Title: Method for resetting of digital micromirror device
Inventor: RICHIYAADO OBITSUDO GAARE
IPC: G02B26/08
Filed: 1995-03-06
Abstract: PURPOSE: To provide a new control method for digital micromirror device. CONSTITUTION: For this method for controlling a digital micromirror device 40 so as to decrease mechanical stress, to more prolong the service life of the device, to reduce the generation of positive bit reset and to improve the accuracy of pulse width modulation, a bias voltage 142 impressed to a mirror 50 for decreasing the stress of the device can be dropped after the mirror 50 is locked (latched). After the mirror has been driven to a desired position for preventing the change of the mirror at too early timing, an address electrode bias voltage 140 can be dropped. In order to guarantee the recovery of the mirror 50 to a neutral position in the case of reset, during a reset period 152, a mirror bias voltage 142 can be increased from a ground potential to the almost intermediate voltage of two address voltages. In order to decrease the storage operation of a hinge and to guarantee the rotation of the mirror 50 toward a proper address electrode, the mirror bias voltage 142 is gradually increrased, so that the mirror 50 can be rotated toward the proper address electrode.

Inventor: YAMADA YUSUKE
IPC: B24B5/18
Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To prevent the production of the scratch caused by the sliding of a blade and a cylindrical member by providing a blade that has a form having many contact points which axially contact a workpiece in a point contact state and whose peaks are round. SOLUTION: The contact surface of a blade 3 has many contact points, which axially contact with a workpiece 4 in a point contact state, that is, each contact point has a seal-cut shape. The workpiece 4 contacts with the blade 3 at the peaks of its seal-cut contact points to be supported by the blade 3. The radius of curvature of these peaks R must be within 0.2 to 2.0mm or if possible 0.5 to 0.8. Since the workpiece 4 is supported by the blade 3 in a point contact state, chips and abrasive grains are not piled between the workpiece 4 and blade 3, and smoothly flow to be discharged.

Title: Production of magnetic recording medium
Inventor: OOIWA TSUNEMI
IPC: G11B5/85
Filed: 1983-03-18
Abstract: PURPOSE:To obtain a magnetic recording medium having excellent uniformity in magnetic characteristics by using cooling drum which consists of a drum body formed of copper and is plated on the outside circumferential surface thereof with chromium or two layers of nickel and chromium, disposing such drum in a vacuum vessel and performing vacuum deposition or sputtering, etc. CONSTITUTION:A cooling drum 3 onsisting of a drum 31 which is formed of copper and on which a chrome plating layer 22 is formed by chrome plating is disposed in the central part of a vacuum vessel of a vacuum deposition device and a polyester base film 4 is so set on a take-up roll 6 that the film is moved along the circumferential side face of the drum 3 from a stock roll 5 and is taken up on the take-up roll. For example, a cobalt-nickel alloy 8 is set to a vapor source 7 for a ferromagnetic material. The inside of the vessel 1 is then evacuated to a vacuum by an evacuating system and the alloy 8 in the source 7 is heated by a thermion source 9 to perform vapor deposition, thereby forming the thin ferromagnetic metallic film layer consisting of the cobalt- nickel alloy on the film 4. There is thus virtually no temp. difference of the cooling drum between the stage when the vacuum deposition is started and the stage just prior to the end thereof and the fluctuation in coercive force is decreased, by which the uniformity in the magnetic characteristic of the resulted magnetic recording medium is improved.

CONSTITUTION:This catalyst is produced by carrying silver and/or silver oxide on an activated alumina while satisfying the following relations of the fine pore radius and fine pore volume measured by a nitrogen gas adsorption method: B is 30% or more of A and C is 15% of less of A: wherein A stands for the total value of the fine pore volume of the fine pores with 300Angstrom  or smaller fine pore diameter, B for the total value of fine pore volume of fine pores with 50Angstrom  or smaller fine pore diameter, and C for the total value of fine pore volume of fine pores with 100-300Angstrom  fine pore diameter. The catalyst and an exhaust gas is brought into contact with each other in the conditions of 10000h<-1> or higher space velocity of the exhaust gas passing through the catalytic layer and 400-550 deg.C temperature range at an inlet of the catalytic layer. Consequently, under an oxygen excessive atmosphere, the nitrogen oxides in an exhaust gas from an internal combustion engine of lean air-fuel ratio are reduced and cleaned even at high space velocity and high conversion efficiency.

CONSTITUTION:When a wafer 2 transferred to a transportation roll 34 is fed between guides 39, a position detecting mechanism 41 detects the wafer and projects pins 45 to the upper part of a roll 32 whereby the wafer is made to abut on the pins 45. Since the center of the wafer corresponds to the center of a circular arc 39a of each of the guides 39 at the position where the pins are projected, rough alignment of the wafer is completed at the time when it is made to abut on the pins. A chuck top 40 movable in three dimensions is raised to carry the wafer thereon and to held the same at an equal level to that of the guides 39. The circular arcs 39a of the guides 39 are made to abut on the peripheral edges of the wafer through a cylinder 42 of an adjusting mechanism 44 so that the center of the wafer 2 is aligned with the center of the chuck top 40 correctly. After that, the wafer 2 is held by suction and fixed by the chuck top 40 and the wafer 2 is fed to a spin coating apparatus, for example.

Abstract: PURPOSE:To make easy the color-coded painting on the surface of Al, etc. by segmenting the painting part of a base material consisting of Al or Al alloy and coating an org. paint to the segmented part then coating an inorg. paint over the entire surface of the base material. CONSTITUTION:The org. paint is first partially coated on the surface of a base plate 13 consisting of Al or Al alloy to form an org. paint film 21 and thereafter the inorg. paint contg. hydrous silica colloid is coated over the entire surface of the plate 13 to form an inorg. paint film 23 over the entire surface of the plate 13 in a painting method for Al or Al alloy. The film 21 and the film 23 have weak adhesive power to each other and therefore the part 23a covering the film 21 in the film 23 is easily stripped. The easy selective painting of the surface of the base material consisting of Al or Al alloy without masking is thus made possible.

Abstract: PURPOSE:To reduce the size and weight of the titled telescope without using a balance weight by installing a submirror with about 15 deg. inclination from the optical axis of reflected light and setting up a steady point in a body tube. CONSTITUTION:The fitting angle of the sub-mirror 5 is inclined by about 15 deg. from the optical axis and the reflected light by a main mirror 4 is refracted by about 30 deg. to shorten the body tube 3. An eyepiece part 6 is fitted to the body tube 30 3 with about 30 deg. inclination, an eye-piece lens 11 is arranged on an almost intermediate position of the body tube 3 and a frame 2 is set up so that the steady point P is arranged on a position near the eyepiece 11 in the body tube 3, so that the balance weight can be omitted and the telescope can be reduced at its size and weight and can be easily operated. Since the steady point P is set up in the body tube 3 of the telescope 1, the interval between the steady point P and the center B of the gravity of the telescope 1 is extremely narrowed as compared to an ordinary equatorial reflecting telescope and the weight torque of the telescope 1 acting on a right-ascension shaft 8 is reduced at least <=1/2.
