Abstract: A magnetic sensor includes a magnetic sensor chip that includes a magnetoresistive effect element and a sealed part. The magnetoresistive effect element includes a free layer and a pinned layer. The sealed part has a first surface and a second surface, which is opposite the first surface. The shape of the sealed part in the plan view from the first surface side is substantially quadrilateral. The substantially quadrilateral shape has a first side and a second side, which are substantially parallel to each other. In the plan view, from the first surface side of the sealed part, the magnetization direction of the pinned layer, in a state in which the external magnetic field is not applied on the magnetoresistive effect element, is inclined with respect to an approximately straight line found through the least squares method using a plurality of points arbitrarily set on the first side.

Abstract: A temperature measuring device includes a spin group made up of a group a plurality of particles having spins, and a superconducting quantum bit which detects magnetization of the spin group. The spin group is disposed at an asymmetric position on the superconducting quantum bit. The temperature measuring device also includes a magnetic field application unit which applies a magnetic field to the spin group in a direction horizontal to the superconducting quantum bit, and a measuring unit which measures energy of the superconducting quantum bit.

Abstract: Saccharomyces species FD 612 (FERMBP-742), which has been bred by selective hybridizations, has freeze-resistance and is useful as a baker's yeast in bread production in which a dough is prepared utilizing flour and Saccharomyces species FD 612 as the leavening agent. The dough thus prepared is thereafter frozen, thawed after frozen-storage, fermented, and baked to result in bread of good quality.

Abstract: Colored proteins having a known molecular weight of 1800 to 321200 are prepared by coupling monomers of a colored protein having a known molecular weight or by coupling a colored protein having a known molecular weight with a colorless protein having a known molecular weight. At least two proteins are selected from the so prepared colored proteins and used as a colored molecular weight marker. This colored molecular weight marker is used for determination of the molecular weight of a protein having an unknown molecular weight, and can also be used as a reference protein for purification of a protein having a known molecular weight.

Abstract: A group of compounds having the following general formula can be obtained by reacting chromoprotein and organic acid: ##STR1## wherein X is a chromophore, P is a protein, NH.sub.2 is mainly .epsilon.-amino group of lysine, n is a positive integer of 1 to 18, and m is a positive integer in the relation of m.ltoreq.n. This compound group has one to eighteen organic acids bonded thereto, and shows various isoelectric points in accordance with the number of the organic acids, but the respective isoelectric points are maintained constant. If such compounds each having an individual isoelectric point, are used as isoelectric point markers, it is possible to recognize accurately the position of isoelectric point only by a visual operation.
