Abstract: A rotor is provided with: a rotor core (32); a plurality of permanent magnets (33); a substantially tubular magnet cover (71); and a load reception block (70). The rotor core (32) rotates integrally with a rotary shaft of a motor. The permanent magnets (33) are arranged on the outer peripheral part of the rotor core (32). The magnet cover (71) covers the exterior of the plurality of permanent magnets (33) and the rotor core (32), and has a flange part which is bent radially inward at the end along a rotation axis. The load reception block (70) is disposed between the flange part and the end surface of the rotor core (32) in a direction along the rotation axis, and abuts against the flange part and the rotor core (32).

Abstract: The disclosure provides a liquid administering device capable of accurately administering a liquid to a predetermined part in a nasal cavity. A liquid administering device 2 includes a main body 4, a first nozzle 6 that protrudes from the main body 4 in a predetermined direction and dispenses a liquid while being inserted into one nasal cavity 28a of a user, and a second nozzle 8 that protrudes from the main body 4 in the predetermined direction and is inserted into the other nasal cavity 28b of the user to position the first nozzle 6 with respect to one nasal cavity 28a.

Abstract: Provided is a nasal drop device which can simply and easily administer an appropriate amount of a solution to a specific site in the nasal cavity without waste. The nasal drop device 100 includes: an ejection portion 104 that ejects droplets into the nasal cavity; and a control portion that acquires suitability information indicating whether or not a current relative angle between a reference line indicating the posture of the face of a user who puts the nasal drop device 100 in the nose and a reference line indicating the posture of the nasal drop device 100 is suitable for the nasal drop, and controls the ejection operation of the ejection portion 104 according to the suitability information.

Abstract: In a connector attachment structure of an electronic device, an immixture of a noise into a signal line by a static electricity is prevented by using a simple and inexpensive composition. A connector attachment structure (10) is composed of a connector (11), a circuit board (12), a metal chassis (13), a connector setscrew (14), etc., and a metal shielding member (16) is disposed around a terminal (15) of a connector (11). A static electricity discharged to the shielding member (16) can be let off to the chassis (13) through the connector setscrew (14) by connecting the shielding member (16) to the chassis (13) through the connector setscrew (14) electrically, and the immixture of the noise into the signal line can be prevented as well as using an inexpensive-general screw.

Abstract: In a temperature detector a smoother circuit receives a pulse signal generated by a pulse signal generation circuit to smooth the signal and transmit it to a first node. A comparator compares a level in voltage transmitted on the node with that in voltage on a second node connected to a thermistor element line and outputs a resultant comparison as a detection signal to a heater controller. The temperature detector can have on the first node a reference voltage adjustable by a duty ratio of the pulse signal output by the pulse signal generation circuit. A resistor or similar component can be dispensed with and simply by adjusting the pulse signal's duty ratio the reference voltage can be adjusted. Temperature can thus be detected with high precision.

Abstract: An image formation apparatus has a medium storage cartridge mounted in the image formation apparatus and a medium size detection device attached to the image formation apparatus. The medium storage cartridge has a medium back end stopper and a protrusion part. In a state in which the medium storage cartridge is mounted in the image formation apparatus, protruding protrusions of the protrusion part press a medium size detector and the medium size detector makes contact with through holes provided in a substrate and a medium size is detected by voltage states of the through holes.
