Title: Bit map storage device
Inventor: NAKAMURA HIDEKI
IPC: G06T1/60
Filed: 1990-05-16
Abstract: PURPOSE:To draw vertical and horizontal lines at a similar speed by activating or inactivating a prescribed control signal by a control means and changing the arrangement of addresses. CONSTITUTION:When a control signal is inactivated, the Yo terminal of an address decoder 1 is active, the control means activates chip selectors 12, 13 and inactivates the chip selectors. The signal from the Yo terminal passes the selectors 11 and 13 and enters into chips 2 to 4. In this status, the chips 2 to 4 are selected, data are connected to data buses D0, D1, D7 and addresses are horizontally arranged. When the control signal is active, selectors 11 to 15, 19 are activated, the data are connected to the data buses D0, D1, D7 and the addresses are vertically arranged. Thus, the arrangement of the addresses can be changed to the vertical or horizontal direction by activating or inactivating the control signal by the control means. Consequently, both the horizontal and vertical lines can be drawn at the similar speed.

Title: Method of casting pressure die
Inventor: IBAN DEIMOFU NIKOROFU
IPC: B22D18/00
Filed: 1983-07-13
Abstract: 1. Pressure casting process in which the melt is conveyed from a melt container (1) through a duct (2) for material to a hollow chamber of a casting mould (3) under the effect of a pressure differential between the melt container (1) and the casting mould (3) and in which, after the filling of the hollow chamber (4) of the casting mould (3), the melt is cooled at additionally produced elevated pressure, with the melt being exposed in the casting mould (3) to a double-sided final pressing, characterised in that a residual space (5) of the casting mould (3) is exposed during the charging to an essentially elevated additional gas pressure as remotely applied final pressure and this increased additional gas pressure is balanced by means of a variable counter pressure on the side of the casting entry opening as casting side final pressure until there is complete charging of the casting mould.

Abstract: PURPOSE:To reduce the barrier height of an SBD electrode without breaking a shallow p-n junction within a semiconductor device provided with an ohmic contact electrode and a Schottky barrier diode (SBD) on a semiconductor substrate. CONSTITUTION:A part 7a to from an ohmic contact electrode and another part 1a to form an SBD electrode are made into window on the surface on an n type silicon semiconductor substrate 1.

Next Ti.W is sputtered to form a Ti.W film 11 on overall surface of pure Al. Then unnecessary pure Al-Ti.W film 11 is removed leaving the SBD electrode only to form an Al-Si film 12 coming into contact with an emitter n<+> type region on overall surface by evaporating Al containing Si. Finally an ohmic contact Al-Si electrode (wiring) 12 may be patterned simultaneously slipped out of the position of SBD electrode made of pure Al-Ti.W to form an Al-Si wiring 12a connecting to said wiring 12 to produce the desired electrode.

Abstract: PURPOSE: To improve the air flow speed which passes through a venturi section at low speed operation and promote the atomization of fuel by providing the respective paths which communicate a suction piston atmospheric pressure chamber with throttle valve upper and lower regions and a throttle in each path.  
     CONSTITUTION: A variable venturi type carburetor communicates the negative pressure chamber 13 of a movable suction piston 7 with the negative pressure region on the lower venturi section 11 and an atmospheric pressure chamber 12 with the atmospheric pressure occurrence region on the upper venturi section 11. In this case, the atmospheric pressure chamber 12 communicates with the negative pressure occurrence region on the lower throttle valve 2 through the negative pressure path 15 with a throttle diaphram and with the above atmospheric pressure occurrence region through the atmospheric air-ventilating hole 10 with a diaphram 20 in the same manner. At the low exhaust when the degree of opening of a throttle valve 2 is small, this permits the suction negative pressure on the lower throttle valve 2 to be guided to the atmospheric pressure chamber 12, the piston 7 to move right, the opening cross-section area of the ventruri section 11 to be narrowed, and the suction air flow speed to be improved.

Filed: 1991-05-31
Abstract: PURPOSE:To reduce the occurrence of read-write errors of data, even if there is any defect or flaw in a recording medium in a region for synchronization codes to be written. CONSTITUTION:A synchronization code detection means 12 inputs a code signal Sc read from a disc 1 and generates a detection signal DS when the detection means detects that the predetermined number or more of synchronization codes Sc are contained in that signal. A mask means 40 inputs a data code signal Sd from a data separation circuit 10 to one input of the means and a signal DS from the other input via OR gate 41 and gives its output to the encoder- decoder circuit 21 of a read-write means 20. The gate 41 receives the signal DS to its one input and a mask-canceling signal MS to the other input. Then, at the time of writing data, the gate conducts the read-verification of written data under the condition that the masked state for the signal Sd is canceled by the signal DS after writing, and, at the time of reading data, the gate reads the data under the condition that the masked state for the signal Sd has been canceled.

Abstract: PURPOSE:To improve the strength of a bulb near the sealing section and reduce its damage when an end plate and the bulb are sealed by glass frit in a groove provided on the surface of the end plate by forming a rounded storage pool that protrudes at the outside all over the circumference at the periphery of the opening end of the bulb. CONSTITUTION:A rounded storage pool 12 that is formed at the opening end 2 of a bulb 1 and is protruded at the outside is received by a bulb receiving groove 7 and is sealed on an end plate 3 by glass frit 8. Consequently, heat capacity is increased. Thus, the temperature difference generated between the bulb 1 of the sealing section and the end plate 3 in the cooling process of the sealing process is reduced and the stress applied to the bulb 1 in the vicinity of the sealing section is also reduced. In addition, since the thickness of the glass for a section 9 to which the shear stress of the bulb 1 of the sealing section is applied is thick, the strength for the shear stress is increased. Accordingly, the strength of the bulb 1 in the vicinity of the sealing section is improved sharply.
