Title: Digital-analog converter
Inventor: SEGAWA YUJI
IPC: H03M1/68
Filed: 1986-03-28
Abstract: PURPOSE:To reduce the number of resistors and switches and to prevent the montonousity from being loat by combining a specific resistor string D/A converter, a specific weighted resistor group and a specific switch group connecting/ disconnecting the resistor group. CONSTITUTION:In a multi-bit, e.g., 8-bit D/A converter, 15 (=16-l) sets of resistors (resistance R) in a resistor string are connected to the high-order 4-bit and the resistance of the weighted resistor group is selected as R/2,R/4,R/8 and R/16 according to the low-order 4-bit. Further, the connection/disconnection switch of the weighted resistors is switched according to the low-order 4-bit D0,Dl,D2 and D3 and the resistor string is switched according to the high-order 4-bit D4-D7. The sum of the resistances between reference power supplies Vr(+),Vr(-) is constant (=16R) even when the switch is changed over in any way. The output voltage is expressed in equation by the weighted resistor group and the resistance string, where V=Vr(+)-Vr(-) and D is a data of the relevant bit, 'I' or '0'. Thus, an 8-bit D/A conversion output isobtained aud 24 sets of resistors are enough for the titled converter.

Inventor: KOMODA NORIO
IPC: F02D23/00
Filed: 1984-04-11
Abstract: PURPOSE:To prevent the generation of knocking and plague on supercharging and reduce the air-fuel ratio by controlling the air-fuel ratio so as to be small when an electromagnetic clutch is connected and controlling the compression ratio so as to be large when the electromagnetic clutch is cut-off. CONSTITUTION:An electromagnetic clutch 11 is connected when the throttle opening degree TA increases over a predetermined opening degree TA0, and the electromagnetic clutch 11 is cut-off when the opening degree is smaller than TA0. When the clutch 11 is in connection state, a supercharger 7 is driven to feed a large amount of air and the fuel corresponding to the air. When the clutch 11 is in cut-off state, the supercharger 7 idly revolves, and the inhaled air amount is introduced into an engine. The piston 20 of a compression-ratio varying apparatus is driven rightward when the clutch 11 is connected, and the compression ratio is reduced, and the generation of knocking and plague is prevented. When the clutch 11 is cut-off, the piston 20 is driven leftward, and the compression ratio increases.

Filed: 1990-03-21
Abstract: PURPOSE:To improve a dynamic semiconductor storage device in degree of integration by a method wherein the width of a non-selection part of a memory cell in a direction in which a word line extends is formed smaller than that of a selection part. CONSTITUTION:The memory cells of a dynamic semiconductor storage device are formed into diamond shapes in plane figure, the width of the memory cell in a direction in which a word line extends is largest at a center where a bit connection hole 32 is located and becomes gradually smaller as the memory cell recedes from the center toward the outside. Therefore, the width of the memory cell at the non-selection part of a word line 24 in a direction in which the word line extends is smaller than that of the memory cell at the selection part. Taking advantage of that the memory cell is formed diamond in plane figure, cells are made as high in arrangement density as possible as compared with a case where a cell rectangular in plane figure is used. That is, diamond cells are arranged densely in a vertical direction. By this constitution, even if a cell is small in which at a non-selection part, a lower electrode 28a of a stacked capacitor is formed so as to occupy most of the area of the memory cell excluding the bit connection hole 32, whereby an electrode can be prevented from decreasing in area and memory cells can be improved in arrangement density without decreasing a storage device in capacity.

IPC: F04B49/06
Filed: 1990-03-20
Abstract: PURPOSE:To safety hold a pump well water level in a low position in the case a large quantity of rainfall is generated in a short time by determining an increase and a decrease of a final number of operation sets of a rainwater pump by combining an empirical inference means and a quantitative inference means. CONSTITUTION:In a quantitative inference means 14, the number of operating sets of a pump is determined by inferring an increase and a decrease of the number of operating sets of a rainwater pump from a relation of an inflow flow rate predictive value obtained from process data and a pump well water level predictive value. In this case, when a inflow flow rate to a pump well or a pump well water level is in an ascending tendency, an empirical inference means 15 infers an increase and a decrease of the number of operating sets of the pump from a relation of the pump well water level and a pump well water level varied state, corrects the increase and the decrease of the number of operating sets of the pump of a result of quantitative inference, based on a result of this inference and outputs it instead of the number of operating sets of the pump by the quantitative inference means 14. In such a way, even in the case a sudden variation of the pump well water level is generated, it is held stably in a low water level.

Title: Zoom lens for high magnification variation rate compact camera
Inventor: ITO TAKAYUKI
IPC: G02B15/16
Filed: 1988-03-25
Abstract: PURPOSE:To reduce variation in the curvature of field and to improve variable magnification ratio over entire variable magnification range by composing a 1st lens group of a lens group with small power and a lens group with positive focal length and varying a gap between those lens groups at the time of zooming. CONSTITUTION:The 1st lens group consists of a lens group 1a which has positive or negative focal length and a lens group 1b with positive focal length on the image side in order from an object side. Then when the variable magnification is varied from the short-focus side to intermediate focal length at the time of zooming, the gap between the lens groups 1a and 1b is increased, but when the variable magnification is varied from the intermediate focal length to the long-focus side, the gap is decreased to the contrary. The relative gap between the diverging surface of the lens group 1a and the diverging surface of the lens group 1b, therefore, varies. Consequently, the incident height of an off-axis light beam from the diverging surface varies to enable control over the curvature of field, thereby obtaining the zoom lens for the compact camera which has small variation in the curvature of field over the entire variable magnification range.

Abstract: PURPOSE:To thinly and uniformly form the layer thickness of developer on a developer carrier by press-contacting a layer thickness regulating member to the developer carrier by means of a magnetic field generating means which is provided in the rear of the layer thickness regulating member and magneto bodies inside the developer carrier. CONSTITUTION:Title device forms a developer layer by press-contacting the laminar layer thickness regulating member 4 of the developer whose one end is supported and the other end is free to the developer carrier 2 which carries and conveys the developer. In this case, the magnetic field generating means 5 and 6 are provided in the rear of the layer thickness regulating member 4, and by the magnetic power caused by the magnetic field generating means and caused by both this magnetic field generating means and a magneto body 3 inside the developer carrier, pressing power acts which press-contacts the layer thickness regulating member 4 to the developer carrier 2. Thus, when the magnetic field generating means are to generate a repulsive magnetic field, flocculated and turning-into-larger-particle developer is thoroughly removed. Moreover, since magnetic power caused by a magnet roller inside the developer carrier and the magneto bodies of the magnetic field generating means act on the developer, it is stirred and solved and is formed in considerably uniform and thin layer.
