Abstract: An oscillation device includes a vibrator made of a quartz substrate, a vibration substrate coupled to the vibrator and including a peripheral portion surrounding a periphery of the vibrator, a support substrate jointed to the vibration substrate at the peripheral portion of the vibration substrate, a cap layer disposed on an opposite side of the vibration substrate from the support substrate and jointed to the vibration substrate at the peripheral portion of the vibration substrate via a joint. At least one pad electrically connected to the vibration substrate is formed on the cap layer. At least one conductor pattern opposed to the pad is formed on a vibration substrate side surface of the cap layer and is electrically connected to the pad.

Abstract: A pressure/temperature sensor includes a sensor circuit configured to detect a pressure and a temperature of a measuring medium in a pipe, a holding member configured to hold the sensor circuit to be positioned inside a tube fixed to the pipe, and an introduction portion provided in the holding member to be positioned at an inner side of the pipe with respect to the sensor circuit. The introduction portion includes a plurality of blades having blade surfaces extending along a protrusion direction of the introduction portion with respect to the sensor circuit. The plurality of blades are arranged radially on a perpendicular surface perpendicular to the protrusion direction, and angles defined by the blade surfaces of the adjacent blades are all acute angles.

Abstract: Within a housing portion in which a recessed portion is formed, a circuit board is arranged on the bottom surface of the recessed portion, through a first connecting member. An acceleration sensor is stacked on the circuit board, through a second connecting member. Hence, sections that function as three or more springs, i.e., an anti-vibration portion, the first connecting member, and the second connecting member, are situated between an angular velocity sensor and the acceleration sensor. For this reason, transmission of vibration of the vibrating element in the angular velocity sensor to the acceleration sensor can be restricted, and reduction in the detection accuracy of the acceleration sensor can be restricted.

Abstract: The present disclosure provides a pressure sensor configured to generate an electrical output according to a fluid pressure in a detection space applied to a diaphragm. The diaphragm is flexibly deformable in a thickness direction. The pressure sensor includes a pressure receiving recess defining the detection space and a protection film covering the pressure receiving recess. The protection film has a corner portion provided in an inner corner area of the pressure receiving recess. The corner portion is located outside the diaphragm in an in-plane direction orthogonal to the thickness direction.

Abstract: A sensor device has a gyro sensor and an acceleration sensor. The gyro sensor has a fixed base portion formed in a rectangular frame shape. The acceleration sensor is formed in an inside space of the fixed base portion of the rectangular frame shape. The gyro sensor is formed in an outside space formed between the fixed base portion and an outer frame portion of a sensor base plate. The gyro sensor and the acceleration sensor are formed in one chip. As a result, the sensor device can be made smaller in size.

Abstract: A refrigeration cycle device includes a compressor, a radiator, an expansion valve, an evaporator and a controller controlling an opening degree of the expansion valve. The controller determines an increase/decrease amount of the opening degree of the expansion valve, to a first amount, when a superheat degree of the refrigerant flowing out from the evaporator is equal to or lower than a predetermined superheat degree. In addition, the controller determines the increase/decrease amount of the opening degree of the expansion valve, to a second amount that is set to more suppress an increase of the superheat degree of the refrigerant flowing out from the evaporator, than that of the first amount, when the superheat degree of the refrigerant flowing out from the evaporator is higher than the predetermined superheat degree.
