Title: Water floater
Inventor: YOSHIKAWA YOSHIAKI
IPC: B63B35/76
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To provide a water floater capable of filling and discharging air to a floater body in a short time, having high safety, low cost and good convenience in use. SOLUTION: This water floater 1 is provided with opening parts through which an angler stretches his legs. A valve 9 for filling or discharging air to an inside floater body 2a is installed on a floater body 2, and the floater body 2 is formed of a rubber martial such as butyl rubber. Since a butyl rubber material as a rubber material having high durability is sued for a raw material of the floater body 2, air is not blown up all at once even if a pin hole is generated caused by a fish hook, and therefore, high safety can be achieved, and reduction of cost can be also achieved.

Title: System for measuring laid depth of submarine conductor
Inventor: MIURA TOKUNORI
IPC: G01V3/11
Filed: 1983-04-01
Abstract: PURPOSE:To make it possible to simply measure laid depth by eliminating the influence of earth and sand on the sea bottom, by generating a magnetic field by flowing an AC current through a submarine laid conductor while detecting the direction of said magnetic field by a plurality of magnetic field direction detectors. CONSTITUTION:When an AC current is flowed through a submarine laid conductor 1, an AC magnetic field H is generated and the direction thereof comes to a right angle to the line connecting the conductor 1 and a point O. When the directions of the magnetic field, that is, the angles beta1, beta2 at two points P1, P2 spaced apart a distance x0 to each other are measured, a laid depth r0 can be calculated from a predetermined calculation formula. In an actual apparatus, two magnetic field direction detectors each constituted of magnetic sensor are attached onto a moving stand 3 and drawn by a measuring ship 6 to traverse above the conductor 1. The directions of the magnetic field detected by two detectors 5 are inputted to a signal treating apparatus to measure the laid depth of said conductor 1. By this mechanism, because the angle of the magnetic field is not attenuated by earth and sand, the laid depth can be simply measured without receiving the influence of earth and sand.

Title: Photoconductive thin-film for television camera tube using photosensitizer layer containing amorphous silicon
Inventor: INOUE HIDEKAZU
IPC: H01L31/08
Filed: 1980-04-30
Abstract: PURPOSE: To decrease dark currents and obtain a photoconductive thin-film having high sensitivity by forming the photoconductive thin-film consisting of layer structure, such as a blocking layer using amorphous Si as a material and a photosensitive layer on a conductive supporter.  
     CONSTITUTION: A blocking layer being composed of an amorphous Si semiconductor is grown on a conductive transparent electrode of a conductive supporter. The blocking layer prevents the injection of charges to a photosensitive layer being formed in the following process, and lowers the rate of apparent dark currents without inhibiting photoconductivity. An amorphous semiconductor photosensitive layer into which P or B is doped is laminated, and a photosensitive layer is built. The photoconductive gains of the photosensitive layer are increased by means of the doping of P, but dark currents are also augmented at the same time. Thus, dopings of no P and B, small amount of P or B, etc. are adequate. A cover layer improving charge holding capability in case of scanning by electron beams is formed on a film with double structure prepared according to the above-mentioned process.

Title: Optical modulator
Inventor: MIYAZAKI CHUICHI
IPC: G02F1/03
Filed: 1989-03-13
Abstract: PURPOSE:To obtain an electro-optical crystal of high sensitivity by cutting thinly the electro-optical crystal in the voltage applied axial direction, reversing alternately the axial directions, and also, forming a lamination type structure in which the positive and the negative electrodes are placed alternately. CONSTITUTION:The dimension of the voltage applied direction of electro-optical crystals 2 - 5 is demarcated and divided equally, arranged so that the directions of intrinsic axes which the crystal in the voltage applied direction has are all opposed to each other, and also, electrodes 6 - 10 are placed so that each crystal 2 - 5 is inserted and held, and also, the polarity becomes alternate and these are allowed to adhere closely to each other. In this case, in the crystal, a uniform and strong electric field is generated, and for instance, when a laser beam 11 is allowed to pass through, the laser beam 11 is split and advances in all the crystals, but since it is subjected to a phase modulation of all the same quantity, the light beam which passes through these crystals 2 - 5 is regarded just like one light beam which passes through a uniform crystal. In this case, however, the electric field strength of split number folds of the crystal is obtained. In such a way, an electro-optical crystal of high sensitivity can be obtained.

Title: Reproducing device of recording medium
Inventor: ODAKA SHIYUUICHI
IPC: G11B27/10
Filed: 1982-04-07
Abstract: PURPOSE:To obtain a recording medium reproducing device which detects easily the start position of a desired recording signal, by constituting the device so that an inter-music gap position other than an objective inter-music gap position is displayed as a numeric value on a tape counter till the next inter-music gap position is detected even when the inter-music gap position other than the objective inter-music gap position is detected. CONSTITUTION:When a tape 2 is reproduced, a signal indicating a numeric value corresponding to a position on the tape 2 is detected continuously by a tape position detecting part 5 and is applied to a signal holding part 13, and it is determined by the signal from a tape boundary discriminating part 10 whether the signal of the signal holding part 13 should be outputted to a display part 15 or not. When an inter-music gap signal which releases the latch state of a latch circuit 14 is applied, the signal at this instant is outputted to the display part 15. Since the numeric value indicating the position of the preceding inter-music gap signal (inter-music gap position) is displayed fixedly until the next inter- music signal is discriminated, the current running position and the current music position of the tape 2 are discriminated on a basis of this numeric value.

Title: Solar air conditioner
Inventor: INOUE HISAMICHI
IPC: F24F11/02
Filed: 1993-03-18
Abstract: PURPOSE:To alleviate a power source change of a commercial power source system due to a variation in a solar radiation by so controlling a load current of an electric load apparatus as to always hold an output voltage of a solar energy electric converter at an optimum operating voltage. CONSTITUTION:A reference voltage generator 7 generates an optimum operating voltage of a solar cell, sends it to a potential difference converter 8, obtains a difference from an outlet side voltage of a double voltage rectifier 4, and sends its difference signal to an ON/OFF deciding unit 9. The unit 9 sends, if the signal is positive (the reference voltage is high), a contact signal of an ON state to an inverter load controller 11 through a load current limiter 10, and lowers an inverter load. The limiter 10 monitors the load current, maintains the OFF state in the case of a lowest load current, and eliminates transmission of a control signal to the controller 11. Accordingly, an air conditioner is not stopped. That is, a variation in a commercial system power source is suppressed, and commercial AC power is deleted, thereby obtaining an energy conservation effect.
