Patent JP-S61209743-A (JP)
Title: Production of collapsible core
Inventor: TOYODA TATSUO
IPC: B22C9/12
Filed: 1985-03-13
Abstract: PURPOSE:To form the entire part of a core into homogeneous structure and to provide uniform strength thereto by immersing the entire part of refractory particles into a heat resistant intergranular binder consisting of an aq. aluminum phosphate having a specific concn. then dehydrating the same and executing the molding and drying of the core respectively at specific temps. CONSTITUTION:The refractory grains consist of silica sand, alumina, zircon sand, molten silica, etc. The entire part of the refractory granules is immersed in the heat resistant intergranular binder consisting of the aq. soln. of 7.5-12.5wt% aluminjm phosphate so that the particles are uniformly wetted with the soln. The particles are thereafter dehydrated and the core is press- molded or blow-molded by a metallic mold at 50-250 deg.C temp. The molding is then dried at 300-600 deg.C to remove the moisture, by which the core is manu factured. The core is therefore provided with the structure homogeneous over the entire part and the design of the strength uniform over the entire part is made possible. Since no org. materials are used at all, the need for a heat treatment of a high temp. to burn the org. materials is eliminated and the stage is simplified. The cost of energy and the cost of the core production are thus reduced.

Title: Fructose sensor
Inventor: MIYAHARA MARIKO
IPC: G01N27/28
Filed: 1993-03-12
Abstract: PURPOSE:To quickly measure the fructose concentration of a sample liquid without using any liquid except the sample liquid by uniting the reactive sections of electrodes with reactive sections of enzyme, matrix, and electron acceptors on a substrate. CONSTITUTION:An electrode system (measuring electrode 4 and counter electrode 5) and insulating layer 6 are successively formed on an insulating substrate 1. Then a carboxymethylcellulose(CMC) layer is formed by dropping CMC onto the electrode system as a hydrophilic polymer and drying the polymer. When a mixed solution of an enzyme and electron acceptor is dropped onto the CMC layer, the CMC layer is once melted, is mixed with the enzyme, etc., and forms a reactive layer 7 during the succeeding drying process. However, the surface of the electrode system is coated with the CMC only. When an aqueous solution of fructose is supplied 10 as a sample solution to the layer 7, the aqueous solution is quickly brought to an air hole 11 section by a capillary action and the layer 7 dissolves in the aqueous solution. When a pulse voltage is applied for a fixed period of time across the electrode 4 toward the anode by using the electrode 5 as a reference after supplying the sample solution, a response current value is obtained proportionally to the fructose concentration of the sample solution.

IPC: H04M11/00
Filed: 1991-03-18
Abstract: PURPOSE:To allow a communication equipment to receive a signal correctly even when the signal is a low level signal. CONSTITUTION:A current detection section 6 is connected between a 2nd line connection terminal 3 and a 2nd telephone set connection terminal 5 in series and a high voltage signal passing section 7 whose impedance gets higher when a voltage between a 1st telephone set connection terminal 4 and the 2nd telephone set connection terminal 5 is a prescribed voltage or below and an incoming signal bypass section 8 are connected in series. Thus, an incoming signal of a current detection section 6 and hook-off of a communication equipment 9 are detected by using the same circuit and when the communication equipment is in the hook-off state for the communication, the impedance of the high voltage signal passing section 7 gets higher. Thus, the effect of the communication equipment 9 onto the line termination impedance is lost and the line terminal equipment 1 able to receive a signal correctly by the communication equipment 9 is obtained even when the signal is a low level signal.
