Title: Method for predicting photoresist pattern
Inventor: TANABE YASUYOSHI
IPC: G03F1/68
Filed: 1995-02-27
Abstract: PURPOSE: To simply and highly accurately predict a photoresist pattern by calculating a position of light intensity corresponding to a threshold from a light intensity distribution of a designed pattern, and predicting an outline of the photoresist pattern on photoresist based on position information. CONSTITUTION: When an optical image is to be formed on a resist surface using a photomask pattern 11 to be a reference pattern, light intensity 15 on a resist surface at a position 19 distant by a predetermined distance (d) from an outline 18 of the photomask pattern 11 is calculated from a light intensity distribution 13, and the value is specified as a reference value. With a crossing point of the reference value of light intensity 15 and a light intensity distribution 14 due to a photomask pattern 12 of a designed pattern as a reference position, a position 111 close to an outline of the photomask pattern 12 distant from the reference position 110 by the distance (d) is made to be a predicted position of a resist pattern after development, and a length of a segment connecting the predicted positions 111,111, is predicted as a line width 17 of the photomask pattern 12.

Abstract: PROBLEM TO BE SOLVED: To eliminate independent excessive parts and hit much amount of cold air against water in an ice making pan unit to shorten a time necessary for ice making by a method wherein the ice making pan is provided with ribs for hitting the cold air against water in recessed parts at positions on the rims, on parts between a plurality of side rims or positions opposed to the side rims of the ice making pan. SOLUTION: A flexible ice making pan 13, having a plurality of recessed parts 12 and made of a resin, is provided pivotally at a position opposed to an air discharging port 11 provided on a partitioning body 7 while ice making pan side wall ribs 18 are provided on the rim parts 16 of internal horizontal walls side 15. Cold air, cooled by a cooler 5, flows out of the discharging port 11 to the upper part of the ice making pan 13 by a fan 6. The position of the fan 6 is at the center of a chamber and the flow of cold air becomes radial by the rotation of the fan 6 whereby the cold air flows on the inside horizontal wall sides 15 in the upper part of the ice making pan 13 to hit the side wall ribs 18 of the ice making pan and, therefore, most of the cold air cools water in the recessed parts 12. Accordingly, ice making can be effected within a short period of time.

Abstract: PURPOSE:To prevent disconnection by using a low resistor buried to the surface of a semi-insulating substrate in place of the metallic wiring of the first layer, forming no difference in stages to the surface and disposing the second layer to the flat surface while interposing an insulating film. CONSTITUTION:An N<+> GaAs layer 20 is shaped to the semi-insulating substrate 11 through ion implantation and annealing. The layer 20 is 10mum long and 5mum wide. AuGe alloys 23, 24 are formed, a TiAu alloy film 22 with 0.5mum thickness is shaped, and ohmic connection is formed. The second wiring layer 21 is shaped through the SiO2 13 with 0.5mum thickness. According to this constitution, the second wiring 21 is not disconnected because it is formed onto the flat surface. Wiring resistance by the N<+> layer 20 increases to some extent, but a time constant is reduced because load capacity is small in the practical GaAs IC, and the increase has hardly effect on the working speed of the IC.

Abstract: PURPOSE:To obtain a small-sized high-intensity illumination device by using a high-luminance discharge lamp for a light source in place of a conventional incandescent lamp, and illuminating it via an optical material with the characteristic cutting the ultraviolet rays of the radiation light from this lamp. CONSTITUTION:An optical material 3 is provided for cutting the ultraviolet rays until the radiation light from a high-luminance discharge lamp 1 is radiated to the environment, and thus the skin erythema effect and cornea injury effect can be prevented. The short-wavelength section in the visible region is also effectively cut, so that the sunburn action, light trap action, material damage/ deterioration action, and retina injury action can be suppressed nearly to the level of a conventional incandescent headlamp. The preset luminance of a light source is obtained at a low color temperature to suppress the glare, and the cutting characteristic on the short wavelength side is effectively made sharp. The attenuation of the light radiation at the long wavelength in the visible region is therefore small, and the efficient reduction of the light radiation in the visible region can be suppressed to the minimum.

Title: Expanded graphite sheet
Inventor: UEDA TAKAHISA
IPC: C01B31/04
Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To obtain an expanded graphite sheet that is provided with water- and moisture-absorptivity to greatly reduce its coefficient of friction and sliding resistance, and secures an excellent sealing performance, by setting a contact angle of at least one side of the expanded graphite base, consisting of expanded graphite particles pressed mutually to form a monolithic body, with water at a given level or lower. SOLUTION: This expanded graphite sheet allows water dropped thereon to be absorbed in a short time into the sheet, when it has a contact angle θwith water of 85 deg. or smaller. It is therefore possible for water to be absorbed easily into the sheet to realize a frictional condition close to boundary lubrication, so long as the sheet is operated under a condition containing a small quantity of water, thus reducing sliding resistance of the sheet, when it is used as a packing or sliding member. Moreover, the sheet working, e.g. as a sealing material, can absorb water which penetrates into its voids without leaking it, to increase sealing face pressure and stress conversion coefficient by swelling action of the absorbed water, allowing itself to exhibit an excellent sealing performance by a low clamping pressure.

Filed: 1978-04-05
Abstract: PURPOSE: To prevent heat-stress-caused rotor deformation by furnishing a communication steam line between a low-temperature steam line and a high-temperature steam line.  
     CONSTITUTION: A control mechanism is made up by placing a communication line 27 which extends to two points between a valve 13 and orifice 14 mounted in a low- temperature steam line 8 and a valve 15 and orifice 16 mounted in a high-temperature steam line 9. The valves 13, 15 whose opening are determined to give equal pressure at the contact points 18, 19 near a rated load permits no steam to run to a control orifice 17 of the communication steam line 27. On the other hand, at partial load of pressure, a pressure at the contact point 19 rises higher than that at the contact point 18 so that high-temperature steam runs in the communication steam line 27 from the contact point 19 to the contact point 18. This can keep approximately constant difference in temperature between a mixed steam line 10 and a high-temperature reheating steam line 7.
