Title: Non-contact seal device
Inventor: GOTO TETSUO
IPC: F16J15/44
Filed: 1992-06-10
Abstract: PURPOSE:To provide a non-contact seal device of which seal clearance is automatically adjusted so as to hold a desired clearance. CONSTITUTION:An introducing port 12 opened in the seal clerance A is communicated to the differential pressure chamber 18, of an actuator 15, and the differential pressure chamber 187 is communicated to a low pressure chamber 3 through the purge hole of small diameter of an orifice plate 21. When the seal clearance A is increased, the pressure in the differential pressure chamber 181 is raised so as to advance a seal ring 7, and when the seal clearance A is excessively reduced, the pressure in the differential pressure chamber 181 is reduced so as to retreat the seal ring, and hence the constant seal clearance A can be maintained.

IPC: G11B5/596
Filed: 1986-06-30
Abstract: PURPOSE:To shorten servo seek time and to expand a data area by setting a servo track in a specific position. CONSTITUTION:A 1st servo track group ST grouping four tracks is formed in the center of the data zone D of a magnetic disk 1, and 2nd servo tracks ST0 and ST1 are formed on the outer and inner peripheries, respectively.

Title: Surface treatment of optical waveguide
Inventor: KODERA KOUHEI
IPC: G02B6/00
Filed: 1982-08-31
Abstract: PURPOSE:To reduce the transmission loss occuring in the ruggedness, flaw on the surface and the internal stress owing to the molding distorsion of an optical waveguide obtd. by molding of a thermoplastic resin by including a stage for subjecting said optical waveguide to a heat treatment by bringing the same into contact with the vapor of a solvent which dissolve or swells said resin. CONSTITUTION:An optical waveguide obtd. by molding of polymethyl methacrylate, polycarbonate, etc. is brought into contact with the vapor of an org. solvent which dissolved or swells the respective resins in order to decrease the guide loss of light occuring in the surface characteristics such as the ruggedness, flaw or the like on the surface of said waveguide and the internal stress owing to the molding distorsion thereof. The waveguide injection molded from, for example, polymethyl methacrylate is left standing for 2 hours at 70 deg.C under reduced pressure of 2mm.Hg after standing for 3 minutes in the vapor of ethyl acetate kept at 77 deg.C under atm. pressure. A clad of a silicone resin is then provided on the surface whereby the optical waveguide is completed. The infiltration of the vapor down to the inside and the consequent deformation, etc. are obviated by such temp. time and drying under reduced pressure, and the flaw on the surface and internal stress are removed. The guide loss is thus decreased.

Title: Bellows
Inventor: SUZUKI KAZUO
IPC: F16J3/04
Filed: 1980-10-31
Abstract: PURPOSE: To smoothly absorb the twist of a bellows, by setting the plane contain ing the crest edge of the bellows, so that the plane is oblique to the axis of the bellows.  
     CONSTITUTION: The plane containing the edge of each crest of a bellows 9 is oblique to its axis. Each crest of the bellow 9 is annularly closed along the circumference. When torsional stress is applied to the cylindrical body of the bellows 9, tensile and compressive stress is caused along the surface of the cylindrical body of the bellows in the direction of a spiral whose pitch is 2Dm where Dm denotes the mean diameter of the cross section of the cylindrical body. The plane containing the edge of each crest is made oblique to the axis so that the plane ext ends perpendicularly to the direction of the spiral. As a result the tensile and compressive stress in the direction of the spiral is always absorbed by the contraction between the crests of the bellow 9 which extend almost perpendicularly to the direction of the spiral.

Inventor: GAMO KEIJI
IPC: G01N30/46
Filed: 1986-06-27
Abstract: PURPOSE:To set eluting conditions suitable for a desired component independently, by switching columns while supplying a mobile phase suited to the elution of the desired component to a plurality of columns. CONSTITUTION:When feed pumps 4 and 11 are operated to inject a sample into a sample injection port 5, a sample flows into an analysis column 2 by a first mobile phase to hold a elutable component alone. When a second passage is formed by an changeover valve 9, a component not held by the first mobile phase flows into a second analysis column 9. The desired component shifted to the second analysis column 9 is eluted by a second mobile phase to be held by a second analysis column 9. This keeps the flow rate ratio between the first and second moving layers, which flow into a liquid mixing means 8 from a branch tube 7, constant even at the switching of these passages and causes the layers to be mixed thoroughly, thereby eliminating hourly variations in the background noise of a detector 12.

Abstract: PURPOSE:To attain the accurate detection of original size without being influenced due to the state of an original image by executing the detecting operation of the original size by a sensor on the way of closing an original press and then executing the detecting operation again in the closed state of the original press. CONSTITUTION:An output signal from an optical sensor 37 is kept at the low level until the original press 41 is almost completely closed and then turned to the high level.

After depressing a print key 45, an AND gate 46 is opened and a high level signal is outputted from the gate 46. Thereby, an output signal from an XOR gate 47 is held at the high level until timing T1, held at the low level from the timing T1 to timing T2 and then turned to the high level again after the timing T2, so that no existence of an original on a position corresponding to the optical sensor 37 can be identified.
