Abstract: PURPOSE:To perform collection of highly reliable information even on-board by a method wherein it is decided that abnormality occurs to a system when, after during operation in a feedback control mode, the number of revolutions of an engine enters a range of the number of revolutions centering around the target number of idle revolutions. CONSTITUTION:An intake amount of an engine is controlled by the ISC(Idle Speed Control) control part 60 of an electronic control device 25 through comparison of the target number of idle revolutions with the number of revolutions of an engine when the running state of an internal combustion engine is a feedback control mode. In this case, an elapse time starting from a point of time when the engine is brought into the feedback control mode is measured by a first timer 71. Further, it is detected by a number of revolutions of engine state detecting means 72 whether the number of revolutions of an engine enters a given rotation range centering around the target number of idle revolutions. A lapse time starting from a point of time when the number of revolutions of an engine enters a given number of revolutions range is measured by a second timer 73. When a second lapse time is continued for a given time, it is decided by a means 74 that a system is normal.

IPC: F03G7/00
Filed: 1996-07-23
Abstract: PROBLEM TO BE SOLVED: To reduce the extent of reverse thrust in a discharge cylinder as well as to make improvements in output efficiency by setting up plural pieces of those that convert a thrust direction of this discharge cylinder in opposition to a propelling cylinder into a turnover direction by dint of gears and so on, and linking up these elements with one another by means of leverage. SOLUTION: At a time when a forward propelling cylinder 11 is started in the forward direction, a pump 2 is driven and a normal back-pressure applying circuit 9 is pressurized, and thereby each back pressure part of two discharge cylinders 13 and 14 for both forward movement and backward movement is made into an equi- pressurized state. Each thrust of these discharge cylinders 13 and 14 is immovably placed at an equilibrium as two rack shafts 17 and 18 in mesh with turnover gears 19 and 20 are linked up with one another by a balance 25. Next, if an ahead valve 5 is opened, and ahead pressurizing circuit 7 is pressurized, the forward propelling cylinder 11 and the discharge cylinder 13 are made into a state of equi-pressurization, and a thrust is generated, thus moving the rack shaft 17 to the left.  At this time, an internal fluid turns to an equi-capacity round floe through a round flow circuit 26, and thus a continuous propulsive motion is carried out.

Title: Control method for brake
Inventor: MATSUOKA TOSHIYUKI
IPC: B60T13/66
Filed: 1982-12-20
Abstract: PURPOSE:To correspond a command value and a cylinder fluid pressure in a ratio of 1 to 1 by adding to or subtracting from the brake command a compensating value obtained from a measured value of hysteresis characteristics of the brake cylinder and a set pressure of a target fluid pressure. CONSTITUTION:Hysteresis characteristics of the air pressure of a brake cylinder 5 in response to a brake command E by a command unit 1 is measured. The air pressure at the time when the command E goes higher is hereby set as a target air pressure P. Therefore, the command E needs to be compensated only when it goes down. The compensating value is obtained from the measured value of the hysteresis characteristics and the target air pressure, and a compensating circuit 13 is set up to output such a compensating value. When the command E goes down, a comparator circuit 11 detects the decrease in the command E to cause a memory circuit 12 to output to the compensating circuit 13. The compensating circuit 13 outputs said compensating value to a computation circuit 14, and the computation circuit 14 outputs a signal which is the result of the command E subtracted by the compensating value to an electropneumatic conversion valve 3 through an amplifer 2. The valve 3 operates a relay valve 4 based on the outputted signal.
