Filed: 1985-09-26
Abstract: PURPOSE:To changeover a state into an automatic reception even when no person resides in the vicinity of an incoming side equipment by operating an automatic reception function in the non-operating state according to the timing detecting that a call signal detection section detects the state without call signal incoming. CONSTITUTION:When a call signal comes from a trunk line 2, a telephone set 1 rings a bell.

Title: Measuring method for very small dimension
Inventor: FUJITA HIROO
IPC: G01B11/02
Filed: 1989-08-18
Abstract: PURPOSE:To make it possible to perform the stable measurement of dimensions by computing the dimensions of the first - third members based on the amount of the polarization of the light between the respective positions of the first and third, the third and fourth and the fourth and second edges. CONSTITUTION:Laser light 110 from a laser light source 10 is projected on a material to be measured 12 as laser beam 119 through an optical system 11. The light is deflected. Then the laser beam 119 which is reflected from the material to be measured 12 is detected with an optoelectronic transducing part 125 through the optical system 11. A reflecting intensity pattern is formed in a reflected-light-intensity-pattern forming part 13. The intensity pattern which is differentiated from the reflected-intensity pattern is formed in a differentiated- intensity-pattern forming part 14. Then, the two intensity-peak positions of the first and third members of the material to be measured 12 are detected in an intensity-peak position detecting part 15. The position where the absolute value of the differentiated value becomes the maximum value is detected in a first-edge-position detecting part 16. The positions of the edges of the first and second members and the second and third member are detected in a second-edge-position detecting part 17. The dimensions of each member between the four positions detected in the detecting parts 16 and 17 are computed in a dimension computing part 18. The difference between the driving voltages required for deflecting the light between the edges is converted into the actual dimension by using a stored dimension conversion coefficient.

Title: Semiconductor storage device
Inventor: KOSHIKAWA KOJI
IPC: H01L21/8242
Filed: 1993-08-26
Abstract: PURPOSE:To reduce charge and discharge currents of read buses by enabling all the read buses being accessible during a burst period by a column address of an external input, and by precharging them when a data amplifier is inactive. CONSTITUTION:A read bus couple ROT/Na is put in a precharged state when a signal DE turns 'L' and a first data amplifier disabled during a period when a data amplifier activation signal DEa is 'H' and when a signal YRD turns 'L' later and precharging is disabled. At the time when an input YON is 'L', an output of an NAND gate NA1 is 'H' even when inputs DEB and YRD are both 'L'. Therefore an output PROa remains 'H' and the read bus couple is kept precharged. Only the read buses being accessible during the burst period are precharged by a signal ENBL being 'H' only during the burst period after input of a read command and by a plate selection signal PDLa. By precharging the fewest necessary read buses, in this way, charge and discharge currents of the read buses are reduced to the utmost.

Title: Foil-wound transformer
Inventor: OKUBO HITOSHI
IPC: H01F27/32
Filed: 1984-10-11
Abstract: PURPOSE:To obtain the foil-wound transformer having a high insulating performance which is capable of offering a sufficient tension at winding a wire by composing an insulating sheet which is wound together with a metallic sheet out of two kinds of materials which are different in a tensional strength and a hermetic degree. CONSTITUTION:An insulating sheet 18 wound with being inserted between metallic sheets 7 is composed of lamination of a material 18a whose hermetic degree is 4,000 Gurley or below and a material 18b whose tensional strength is 14kg/mm<2> or over. The foil-wound transformer thus constituted can endure enough on the side of material 18b even a tension of about 10kg/mm<2> at winding a wire so that the winding does not become loose after winding the wire or drying. Also as the material 18b can stretch extremely long, the sufficient strength against shrinkage or extension due to a change of temperature can be obtained. Furthermore, because also against various mechanical forces at operation of the foil-wound transformer, the metallic sheets 7 and the material 18a which are interposed function as a cushion and absorb a slip shearing force acting between it and the metallic sheets, a damage on the insulating sheet 18 can be prevented.

Filed: 1995-08-21
Abstract: PROBLEM TO BE SOLVED: To make uniform the quantity of heat being generated from a device over the surface thereof by fixing an independent metal piece to a part of the surface of a shield case and projecting planar parts, in parallel with each other, from the surface of the shield case and the surface of a circuit board. SOLUTION: A heating device 3 is mounted on a circuit board 6 and brought into contact with an independent metal piece 1 having a planar part 5 formed on the shield case plane 2. This structure prevents the temperature in a unit from increasing over an allowable limit due to the heating device 3. When the position and the number of independent metal pieces 1 are set appropriately depending on the number, the quantity of heat and the mounting position of heating device 3, the shield case plane 2 can be used commonly. Since it is not required to prepare a machining die of the shield case for every product, rationalization can be achieved.
