Title: Synthetic resin netted tube
Inventor: NOGUCHI TAKASHI
IPC: F16L9/12
Filed: 1983-03-03
Abstract: PURPOSE:To provide a sufficient strength against external pressures for a synthetic resin netted tube by using small amounts of resin by providing a mechanism by which external pressures are received by a pressure-resistant action possessed by the resin thickness of a spiral resin belt wall and a pressure-resistant action of air possessed by the follow portion of the resin belt wall. CONSTITUTION:Large numbers of hollows 4 having an enclosed space structure surrounded by inner and outer walls 51 and the almost radially directed wall portion of a pile connecting inner and outer walls 51 or a thick circumferential wall 52 having the almost radially directed wall portion of the tube are provided in the longitudinal direction. Large numbers of openings are formed in the outside or inside circumferences of spiral resin belts 2 wound at adequate intervals by crossing large numbers of parallel linear resin belts 3 or linear resin lines at intervals in the axisial direction of the resin belts 2 and combining them integrally at crossed points. In the main skeleton having the resin belts 2 in a tubular form, in case where external pressures apply to the synthetic resin netted tube 1, the external pressures are received synergistically by a pressure-resistant action by the resin thick in the almost radially directed portion of the tube in the circumferential wall 52 and a pressure-resistant action of air embraced in the hollows 4.

Title: Molecular weight control of styrenesulfonate polymer
Inventor: OOBA RIYOUJI
IPC: C08F2/00
Filed: 1981-03-11
Abstract: PURPOSE: To carry out the production stably and easily, by adding a monomer and a polymerization initiator at controlled rates to the polymerization system, in producing a styrenesulfonate polymer having a desired MW by varying the amount of a polymerization initiator.  
     CONSTITUTION: A styrenesulfonate or its mixture with other ethylenically unsaturated monomers (e.g., acrylic acid and acrylamide) is dissolved in water, and this solution is added gradually at a constant rate to the reaction system. At the same time, a polymerization initiator (e.g., sodium persulfate or hydrogen peroxide) in an amount controlled according to the desired MW is added gradually at a constant rate to the polymerization system. The resulting reaction mixture is then reacted. This makes it possible to control the MW of the formed polymer stably. When the polymerization initiator/monomer ratio increase, the MW of the formed polymer decreases.

Filed: 1990-02-15
Abstract: PURPOSE:To reduce noise and to facilitate maintenance by cooling the internal part of a sealed case through the use of an electronic cooling element (thermoelectric cooking device) using Peltier effect. CONSTITUTION:An electric cooler 21 is that using the electronic cooling element which uses Peltier effect. The internal part of the case 2 is cooled by heat exchange in a cooling air discharge port 23. Heat absorbed by heat exchange is transmitted to the external part of the case 2 and the internal part is cooled by outside air C taken in from an intake port 22, whereby it is discharged as hot air D. Consequently, the internal part of the case 2 can be cooled without transmitting outside air C into the internal part of the case 2 and the case 2 can be set to sealed structure. A cooling fan and a fan guard in a structure part deck are eliminated. Thus, the case is cooled with less noise and with easy maintenance.

Abstract: PURPOSE: To effectively utilize paper resources by realizing optimum copying operation according to the number of original pages. CONSTITUTION: This recorder is provided with a means for arithmetically operating information on the original pages and a means for deciding a mode based on the arithmetically operated result; and the arithmetic means divides the number of original sheets by 4 and obtains a remainder (S100), the mode decision means judges the remainder value (S101), and starts copying by judging that signature copying can be executed when the remainder is 0 or 3(102). When the remainder is 1 or 2, a message is displayed on an operation display part (S103), and whether or not the signature copying is executed is judged (S104). In the case the judged result is NO, either double-sided copying or one-sided copying is selected (S105). Then, copying is started in a selected copying mode (S106 and S107). Since copying desired by a user is executed in the decided mode in such a way, the blank page caused at the time of selecting the signature copying mode is restrained to the minimum.
