Title: Scott connection transformer
Inventor: ASAKURA MASAKATSU
IPC: H01F30/14
Filed: 1984-01-30
Abstract: PURPOSE:To enable taking out each two two-phase alternating currents which are 90 deg. different in phase by providing independent two secondary windings each of a main transformer and a teaser transformer. CONSTITUTION:The ends U, V and W of primary windings 111-122 and 311- 322 are connected to each phase of a three-phase power source and a single- phase alternating current appears at the both ends y1-y2 of the secondary windings 21, 22 and both the ends y3-y4 of the secondary windings 201, 202 of a main transformer respectively. Both the single-phase ACs are the same phase. A single-phase AC also appears at both the ends x1-x2 of the secondary windings 41, 42 and both the ends x3-x4 of the secondary windings 401, 402 of a teaser transformer respectively. Both the single-phase ACs are the same phase but have phase difference of 90 deg. from the single-phase ACs taken out from the main transformer. Thus, the same phase two single-phase ACs from the main transformer and two single-phase ACs which have phase difference of 90 deg. from the former ACs from the teaser transformer can be taken out.

Title: Optical communication system
Inventor: TATSUTA MITSUHIRO
IPC: H04B10/00
Filed: 1981-02-06
Abstract: PURPOSE:To easily execute the axial matching of an optical fiber, and also to raise the transmission characteristic, by varying in order the diameter of a core, the number of openings and the refractive index distribution factor of the optical fiber constituting an optical transmission line ranging a receiving terminal from a transmitting terminal. CONSTITUTION:An optical transmitter A having a light emission element and an optical receiver B having a photodetecting element are connected by an optical line L. The optical line L is formed by mutually connecting partitioned lines l1-l5. The diameter of a core, the number of openings and the refractive index distribution factor of each partitioned line are made minimum at the center line l3, and are made larger in order of its outside lines l2, l4 and subsequently l1, l5. In this way, as for the line whose core diameter is small and the line whose core diameter is large, the axial matching is executed easily, and the accuracy of a connector is alleviated. Furthermore, said line is connected with an optical fiber whose number of openings is large, with a small connection loss, the attenuation characteristic of an optical signal is improved by setting a refractive index distribution factor, and high optical power is secured.

Title: Display device for intra-finder information
Inventor: NAKAYAMA HIROKI
IPC: G03B17/20
Filed: 1987-01-26
Abstract: PURPOSE:To attain excellent observation by means of a simple constitution by engraving intra-finder information in the vicinity of a position on which an image of an object is to be formed and observing the information together with the real object image. CONSTITUTION:The object image formed by an object lens 1 is observed by an eyepiece 4 as an erect normal image through a field lens and a porro prism 3. A field frame 11 in finder observation, a focusing frame 12, a correcting frame 13 for a finder field frame for a close range object, and character information 14 are engraved as V-grooves on an optional face of the porro prism. Since the intra-finder information is directly engraved on the porro prism, a process for evaporation or the like is unnecessary, the constitution is simplified, the generation of ghosts is prevented, and excellent observation can be attained.

Title: Fuel-supply control device
Inventor: NAGAOKA YUKIO
IPC: F23N1/08
Filed: 1979-02-14
Abstract: PURPOSE: To obtain a device of high safety and with large practical effect in which a fluid to be heated can be used with low flow rate and boiling is not produced when the temperaure is set high, while it can be used even with large flow rate when the temperature is set low.  
     CONSTITUTION: When a regulating valve 12 is fully opened, the whole water flows into a venturi pipe 10, producing a large differential pressure in the venturi pipe 10 with comparatively low quantity of water, thereby high temperature of water being obtained. As the regulating valve 12 is opened, the water flows also into the side of a bypass 11 and the differential pressure produced in relation to the whole quantity of water becomes smaller than that in the case of full closure of the regulating valve 12, thereby the low temperature of water being obtained. Since the differential pressure in the venturi pipe 10 acts also on a diaphragm 14 of a hydraulic responsive-motion valve 19, a gas valve 18 is to be open with low quantity of water by closing the regulating valve 12. Moreover, though the venturi pipe 10 has a considerably large pressure loss, it is reduced by letting water flow also to the side of the bypass 11. In addition, the regulating valve 12 is controlled by a step part 2b, thereby the boiling can be prevented.

Title: Picture reading device
Inventor: MATSUDA SHINJI
IPC: G06K9/20
Filed: 1985-01-31
Abstract: PURPOSE:To read and process surely an optionally designated partial picture in a specified picture area of a form by detecting an assigned frame utilizing level difference of picture signals between characters and the assigned frame in the picture area of the form. CONSTITUTION:A photoelectric converting section 1 converts characters and the assigned frame recorded on a form to electric signals and outputs digital signals to the first and second comparators 4, 5 through an amplifier and an A/D converting section 3. In such a case, the assigned frame on the form and characters in it are scanned in the converting section 1. Out of signals obtained through the amplifier 2, etc., signals corresponding to the assigned frame become lower in level than signals corresponding to characters in the picture area. Accordingly, the assigned frame can be detected by utilizing the level difference of picture signals between characters and assigned frame in the picture area of the form. Further, picture data of characters in the assigned frame can be deleted from the picture area, or picture data other than the assigned area can be deleted. That is, and optionally designated partial picture can be read and processed surely by only writing the assigned frame on the form.
