摘要:
A noise-reduced internal gear pump incorporating an inner rotor having an addendum formed by a smooth curve and a dedendum formed by a hypocycloid. The tooth profile of the outer rotor is determined by the following steps. The center Oi of an inner rotor 1 is revolved around the center Oo of the outer rotor so as to form a circle S having a diameter of 2e+t, where “e” is the amount of eccentricity between the inner and outer rotors and “t” is the maximum value of the interrotor clearance between the outer rotor and the inner rotor pressed against it. The inner rotor 1 is rotated on its axis 1/n times while its center Oi makes one revolution in the circular orbit S, where “n” is the number of teeth of the inner rotor. The envelope of the group of the tooth profile-curves of the inner rotor formed by its revolution is used as the tooth profile of the outer rotor.

An inner motor is structured to increase the discharge rate of an internal gear pump by making it possible to freely adjust the eccentricity e between the inner and outer rotors. Each tooth of the inner rotor includes a tooth bottom defined by hypocycloidal curves, an engaging portion to be brought into engagement with the outer rotor and defined by involute curves, and a tooth top defined by a predetermined curve such as a part of a circle or an oval or an epicycloidal curve.

It is an object of the present invention to provide an immunochromatography method capable of measuring a sample in a low concentration range and a high concentration range by setting the measurable range of the sample much wider than the conventional measurable range. The present invention provides an immunochromatography method, which comprises: spreading a test substance, a first labeling substance modified with a first binding substance that binds to the test substance, and a second labeling substance modified with the first binding substance that binds to the test substance, which are in a mixed state, on an insoluble carrier; and capturing the test substance, the first labeling substance, and/or the second labeling substance at a reaction site on the insoluble carrier having a substance having ability to bind to the first binding substance that binds to the test substance, so as to detect the test substance, wherein the first labeling substance is a labeling substance that causes an amplification reaction, and the second labeling substance is a labeling substance that does not substantially influence on the amplification reaction.

In an image processing device, a transfer unit enlarges or reduces the image data at the transfer magnification by performing an enlarging or reducing process on the image data once, when the transfer magnification is equal to or smaller than an upper limit or equal to or greater than a lower limit. The transfer unit also repeats, by a plurality of times, a process of performing an enlarging or reducing process on an image data stored in a first region of a storage unit at a divided-transfer magnification equal to or smaller than the upper limit or equal to or greater than the lower limit and then storing the image data in a second region of the storage unit, when the transfer magnification is above the upper limit or below the lower limit.

The invention presents an optical element with which an optical head can be configured, in which there is little deterioration of the correctional effect when the objective lens shifts, as well as an optical head and an optical recording/reproducing apparatus using such an optical element. The invention also presents a novel optical recording/reproducing apparatus and optical recording/reproducing method. The optical element, includes a first voltage application electrode 13, a first opposing electrode 17 arranged in opposition to the first voltage application electrode 13, and a first phase changing layer 15 arranged between the first voltage application electrode 13 and the first opposing electrode 17. By changing a voltage between the first voltage application electrode 13 and the first opposing electrode 17, a phase that converts plane waves into spherical waves is imparted on light that is incident on the first phase changing layer 15.
摘要:
The quantity of spherical aberration correction is predetermined for each recording plane of an optical disk on which focusing control is performed. Before operating the focusing control, the quantity of spherical aberration to be corrected by an aberration correcting system is set based on an output signal from an aberration correction quantity switching device that corresponds to the type of the optical disk and the recording plane to be subjected to the focusing control. This makes it possible to perform stable focusing control on each recording plane of a multi-layer optical disk with high density by using an objecting lens having a large NA after spherical aberration has been corrected properly.
