Abstract: In order to ensure isolation between a plurality of antenna elements arranged in a narrow space while reducing a size of an antenna device for a vehicle, an antenna device (100) for a vehicle includes an antenna case (101), a base (102) forming an accommodation space together with the antenna case (101), and a first antenna element (122) and a second antenna element (123) that are accommodated in the accommodation space. The first antenna element (122) and the second antenna element (123) at least transmit or receive radio waves in different frequency bands. The first antenna element (122) at least partially has a meandering shape in a first direction that intersects polarization of radio waves transmitted or received by the second antenna element (123).

Abstract: The phase of laser light is modulated by a phase modulating array, and a hologram image is projected on a rotating screen. Light emission of the laser light is driven by PWM modulation so that a light emission period and a non-light emission period following the light emission period are repeated. In a case where the luminance of the hologram image is changed, the duty ratio of the light emission period is changed. In a case where the luminance is significantly reduced, the light emission intensity of the laser light is reduced without changing the duty ratio. Since the duty ratio is not reduced, a light diffusion condition on the rotating screen can be randomized even in a case where the luminance is reduced.

Abstract: The present invention relates to a high-reliability vehicle mounted device control apparatus capable of making a decision about functions of switch units with a simple structure and at a high processing speed and a low cost. Each of the switch units comprises a circuit substrate having a required circuit pattern formed to include a plurality of pairs of short-circuiting possible land portions, and a switch mounted on the circuit substrate so that any one of the plurality of pairs of land portions are short-circuited selectively to set a switching function inherent to that switch unit. Any one selected from the switch units is mounted in one of the unit mounting sections, and the switch of that switch unit is turned on. A switch unit decision section constituting a control section detects the land portions short-circuited to automatically make a decision about the kind of a switching function of the mounted switch unit.

Abstract: The motor driving apparatus comprises a plurality of motors for displacing the position of the control object member, semiconductor switch pairs, a plurality of motor driving units for connecting the motors to the power supply and a control unit for ON/OFF controlling the semiconductor switch pairs. The motors form two sets of motors with each set being formed of two motors. One end of the motors and forming each set is connected to the common motor driving unit having the semiconductor switch pair and the other end of the motors and forming each set is connected to the motor driving units having the semiconductor switch pairs in each set. When the motors of each set are driven simultaneously, the control unit turns ON and OFF two semiconductor switch pairs and drives the motors of each set on the time division basis to provide inverse output polarities of the two semiconductor switch pairs connected to the motors of each set.
