Abstract: PURPOSE:To easily and securely perform welding operation without any trouble by welding a weld zone while observing the weld zone by an optical system for observation like an endoscope. CONSTITUTION:A moving carriage 13 fitted with the insertion part 10 of the endoscope 9 and a laser probe 6 is guided in a buried pipe 1 and those insertion part 10 and laser probe 6 are positioned in the buried pipe 1. Then a controller 8 is operated to move forth and back the moving carriage 13 and also rotate a holder 35 around the optical axis, and thus the observation optical system and a lighting optical system on the tip of the insertion part 10 are shifted in position successively to observe the state of the internal surface of the buried pipe through an ocular part 12 while irradiating the internal surface of the buried pipe 1 with illumination light from the lighting optical system. The controller 8 is further operated to adjust the tip of the laser probe 6 to a broken part 2, thereby setting the irradiation direction of the laser light. Then a laser generating device 4 is put in operation to irradiate the broken part 2 with the laser light and this broken part 2 is welded from inside the buried pipe 1.

Title: Diaphragm selection mechanism
Inventor: TAMURA TOMOAKI
IPC: G02B7/28
Filed: 1989-10-17
Abstract: PURPOSE:To execute the selection of diaphragm and the switching of the shortest photographing-enabled distance of a photographing lens by the use of one driving source by driving and rotating a diaphragm plate so that a diaphragm hole is selected and moving the optical system being the photographing lens through a cam mechanism so that the shortest distance may be switched. CONSTITUTION:When a stepping motor 25 is rotated, a lever part 29 arrives at a photographing lens movement part 24c. The optical system 22 being the photographing lens moves backward and the diaphragm plate 21 rotates, then the lever part 29 arrives at a standard area diaphragm selection part 24a. Since the standard area diaphragm selection part 24a is formed in a direction orthogonally crossed with an optical axis O, the diaphragm plate 21 rotates but the optical system 22 being the photographing lens does not move toward the optical axis O, and the diaphragm hole 21a for standard is selected by the rotation of the diaphragm plate 21. Thus, the selection of the diaphragm and the switching of the shortest photographing-enabled distance of the photographing lens are executed by the use of one driving source(the stepping motor 25) and the structure is simplified.

IPC: G09F9/35
Filed: 1985-11-30
Abstract: PURPOSE:To accurately and uniformly set the space between substrates and to prevent the movement of spacers so as to improve display quality by disposing the spherical spacers consisting of an org. material which is elastically deformed when pressed by the substrates between the two substrates enclosed by a sealing material incorporated therein with inorg. material spacers. CONSTITUTION:The inorg. material spacers, for example, glass fibers 17 are incorporated into the sealing material 15, by which the space provided to seal a liquid crystal between the two substrates 11 and 13 is exactly set and controlled. The spherical spacers 19 consisting of the org. material which are pressed and elastically deformed by the substrates 11, 13 are used between the two substrates enclosed with the sealing region by the material 15 (for example, display part). Restoring force generated by the deformation of such spacers 19 acts on the substrates 11, 13 and therefore, the space between the substrates is accurately and uniformly set without the movement of the spacers 19 between the substrates 11 and 13 and without the consequent damage of the oriented films of the substrates.

Title: Method for measuring discharge quantity of pile material in pile placing construction
Inventor: AKAMATSU TAKEHITO
IPC: E02D3/08
Filed: 1990-10-11
Abstract: PURPOSE:To improve the accuracy of measurement of discharge quantity of the pile material by detecting the sound wave of an inline air column with two microphones provided inside of a casing and inside of a fitting cable connected to the casing, and obtaining a position of the top surface of the pile material on the basis of the detecting signal. CONSTITUTION:The sound wave is radiated from a speaker 34 to the inside of a casing 2 by a sound generating device provided outside of the casing 2. The resonance sound of this sound wave is detected by a first microphone 36 provided inside of the casing 2 and a second microphone 41 provided in a spherical and hollow fitting case 40 connected to the peripheral part of the casing 2, and the detected signal is output to a frequency analyzer 37. Resonance frequencies f0, f1 are analyzed by the frequency analyzer 37 to be transferred to an inline air column computing unit 38, and length l of the inline air column is obtained to compute a top surface position of the pile material 5. Discharge quantity of the pile material is thereby measured independently from the distribution of temperature.

IPC: G06F3/048
Filed: 1988-10-28
Abstract: PURPOSE:To detect a hidden window by means of simple operation while holding the layout of a whole screen by updating screen display in such a way that the larger a window gets in area, the lower the window gets in display priority in response to the arrangement command of the windows. CONSTITUTION:Window control information such as the positions, sizes, display priority of the windows 101-104 are stored. When the arrangement command of the windows 101-104 is inputted, the areas of the windows displayed on the screen 100 are calculated, and the display priority of respective windows is updated in such a way that the larger the areas the lower they become in the overlap of respective windows. Respective windows are re-displayed in order from the window with the least significant priority toward the window with the most significant priority. Thus, the window which is hidden behind the large window and was unable to see appears again on the screen, and the objective window can easily be estimated.
