Abstract: In a casting method comprising casting a slip containing water or an organic solvent as the medium into a mold and removing the mold after solidification of the slip, use of a mold formed with an organic binder soluble in the medium of the slip allows the slip to quickly solidify and afford a green body due to absorption of the medium in the slip by the mold. In this case, the mold softens with loss of the binding power thereof simultaneously with the absorption of the medium. Therefore, no cracks appear at all in the green body, and removal of the mold is very easy.

Abstract: A shift indicator system for a vehicle comprises an engine speed sensor, an engine speed comparator for comparing the engine speed detected by the engine speed sensor with a preset value, an indicator which provides an indication for directing upshifting when the engine speed is not lower than the preset value, a delay circuit which inhibits the indicator from providing the indication for directing upshifting until the engine speed continues to be not lower than the preset value for a predetermined time interval, an engine speed increasing rate detector for detecting the rate of increase of the engine speed, an engine load increasing rate detector for detecting the rate of increase of the engine load, and a delay time setting circuit which receives the outputs of the engine speed increasing rate detector and the engine load increasing rate detector, and makes the predetermined time interval shorter as the engine speed increasing rate increases and longer as the engine load increasing rate increases.

Abstract: A fuel control device for internal-combustion engines in which a proper correction value is calculated from the contents of memories corresponding to adjacent representative points, meeting every condition of the amount of mixture drawn in, by selecting representative points to represent the tendency of a flow-dependency characteristic change of intake sensor output, thereby obtaining a proper correction value in a region where the negative feedback of air-fuel ratio is controlled as well as in a region where the negative feedback can not be controlled.

Abstract: A cast article having a complicated shape of the appearance and the hollow can be obtained by forming a coating film on the surface of a pattern from a solvent-insoluble material to prepare a mold pattern, filling and hardening a molding material around the mold pattern, dissolving the pattern with a solvent, and removing the residue of dissolution and the coating film outside the mold.

Abstract: A mold forming method in which a pattern is made of an organic material such as foamed polystyrene and at least a portion of the outer or inner surface of the mold pattern is covered by a thin coating, and surrounded with a mold material. The pattern is then dissolved by a solvent, leaving the coating undissolved. The coating is finally removed by a solvent contained in a slip which is poured into the cavity provided with the coating.

Abstract: The present invention relates to a sodium-sulfur electric cell structure having a specific joint between a cathode tube and an anode tube. The cathode and anode tubes are each made of an iron-nickel base alloy and are joined to each other through the medium of a ceramic ring and an aluminum alloy insert provided on both sides of the ceramic ring. A chromium or chromium-rich layer is formed at the joint boundary between the insert and each tube. The sodium-sulfur electric cell having such a structure eliminates a problem of the occurrence of cracking, improves the airtightness and enables the production of large-sized electric cells.

Abstract: When a ceramic is bonded to a metal having a low thermal expansion, if a Cr layer of a Cr diffusion layer is formed on the surface of the metal and the ceramic is bonded to the metal through this Cr layer or Cr diffusion layer by an Al insert, a bonded structure having a good air-tightness and a high strength is obtained.

Abstract: A shifting timing indicating system for a vehicle includes a control circuit having an engine rpm sensor for detecting the engine rpm and a rpm comparator which receives the output of the engine rpm sensor and determines whether the engine rpm exceeds a preset value. The control circuit outputs a shift-up signal when the engine rpm exceeds the preset value. A shift-up indicator receives the shift-up signal from the control circuit and makes a shift-up display to direct the operator of the vehicle to shift up. An acceleration detecting circuit detects the rate of increase in engine load and the shift-up indicator is inhibited from making the shift-up display for a predetermined time interval which is extended with increase in the rate of increase in engine load.

Abstract: An acceleration detecting system for an internal combustion engine comprises air flow determining elements for determining intake air mass flow in an inlet channel provided to the engine and acceleration judging circuitry for judging an accelerating condition of the engine on the strength of an output of the air flow determining elements.

Abstract: The present invention relates to a method for bonding a non-oxide ceramic to a metal through an intermediate material comprising at least one member selected from metals of the Groups VIa and VIII of the Periodic Table. This method is suitably used for bonding of a structural part of a machine, an electronic part and the like.

Abstract: Aluminum or its alloy is subjected to surface treatment wherein the surface is heated and melted by the heat of an electric arc in an atmosphere of a mixture of inert gas and nitrogen gas. By this treatment, a dense layer of aluminum nitride is formed on the surface of aluminum or its alloy so that material of increased wear resistance is obtained.
