Title: Method and device for reaming tunnel
Inventor: YAMAMOTO YOSHINORI
IPC: E21D9/10
Filed: 1994-10-18
Abstract: PURPOSE: To enable miniaturization of a reaming device and reductions in construction period and in operating cost by supporting the reaming device against the shaft wall of an existing tunnel, and enlarging the shaft wall while moving a reaming head in its circumferential direction. CONSTITUTION: A reaming device 10 is placed on a rail 19 laid inside an existing tunnel T and is conveyed into the tunnel from a base 11, then a reaming head 15 is positioned on the inner surface of the pit mouth of the tunnel T, and a support leg 33 is made to abut to the shaft wall W by a hydraulic jack 32 and held in place. Next, as the reaming head 15 mounted on a movable member 13 is moved in the radial direction of the tunnel T by an actuator 14, the reaming head 15 is operated by a rotary drive mechanism 16 via a rotating member 12 to crush the overall periphery of the shaft wall W at a predetermined depth and to enlarge the existing tunnel T by excavating natural ground A constituting the outer surface of the tunnel.  After the enlarging operation at that position is completed, a locking mechanism 17 is unlocked, and the reaming device 10 is moved a predetermined distance to continue the enlarging operation. Muck generated by crushing and excavation is discharged from the opposite side of the existing tunnel T.

Title: Reversible heat-sensitive recording medium and manufacture thereof
Inventor: MUTO TSUTOMU
IPC: C08F220/30
Filed: 1990-09-21
Abstract: PURPOSE:To obtain a reversible heat-sensitive recording medium colored or decolored with no chemical change and having the memory property by using a polymer liquid crystal which is a copolymer of a nematic monomer and a cholesteric monomer and having the cholesteric liquid crystal phase. CONSTITUTION:A recording layer of a polymer liquid crystal is provided on a base to obtain a recording medium, the polymer liquid crystal is a copolymer copolymerized with monomers expressed by the general formula (A) and the general formula (B), and it is colored, decolored or discolored by the difference of the heating temperature. The composition ratio of a cholesteric monomer which is a chiral component is important for this polymer liquid crystal, the cholesteric spiral pitch is reduced as the chiral component is increased, and the selective reflection wavelength is reduced. For the image formation with the polymer liquid crystal, an image line section is guided to a cholesteric color by heat, and it is cooled to the glass transition point (Tg) or below, thus the cholesteric color is fixed. When the recording face is guided to the isotropic phase and cooled to Tg or below, it can be erased.

Title: Optical sensor
Inventor: FUKUHARA SATOSHI
IPC: G01B9/02
Filed: 1989-09-28
Abstract: PURPOSE:To take an accurately measurement immune to the mode hopping of a semiconductor laser and a noise of a photodetecting element by observing variation in the intensity of the transmitted light of an optical resonator and measuring the interval of appearance between two light pulses. CONSTITUTION:When a 1st light pulse is inputted to the photodetecting element 9, a gate signal outputted by a gate circuit 11 turns on to go up to an H level and a counter 12 begins to count clock pulses 13. Similarly, when a 2nd light pulse is inputted to the element 9, the gate signal turns off and the counter 12 finishes counting the pulses 13. Variation in the counted value of the pulses 13 indicates variation in the frequency interval of the optical resonator and displacement is measured from it. Thus, the variation in the intensity of the transmitted light of the optical resonator is observed to measure the interval of appearance between the two light pulses, so even if the semiconductor laser 1 has mode hopping, the interval between the two light pulses is measured after the mode hopping to accurately measure the displacement of an object.

Title: Oil-cooled type rotary compressor
Inventor: KOJIMA YUKIHIRO
IPC: F04C29/02
Filed: 1994-10-19
Abstract: PURPOSE: To prevent the occurrence of an impossibility for oil to be fed to a compressor body due to breakage of a pilot pressure introduction pipe by communicating an air control valve to the delivery chamber of the compression body and operating the air control valve by means of the delivery pressure of the compressor body. CONSTITUTION: Even when, during operation, a pilot pressure introduction pipe 10 is ruptured, during operation of a compressor body 2, an air control valve 12 maintains a closing state (the side A) by means of a delivery pressure from the delivery chamber 21 of the compressor body 2, whereby a pilot pressure is not transmitted from the pilot pressure introduction pipe 10 to an oil check valve 9. Thus, with a valve body opened, lubrication oil is continuously fed in the compression operation space 2A of the compressor body 2. Meanwhile, when a line 13 is broken, the air control valve 12 is switched to a port on the side B, the oil check valve 9 is closed by the pressure of a receiver tank 4 through an air chamber 11 to stop the feed of oil. However, lubrication oil is fed to a bearing part through a branch pipe 14 by an oil pump 15.

Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To easily discriminate a state of a station by conducting information processing based on magnification information inputted by an input means when the magnification included in a registered parameter group is not set automatically. SOLUTION: In order to designate a magnification in X, Y directions in a display state 9-i, an under bar of a magnification display section in the X direction is blinked. When a ten-key is used to input a magnification, the state transits to a display state 9-i, and to designate a magnification in the Y direction, the under bar of a magnification display section in the Y direction blinks. Similarly, when the magnification is inputted, the state transits to a display state 9-k. When the magnification is desired to be changed, a display state 9-n or 9-j is restored by depressing a corresponding key like 9-1, 9-m. When a key SK corresponding to OK is depressed in the display state 9-k, the state restores to a display state 9-p and the designation of magnification is finished.  When a key SK6 corresponding to CANC is depressed in display states 9-i, 9-j, 9-k, 9-n. the state reaches the display state 9-1 before setting of the magnification.
