Abstract: A method of reducing a noise generated from a speaker at the time of power on/off in an audio output device that drives the speaker. The device includes a digital DC attenuator, a D/A converter, and an operational amplifier. The attenuator gradually changes an output digital value from a first digital value to a second digital value. The converter converts an output from the attenuator into an analog signal. The amplifier amplifies an output from the converter and drives a speaker. At the time of power on, the output from the attenuator is gradually changed from a digital value corresponding to the ground level to a digital value corresponding to the signal ground value. At the time of power off or system reset, the output from the attenuator is gradually changed from the digital value corresponding to the signal ground value to the digital value corresponding to the ground level.

Abstract: A display data packet contains identification information. A display unit communication system includes a control unit, a terminal adaptor to which a terminal adaptor ID is assigned and which is connected to the control unit, and a display unit to which a display unit ID is assigned and which is connected to the terminal adaptor in series and drives a display element according to the display data packet supplied from the control unit. The terminal adaptor receives a display data packet, the terminal adaptor ID of which agrees with that contained in the identification information, and transfers the display data packet to the display unit. The display unit receives the display data packet, the display unit ID of which agrees with that contained in the identification information, and drives the display element to display an image.

Abstract: The present invention provides a bump forming apparatus which can prevent charge appearance semiconductor substrates from pyroelectric breakdown and physical failures, a method carried out by the bump forming apparatus for removing charge of charge appearance semiconductor substrates, a charge removing unit for charge appearance semiconductor substrates, and a charge appearance semiconductor substrate. At least when the wafer is cooled after the bump bonding is connected on the wafer, electric charge accumulated on the wafer because of the cooling is removed through direct contact with a post-forming bumps heating device, or the charge is removed by a decrease in temperature control so that charge can be removed in a noncontact state. Therefore, an amount of charge of the wafer can be reduced in comparison with the conventional art, so that the wafer is prevented from pyroelectric breakdown and damage such as a break or the like to the wafer itself.

Abstract: Each horizontal driving section and a driving control section of a display apparatus have a data communicating function. The driving control section has a first communicating section receiving data from an external device and a second communicating section communicating data with each horizontal driving section. The second communicating section adds individual identification information for identifying each horizontal driving section to the transferred data, and transfers the data in packet format. The horizontal driving section receives the data packet for it based on the identification information, and performs current driving for a display section. The driving control section adds the individual identification information to the control data to be transferred to each horizontal driving section corresponding to connecting form of the horizontal driving sections, and transfers the control data not concerned with connecting order of the horizontal driving sections.

Abstract: In synchronous communication in a client-server-distributed data system, the turnaround time from when a client calls a server function until the client receives a notification of completion of the server function is reduced. A server includes a pre-processing registration section for registering pre-processing; a post-processing registration section for registering post-processing; a server command section for requesting to register the pre-processing and the post-processing; and a server function correspondence section for establishing correspondence between the pre-processing and the post-processing with a server function identifier. When the server receives a request message from a client to call a server function, the server execute pre-processing and sends a completion message including the execution result of the pre-processing to the client. After sending the completion message, the server executes post-processing.

Abstract: A shut-off device (1) for protection against explosions in a pipe-line is fitted with a slide valve plate (10) movable transversely to the direction of flow (A). The slide valve plate is connected via a piston rod (25, 26) to a piston (27, 28) slidably guided in a cylinder (35, 36) and actuated by a pressure medium. The pressure medium is supplied from a pressure medium reservoir via a closing valve (45) to a working chamber (46, 47) of the cylinder (35, 36), thereby actuating the piston and causing the slide valve plate (10) to move into a position closing the pipe passage (4). At least one cylinder (35, 36) is arranged within a pressure chamber (40) enclosed by a housing (30), which forms the pressure medium reservoir. Thus, a compact, space-saving shut-off device is created which can be shut within a very short time.
