Abstract: [Object] To provide a contact that can hold down effects caused by solder, even if an elastic contacting portion is extending from a location contacting a first member. [Solving means] The contact includes a base portion, an elastic contacting portion and a gap forming portion. The base portion is configured solderable on a component mounting surface of the first member. The elastic contacting portion is configured elastically deformable and relatively swingable with respect to the base portion, and when contacting a contacted surface of the second member, is configured to elastically deform to be in pressurized contact with the contacted surface. In the gap forming portion, a concave portion is provided between a first end portion and a second end portion, and is configured to have a gap between the concave portion and the component mounting surface when the base portion is soldered on the component mounting surface in a state in which the concave portion and the component mounting surface are oriented in directions facing each other.

Abstract: A noise suppression member comprises a magnetic core and a case that houses the magnetic core therein. The case comprises a first housing and a second housing that form a housing space to house the magnetic core; a locking mechanism that allows the first housing and the second housing to be fixed to each other through engagement of a claw with a claw receiver; and a support receiver. The claw receiver comprises a movable portion displaceable to a first position and a second position, and the claw is released from the claw receiver when the movable portion is displaced to the second position. The movable portion is nondisplaceable to the second position when the support is inserted into the support receiver.

Abstract: Object:To provide a pressure sensor that can provide a reduced sensation of a foreign body and that has a good sensitivity to pressure from a low load region to a high load region.Resolution means:The pressure sensor includes a variable resistor and a plurality of electrodes. The variable resistor is made of an electrically conductive foam elastomer material. The electrically conductive foam elastomer material is a material imparted with electrical conductivity by dispersing electrically conductive fillers into an elastomer material and obtained by foaming the elastomer material. The plurality of electrodes are disposed at intervals from each other on one surface in contact with the variable resistor.

Abstract: A noise suppression member according to one aspect of the present disclosure includes: a first core part and a second core part; and a first case part and a second case part. The first case part and the second case part are provided with engagement mechanisms. The engagement mechanisms each include an engaging portion and an engaged portion and is configured to fix the first case part and the second case part by engaging the engaging portions with the respective engaged portions. When the first case part and the second case part are fixed with the engagement mechanisms, the first core part and the second core part are maintained in a state of forming an annular magnetic core. When the engaging portion engages with the engaged portion, the first core part and the second core part are configured to come into contact with each other.

Abstract: An object is to provide an output-noise reduction device that can prevent noise from an electronic device accommodated in a metal casing from being transmitted due to electromagnetic coupling. An output voltage is extracted to the outside through a conducting bar. A magnetic body core includes a through hole through which the conducting bar is inserted. A chip capacitor is mounted on a mounting board and connects between the output terminal VO and ground potential. A section from the output terminal VO to at least part of the chip capacitor mounted on the mounting board is isolated from the electromagnetic coupling from the electronic device. Thus, noise is prevented from being transmitted to the output terminal VO.
