Title: Preventing method for edge crack in rolling work for steel
Inventor: KOIKE MASAO
IPC: B21B3/00
Filed: 1979-08-08
Abstract: PURPOSE: To perfectly prevent the intergranular oxidization, and to prevent the generation of the titled edge crack, by combining the application of the oxidation inhibitor to the billet surface and the covering for the billet surface with the steel sheet.  
     CONSTITUTION: The oxidation inhibitor is applied to the surface of the billet of the high alloy steel, especially the high Ni alloy, etc., of readily oxidized at the heating period. A part or whole of the billet surface is covered with the steel sheet and the billet is heated; hereby, even if the applied oxidation inhibitor is placed under the molten state at the high temperature region, the dropout of the molten inhibitor is prevented by the steel sheet covering. As a result, the intergranular oxidization can be perfectly prevented. Besides, if the intergranular oxidization resistance of the billet itself is improved by containing ≤0.1% amount of one kind or more of Ca, Mg, Y, and rare earth elements in the steel, the oxidization preventing effect is improved.

Title: Currency discriminator
Inventor: SONOBE MAMORU
IPC: G07D7/00
Filed: 1995-04-25
Abstract: PURPOSE: To register the reference values for coin discrimination independently of one another by automatically discriminating coins different by denominations by a device at the time of registering the reference values used for coin discrimination. CONSTITUTION: At the time of coin discriminating operation, detection data corresponding to the shape and materials of a coin 2 passing in a coin passage 6 is obtained from a first sensor 4 and a second sensor 5, and this detection data is compared with reference values for discrimination held in a memory to discriminate whether the coin is true or not. At the time of reference value register operation, plural coins for reference value acquisition are thrown from a coin slot 3; and if detection data outputted from sensors 4 and 5 at this time doesn't coincide with any temporary reference values temporarily registered in the memory, this detection data is temporarily registered in the memory as another temporary reference value.  If detection data outputted from sensors coincide with a registered temporary reference value, this detection data is used to correct and rewrite this temporary reference value. At the time of the end of register operation, temporary reference values are set as new reference values for discrimination.

Title: Movable impeller turbine
Inventor: HAYAKAWA KEIZOU
IPC: F03B3/14
Filed: 1981-07-01
Abstract: PURPOSE:To reduce the size of a runner servo-motor by mixing the molybdenum disulfide into the lubrication member placed in the runner boss thereby reducing the frictional force. CONSTITUTION:The runner impeller 1 fixed to the runner boss is operated by supplying the oil in the pressure oil tank 4 to the runner servo-motor 3 by means of a pump 5 through the link mechanism or a runner impeller spindle bearing 2 arranged in the runner boss. The power required for the servo-motor is the hydraulic moment to be applied on the runner impeller and the frictional force of the runner impeller open/close mechanism where said frictional force is reduced by reducing the friction factor. When mixing the molybdenum disulfide of 5-10% into the lubrication oil to be contained around the link mechanism or the spindle bearing 2, the friction factor is reduced thus to reduce the power required for the motor 3. When it will exceed over 10%, the frictional force will not drop thereby 5-10% is economical.

Abstract: PURPOSE:To avoid production of a defective product and to automate an operation further by a method wherein a resin-sealed state of a semiconductor device is inspected and a dripping condition of a resin is controlled on the basis of this inspection result. CONSTITUTION:A film-carrier semiconductor device which has been pulled out from a supply-side reel 13 is inspected by using a photosensor 20 in order to confirm that a semiconductor chip has been mounted on a prescribed position. When the semiconductor chip has been mounted on the prescribed position, a resin is dripped when the semiconductor chip is conveyed under a syringe 18. An amount of the resin to be dripped is controlled by using a dispenser 15; the resin of a preset amount is dripped on the semiconductor chip from the tip of a needle 19. Then, a spreading property of the resin on the semiconductor chip immediately before the chip is conveyed into a baking furnace 16 is inspected by using a TV camera 22 for inspection use. This inspection result is sent to a control part and is compared with an optimum state which has been set in advance in the control part. The control part changes a dripping condition of the resin. Thereby, a production yield in a resin sealing process is enhanced, and high quality can be maintained.

Abstract: PURPOSE:To execute easily the accurate positioning between fiber and light guide and to improve the yield by making the interval of the fiber.guide wide at the near side of the light guide edge part and making the interval narrow taper-shaped at the far side. CONSTITUTION:The interval of a fiber.guide 4 is wide at the near side and narrow taper-shaped at the opposite side. When the fiber is inserted into the guide, a fiber outer diameter D1 is larger than a guide interval W2, therefore, the fiber is mounted on the guide. The position of the core center of the fiber is on a central line 00'. At such a time, the fiber is accommodated into the guide. The core center still mounted on a central line 00'. When a guide width W1 is wider than a fiber outer diameter D1, the positioning action in the transverse direction does not exist at the area. Since the center of the fiber core is mounted on the central line 00', the fiber center is mounted the central line 00'. Consequently, a fiber core 1a and a light guide core 3 are positioned.

Title: Picture display device
Inventor: UEDA MINORU
IPC: G09G1/20
Filed: 1984-05-21
Abstract: PURPOSE:To display a video image with high accuracy close to a picture at interlacing by superimposing a square wave signal having a frequency obtaind by a multiplying a vertical deflection frequency by a horizontal deflection signal at the reception of the said signal at the reception of a non-interlace synchronizing signal to attain vertical deflection. CONSTITUTION:The square wave signal repeating ''H'', ''L'' at each H/6 period in each horizontal period is superimposed on a conventional vertical deflection signal and the vertical deflection signal whose amplitude changes in two stages at each H/6 period is used to apply the vertical deflection. Since the electron beam is driven vertically during one horizontal period to change over the beam irradiation time, although the luminance level is decreased, the information is unchanged in case of a binary signal, then the double density effect of scanning lines is realized by using the vertical deflection signal shown in Fig. (b). The vertical deflection signal above is generated by a circuit shown in Fig. (a). That is, a voltage value at each stage of the vertical deflection signal is stored in a memory 27 and a D/A converter 39 converts the signal read out of the memory 27 into an analog voltage shown in Fig. (b). In such a case, the address of read of the memory 27 is designated by using a pulse signal 6H having a frequency 6 times the horizontal synchronizing signal H in addition to outputs A0-A7 of the vertical deflection counter.

Filed: 1984-05-21
Abstract: PURPOSE:To improve the communication efficiency of a network system and the system reliability by allowing a transmitter (node) participating newly in the network to recognize all nodes in the network without needing a special monitor node at the same time. CONSTITUTION:When a power supply is applied to a node c4 and the participation in the network is attained, the node c4 acquires the communication right by a token from a node d5 and transmits a transmission frame such as a token to other node. The node d5 detects it, the node c4 participates newly in the network, and since a node address ''3'' of the node c4 is effective, the destination address node (b) in a RAM16 is rewritten from ''2'' to ''3''. When the own node destination token is received from a node e6, a new participation notice instruction (SNN instruction) to all nodes in the network is written in the address of the node participated newly in a data area 44 and transmitted. Each node uses the received SNN instruction to recognize that the new node c4 is participated in the network.
