Title: Method of forming diffraction grating
Inventor: KUNITSUGU YASUHIRO
IPC: G02B5/18
Filed: 1991-06-24
Abstract: PURPOSE:To improve uniformity in the surface of a diffraction grating, by a method wherein the film thickness distribution of resist is made approximate to the light intensity distribution of interference fringes of two luminous fluxes with which resist is irradiated, and the resist film thickness in a region where the light intensity is lowered from the substrate center toward the periphery is made small. CONSTITUTION:A substrate 1 is coated with resist 2 so as to have the film thickness distribution wherein the film thickness is reduced in accordance with the distance further from the center. Single wavelength laser light is divided into two luminous fluxes after being expanded, and the resist 2 is exposed to interference light 4 of two luminous fluxes wherein interference fringes are formed. At this time, the light intensity 3 of interference fringes of the interference light 4 of two luminous fluxes is reduced as Gaussian distribution in accordance with distance further from the center of time substrate 1 toward the end portions. On account of film thickness distribution resist like light, the thick film part is irradiated with the interference light of large intensity, and the thin film part is irradiated with the interference light of small intensity. Thereby the degree of exposure of the resist is averaged all over the resist, and a diffraction grating excellent in surface uniformity can be formed.

Abstract: PROBLEM TO BE SOLVED: To adjust an applied magnetic field in accordance with the magnetized state of an adjacent track and to prevent the occurrence of fluctuation in a recording mark shape due to the effect of a leakage magnetic field by before- hand correcting the part of the leakage magnetic field from there when the magnetization of the adjacent track faces to one direction and producing the magnetic field attaching an offset with a head. SOLUTION: When a leakage magnetic field from an adjacent track is large, the size of the leakage magnetic field is measured beforehand and an offset 5 correcting the size of the leakage magnetic field from the adjacent track is provided on the applied magnetic field of a head according to its measured value. A magnetic sensor consisting of an MR head, a Hall element, etc., is equipped prior to a laser beam and the applied magnetic field head for a disk to be fed back to the offset 5 according to the size of the magnetic field detected there in recording. Thus, a mark without reflecting the effect of the leakage magnetic field from the adjacent track is recorded.

Filed: 1995-07-19
Abstract: PROBLEM TO BE SOLVED: To cool the inside of a device main body with air through simple and inexpensive constitution without being affected by external environment by forming an air passage partitioned with a device main body housing wall surface. SOLUTION: A casing 10 for the air flow passage is fitted to the external surface of a device main body housing substantially in contact. This casing 10 is open on both its end sides, i.e., facing the device main body housing and fans 11 and 12 which generate an air flow are installed in those open parts.

IPC: G01N29/00
Filed: 1993-07-26
Abstract: PURPOSE:To discriminate a liquid type rapidly and clearly at a site for manufacturing a drink, especially liquors or fruit juice drinks. CONSTITUTION:The type of a liquid is identified according to the ultrasonic propagation rate and electrical conductance inside the target liquid. Considering a coordinate system where both indexes are on a rectangular coordinate, the liquid identified by both indexes is displayed as a dot in the coordinate system. When both indexes obtained for different types of liquids are plotted on the coordinate system, the different liquid types occupies a specific position inside the coordinate system and do not overlap at all. For example, beers A-D with different production conditions occupy specific positions inside the coordinate system, thus discriminating the liquid types.

Abstract: PROBLEM TO BE SOLVED: To flexibly operate a system in accordance with various conditions by simultaneously executing a processing for generating data of a tool track and a processing for driving a tool and cutting/working a desired cutting material into the shape of a work target in parallel. SOLUTION: When an operator instructs cutting work on generated die shape data, an operation processing part 7 receives the condition of cutting work by a tool track data generation routine 7B and sequentially generates tool track data.
