Title: Flatness measuring apparatus
Inventor: OGAWA HIROSHI
IPC: G01B11/30
Filed: 1986-09-30
Abstract: PURPOSE:To suppress a measuring error due to vibration to a min. extent, by moving a distance measuring sensor without moving a body to be measured. CONSTITUTION:Since a rail 40 is layed on a measuring stand 24 having a body 47 to be measured in parallel not only to the upper surface of said stand 24 but also to the measuring direction of the body 47 to be measured, when a measuring arm 32 is moved by a moving mechanism, the distance measuring sensor 36 mounted on the measuring arm 32 moves in the measuring direction at the position above the body 47 to be measured. In this case, when the distance measuring sensor 36 is mounted to the measuring arm 32 at the central position thereof in the moving direction, even if pitching vibration caused by the movement of the measuring arm 32 is generated, the positional change of the distance measuring sensor 36 hardly generates and, therefore, a measuring error due to vibration is reduced.

Title: Diagnosis of hot-line deterioration for overhead transmission line
Inventor: SANO YOSHIRO
IPC: G01N27/26
Filed: 1987-09-14
Abstract: PURPOSE:To enable diagnosis of deterioration of an overhead transmission line under a hot-line state, by measuring the concn. of metal ions composing a steel core existing in a water drop falling through the inside of the overhead transmission line. CONSTITUTION:A steel core 1 in a steel core aluminum twisted wire used as overhead transmission line generally employs a Zn plated steel wire. As Zn composing a Zn plated layer is lower in the electrode potential at a potential difference train than Fe composing the steel wire and Al composing an aluminum strand 2, it is initially corroded with the presence of an electrolyte. Thus, after a rainfall, a water drop falling from an electric wire is recovered to perform a chemical analysis of the concn. of Zn ions in the water drop thereby enabling accurate diagnosis of the degree of deterioration in the wire. This eliminates the need for interrupting the transmission line in the recovery of the water drop thereby permitting diagnosis of deterioration at any time under a hot line state.

Abstract: PURPOSE:To reduce the discharge amount of hydrocarbon at the time of the low load of an engine and the temperature of exhaust at the time of the high load, by re-burning an unburnt constituent in exhaust gas through the utilization of a connecting passage at the time of the low load, and meanwhile, reducing the resistance of exhaust through the utilization of the ventilating passage at the time of the high load. CONSTITUTION:Connection between a connecting passage 14 and an exhaust gas leading out passage 15 is cut off by closing a control valve 16 at the time of the low load of an engine, and when the secondary exhaust port 13a of one cylinder, for example, the 1st cylinder 1a, opens within a combustion chamber, unburnt exhaust gas is delivered under pressure through the connecting passage 14 to the combustion chamber of the other cylinder, for example, the 2nd cylinder 1b. And burnt gas is discharged into an exhaust passage 9 from the primary exhaust port 12 of the 2nd cylinder 1b. Meantime, connection is made between the connecting passage 14 and the exhaust gas leading out passage 15 by opening the control valve 16 at the time of the high load of the engine, and exhaust gas is discharged through both of the primary exhaust ports 12a, 12 and secondary exhaust ports 13a, 13.

Title: Program transfer control system for terminal equipment
Inventor: FUKASAKU KAZUHIKO
IPC: G06F12/00
Filed: 1990-09-03
Abstract: PURPOSE:To safely and accurately select and execute the operation programs by discriminating the program file information from the normal on-line work information and dividing the file information into proper sizes to transfer them in parallel with each other. CONSTITUTION:A master station 10 sends intermittently or continuously the program file control information 12 and the divided program files 13 to a slave station 20 in the form of transfer programs based on the terminal control information 11. In this case, a communication circuit or a time band where the coefficient of utilization of LAN is kept low is selected for transfer of programs. Otherwise the programs are periodically transferred within such a range of the circuit using rate that exerts less influence on the on-line work. Thus the station 10 (CPU) can surely control the program of the station 20 (terminal equipment).

Title: Capillary electrophoresis device
Inventor: ARAI AKIHIRO
IPC: G01N37/00
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To provide a capillary electrophoresis device which can automatically make optical axis alignment. SOLUTION: A movable stage 3 is moved so that a laser beam can traverse an electrophoresis groove 2 on an electrophoresis chip 1. Since the laser beam has a diameter of about 10m and the groove 2 has a width of 30m and an inverted trapezoidal cross section, the scattered light of the laser beam becomes the maximum when the laser beam hits the side face of the groove 2 and minimum when the laser beam hits the central part. The scattered light reaches a photomultiplier 11 through an interference filter 9. A CPU 14 stores the position (of the stage 3) at which the first peak is detected by moving the stage 3 and the position (of the stage 3) at which the second peak is detected by further moving the stage 3. Then the CPU 14 returns the stage 3 so that the laser beam can be positioned to the middle of the two positions by sending a drive signal to a pulse motor driving circuit 15.

Filed: 1998-08-17
Abstract: PROBLEM TO BE SOLVED: To complete a semiconductor thin film as well as suppress the rise in temperature in a gallium arsenic device, by providing a semiconductor element formed on the semiconductor thin film and a diamond substrate onto which the semiconductor thin film is adhered. SOLUTION: This device is provided with a field effect transistor 107 formed on a diamond substrate 105 as well as an n-type GaAs working layer 103 as a channel layer where electrons run on an undoped GaAs layer 104. Further, it is provided with a source electrode 101a, a drain electrode 101b and a gate electrode 102. The diamond substrate 105 requires a thickness of 25-50 μm enough to hold the field effect transistor 107 by itself only. If a high-frequency integrated circuit including the field effect transistor is formed instead of a GaAs substrate on the diamond substrate, an impedance line same as that on the GaAs substrate is formed. Thus, the diamond substrate 105 having a high thermal conductivity is used instead of the GaAs substrate, so that the thermal resistance of a GaAs semiconductor device can be reduced and an integrated circuit to cope with high frequency be formed.

Title: Biaxially oriented thermoplastic resin film
Inventor: ABE KOICHI
IPC: B29C55/02
Filed: 1988-09-14
Abstract: PURPOSE:To contrive to enhance the scratch resistance of film by a structure wherein a layer, which consists of composition having main component of thermotropic liquid crystal polymer and has the predetermined thickness, is laminated onto at least one side of thermoplastic resin layer. CONSTITUTION:The film concerned is produced by laminating thermotropic liquid crystal polymer onto at least one side of biaxially oriented thermoplastic resin layer. The necessary thickness of the thermotropic liquid crystal layer of the film is 0.01-5mum. The thickness of the thermotropic liquid crystal polymer layer, which lies out of said range, is not favorable, since the resultant film shows poor scratch resistance. Thus, since the flexibility of, thermoplastic resin and the stiffness and strength of thermotropic liquid crystal polymer can be utilized to their maxima, the scratch resistance of the film can be enhanced.
