IPC: G01S13/60
Filed: 1996-07-03
Abstract: PROBLEM TO BE SOLVED: To reduce the influence of cross talk between Doppler sensors in reception of a reflected wave from a road surface so as to detect a vehicle moving direction with high precision. SOLUTION: A pair of an emitter and a wave receiver in each of two Doppler sensors are arranged in the mutually different horizontal direction as to an optical axis 126 of a lens 122. In the respective positions, an emitter 106 and a receiver 110 complying with the Ldirection and an emitter 107 and a receiver 111 complying with the R-direction are arranged so that the minor axis directions of the openings of respective open-end wave guides constructed of the respective pairs cross each other orthogonally. As the electric field face of an electric wave is parallel to the minor axis direction, polarized waves of the both Doppler sensors cross each other orthogonally, so that distinction and elimination can be carried out even when one of the reflected waves is mixed in the other, and as a result, high measurement precision can be provided.

     CONSTITUTION: A heat pipe is composed of an evaporation area 1, heat insulation area  2, condensing area 3, heat transmitting part 4, heat insulation area 5, evaporation and  condensing area 6, and control part 7. When a temperature at the control part 7 is  higher than that of the condensing area 3 and lower than that of the evaporation area  1, the working fluid vapor is liquified only at the condensing area 3, and the condensed liquid is moved into the evaporation area 1 and during this flow of the liquid,  a heat transmission is performed between the evaporated liquid 1 and the condensing  area 3. In the control part 7, the condensed liquid of the working fluid and the vapour  are kept balanced, and so a holding volume of the working fluid at the control part 7  is not increased or decreased. When the control part 7 is cooled, a part of the vapour  generated at the evaporation area 1 is condensed at the control part 7, a volume of  working fluid at the heat transmitting part 4 is decreased and a capability of heat  tramsmitting operation is decreased.

Filed: 1983-09-22
Abstract: PURPOSE:To shorten the control processing time of an action sequence by providing a means which stores the unit action needed for start decision of the action sequence including synchronization or exclusion and deciding the start of the stored unit action when an action which should receive the decision of start is checked. CONSTITUTION:An integrated controller 30 has an integrated control memory 31, and robots 11 and 14 are controlled via robot controllers 32 and 33 respectively. The memory 31 contains high-speed processing tables 200-202, and tables 200 and 201 serve as stack tables with the table 202 serving as an action NO-synchronous/exclusive step NO relation table respectively. When either one of tables 200 and 201 is set under a read mode, the other one is set under a write mode. The control part 30 decides the synchronous/exclusive start for each action of plural facilities according to the action sequences stored in tables 27-29 of the memory 31. Then unstartable actions are set under the write modes. In such a way, the start is decided only with the unit action which actually requests the decision of start.

Filed: 1990-06-29
Abstract: PURPOSE:To prevent production of an error in a pipe length after cutting even when a pipe is moved during the starting of cutting by suspending cutting to reset a scale, moving backward a cutting means, and effecting recutting until a feed amount measured by a scale coincides with a necessary feed amount based on an actual measurement pipe length. CONSTITUTION:After the one gas cut surface of a short pipe 4 is finished, the other gas cut surface 4a is pointed to a main spindle rest 2 and set. Through drive of the main spindle rest 2, the gas cut surface 4a is cut by means of a cutting blade 1. After the gas cut surface 4a is cut to an extent that the mill scale of the gas cut surface 4a is removed, cutting is stopped at a feed surface 4b once, and a magnetic scale 3 is reset to move backward the main spindle rest 2. A length (y) between a primary cut surface 4b and a final finish surface 4d is actually measured, and from the length and a final finish length (x), a cutting feed amount alpha during recutting is determined, The cut feed amount is inputted to the controller of the main spindle rest 2 to start recutting, and when the forward cut value of the magnetic scale 3 attains the cut feed amount alpha, a cutting feed is automatically stopped.

Abstract: PURPOSE:To protect a car from potential damage and drop when a car or its loadage exceeds a specified value. CONSTITUTION:A lift base E consists of a lift fork 1 and a lift fork fixing member 2. A car length sensor 7 a car width sensor 8 are laid out around a lift space on the ground surface.

IPC: H01L31/107
Filed: 1983-09-21
Abstract: PURPOSE:To make high speed response feasible by a method wherein a buffer layer meeting specific requirements is laid between a light absorbing layer and an avalanche layer. CONSTITUTION:A buffer layer 4 with the difference DELTAEc of conductive band disconnection to a semiconductor comprizing a light absorbing layer larger than the difference DELTAEv of valence electron band disconnection is laid between a light absorbing layer 2 (InGaAs) and an avalanche doubling layer 3 (InP). In case of an actuation as shown in Fig. (b), electrons will be accumulated on the avalanche layer side interface due to the conductive band disconnection between the avalanche layer 3 and the buffer layer 4 to impress the interface between said two layers 3 and 4 with high electric field. The band of the interface between the avalanche layer 3 and the buffer layer 4 is bent so that the tunnel transmission of the hole carriers accumulated in the buffer layer 4 may be made easier to relieve the accumulating effect of the hole carriers. Therefore the conventional deterioration of high speed response may be improved.
