Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To manufacture a small-diameter and small-curvature lens and a lens forming metal mold surface with high accuracy and at a high grade by controlling a flow of slurry jetted from a pore provided in the tip of a polishing tool to a fixed flow and moving the polishing tool near by the surface of an object to be polished at a fixed stay time. SOLUTION: At the time of jetting slurry 4 obtained by previously mxing water 8 and fine abrasive grains 7 at a fixed ratio forcibly from a pore 3 to be strongly applied to the surface 5 to be polished, the fine abrasive grains 7 cause the polishing action to the surface of the surface 5 to be polished. An object 1 to be polished and a polishing tool are controlled to be relatively rotated or reciprocated so that the stay time of the polishing tool is controlled to make a pore 3 stay uniformly to the surface 5 to be polished. The liquid feed pressure and the flow of the slurry 4 are controlled so that the polishing tool is a little floated from the surface 5 to be polished to attain satisfactory polishing action of the fine abrasin grains 7.  At this time, it is necessary to prevent such a movement locus control that a specified part of the pore 3 polihses a specified part of the surface 5 to be polished.

Title: Thermosyphon type generator
Inventor: SHIINA KOUJI
IPC: F01K25/00
Filed: 1983-07-08
Abstract: PURPOSE:To aim at reduction in an auxiliary power ratio and the miniaturization and capacity improvement of a regenerator, by setting up several units of circulating jet pumps inside an evaporating part of a vertical thermosyphon type enclosed vessel, while installing a turbine and a generator outside the said vessel. CONSTITUTION:One heat pipe vessel 4 is divided into three parts, i.e., the lower part is set down to an evaporating part 4a, the intermediate plate to an insulating part 4b and the upper part to a condensing part 4c, respectively, while a generator 18 is installed in the upper part of the vessel 4 via a small-sized radial turbine 7 and a transfer mechanism 8. When the evaporating part 4a is heated with a heater A, a steam ascending current C is produced whereby working medium steam is made into adiabatic expansion inside the turbine 7, rotating the generator 18, and thus outputted. Afterward, the steam is condensed into liquefaction by radiation B, forming a descending current D, and the same action takes place again. A jet pump 14c forcedly circulates a low boiling point medium. Thus, an auxiliary power ratio in a pump is reducible and what is more, the miniaturization and capacity improvement of a regenerator both are well promoted.

Title: Particle flux shielding device
Inventor: NAKAJIMA SADAO
IPC: H01J37/09
Filed: 1988-05-20
Abstract: PURPOSE:To reduce the radiation amount of particle flux per unit time in the same radiation area and to prevent the temperature rise owing to the Joule heat by rotating a shield or moving it straightly in the direction crossing square to the particle flux. CONSTITUTION:A shield plate, which was fixed and fell when a substrate 3 was irradiated, conventionally, is rotated at a constant speed, and when the substrate 3 is irradiated, it is moved in the direction crossing square to the incident direction of the particle flux 5. As a result, while the area radiated by the particle flux 5 in the conventional device was aXb, the area of the particle flux radiation can be made pi(2r+a)/b times compared to the conventional composition. Accordingly, the power intensity on the particle flux shielding device to the same section form of the particle flux 5 can be reduced to b/pi (2r+a). Consequently, the temperature rise of a rotary plate 10 owing to the Joule heat can be suppressed, and the fusion can be prevented.

Title: Preparation of foamable polyethylene resin
Inventor: UEI TSUGI
IPC: C08J9/16
Filed: 1986-05-30
Abstract: PURPOSE:To obtain a foamable polyethylene resin having good impact resistance, by adding a vinyl arom. monomer contg. an org. peroxide in an aq. suspension of a polyethylene resin and passing the mixture through a high-temp. region. CONSTITUTION:To prepare polyethylene foamable resin particles, a suspension is prepd. by dispersing a polyethylene resin functioning as nuclei with a dispersing agent in an aq. medium. A vinyl arom. monomer contg. a small amt. of an org. peroxide is thereafter added thereinto and absorbed thereby and the mixture is passed through a high temp. region to obtain the aimed resin. The ratio of the above-described polyethylene resin to the vinyl arom. monomer is usually such that the former is 90-50wt% and the latter is 10-50wt%. It is preferable that the temp. of the high-temp. region is + or -30 deg.C of the m.p. of the polyethylene as the nuclei. The resin becomes spherical after passing through this high-temp. region. When bead foaming of the resin thus obtained to which a foaming agent is added is carried out, the shapes of the beads become spherical and the impact resistance of the foam is remarkably improved.

Title: Speed controller for ac motor
Inventor: SAWADA NAOMASA
IPC: H02P21/18
Filed: 1987-05-22
Abstract: PURPOSE:To correct delay of control even upon abrupt variation of load, by providing a variation amount setter and predicting deviation between a reference current and an actual current. CONSTITUTION:A variation amount setter 22 predicts occurrence of deviation between d.q co-ordinates of reference current and d.q co-ordinates of actual current when variation amount of the reference current increases. The variation amount setter 22 sets the output of a current variation detector 21 at a reference level, and when the output from the current variation detector 21 exceeds over the reference level, a position signal converted through an integrator 20 is outputted. Then the output is added to the output from d-axis deviation operating unit 23 and multiplied proportionally through a proportion unit 24. Output from the proportion unit 24 is fed to d-axis compensator 25, and delay of control is corrected by matching d-axis control position with d-axis position on an induction motor.

Abstract: PURPOSE:To detect a plurality of moving data of an object to-be-measured, for instance, data of a linear motion and a rotation simultaneously by installing a plurality of diffraction gratings to the object. CONSTITUTION:Two reflection-type diffraction gratings 5a, 5b are set for the object. A luminous flux from a light source 1 is shaped by a collimator lens 2 and then separated by a polarization beam splitter 3a to polarization lights LS, LP. The beam splitter 3a is arranged 45 to an optical axis of a plane of polarization. When the two diffraction gratings 5a, 5b shift in a direction of an arrow A (linear motion), a photodetector 9a detects the movement of interference fringes consequent to the movement of the gratings 5a, 5b. Data of the movement of the gratings 5a, 5b, namely, data of the movement of a shaft 10 are obtained by an operating means from a signal from the photodetector 9a. When tone gratings 5a, 5b rotate in a direction of an arrow B, a photodetector 9b detects the movement, of the interference fringes, and accordingly data of the rotation within a plane of each grating 5a, 5b are detected.
