Patent JP-S5997335-A (JP)
Title: Buffer
Inventor: IIMOTO TERUICHI
IPC: F16F9/28
Filed: 1982-11-22
Abstract: PURPOSE:To prevent damage at an unexpected collision, by providing a plurality of cylinders different in inside diameter and fitted with pistons urged by restoring springs, and by coupling the cylinders to each other and providing a collision-receiving part on the piston for the first cylinder and a collision-receiving body fitting part on the piston for the last cylinder. CONSTITUTION:When a collision has taken place on a collision-receiving part 7, a piston 4 pushes oil 18 in a cylinder 2' together with a spring 8 because of an impulsive force, some of the oil 18 flows into a cylinder 2 through an oil hole 9 and the oil 18 in the cylinder 2 pushes and moves forth a piston 10. Since the cross-sectional area of the piston 10 is larger than that of the central cylinder 2', the thrust of the piston 4 is higher than that of the piston 10. The speed of the oil 18 flowing into an outermost cylinder 2'' through an oil hole 11 while being pushed by the piston 10 is reduced. The thrust on a piston 13 for the cylinder 2'' is lower than that on the collision-receiving part 7 so that the impulsive force to a collision-receiving body is very weak. Damage to the body or a person is thus prevented.

Filed: 1985-09-19
Abstract: PURPOSE:To permit the extremely quick formation of metallic oxide layers between welding glass positioned on both sides of a gap by immersing magnetic cores into a metallic alcoholate soln. CONSTITUTION:SiO2 films having 0.125mum thickness corresponding to half the gap width are formed by sputtering to the butt surfaces of a pair of the core blocks 1a, 1a shaped and worked to a prescribed size. The cores are butted and are tentatively adhered by a slight amt. of an instant adhesive agent; thereafter, the core blocks 1a, 1a are immersed into the metallic alcoholate soln. of ZrSiO2 as the essential component for final film formation so that the metallic alcoholate film is stuck thereto to 2-5mum. The blocks are then superheated for 30min at 150 deg.C to form the ZrSiO2 layers having 1-2mum film thickness as corrosion preventive layers 5. The cores having the ZrSiO2 layers are thereafter subjected to glass welding by welding glass and are thereby fixed. The time required for forming the thin metallic oxide layer between the welding glass is thus remarkably shortened.

The corrected luminance signals 7 are outputted to a resolution selecting section 3 which decides the bit to be selected of the luminance signal 7. A display controlling section 4 produces a control signal 10 required for making a display and, at the same time, outputs the control signal 10 and displaying picture data 9 to a displaying section 5. Since the resolution of the luminance signals 7 and the bias value added to the luminance signals 6 are made variable, it becomes possible that the luminance signals 6 can be displayed in corresponding to prescribed displaying gradation. In addition, a display having a degree of freedom and another display which can express a delicate color change become possible.

Abstract: PURPOSE:To improve the sintering performance while enhancing the mechanical strength and magnetic characteristics furthermore by employing an Nd(neodymium) based rare earth magnetic alloy and a rare earth group alloy, i.e., an Nd-Fe-B based alloy having low dissolution temperature. CONSTITUTION:A powder mixture principally comprising 8-40atm% of rare earth magnetic alloy containing Nd and Dy, 2-30atm% of B, and 0.15wt.% or less of O(oxygen) is subjected to wet forming under a pressure of 1.5ton/cm<2> in a magnetic field of 12 kOe and immediately sintered at 1000-1100 deg.C for 1-4 hours in argon atmosphere and then heat treated at 800 deg.C for about 2 hours. A permanent magnet thus produced has Nd-Fe-B based magnetic alloy phase 2 where the grain boundary is filled with a rare earth group alloy phase 3. Since the Nd-Fe-B based magnetic alloy phase 2 is surrounded by the rare earth group alloy phase 3 in the texture, mechanical strength of the permanent magnet can be enhanced without sacrifice of the magnetic characteristics.
