Filed: 1979-10-03
Abstract: PURPOSE:To perform guide service proper to passengers, by receiving station name information in running by the transmission line laid around the station and by detecting the start of the vehicle in the preceding station on the basis of presence or absence of opening of the transmission line to start guide broadcast for the next station. CONSTITUTION:Antennas 20a and 20b for information transmission controlled by running control system 30 are laid in start station 11 and next station 10 respectively, and the circuit between the ground and the vehicle is constituted only in the station yard and a specific section. While the vehicle stops in the platform, station name information, the time, the driving mode command, the door direction command, and so on are transmitted from running control system 30 from antenna 20a. Information received from the receiving antenna in vehicle 1 are sent to information transmister and receiver 7, and the next station name, the arrival forecast time, and  so on concerning broadcast are stored, and control data for the driving device and  the door control device are taken in.

Title: Manufacture of substrate for integrated circuit
Inventor: SATOU AKINOBU
IPC: H01L21/76
Filed: 1982-07-21
Abstract: PURPOSE:To obtain Si islands insulated and isolated by a method wherein a poly Si is superposed on a single crystal Si substrate via a Si3N4 and a SiO2 and partially changed into porous state and then oxidized from the substrate side. CONSTITUTION:The Si3N4 11, SiO2 12, and poly Si 13 are superposed on the N type single crystal Si substrate 10. After polishing the substrate 10, P-layers reaching the Si3N4 11 are formed by applying a Si3N4 mask 14, the P-layers are all changed porous by anodic oxidation in HF, and successively oxidized, thus SiO2 15 of approximately the same area is obtained, accordingly the Si islands 10' insulated and isolated are completed. By this constitution, the crystal orientation of the substrate is not restricted, because V grooves are not provided, and therefore the element formation is enabled by utilizing every crystal surface. Since grooves are not provided, the generation of warpages and damages of the substrate reduces.

Abstract: PROBLEM TO BE SOLVED: To prevent a person from being shut in by stopping a vehicle transfer device by a controller in emergency when a rope member spread on an indoor wall of a carry-in/out parking lot room is pulled out. SOLUTION: A safety device is constituted by a wire W stretched along an indoor of a carry in/out parking lot room, a display prate 11 indicating that it is an operation part for emergency stop hung on the wire W, a limit switch 9, and a controller 20. When a person 10 shut in a carry-in/out parking lot room pulls the wire W in accordance with the display on the display plate 11, the switch 9 operates. Next, the controller 20 stops a transfer device 22 in emergency if it is in a drive condition when the switch 9 enters an operation condition and prevents the transfer device 22 from starting its drive even if it receives a drive command from a control panel 21 when the transfer device 22 is in a condition before drive. Consequently, cost can be reduced without necessitating an expensive member because the number of parts used is small and wiring construction work is simple and the safety can be improved because all operation possible scope in the carry in out parking lot room is wide.

Abstract: PROBLEM TO BE SOLVED: To make injection in an appropriate amount possible and to ensure soundness for anchorage by a method wherein a packer surrounding a wall surface of an underground anchorage part at a ground anchor insertion hole is formed of a coarse fabric, and particles of injected cement milk are exuded to the outside of the packer. SOLUTION: A packer 18 formed of a nylon fabric in a coarseness for letting cement particles exude is inserted into a bored hole 1 excavated into the ground 20, and a high-strength tension member 2 made of twisted carbon fibers is fitted therein. Then, cement milk is injected into the packer 18 by high-pressure injection, and the tension member 2 is anchored by pressurized contact to the ground 20. On injection of the cement milk, cement particles are allowed to exude to some extent, together with water, to the outside of the packer 18 to exist between the packer and the ground 20. In the case where cracks or the like are present at the ground 20, the cement milk is prevented from exuding excessively. After the cement is hardened, the packer 18 becomes a core member, heightening anchorage to the ground 20.  Thereby, quantitative control becomes possible for injection material and anchorage can be made certain.

Abstract: PROBLEM TO BE SOLVED: To obtain an interference signal stably by utilizing a luminous flux from a semiconductor laser oscillating in multi-mode as an interference luminous flux after a substantial optical path length difference is imparted partially to each other in one luminous flux. SOLUTION: A multi-mode semiconductor laser is employed in a light source LD and a reference reflective plane M is provided at the end face of polarization beam splitter prism PBS. Reflected luminous flux from the light source LD is condensed gently through a diffraction lens DL and directed to a probe- like prism NCP where it is split into two on the PBS plane. One luminous flux is reflected on the reflective film M at the end face of the prism and the other luminous flux leaving the side face of the prism is reflected on the side face of an object ARM 1. Each reflected luminous flux is returned back to the PBS and the wave front thereof is recombined. The wave optical length difference is close to zero on the optical axis and interference phenomenon takes place.  Luminous flux from the multi-mode semiconductor laser can thereby utilized as an interference luminous flux after a substantial optical path length difference is imparted partially to each other in one luminous flux.
