Title: Disposal of water containing slight amount of organic substance
Inventor: TAKAHASHI ISAO
IPC: C02F9/00
Filed: 1980-06-04
Abstract: PURPOSE: To miniaturize an installation for producing a required amount of superpurified water and to save consumption of chemicals, by treating water, which has been treated with the conjunct use of hydrogen peroxide and ultraviolet rays, in a reverse osmosis device and then in a polisher comprising a mixed bed-type ion exchange tower.  
     CONSTITUTION: Water A to be purified, esp. waste water used for washing electronic parts or the like, which contains a slight amount of organic substances, i.e. about 20mg/l or less of CODcr value, is introduced into a photooxidizing device 40. In the device 40, the organic substances in water A are oxidized and decomposed to a level of about 1mg/l or less with the conjunct use of H 2 O 2  and ultraviolet rays. Water A is then treated in a reverse osmosis device 20. In the device 20, a few ppm of H 2 O 2  may be preferably present for preventing the generation of slime. Water A is further introduced into a polisher 30 comprising a mixed bed-type ion exchange tower, and treated there. As a result, impurities are nearly perfectly separated from the water. Consequently, regenerated waste washing water can be reused as superpurified water.

Title: Cylinder for gas compressor, and gas compressor
Inventor: SHIMADA KOICHI
IPC: F04C29/06
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To provide a gas compressor which is intended to reduce in membrane vibration in the vicinity of cylinder discharge hole. SOLUTION: A gas compressor is such that a discharge valve mounting part 131 is formed by notching the region ranging from the position of a discharge port 7 to the front side in the rotation direction of a vane 5, of the outer peripheral wall of a cylinder block 13. The thickness in a radial direction of the cylinder block 13 is relatively further increased in the vicinity of a discharge hole 7 and at the part on the part on the completion side of a compression stroke by a vane 5 than at other part and the completion part of the compression stroke is maximized. Thereby, the thickness in a radial direction of the cylinder block 13 is relatively further increased at the part, where an internal pressure occasioned by the compression stroke is high, of the cylinder chamber 2, and the thickness of a part where an internal pressure is a maximum is increased to a maximum.  Thus, since, at the cylinder block 13, rigidity of a part where an internal pressure is high is improved, the generation of membrane vibration at the periphery of the discharge hole 7 is reduced and the generation of noise due to membrane vibration is reduced.

Abstract: PURPOSE:To prevent the occurrence of overmuch bending moment to the head of a pile by absorbing the energy of horizontal forces by interposing a buffer layer composed of sand or gravel between the steel plate on the downside of the fotting to support the superstructure and the lower pile. CONSTITUTION:A pile 3 is driven, a plate or sheet 4 is laid by covering the head of the pile, and a buffer layer 5 composed of sand or gravel is laid on the plate or sheet 4. In this case, as needed, the buffer layer 5 is compacted by vibration, the plate or sheet 4 is folded to embrace the buffer layer 5, and then a steel plate 2 is set. A necessary formwork is assembled on the steel plate 2, concrete for the footing 1 is placed into the formwork, the formwork is removed, and the surrounding of the footing 1 is embedded with soil and sand. The energy of the horizontal forces is absorbed by the breaking phenomenon of the sand or gravel granules. Since the head of the pile is not fixed thereby, the occurrence of overmuch bending moment can be prevented.

Abstract: PURPOSE:To obtain high measurement accuracy with less number of optical fibers by providing a vernier part consisting of n+ or -1 pieces of optical fibers relatively movably to a normal scale part consisting of n pieces of regions reflecting to specific wavelengths. CONSTITUTION:The white light from a white light source 16 is allowed to arrive at an optical branching and combining device 14 as well as a branching filter 17 connected to a decoder 20, a binary coding circuit 19 and a photodetector array 18, by way of a half mirror 15.

IPC: B41J2/00
Filed: 1987-03-27
Abstract: PURPOSE:To perform efficient operation even when a large number of host apparatuses are connected, by mounting the memory means corresponding to the host apparatuses. CONSTITUTION:After data is stored in a buffer memory 7-1, a host apparatus 1-1 is opened to perform other work. The image data stored in the buffer memory 7-1 is outputted to a printer 8 by the control of CPU 4 to perform printing. When a host apparatus 1-3 outputs printing data in such a state that printing is performed, the output data of the host apparatus 1-3 is given to an input interface 5 by a multiplexer 2 and a channel indicating circuit 3. This data is once stored in the buffer memory 7-3 corresponding to the host apparatus 1-3 and said host apparatus 1-3 is opened to perform other work. The printing of the data stored in the buffer memory 7-3 is performed after the printing of the data stored in the buffer memory 7-1 is finished. Therefore, a memory means is not occupied by the printing data from one host apparatus and output efficiency is made well.
