Filed: 1991-12-26
Abstract: PURPOSE:To prevent damage being due to malfunction in a lever and a bracket by engaging the lever with the bracket to lock the front end of a deck for preventing the vertical movement of the front end, and moreover, during the engagement of the lever with the bracket, discontinuing the functioning of deck tilting means. CONSTITUTION:In the case where a dump truck travels with cargoes loaded on a deck, when the tip 9a of a lever 9 is detached from a bracket 3, a switch 6 is turned on, and a control means thereby sets up the tilting means of the deck so as to be functionable. On the other hand, in the case where the dump truck travels with no cargo loaded on the deck, when the lever 9 is rotated until the tip 9a abuts on a stopper member 5, the lever 9 engages with the bracket 3 and is locked. When the lever 9 is locked, the vertical movement of the front end of the deck disappears, and the occurrence of abnormal sound is prevented. In addition to that, when the above state is produced, the switch 6 is turned off by the tip 9a of the lever 9 to discontinue the functioning of the deck tilting means. Thus deck tilting action caused by malfunction is eliminated to prevent damage in the lever 9 and the bracket 3.

Abstract: PROBLEM TO BE SOLVED: To prevent break, flaw and crack after a slicing process in the case where a single crystal bar of a large diameter is sliced by using a wire saw, by etching a semiconductor wafer sliced from a semiconductor single crystal bar, before sending the semiconductor wafer to a next process. SOLUTION: An etching process X is inserted immediately after a slicing process A. As a result, a part of or an entire damaged layer on the surface of a semiconductor wafer generated by slicing can be removed. Thus, by inserting the etching process X after slicing of a semiconductor single crystal bar, the strength of the wafer after slicing can be recovered, and generation of break, flaw and crack of the wafer due to distortion applied by the slicing process A can be prevented in a process subsequent to the slicing process A. Particularly, an advantage of a wire saw which enables high-speed slicing and less slicing margin in the case where a single crystal bar of a large diameter is sliced can be utilized.

IPC: G02F1/1337
Filed: 1998-12-03
Abstract: PROBLEM TO BE SOLVED: To obtain a display element which ameliorates the display defect due to imperfect surface pressing and has high fineness and high grade. SOLUTION: This liquid crystal display element formed by aligning and end-sealing liquid crystals 14 between a pair of transparent substrates 1 and 2 and arranging many pixels in row and columns directions is set with a pixel pitch (d) and pretilt angle (x) at a range where the surface pressing resistance Y expressed by Y=0.22e(0.011d)(x) attains the value larger than the preset value when the surface pressing resistance is defined as Y(kgf/cm2), the pixel pitch as d(μm), the pretilt angle as x( deg.) and e is the base of logarithm. The pretilt angle (x) is set at 2 to 6 deg. when the pixel pitch (d) is <=100 μm.  The surface pressing resistance improves as the pretilt angel is larger and, therefore, even if the higher fineness of <=100 μm in the pixel pitch (d) is attained, the sufficient surface pressing resistance is assured by the pretilt angle (x) of 2 to 6 deg., by which the display defects of the surface pressing defect, disinclination, etc., are ameliorated and the visual field angle is widened with low electric power consumption. The element having the high contrast and high display grade may be obtained.
