Abstract: PROBLEM TO BE SOLVED: To provide a metal electrode structure of a p-type InP compound semiconductor, having high ohmic characteristic in which a thin reaction layer can be formed at the same time as with an n-type semiconductor electrode through a low-temperature heat treatment of 400 deg.C or lower. SOLUTION: An ohmic electrode is constituted in a multilayered structure, formed by sequentially depositing a plurality of metal layers containing a first layer 21 composed of a transition metal, a second layer 22 composed of Zn, a third layer 23 composed of a transition metal on a single-crystal p-type InP compound semiconductor substrate 1. In the electrode, in addition, a film can be formed together with an n-type semiconductor electrode through low- temperature heat treatment of <=400 deg.C after the metallic layers are deposited. This p-type ohmic electrode 2 can be formed on the substrate at the same time as with the n-type ohmic electrode at a low heat-treating temperature of 400 deg.C or lower.  In addition, since the contact specific resistance of the electrode 2 is small at 10<-5> Ωcm<2> and a reaction layer has a uniformly small thickness of 0.1 μm or less, a metal electrode of an InP compound semiconductor can be obtained which is for higher in practicability and reliability, as compared with the conventional p-type ohmic electrode.

IPC: B62D6/00
Filed: 1992-02-05
Abstract: PURPOSE:To perform return operation of a handle at a constant feeling by a driver regardless of the magnitude of a road surface friction factor. CONSTITUTION:A torque sensor 31 detects torque exerted on a steering shaft 12 and an steering angle sensor 32 detects the steering angle of a handle 11. A microcomputer 33 decides reference self-aligning torque based on a detected steering angle.

When the road surface friction factor is low, output torque of an electric motor is widely controlled based on a decided result, and when the factor is high, the output torque is controlled in a narrow range. When the road surface friction factor is low and self-aligning torque exerted on a steering shaft is small, an assist force of an electric motor 22 to perform return operation of a handle is increased.

Filed: 1988-01-29
Abstract: PURPOSE:To obtain the developer layer forming device having a long life with a simple constitution by facing the guiding part of a developer layer thickness specifying member to the rotational direction upper flow side of a developer carrier and pressing the part in the vicinity of boundary part between the thickness specifying part and guiding part to the surface of the developer carrier. CONSTITUTION:The guiding part 1b of a developer layer thickness specifying member 1 and the circumference surface of a developer carrier 4 form a space in a 'wedge shape'. A developer 11 rushes into the wedge shaped-space together with the rotation of the developer carrier 4 in an arrow direction and pushes up the guiding part 1b. Then, a gap is made between the thickness specifying part 1a and the circumference surface of the developer carrier 4 and the developer slips through this gap. Then, a developer layer is formed in the lower flow side of the rotational direction of the developer carrier 4 from a pressing point 12. This gap is determined by the grain diameter of the developer 11 and pressing force F of the developer layer thickness specifying member 1 and the pressing force F can be obtained by the dead weight of the developer layer forming device itself and the adding force of a coil spring 5 which is a pressing and energizing means. Thus, the life of a constituting member is prolonged and the clear picture having high definition can be obtained.
