Title: Method for hot-rolling shape
Inventor: UDAGAWA TATSURO
IPC: B21B27/02
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To manufacture a product having different flange widths from rough shape billets having the same shape with respect to a wide-flange shape and shapes similar to that by reducing the flange width of a rough shape billet after rolling for forming to the flange width corresponding to the shapes having different sizes by greatly edging the flange width by edger rolling in a rough rolling stage. SOLUTION: The rough shape billet 31 having the flange width of leg length Ho which is rolled with a forming mill on the hot rolling line for manufacturing the shapes is greatly reduced to a leg length He corresponding to the different size in the rolling stage with a universal roughing mill group consisting of a universal mill and edger and the flange width of the rough shape billet is reduced. For example, using rolls for forming the rough shape billet in the forming mill, the rough shape billet 31 for the wide flange shape of H600×300 is rolled into the leg length Ho and, next, the flange width is greatly reduced into the leg length He equivalent to H600×250 with the edger in the rough universal rolling stage and, after that, the universal rolling is executed and the product of H600×250 is obtained.

Title: Frequency scan type multi-thermometer
Inventor: TAMADA NORIJI
IPC: G01K13/00
Filed: 1989-12-25
Abstract: PURPOSE:To enable measurement of a temperature at a plurality of positions by two measuring lines by a method wherein a plurality of temperature detecting circuits are connected in series or in parallel and the temperature detection circuits are each provided with an oscillator for applying a voltage and a detector for obtaining temperatures at points from a resonance frequency. CONSTITUTION:When an oscillation frequency f0 of an oscillator 5, namely, a signal from an F/D converter 6 is taken on axis of abscissa and a voltage across a load detection resistor 4, namely, a voltage V from a detector 8 on axis of ordinates to plot, a change in impedance occurs at a point where the oscillation frequency f0 coincides with resonance frequencies f1 - fn at parts of temperature detection circuits 1a - 1n, causing a decrease in the voltage V across the resistor 4. As the frequency at this point corresponds to temperatures at the parts of the circuits 1a - 1n, the measurement of temperatures at a plurality of positions can be observed as change in frequency even with two lines for measurement. In other words, the solid line indicates an output in a distribution of the temperatures. But when the temperature distribution changes, an output is obtained as indicated by the broken line. When dependence on temperatures at resonance parts is known, a temperature distribution can be determined.

Inventor: KOBAYASHI HIDEO
IPC: F02F1/42
Filed: 1992-12-16
Abstract: PURPOSE:To secure both of heat insulation property at starting of an internal combustion engine and heat conductivity during continuous driving of the internal combustion engine, to suppress excessive temperature rising of exhaust gas, and to provide the exhaust port structure of the internal combustion engine advantageous to suppress overheat and deterioration of catalysts and exhaust system parts. CONSTITUTION:An exhaust line 3 is fitted in the exhaust port 12 of a cylinder head 1. The exhaust liner 3 has a cylindrical steel liner main body 30 and a thin-walled support 33 linked to both ends in the axial direction of the liner main body 30. A micro-gap 5 which functions as a heat insulation air layer is formed between the outer circumference 30c of the liner main body 30 and a port internal circumference 12a. In the case of continuous driving of the internal combustion engine, heat expansion of the liner main body 30 in the radial direction becomes larger, the micro-gap 5 disappears, and the outer circumference 30c sticks to the port internal circumference 12a so that heat conductivity increases and temperature of exhaust gas is accelerated to drop.

Title: Method for controlling stage rising of time recorder
Inventor: TAMURA TOSHIYA
IPC: G07C1/00
Filed: 1987-12-29
Abstract: PURPOSE:To prevent the damage of parts and the danger of a fire by stopping a stage rising action when a reference position detection switch is not actuated, even when it reaches the number of stages set beforehand during the action of successive stage rising. CONSTITUTION:When a stage rising rack 54 reaches a top stage, drops and a referrence position is detected by a limit switch 72, the limit switch 72 turns to 'yes', the operation of the number of stage rising is executed and the number of stage rising L is calculated. When whether it is L=0 or not is asked and 'no' is replied, the stage is risen by one stage, when the limit switch 72 still remains the condition of 'on' at that time and it is 'yes', since it means that the limit switch is defective, the stage rising is stopped and simultaneously it is informed that the limit switch is defective. Thus, the heat generation of a solenoid 56, a transformer and the like is suppressed and the damage of parts and the danger of a fire can be prevented.

Inventor: KUDO HIDETOSHI
IPC: F02B31/02
Filed: 1997-12-08
Abstract: PROBLEM TO BE SOLVED: To enhance combustibility in time of stratified combustion, and improve fuel consumption and emission by making the rotational direction of a swirl of an injector, seeing this injector from the side of a base end part, different from that of the swirl seeing a combustion chamber from the side of a cylinder head each other. SOLUTION: An injector 18 is set up in and around an interval between both inlet ports 12 and 12 at the peripheral edge of a combustion chamber 10 of a cylinder direct injection engine, and its fuel injection axis 26 is nearly accorded with that of the injector 18 itself, while it is set up so as to make it obliquely cross with a cylinder axis 25. In brief, in time of looking from a direction of this cylinder axis 25, the fuel injection axis 26 is set up so as to pass through the center of the top of a piston 5. Then this injector 18 is installed with a swirler in the tip part, but the rotational direction of this swirler in time of seeing the injector 18 from the side of a base end is set up clockwise. With this, a local air-fuel ratio in and around a spark plug 22 is made to be a yet properer value, thereby making improvements in combustibility in time of stratified combustion.

IPC: F04D25/08
Filed: 1996-11-13
Abstract: PROBLEM TO BE SOLVED: To utilize the space in a room effectively, improve an appearance beautifully, and eliminate trouble of cleaning and storing works by housing a gear box and a motor for oscillation swing into a cabinet, and tightly housing a main body on a construction material such as a wall when an electric fan is not used. SOLUTION: An arm 2 is installed on a wall by a plate 3. A main body 1 and the wall are connected to each other by the arm 2. When an electric fan is used, the main body 1 which is tightly fitted to the wall is pulled up, and the fan is used. When the fan is not used, the main body 1 is pushed toward a wall side. The arm 2 is contracted, the arm 2 and the plate 3 are hidden by the cabinet of the main body 1, and the cabinet of the main body 1 is tightly fitted to the wall. When a shutter 9 arranged on the surface of the cabinet is closed, blades and a blade driving motor are also hidden. It is thus possible to utilize the space in a room effectively, improve an appearance beautifully, and eliminate trouble of cleaning and storing works.

Title: Winding machine
Inventor: HAGA MASAYOSHI
IPC: H01F41/06
Filed: 1999-11-29
Abstract: PROBLEM TO BE SOLVED: To enable long setting of a conductor wire at a connection part for coil connection and also enable increased clamp reliability, when a tip end of the conductor wire is clamped to a winding frame of a winding machine. SOLUTION: A coil is made by winding a conductor wire around a winding frame. A clamp claw 110 is moved in a direction along one side of a flange of the winding frame, and the tip end of the conductor wire extruded from an induction groove 108 is pushed against the winding frame 1, while being bent. The conductor wire is clamped in the direction along one side of the flange, that is, bent in the frame-rotating direction. Due to bending in the frame rotating direction, even the long connection part at the tip end of the wire will not disturb the rotation of the winding frame. The bending in the frame rotating direction causes the wire to be reliably fixed. Furthermore, since the wire is guided along the induction groove 108 up to a the clamp position, the wire can be clamped automatically, thus reducing manual works.
