Title: Method of continuous growth of super-lattice structure of distortion layer
Inventor: KEISU JIEE RINDOBAAGU
IPC: C23C16/44
Filed: 1988-08-26
Abstract: PURPOSE: To continuously stick a silicon layer and a germanium layer on a substrate by periodically changing the concentration ratio of silicon and germanium existing in a material gas atmosphere in a reaction furnace, and exposing the substrate to the atmosphere. CONSTITUTION: A silicon slice is loaded on six faces of the periphery of a susceptor 12, rotated in a reaction furnace 10, and heated with an induction coil on the outer periphery. Material gas SiH4 and GeH4 in a hydrogen atmosphere flows toward the inside of the reaction furnace 10 through two nozzles 14, 15. The sticking speed of silicon changes in accordance with the change of gas boundary layer thickness. The change ratio is different from that of germanium. The formation of the susceptor 12 changes periodically the wt.% of germanium to be stuck on a silicon substrate. When thin film composition is examined, the atomic wt.% of germanium in lattice exhibits sinusoidal change.

Title: Semiconductor-type acceleration sensor
Inventor: HAYASHI MASAHIDE
IPC: G01P15/125
Filed: 1994-09-06
Abstract: PURPOSE: To diagnose a failure of an acceleration detector at all times by externally setting a measuring mechanism for diagnosing a failure of a cantilever or the like to the acceleration detector. CONSTITUTION: A light-emitting element part 21 and a light-detecting element part 22 of a diagnosis output-detecting part 2 are arranged below a movable electrode 8 of an acceleration-detecting part 4. When a cantilever 13 is inadvertently cut and dropped, a light output from the light-emitting element part 21 is shut by the movable electrode 8, and therefore amount of light input to the light-detecting element part 22 is changed. A failure of the acceleration- detecting part 4 is diagnosed from the change of the amount of light. Since an output of the diagnosis output-detecting part 2 detecting the failure is input to a control unit 3 in a different system from the acceleration-detecting part 4 because of a circuit structure, the circuit serves as a fail safe circuit when applied to an air bag or the like.

Abstract: PURPOSE:To reduce the power necessary for transfer of works by absorbing a plate-shaped work on a carrier conveyer through an absorber of an elevator with a balancer that runs on the upper rail between a carrier conveyer and an discharge conveyer, and by transferring the work to the discharge conveyer. CONSTITUTION:A work drawing device 4 runs along two rails 5 on a lateral frame material 25 supported by struts 24 on both sides of a carrier conveyer 2 and a discharge conveyer 3. An elevator 9 provided with a balancer 12, a lifting tool 7 and an absorber 10 are mounted on a running board 6, and the work drawing device is thus formed. The running board 6 comes to the upper part of the conveyer 2, and the lifting tool 7 is lowered by the elevator 9, while a work 22 on the uppermost plate-shaped work 23 put on the conveyer 2, is absorbed by the absorber 10 and is thus lifted. The running board 6 runs up to upper part of the conveyer 3, and the lifting tool 7 is lowered by the elevator 9, so as to cancel the absorption, and the work is put down on the conveyer 3. The process is repeated, so as to transfer the work from the conveyer 2 to the conveyer 3. The transfer can thus be carried out at small power.
