摘要:
A relay device (30) receives a standard radio wave transmitted from a transmitting station (10) and containing time data, i.e. a time code. The device (30) transmits a relayed radio wave containing the time code received, at a first intensity. When the device (30) receives a transmission command code transmitted from a time-data receiving apparatus (50), it transmits the relayed radio wave for a predetermined time (10 minutes) at a second intensity that is lower than the first intensity. When a time-correction switch is operated, the time-data receiving apparatus (50) transmits a transmission command code to the relay device (30). The time-data receiving apparatus (50) receives the relayed radio wave transmitted at the second intensity from the relay device (30) in response to the command code and corrects the time on the basis of the time code it has received.

A method of forming a coating on a polyolefin substrate comprising the steps of applying a primer coating onto the substrate and then applying a finish coating is disclosed. The method is characterized in that the primer coating consists essentially of a polyurethane prepolymer derived from a polypropylene glycol having a molecular weight from about 400 to about 2,000 and an excess of diphenylmethane diisocyanate.

According to an embodiment, two or more sets of knead forging are performed where one set is cold forging processes in directions parallel to and perpendicular to a thickness direction of a columnar titanium material. The titanium material is heated to a temperature of 700° C. or more to induce recrystallization, and thereafter, two or more sets of knead forging are performed where one set is the cold forging processes in the directions parallel to and perpendicular to the thickness direction. Further, the titanium material is cold rolled, and is heat-treated to a temperature of 300° C. or more.

A radio wave timepiece includes: a display unit, a display drive unit, a receiver unit and a control unit. The display unit displays a current time in a digital manner. The display drive unit drives the display unit by a drive signal of a predetermined drive waveform frequency. The receiver unit is capable of receiving radio waves of a plurality of different frequencies including time information. The control unit sets the drive waveform frequency during the reception of a radio wave by the receiver unit so that harmonic frequencies with respect to the drive waveform frequencies can be different from a receiving frequency of the radio wave.

An electronic device includes a circuit substrate, an antenna, an electronic component or a terminal, and a shield pattern. The antenna includes: a core having a length direction; and a coil part including a conducting wire wound around the core, and is disposed on a first side of the substrate in such a way that the length direction is nearly parallel to the first side. The electronic component or the terminal is disposed on a second side of the substrate in such a way as to correspond to the antenna. The shield pattern is disposed on and/or in the substrate between the antenna and the electronic component or the terminal. The length of a part of the shield pattern, the part overlapping with the antenna, is shorter than the length of the coil part.

A magnetic resolver includes a stator core made of magnetic material, coils, and a rotor. The stator core has a base plate and protrusions formed integrally with the base plate so as to protrude from a surface of the base plate in the thickness direction. The coils are provided around the respective protrusions. The rotor is disposed so as to face the surface of the base plate with the coils interposed therebetween. The overlapping area between the rotor and each of the protrusions changes with a change in a rotation angle of the rotor relative to the stator core. The stator core has through-holes that pass through the base plate and the respective protrusions in the thickness direction.
