Title: Element for dry analysis of alpha-amylase
Inventor: SARUHASHI MASAKUNI
IPC: C12Q1/40
Filed: 1983-09-12
Abstract: PURPOSE:To improve the accuracy for the determination of alpha-amylase, and to simplify the procedure, by arranging an iodine compound and an oxidizing agent in the analyzing element in a manner to enable isolation of iodine corresponding to the contact of the analyzing element with a fluid specimen. CONSTITUTION:Iodine is included in a binder or a microcapsule in the form of a combination of an iodine compound and an oxidizing agent, and iodine is produced in the solid phase. The iodine is arranged on the analyzing element in a manner to effect the diffusion of the iodine slowly to the alpha-amylase-starch reaction zone and develop the color by the formation of an iodine-starch complex when a fluid specimen is dripped to the included iodine. Since the iodine-starch complex is a polymer resistant to diffusion, the chromatographic phenomenon and the nonuniform color development can be suppressed almost completely.

Title: Digital/analog converter device
Inventor: TAMURA MANABU
IPC: H03M1/82
Filed: 1987-07-03
Abstract: PURPOSE:To prevent the runaway, breakage, etc., of various devices caused in a power-on state by using a flip-flop circuit which is preset in an initial state and inhibits the output of a latch circuit. CONSTITUTION:The digital data D11 for device control received from a host device like a computer, etc., is supplied to a latch circuit 11. The data output action of the circuit 11 is controlled by the Q-side output of a flip-flop circuit FF 13 which is applied to an output inhibiting terminal OE. In other words, an integration circuit 17 integrates the power supply voltage Vcc to preset the FF 13 when a power supply is switched on and then fixed the Q-side output and the Q'-side output a '1' and '0' respectively after a fixed period of time. Then the output of the circuit 11 is inhibited when the Q-side output of the FF 13 is equal to '1'. If a control signal S11 is received from the host device under such conditions, the Q-side output of the FF 13 is set at '0' and the inhibition of output of the circuit 11 is released.

Title: Production of high strength galvanized steel sheet excellent in press workability and plating adhesion
Inventor: SUZUKI YOSHITSUGU
IPC: C22C38/18
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of nonplating in a steel sheet contg. a prescribed amt. of reinforcing elements in particular by prescribing the coiling temp. SOLUTION: In this producing method, coiling after hot rolling is executed under the following temp. conditions: the coiling temp. is regulated to 780×[(Si(%)+Mn(%)/10+Cr(%)/10)<0.148> ( deg.C) or above. In this way, the surface layer part of the hot rolled steel sheet is internally oxidized by oxygen dissociated from black coating essentially consisting of iron oxide and covering the hot rolled steel sheet, and as a result, the concentration of the surface is suppressed to prevent the formation of the oxides of Si, Mn and Cr as reinforcing elements on the surface of the steel sheet. Thus, its wettability with hot dip zinc does not deteriorate. Thus, the production of the galvanized steel sheet free from the generation of nonplating and excellent in press workability and plating adhesion is made possible even in the case of a steel sheet contg.  Si, Mn and Cr by >=0.7wt.% in total particularly.
