Title: Intake/exhaust valve controller for internal combustion engine
Inventor: TISCHER DIETER
IPC: F01L9/20
Filed: 1999-11-12
Abstract: PROBLEM TO BE SOLVED: To simply and surely perform an operation in a high switching frequency, and adapt a valve controller to an internal combustion engine of high rotating speed by arranging a piezoelectric element for operating a valve element for controlling flow-in/out of a pressure medium to a regulating element capable of moving with the pressure medium against reaction for opening an intake/exhaust valve. SOLUTION: When current is passed to a piezoelectric element 1, a valve element 3 is separated from a valve seat with a tappet 2. In this time, a hydraulic medium flows into a pressure chamber 14 through a pressure pipe 7, a valve chest 4, and a supplying pipe 10. Both throttle parts of the supplying pipe 10 and a tank pipe 12 are followed with each other so as to generate pressure which is necessary for moving a regulating piston 15 in the pressure chamber 14 by the hydraulic medium. In the case where force generated by necessary pressure is larger than reaction pressure acted on a bucket tappet 20 by a compression spring 21, the regulating pin 15 is moved against force of the compression spring 21, and a valve head 23 is not moved to an opening position. When the regulating piston 15 is moved to a cylindrical chamber 17, an intake/exhaust hole 24 is opened.

IPC: E02F9/26
Filed: 1994-12-01
Abstract: PURPOSE: To prevent breakage of a limit switch for sensing the boom angle and generation of error in sensing by mounting the switch in a position under a boom installed on the body. CONSTITUTION: A limit switch 33 for sensing the angle of a boom 20 senses the angle of a boom cylinder 26 based upon the fact that the cylinder angle corresponds unumbiguously to the angle of the boom 20. When the boom 20 moves in the upward direction to cause also lifting of the cylinder 26, its oversurface is lifted by a rod for opening/closing the contact of the switch 33, and the built-in contact of the switch 33 is changed over. Using bolt, a mounting plate of switch 33 is installed on the vertical plate part of a bracket fixed to a frame for installation of the cylinder 26 furnished on an upper revolving element 1c. Thereby the switch is protected againt dropping matter such as earth and sand or collision of any object owing to installation of the switch under the boom 20 to lead to prevention of breakage of the switch 33 and generation of error in sensing.

Inventor: KUME TAKAO
IPC: F16C13/00
Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To reduce the curling to toner and nontoner image sides of a recording material by fixing the recording material carrying toner images of plural colors, without winding it on a fixing roller, even if the direction of ejecting the recording material is on the side of the fixing roller. SOLUTION: The rubber hardness of the elastic layers of the fixing roller 1 and a pressure roller 2 is a low hardness of <=5 deg. (JIS A), so that not only the elastic layer of the pressure roller 2, but also the elastic layer of the fixing roller 1 which is relatively thin and high in hardness is deformed in a nip, to make it a comparatively flat and small radiused shape fixing nip. Thus, the recording material is ejected to the side of the fixing roller 1, but the deformation to the toner or nontoner image side during the fixation of the recording material can be suppressed, so that the recording material 1 is prevented from winding on the fixing roller 1 and a curling quantity can be suppressed small.

Filed: 1997-11-27
Abstract: PROBLEM TO BE SOLVED: To provide a treating liquid discharge nozzle of a substrate treating device by which the whole treating surface of a substrate can be subjected to uniform treatment. SOLUTION: A treating liquid discharge nozzle 7 is provided with a discharge part 7a that plural discharge ports 7a1 -7a7 which are elliptic slots for discharging a developer are arranged in a single rank on the back surface thereof. When the developer is fed to the treating liquid discharge nozzle 7 from a liquid feeding pipe 8a, the developer is discharged from each of the discharge nozzles 7a1 -7a7 . At this time, the developer discharged from each individual discharge nozzle tapers off as it leaves the discharge nozzle. However, since the developer discharged from the whole discharge part 7a becomes in the shape of a belt toward the substrate as a whole, the treating liquid discharge nozzle 7 discharges the developer uniformly all over the treating surface of the substrate. As a result, the substrate can be subjected to uniform treatment.
