Title: Excavator for trench of underground continuous wall
Inventor: OOHIRA TAKUYA
IPC: E02F5/02
Filed: 1983-01-13
Abstract: PURPOSE:To easily alter the thickness of excavated wall by a method in which a soil suction port is provided in the middle of two rotary bits, the bits and an excavator are connected with an expander, and the bits are rotationally operated by remote operation. CONSTITUTION:Excavation is made by rotary bits 34 while guiding an excavator 3 with wheels 25 on a guide rail 24, and excavated oil and sand are sucked into a soil suction port 41 and sent to the ground surface through a discharge pipe 42 by a pump 32. When altering the thickness of excavated wall, a jack 52 is expanded or shrunk, a bit base 54 is turned, and any thickness of the excavated wall is set up. Afterwards, excavation is made by the rotary bits 34. The thickness of excavated wall can thus be easily altered without exchanging the bits, thus permitting economical design.

Title: Driving method for liquid crystal matrix panel
Inventor: WAKITA HISAHIDE
IPC: G02F1/133
Filed: 1988-01-08
Abstract: PURPOSE:To obviate an uneven luminance by shifting the phase of a selection period of a scanning electrode and a signal electrode and varying a first pulse of a non-selection period of the scanning electrode which follows a write pulse, in accordance with data of a selected picture element. CONSTITUTION:One selection period is constituted of four pulses, but the phase of a scanning electrode and a signal electrode is shifted by a two-pulse portion of 1/2 of one selection period. In such a state, in case of the shown figure, a picture element is reset by a pulse of the right-up oblique line part, and when a write pulse of the left-up oblique line part is larger than a threshold voltage, the picture element is inverted and goes to white, and when the write pulse is smaller than the threshold voltage, the picture element goes to black. In any pattern, in case of the write pulse > the threshold level, the first pulse of a non-selection period goes to the same polarity as the write pulse. Therefore, an uneven luminance of the picture element depending on a pattern, which has occurred by a conventional method is generated, and also, since it expands by a driving margin, a display being uniform and having a high contrast is obtained.

Title: Radioactive ray detector
Inventor: YOSHIDA YUZO
IPC: G01N23/04
Filed: 1989-01-10
Abstract: PURPOSE:To obtain a detector with high resolving power in a simple structure by using a scintillator wherein a size value in a thicknesswise direction of incident radioactive rays is rendered smaller towards end parts in a direction crossing the arranging direction of said scintillator from the central part thereof. CONSTITUTION:A scintillator 12 is arranged so that the size value in a thicknesswise direction (shown by an arrow A) of incident radioactive rays is smaller from an intermediate part 12c to end parts 12a, 12b in a direction crossing the arranging direction of the scintillator 12. The scintillator in a polycrystal structure is relatively opaque by the influences of the existing interface, and an optical output becomes maximum when the size value is a specific thickness t1. When the size value is not less than or not more than the thickness value t1, an optical output tends to be lowered. Therefore, the size value of the end parts 12a, 12b of the scintillator 12 can be decided in consideration of this tendency. Thus, the resolving power at the end part can be improved, and a clear image can be obtained.
