Abstract: A radiation-sensitive carrier body directly utilized as a stamper has a glass substrate, a first highly adhesive layer securely adhered to the substrate, a radiation-sensitive layer which discharges a gas component upon being irradiated with a laser beam and which locally forms a protuberance due to the absorbed energy, a second highly adhesive layer securely adhered to the specific material of the radiation-sensitive layer and which deforms in accordance with deformation of the layer, and a metal layer which has a high releasability to allow easy separation from a optical disk substrate material such as an acrylic material when the carrier body is used as a stamper substrate for manufacturing optical disks. A protuberance formed on the carrier body such as a continuous spiral protuberance allows formation of a corresponding spiral groove in the acrylic material, serving as a pre-track into which desired information will be digitally written by a user.

Abstract: An axis of rotation of a bed can be shifted in a direction in which it becomes remote from a floor when the bed is slid parallel to a patient-mounted plane while being swung, in a case where the swing angle is relatively small. The amount of elevation of the bed can be made larger than in a case where the axis of rotation is not shifted. The amount of slide of the bed can be thus made smaller than in the case wherein the axis of rotation is not shifted, in order to obtain a predetermined amount of elevation of the bed. As the result, the horizontal component of slide can be made smaller to thereby making smaller the space in which the bed can be swung and slid.
