Title: Automatic windshield wiper with rainfall sensor
Inventor: NIKUDO YOSHIJI
IPC: B60S1/08
Filed: 1980-07-14
Abstract: PURPOSE: To sense rainfall and actuate automatically a windshield wiper by leading the light into the glass through a prism fixed to the glass, and by receiving change of the light, reflected internally at the boundary of the glass and the air, with a photoreceiving element through the prism.  
     CONSTITUTION: The light from a source 1 is led in the glass 5 through a lens 2, a light fiber 3, a prsim 4 fixed to the surface of the glass 5, and reflected intenally at the boundary 6 of the air and glass 5, and then led to a photoreceiving element 8 through the prism 4 and light fiber 7. When the glass 5 is coated with rainwater 11, part of the light is deviated away as shown by the arrow because the refractive index from glass to rainwater is smaller than that from glass to air. Thereby, the light which reaches the photoreceiving element 8 is decreased and the electric signal which reaches the electric circuit 9 is accordingly changed, and thus the windshield wiper 10 will come into operation.

Title: Facing stabilizing method of muddy water type shield construction method
Inventor: ARIMA MORIO
IPC: E21D9/06
Filed: 1995-03-29
Abstract: PURPOSE: To quickly deal with facing control, reduce muddy water controlling facilities and a stock quantity of muddy water for countermeasure of mud release so as to reduce land area for ground facilities, and save the area. CONSTITUTION: When muddy water is fed in the shield chamber 42 of a shield machine 34 so as to stabilize a facing 46 by muddy water pressure, a thickener tank 50, a filling material tank 52, and a viscosity meter 60 are arranged on the way of a mud feed pipe 44 in a tunnel 36 in rear of the shield machine 34. The thickener and the filling material are fed in the mud feed pipe 44 from the thickener tank 50 and the filling material tank 52, while detecting viscosity in the mud feed pipe 44 by the viscosity meter 60, based on facing data detecting the condition of the facing 46. Hereby, mud feed distance of adjusted mud water to the facing can be shortened, and quick correspondence against change of stability of the facing can be performed.  Because muddy water is controlled in the tunnel 36 in the vicinity of the shield machine 34, muddy water controlling facilities on the ground or in a starting shaft become unnecessary, and the area of the ground facilities can be saved.

Abstract: PURPOSE:To detect the signal level up to the area of the stronger level of reception input by providing the level addition circuit which adds respective detection outputs of a first level detection circuit and a second multi-stage level detection circuit. CONSTITUTION:At the time or reception input or a strong never, the base voltage of a transistor TR Q12 for signal input of a differential amplifier 111 in the first stage is raised, and thereby, the voltage between the collector and the emitter of this TR Q12 approaches 0V to enter into the saturation operation area, and then, a PN junction diode between the base and the collector of the TR Q12 is turned on to clamp the base voltage.

Abstract: PURPOSE:To provide a compsn. giving a transparent film which is freed from the problems of brittleness and becoming sticky by moisture absorption, containing gelatin and a water-soluble or water-dispersible block copolymer composed of a PVA polymer and an ionic group-contg. polymer. CONSTITUTION:The titled compsn. contains gelatin and a water-soluble or water- dispersible block copolymer comprising a PVA polymer as one component and an ionic group-contg. polymer as the other component (e.g. a polymer obtd. by radical-polymerizing a radical-polymerizable ionic group-contg. monomer in the presence of a PVA polymer contg. a mercapto group at its terminal obtd. by saponifying a polyvinyl ester polymer contg. a thiol ester group at its terminal). Since gelatin has poor compatibility with PVA polymers, it was impossible to use gelatin as a mixture with the PVA polymers. However, by using said block copolymer, gelatin can be mixed with the polymer with good compatibility to afford a film which has good transparency and a high strength and does not become sticky by moisture absorption.

Title: Detector for travel route of traveling object
Inventor: KUMAGAI TATSUYA
IPC: G05D1/02
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To provide an autonomously traveling detector for traveling route of traveling object low in cost and easy to be used by receiving position information, detecting the rotary angle and the travel distance of a traveling object and obtaining a traveling route from position information, the rotary angle and the travel distance. SOLUTION: While a carriage 1 travels, an optical fiber gyro 4 detects the rotary angle of the carriage 1 and a rotary encoder 5 detects the travel distance of the carriage 1. The rotary angle and the travel distance are sampled at prescribed time intervals during a period when measurement is required and position information which a position information receiver 3 receives is taken in. In an interface board 8, a relative position by the shift of the carriage 1 within the time interval is obtained by an operation by the rotary angle detected by the optical fiber gyro 4 and the travel distance detected by the rotary encoder 5. Then, the travel route of the carriage 1, which is obtained by measurement, is expressed. Thus, an inexpensive sensor and inexpensive map data can be used.

Abstract: PURPOSE:To secure an automatic selection for the communication carried out via the tandem office or the communication carried directly between stations by selecting the better one of the two wave paths after the S/N comparison, thus always maintaining the circuit of the better side. CONSTITUTION:For the start of communication between communication stations 9 and 10, signal generator 16 repeats the make and break in case the communication is given to station 10 from 9, and signal detector 17 detects the make and break within tandem office 11 to emit intermittently the wave of frequency B.

And in case frequency B is decided better, generator 16 is actuated continuously to secure the operation of repeater 11 at all times. In the contrary case, the direct reception is given with no intervention of repeater 11. Thus the wave featuring the better S/N is selected automatically thereafter.
