Title: Variable mirror
Inventor: KIMURA KOJI
IPC: G02B5/10
Filed: 1988-12-20
Abstract: PURPOSE:To prevent the change in shape by a change in temp. by combining piezoelectric elements 5 of a lamination type, etc., having a positive or negative coefft. of thermal expansion and supporting rods having or negative coefft. of thermal expansion to form plural pieces of variable length supporting members which hold the mirror. CONSTITUTION:The variable length supporting members 4i of the deformable mirror 3 are formed by combining the plezoelectric elements 5 which change the length of the above-mentioned members according to impressed voltages and have the positive or negative coefft. of thermal expansion and the supporting rods 6 which are connected to the piezoelectric elements and have the coefft. of thermal expansion in the direction opposite to the coefft. of thermal expansion of the piezoelectric elements. This combination is so formed that the expansion and contraction by the temp. change of the lamination type piezoelectric elements 5 and the expansion and contraction by the temp. change of the supporting rods 6 are negated with each other, by which the expansion and contraction by the temp. over the entire part of the variable length supporting members 4i are compensated and the good temp. compensation is obtd. by adequately selecting the ratio of the lengths of the piezoelectric elements 5 and the supporting rods 6. The change in curvature by the temp. change is obviated in this way.

IPC: G01N21/84
Filed: 1989-12-18
Abstract: PURPOSE:To obtain the inspecting device being free from an erroneous detection and having high reliability by providing adjacently a laser beam photodetector on an inlet of a rolling passage, so that a laser beam can be photodetected before an image of the laser beam which is photodetected is deformed or enlarged. CONSTITUTION:By a laser beam projector 11, a laser beam irradiates a rolling passage 5 extending from its outlet 4 to its inlet 3. The laser beam passes through an angle detector 12, is set to an irradiation angle corresponding to a rate of reduction in area of a material to be worked in the rolling passage 5, and goes into the rolling passage 5 from the outlet 4. At the time of passing through the rolling passage 5, the laser beam passes through between rolls of rolling stands 2 of each stage, while expanding at a prescribed angle. The laser beam which passes through the rolling passage 5 goes out of the inlet 3, and is photodetected by a laser beam photodetector 13 positioned adjacently in the outside of the inlet 3. In such a state, in the case a photodetecting level becomes higher than a normal level set in the beginning, by setting it as a new normal photodetecting level, the influence exerted on the photodetecting level by a fluctuation of the laser beam and a variation of a reflected state caused by a temperature rise of a rolling roll is compensated, and an inspection of high accuracy can be executed.

Title: Optical disk and for only reproduction manufacture thereof
Inventor: OKADA OSAMU
IPC: G11B7/24085
Filed: 1991-12-11
Abstract: PURPOSE:To expand the limit of high densification and simultaneously to improve reproducing signals in high density recording by making the phase difference of information pits that are adjacent in front and rear as (2N/3)pi (where N is an integer). CONSTITUTION:By modulating the strength of exposing laser, the pits different in depth by which the phase difference in (2N/3)pi is given are alternately formed. In this case, since the phase difference also exists between the adjacent pits 2, 3, separation ability is improved by making the reflected waves from the adjacent pits mutually interfere and cancell, and therefore the limit of high densification is expanded. Meanwhile, the shortest pit length or the length between the pits is shrunken 2/3 to 1/2, and the reproduced signals in the high density recording is improved.

Abstract: PURPOSE:To prevent noises and the breakage of a substance to be electrified by providing a circuit which corrects the variation of the potential of the substance to be electrified charged and a control means and connecting a grid electrode and a ground at the time of completing an electrifying action necessary for producing an image. CONSTITUTION:A timer 30 discharges the charges accumulated in itself during a copying action to a grid electrode 22, so that the surface potential of a photo sensitive drum 1 is corrected. At the time of completing the electrifying action necessary for producing the image, such as at the time of idly rotating the drum 1, the electrode 22 is switched from a connection wire 25a to a connection wire 25b by a switching circuit 41. Since the electrode 22 is directly grounded to the ground 26, the potential of the grid electrode 22 and the drum 1 is set about zero. Therefore, a large electrostatic force which is the cause of the noises and the breakage of the drum 1 is not generated between them at the time of completing the electrifying action. The switching action of the circuit 41 is controlled by a CPU 40.
