Abstract: A rotation angle detection device that detects a rotation angle of a valve body. The rotation angle detection device includes a shaft, a gear, a magnetic field generator, and a magnetic detection element. The shaft is connected to the valve body. The magnetic field generator is arranged on a gear side and generates a magnetic field. The magnetic detection element is arranged on an extension of the shaft and detects magnetic flux density of the magnetic field that rotates together with the gear.

Abstract: A hands-free telephone apparatus which supports a user so as not to restrict the functions of the hands-free telephone processor. The hands-free telephone processor inquires the state of the mobile telephone when the model of the connected mobile telephone is unknown. If the hands-free telephone processor receives the notification of the state of the mobile telephone in response to this inquiry, the hands-free telephone processor refers to the warning information stored in advance. The hands-free telephone processor determines whether the mobile telephone is in a state of restricting the functions of the hands-free telephone apparatus available to the user. If it is necessary to output a warning, the hands-free telephone processor outputs the warning message registered corresponding to the state of the mobile telephone in the warning information. The hands-free telephone processor issues a restart command to the mobile telephone to restart the mobile telephone.

Abstract: The curable composition for coating of the invention comprises (A) 100 parts by weight of an epoxy group-having resin, (B) from 0.001 to 100 parts by weight of a carboxyl group-having compound or resin, and (C) from 1.0 to 100 parts by weight of a silicon compound of the following general formula (I) and/or its partially-hydrolyzed condensate: (R1O)4-aSiR2a  (I) wherein R1 represents a hydrogen atom, an alkyl group having from 1 to 10 carbon atoms, an aryl group having from 6 to 10 carbon atoms, or an aralkyl group having from 7 to 10 carbon atoms; R2 represents an alkyl group having from 1 to 10 carbon atoms, an aryl group having from 6 to 10 carbon atoms, an aralkyl group having from 7 to 10 carbon atoms, or an alkoxy group having from 1 to 10 carbon atoms; and a represents an integer of from 0 to 2.

Abstract: A speed reduction gear including a semicircular control gear is provided coaxially with a motor shaft between a motor and a throttle valve. A connecting lever which has a valve opening contact and a valve closing contact is secured to a shaft of the throttle valve. When the control gear turns in the valve closing direction, it engages with the valve closing contact, and the throttle valve is closed. A safety stopper and its actuator are also provided. When the control gear turns in the valve opening direction while the stopper is driven by the actuator to extend in the path of the control gear, the control gear is prevented from further turning in the valve opening direction. When a cruise control switch is turned on, the stopper is retracted by the actuator from the passage and the gear turns in the valve opening direction until it abuts the valve opening contact of the connecting lever, which opens the throttle valve.
