Abstract: In order to suppress deformation of a flexible substrate, a deposition method according to an embodiment of the present invention includes pre-treatment of exhausting a vacuum chamber until a water partial pressure inside the vacuum chamber becomes equal to or lower than a desired value. Plasma is generated by applying an alternate current (AC) voltage between a first chromium target and a second chromium target, the first chromium target and the second chromium target being arranged inside the vacuum chamber. A chromium layer is formed on a deposition surface of a flexible substrate arranged facing the first chromium target and the second chromium target.

Abstract: A motor includes a rotation shaft, a commutator, power supply brushes, and a brush holder. The brush holder includes an opposing portion that faces an end face of the commutator in an axial direction, a bearing holder, and a diffusion stopper. The diffusion stopper is arranged in a portion of the opposing portion located toward the outer side in the radial direction from the bearing holder and limits the diffusion of abrasion powder of the power supply brushes. The diffusion stopper is projected toward the commutator in the axial direction or recessed in the axial direction.

Abstract: In a one-piece resin component, a plurality of stackable resin portions is resin-molded integrally with a resin housing of a dynamoelectric machine and radially outwardly projects from the resin housing. Each the plurality of stackable resin portions is adapted to be stacked against a corresponding one of a plurality of stackable resin portions of another one-piece resin component that is generally identical to the one-piece resin component.

Abstract: A die cushion pad 13 is divided into four small pads 15 and a large pad 16. With this arrangement, a load applied to an action point of each of the small pads 15 can be equalized by the large pad 16, and an overturning moment arising between the action point and a reaction force point that equates the center of the small pad 15 can be canceled, thereby preventing flexure of the small pad 15. Accordingly, since flexure of the cushion pin and the like can be prevented, there is no risk that the cushion pin is frictioned against the penetrating hole of a bolster, and the lifting operation can be smoothly performed, whereby a higher-accuracy pressing forming operation can be realized.

Abstract: Provided is a method of detecting a target substance by which the target substance can be detected with efficiency and a high sensitivity, and in a simple manner, a target substance detection polymer used in the method, and a method of forming the polymer. The method of detecting a target substance includes the steps of: (A) forming a target substance detection polymer by causing multiple kinds of nucleic acid probes for forming a polymer to react with a binding probe having a region capable of binding to the target substance and a region capable of binding to at least one of the nucleic acid probes in a solution; (B) binding the target substance detection polymer and the target substance; and (C) detecting the target substance detection polymer to which the target substance is bound.

Abstract: A pressing machine 1 includes: a bed 6 on which a die-cushion device 10 is provided; and a bolster 51 provided on the bed 6. The bed 6 has an inner space 61 in which a die-cushion pad 13 of the die-cushion device 10 is lifted up and down. A supporting portion 63 penetrating the die-cushion pad 13 in a lifting direction and supporting a lower surface of the bolster 51 via a carrier 52 is provided in the inner space 61. With this arrangement, since the bolster 51 is supported by the supporting portion 63, the bolster 51 can be prevented from being flexed during a press forming operation, whereby a highly accurate press forming operation can be realized. In addition, since the supporting portion 63 penetrates the die-cushion pad 13, unlike conventional arrangements, the die-cushion pad 13 does not need to be divided, whereby a complication of the arrangement can be avoided.
