Abstract: PURPOSE:To increase the fluidity and make contact with a member to be alid uniform by forming minute and sharp recessed and projected parts on the surface of mother material on the slide side with the member to be slid, and applying plating which is softer than the mother material on it. CONSTITUTION:A bearing metal 1 is constituted, with an aluminum metal 2 as a mother material, by forming minute and sharp recessed and projected parts 3 on the surface of aluminum metal 2 on a surface 11 on the slide side with a crank shaft B, applying tin-substituted plating on it, and applying a thin coat of tin plated layer 4 which is softer then aluminum metal 2. The slide face 11 is liable to deform. When the fluidity is increased and the crank shaft B rotates and comes into contact with the slide face 11, the slide face 11 fits into the crank shaft B. As a result, contact with the crank shaft B becomes uniform, and contact with one face only is prevented.

IPC: F03B11/00
Filed: 1982-05-24
Abstract: PURPOSE:To protect a main machine when a private power source is out of operation during the operation of a hydraulic machinery, by automatically changing-over the pipe line systems thereof so that water is taken up from a water supply source substituting a main water supply pump. CONSTITUTION:The temperature of coolers is raised when a private power source is out of operation during the operation of a hydraulic machinery, thereby air is trapped in a casing 3. At this stage, on condition of the deenergization of the private power source, an automatic valve 19 in a water supply pipe 18 disposed between an iron pipe 6 and a water supply pipe 18, is opened, but an automatic valve 20 on the outlet side of a main water supply pump 8 is closed, so that water from the iron pipe 6 is fed to the coolers and the casing 3. Thereby, a temperature rise of the coolers and as well air trap in the casing may be prevented, and therefore, the main machine may be protected.

Title: Method for controlling injection speed of injection molder and apparatus thereof
Inventor: ARIE HAJIME
IPC: B29C45/77
Filed: 1990-03-31
Abstract: PURPOSE:Tc rapidly and highly accurately follow up injection speed to set speed and consequently obtain good and even quality molded item by a method wherein a plurality of groups of PID control constants used for PID processing are set in advance so as to correspond to molding conditions in order to select PID control constants corresponding to the changed molding conditions from the set groups of PID control constants at every change of molding conditions. CONSTITUTION:When the change of the viscosity of molding resin material from standard viscosity to low viscosity is intended, the set speed in a speed setter 10 is not changed and the PID control constants in a control operator 13 are changed to PID control constants corresponding to low viscosity molding resin material. The change is performed by operating a changing-over switch 182 so as to selectively change over control constants by a change over circuit 181 from among the first-Nth control constant setter 171-17n to the control constants corresponding to low viscosity molding resin material. Accordingly, when set speed is set as speed pattern, overshoot, undershoot and the like do not occur, resulting in allowing to control so as to follow up the set speed highly accurately.

Filed: 1984-04-27
Abstract: PURPOSE:To prevent the occurrence of vibrations and noises in a rotary pump, by interposing an elastic body between a housing forming externals of the pump and a cam ring receiving a pressure variation to be produced with rotation in a rotor. CONSTITUTION:When a rotor 3 gets rotating, each plunger 4 reciprocates inside a cylinder hole 3a, and a pump operating chamber is therefore repeats volumetric variations. And, a hydraulic fluid is pumped into the pump operating chamber by way of a piston 2, a suction passage 2c and a notch 2b, while this hydraulic fluid is discharged out of a pump by way of a notch 2a and a discharge passage 2d. In this case, an annular elastic body 6 is installed on the circumference of a cam ring 5 where the tip of each plunger 4 touches. Likewise, an inner ring 7, a roller body 8 and an outer ring 9 are disposed in order in an outer circumference of the elastic body 6. And, vibrations and noises produced out of space between the cam ring 5 and the plunger 4 or the like and transmitted to a housing 1 are absorbed by the elastic body 6, thus they are checked.

Abstract: PURPOSE:To enable the folding and unfolding of the portion of an umbrella exposed to rain drops while a user's body staying indoors by folding and unfolding the portion from the upper part of a cylinder or a grip. CONSTITUTION:The portion of an umbrella exposed to rain drops is folded and unfolded from the upper end of a cylinder or a grip, and a frame supporting the cloth or chemical fiber of the aforesaid portion is made of shape memory alloy or spring steel. The aforesaid portion and the frame thereof are housed in the cylinder and grip, in such a way that the back of the portion and the frame are in contact with the inner surface of the cylinder and the grip. A support part for folding and unfolding the portion and frame are housed in the grip and cylinder, and slide up and down therein. As the portion exposed to rain drops is folded and unfolded at the tip of the grip or cylinder, the aforesaid portion can be folded and unfolded, while the tip of an umbrella is projected through a gap between indoor and outdoor spaces, and a person is staying indoors. Rain drops do not come out when the portion exposed to the rain drops is housed inside from the tip of the cylinder and grip. It follows, therefore, that there is no possibility of wetting clothes and another person, while rain drops stagnating in the cylinder and grip can be discharged simply by inverting the umbrella.

Abstract: PURPOSE:To always maintain stable and prescribed press-contacting force against a separating claw by providing a notch part being larger than the inside diameter of a shaft, on both sides of a bearing part. CONSTITUTION:A separating claw 20 has a bearing part 25 by which toner powder, etc., leaking from a cleaning device scarcely go into the inside diameter of a bearing fitted to a supporting shaft 11, by which a stable rotational motion can be executed against the supporting shaft 11 by small frictional resistance. That is, the bearing part 25 has sufficient length in the axial direction, and provided with a notch part 26 of suitable depth being a little larger than the inside diameter of a bearing fitted to the supporting shaft 11, on both side ends thereof. Accordingly, even if toner powder, etc., go into a notch part 26, the toner powder, etc., are accumulated only in its opening part and do not move to the inside diameter of the bearing, because a space made by the inner periphery of the notch part 26 and the outer periphery of the supporting shaft 11 is narrow. As a result, as for the device, the frictional resistance to the same turning is always applied to the bearing part 25, a separating action is executed exactly and a toner image on the peripheral surface of a photosensitive drum is secured, and also, the separation of a transfer materials can be executed.
