Title: Waste liquid treating device for waterless planographic printing plate
Inventor: SHIGETAKA SEIJI
IPC: G03D13/00
Filed: 1991-06-14
Abstract: PURPOSE:To treat a waste liquid while preventing the stagnation of development scum around a discharge pipe and admitting the scum smoothly into the discharge pipe. CONSTITUTION:The shape at the top end of an overflow pipe 70 is formed as a tapered part 70A of the diametral size decreasing gradually toward the top end on the outer periphery thereof. Since the contact surface of the development scum 18A is thereby sloped, the development scum 18A flows smoothly down into the overflow pipe 70. Polypropylene(PP) is applied to the material of the overflow pipe 70. The surface tension of this PP has 29.7mH/m (=dyn/ cm) and is of the value much lower than 41.9mN/m which is the surface tension of a vinyl chloride which is heretofore used. The development scum 18A is, therefore, smoothly admitted into the overflow pipe 70 along the above- mentioned slope as the adhesion of the scum to the pipe when the scum touches the pipe is decreased. Polyethylene having <=37mN/m surface tension, 'Teflon (R)'(21.5 to 23.9mN/m) having <=30mN/m, etc., are applicable as other materials.

Title: Sample holder for dynamic anisotropy measurement by ultrasonic wave
Inventor: IMAMURA TORU
IPC: G01N29/00
Filed: 1985-06-28
Abstract: PURPOSE:To quantitatively measure the anisotropy of various materials by using an ultrasonic transversal wave by mode conversion to measure the anisotropy of the material without contacting. CONSTITUTION:A parallel moving base 1 finely adjusts the sample position by a microscrew 2 and sets the space between an oscillator and the sample according to the focal length, etc. of the oscillator. A rotary knob 3 rotates a sample holder holding part 4 and adequately sets the incident angle of the ultrasonic wave to the inside of the sample by rotating angle scales 5, 6. The transversal wave is propagated in the sample by the mode conversion. A sample holder 7 fixes the sample for measuring the anisotropy and rotates in the sample plane with the holding part 4 as a guide. The sample is set to an optional angle by the scale inscribed on the holder 7 by using reference line inscribed to the holding part 4. The moving base 1 moves the sample position according to the position of the oscillator and the scale 6 sets the incident angle of the ultrasonic wave to the inside of the sample. On the other hand, the holder 7 rotates the sample within the sample plane to set the incident angle to the inside of the sample. The anisotropy of the material is thus quantitatively determined.

Title: Separation device of transcription member
Inventor: ADACHI HIROYUKI
IPC: G03G15/14
Filed: 1980-10-14
Abstract: PURPOSE:To ensure the separation of a transcription member in good condition by the rectification of a low speed and low level of voltage, by setting the angle of opening through which the separated air is flowed out at a prescribed value and then flowing out a part of the isolated air current toward the tangent line of a photosensitive drum. CONSTITUTION:A pipe 7 is installed so as to set the angle theta1 at a value smaller then the angle theta2. The angle theta1 is formed with a straight line PA connecting the center point P if the pipe 7 and the center point O of a photosensitive drum 1; while the angle theta2 is formed by the center point P and the tangent line PC of the drum 1. Owing to such setting of positions, the 20-50% air current F of that flowing out through the opening 8 flows toward the tangent line of the drum 1. Thus an air current E which is protected from the disturbance turns into the rectification. As a result, a transcription member can be separated from the drum 1 in good condition and in a simple way in that the rectification of a low speed and low level of voltage. If this case, a better effect is ensured by setting the line OB parallel to a horizintal line.
