摘要:
An automotive audio system separates audio signals from an audio signal source into first and second components. The first component of the audio signal is sent directly to a first main amplifier through a first audio signal path and reproduced through a main speaker or speakers. On the other hand, the second component of the audio signal is sent to a second main amplifier through a second audio signal path. An echo system is provided with the second audio signal path, which echo system induces echos in the audio sound to be reproduced through the second main amplifier. The echo system is associated with a discriminator circuit which receives an audio signal output from the audio signal source and derives an echo system control signal on the basis of the audio signal. The echo signal control signal is fed to the echo system for controlling operation of the echo system.

A system for reproducing stereophonic signals to create a stereophonic sound image in front of each of listeners sitting side by side in a compartment. The system includes a right-hand loudspeaker positioned relative to the right of the first listener sitting on the right, a left-hand loudspeaker positioned relative to the left of the second listener sitting on the left, and a center loudspeaker positioned between the right- and left-hand loudspeakers. A signal generator generates R and L stereophonic signals. The R signal is applied to drive the right- and left-hand loudspeakers. The L signal is fed to drive the center loudspeaker. The signal generator includes a circuit for attenuating the R signal to the right-hand loudspeaker and a circuit for attenuating the R signal to the left-hand loudspeaker.
摘要:
An automotive audio system separates audio signals from an audio signal source into first and second components. The first component of the audio signal is sent directly to a first main amplifier and reproduced through a main speaker or speakers. On the other hand, the second component of the audio signal is sent to a second main amplifier after a predetermined delay time determined by a delay circuit. The delayed second component of the audio signal is reproduced through a auxiliary speaker or speakers after the predetermined delay time. The first and auxiliary speakers are distinct and preferably located at different points in the vehicle compartment. As a result, the directly reproduced first component and the delayed second component are reproduced through different audio sound sources. This affords the listener higher-quality audio sound and better ambience. If necessary, an echo signal generator may be added to the second component reproduction system to provide an echo effect. In this case, since the second component is reproduced by the second speaker or speakers which are different from the main speaker or speakers which reproduce the direct first component, the echo effect can be optimized for good ambience.

To allow inspecting whether a security check of a planned outgoing email is finished in an outgoing email check system, a check data providing apparatus 2 of an outgoing email check system 100 stores check information distributed from a check information management apparatus 1, appends check data generated based on the check information to a header of a checked planned outgoing email, and transmits the email to an email transmitting apparatus 9. A check data inspecting apparatus 3 stores the check information distributed from the check information management apparatus 1, inspects the check data extracted from the planned outgoing email received from the email transmitting apparatus 9 based on the check information, determines that the transmission is permitted when the check data of the planned outgoing email matches the check information, and determines that the transmission is rejected when the check data does not match the check information. The email transmitting apparatus 9 executes a transmission process only for the planned outgoing email for which the transmission is permitted.

In a method of manufacturing a semiconductor device, element properties of an element property extraction pattern formed on a semiconductor wafer is extracted as element properties of a current control element corresponding to the element property extraction pattern. A supply energy to the current control element is set which is formed between nodes on the semiconductor wafer, based on the extracted element properties. The set supply energy is supplied to the current control element to irreversible control an electrical connection between the nodes through the device breakdown by the current control element.

An object of the present invention is to make available a pivoting display device which enables a display unit to be assuredly stowed even by using a relatively small elastic component, and which has enhanced reliability and is space-saving. When a power switch becomes off, a monitor which can be stowed is swung by urging force from a coil spring. In an initial stage in which counter-electromotive force Vm induced by a motor is greater than on-voltage of a FET, the counter-electromotive force Vm acts as rotation resistance for the motor. When the monitor approaches a stowage position, the rotating speed of the motor is reduced. Therefore, bias voltage of the FET is reduced due to reduction of the counter-electromotive force Vm, and the braking force imposed on the motor by the counter-electromotive force Vm is gradually reduced, thereby increasing pivoting speed.

An information retrieval terminal provides keywords to an information retrieval device and instructs it to retrieve by using such keywords. The information retrieval terminal includes an information collector for collecting screen information, image information, and voice information around the information retrieval terminal and for obtaining text information from the collected information. A keyword-candidate extracting unit extracts a word related to a retrieval word input by a retriever from the text information obtained by the information collector, and sets the extracted word to be a keyword candidate. A retrieval instructing unit gives an instruction to retrieve by using the retrieval word and the keyword candidate set by the keyword-candidate extracting unit as keywords.
