Title: Static type semiconductor memory
Inventor: OCHII KIYOBUMI
IPC: G11C11/413
Filed: 1990-05-28
Abstract: PURPOSE:To prevent an abnormal current from flowing within respective memory cells on power source bumping by making a time constant when wiring within a memory cell array is charged/discharged larger than the time constant when the storing nodes of respective memories are charged/discharged. CONSTITUTION:When a time constant when internal storing nodes A and B are charged with a power source electric potential Vcc of power source wiring within memory cell array 12 is made as tauc and the time constant when the wiring 12 is charged with the power source electric potential Vcc of resistance wiring 15 is made as tauw, they are set to values so as to satisfy the relation of tauw>=tauc. Even when the electric potential of the wiring 15 ascends rapidly on power source bumping, speed on charging the wiring 12 becomes slow by the existence of a resistance element 16 by a constitution like this. Since the nodes A and B of the cell 11 are charged by the electric potential of the wiring 12, the charging speed of capacities C1 and C2 to exist in the nodes A and B becomes the speed close to the charging speed of the wiring 12 and TFTs Q4 and Q6 which are in an off-state within the cell 11 are not made on. As a result, a DC current is prevented from flowing between the electric potential Vcc and a ground electric potential in the respective memory cells.

Inventor: YUDASAKA MASUTOSHI
IPC: F17C3/04
Filed: 1982-08-09
Abstract: PURPOSE:To prevent any leakage from a tank reduce the concentration of stress and prevent the deformation of the tank, by interposing a material, having compressive strength almost equal to that of the side wall and bottom disc concrete, and an elastic modulus smaller than that of said concrete, in the joint part between the bottom end of the side wall and the bottom disc. CONSTITUTION:A corner member 3 made of material such as a lightweighted concrete, having compressive strength equal to a side wall and a bottom disc, and an elastic modulus smaller than that of said wall and disc is interposed in the joint part between the bottom end of the side wall 1 and the bottom disc 2. Accordingly, when the temperature is changed, the smaller elastic modulus in the joint part restricts contraction of the bottom disc with the reduction of concentrated stress to the joint part, and a stored material such as liquefied gas or the like is not allowed to leak. The bottom end of the side wall 1 can be elastically supported with integral construction in the horizontal direction, and deformation of the side wall 1 is restricted to a certain extent with the decrease of horizontal bending moment while the side wall 1 is left as holding its round shape, thus the quantity of iron reinforcing rods in the horizontal direction arranged in the side wall 1 can be decreased. Further the relative displacement is not generated between the side wall 1 and the bottom disc 2, and the necessity for any upper slab is eliminated.

Abstract: PURPOSE:To eliminate a torque ripple and to enhance the efficiency of a two- phase brushless motor by providing a demagnetizing interpole at the position of the specific angle from a pole inverting boundary of a main pole in a field formed with a portion which does not substantially generate a torque between main poles. CONSTITUTION:A 2-phase brushless motor is formed by opposing a rotor magnet having a field provided with an electroless pole 2 which does not effectively generate or weakens a torque along a rotating direction between main pole pairs N, S and a stator having an armature displaced at 180 deg. at the interval of two sides which contributes to the torque generation of 2-phase coil. In this case, an interpole 5 for demagnetizing a pole effective to generate a torque is provided at a position of approx. 90 deg. (gamma=90+ or -10 deg.) from the pole inverting boundary K of main pole pair. Thus, the reduction of the absolute torque is minimized to effectively reduce the torque ripple.

Filed: 1992-05-01
Abstract: PURPOSE:To perfectly shut off gas in a dry type dust collecting device by filling water into a gas turn-over part in a wet type dust collector arranged in parallel in the dry type dust collecting device and keeping the difference of the water level at above the pressure loss of the dry type dust collecting device. CONSTITUTION:In the case of changing over the operation from the wet system to the dry system, after opening shut-off valves 6, 8, a dry-system change-over valve 7 in the closed condition is gradually opened and also, the water is gradually stored into a mist separator part 16 in the wet-system primary dust collector 9. The water surface level is kept at the pressure loss of the dry type dust collector or above from the lower end of a flaring pipe 17 and gas flow in the wet system, i.e., bypass system in the dry type dust collecting device is perfectly shut off. Water sealing can be executed in a secondary dust collector 10 instead of the primary dust collector 9. By this method, the operation of the wet-system dust collecting device for the leaked gas is made unnecessary. Further, the shut-off valve in the bypass system can be unnecessitated and the equipment cost can be reduced.

Title: Valve drive method of internal combustion engine
Inventor: YAGI SHIZUO
IPC: F01L1/12
Filed: 1990-05-28
Abstract: PURPOSE:To control the output torque of an internal combustion engine for reducing resistance in a flow passage of fresh air and pumping loss and thereby improving fuel cost and output by closing an intake valve before a piston reaches the bottom dead point in the intake stroke during partial load operation, and thereby controlling the intake amount of fresh air. CONSTITUTION:During partial load operation of an internal combustion engine, the base circle of a cam 25a is in contact with the slipper face 26a of a locker arm 11a at a point Po. When a cam shaft support member swings to the outside in the direction shown by an arrow B during full load operation, the base circle of the cam 25a is brought into contact with the slipper face 26a. In this case, the rotation directions of an idler gear 22 and a cam gear 25a are set respectively in the directions shown by arrows (p, q). Consequently, due to the swing B of cam shaft support member to the outside, a cam gear 24a which rolls along the outer circumference of the idler gear 22 rotates counterclockwise as shown by the arrow (q) and the phase is delayed. Accordingly, the phase of the cam 25a is delayed so that the valve timing of intake valve is delayed.

Title: Electron gun for color picture tube
Inventor: NAIKI KAZUAKI
IPC: H01J29/50
Filed: 1981-09-02
Abstract: PURPOSE:To obtain an electron gun for an in-line-type color picture tube, in which the  resolutional characteristic of a main electron lens is enhanced, by making an overlapping hole of an anodic electrode which is formed of complete circular holes and an incomplete circular hole arranged alternately to face an overlapping hole of a focusing  electrode which is formed of incomplete circular holes and a complete circular hole  arranged alternately. CONSTITUTION:The off center distance (S2) of an anodic electrode 24 is generally slightly larger than the off center distance (S1) of a focusing electrode 23. The side opening  holes 24R and 24B of the electrode 24 are shifted outward from the side opening holes  23R and 23B of the electrode 23 so as to form a so-called equivalent inclined lenses at  the side opening holes 24R, 24B and 23R, 23B facing to each other, thereby making  both side electron beams to electrostaticly concentrate on a central electron beam in  the center of a picture surface. In an electron lens constituted from electrodes with the  above mentioned structures, the diameters of the opening holes (D1) and (D2) are larger  than the off center distances (S1) and (S2) between the opening holes arranged in in-line form without altering the off center distances (S1) and (S2) as usual. Therefore, the  spherical aberration of the electron lens is small.
