Title: Nos type semiconductor memory device
Inventor: MATSUI YOSHINORI
IPC: G11C11/407
Filed: 1989-08-30
Abstract: PURPOSE:To prevent current consumption increasing due to short-circuit between a word line and a digit line, etc., by providing a means which reduces a current between the word line and ground potential less than the one in the non-selection of a word line selection operation when a pre-charge operation is performed. CONSTITUTION:Gate potential G is connected to a node N1 in the inside of an X-decoder 1 via the transfer gate TG1 of a switching circuit 2, and also, to the potential H of an intermediate potential generation circuit via a transfer gate TG2. A signal phiA goes to a high level when the word line is selected, and a low level when the pre-charge operation is performed. In other words, the gate TG1 is turned on with the signal phiA when the word line is selected, and is turned off when the pre-charge operation is performed, and the gate TG2 shows a state opposite to that. Therefore, when the short-circuit occurs between the word line WL and the digit line D1, a current in a stand-by period can be prevented from increasing by reducing the gate potential G of a transis tor T10 when the pre-charge operation is performed.

Title: Vibro-isolator of vacuum pump
Inventor: OKAZAKI KOJI
IPC: F04B39/00
Filed: 1986-09-26
Abstract: PURPOSE:To reduce intake and exhaust noise and enable improvement of vibro-isolating performance by forming both an intake passage and an expansion chamber inside a thick block-type vibro-isolating rubber and mounting a vacuum pump above the expansion chamber. CONSTITUTION:When exhaust gas in a vacuum pump 11 is discharged from a discharge pipe 21 into an expansion chamber 9, said gas is expanded and then reduced in flow rate during discharge from the expansion chamber 9 into an exhaust passage 8. Since the ratios in the sectional area between the discharge pipe 21 and the expansion chamber 9 and between said chamber 9 and the exhaust passage 8 are specified, exhaust noise produced when the gas is discharged from the pump 11 is silenced and released into the atmosphere, whereby enabling noise reduction. When the pump 11 is driven by a motor, vibration is generated and transmitted to the contact face with a vibro- isolation rubber 1, however, the rubber 1 gains high resiliency due to its own resiliency plus the resiliency of the expansion chamber 9 as a thin support part 23 defined below the contact face of the pump 11 and the rubber 1. In addition, since the internal space of the expansion chamber 9 function as an air layer, the air pressure thereof provides the damping effort so that the vibration of the pump 11 can be dampened well.

Title: Vacuum tube and display device
Inventor: TSUKAMOTO TAKEO
IPC: H01J1/30
Filed: 1990-08-30
Abstract: PURPOSE:To improve a characteristic by changing the height of each electrode so that an electron emission direction can be completely unparallel to a substrate. CONSTITUTION:Electrons are emitted from the tip part of an electron emission electrode 4 based on the principle of field emission, in which a main element is biased between an electron emission electrode 4 and a drawing-out electrode 3 in vacuum and the latter is made positive electric potential. At that time, most of the emitted electrons are led to a gate electrode 2 and a collector electrode 1 by installing the drawing-out electrode 3 slightly under the horizontal direction of the electron emission electrode 4 in order to prevent the deterioration of a vacuum tube characteristic due to the spreading of the electrons. When electric potential applied to a gate is made negative at the time that the electrons pass the gate electrode 2, the electrons are decelerated and the number of electrons reaching the collector electrode 1 is reduced, and thereby amplification and oscillation actions can be surely made.

Filed: 1986-09-24
Abstract: PURPOSE:To detect the defective coating of a primer by specifying the colors on the surface of a material to be coated by the primary color which occupies the max. ratio among three primary colors and calculating the distribution rate of the same primary color component as the primary color which is previously specified among the three primary colors on the primer coated surface. CONSTITUTION:The image of the primer coated surface is picked up by a color image sensor 120 and is spectrally split to the three primary colors of light by a spectroscopic device of a sensor 129. The three primary colors are then converted to digital image signals of every one frame by A/D converters ADR, ADG, ADB or the like and are sequentially written into an image memory 130. The image signals stored in the memory 130 are stored through a bus B02 into a main memory 131 by the address signal from a CPU 134. On the other hand, the primary color signal which occupies the highest occupying ratio among the three primary colors constituting the colors on the surface of the material to be coated prior to the primer coating is specified and is preliminarily stored in a sub-memory 132. The ratio at which the same primary color component as the specified primary color occupies in the picked up image is calculated, by which the defective coating of the primer is detected with good accuracy.

Filed: 1987-09-10
Abstract: PURPOSE:To make it possible to cut off a small current securely by arranging an arc movement space to drive the arc to contact makers, and permanent magnets at the opposite side, and presenting an outer magnetic field in only one direction in the whole movement space of the arc necessary for extinction of arc. CONSTITUTION:At the opposite side of an arc movement space A formed between insulator plates 2 opposing each other parallel to a contact maker 4, that is, at the lower side of the contact maker 4, each bar permanent magnet 18 is furnished at each position striding the contact maker 4, unifying the magnetizing direction to the arc driving direction, and the two magnets are arranged in the reverse directions each other. Since there is an outer magnetic field only in the same direction in the arc movement space A, this outer magnetic field is added effectively to the driving magnetic field generated in the arc position by the current flowing passage of the cutting current itself when the small current is cut off. Consequently, the arc is driven up to the final arc extinction position to come to extinct the arc without disturbing the drive of arc.
