Abstract: The present invention is for providing a portable terminal device with improved mechanical strength and rigidity of a case so as to prevent damage of functional parts with respect to bend or twist deriving from a small size and a thin shape of the portable terminal device main body, which comprises a printed board with mounting parts mounted thereon, a lower case with receiving ribs provided corresponding to the arrangement position of the mounting parts for receiving the mounting parts, and a battery case provided below the lower case for supporting deformation of the lower case.

Abstract: A flexible board attaching-connecting device includes a case assembly, formed by incorporating a flexible board 2 in a case 1, and a board assembly formed by mounting a flexible board connector 3 on a printed circuit board 4, and an attaching-connecting operation can be made merely by dropping the case assembly onto the board assembly from an upper side.

Abstract: A button switch wherein switching operation of contact patterns 14 printed and wired on a printed circuit board 13 is performed by pushing a contact member 12 provided on a lower face of a pushing member of the button switch is constructed in such a manner that the above mentioned contact member 12 comprises a rubber piece, electrically conductive films formed on upper and lower faces of the rubber piece, and metal wires embedded in the rubber piece so as to interconnect the electrically conductive films, the obtained contact member 12 being bonded to the pushing member.

Abstract: A portable terminal device, capable of improving the releasing property of fitting pieces of an upper case and a lower case at the time of disassembling the appliance, and lowering generation of deformation or crack of the main body by bend or twist while maintaining a sufficient fitting holding force. In the main body of the portable terminal device, a plurality of fitting pieces are provided each in an upper case and a lower case for holding and fixing with each other. The fitting pieces have a fitting horizontal surface to be substantially parallel for holding with each other when the upper case and the lower case are engaged. A part of the fitting horizontal surface of the fitting pieces of at least one of the upper case and the lower case has a fitting twisted surface twisted in the direction away from the fitting horizontal surface of the other fitting piece in the fitting pieces.

Abstract: The structure of the present invention includes a flexible printed circuit board (10) having a mounting portion 13 and a motor connecting member (11); a vibration motor (1) connected to the motor connecting member (11) and capable of generating vibrations; a motor cushion (25) for elastically holding the vibration motor (1); and a rectangular frame (52) for holding the motor cushion (25), wherein a second bent portion (60) and a third bent portion (61) for preventing transmission of vibrations generated by the vibration motor (1) are provided between the mounting portion (13) of the flexible printed circuit board (10) and the motor connecting member (11) of the same.

Abstract: In DDC1, a data request signal is applied to overlap a vertical synchronization signal from a computer 1 to a terminal 33, the data request signal is applied from a receiver 24 through a switch 25 to a non-volatile memory 27, information related to a video monitor 4 is read from the non-volatile memory 27, and the read information is applied from a driver 21 through a data terminal 31 to the computer 1. In DDC2B, a data request signal is applied to both the data terminal 31 and a clock terminal 32, a part of the data request signal is decoded by a data request decoder 28 through a receiver 22, the data request signal is applied through the switch 25 to the non-volatile memory 27, information is read from the non-volatile memory 27, and the read information is applied from the driver 21 through the data terminal 31 to the computer 1.

Abstract: An immersion type automatic ultrasonic testing apparatus for detecting flaws of balls comprising a tank for containing a liquid medium of transmitting ultrasonic wave, a ball rotating device for rotating a ball to be tested, an ultrasonic flaws detection device for detecting surface flaws in the ball while swiveling a probe around the ball rotated by the ball rotating device or rotating the ball spirally by the ball rotating device with or without swiveling the probe, and a ball feeding device for feeding the ball to the position of the ball rotating device. The ball feeding device comprises an air cylinder for holding the ball by suction at the tip thereof. For the suction holding of the ball at the tip of the air cylinder, a level regulating device is additionally provided for setting a level of the liquid medium of transmitting ultrasonic wave in the tank wherein the ball rotating device and the ultrasonic flaws detection device are placed.
