Title: Scaffolding board
Inventor: ONO TATSUO
IPC: E04G5/08
Filed: 1995-06-30
Abstract: PURPOSE: To facilitate connection and disassembly between a baseboard and a plate body through the simple operation of a locking bar member by making the baseboard removable from the plate body through a locking bar device. CONSTITUTION: A locking bar device 19 has a fixed plate 21 provided with a mounting member 20 that can be inserted into a locking bar hole 15. Baseboards 7 are erectly placed at lateral ends of a plate body 6, and at this time, the mounting member 20 is inserted into the locking bar hole 15. In this inserted state, the base board 7 is inclined slightly inward to make the lower end of the mounting member 20 coincide with the insert hole 18 of a reinforcing rib 14. In this coinciding state, the baseboard 7 is returned outward again to fit the mounting member 20 into a slip-off stopper hole 16. As a result, a plate body around the slip-off stopper hole 16 is engaged with slip-off stopper cutouts 25, so that the mounting member 20 is regulated in the vertical movement.  After erecting the mounting member 20 vertically, the head of the driven piece 27 of a locking bar member 26 is driven to insert the lower end into the locking bar hole 15.

Title: Centrifugal impeller
Inventor: IWATA ATSUSHI
IPC: F04D29/30
Filed: 1998-07-03
Abstract: PROBLEM TO BE SOLVED: To relieve the centrifugal stress during the operation of the impeller and improve the strength thereof, by heating the entire impeller and then quickly cooling only the circumferential portion of the core plate, generating local elastic deformation in the inner peripheral portion by the heat stress which is generated during the quick cooling, thereby generating residual stress of compression. SOLUTION: In a device that applies residual stress, an inner peripheral portion of an impeller comprising a core plate 1 and a vane 2 is cooled by cooling water passed by a piping 3 inserted therein. A jig 4 is mounted near the outer peripheral portion of the core plate 1 for heating it with a high frequency current, and a jig 5 is mounted near the vane 2 for heating it with a high frequency current. When the inner peripheral portion of the impeller is cooled and the outer peripheral portion is heated with this device, temperature difference occurs between the inside and outside of the impeller. As results, a tensile stress is generated in the inner peripheral portion, while a thermal stress of compression stress is generated in the outer peripheral portion.  With increased difference in temperature, the tensile stress in the inner peripheral portion exceeds the yield point, and an elastic deformation occurs. If the temperature is lowered to the ordinary temperature in this state, a residual stress of compression remains in the inner peripheral portion.

Abstract: PURPOSE:To prevent the breakdown of a transistor and the malfunction of a circuit by giving a medium potential between the maximum potential and the minimum one to one or more input terminals. CONSTITUTION:In a monolithic integrated circuit composed of a plurality of circuit blocks, one or more of the signal input terminals belonging to one or more of the circuit blocks are fixed at the medium potential.

Title: Braking liquid pressure controller for automobile
Inventor: KOSAKAI ASAO
IPC: B60T7/12
Filed: 1996-07-18
Abstract: PROBLEM TO BE SOLVED: To set an effective threshold valve even in the degradation of a vehicle by calculatively comparing a present regression formula previously calculated with a new regression formula related to master cylinder pressure and a brake pedalling amount calculated newly to correct the threshold value of brake pedal pedalling speed from the result of the calculation. SOLUTION: When a braking liquid pressure controller 1 closes an ignition switch, an electronic controller 29 carries out the initial check of early setting. The electronic controller 29 takes in the input data of a brake pedal pedalling amount sensor 36, and calls up the threshold value of preset brake pedal pedalling speed to be compared with the brake pedal pedalling speed. If the brake pedal pedalling speed exceeds the threshold value of the brake pedal pedalling speed, the operation of the brake pedal 17 is judged to the quick brake operation, and if it does not exceed the threshold value, the operation of the bra pedal is judged to be the normal brake operation. Thus, a value liable to correspond to the threshold value of the brake pedal pedalling speed can be set even after the degradation of a vehicle.

Abstract: PROBLEM TO BE SOLVED: To realize a steel plate monometallic can which is excellent in can openability and corrosion resistance by a method wherein the cross sectional shape of a cutting guide groove at an opening piece edge part is made a structure having a thinner part, and having a notch part which is shallower than the plate thickness on the can external surface side of the thinner part, at a certain part or the total part of the cutting guide groove total length. SOLUTION: When a cutting guide groove 3 is formed, a press-forming is performed for a metal plate using top and bottom dies having a shoulder part with a protruding smooth curved surface at a location corresponding with the shape dimension of an opening piece 2. After forming a thinner part wherein the plate thickness is gradually changed, a pushing- back work is performed. Then, a press-work by a sharp blade is performed at the thinner part where the plate thickness is gradually changed, and a shallow notch is placed. The depth of the notch is desirable to be 20% or lower of the metal plate thickness. At the time of can opening, a first breakage arises at the notch part, and the can opening advances by a propagation of the breakage.  Since a light pressing work by the sharp blade is performed at the pressing work, the problem of a tool life in a conventional method by a sharp blade only, and the reduction of corrosion resistance due to the exposure of iron when a steel plate is used as the raw material can be improved.
