Abstract: PURPOSE:To prevent the occurrence of the actuating lag of a switching means and to prevent the occurrence of a torque shock, by a method wherein, in a device wherein natural frequency of a suction system is switchable by means of a switching means, control is made such that the switching means is actuated at the number of revolutions which is decreased as the speed of an acceleration state is increased. CONSTITUTION:In a 6-cylinder engine, the interior of a surge tank 1 is partitioned into first and second chambers 3 and 4 by means of a partition wall 2, and the ends on the upper stream side of manifolds 5a-5c, 5d-5f of cylinders, the ignition order of which is not in sequence, are open to the chambers 3 and 4. An opening 10, through which the two chambers 3 and 4 are intercommunicated, is formed in the partition wall 2, and a switching valve 12, adapted to open and close, is situated to the opening 10. The switching valve 12 is controlled such that it is opened at the preset number of revolutions by a control circuit 18 by means of an output signal from engine running state detecting sensors 14-17. Further, control is effected such that, during acceleration, the more rapid an accelerations state is, at the more early point of time the switching valve is opened and closed.

Title: Heater having shadow ring and purge on wafer surface
Inventor: SALVADOR UMOTOI
IPC: C23C16/455
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and method for control of a material deposition on wafer edges. SOLUTION: A wafer 20 is supported and heated below through a heater pedestal of a larger diameter than that of the wafer. A shadow ring 24 is disposed to surround the entire wafer without contacting to the wafer, thus masking a wafer annular zone near its edge. A purge gas flow is oriented to physically prevent a treating gas flowing from the front to the rear side of the wafer from depositing on a wafer mask part so as to suppress a treating fluid from depositing on the wafer, thus suppressing the deposition near the wafer edges. A purge gas manifold 26 concentrically disposed below the shadow ring 29 is defined by a tubular type annular zone round the heater pedestal to form a purge gas manifold outlet with a purge gap between the wafer and the ring 24.  The purge gas flows out from the purge gap to suppress the treating gas from entering this gap and more suppress the deposition on the wafer mask part.

Title: Control device of engine
Inventor: KOBAYASHI HIDEKI
IPC: F02P5/15
Filed: 1993-03-15
Abstract: PURPOSE:To prevent deterioration of a convergence property of slip control due to response delay of supercharging limitation at the time when it is changed over to the slip control by the supercharging limitation in a supercharging region when it is transferred to the supercharging region by accelerating operation during the slip control by fuel cutting or an ignition delay angle in a non- supercharging region. CONSTITUTION:By detecting slip (S2) by speed difference between a driving wheel and a driven wheel, when slip is generated in a non-supercharging region, slip control by fuel stop and an ignition delay angle is carried out (S6), and when slip is generated in a supercharging region, slip is restrained by supercharging limitation by a by-pass control valve (ABV) (S5). However, in the case when it is transferred to the supercharging region during the slip control by the fuel stop or the ignition delay angle, by limiting supercharging, the slip control by the fuel stop and the ignition delay angle is continued.

Title: Digital phase comparator
Inventor: FUKUHARA HIROSHIGE
IPC: H03L7/08
Filed: 1984-04-23
Abstract: PURPOSE:To attain exact phase advance and lag information even if two input signals are greatly different in period from each other, by providing a logic circuit which separates phase lag information and phase advance information from each other on a basis of one output of a digital phase comparator and one input signal. CONSTITUTION:When two input signals which are greatly different in period are supplied to a phase comparator 2, phase lag information Ud is outputted from an NAND gate 12. Meanwhile, phase advance and lag information are mixed in an output (a) of an NAND gate 13. A monostable multivibrator 14 is driven by lag information Ud, and NAND logic between its output Q' and the output (a) is NANDed to obtain an output (b). NAND logic between this output (b) and the output Q' of the monostable multivibrator 14 is NANDed to eliminate lag information, and only phase advance information is taken out. Then, phase advance information is outputted from an NAND gate 18. Thus, exact phase advance and lag information are attained even if two input signals are greatly different in period.

Title: Phosphoric acid type fuel cell
Inventor: TANUMA RYOHEI
IPC: H01M8/02
Filed: 1995-04-07
Abstract: PURPOSE: To prevent phosphoric acid from its movement and enable stable operation of a phosphoric acid type fuel cell to last for a long time by making a cooling plate in from of an asymmetric cooling plate on which plural grooves crossing each other longitudinally and laterally are formed on one main surface on the fuel electrode side. CONSTITUTION: An asymmetric cooling plate 18 is fabricated in a normal cooling plate 16 and plural cooling pipes 19 are embedded near a lower surface and guided to penetrate there and also roughness is formed on an upper surface by cutting many grooves crossing each other longitudinally and laterally on the upper surface and the upper surface becomes asymmetric against a flat lower surface. Since the heating sectional area of the plate 18 where grooves are formed is narrow, PAFC(Phosphoric Acid-type Fuel Cell) stack is assembled so as to increase the heat resistance between the plate 18 and a cell thereon.  Therefore, since the temperature on the cathode side is made higher than that on the anode side in all stacked cells, phosphoric acid drive power inside of the cell is offset so as to restrict movement of phosphoric acid during operation, thus continuous operation of PAFC is made possible.

Title: Phase film
Inventor: JO HISASHI
IPC: C08G64/00
Filed: 1994-04-20
Abstract: PURPOSE:To obtain wavelength dispersion of a large phase difference without coloring the image of a liquid crystal display device by constituting the phase film of polycarbonate having a repeating unit expressed by specified formula so that the film shows phase difference of specified conditions. CONSTITUTION:This film consists of polycarbonate containing >1mol% repeating unit expressed by formula. The ratio of phase difference Re(450)/Re(550) is specified to >1.080, wherein Re(450) is the phase difference at 450nm wavelength and Re(550) is the phase difference at 550nm wavelength. In formula, R1-R4 are independently hydrogen atoms or alkyl groups having l-5 carbon number. This polycarbonate contains the repeating unit expressed by formula by 1-100mol% of the total amt. If the amt. is <1mol%, the ratio Re(450)/Re(550) is smaller than 1.080, which is not preferable because enough compensation for phase difference is impossible.

Title: Broad band digital exchange
Inventor: SUMINO YUTAKA
IPC: H04Q11/04
Filed: 1990-03-29
Abstract: PURPOSE:To realize a broadcast function with less hardware by allowing a 2X2 unit switch to discriminate a broadcast signal cell by an identification bit provided to a cell and outputting an inputted cell to both of 2 output terminals. CONSTITUTION:A switch network 52 forms a Banyan network by using 2X2 unit switches 18 formed in an 8X8 exchange switch network as the unit. Thus, a transmission path of the inputted cell is switched by a switch network 52 to attain broad band exchange connection. An identification bit is provided to a header of an inputted broadcast signal cell and the 2X2 unit switch discriminates whether or not a cell is a broadcast signal cell by using an identification bit. When the cell is not the broadcast signal cell, the switch connection is decided by destination information stored in the cell and when the cell is the broadcast signal cell, it is outputted to both of the two output terminals. Thus, the broadcast function is easily realized with less hardware.
