Abstract: PURPOSE:To upgrade treatment efficiency and to economically treat contaminated grit by disposing a separating body having many through-holes to a water surface part, introducing the scum-contg. contaminated grit into said body and oscillating the separating body in a vertical direction. CONSTITUTION:This invention relates to a treatment of the contaminated grit from a grit chamber, etc., in a pumping station and sewage treatment plant, in which part of the entire part of the separating body 3 having the many through-holes is disposed to the water surface part. This body 3 is oscillated in the vertical direction so as to be alternately positioned under and above the water surface. Then the water flow accompanying the bubbles B arises in the part of the through-holes 4a according to the oscillation and the contaminated grit S contg. the scum N on a separating plate 4 is washed by the water flow and is separated to the scum N and the grit S. The grit S in the through- holes 4a receives the water flow and the fine waste M and sand component S1 settle from the grit S when the plate 4 moves upward from the submerged state. Highly efficient and economical treatment of the contaminated grid is thus executed.

Title: Collapsible barrel housing system interchangeable zoom lens-barrel
Inventor: SUGANO HIDEO
IPC: G02B7/04
Filed: 1988-07-15
Abstract: PURPOSE:To improve a compact character at the time of non-using and a portability by extending the cam groove of an inverted cam in a direction to conduct a first lens at a lens mounting side in operating a zooming operating member further in addition to a length necessary for a zooming action. CONSTITUTION:When a zoom ring 9 is rotated from a telephoto position and a character 9c is aligned to an index line 6d, a pin 8 is further moved along a linear part 4c of a cam groove 4e of a cam ring 4, and it comes to a housing position. By the rotation of the zoom ring 9, a pin 5 is also moved further along a curve 2c of a cam grove 2e of one group moving frame 2, and it comes to the housing position. Consequently, the one group moving frame 2 is moved at an optical axis direction camera side along with an L1 lens holding barrel 1 and a lens L1. Since the curve 2c is comparatively drastically curve din the optical axis direction, by the slight rotation of the zoom ring 9, the large optical axis direction movement of the L1 lens holding barrel 1 can be obtained, and a zoom lens lens-barrel can be located in a sinking barrel housing position. Thus, the optical axis direction overall length at the time of non-using can be shortened.

Abstract: PURPOSE:To feed recording sheets of paper of a format complying with the document size by placing documents of different sizes in the specified one of a plurality of hoppers, sensing the size while documents are preliminarily fed, distributing them to the hoppers for reaccommodation, and feeding appropriate recording sheets in conformity to the information recalled from the memory about the document sizes and the hoppers accommodating them. CONSTITUTION:If documents D of sizes A4 and A3 are loaded in a hopper 3a mixedly, a preliminary information is issued, and they are fed to the transport path 16 one after another by a document feeding means 9a. The size is read by a size sensor 32, and a conversion pawl 40 is operated according to the size read, and A1 documents are put in the hopper 3a while B1 documents in another hopper 3b. When a sensing means 8a judges that the initially loaded documents D have been cleared, the copying process is commenced. The sheet feed information for the hoppers for reaccommodation 3 is stored in a memory, and copying is made on the recording sheets of paper complying with the document size. This avoids improper copying performance such that part of the image is missing.

Title: Spring type brake for press driving shaft
Inventor: KUBO TAKESHI
IPC: B30B15/10
Filed: 1988-07-14
Abstract: PURPOSE:To relax a shock at the time of stop, while adjusting a rotating speed rate of a press driving shaft by providing a torque controller formed by containing an energizing force reducing means for reducing suitably energizing force of a spring of a control mechanism. CONSTITUTION:When a damping mechanism 10 is operating, it is detected by a rotating speed detector 41 that a press driving shaft 5 is immediately before a stop. Based on this detection, a damping force adjusting circuit 61 operates an energizing force reducing means 31 by a set time. The energizing force reducing means 31 reduces spring energizing force by applying force opposing the energizing force of a spring 13. Accordingly, a rotating speed decrease rate of the press driving axis 5 can be made small, and a shock at the time of stop can be relaxed. After the set time, desired damping force is secured by the maximum energizing force of the spring 13. Therefore, exact and smooth press working is guaranteed, and also, a long service life of a machine is attained.
