Title: Construction method of continuous underground wall
Inventor: NAITO TEIJI
IPC: E02D5/20
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To make it possible to change the thickness of an underground wall to comply with stress and thereby execute work by inserting a cage which reduces its upper wall thickness into an excavated ditch and inserting a wedge- like pull-out form into the ditch in such a state that its maximum width side may be positioned on the upper part and then placing concrete. SOLUTION: A general excavating machine is used to excavate a ditch whose thickness is uniform from the upper end to the bottom where the ditch is excavated while a stabilizing liquid is being filled up. Then, a cage 2, whose upper part is thinly shaped up, is lowered and inserted into the ditch. Then, a wedge- like pull-out type form 3 is inserted into the ditch and then concrete is placed into the ditch. When the concrete is cured and unaided support is available, the wedge-like pull-out form 3 is pulled up to the ground. Then, a slope-shaped space is produced in that area. To comply with this, a backfill material is filled up so as to prevent the collapse of the ditch if the space is located on a natural ground side. This construction makes it possible to change the thickness of an underground wall, responding to stress and thereby execute work.

IPC: B21B37/00
Filed: 1980-04-26
Abstract: PURPOSE:To control the breadth with high accuracy, by installing a sensind roll for detecting the breadth and hardness of the slab just before the feed-in side of the vertical roll, and by controlling the rolling reduction and time lag according to the displacement of the sensing roll and output of the tachometer. CONSTITUTION:The vertical rolls 2 are set at the edging position for the slab 7 to be rolled, and the cylinder is extended to push the sensing roll 20 through the pin and arm so as to touch both edges of the slab 7. Then, if the slab 7 goes forward, the sensing roll 20 is pushed, and the arm is turned around; this turning motion is detected by the turning angle detector 25 whose output signal together with the output signal of the hardness detector 31 connected to the load cell are inputted to the reducing roll controller 34. The controller 34 thereupon determines the correction value for the rolling reduction of the vertical rolls 2, and the computer 36 for computing the correction value for the time difference computes the time lag according to the signal sent from the tachometer 28, and then, the screw down hydraulic cylinder 5 is operated according to these outputs of the controller 34 and the computer 36.

Title: Hollow hole casting method of long-sized casting
Inventor: KAWAGUCHI MASATOSHI
IPC: B22C9/24
Filed: 1984-03-23
Abstract: PURPOSE:To prevent bending of a core for hollow hole casting and to form a long-sized casting having no thickness deviation by hollow hole casting by supporting freely slidably the core to a core supporting material provided to have the gap to permit elongation of the core owing to thermal expansion at one end of a casting mold. CONSTITUTION:The molten metal poured through a sprue 502 is filled through a runner 5 and a communicating part 501 into a molding groove 4 to perform hole casting with a core 6. The core 6 is thermally expanded by the heat of the molten steel so as to elongate axially. The upper part 602 of the core 6 is supported by a supporting member 9 and since said part is supported freely axially slidably by a supporting hole 901, the expansion in the elongating direction is permitted and the thermal expansion is absorbed. The cast can shaft is thus formed in such a way that the wall thickness around the hollow part thereof is made uniform in relation with the shaft part thereof without bending of the core 6 while the hollow part is maintained straightforward without deformation.

IPC: H01L21/027
Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To numerically estimate the shape of a resist pattern in a relatively short calculating time, in consideration of the effect of standing wave which depends on the film thickness and material of the resist and the material of the substrate. SOLUTION: The threshold of the concentration of a photosensitive agent which becomes a reference for estimating the shape of a resist pattern is determined based on the by conditions such as film thickness and material of resist film and material of substrate. The threshold is applied to the distribution of the photosensitive agent concentration obtained by calculation on photosensitivity inside the resist. Size and shape of the resist pattern are directly predicted numerically omitting the process of development calculation which requires a long time.

Title: Observation of magnetic domains with scanning electron micorscope
Inventor: TSUNO KATSUSHIGE
IPC: H01J37/28
Filed: 1981-04-15
Abstract: PURPOSE:To enable the structure of magnetic domains, which are magentized perpendicular to the surface of a sample, to be clearly observed with a high multiplying factor by slanting the sample from an axis perpendicular to the axis of electron rays, slanting the sample from the axis perpendicular to both of the said axes, and installing a detector detecting scattered electrons within the space opposed to the surface of the sample. CONSTITUTION:A sample 1 is slanted from an axis X, which is perpendicular to an electron-ray axis Z, by an angle of alpha. Due to the above slant of the sample 1, a magnetization Ms of each magnetic domain develops a magnetic component of Ms sinalpha in X direction. In addition, the sample 1 is slanted from a Y-axis, which is perpendicular to both the X and the Z axes, by an angle of theta. By thus setting the sample 1, the magnetic Ms sinalpha component corresponds to the direction of the magnetization, and electron rays are easily or hardly discharged from the surface of the sample 1 according to the area of the sample 1. After that, reflected electrons scattered from the sample 1 are detected with a detector 2, and are introduced into a cathode-ray tube. The detector 2 is installed opposed to the sample 1, at an appropriate position within a space surrounded by the X, Y and Z axes.
