Title: Zero-phase current transformer
Inventor: TOMAKI YOSHIAKI
IPC: G01R15/24
Filed: 1987-06-11
Abstract: PURPOSE:To prevent the expansion of an accident at the time of striking by lightning, by detecting each phase current of a three-phase distribution line by a photodetecting means, and transmitting its detection output to a measuring circuit by an optical fiber. CONSTITUTION:By a current flowing through three-phase distribution lines 1a-1c, a magnetic field being proportional to the current is induced in annular iron cores 2a-2c. On the other hand, emitted light beams from light emitting elements 6a-6c pass through optical fibers 8a-8c and led to magneto-optical sensors 5a-5c. As for the sensors 5a-5c, a plane of polarization rotates in proportion to a magnetic field in an air-gap of each iron core 2a-2c, and the transmission quantity of a light beam which has been made incident through the optical fibers 8a-8c is varied. The light beam which has transmitted through the sensors 5a-5c passes through optical fibers 13a-13c, made incident on light receiving elements 7a-7c in a measuring circuit 12 and converted to an electric signal, and a zero-phase current is detected. In such a way, each phase current of the three-phase distribution lines 1a-1c is detected by the magneto-optical sensors 5a-5c, and its detection output is transmitted to the measuring circuit 12 for detecting the zero-phase current by the optical fibers 8a-8c, 13a-13c, therefore, the magneto-optical sensor and the measuring circuit are separated electrically, and the expansion of an accident due to the striking by lighting can be prevented.

Filed: 1994-06-29
Abstract: PURPOSE:To provide a high-speed structured document retrieving method which can obtain a retrieval result in a practically permissible sufficient retrieval time by skipping a text included in a logical structure that is not specified as an object of retrieval and excluding it from a collating process. CONSTITUTION:In addition to the text of a document, a data base for retrieval wherein structure identifiers and their logical structure lengths are added at start positions by logical structures constituting the document is retrieved. In a forward marker decision step 40, it is decided whether or not a detected structure identifier is an identifier showing a logical structure specified as an object of retrieval once the structure identifier is detected. When the result indicates YES, an advance to a character string collation step 50 is made and retrieval is performed by the logical structure length to performs collation, thereby deciding whether or not there is a retrieved term in the character string of the text. When the result is NO, a collating process step 60 is entered, retrieval is skipped by the logical structure length, and a return to the forward marker decision step 40 is made.

Filed: 1992-05-14
Abstract: PURPOSE:To easily connect an earth retaining structure such as a panel, a pile, or a sheet pile and an anchor supporting this structure and apply no downward component force to the structure. CONSTITUTION:A drill hole 2 made deeper toward the bottom section of the natural ground 1 is excavated, and the fixing length section 5 of an anchor 3 is inserted. A hardening agent such as cement milk 6 is filled into the drill hole 2 and hardened. An earth retaining panel 7 serving as an earth retaining structure is erected at the position separated from the natural ground 1 by the preset interval. The portion of the anchor 3 protruded from the drill hole 2 is horizontally bent by 10-45 deg.. The tip of the anchor 3 is inserted into the head 9 of the notch portion 8 of the panel 7 and fixed. The portion of the anchor 3 connected to the panel 7 is horizontal, thus no labor is required to machine the panel 7 in response to the inclination angle of the anchor 3. The downward component force by the tensile force of the anchor 3 is dispersed to the ground directly below the bent portion, and it is not applied to the portion directly below the structure.

Title: Vibration isolating rubber part for vehicle
Inventor: FUJIWARA KATSUYOSHI
IPC: B32B5/12
Filed: 1990-06-05
Abstract: PURPOSE:To enhance the adhesion to a metal by compounding short fiber, having elastic modulus of specific value or more, by a specific amount in one direction with matrix rubber, having specific elastic modulus, and generating elastic modulus different in two orthogonal directions. CONSTITUTION:For instance, a vibro-isolating rubber 25 is mounted to an end part of a trailing arm 24 of a front suspension and connected to a car body frame member 26. The vibro-isolating rubber 25 is constituted of an annular short fiber reinforced rubber simple substance by compounding a short fiber, having 800kg/mm<2> or more elastic modulus as a reinforcing short fiber, by 1 to 50volume% dispersed parallelly to an axial line L with matrix rubber having 1X10<7> to 2X10<8>dyn/cm<2> elastic modulus. In the vibro-isolating rubber 25, the elastic modulus is large in a fiber orientation direction and small in an orthogonal direction. Accordingly, adhesive force to a metal is increased by substantially decreasing a fiber amount in the case of obtaining elastic modulus equal to as in the past in the fiber orientation direction.

Title: Indicating device of gas water heater
Inventor: OONISHI NOBUO
IPC: F24H1/10
Filed: 1983-08-12
Abstract: PURPOSE:To improve the operational convenience by a method wherein the number of lit indicator lights is changed in response to the hot water delivery capacity in a gas water heater, which is equipped with a proportioning valve, a temperature sensing element and a plurality of indicator lights and the hot water delivery capacity of which is made continuously variable. CONSTITUTION:When a water heater is put into actuation, a large current flows in a proportioning valve 4, resulting in producing a high voltage across a resistor 7. Because an operational amplifier 18 acts as a voltage follower, its input voltage is outputted as it is, resulting in producing a high voltage across a resistor 8. Because operational amplifiers 19-22 act as voltage comparators and yet the output voltage of the operational amplifier 18 is higher as compared with the non-inverted input voltages of the operational amplifiers 19-22, the outputs of the operational amplifiers 19-22 are low, resulting in flowing current in LED's 23-26, which are respectively connected to the operational amplifiers 19-22, and consequently brightening LED's. On the other hand, when a small current flows in the proportioning valve 4 or the water heater burns on a small capacity, several LED's are lit, resulting in enabling indicate the capacity of the water heater.
