Title: Method for acclimatizing microorganism of biological deodoration column
Inventor: OGOSHI YOSHIO
IPC: B01D53/34
Filed: 1992-02-28
Abstract: PURPOSE:To shorten the time for acclimatization and to surely execute acclimatization at a high degree at the time of acclimatizing microorganisms for decomposing odorous components by passing the low-concn. odorous gases discharged from the aeration tank of sewerage-treatment facilities through a biological deodorization column packed with packing materials to serve as microorganism carriers prior to a biological deodorization treatment in the biological deodorization treatment of these odorous gases. CONSTITUTION:The waste gases of the aeration tank are mixed with the high-density odorous gases generated from the sludge treatment device of the sewerage-treatment facilities and the gaseous mixture is passed into the biological deodorization column where the gases are acclimatized. As a result, the acclimatization is surely perfected in a short period of time by incorporating the high-density odorous gases contg. easily biologically decomposable hydrogen sulfide and methyl mercaptan at a high concn. into the waste gases. The stable and efficient biological deodorization is thereafter executed by passage of only the waste gases of the aeration tank. The biological deodorization is easily executed simply by additionally installing a duct piping for the high-concn. odorous gases.

Title: Vertically magnetized recording head
Inventor: KOBAYASHI KAZUO
IPC: G11B5/29
Filed: 1985-03-04
Abstract: PURPOSE:To eliminate the effects of an external vertical magnetic field by giving the magnetic anisotropy to each main magnetic pole of two unipolar magnetic heads put on a single slider in the direction tilted previously from the width direction of the main magnetic pole. CONSTITUTION:The magnetic anisotropy is given to both main magnetic poles 41 and 42 with a slight shift given toward an arrow E against the width direction D of each magnetic pole so that an interaction is eliminated between both magnetic poles. Thus the unbalanced effects of a magnetic field can be corrected. Then a Hall element or a sensor element like a magneto-resistance element, etc. and an energizing coil which eliminates an external magnetic field are attached to a unipolar vertical magnetic head for rigid disk. The sensor element detects an external vertical magnetic field, and a current is supplied to the energizing coil to produce a magnetic field that can eliminate the external vertical magnetic field. Thus it is possible to eliminate easily with good balance the effects of an external vertical magnetic field.

Filed: 1986-02-28
Abstract: PURPOSE:To increase the film growth speed and to reduce the temperature coefficient of the Faraday rotation angle by forming a Bi substituted single crystal garnet thin film containing Tb on a nonmagnetic garnet single crystal substrate by the liquid phase growing method. CONSTITUTION:A Farady rotator 2 consists of a nonmagnetic garnet single crystal substrate 3 and this films 4 which are formed on both faces of the substrate 3 by the liquid phase growing method and consist of a Bi substituted single crystal garnet (for example, (TbBi)3Fe5O12) containing Tb.

The current efficiency for deposition of tin is thus made about <=60%. The Cr hydroxide is peeled and the Cr plating surface is activated by decreasing the current efficiency, by which the good surface appearance and uniform coating of tin are obtd.

Title: Oscillating circuit
Inventor: SAGA RIYOUHEI
IPC: H03K4/501
Filed: 1981-03-27
Abstract: PURPOSE:To achieve stable oscillation even at a low voltage, by inputting a charging/discharge voltage to a parallel circuit of a resistor and a capacitor at the input side of a Schmitt trigger circuit, through the on/off control of a transistor (TR) feeding the output of a Schmitt trigger circuit back to the input. CONSTITUTION:An output of a Schmitt trigger circuit 1 is fed back to the input side via a TRQ3. When an input Vin is at high level, a TRQ1 is conductive. A TRQ2 is nonconductive and a current I1 flows to an emitter resistor RE to produce a voltage drop of RE.I1. To turn off the TRQ1, the input Vin should be smaller than VBE1+REI1. When the TRQ1 is nonconductive, a voltage drop of RE(I1+I2) is produced at an emitter resistor RE, where I2 is the collector current of the TRQ2. To turn on the TRQ1, the input Vin should be higher than{VBE1+RE(I1+I2)}. Thus, two stable points of VBE1+REI1 and VBE1+ RE(I1+I2) are produced in the input Vin, and oscillation is made with transit between the two stable points.

An LB film 33 is provided in recesses of the grating part of the LB film 31, and the LB film 31 and LB film 33 are in level with each other, thereby forming a plane type, i.e. phase difference type grating 36. Further, the LB films 31 and 33 have the same surface property. When the surface of the LB film 31 is hydrophilic, the surface of the LB film 33 is also made hydrophilic. When the surface of the LB film 31 is hydrophobic, on the other hand, the surface of the LB film 34 is also made hydrophobic. A reflecting layer 35 is formed by vapor-depositing an Al film. The film thickness of the LB film 34 is so set that light 36-b which is diffracted by the grating and projected directly on the substrate side 32 and light 36-a which is projected on the LB film side 34, reflected by a reflecting layer 35, and projected on the substrate side 32 interfere with and intensify each other. In this case, an LB film 34 functions as a buffer layer. The projection light beams 36-a and 36-b intensity each other when their optical path difference is an integral multiple of the wavelength.

Abstract: The elevator (E) cyclically passes through the seats (S) of a feeding disc (D), to transfer a caramel (P) and wrapper (T) to the station where said wrapper is to be sealed. The stem (2) of the elevator is inclined so that, during the lifting movement of the elevator, it moves relatively with respect to the seat (S) through which it passes in the same direction (F) of the operational rotation of the feeding disc (D). Thus, the feeding disc may go on operating, not only during the return or lowering stroke (X3), but also during the lifting stroke of the elevator.
