Title: Solenoid valve system driving control device
Inventor: KAMIMARU SHINJI
IPC: F01L9/20
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To reduce shock caused at the time of the maximum opening and seating of a valve, and reduce noise by temporarily cutting off current-carrying to an electromagnetic coil for closing valve at a timing just before seating of the valve, when the valve is closed, and controlling deceleration of moving speed at the time of seating of the valve. SOLUTION: An intake solenoid valve system consists of a valve 7a, a valve closing electromagnetic coil 8a for opening/closing operating the valve 7a, a valve opening electromagnetic coil 9a, a valve opening spring 11a, a valve closing spring 12, and the like. When the solenoid valve system is closed, the valve opening electromagnetic coil 9a is made in a non-conductive condition, current-carrying of the valve closing electromagnetic coil 8a is carried out, and then, valve closing operation is carried out. In this time, the valve 7a is attracted in a seating position direction by magnetic force of the valve closing electromagnetic coil 8a, and current-carrying to the valve closing electromagnetic coil 8a is not carried out temporarily at a timing when the valve 7a is attracted to just before seating position.  It is thus possible to decelerate valve moving speed, and it is also possible to reduce shock and noise caused at the time of seating.

Title: Processing system for set of small area continuous drawing coordinates
Inventor: MUTOU TAMAE
IPC: H04N1/393
Filed: 1989-09-04
Abstract: PURPOSE:To shorten the calculation processing time and the drawing processing time for coordinate transformation of drawing coordinates by omitting the processing of later one of adjacent coordinates at the time when the distance between coordinates of two adjacent points is shorter than a preliminarily set discrimination area value. CONSTITUTION:A discrimination area lambda to be preliminarily set is set based on the reduction rate for coordinate transformation. A set of small area continuous drawing coordinates of a coordinate system is defined as {(X1,Y1), (X2, Y2),...,(Xn, Yn)}, and the processing of coordinates (Xi+1, Yi+1) is omitted in the case of DELTAi<lambda where DELTAi is the distance between drawing data of two adjacent points, and the processing is repeated with next coordinates of two adjacent points as the object.

Title: Buffer for crawler
Inventor: TANAKA SOTARO
IPC: B62D55/112
Filed: 1984-11-02
Abstract: PURPOSE:To make constant buffering performance keepable all the time as well as to aim at the promotion of dispensing with maintenance and inspection, by forming a variable pressure relief valve with a hydraulic cylinder, a valve and a spring, while relieving oil in an adjuster cylinder and making it absorb impact force. CONSTITUTION:When impact force occurs in a crawler, a piston 15 moves to the right, making a spool 32 move to the right, and ports 31f and 31a as well as ports 31e and 31c are all interconnected with one another, then 31e and 31b are intercepted, whereby discharge oil out of a cylinder 13 enters a cylinder chamber 25. On the other hand, a piston 23 moves to the left, proportioning it to a traveled variable, while a compressed variable of a spring 35 is proportioned to the traveled variable. Next, when force of the spring 35 exceeds pressure inside a port 31d, the spool 32 moves to the left whereby the port 31f is closed and the piston 14 is locked, while these ports 31b and 31e are interconnected with each other, causing the piston 23 to move to the right. Here, pressure in the chamber 25 goes up and if this pressure is not more than that of a cylinder 13, the piston 23 is also locked whereby force to be added to a rod 15 is quickly reduced down and after locking, the piston 14 is restored and buffers the impact force.
