IPC: C12N9/88
Filed: 1982-01-26
Abstract: PURPOSE:To enable the stabilization and purification of a novel alpha-carboxylase- like enzyme, by purifing the enzyme with a buffer solution containing a salt, an acid and thiamine pyrophosphate. CONSTITUTION:Commercially available yeast is mixed with alumina and a phosphate buffer solution, disintegrated by ultrasonic wave in ice bath, and centrifuged. The supernatant liquid is added with 30% saturated ammonium sulfate and centrifuged again. The supernatant liquid is added with ammonium sulfate to attain 40% saturation concentration and centrifuged. A purified enzyme can be obtained by adding a phosphate buffer solution to the precipitate. A developing solution is prepared by mixing Na2HPO4, citric acid, MgSO4, thiamine pyrophosphate, and MnSO4 in the order, and adding pure water to the mixture. The developing solution is added to the above purified enzyme, and introduced into the upstream-type column from its bottom. The desired fraction is collected by a fraction collector.

Filed: 1989-01-20
Abstract: PURPOSE:To efficiently contrive the high speed of an operation by preparing at least two points A and B, dividing the case into when A and B are the same, and another case when A and B are different, specifically processing values indicated by the respective pointers, and adding them to the registers of the pointers.

Title: Attraction device for slicing machine
Inventor: TADERA YOSHIHIRO
IPC: B28D5/02
Filed: 1988-01-21
Abstract: PURPOSE:To effectively remove a sliced preformed product out of a slicing machine without damaging the product by increasing negative pressure to a cylinder by negative pressure control means when the cutting operation of a work by a cutting edge is substantially finished. CONSTITUTION:When a slicing mechanism 5 is moved down so that the cutting edge 13 of a blade 10 is brought into contact with an ingot 3, a cutting work is started. When negative pressure is introduced into a negative pressure passage 32, an attraction pad 29 is brought into close contact with the side face of a sliced preformed product 34 by means of negative pressure so as not to be attracted to the blade 10. When the cutting operation is advanced so that the edge 13 is arrived substantially at the lower end of the product 34, the negative pressure is increased. Thus, an arm 28 is resisted against the elastic force of a spring 31 by the negative pressure in a state that the pad 29 is brought into close contact with the product 34, and a stopper 28c is moved until it is abutted against the end of a cylinder 30. As a result, the product 34 is isolated from the blade 10.

Filed: 1994-02-04
Abstract: PURPOSE:To eliminate a modulation characteristic deviation depending on the operating frequency by obtaining a control signal to make a carrier output and modulation constant from a signal component of a feedback control system used that makes a modulation amplifier section output or a carrier output power constant. CONSTITUTION:A carrier output of an output of a modulation amplifier 52 provides an output of a DC voltage proportional to a carrier output from a smoothing section 82 via a detection section 80, inverts the DC output at an inversion section 84 to control an output voltage of a modulation 58A, and the voltage is used for a power supply voltage of the amplifier section 52. The voltage and a carrier signal being an output of an exciting section 50 are fed to the amplifier section 52, from which an amplitude modulation signal is outputted. Furthermore, and the gain of the amplifier section 52 is controlled by the power supply voltage. Through the constitution above, when the carrier output of the amplifier section 52 is decreased the power supply voltage of the amplifier section 52 in a feedback loop comprising the detection section 80, a smoothing section 82, an inverting section 84 and the modulation section 58A rises to increase the gain thereby restoring the carrier output. Furthermore, when e carrier output rises, since the gain is decreased conversely, the carrier output outputted from the amplifier section 52 is made stable.
