Title: Flying toy
Inventor: RI KOKUKIYOU
IPC: A63B65/10
Filed: 1994-05-19
Abstract: PURPOSE: To provide a flying toy which is a flat plate when held by hand, but becomes a solid consisting of truncated pyramids when flying by bringing the rims of the bottom plates of two truncated pyramids into contact with each other to make a calyx and connecting both ends of an elastic string at symmetrical positions in the diameter inside the calyx. CONSTITUTION: The calyx pieces of upper/lower pyramid members 9, 19 are adhered to each other, and the calyx pieces of engaging pieces are adhered. And both end of a rubber string 24 are engaged with engaging grooves 8, 18. When enterual force pressing the top plates 1 of the flying toy is released (when a player removes the player's fingers), the engaging pieces are pulled by the teusile force of the rubber string 24, and side panels are moved in the vertical direction by means of folds, so that a truncated pyramid complex 29 is assembled. When external force in the direction 27 and 28 is applied to the top plates 1, the toy becomes flat. And when the external force is removed, the toy becomes a solid. Therefore, a player can throw the toy as a flat plate by giving external force to the toy, holding it by hand.  And the toy can be made to be slid automatically in the air by the tersile force of the rubber string 24.

Title: Device for attaching resistor unit
Inventor: NISHII NOBUYUKI
IPC: H05K7/12
Filed: 1987-04-30
Abstract: PURPOSE:To prevent water from gathering at a resistor unit and also prevent the imperfect contact of a connector because of corrosion of terminals even though water gets into a casing by causing the thickness of a substrate to be thicker than that of the casing and a terminal fixed part to protrude and also the whole surface of the substrate to have a form where its center part is high. CONSTITUTION:Resistors R, terminals 2 which fix the resistors R and connect with harnesses, and a substrate 1 which fixes the terminals 2 are prepared. The substrate 1 is attached to a mounting face of its substrate located at the periphery of an opening 5 so that the above resistor R protrudes from the opening 5 formed in a casing 4 of an air conditioner for automobile use into the casing. In such a structure, the thick ness of the substrate 1 is thicker than the plate thickness of the casing 4 and terminal fixed parts 1a fixing terminals 2 are prepared at the substrate 1 by projecting its parts 1a, and a protruding face of the substrate 1 protrudes so that its center part is high. In this way, water getting into the casing flows out on the resistor unit without gathering on the substrate and even if water droplets remain on the substrate, they gather at the terminal parts only slightly, and this situation prevents corrosion of the terminals.

Title: Burner for gas turbine
Inventor: KUMAKURA HIROTAKA
IPC: F23R3/12
Filed: 1994-05-20
Abstract: PURPOSE:To prevent the formation of an excessively thick region by strengthening a turning flow and to stabilize a flame by disposing a tuning flow guide having a tapered surface in a swirler cylinder between a guide blade protruding inside the cylinder and a combustion cylinder. CONSTITUTION:Compressed air to be supplied to a swirler cylinder 3 axially flows along the outer periphery of a combustion cylinder 2, and flows from a radial flow swirler 7 to the cylinder 3. The introducing air forms a turning flow (arrow) by guide blades 6. A turning flow guide 21 having a tapered surface 21A is provided at the cylinder 2 side of the opening of the swirler 7. Since the end 21B of the guide 21 prevents the flow of the air axially flowing directly from the opening, the introducing air from the opening all becomes the turning flow, and hence an axial flow is scarcely formed in the cylinder 2. The turning flow has a maximum flowing velocity at the small diameter part of the guide 21, and is lowered at the velocity as the diameter of the surface 21A is increased. Accordingly, the turning flow is maintained at the velocity in which fuel does not become excess around a fuel injection valve.

Title: Disk pad
Inventor: HARA YASUHIRO
IPC: F16D65/092
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To reduce generation of squeaks without lowering friction performance by providing notches of specified depths at both the ends except a specified range of the center part on the side which comes into contact with the friction member of back plate. SOLUTION: Notches 2 are provided at both the end parts except 50% or more of the center part on the side which comes into contact with the friction member 3 of back plate 1. The depths of the notches 2 are determined for a range of 0.2 to 1.0 mm. When notches formed at these both end parts exceed 50 %, a squeak suppression effect is eliminated. This disk pad can be obtained by performing a molding by a heating and pressurizing molding method and subsequently performing a heat treatment after a friction material composition is preliminarily formed into fixed thickness, next, inserting the back plate 1 provided with the notches 2 of depths of 0.2 to 1.0 mm at both the end parts into a metallic mould by turning the notch parts upward and a preliminary molding body is inserted on the back plate 1.  Thus, density of the tip part is lower than the center part, a squeak generation ratio is reduced and a product without the tip part can be obtained.

Abstract: PURPOSE:To weld automatically a weld line of a waveform radiation plate and an edge plate by interlocking a welding torch with a profile sensor which presses the waveform radiation plate and the edge plate by a flexible pressing body and moves along the weld line. CONSTITUTION:Welding is executed by determining a weld line by aligning a straight line part 20 of a profile sensor 19 with a side edge of a waveform radiation plate 1, operating a welding machine 22 by adjusting a welding torch 16 to match the weld line, and running a running truck 8. In this case, when the weld line is varied in the upper and lower directions, a variation quantity is informed to a control device 13 through a cord 24, and a vertical direction slider 12 is operated. Also, when the weld line is varied in the horizontal direction, a horizontal direction slider 11 is operated. Moreover, a hose 25 is deformed along a shape of the upper part at every bent part of the waveform radiation plate 1, and adheres tightly to an edge part 4 with a sufficient pressing force. Even if there is a stagger in the side edge of the waveform radiation plate 1, in case when a distance l between the tip of the welding torch 16 and the straight line part 20 of the profile sensor 19 is below the almost same as a distance between base parts of a space 6, a welding error caused by a fact that the weld line is dislocated is not generated.

Title: Discharge lamp exciter
Inventor: FUIRIPE DERON
IPC: H05B41/392
Filed: 1988-04-28
Abstract: PURPOSE: To make possible a stabilized current source, in which power consumption by itself is prevented in the case of any value of load, by using a direct current device and a relay device having a fixed frequency so as to excite a discharge lamp. CONSTITUTION: Switches I1 , I2 are formed so that one switch is closed when the other is opened. When the alternating current signal given to an input terminal 8 of a control means 7 is changed from a low level to a high level, the switch I1 is closed, and a power source U1 supplies the current i1 to an inductance L and a discharge lamp 1 through the switch I1 . The current i1 is increased from nearly zero to a preset reference value during the period Ta, and when the current i1 achieves the reference value, a comparator 11 gives the equivalent signal to the control means 7, and the switch I1 is opened, and the switch I2 is closed. Power, which is stored in the inductance L at a former stage, is discharged so as to generate the current i2 .  With this structure, a stabilized current source, which can supply a constant value of current independently of a load to be connected, can be obtained, and the power consumption by the switch itself is prevented.
