Title: Driving power transmission and imaging system
Inventor: TAKAYAMA SEIICHI
IPC: H02P5/69
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To synchronize a rotary load constantly by compensating for the rotational fluctuation of at least one of two rotary loads coupled through a gear system. SOLUTION: The driving power transmission comprises a main motor 2 for rotary driving a first load roll 1, and a second load roll 4 rotary driven by the main motor 2 through a power transmission gear system 3. An auxiliary motor 5 disposed in the driving system for second load roll 4 is coupled through a one way rotary clutch 6 for transmitting the rotary driving power only in the rotational direction of the load roll 4 such that the rotary torque is not added to the second load roll 4 at the steady rotational speed produced by the main motor 2 but imparts a predetermined torque to the second load roll 4 at a speed lower than the steady rotational speed. The one way rotary clutch 6 transmits a rotary torque from the auxiliary motor 5 to the second load roll 4 as the rotation speed decreases thus compensating for the rotation speed of second load roll 4.

Abstract: PURPOSE:To efficiently execute washing of supply pipes and a coater, removal of bubbles and liquid replacement and to decrease the time for changing over a coating liquid and liquid loss by drying at least the slit part of the coater after washing of the coater, then supplying the coating liquid to the coater and applying the coating liquid. CONSTITUTION:The operation in the case of a change over from the state in which from the common supply pipe 20 to the coater 30 are filled with the coating liquid stored in a coating liquid tank 10 to the coating liquid stored in a coating liquid tank 12 is executed by first washing the common supply pipe 20 and the coater 30 with the liquid in a washing liquid tank 27. The washing liquid and bubbles remaining in the supply pipe 20 and the coater 30 are then replaced with deaerated water by the liquid in a deaerated water tank 24. The washing liquid and bubbles are then discharged. Further, the expulsion and drying of the deaerated water in the coater 30 are executed and the liquid in the coating liquid tank 12 is fed by driving a liquid feed pump 21 by which the deaerated water in the line is replaced with the liquid in the coating liquid tank 12. Since the inside of the coater is dried, the generation of the bubbles in the coater does not arise even if the coating liquid is directly supplied thereto.

Filed: 1996-07-22
Abstract: PROBLEM TO BE SOLVED: To provide a method selectively prefetching a line M+1 from an L2 cache or a main memory to an L1 instruction cache in executing a line M. SOLUTION: When an unsolved branch exists in an undetermined line M, a line M+1 is predictive and the line M+1 is prefetched to an L1 instruction cache not from a main memory 115 but from an L2 cache 120.

Title: Electromagnetic type fuel injector
Inventor: ISHIKAWA TORU
IPC: F02M51/06
Filed: 1987-08-03
Abstract: PURPOSE:To prevent the generation of fuel vapor around a valve body and prevent the reduction of the engine output by forming a fuel passage which passes through the inside of a movable element from the vicinity of the joint part between the movable element and the valve body and communicates to the opposed surfaces of a stator core and the movable element. CONSTITUTION:A movable part consisting of a plunger 4, rod 5, and a ball valve 6 is formed at a valve guide 7, opposed to the top edge of a stator core 2. When an electromagnetic coil 15 is deenergized, the ball valve 6 closes a seat surface 8. The fuel vapor in a guide ring 36 flows out into a passage 22 from a hole 60. Fuel leaks, lubricating the sliding surface between the hole 60, inner wall of the core 2, and the guide ring 36, and passes through the passage 22. Therefore, the generation of fuel vapor around the valve body is suppressed, and the reduction of the engine output can be prevented.

Title: Air-fuel ratio control device of engine
Inventor: SAITO YOICHI
IPC: F02D41/14
Filed: 1997-07-17
Abstract: PROBLEM TO BE SOLVED: To suppress occluded NOx from exhausting when the temperature of NOx occlusion type catalyst is lowered to a temperature or below at which NOx can be reduced. SOLUTION: When a catalyst temperature TC is lower than a set value TCS (S55) and an operation is idle (S56), a coefficient of lean reduction amount KLEAN which determines a fuel reduction rate to obtain a proper lean air-fuel ratio according to an engine operating area is updated using a set value KLNS for correcting the air-fuel ratio to the lean side to a degree that an idle stability is not hindered (S57). Also the coefficient of lean reduction amount KLEAN is given as a loss item to various types of correction items set according to the engine operating conditions, and a target equivalent ratio KTGT expressed as the inverse number of an excess air ratio λ is calculated (S58).  By this, when the temperature of an NOx occlusion type catalyst is lowered than a temperature at which NOx can be reduced, the target air-fuel ratio is corrected so that the air-fuel ratio is not brought to a stoichio or rich side so as to suppress occluded NOx from exhausting.

Title: Internal matching transistor
Inventor: GOTO KIYOTAKE
IPC: H01L23/66
Filed: 1999-07-07
Abstract: PROBLEM TO BE SOLVED: To prevent low frequency oscillation during operation in high frequency band by providing a stabilization circuit comprising a resistor grounded through a resistor to avoid oscillation in the vicinity of a semiconductor element in a package. SOLUTION: The internal matching transistor 1 comprises semiconductor elements 2a-2d, input impedance matching circuits 3a-3d, output impedance matching circuits 4a-4d, and stabilization circuits 5a-5d. Since the impedance in the low frequency band is approximate to the impedance in the high frequency band in the vicinity of the semiconductor elements 2a-2d, corresponding anti-oscillation stabilization circuits 5a-5d are formed, respectively, in the vicinity of field effect transistors 2a-2d and field-effect transistors 2a-2d in same package. Since gain in the low frequency band is lowered by suppressing the influence of gain drop in the fundamental frequency band, low frequency oscillation can be suppressed. Furthermore, anti-oscillation countermeasure is not required outside the package.
