Title: Rotary compressor
Inventor: SAKAMAKI HIROSHI
IPC: F04C18/348
Filed: 1988-07-15
Abstract: PURPOSE:To prevent a pneumatic bearing from scuffing by getting air to flow into a pneumatic bearing chamber between a rotary sleeve and a center housing via an inflow port of the center housing and providing an air containing channel on a center housing surface with which the rotary sleeve comes into contact. CONSTITUTION:A rotary sleeve 30 is mounted in a center housing 22, and a thin film-like pneumatic bearing chamber 40 is made to exist between the both. The rotary sleeve 30 has tendency to touch to the center housing at the contact zone on delivery side of inner periphery surface of the same, but as there is an air containing channel 722 on final end 52 of the contact zone, the bearing load ability of the pneumatic bearing chamber 40 is made to increase due to air absorbed from an inflow port 71. Therefore, apprehension for generation of skuffing vanishes.

Filed: 1988-07-15
Abstract: PURPOSE:To form a film having desired characteristics by first dyeing a dyeable film by a dye which is hardly dyeable to the dyeable film, then dyeing the same by a dye which is easily dyeable thereto. CONSTITUTION:The dyeable film 2 is formed on a glass substrate 1. UV rays are exposed to the dyeable film 2 through a negative photomask 3 on which a filter forming region is drawn. Since the exposed part of the dyeable photosensitive film 2 is cured, this dyeable photosensitive film 2 is developed with water to remove the unexposed part. A pattern 4 to be dyed is then dyed to cyan by a cyan dye which is the hardly dyeable dye and the film is dyed by a yellow dye upon ending of said dyeing, by which the pattern 4 to be dyed can be dyed to the desired green. The film is subjected to a reserve printing treatment by immersing the same in an aq. tannic acid soln. and an aq. tartar emetic soln. to form a dyed pattern 5. The color filter of a 1st color is thus obtd. The film is subjected to the dyeing treatment by the dye which is relatively hardly dyeable to the dyeable film among the dyes and thereafter the dyeing by the dye which is easily dyeable to said film is executed, by which the color filter having the desired characteristics is easily obtd.

Title: Method for driving liquid crystal display device
Inventor: MATSUEDA YOJIRO
IPC: G02F1/133
Filed: 1991-07-16
Abstract: PURPOSE:To obtain the driving method by which the influence owing to a shift voltage is minimized, a flicker, seizure and a residual image are eliminated, and a liquid crystal is scarcely deteriorated by optimizing the driving method for the liquid crystal display device. CONSTITUTION:A first driving method suppresses a difference of shift voltages  V between fields by superposing a range of a potential difference between an image input signal potential 1 applied to a signal line in a first field and a scanning signal potential 2 at the time of selection applied to a scanning line, to the range of this potential difference in a second field at least in a part thereof. A second driving method suppresses a selection pulse to the absolute minimum amplitude in order to minimize the influence of a shift voltage, since the shift voltage  V generally depends on a voltage of the selection pulse of the scanning line. A third driving method compresses a signal of a low potential side in the case of writing an image signal by positive polarity, expands a high potential side in the case of writing by negative polarity, and modulates the image signal so that a potential range of the negative polarity side becomes larger than a voltage range of the positive polarity.

Abstract: PURPOSE:To obtain the steel pipe which has sufficient high-temp. creep strength and workability, a narrow fluctuation range and uniform grains by subjecting the steel pipe obtd. by hot pipe making at a high reduction ratio then to an intermediate heat treatment at a specific high temp. and specifying the final reduction ratio. CONSTITUTION:The blank pipe of the title steel obtd. by hot pipe making is cold worked at the high reduction ratio of >=50% and after this pipe is heated to 1240-1280 deg.C and is cooled, the pipe is further subjected to the cold working at 20-40% reduction ratio then to the final solid soln. treatment at 1100-1200 deg.C. The steel pipe is affected by the previous history and the control of the crystal grain size is difficult if the reduction ratio at the 1st working is <50%. The high-temp. heat treatment after the 1st working is required to be executed at >=1240 deg.C in order to control the crystal grain size before the 2nd working to the target grain size. Further, the strain impartation enough to provide the driving force for recrystallization cannot be executed in the subsequent heat treatment if the reduction ratio at the time of the 2nd working is <20%. The fine crystal grains are formed and the control of the crystal grain size is difficult when the recrystallization executed by the subsequent heat treatment if the reduction ratio is over 40%.

Filed: 1980-12-15
Abstract: PURPOSE:To prevent abnormal data from being written by detecting a drop in a rectified power source output and setting a writing voltage in an unwritten state when it is detected. CONSTITUTION:If a power failure occures during the operation of a disk 1, this power failure is detected by a power-failure detecting circuit 18 as a drop in the output voltage DC2 of a rectifier 17 to generate a power-failure detection signal ES. This detection signal ES energized a relay circuit 19 to change a transfer contact 20 from a write power source 15 side over to an earth side, so that a write power source voltage WBV applied to a write control circuit 11 is held at the earth potential instantaneously. Thus an unwritten state is set to prevent an abnormal write signal from being supplied to a head 3 even if the write control circuit 11 malfunctions owing to a drop in logical driving voltage LMV. Thus, the abnormal data is prevented from being written.

Title: Air spring
Inventor: UCHIDA KIMIO
IPC: F16F9/05
Filed: 1980-12-15
Abstract: PURPOSE:To enable to provide an effective vibration proof support against horizontal vibrations without generating any rolling by a method wherein the ratio of the volume of an air chamber to the pressure-receiving area of the chamber is set to be 1 (unity) or below. CONSTITUTION:The ratio of the volume Vs to the pressure-receiving area Ac of the air chamber 5 formed of an upper metallic member 1, a lower metallic member 2 and a rubber plate is set to be 1 (unity) or below. In practice, the condition of Vs/Ac<=1 may be realized by setting the height H of the air chamber 5 to be extremely low. A practical range of the ratio Vs/Ac is preferably 0.2- 0.3. By setting the value of Vs/Ac to be not larger than 1, the vertical spring constant Hv becomes about 10 or more times of the horizontal spring constant Hs. Accordingly, when a device generating horizontal vibrational forces is supported by this air spring, no rolling occurs and the horizontal vibration can be prevented effectively.
