Inventor: HOSHINO KAZUO
IPC: C21D6/00
Filed: 1981-01-28
Abstract: PURPOSE:To easily produce a high-carbon spare piece useful as a razor blade, by carburizing a relatively lower-carbon thin steel sheet. CONSTITUTION:A stainless steel containing 11.0-18.0% Cr and C<0.25% is formed into a stainless steel sheet having a thickness of 1.00mm. or less, by ingot- making, cogging and hot-rolling or by hot-rolling a continuously cast slab, followed by cold-rolling. The stainless steel sheet is carburized at a temperature of 850-1,050 deg.C in a carburizing method such as ion-carburizing or vacuum-carburizing, and then subjected to diffusion treatment in a nonoxidizing or reducing atmosphere such as CO while inhibiting decarburization, to let the steel sheet uniformly contain carbon in it. Thereafter, the steel sheet is annealed, and subjected to treatment involving at least one cold-rolling step with a reduction of 20% or more and annealing. Thus, the carbon content of the steel sheet can be easily controlled at a level necessary for a spare razor blade, and productivity is improved.

Filed: 1978-02-01
Abstract: PURPOSE: To prevent lost heating etc. through simple constitution, by providing a control unit which causes the calorific power applied to a heated matter to vary in inverse proportion to the temperature of the heated matter.  
     CONSTITUTION: Excitation windings 31∼33 are connected to an AC power source. Magnetic poles 11∼13 are excited to generate an alternating magnetic field. An eddy current is caused in a cooking vessel 4 by the varying magnetic flux of the magnetic field to heat the vessel to cook the heated matter therein. Supports 11b∼ 13b made of such a material of large thermal expansion coefficient and deformation as bimetal are partially fixed to the tops of the magnetic poles 11∼13. The supports 11b∼13b are thermally expanded and deformed according as the temperature of the cooking vessel 4 rises. As a result, the distance between the magnetic poles 11∼ 13 and the cooking vessel 4 increases and the calorific power applied to the vessel decreases.

Filed: 1998-01-22
Abstract: PROBLEM TO BE SOLVED: To accurately position an original plate on an original plate holder. SOLUTION: An original plate supplying platen 61 is opposed to the original plate holder 32, and can be deformed between a first posture to place plural original plates and a second posture to make the original plate placed on an uppermost part to be in a flat condition. A keeping means 62 can keep the platen 61 in the desired posture. As to the platen 61; at least the part 64 of the platen 61 is formed by using an elastically deformable elastic member. After the original plate on the platen 61 is pressed by the holder 32, so that the original plate placed on the uppermost part is made to be flat and also the platen 61 is projectedly curved downward; the deformation of the original plate is removed by separating the holder 32 from the original plate. Then the holder 32 comes close to the original plate, sucks and holds the original plate.  Thus, the deformation of the original plate is removed, so that accurate positioning can be performed with respect to the original holder.

Title: Synchronous-rectification dc-dc converter
Inventor: HENMI TOKUYUKI
IPC: H02M3/155
Filed: 1994-02-02
Abstract: PURPOSE:To obtain the synchronous-rectification DC-DC converter in which, when a load is short-circuited in a heavy load mode, a current for a light load rises immediately with the restoration of the load by a method wherein, when a synchronous rectifying element is set to continuity in the heavy load mode, a main switching element for a light load is turned off and a light-load control circuit having an overcurrent drooping characteristic is operated irrespective of the heavy load mode or a light load mode. CONSTITUTION:In a heavy load mode, a light-load control circuit 122 is utilized, a FET 5 is operated, a heavy-load control circuit 121 controls FETs 3, 4 so as to be turned on and off in such a way that a load voltage detected by resistances 9, 10 is kept at a prescribed value. At this time, the FET 5 is turned off during the ON- period of the FET 4 by an interlock circuit 123. When a load 11 is short-circuited in the heavy load mode, an overcurrent protective circuit 124 cuts off a power supply for the heavy-load control circuit 121 due to the voltage rise of a load-current detection resistance 13, and it turns off the FETs 3, 4. At this time, an overcurrent drooping circuit inside the light-load control circuit 122 functions, and a load current is limited to a prescribed current. As soon as the load 11 is restored, the light-load control circuit 122 is returned to an operation in a normal state.

Title: Switching power supply
Inventor: OGAWA TAKAHIRO
IPC: H02M3/335
Filed: 1999-01-19
Abstract: PROBLEM TO BE SOLVED: To prevent vibrating noise from a transformer from being heard even in an audible band, by setting the maximum current of a primary coil so as to be smaller than a value corresponding to a voltage error. SOLUTION: When the operation of load is placed in a standby condition, output 13 is set to an L level, and a transistor Q7 is turned off, so that divided voltage is applied to the base of a transistor Q6. As a result, switching of a switching transistor Q1 is controlled so that the voltage of DC output 12 may be approx. 1/3 of its rated value, and intermittent switching occurs because the load current of the DC output 12 becomes approx. zero. At the time of the intermittent switching, the voltage of a minus level generated at a path 21 becomes 1/3 that at the time of ordinary operation to meet the voltage of the DC output 12, and the maximum current of the primary coil L1 is limited, so that vibrating noise from the transformer 1 is suppressed. It is thus possible to prevent the vibrating noise from the transformer from being heard even in an audible band.
