Abstract: An electromagnetic relay includes a movable iron core arranged to move up and down within a center hole of an electromagnet unit formed by winding a coil, and a contact switch where an upper end surface of the movable iron core attaches to and detaches from a lower end surface of a fixed iron core arranged in the center hole according to magnetization and demagnetization of the electromagnet unit and a movable contact attaches to and detaches from a fixed contact by a movable shaft which reciprocates along with the movable iron core where the movable iron core includes a sliding portion which always abuts an auxiliary yoke disposed within a yoke, and where a height dimension of the sliding portion is at least equal to or larger than a plate thickness dimension of the yoke.

Abstract: A deposition detection circuit (3) provided in a deposition detection device (1) includes a determination circuit (4) determines whether the movable contact (9) is deposited based on a step input signal and a transient response signal when a drive signal is in an off state. The transient response signal is generated so as to correspond to voltage less than or equal to operating voltage of the electromagnetic relay switch (5) according to an excitation coil (6) and a fixed resistor (R1).

Abstract: A unit for controlling one or more electromagnetic relays, each having a contact point and an exciting coil to which rated power is supplied so as to open and close the contact point, has a control circuit which carries out PWM control so as to keep an electromagnetic relay turned on, after turning on the electromagnetic relay by causing rated power to be supplied to an exciting coil of the electromagnetic relay, and a temperature detecting circuit that detects a resistance value of the exciting coil so as to allow the control circuit to calculate a temperature of the electromagnetic relay. The control circuit changes, depending on external information, a controlling value in accordance with which the PWM control is carried out with respect to the electromagnetic relay. The control circuit detects, from the temperature detecting circuit, a voltage corresponding to the resistance value of the exciting coil.

Abstract: A channel chip includes a substrate made of a material capable of transmitting light. The substrate includes a groove to form a channel for allowing a fluid to flow. A film is made of a material capable of transmitting light. The film is bonded to the substrate with a pressure sensitive adhesive agent to seal the groove.

Abstract: An input device, which is small-sized and inexpensive in spite of being simple in construction and thin, comprises at least one primary electrode and a plurality of secondary electrodes, both electrodes being formed in the same plane. A position of a dielectric is identified on the basis of differences in electrostatic capacity between the primary electrode and the secondary electrodes, which electrostatic capacity is changed by the dielectric positioned on a surface side of the both electrodes.
