in a pantograph shape. SOLUTION: First connecting holes are formed in a lengthwise directional central part of continuously connecting sash bars 3, and second/third connecting holes are formed in upper/lower tip parts. The first connecting holes of the two continuously connecting sash bars 3 are put together to be rotatably connected by rivets 8a. Respective sets of continuously connecting sash bars 3 connected by the rivets 8a are rotatably connected by adjacent sets of rivets 8b, 8c to constitute an expansible link 9. The expansible link 9 can be expanded in a pantograph shape up to a folded-up state so as to be layered from a maximally extended state. Two sets of expansible links 9 are connected between both end part frame members and an intermediate frame member to constitute an expansible door.  Thus, the door is opened/closed by expanding the expansible link 9 so that a space is sufficiently reduced by folding up the door.
