Title: Make/break control system for capacitor
Inventor: SASAKI FUMIO
IPC: G05F1/70
Filed: 1986-06-03
Abstract: PURPOSE:To prevent the hunting of light load together with reduction of the make/break frequency of a capacitor in order to increase the lifetime of a switch, by combining the power factor control system and the reactive power control system with the make/break control system for plural phase advance capacitors used for improvement of the power factor. CONSTITUTION:The valid component of the power or current vector supplied to a load and plural phase advance capacitors from an AC power supply is set at a horizontal axis with the invalid component of said vector set at a vertical axis respectively on a vector plane. Under such conditions, the present make/break states of those phase advance capacitors are held as they are as long as the power or current vector is set inside the 1st curve L1 and the 1st straight line N1 and also within the 2nd curve L2 and the 2nd and 3rd straight lines N2 and N3 respectively. Then these capacitors are successively made when the power or current vector is set outside the curve L1 and the line N1 and then broken successively when those capacitors are set outside the curve L2 and the 2nd and 3rd lines N2 and N3.

Title: Manufacture of prefoam for metal-based composite material
Inventor: SANO YOSHINOBU
IPC: C04B35/80
Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To prevent the degradation of toughness of a metal-based composite material by preliminarily baking a reinforcement material at a temperature immediately below the melting point of the reinforcement material before forming the reinforcement material, forming the obtained preliminarily baked body, and then performing the main baking. SOLUTION: Only a reinforcement material 1 is used for a raw material, and no inorganic binder is used. The reinforcement material 1 is placed on a pan 12 in a baking furnace 10, and preliminarily baked using a heating body 11. The temperature of the preliminary baking is immediately below the melting point of the reinforcement material 1, and more specifically, in the temperature range from the melting point to the temperature lower than the melting point by 100 deg.C, and the reinforcement material is preferably maintained at that temperature for at least one minute. The obtained preliminarily baked body 2 is charged in a die 13, and a die of complicated shape is pressed by a preform forming machine 15 from the above to form the preliminarily baked body into a desired shape.  The formed preliminarily baked body 2 is taken out and placed in the baking furnace again for the main baking. The temperature and the time required for the main baking may be the same as that in baking a regular preform. A preform 3 of complicated shape can be obtained thereby.

Abstract: PURPOSE:To reduce the distance between word lines and implement the high integration and the miniaturization, by forming a source line with a conductive film patterned on a semiconductor substrate so as to connect each source region of a plurality of memory cells arranged in the direction of word line. CONSTITUTION:A source line SL to commonly connect a plurality of source regions 22 arranged in the direction of word line WL is formed between two word lines WL adjacent to the source regions 22 on a semiconductor substrate 20 in contact with the source regions 22. That is, the source line SL is buried in a source contact hole 32 formed between side walls 31 in a self-alignment manner. The source line SL is made of a polycrystalline silicon film having a low resistance through adding phosphorus.
