Title: Brake control device for rolling stock
Inventor: MARUTA YOSHIMI
IPC: B60T13/58
Filed: 1995-04-20
Abstract: PURPOSE: To make whole device construction simple and small by shutting off a capture command from a brake demand operating device to an electropneumatic change valve when the demand operating device or its power supply goes in failure, also actuating an emergency brake system, and supplying a pressure to a brake cylinder. CONSTITUTION: When a failure has arisen in a power supply or demand operating part 11 of a brake demand operating device 1 equipped with a monitoring circuit 2 followed by actuation of a plurality of sensors, normally closed contacts 16, 17 of a switch 6 are opened. A capture command F is separated from an electropneumatic change valve 5 and its output nullifies. An emergency brake command E2 is shut off to actuate application of an emergency brake, and specified pneumatic pressure for emergency brake is fed to each brake cylinder BC1-BC4. Further a demand operating device normal signal N to a coast preventing device 21 nullifies. Thereby a backup brake force is generated by a simple control method using an existing emergency solenoid valve EBV and coast preventive valves SV1-SV4, which allows simplifying the configuration of a backup brake controlling circuit.

Furthermore the points are complemented and corrected in order to define the overlapping part between the segments of adjacent loops set in the deviation within a fixed distance as the same segment. This segment is outputted to a 5th work memory 2-5. In such a way, the road network data is produced automatically.

Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To detect a minute displacement of a ground surface as it has a danger of landslide from a safe remote point with high precision by comprising a monitor means fixed to a steady area and a radio reflecting means fixed within a danger area. SOLUTION: This surface layer displacement detecting device is provided with, for example, a monitor means 10 having a transmitting and receiving antenna 12, which is fixed to a steady area 1 through a support base 11, and a radio reflecting means 12 such as a Luneberg lens, which is fixed to a pile 4 driven into a surface layer displacing area 2. The monitor means 10 transmits a transmitting wave ft which is a micro wave having a prescribed wavelength λin beam form, receives the reflected wave fr from the reflecting means, and composes it with the transmitting wave ft. Since the amplitude of the composed wave is changed from the maximum value to the minimum value within λ/4, the distance between the monitor means 10 and the reflecting means 13 is properly preset, whereby a minute moving distance can be detected.  In order to remove the background noise, the reflected wave may be modulated by the reflecting means 13.

Title: Vapor-phase etching for compound semiconductor
Inventor: KASAHARA JIRO
IPC: C23F4/00
Filed: 1985-06-05
Abstract: PURPOSE:To contrive to clean the surface of a compound semiconductor and to contrive to improve the crystallizability thereof by a method wherein a heat treatment is applied to the compound semiconductor at temperatures higher than the prescribed temperature in an atmosphere of hydrogen and a vapor-phase etching is applied to the compound semiconductor. CONSTITUTION:A heat treatment is applied to a GaAs compound semiconductor for 30min in mixed air current, wherein arsine (AsH3) is mixed in hydrogen (H2) in a trace amount, then a vapor-phase etching is applied to the GaAs compound semiconductor at 800 deg.C or more. Here, the reason for mixing the AsH3 in the H2 is because the vapor pressure of the elements of the V Group is higher compared to that of the elements of the III Group in III-V compound semiconductors, such as the GaAs compound semiconductor, so when a longtime heat treatment is performed at high temperatures, a phenomenon that the As, one of the elements of the V Group, is excessively dissociated and thermal pitches generate on the surface of the compound semiconductor is prevented from generating. When a vapor-phase etching is performed at temperatures higher than 800 deg.C or more, an etching amount of about 30Angstrom  or more can be obtained. By this way, the attachments on the surface of the GaAs compound semiconductor are removed and the crystallizability of the GaAs compound semiconductor can be improved. Moreover, as an etching is performed in the epitaxial growth device, an epitaxial growth can be performed without taking out the substrate outside the device after the etching. As a result, the substrate is prevented from being subjected to oxidation and so forth. This etching method is more efficient.

IPC: G01B11/28
Filed: 1987-05-19
Abstract: PURPOSE:To measure an area so that a variance is scarcely generated in a measured value, and also, to miniaturize the instrument, by constituting the photodetecting surface of an insulating substrate, of a closed circuit of two terminals formed by a linear pattern of a photoconductive substance. CONSTITUTION:On an insulating substrate, the photodetecting surface is formed by drawing a linear pattern, for instance, of 0.1mm thickness and 1mm width of one stroke writing. In this state, first of all, the whole photodetecting surface is darkened and measured by an electric resistance meter 5 connected between electric resistance measuring terminals 4, 4 of a linear pattern of a photodetecting part 3. At this time, the physical property of a photoconductive substance and the illuminance of a dark time are adjusted so that an electric resistance RD becomes about 10MOMEGA. Subsequently, by radiating an irradiation light to the whole photodetecting surface, an electric resistance R of the linear pattern is measured 5. In this case, a graphic 7 which becomes an object to be measured is brought to an image formation as a shadow 8 on the photodetecting surface, and other part is irradiated brightly. By substituting the resistance R across the linear pattern of this time, the resistance RD of a time when it is dark, and an area A(=0.01m<2>) of the photodetecting surface, in the place of S=A.R/ RD, an area S of the graphic can be derived.

Filed: 1988-05-18
Abstract: PURPOSE:To prevent a stepping motor from stepping out making an actuation frequency lower when a stop is driven in an open state than when the stop is driven except from the open position. CONSTITUTION:The number of stop stages is converted into the number of driving steps of the stepping motor by a clock circuit 32 and a distributing circuit 33. A stepping motor driver circuit 34 determines which of coils 12 and 13 is powered on according to said number of steps to rotate the stepping motor by an optional quantity. In such a case, the actuation frequency is made lower when the stop is driven in the open state than when the stop is driven except from the open position (Start pulse intervals are made long). Consequently, the stepping motor is prevented from stepping out.
