Title: Positioning servo device of magnetic head
Inventor: SUGIMOTO YUKIMASA
IPC: G11B21/10
Filed: 1985-05-27
Abstract: PURPOSE:To realize doubling the track density by using a stepping motor of the disc device itself to position a head and to write servo information thereby eliminating the need for an expensive positioning device and simplifying the position deviation correction control. CONSTITUTION:A head 1 faces respectively four data storage faces of two discs 26, the head 1 is positioned in one phase exciting state by using the head 1, a moving mechanism 29 and a stepping motor 18 to record alternately servo information A and B. A servo sector 31 is placed just after the reference position by a position detector 7, a data track is set to a position where the information A in the one phase exciting state and the information B in the 2-phase exciting state have equal amplitude in the read signal and the position corresponds to the state flowing a different current to 2-phase windings of the motor 18. Then a servo control circuit 23 positions the head 1 just above the center line of the track. In this case, the current value applied to the winding of the motor 18 is adjusted based on the motor 18.

Title: Microwave proximity switch
Inventor: TAKINAMI KOJI
IPC: G01S13/04
Filed: 1988-05-12
Abstract: PURPOSE:To certainly detect a stationary body even when said body is present at any position, by using a drive signal having two or more different voltage levels in driving to transmit two or more different frequencies and subjecting different phase differences to level discrimination. CONSTITUTION:A drive signal having a waveform wherein different voltage levels V1, V2 appear alternately at a definite cycle is inputted to a microwave oscillator 12 and also inputted to the input terminal of a differential amplifying circuit 16 as a reference signal. The oscillator 12 generates a microwave of frequency f1 at the time of voltage V1 and a microwave of frequency f2 at the time of voltage V2. Each of the oscillated microwaves is transmitted toward the detection region of a body 30 through a transmitter-receiver 14 and a mixer 13 mixes the microwave signal, which is returned from the body 30 and received by the transmitter-receiver 14, with the oscillation output of the oscillator 12. An amplifying circuit 15 amplifies the output of the mixer 15 to the level of a reference signal and the differential amplifying circuit 16 amplifies the difference between the mixer output through the circuit 15 and the reference signal. A comparator 17 compares the output signal of the circuit 16 with the voltage of a threshold value level given from an adder circuit 20 and transmits an H-level signal to an integrating circuit 18 when said output signal exceeds the threshold value level.

Abstract: PURPOSE: To improve the yield of non-yeast protein by culturing a clone group of the heat host transformed with a specific expression cassette.  
     CONSTITUTION: A fragment including ADRI gene is obtained by cleaving the plasmid YPp7-ADRI-411 including the gene of yeast ADRI (yeast-originating glucose-repressible alcohol dehydrogenase II) with a restriction enzyme Hinc II. Then, this fragment is ligated, and subjected to enzymatic treatments to prepare an expression cassette enhancing the expression of ADRI. The cassette is inserted into a yeast vector to form a plasmid pHS119. A yeast host as strain AB110 is transformed with this plasmid and the transformant is cultured in a medium to produce non-yeast protein under control of the ADH2 sequence in the host cells.
