Title: Measurement of position on the ground by geostationary satellite
Inventor: KAWASE SEIICHIRO
IPC: G01S3/14
Filed: 1986-03-31
Abstract: PURPOSE:To enable the position of a radio wave transmitting point to be specified without being accompanied by he uncertainty of meridional symmetry or equatorial difficulties by restoring temporal changes in the received phase difference between both antennas on both ends of a rod to sinusoidal changes and specifying the position of the radio wave transmitting point on the basis of the amplitudes and the phases of the sinusoidal changes. CONSTITUTION:The amplitude (a2) of a curve corresponding to a point 2 is equal to the sine of the angle between straight lines 4-5 and 2-5 and an amplitude (a3) is equal to the sine of the angle between the straight lines 4-5 and 3-5. If the position of a satellite 5 is known, since the positions of the points 2 and 3 are known and the amplitudes (a2) and (a3) are obtained from measurement, the position of a point 4 can be obtained. The amplitude (a1) is equal to the sine of the angle between the straight lines 4-5 and 1-5. When a value 2pi tT (T: rotational period of rod) is obtained from the phase difference (t) between the curves 31 and 32, this value is equal to the angle between the straight lines 1-4 and 2-4 as viewed from the satellite. Since the position of the point 4 has been obtained as described above and the amplitude (a1) and a time (t) are obtained from measurement, the position of a point 1 can be obtained.

Title: Polarity tester of transformer
Inventor: KITAGAWA HIDEO
IPC: G01R31/06
Filed: 1986-03-31
Abstract: PURPOSE:To enable simple and dependable polarity measurement, by giving a square wave to the primary side of a specimen transformer, and detecting only a signal of a single-pole characteristic generated in synchronization with one of the levels of the square waves among voltage signals induced on the secondary side. CONSTITUTION:An oscillator OSC generates a square-wave voltage signal VOSC of a constant frequency. By operation of a switch by this, the primary current I1 of a square-wave shape is allowed to flow into a transformer T from a voltage source E. By this action, a peak-pulse-shaped voltage signal V2 of each different polarity is induced on the secondary side of the transformer T of rise-up and breaking time. Consequently, when a signal of, for example, positive polarity is detected in synchronization with one level of the primary side square- wave, for instance, a higher level, in the case of the depolarization, above pulse signal is detected at every rise-up time of the square-wave, however, in the case of the additive polarity, it is not detected at all.

Abstract: PURPOSE: To make the control of the amount of abrasive materials adequate by hermetically sealing the one comprising dispersing abrasive materials in a solvent and letting the solution be impregnated in a fabric-form member by foil-form packaging material.  
     CONSTITUTION: It is advantageous to use nonwoven fabrics as the fabric-shaped member because there is no danger of damaging the photosensitive layer.

Title: Reflection type photoelectric switch
Inventor: FUKUYAMA TOSHIBUMI
IPC: G01S17/04
Filed: 1978-06-19
Abstract: PURPOSE: To enable only the required object to be detected by so constituting the switch that its detection region is narrowed and that the detection distance from the photoelectric switch up to this detection region may be continuously changed.  
     CONSTITUTION: When a knob 47 is operated, a projecting part holder 21 and photo detecting part holder 31 both rotate at the same angle and therefore the crossing position of the projecting flux 26 and photo detecting flux 36 moves on the central axis 18 of a photoelectric switch 1. Hence, if the detection distance l is adjusted by turning and operating this knob 47, only the detection object 71 may be detected even if the intended detecting object 71 and unnecessary object 72 exist in considerable proximity. At the time of adjusting said detection distance l, the aim 17 provided on the outside surface of the case 10 of the photoelectric switch 1 indicates the central axis 18 and therefore fairly accurate operation may be accomplished through visual observation based on this aim 17.

Abstract: PURPOSE:To improve the moldability of resin coated sand and the casting mold strength at elevated temp. in an unsatd. polyester resin compsn. for binding of sand by using hydrogenated bisphenol A for a polyhydric alcohol component and adding a specific metallic oxide thereto. CONSTITUTION:A titled compsn. contains an unsatd. polyester of >=50 deg.C softening point measured by a ring and ball method which is prepared by reacting alpha,beta- unsatd. dibasic acid and an acid component including satd. dibasic acid as required, with a polyhydric alcohol component in which 10-100mol% of polyhydric alcohol is hydrogenated bisphenol A, an unsatd. monomer or prepolymer having >= one polymerizable double bond in a molecule, a polymerization catalyst and an oxide of a metal of the group I -IV or VIII. The softening point of the unsatd. polyester resin obtd. by the above-mentioned method is high and the heat resistance is improved. Since the melt sticking point is improved by the addition of the above-described metallic oxide without increasing the softening point considerably, the purpose is achieved.
