Title: Urea selective adsorbent
Inventor: MIYAMOTO YASUO
IPC: B01J47/12
Filed: 1980-04-03
Abstract: PURPOSE: To well maintain initial pH of circulating liquid by allowing a weak basic anion exchange resin to coexist in an adsorbent consisting of a strong acidic cationic exchange resin and a strong basic anion perm selective membrane.  
     CONSTITUTION: An adsorbent A is interposed in the flow passage for the liquid to be treated such as blood dialysis liquid, blood or the like contg., for example, urea, metallic ions, etc. The transmission of a greater part of the metallic ions of the liquid to be treated is blocked by the strong basic anion permselective membrane (a), but part of a slight amount of Na + , K +  transmit therethrough together with Cl -  and particularly relatively a large amount of urea is allowed to pass therethrough. The liquid past the membrane (a) contacts the granular sulfonic type strong acidic cation resin (b) and urea is substituted and adsorbed with and by this, but Na + , K +  are also adsorbed and the H +  of sulfonic groups is freed to the liquid side. Here, a primaryWtertiary amine type anion exchange resin (c) is allowed to coexist and therefore said H +  binds with the OH -  released from the resin (c) by exchanging with said intruding Cl -  and is thereby neutralized.

Title: Detecting method for quality deterioration of concrete by freezing and thawing
Inventor: ISHIDA HIROSHI
IPC: G01N17/00
Filed: 1980-04-03
Abstract: PURPOSE:To detect quality deterioration of a concrete in a brief period of time with a small-scale testing device by using a thin piece of concrete exposing an aggregate as a test piece. CONSTITUTION:A test concrete piece T having a size 10X10X40cm in length, width and depth which is generally used as a sample for freezing and thawing tests, is cut to the thickness of 1-2cm on one side. Thus said test piece can be served as one for detecting a progress of quality deterioration inside a concrete through observation, etc. At the same time, because of its thin piece form, it can be judged quickly whether said piece can be durable against freezing damage. With this test piece used, fresh water freezing/thawing tests are conducted and as a result, a quality deterioration which has started on a contact surface between aggregate and mortar inside a concrete is observed at 30 cycles. Submerged tests in the sea water reveal that the test piece has been seriously degraded. In addition, a concrete collapses to pieces at the increased number of cycles for freezihg and thawing and thus is can be used as a test sample for acceleration tests.

Title: High speed parallel communication system
Inventor: MORISANE EIJIRO
IPC: H04J3/00
Filed: 1990-02-23
Abstract: PURPOSE:To attain transfer of lots of data at high speed by adding 3 control lines so as to send/receive lots of data within a constant time corresponding to multi-bit processing in the bus width of the equipment. CONSTITUTION:Three control lines A-C, in the case of, e.g. 32-bit bus width are added to a conventional parallel communication system. That is, the control lines A-C are connected to a CRT 2 being an output device (receiving side) from a camera 1 being an input device (sender side) similarly to the case of data buses. Then three ways of significance of a signal representing which byte is valid in the data bit width and a transfer rate generated by the device sending the data and the transfer start timing are integrated for the use of the control lines. The parallel communication system of 8-bit data width in a conventional system is expanded into 32-bit data width in time division by adding the three control lines A-C and when the receiver side equipment is designed to be 32-bit data width, the system copes with all the bit data width of 8, 16, 32-bits. Thus, the high speed performance of the parallel communication system is much more enhanced.

Abstract: PROBLEM TO BE SOLVED: To reduce the quantity of load to be required for dynamic load distribution and to improve the efficiency of processing by executing dynamic load distribution so as to request task allocation to another processor after judging that a certain processor can not process a request task newly generated in the processor itself. SOLUTION: When a task generation request is generated in a certain processor, the processor executes practicability/impracticability judgement for the task based upon load information and task information (1). At the time of judging impracticability, the generated request task information 15 transmitted to all other processors by a broadcasting function (3). A receiver candidate receiving the task information judges whether it has qualification for substituting the processing of the task or not based upon the load information, at the time of judging it as a qualified processor, transmits the judged result to all other qualified processors by a multi-casting function. Each qualified processor judges qualification based upon the judged results of all the qualified processors and determines a receiver. Then task allocation is requested to the determined receiver (6).
