Title: Microorganism assay and equipment therefor
Inventor: KIKUCHI MOTOKAZU
IPC: C12M1/34
Filed: 2002-08-22
Abstract: PROBLEM TO BE SOLVED: To provide a microorganism assay that can simply and promptly assay fine colonies with high accuracy at small cost in no use of any color coupler and to provide an equipment therefor. SOLUTION: A specimen is scattered on the surface of a flat culture medium and cultured for a prescribed time to assay the microorganism colonies developed thereby. A band of the assaying area that crosses the flat culture medium is set and at least a couple of band lights are injected at an angle so as to nip the assay area with the couple of the band lights. As the reflection light of the injected light band is received with an image picking means, the flat culture medium is allowed to move relatively to the assay area thereby forming two dimensional image. Then, the two-dimensional image is used to assay the presence or absence of microorganism colonies or count the number of the colonies.

Abstract: <P>PROBLEM TO BE SOLVED: To omit the feedback winding of a wire-wound transformer and accomplish size reduction of the wire-wound transformer.  <P>SOLUTION: A drive circuit is connected with direct-current power input portions 12a and 12b, and the wire-wound transformer 10 is connected with the drive circuit. In the drive circuit, switching elements are turned on and off, according to feedback signals of a primary resonance voltage induced in the input-side primary winding of the wire-wound transformer. The direction of the supply of direct-current power to the wire-wound transformer is inverted by this turn-on/off, and the power is inputted to the input-side primary winding of the wire-wound transformer 10 as an alternating-current signal. A phase- detecting means detects the phase of the primary-side resonance waveform of the wire-wound transformer 10 and outputs a phase signal. A phase difference signal generating means converts a single output signal from the phase detecting means into two phase signals, which are opposite in phase to each other, and outputs the signals as driving signals for controlling turn-on/off of the switching elements.  <P>COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To provide a method for friction stir welding capable of excellently welding having a light weight. SOLUTION: The face plates 11 and 12 of a hollow profile 10 are made to abut on the face plates 21 and 22 of a hollow profile 20. A projection 28 of the face plates 21 and 22 is fitted in a groove 18 of the face plates 11 and 12 at an abutting part. A connection plate 14 is orthogonal to the face plates 11 and 12. No connection plate which is orthogonal to the face plates 21 and 22 is provided in the end part of the hollow profile 20. Although the face plate 21 (22) is prone to move in the thickness direction of the hollow profiles 10 and 20 by heat of the friction stir welding, the moving is restrained by the groove 18 and the projection 28. As a result, the abutting part can be welded so as to be flat. The hollow profile 20 can eliminate a connection plate corresponding to the connection plate 14 and can be reduced in weight.
