Title: Preventing device for overload of hydraulic crane
Inventor: NAKAMURA SUSUMU
IPC: B66C23/90
Filed: 1980-02-16
Abstract: PURPOSE:To prevent an overload providing an unloading valve which unloads pressure oil for dangerous side operation when the held pressure of a derrick cylinder increases above a prescribed value. CONSTITUTION:If a crane is overloaded, the oil pressure of derrick cylinder 24 moves spool 4 of unloading valve A to the left via operation piping 23 of dangerous side and the oil in oil chamber 5 moves from oil chamber 6 to a tank. As a result, the pressure of oil chamber 8 decreases and poppet 7 is pushed up by the oil pressure operating on chamber 10 via piping 21. Therefore, the oil in oil passage 21 is discharged via oil chambers 10 and 11 and piping 37. Consequently, overloading of the crane is prevented.

Title: Transistor inverter
Inventor: AOIKE MINAKI
IPC: H02M7/537
Filed: 1979-02-17
Abstract: PURPOSE:To eliminate the thermal runaway of a transistor inverter by controlling a current supplied to the base of the transistor in accordance with the turn ratio of a current transformer to set to overdrive rate in special range and avoiding the unbalance of the transistor. CONSTITUTION:A pair of discharge lamps 21a, 21b are connected in parallel through a balancer 20 between the output terminals of a transistor inverter. The turn ratio of the primary windings 8a, 8b of a current transformer inserted between the primary winding of the output transformer 7 and the collector of transistors 5a, 5b and the secondary winding 8c of the current transformer is varied to control the positive feedback current supplied to the base of the transistor. The overdrive rate of the transistors 5a, 5b is set to 1.1-1.6. Even if a load becomes the state for rectifying in half wave the high frequency output at the end of the life of the discharge lamp, no unbalance occurs at the transistors 5a, 5b to prevent the thermal runaway of the inverter for stable operation.

Title: Process for preservation of seaweed gibasa in salt
Inventor: SUDOU KOUJI
IPC: A23L17/60
Filed: 1983-02-05
Abstract: PURPOSE:To enable the preservation of GIBASA (a kind of brown algae, Sargassum horneri) for a long period without deteriorating the quality, by adding salt to GIBASA immediately after harvesting from sea-water, removing the harshness, and preserving at a low temperature in a vessel having a number of perforations at the bottom. CONSTITUTION:10kg of GIBASA is mixed with about 2kg of salt immediately after harvesting from sea-water, and stirred sufficiently to contact the salt with the whole surface of the algae and prevent the exudation of viscous liquid of GIBASA. The algae is left to stand for about 1 day to remove the harshness, and preserved at a low temperature (0--10 deg.C) in a container having a number of small perforations at the bottom. In case of use, the cold-preserved salted GIBASA is taken out of the container, put into water, kneaded by hands, washed thoroughly with water 3-5 times to remove the salt, put into a proper amount of hot water of 70-80 deg.C, and stirred. When stickiness and dark green color are developed, the algae is cooled without delay by putting into water, drained, and served e.g. as the ingredient of MISO soup.

Title: Focus error control system
Inventor: ARAI SHIGERU
IPC: G11B7/09
Filed: 1985-01-31
Abstract: PURPOSE:To detect sensitively the focus dislocation by making different the photodetecting quantity of the reflecting light flux of two adjacently arranged light detecting device, amplifying the output by respective amplifiers with a different amplifying degree and setting a focus error signal to zero in he focussed condition. CONSTITUTION:Light detecting device 3 and 4 are mutually adjacently arranged with the photodetecting surface toward the reflecting light flux 1. For the arranging position, when the irradiating light flux is shifted in the radial direction in the light flux disk surface, the direction of a border line 5 is almost parallel in the shifting direction of the reflecting light flux 1 on the photodetecting surface, and arranged in the condi tion away from a border line 5 and a light shaft 9 of the light flux 1 at the prscribed distance. When such an arrangement is executed, the photodetecting quantity of the light detecting devices 3 and 4 is made different when the irradiating light flux is in the focussed condition in the optical disk surface. So that the output of amplifiers 6 and 7 to amplify the detecting output of the detecting device 3 and 4 may be equal, the amplifying degree of the amplifier 6 is made large, the amplifying degree of the amplifier 7 is made small and the output of a differential amplifier 8 is set to zero. Thus, the focus error of the irradiating light flux of the optical disk surface is easily detected.

Title: Optical transmission system of star type
Inventor: KITAYAMA TADAYOSHI
IPC: H04B10/2507
Filed: 1988-01-28
Abstract: PURPOSE:To attain signal transmission, for which the generation of a modal noise is suppressed by executing the stable coupling of a speckle pattern on the end face of a connecting part between an ascending optical fiber and a star coupler. CONSTITUTION:An interval between an input part optical fiber 5 of a star coupler 4 and a transmitting device 1 is connected by an ascending optical fiber 15 to use a single mode optical fiber. Accordingly, without generating the speckle pattern on the output end face of the acsenting optical fiber 15, since the core diameter of the single mode optical fiber, which is the ascending optical fiber 15, is smaller than that of a multimode optical fiber, the stable coupling of the speckle pattern can be executed on the end face of the connecting part between the ascending optical fiber 15 and star coupler 4. Thus, the generation of the modal noise is decreased.

Title: Constraint torque control circuit for motor
Inventor: YAGUCHI OSAMU
IPC: H02P7/288
Filed: 1991-01-18
Abstract: PURPOSE:To eliminate a variation in a constraint torque against a variation in a voltage of a power source. CONSTITUTION:A drive transistor 3 is turned ON by a start pulse of a start transistor 5 to energize a motor 2 by a power source 1. Simultaneously, if a terminal voltage of a terminal 4 is lower than a reference voltage Vref when the terminal voltage of the terminal 4 is compared with the reference voltage Vref by a comparator 8, the transistor 3 maintains a power supplying state to rotate the motor 2. If the terminal voltage is higher than the voltage Vref when the terminal voltage relative to an induced electromotive force excited at the time of rotating the motor 3 is compared with the voltage Vref during a period in which a cut-off pulse is supplied to the transistor 3 by a cut-off transistor 11, the energization is interrupted. A variation in the voltage of the power source 1 is absorbed by constant-voltage means 20 to form the voltage Vref of a predetermined voltage.

IPC: H03H15/02
Filed: 1978-02-20
Abstract: PURPOSE:To give a single frequency pass filter mechanism different in center frequency to a single-channel CTD by switching a driving frequency at a prescribed ratio. CONSTITUTION:The CTD which is constituted by sine wave and cosine wave filters F and F' having center frequencies f1 to f4 and high pass filters FH and FH' for f5 to f8 is switched at ratio f6/f5=f8/f7=1.1 by D and is driven. When the mixing wave of f2 and f7 is inptted to the filter, the signal charge proportional to the magnitude is transferred to the drain successively. When the CTD is driven at f7, only the fundamental wave of f7 passes through FH and FH', and differential- amplified phase components and amplitude components are outputted respectively and are squared in R3 and R4 rspectively and are added in K2. Then, signals corresponding to the amplitude of the fundamental wave of f2 are obtained at terminal P2. Similarly, CTD driving frequency fc is multiplied by ''1.1'' to change frequencies from f1 and f3 to f2 and f4 to obtain signals corresponding to the amplitude of the fundamental wave of f2 at terminal P1.
