Title: Method for induction heating of flat rolled material
Inventor: SONOBE MANABU
IPC: H05B6/10
Filed: 1994-06-21
Abstract: PURPOSE:To heat a flat rolled material efficiently at the required temperature increasing curve by performing lap control when a lap is zero or greater, and performing frequency control when the lap is less than zero. CONSTITUTION:When a flat rolled material 5 is heated using an edge heater 1 by running a rolling line continuously, the width of the flat rolled material 5 projecting to each side from the ends of the heater 1 is defined as a lap L. When the lap L is in the range not less than 0, temperature is raised to the required value through lap control in which the lap L is adjusted. When the lap L is less than 0 and on the minus side, the ends of the heater 1 are aligned with the ends of the flat rolled material 5 to set the lap L at zero, and heating is carried out through frequency control in which a frequency is adjusted by adjustment of variable capacitor capacity. Therefore, leakage flux is small and effective magnetic flux that intersects the flat rolled material 5 can be increased, and thus overheating of a heating coil 4 can be prevented.

Abstract: PURPOSE: To decrease resonance frequency, thereby to lower the noise level of the blower, by a method wherein the change is given to the sectional form of the exhaust to fit in with the velocity distribution of the air flow, by the air flow formed by the impeller.  
     CONSTITUTION: The inside of the wall 1 of the exhaust is covered with the flexible and elastic diaphragm 2, an airtight chamber 3 is made between the wall 1 and the diaphragm 2, the intercoupling hole 4 going through the wall 1 of the exhaust and being open to the airtight chamber 3 is provided, and the hole 4 is connected with the pressure source outside. With this constitution, the wind-velocity distribution is produced at the mouth of exhaust during the fan rotating. In the part where the velocity is fast, the air will go out from the exhaust by pushing the diaphragm 2 away, but in the part where the velocity is slow, the diaphragm 2 is moved to the direction throttled toward the inside of the exhaust because the expansive force of the airtight chamber 3 surpassed the moving pressure of thw wind-velocity, the exhaust section is decided in the position where the exhausted air pressure and the expansive force of the airtight chamber 3 balances, and the exhaust is throttled to the form to fit in with the velocity distribution at the mouth of the exhaust. Thereby, the resonance frequency produced within the casing is decreased and the noise level can be lowered.

Title: Tire air pressure detecting device
Inventor: KUROYANAGI MASATOSHI
IPC: B60C23/02
Filed: 1989-06-26
Abstract: PURPOSE:To automate a return to the initial state during supplying of air by forming a wire pressure detecting device by a movable member having a magnetic material capable of moving by centrifugal force or vibration, a means for switching the movable member to a locked or loosened state, and means for detecting magnetic flux of the magnetic material to judge whether the magnetic flux is regular or irregular. CONSTITUTION:Air pressure in an internal air chamber 49 is increased or decreased by the tire internal pressure to expand or contrast a bellows part 51 to lock or loosen a magnet-presser part 53 and a cap 57 to/from a spherical magnet 55. When the spherical magnet 55 is loosened due to the tire pressure drop, it is moved at random by centrifugal force or vibration. A magnetism detecting unit 31 detects the movement of the magnet to judge the tire pressure drop. On the one hand, when air is injected, the spherical magnet 55 is locked to any position by the magnet-presser 53 and the cap 57. Thus, signals detected by the magnetism detecting unit 31 are stabilized during travelling so that it is judged whether the air pressure is normal or not. As a result, a return to the initial state is automated.
