Title: Vibration damper
Inventor: AKIMOTO MASAO
IPC: F16F15/04
Filed: 1979-05-21
Abstract: PURPOSE:To sufficiently buffer an impulsive force and damp the vibration of a machine, by applying no resisting force when a vibration-restricted body moves in one direction first and applying a frictional force to the body when it moves in the other direction and almost stopping the body when it returns to the original position. CONSTITUTION:When a vibration-restricted body 15 is moved down by an impulsive force caused by a machine 10, a vibration restricting membmer 36 is moved down along slopes 30, 31, 37, 38 by a frictional force on a friction plate 41. Since the frictional force between the friction plate 41 and an end face 32 is very weak, the member 36 is moved down without suffering from resistance. When the vibration-restricted body 15 is moved up, the vibration restriciting member 36 is strongly thrusted onto the end face 32 and a high frictional force is caused between the end face 32 and the friction plate 41. The vibration-restricted body is thus prevented from vibrating up and down.

Abstract: PURPOSE:To enable quiet checking of gear position whether a gear shift is actuated in accordance with a specified command signal or not by executing it under specified conditions when change-over is executed to a maintenance operation mode with a maintenance switch. CONSTITUTION:A shift control unit 18 is changed over to a maintenance operation mode when a maintenance switch 28 is turned ON, and a command for shifting any one of transmission 5 gears to a neutral position is output as a shift control signal SF. It is checked according to a gear position signal GP whether the transmission 5 is shifted to the specified neutral position by means of the signal SF, and if the judgement id NO, an error display is carried out. Further checking may be done with respect to the fifth, sixth position or all gear positions in addition to the neutral position. It is thus possible to perform gear position checking if necessary without waiting time at start-up and uncomfortable noise can also be obviated.

Filed: 1987-03-17
Abstract: PURPOSE:To improve the electrical and optical characteristics of a thin semiconductor film by heat treating, cooling a buffer layer, and heating it at a growing temperature. CONSTITUTION:A buffer layer 20 of the same material as that of a thin semiconductor film 30 is grown at a temperature lower than 100 deg.C or higher than the optimum growing temperature at which the single crystal of the film 30 is grown on a substrate 10, the substrate 10 is then heat-treated at temperature of the optimum growing temperature or higher, then cooled to a lower temperature than the growing temperature of the layer 20, and the film 30 is thereafter grown at the optimum growing temperature on the layer 20. A thermal cycle of annealing the layer 20, then cooling it and again heating it at the time of epitaxially growing is conducted to redistribute a dislocation generated due to an erroneous fitting of the substrate 10 to the layer 20, thereby recomposing the crystal. Thus, the film 30 having preferable surface homology can be obtained with less dislocation.
