IPC: B28D7/04
Filed: 1988-09-29
Abstract: PURPOSE:To attempt to cut efficiently and automatically a plate material by utilizing a joint formed on the surface of the plate material as a standard by positioning the plate material by moving a guide fitted with proximity sensors and detecting a transverse groove by means of the proximity sensors to cut the plate material into a required dimension by means of a vertical saw. CONSTITUTION:A guide 14 fitted with sensors S2, S3, S4 and S5 is driven by a motor 18 to position the proximity sensor S2 etc., to a vertical saw 6. A back-up fitment 19 is rapidly forwarded to push a plate material W and is stopped when photoelectric switches P1 and P2 detect the edge of the plate material W. A proximity sensor S1 is lowered on the upper face of the plate material W. When the proximity sensor S1 is actuated as OFF-ON, it detects a transverse groove N. When the transverse groove N is detected and the plate material W is stopped, a clamp vise 11 of a longitudinally moving apparatus holds the plate material W and moves backward while it holds the plate material W. A longitudinal groove M is detected by the proximity sensor S and it is stopped when the position of the longitudinal groove M is detected. After the plate material W is held by the clamp vise 9, it is cut by means of a longitudinal saw 6.

Title: Electrostatic oil purification machine
Inventor: SAKAMOTO AKIHIKO
IPC: B03C5/00
Filed: 1993-09-09
Abstract: PURPOSE:To prevent such phenomena as rusting and corrosion from generating while executing an electrostatic oil purification by detecting a current value correlative to the quantity of dust captured by moisture contained in an insulative liquid and arranging a moisture content percentage detection part for calculating a moisture content percentage in accordance with variations of the current value. CONSTITUTION:This electrostatic oil purification machine consists of an electrostatic oil purification tank 1 composed of a dust collector 13 arranged between a negative high voltage electrode plate 11 and a positive earthed electrode plate 12, both being opposed to each other. A high voltage of about 10KV is applied to an area between both electrode plates by a high voltage generation part 2. In addition, the dust collector 13 is made electrically conductive by allowing moisture to be adsorbed from a turbine oil using the dust collector 13, and a microcurrent running through the dust collector 13 is detected by a moisture content percentage detection part 3. When water is contained in the turbine oil, in this case, the current value detected by the moisture content percentage detection part 3 increases with the elapse of the operating time of the electrostatic oil purification machine, and the increase rate is closely related to the moisture content percentage of the turbine oil. Thus it is possible to remove a contaminant in various insulative liquids such as turbine oil and detect exactly the moisture content percentage of the liquid.

Abstract: PURPOSE:To correct the white balance of an automatic following type in a wide illuminance range by providing a correction signal switching circuit selecting a white balance correction signal based on an output decided by an illuminance detection circuit and selecting a white balance correction system in accordance with the level of illuminance. CONSTITUTION:The 1st white balance control signal and 2nd one are inputted to the correction signal switching circuit D, which inputs the white balance correction signal selected based on the illuminance decision output to said color level control circuits 8 and 9. When the illuminance decision output at a high level is inputted at high illuminance, the 1st and 2nd switches 18 and 18 select the 1st white balance control signal. If the illuminance decision output at a low level is inputted, said switches select the 2nd white balance control signal. Under low illuminance where the 1st white balance correction circuit A cannot operate, the 2nd white balance correction signal is supplied to the color level control circuits 8 and 9. However, a slight color deviation may occur under the low illuminance, which can be visually negligible.
