Title: Excavating settlement of caisson
Inventor: SENDA SHIYOUHEI
IPC: E02D23/08
Filed: 1984-06-19
Abstract: PURPOSE:To raise the settling efficiency of a caisson by a method in which while excavation is made by an expansion type excavator, a liquid-pressure cylinder is contractionally moved, and support beams and a caisson supported by the support beams are concurrently lowered. CONSTITUTION:The upper end of a caisson 3 is connected to the support beam 2 of an elevating supporter having a liquid-pressure cylinder 1 for vertically moving the support beam 2. An expansion type excavator 4 is hung down from the beam 2 for supporting. The excavating cutter 5 of the excavator 4 is expanded and opened and positioned below the lower end of the caisson 3, and the excavator 4 is operated for excavation. The cylinder 1 is contractionally moved and the beam 2, the caisson 3, and the excavator 4 are concurrently lowered. The settling efficiency of the caisson 3 can thus be raised by such a simplified process, and the degradation of the pit wall can be prevented.

Title: Production of 3-chloropropene
Inventor: KITAMURA TORU
IPC: C07C21/067
Filed: 1985-06-10
Abstract: PURPOSE:To obtain the objective compound from 1,2-dichloropropane in high yield, suppressing the side reaction, etc., by carrying out the dehydrochlorination of the above raw material in a molten salt at a specific temperature in the presence of oxygen and/or water. CONSTITUTION:3-Chloropropene useful as a raw material of epichlorohydrin can be produced economically by the dehydrochlorination reaction of 1,2- dichloropropane in a molten salt (especially and alkali metal or alkaline earth metal chloride) at 400-750 deg.C, especially 500-700 deg.C in the presence of oxygen and/or water. The amount of oxygen and water is 0.01-100wt%, especially 0.05-50wt% each. Since the temperature of the reaction system is maintained uniformly by the molten salt, the side reactions such as the decomposition of the produced objective compound, etc., can be suppressed and the selectivity of the compound can be improved remarkably. Furthermore, the coking phenomenon is suppressed by the addition of oxygen and water to enable the continuous operation of the reaction apparatus for a long period.

Title: Ccd driver
Inventor: TSURIBE SATOYUKI
IPC: H04N5/341
Filed: 1992-05-19
Abstract: PURPOSE:To improve the picture quality by applying CCD drive taking preceding smear reduction over others to a high brightness object and applying CCD drive taking preceding fixed pattern reduction over others to a usual brightness object. CONSTITUTION:An FIT type CCD 101 is driven by an H driver 102 and a V driver 103 and outputs a video signal to an image pickup level detection circuit 105. The level of the video signal is negative in a CCD output and when a level below a threshold level TH is inputted, it is discriminated that an object with high brightness is picked up and a control signal is sent to the V driver 103 to select the smear reduction CCD drive from the usual fixed pattern noise reduction CCD drive. When the control signal is inactive, a CCD drive pulse of the fixed pattern noise reduction is given to the FIT type CCD 101. Thus, a substrate voltage generating section 203 allows the FIT type CCD 101 to generate a voltage just before charge injection with an output voltage of a drive voltage generating circuit 201 to make control to maximize the sensitivity.

Abstract: PURPOSE:To make precision machining unnecessary and also make the phenomenon of galling difficult to take place for stabilizing the characteristics and extending the life by sealing viscous liquid and solid particles in a rotating casing. CONSTITUTION:When this vibration suppressing device is mounted on a body, the vibration of which is to be suppressed, with the vibration of the casing 3 the inertial body 10 receives the vibratory force only through viscous liquid 5.
