Abstract: A detachment tool of the present invention is a tool for detaching a device attached to a wall portion. The detachment tool includes a member in which a first through hole and a second through hole are formed, a first screw that fixes the member to the device while inserted into the first through hole, and a second screw that pushes the wall portion while inserted into the second through hole. The first through hole is a threaded hole that screw-engages with the first screw or an unthreaded hole. The second through hole is a threaded hole that screw-engages with the second screw. According to such a configuration, the detachment tool in which operationality in detachment is good, flexible adaptation to a space can be made, and force applied in detachment is also easily managed, and a motor drive device provided with the same can be provided.

Abstract: A display screen changeover apparatus changes a screen display when displaying HTML contents on a display screen of a television receiver. A contents analysis part analyzes display setting information with respect to the television receiver based on address information given to the HTML contents. A display setting part sets a display of the HTML contents with respect to the display screen based on a result of analysis obtained by the contents analysis part.

Abstract: A communication device setting apparatus is arranged to register setup information in a communication device connected to the communication device setting apparatus via a communication network. In the communication device setting apparatus, a device setting unit recognizes an access from the communication device upon power up of the communication device, acquires setup information, which is specific to the communication device and contains a MAC address of the communication device, from list information pre-recorded in the communication device setting apparatus, and performs a setting process to set the acquired setup information in the communication device. A setting management unit detects an end of the setting process performed by the device setting unit, changes the list information based on the setup information having been set in the communication device after the end of the setting process, and manages the communication device according to the changed list information.

Abstract: A man machine controller (MMC) unit is connected to a computer numerical control apparatus and controls a servoamplifier or a machine such as a machine tool, a robot, or a plastic mold injection machine. The MMC permits easy upgrading, changing, and the like of display functions. The MMC includes a control circuit board for controlling the MMC unit in accordance with a command supplied from the computer numerical control apparatus. The control circuit board is equipped with a socket to which a personal computer function card is detachably connected. The personal computer function card has a processor which controls images to be displayed on a display such as an LCD. The MMC also inputs data for processing by a main processor. The main processor controls the servoamplifier or the machine in response to the input data.

Abstract: A universal joint is composed of first and second yokes each having two through holes, a hollow rectangular parallelepiped support member positioned to cooperate with the first and second yokes, the support member having five rectangular plate sections leaving a rectangular opening, and formed with four through holes, the adjacent rectangular plate sections being completely integral with each other at connecting edges thereof, and pins insertable into the through holes of the yokes and of the support member so as to connect the yokes with the support member, thereby producing a universal joint light in weight and high in torsional strength.

Abstract: A method and system for transmitting N-bit serial data (where N is a positive number) in the form of a bit serial, including a data sending circuit, a data receiving circuit and data transmission lines. The system includes a first data transmission line; a second transmission line; a transfer circuit, provided in the receiving means, for sending back to the data sending circuit through the second data transmission line, the bit content of received N-bit data each time one bit of the N-bit data is received through the first data transmission line; a comparison circuit, provided in the data sending circuit, for comparing the transmitted bit content and the bit content sent back on the second data transmission line; and a detection circuit provided in the data receiving circuit. The data sending circuit is adapted to transmit as a start bit a signal of a prescribed logical value before the N-bit serial data is sent, and, as an alarm bit, the results of the comparison after the N-bit serial data has been sent.
