Title: Speaker cable
Inventor: KIMURA HAJIME
IPC: H01B7/36
Filed: 1992-05-28
Abstract: PURPOSE:To make a speaker cable usable freely as a star quad type cable or as a by-wiring connecting system cable by coloring an insulating material of an insulating wire core, and providing an identification means. CONSTITUTION:Four insulating wire cores 2, 3, 4 and 5 being collected in a common sheath 1 are formed so that outer diameters can be uniformized with each other by applying an insulating material 7 on the circumference of respective conductors 6, and are constituted of the two wire cores 2 and 3 having a relatively large conductor cross sectional area and the small wire cores 4 and 5. As for these wire cores 2 and 3, the insulating material is colored by a specific color A, and as for the wire cores 4 and 5, the insulating material is colored by a specific color B, and fellow members having the same conductor cross sectional area are treated as the same insulating material. A straight line shape marking 8 is given to the wire core 2 and the wire core 5 as an identification means by using a color C different from those of the insulating materials. Since the fellow wire cores 2, 3 and 4, 5 having the same color insulating material are adjoined to each other and the fellow wire cores 2 and 5 having the marking 8 are arranged on a diagonal line, the convenience in use can be improved.

Title: Freshness retaining agent
Inventor: AOKI MASAO
IPC: A01N37/44
Filed: 1995-05-10
Abstract: PURPOSE: To obtain a freshness retaining agent composition, excellent in safety and economical efficiency, enabling the supplement of nutrients and retention of the freshness and adaptable to cut flowers, vegetables, fruits, etc., by combining specific two kinds of compounds. CONSTITUTION: This freshness retaining agent composition uses a urea-calcium chloride salt and α-aminoisobutyric acid or its salt in combination. The composition is preferably an aqueous solution containing about 0.1-50% urea-calcium chloride salt and about 0.1-20% α-aminoisobutyric acid or its salt. The urea- calcium chloride salt in the composition converts nitrogen components and calcium components into a form readily absorbable into a plant body and effects as nutrients by an increase in the absorbed amount of an ammoniacal nitrogen fertilizer in the plant body can be increased and the plant body can be made healthy by the moderate absorption of the calcium components in the plant body. Furthermore, the absorbed amount of the acid in the plant body can moderately be increased by synergistic effects thereof with the α-aminoisobutyric acid or its salt.  Thereby, generation of ethylene is suppressed.

Title: Controller for spot welding machine
Inventor: NODA TAKUTSUGU
IPC: B23K11/11
Filed: 1993-06-08
Abstract: PURPOSE:To suppress generation of expulsion and surfaces flash and to perform welding with the uniform welding nugget diameter by detecting the voltage between electrodes, comparing a voltage value or its increasing rate with a reference value to predict generation of expulsion and surface flash and taking a measure to meet the situation according to its predicted result. CONSTITUTION:The expulsion and surface flash generated from the interval between metallic sheet materials to be welded can be suppressed by supplying a current reduced by teh specified quantity than the usual current quantity only for a period of a specified period tw1 during welding energizing. Experiment confirms that the expulsion and surface flash are easily generated during the period of this period tw1. Further, since the presence or absence of generation of the expulsion and surface flash is predicted by whether or not the voltage between electrodes during welding exceeds the reference value, generation of the expulsion and surface flash can be suppressed surely and effectively. While the period tw1 is the period when an area of a current path between the materials to be welded is going to expand suddenly, a welding current Iw is reduced by DELTAIw1 and the area of the welding current path is expanded smoothly during this period, by which generation of expulsion and surface flash is suppressed.

Title: Oil pump
Inventor: MORI FUMIAKI
IPC: F01M1/16
Filed: 1983-07-29
Abstract: PURPOSE:To enhance the output efficiency of an engine to obtain the effect of energy saving, by controlling the opening pressure of a relief valve in a flow passage with a fixed rate in accordance with variations in the detected rotational output power of the engine, so that a necessary but minimum amount of appropriate oil is fed into the engine. CONSTITUTION:When the rotational speed of the engine becomes high, the rotational speed of a gear pump 7 rises so that hydraulic pressure is increased. Simultaneously, a drive shaft 10 is rotated by a gear 11 meshed with a drive gear 9 to rotate a flyweight 13. The higher the rotational speed of the flyweight 13, the wider weight pieces 14 open under centrifugal force so that actuating pieces 15 rise up. Accordingly, a slide sheet 20 is compressed overcoming the tension force of a spring 22, in order to increase the opening pressure of a valve element 19. When the hydraulic pressure becomes higher than that required, the valve element 19 is depressed so that hydraulic oil flows out from a discharge port 16 to maintain the hydraulic pressure at a predetermined value, thereby automatic control may be made such that a necessary hydraulic pressure is fed to an oil gallery.
