Title: Air-fuel ratio control for internal-combustion engine
Inventor: IEZUKA ISAMU
IPC: F02D41/08
Filed: 1982-02-05
Abstract: PURPOSE:To reduce the repeated cycle period of a rich or lean condition in the air-fuel ratio by correcting the signal level for controlling an injection valve with integrated values varied when the throttle valve opening is at the idling position  or when the intake negative pressure is below the set value. CONSTITUTION:The air-fuel ratio is controlled by regulating the fuel injection of a fuel injection valve 15 with an electronic control unit 14 according to a rich signal and a lean signal from an O2 sensor 22. If the signal of the O2 sensor 22 changes from rich to lean or vice versas, the control signal level of the unit 14 is decreased or increased gradually by a specified integrated value. When with a throttle switch 23 ON, the idle operation is performed, while the signal level is increased by the first integrated value K1. When the operation is performed with a switch 23 OFF and a negative pressure switch 25 ON, the control signal level is increased by the second integrated value K2 (>K1).

Title: Deaerator
Inventor: MIZUKAWA TATSUO
IPC: B01D19/00
Filed: 1992-01-31
Abstract: PURPOSE:To provide a deaerator which continuously removes gaseous foreign matter included in liquid fluid. CONSTITUTION:A piston 20, a cylinder 19 and an actuator 26 constitutes a reciprocating pump. Liquid fluid sucked in the cylinder 14 at the A position pushes the liquid fluid itself into the 1st air chamber 28 in a process where the end of the piston 20 reaches the C position. Next, in a process where the piston 20 moves from the C position to the B position, the liquid fluid is depressurized and the included gaseous foreign matter is expanded and separated to accumulate it above the 1st air chamber 28. When the piston 20 reached the A position, the next liquid fluid flows in by the difference in pressure between inside and outside the cylinder 14 to push the gaseous foreign matter and defoamed liquid fluid into the 2nd air chamber 32. At this time, since a gas exhaust valve 40 is open, first, the separated gaseous foreign matter is exhausted to float a float 38 and simultaneously the gas exhaust valve 40 is closed, permitting the liquid fluid to be taken out.

Title: Direct injection type diesel engine
Inventor: NIIMURA KEIICHI
IPC: F02B3/06
Filed: 1995-02-03
Abstract: PURPOSE: To remarkably reduce NOX by simple structure and control by injecting part of exhaust gas which is in the state of later stage of combustion into a cylinder which is in a comparatively early state of a compression stroke. CONSTITUTION: A solenoid valve 9a is opened in a designated timing of later stage of combustion in an expansion stroke of a second cylinder B to inject part of exhaust gas in the second cylinder B from an exhaust gas injection nozzle 6a into a first cylinder A. The injection quantity is about several % of air supply, and set in the closing timing of the solenoid valve. The timing of injecting exhaust gas into the first cylinder A is set to be in a comparatively early stage of a compression stroke, which is lower than the pressure in the second cylinder B. Thus, exhaust gas is entrained with fresh air in fuel spray, so that premix combustion can be restrained by decrease of oxygen concentration, and the temperature of combustion gas is lowered to restrain reaction of oxygen and nitrogen, so that NOX can be reduced remarkably.  Thus, exhaust gas is introduced and injected sequentially into a third cylinder C, a fourth cylider D and the second cylinder B from the other cylinder.

Filed: 1986-01-28
Abstract: PURPOSE:To execute casting process stably by forming an tapered part of outer peripheral face of a connecting refractory and also arranging a fitting metal having chock-like section for the connecting refractory as tapering toward drawing direction. CONSTITUTION:The tapered part as an upgrade toward drawing direction of solidified shell at outer peripheral face of the connecting refractory 1 is formed and the fitting metal 10 for the connecting refractory is arranged in contacting with its tapered face and an end part of mold 3. The fitting metal 10 has the chock-like section and is suppressed by a flange 7 of the mold through a coned disk spring 11. Then, an annular space 12 enables sliding movement of the fitting metal 10, so as to compensate a difference of heat displacement between the mold 3 and the connecting refractory 1. In this way, the difference of displacement in accordance with a diameter expansion of the refractory 1 and the end part of the mold 3 at rising temp. is compensated by shifting of the fitting metal 10 to suppress the refractory 1. Therefore, casting process is executed under stable condition.

Abstract: PROBLEM TO BE SOLVED: To enable winning in a start winning hole regardless of adjustment of an obstacle nail by opening at least one electric start winning hole when the pattern at the time of stopping the display of a variable display device agrees with a preset pattern. SOLUTION: At least one of start winning holes 9a-9c, for example, a start winning hole 9a, is taken as an electric start winning hole controlled to be opened and closed by an electric driving means.

Title: Fuel feed control device for internal combustion engine
Inventor: OSAKI MASANOBU
IPC: F02D41/12
Filed: 1989-01-30
Abstract: PURPOSE:To correct a reduction amount correcting amount to a proper value through prediction of an amount of adhered fuel by a method wherein a reduction amount correcting amount is corrected as an amount equivalent to a total sum of an amount of fuel fed during a time between completion of acceleration or deceleration and the starting of deceleration is estimated. CONSTITUTION:During deceleration detected by a deceleration detecting means, a fundamental reduction amount correcting amount of a fuel feed amount is set by a fundamental reduction amount correcting amount set means, and an amount equivalent to a total sum of an amount of fuel fed by a fuel feed amount set means during a time between acceleration, detected by an acceleration detecting means, or completion of deceleration of acceleration and the starting of deceleration is determined by a fuel feed total sum computing means. A fundamental reduction amount correction amount is corrected according to a fuel feed total sum by a reduction amount correcting amount set means, a reduction amount correcting amount is set, and the set fuel feed amount is reduced for correction to feed it from a fuel feed means to an engine. During transition, e.g. slight step-on operation, an amount of adhered fuel is predicted to correct a reduction amount correcting amount to a proper value, and an air-fuel ratio can be prevented from brought into a lean region.

Title: Vertical magnetic recording and reproducing device
Inventor: MURAOKA HIROAKI
IPC: G11B5/02
Filed: 1985-01-31
Abstract: PURPOSE:To record and reproduce signals with a high resolution by providing a head only for DC erase in the leading side of a recording and reproducing head and erasing the DC of a recording medium before recording and impressing an impulsive recording current at the recording time so that the recording medium is magnetized in the direction opposite to the magnetization direction of DC erase and recording signals. CONSTITUTION:A uniform DC magnetic field is impressed to a recording medium 4 by a main magnetic pole 12 of the erasing head preceding a main magnetic pole 11 of the recording and reproducing head, and as the result, the recording medium 4 is in the one-direction magnetized state. Next, when signals are recorded by the main magnetic pole 11 of the recording and reproducing head, a demagnetizing magnetic field Hd acts upon a recording head magnetic field Hn to weaken the head magnetic field. However, contributions Hn1 and Hn2 from recording magnetizations adjacent to each other in the longitudinal direction in the recording medium act always in directions where the demagnetizing magnetic field Hd is cancelled. Thus, recording is performed with a good past characteristic without degrading the recording and reproducing resolution by the private erasing head, and a strong residual magnetization is formed in the recording medium because the influence of the demagnetizing magnetic field is reduce.

At this time, carriers (electrons) are injected into respective carrier traps in a heterointerface from the needle-shaped electrode 21 according to the recording information, and information is recorded. When recorded information is read out from the recording medium 10, electrons are injected locally from the needle-shaped electrode 21 at the cantilever 22 into a trap in an SiO2 /SiN interface and into a trap in an SiN silm.  A difference in the amount of an electric charge generated locally is detected by the distribution of a capacitance.
