Patent JP-H0562478-A (JP)
Title: Semiconductor memory
Inventor: KIHARA YUJI
IPC: G11C11/417
Filed: 1991-09-02
Abstract: PURPOSE:To suppress the generation of a noise at the time of the charge and discharge of a data reading line, and to attain a high speed access by suppressing a logical amplitude value by a converting means. CONSTITUTION:In an invertor 6, a Pch FET 6a is functioned as a diode, FET 6b and 6c are compensation-connected, each gate is common-connected in order to receive the output of a sense amplifier 2, and an Nch FET 6d is functioned as a diode. Thus, the drain potential of the Nch FET 6b is Vcc-VTHP by the ground voltage VTHP of the Pch FET 6a of the diode connection. The source potential of the Pch FET 6c is GND+¦VTHN¦ by the VTHN of the Nch FET 6d of the diode connection. Therefore, the logical amplitude value of the invertor 6 is limited, and a data reading line RD is operated between the GND+¦VTHP¦- Vcc-VTHN. When the sufficient large size of the FET 6a and 6b is obtained, the high speed of an invertor inverting time is attained for the reduced amplitude. The charge and discharge amounts can be reduced at the time of inversion, and the generated noise can be suppressed.

Title: Fluorescent lamp and luminaire
Inventor: ISHIZUKA MASAHIRO
IPC: H01J61/48
Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To reduce glare without degrading persistence characteristic by setting the amount by which a phosphor with a long persistence characteristic adheres to a first emission layer to a predetermined value. SOLUTION: A second emission layer 3 made from one or two kinds or more of phosphors is laid on top of a first emission layer 2 and over an opening 2a in the first emission layer 2. In forming the emission layers 2, 3, the direction of application for the formation of the second emission layer 3 is made opposite to that of application for the formation of the first emission layer 2, so that the overall film thicknesses can be made relatively equal. The amount of light emitted from the first emission layer is smaller compared with the amount of light emitted from the opening 2a, since absorption of light takes place at the first emission layer 2. Therefore, glare can be reduced during use in a direct luminaire.  Also, of the first and second layers 2, 3 formed one on top of the other over the inner surface of a glass bulb 1, the second emission layer 3 on the side of a discharge path is formed using a rare earth element phosphor and so can be excited efficiently with ultraviolet rays.

Title: Hierarchical motion compensation method for moving picture motion and vector interpolation predict method
Inventor: ENDO TAKASHI
IPC: H04N7/32
Filed: 1993-09-07
Abstract: PURPOSE:To reproduce a rough picture as required or to reproduce a detailed picture by selecting motion compensation for a higher layer or motion compensation for the higher layer in addition to motion compensation based on a motion vector of an apex of a lower layer. CONSTITUTION:When a discrimination processing section 2 starts reproduction by higher layer only at the start of processing, the discrimination processing 2 discriminates whether or not the reproduction by the higher layer only is to be executed. When the discrimination indicate an affirmative result, a processing 4 uses a motion vector of part of an apex belonging to the higher layer to execute motion compensation in the processing unit of a large hexagon. When the result of the discrimination processing section 2 indicates a negative result, a processing 6 uses a motion vector of part of an apex belonging to the lower layer to execute motion compensation in the processing unit of a small hexagon. Thus, the motion compensation for the higher layer only or the motion compensation for the higher layer in addition to the motion compensation of a motion vector of an apex of the lower layer is executed selectively.

IPC: E02D27/10
Filed: 1983-11-29
Abstract: PURPOSE:To reduce bending moment caused by displacement of the ground during the earthquake period by a method in which vertical forces are supported by a long pile, and the horizontal forces are supported by a short part embedment rigidly. CONSTITUTION:A steel tube 6 is joined with the head of a cast-in-place bottom- expanded reinforced concrete pile 7 and a footing 9, and in the portion other than the joined portion, the tube 6 is set with a small setting depth around the concrete pile 7 without contact. By the steel tube 6, the horizontal forces are supported, and by the concrete pile 7, the vertical forces are supported. The aperture 8 between the steel tube 7 and the concrete pile 7 is blanked or filled with soft soil. The vertical forces are supported by long piles, and the horizontal forces are supported by short parts rigidly with short embedment depths. The bending moment with the displacement of the ground during earthquake can thus be lessened.
