Title: Clogging prevention device for trommel
Inventor: MORIMOTO TADASHI
IPC: E21D9/12
Filed: 1998-12-09
Abstract: PROBLEM TO BE SOLVED: To prevent clogging of a trommel by providing tip parts with teeth protruding from meshes of a basket of the trommel and providing a rotary body rotating following rotation of the basket due to the engagement of the teeth with a lattice of the basket. SOLUTION: When a basket 21 of a trommel 1 rotates in the direction of arrow mark, teeth 31 meshes with a lattice of the basket 21, and a rotary body 29 rotates following rotation of the basket 21 in the same direction as the basket 21. The number of revolutions of the rotary body 29 at this time is expressed by, for example, equation, n=N.w/t (wherein, N: the number of revolutions of the basket, n: the number of revolutions of the rotary body, t: the number of teeth of the rotary body, w: the number of lattices in one cross section of the basket). When the rotary body 29 rotates, each tooth 31 is inserted into each lattice to push out earth clogged in a mesh of the lattice and scrape and drop clay adhered on a longitudinal rod due to the contact of the longitudinal rod and the tooth 31 at the time of rotation.  Consequently, it is possible to remove adhered clay and mud water surely and prevent clogging of the trommel.

Title: Instrument and method for measuring shape
Inventor: OKABE MASAHARU
IPC: G06T7/00
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To measure the shape of a transparent body with accuracy even when both front reflection and rear reflection occur and, at the same time, to simultaneously measure the front and rear surfaces of the transparent body by picking up the image of reflected light from at least either the front surface or rear surface of the transparent body and processing the image. SOLUTION: Light from a light source 1 is passed through a slit 2, condensed through a lens 3, and projected upon a transparent sample 4. The image of reflected light from the sample 4 is formed in a lens 5 and picked up with a TV camera 6. An A/D converter 8 digitizes the TV signal of the camera 6 and a picture processor 9 measures the shape of the sample 4 from the digital data. Because of refraction in the sample 4, a deviation is produced between reflected light 12 from the front surface of the sample 4 and reflected light 13 from the rear surface of the sample 4. Therefore, the image 121 of the reflected light from the front surface and the image 131 of the reflected light from the rear surface are picked up with the camera 6 with a deviation between the images 121 and 131.  Since the reflected light rays from the front and rear surfaces can be detected separately when the deviation amount is increased and the slit 2 is made narrower in width, high-contrast video signals can be obtained. In addition, it becomes possible to stably catch the reflected light from the rear surface only.
