Abstract: The disclosure discloses a printer including a printing head, a DC motor, an energization control part, a short-circuiting device, a temperature detecting device, and a braking control part. The DC motor is configured to generate a driving force for feed by a feeder. The energization control part is configured to control energization by an energizing device. The short-circuiting device is configured to short-circuit a positive electrode and an negative electrode of the DC motor and brake when deenergized under control of the energization control part. The temperature detecting device is configured to detect a temperature of ambient surroundings. The braking control part is configured to control the short-circuiting device in accordance with the temperature detected by the temperature detecting device, to thereby variably control an operation mode of the braking by the short circuiting.

Abstract: A thermal detector includes a fixed part, a thermal detection device, a supporting member, a cavity and a connection portion. The supporting member has a first plane and a second plane opposing to the first plane. The cavity is formed between the first plane and the fixed part. The connection portion connects the supporting member with the fixed part. The connection portion includes a curvature plane between the supporting member and the fixed part and the curvature plane facing the cavity.

Abstract: A method for manufacturing a MEMS device having an undercut shape formed on a fixed part includes a first step of forming an etching layer having a first cavity on the fixed part; a second step of forming a mask layer on a side wall of the etching layer, the side wall facing the first cavity; and a third step of directing an etchant fed into the first cavity on a surface side of the mask layer to a back surface side of the mask layer, isotropically etching the etching layer, forming a second cavity communicated with the first cavity on the back surface side of the mask layer, and processing the etching layer into an undercut shape.
