摘要:
The present invention relates to a wireless communication system having improved PLL circuits in the RF transmitter and receiver sections. The PLL circuits in the wireless communication system according to the present invention include time constant controllable filters. A series circuit of capacitor and resistor detects turn-on of the power switch for the PLL circuits to generate an output signal to be applied to the filters, thereby controlling the time constant of the filters in the PLL circuits to a lower value than normal for a given time after power-on of the PLL circuits.

To provide an electronic apparatus that can prevent electronic components from being separated from a circuit board.The electronic apparatus 10 includes a circuit board 25, an electronic component 28 mounted on the circuit board 25 via solder balls 26, a cover member 30 mounted on the circuit board 25 so as to surround and cover the electronic component 28 and a convex portion 34 provided at the top plate portion 32 of the cover member 30. The convex portion 34 is deformable to a second state protruding on the circuit board 25 side from a first state protruding in the direction opposite to the circuit board 25 side. When the convex portion 34 is deformed in the second state, the convex portion 34 thus deformed can be made in contact with the top portion 28a of the electronic component 28.

There is provided a liquid crystal display capable of decreasing the number of components and easily carrying out an assembly. When a liquid crystal body 13 is to be attached to an opening 12 of a housing 11, the liquid crystal body 13 is supported and attached to the housing 11 by means of a plate portion 16 provided in parallel with the opening 12 through a wall portion 15 on a back side 11a of the housing 11. In this case, a flexible board 14 drawn from an end face of the liquid crystal body 13 is pulled out of an insertion hole 17 provided on the wall portion 15. For this reason, it is not necessary to provide a holding member in the attachment of the liquid crystal body to the housing as in the conventional art. Therefore, it is possible to decrease the number of components and to reduce an attachment man-hour of the holding member.

A three-dimensional shape measuring apparatus capable of simultaneously obtaining range information and luminance information with high precision, independently of an object. A controller scans slit light, emitted from a laser beam source and shaped by a cylindrical lens, on an object plural times, by mirror surfaces of a polygon mirror, while causing the laser beam source to flash by using a laser beam source driver. The slit light is time-sequentially combined into projection pattern light having plural light stripes, respectively 3-level or more intensity-modulated, and the projection pattern light is projected onto the object. An image processor obtains the range information and the luminance information based on reflection light obtained by image pickup by first and second cameras.

A replaceable ink cartridge has a body for storing the ink; an ink outlet for supplying the ink into a recording head; an air communicating port for communicating with an atmosphere; a peripheral portion around the ink outlet; a peripheral portion around the air communicating port; a seal member for removably sealing the peripheral portion around the ink outlet and the peripheral portion around the air communicating port. The replaceable ink cartridge has a structure that is formed so as to strip the seal member off from the peripheral portions of the ink outlet and the air communicating port in a manner that the air communicating port is opened at first and the ink outlet is opened at second.
