PURPOSE:To provide the parts assembling device capable of heating and deforming a pin by a simple operation without the necessity of a special tool or an exclusive machine at low cost by using the rotary member provided with the recessed surface giving the friction heat caused by its rotation, making said rotary member to be in contact with the end part of the pin to be heated and deformed. CONSTI...

PURPOSE:To synchronously perform engagement of speed changing clutch and application of engine braking by operating the holding unit of a high speed transmitting system even when the speed changing clutch is released. CONSTITUTION:In shift down operation, a holding unit 24 is kept to operate from the starting point to the finishing point of said operation. A sub speed change gear 4 is held by a hi...

A nuclear fuel rod cladding having a burnable absorber integrally incorporated therein has an outer tubular layer of a zirconium alloy; an intermediate layer, of a thickness less than the outer tubular layer, of a zirconium alloy containing a boron-containing burnable absorber; and an inner layer, of a thickness less than the intermediate layer, of zirconium metal. The layers are bonded together t...

PURPOSE:To prevent the diterioration and destruction of an electrothermal converter element, by providing a predetermined bias power source to a head driving preparatory power source current supply means for supplying a current to the electrothermal converter element. CONSTITUTION:When a control circuit 6 receives the information of a recording information start signal, said circuit 6 supplies a '...

A flexible stick tank gauge is made of a thin metal or plastic tape. The tape is sufficiently thick to be self-supporting when held vertically from the lower end. Alternatively, the tape is curved to be a narrow sector of a cylinder. Measuring indicia are applied to at least one surface of the tape. The tape remains flexible at extreme environments of temperatures and will not break in normal use ...
