Abstract: A clamp apparatus converts the rectilinear motion of a cylinder into the rotary motion by means of a toggle mechanism to clamp a workpiece by using an arm. A release projection is covered with a top cover made of metal, preferably with a top cover coated with a material excellent in smoothness. When the arm is going to be unlocked by using the release projection, a tongue of the top cover is lifted upwardly to open the top cover, and the release projection is pushed and moved downwardly.

Abstract: An impact-type rotary fining, homogenizing and emulsifying device is constituted by a casing body disposed on a base, a feed port and a discharge port disposed in the casing body, and a power shaft disposed inside of the casing body. The power shaft is equipped with rotary impellers in such a manner that the rotary impellers are disposed on the power shaft and include a first rotary impeller rotated in a positive direction and a second rotary impeller rotated in negative direction. A power shaft portion is located in the feed port and is equipped with a feed impeller. A valuable advantage is obtained in that its new and distinct structure and innovative design enable the device to heighten the impact velocity applied to treated materials many fold, without raising the rotating speed of the impellers. Functions of fining, homogenizing and emulsifying are improved, while effectively enhancing the overall performance of the apparatus, within the motor's allowable rotational speed.

Abstract: A communication chamber defined in a body is supplied with a fluid under pressure through a pipe connected to a supply port defined in the body. The fluid under pressure is ejected from the communication chamber through fluid ejection members, which are made of a porous material and mounted on an end face of the body by a plate, toward a workpiece. The workpiece is levitated upwardly and held airborne by the fluid under pressure that is ejected toward the workpiece and the fluid under pressure that flows between the workpiece and the plate.

A second diaphragm is provided at an upper position spaced by a predetermined distance from the first diaphragm so that the second diaphragm is substantially in parallel to the first diaphragm. When the fluid permeates through the first diaphragm, the fluid is blocked by the second diaphragm. A buffering spring member is installed in a space which is defined between the second diaphragm and a first skirt section formed to extend radially outwardly from a main body section of the first diaphragm, and the pressing force exerted on the first diaphragm and the second diaphragm is reduced thereby.

Abstract: Seal sections, which support first and second piston rods, are provided on inner circumferential surfaces of first and second cover members of a cylinder mechanism. A lubricant is supplied via supply passages and oil supply ports to first oil-retaining members, which are installed in installation grooves provided in the seal sections. The lubricant, which has characteristics different from those of an operation oil used for driving a piston of the cylinder mechanism, is retained by the first oil-retaining members. Further, the lubricant is supplied to clearances formed between the first and second cover members and the first and second piston rods, thereby forming an oil film.

Abstract: A vibration sensor mounted on a tree on the earth outputs a signal voltage corresponding to a sound from the earth. The signal voltage is continuously measured by a sound observing device and read into a data processing device. The data processing device has a forecasting unit which performs a long-term weather forecasting process based on the value of the signal voltage, i.e., a sound pressure level representing the magnitude of the sound pressure of the sound from the earth. Specifically, the forecasting unit forecasts long-term weather conditions such as warm and cold climates related to high and low temperatures three and six months after the measurement of the sound from the earth, based on changes in the sound pressure level of the measured sound.

Abstract: A float-type flowmeter measures the rate of a fluid flowing upwardly through a tube based on the position of a float movably disposed in the tube and including a magnetic material. A coil is wound around the tube such that the intervals gradually decrease in an axial direction. The coil is excited by an alternating current supplied from an inductance change detector. The inductance change detector detects a change in the inductance of the coil which is caused when the float moves in the axial direction, and generates a voltage. A voltage-to-position (flow rate) converter determines a flow rate from the voltage corresponding to the position of the float.
