Title: Determination of activity of enzyme decomposing s- acylthioester
Inventor: KUROOKA SHIGERU
IPC: C12Q1/44
Filed: 1981-11-26
Abstract: PURPOSE:To enable the automatic determination of the activity of an enzyme without using centrifugal separation, by adding an acidic aqueous solution of an anionic surface active agent to the reaction system containing an enzyme capable of decomposing S-acylthioester, thereby terminating the enzymatic reacttion. CONSTITUTION:A specimen containing an enzyme capable of decomposing S- acylthioester is incubated in the presence of S-acylthioester and a thiol color developing reagent, and the activity of the enzyme is determined by the developed color. In the above process, the enzymatic reaction is terminated by adding an acidic aqueous solution of an anionic surface active agent to the reaction system, and adjusting the pH of the system to 5.8-6.2. The amount of the surface active agent is selected to be sufficient to turn the cloudy liquid to clear. The anionic surface active agent is preferably the one having a sulfate group, especially sodium laurylsulfate, sodium laurylbenzenesulfate, etc. It is not recommendable to use an anionic surface active agent having phosphate group in view of the protection of environment.

Title: Perpendicular magnetic recording medium
Inventor: YOSHINO RYOETSU
IPC: G11B5/667
Filed: 1993-07-30
Abstract: PURPOSE:To obtain a perpendicular magnetic recording medium having high coercive force and ensuring high reproduction output by using a CoCrTaPt alloy film as a recording magnetic layer. CONSTITUTION:An NiFe layer as a backing soft magnetic layer 2 is formed on an Al substrate as a nonmagnetic substrate 1. A CoCrTaPt alloy layer being a recording magnetic layer 3 is formed on the backing soft magnetic layer 2 and a protective layer 4 of carbon is further formed. The reproduction output and high recording density characteristics of a perpendicular magnetic recording medium are considerably affected by the coercive force of the recording magnetic layer, higher coercive force can give higher reproduction output and much higher coercive force can be ensured by adding Pt to CoCrTa. Since the CoCrTaPt alloy is used as the material of the recording magnetic layer 3, high reproduction output and satisfactory high recording density characteristics are ensured without increasing the thickness of the magnetic layer 3.

Title: Clock generating circuit for control circuit of multi-channel receiver
Inventor: ONODERA TETSUO
IPC: H04B15/00
Filed: 1986-08-15
Abstract: PURPOSE:To eliminate the need for a strict shield device between a reception circuit and a control circuit by deviating a clock signal frequency so as to avoid harmonics of a clock signal frequency from being invaded in using a channel onto which the harmonics are invaded. CONSTITUTION:In using 15MHz for a frequency of a clock signal 7 and selecting a reception frequency range of 800-820MHz of a reception circuit 1, since a frequency 810MHz being 54 times the frequency of the signal 7 is invaded in the reception frequency range of the circuit 1, if a channel using 810MHz is received, the channel is subject to disturbance. In this case, the system is preset so as to send a clock frequency switching signal 6 only when the set signal of the channel is sent to activate a switch element S of a frequency switching circuit 4b and to connect a capacitor C thereby varying the oscillated frequency of the clock frequency oscillation circuit 4a. In the multi-channel receiver of the constitution above, the disturbance is not exerted by deviating the frequency by nearly 25kHz. Thus, no tight shield structure between the circuit 1 and a control circuit 2 is required.

Abstract: PURPOSE:To obtain a tight scale steel sheet having high adhesiveness by hot rolling a steel slab contg. C, Si, Mn, B, and Al respectively at prescribed ratios, stipulating respective temp. regions and coiling the steel sheet then subjecting the coil to slow cooling. CONSTITUTION:The steel slab contg., by weight, <=0.10% C, <=1.0% Si, 0.05-1.0% Mn, 0.0020-0.005% B, and <=0.10% Al is treated in the following manner. After the slab is hot rolled, the steel sheet is coiled at >=600 deg.C and is then slowly cooled down to <=300 deg.C. The scale of the coil taken up at said temp. is the single phase of FeO except the surface layer thereof. The transformation to Fe3O4 simultaneously from the Fe3O4 side on the surface of the scale layer and the boundary between the scale and base iron progresses when the coil is slowly cooled. The transformation FeO Fe3O4 from the base iron side is presumed to increase the adhesiveness at the boundary between the scale and the base iron. The steel sheet for working which does not require pickling and bonderizing is obtd. by the above-mentioned treatment.

Title: Apparatus for detecting abnormality in pulse encoder
Inventor: TOKASHIKI MUTSUO
IPC: G01D5/244
Filed: 1988-08-01
Abstract: PURPOSE:To impart detecting functions surely for all abnormal states by obtaining the conjunction and the input nonconjunction of three-phase pulse outputs from a rotary encoder, and detecting the abnormality from the results of the operations. CONSTITUTION:Three-phase pulse signals are inputted into photocouplers 1 - 3. Output voltages V11 - V13 are generated in the photocouplers. An AND circuit 41 obtains the conjunction of all the output voltages V11 - V13 from the photocouplers 1 - 3 and generates an output voltage V14. An input NAND circuit 42 obtains the input nonconjunction by the same way and generates an output voltage V15. An OR circuit 51 generates an output voltage V16 that attains an H level when either of the AND circuit 41 or the NAND circuit 42 outputs an H level. In a pulse encoder which outputs three-phase pulse signals, the three-phase signals do not become positive or negative simultaneously as long as the pulse signals are normal. Therefore, abnormality can be detected surely.
