Title: Flush door in which warp can be corrected
Inventor: WATANABE TOSHIYUKI
IPC: E06B3/82
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To correct the warp of a door in which warp is generated because warp is easy to be generated in the woody flush door. SOLUTION: A wire 3 is tensed previously between the top rail and bottom rail of a core material at bilateral symmetrical positions centering around the thickness center of the flush door, and a tensile means pulling the wire 3 from the upper section or side face of the door is mounted previously. Internal stress generated on the surface and rear of the door is balanced by tensing the wire 3 stretched on the surface side near to the surface side as the projecting side by the tensile means when the door is warped, and the warp of the door is corrected. Accordingly, warp can be corrected without removing the door.

Title: Apparatus for positioning mask
Inventor: KATAMATA YOSHIYUKI
IPC: G03F9/00
Filed: 1995-03-14
Abstract: PURPOSE: To reduce mask positioning time by calculating the displacement of a standard point of each mark before a mask is moved to a position on an exposure stage and, in the case the mask is positioned approximately, moving the mask quickly to a position where the mark is detectable by using that calculated result. CONSTITUTION: Two pairs of CCD cameras 48A, 48B, 50A, 50B are provided at the positions on a reticle changer 14 different from the position on an exposure stage 12. Then, pre-alignment data are collected beforehand as to two reticles R's other than a reticle R being in use for a exposure. Thus, even if the reticles R's are exchanged by providing a reticle-exchanging arm mechanism, quick pre-alignment of the reticle on the exposure stage 12 is possible by using these pre-alignment data. Therefore, a trouble that the alignment on the exposure stage 12 performed by mark position detecting means becomes difficult as a result of the displacement upon the exchange can be eliminated.

Title: Treatment of alkanolamine aqueous solution
Inventor: TSUJINO TOSHIO
IPC: C10K1/14
Filed: 1978-07-07
Abstract: PURPOSE: An alkanolamine aqueous solution containing thermally stable salts that form when industrial gases are treated with an alkanolamine aqueous solution is treated with an ion exchange resin to decompose the salts, thus regenerating alkanolamine.

Title: Resonance measuring instrument
Inventor: UESUREI HEIZU HEIWAADO
IPC: G01R27/28
Filed: 1987-04-02
Abstract: PURPOSE:To remotely find the resonance frequency of a resonance circuit with high accuracy by exciting a bridge circuit by an RF signal source frequency is variable and coupling it with the resonance circuit to the measured. CONSTITUTION:The bridge circuit 10 is coupled with the circuit 28 to be measured in such an unbalanced state that an inductor 16 is closer than an inductor 14. Consequently, the circuit 28 absorbs energy from the inductor 16 and the energy loss from the inductor 16 to the circuit 28 is modeled as effective loss resistance serial to the inductor. This effective loss resistance makes the bridge 10 unbalanced to cause some output from a detector 22 connected to an output port 24 to be read. The energy absorption by the circuit 28 becomes maximum when the frequency of the RF signal source 20 tunes to the resonance frequency of the circuit 28. The unbalance of the bridge 10 becomes maximum at this point of time. The resonance frequency of the circuit 28 is therefore determined at the point where the signal amplitude of the output port 24 is maximum by varying the frequency of the signal source 20 which is excited.

Title: Reproducing device for disk-like recording medium
Inventor: OKAMURA YUTAKA
IPC: G11B21/10
Filed: 1989-03-31
Abstract: PURPOSE:To ease the sharpness of the replacing drive of a reading means in the radius direction of a recording medium due to a driving means by reducing the level of a deviation signal inputted to the driving means in accordance with a signal output corresponding to a period up to the drop of the deviation signal to the 2nd reference level after exceeding the 1st reference level. CONSTITUTION:The reading means 15 outputs a deviation signal corresponding to a deviation value between its reference reading position and a reading position from which the recoding contents of the recording medium are read out. A driving means 18 starts its operation when the deviation signal exceeds the 1st reference signal and stops the operation at the time of dropping the deviation signal to the 2nd reference level to replace the reading means 15 in the radius direction of the recording medium 12. The reduction of the deviation signal level is increased by a signal conversion means in accordance with the shortening of the period detected by a detecting means and the driving means 18 is driven by a deviation signal whose signal level is reduced from that of the original deviation signal between the 1st and 2nd reference levels. Consequently, the sharp replacing drive of the reading means can be eased.

Abstract: PROBLEM TO BE SOLVED: To provide an air film molding which satisfies the suppression of the oscillation of a lighting fixture within a film structural body, the feasibility of obtaining a desired illumination-like design in spite of inclination of the film structural body, the easy foldability of the film structural body and the structure not to occupy a place for housing. SOLUTION: Both ends of first and second ropes 5a, 5b are mounted respectively at the inner top and bottom of the bag-shaped film structural body 2 and third, fourth ropes 5c, 5d are mounted at one end to the middle of these first, second ropes 5a, 5b. These third, fourth ropes 5c, 5d are respectively mounted at the other ends to the lighting fixture 4. When the film structural body 2 is three-dimensionally molded by an air pressure, the third, fourth ropes 5d, 5d are pulled by the expansion of the film structural body 2 and the lighting fixture 4 is pulled and held. Since the lighting fixture 4 is pulled and held by the third, fourth ropes 5a, 5c, the oscillation of the lighting fixture 4 within the film structural body 2 is suppressed even if the film structural body 2 oscillates. Even if the film structural body 2 inclines, the lighting fixture 4 exists in the designed position.  Further, the ropes 5 are soft and, therefore, the film structural body 2 is easily foldable and does not occupy the place for housing.
