Abstract: A loudspeaker unit includes a voice coil, a diaphragm, a damper, a frame supporting an outer edge of the diaphragm and an outer edge of the damper, and a duct projecting from an outer surface of the frame, with air moved by vibration of the diaphragm flowing into and out of the loudspeaker unit through the duct. The frame has an aperture that communicates with a space inside the frame. The duct, serving as a separate member, is attached to the frame so as to cover the aperture. The frame further includes a support tab that projects into the aperture. Link terminals are attached to the support tab. Before the duct is attached to the frame, lead wires extending from the voice coil are formed into a predetermined shape and are then connected to the link terminals in a space within the aperture.

Abstract: An opening is formed in a ceiling lining of a vehicle cabin part. The diameter of the opening in the ceiling lining is smaller than a diameter of a speaker, which has a frame. The speaker is disposed at the opening, and a fixing screw is inserted into a fixing aperture formed in a central part of the speaker. A fixing screw is screwed to a screw hole formed in a reinforcing brace positioned at an inner side of a top plate proximate the ceiling of the vehicle. A central part of the speaker is fixed to the reinforcing brace while a circumferential periphery of the frame is pressed against a peripheral edge of the opening in the ceiling lining via a frame interposing material.

Abstract: A speaker device includes a cabinet from which a duct for adjusting the back pressure protrudes, a speaker unit mounted in the cabinet, and an intermediate hollow member including first and second connection portions. A cabin space in which the cabinet is installed is separated from a non-cabin space by a partition wall. If there is a subframe facing the partition wall, the duct cannot be directly connected to the opening formed in the partition wall. The intermediate hollow member is disposed in a small space between the subframe and the partition wall, the second connection portion is connected to the opening, and the duct is connected to the first connection portion.

Abstract: Each of a plurality of option devices includes a signal changing unit connected to a first control unit of a recording apparatus without a second control unit of another option device and configured to change a signal supplied from the first control unit, and a communication line configured to connect the first control unit and the second control unit without the second control unit of another option device. The first control unit determines the number of the option devices by inputting a signal to the signal changing unit in each of the plurality of option devices. After that, in the case where communication can be performed between the first and second control units, it is determined that the second control unit of the option device is normal. In the case where the communication cannot be performed, it is determined that the second control unit is faulty.

Abstract: A speaker includes a magnetic circuit, a voice coil, and a diaphragm which are disposed in a case. The case is placed in an engine compartment of an automobile. Reproduced sound is emitted through a duct protruding outward from the case. A partition wall, which is a metal body frame of the automobile, is present between the engine compartment and the cabin space. The duct is inserted into a hole formed in the partition wall so that a sound port faces and protrudes into the cabin space. A heat dissipation port is formed in the case, and an end surface the magnetic circuit facing the partition wall is exposed in the heat dissipation port. An elastically deformable thermal conductive sheet is sandwiched between the partition wall and the end surface of the magnetic circuit.

Abstract: An electronic control unit is incorporated as one of a plurality of electronic controllers composing a system for controlling in-vehicle devices on a distributed and mutually-synchronized control manner in a vehicle. The plurality of electronic control units are communicably connected with each other via an in-vehicle network to communicate information including the time-dependent data among the electronic control units. Each electronic control unit comprises a control member, an elapsed-time calculation component, and a validity determination component. The control member performs the control on the basis of time-dependent data acquired in time series relating to the vehicle. The elapsed-time calculation component is configured to calculate an elapsed time elapsing from acquisition of the time-dependent data.

Abstract: A method and device for managing a task upraised according to receiving a processing request of services in in-vehicle electronic control units are provided. The method and device include the steps of: allocating a plurality of services to one task and determining whether or not the task assigned with the service is in process of execution in receiving the processing request of the service; and upraising the task to process the service of the received processing request when determination is made that the task is not in process of execution in the determining step, and making the task in process of execution continuously process the service of the received processing request without newly upraising the task when determination is made that the task is in process of execution in the determining step.

Abstract: A vehicle control system is configured by basic control units of a power train control unit, a steering control unit and a brake control unit that are arranged in a lower control hierarchy level, a vehicle motion control manager unit that is arranged in a middle control hierarchy level, and a driving support control unit that is arranged in an upper control hierarchy level. The basic control units transmits input data to vehicle motion control manager unit of middle control hierarchy level and/or driving support control unit of upper control hierarchy level, and receives a calculation result of the input data substituted into a predetermined calculation formula at vehicle motion control manager unit and/or driving support control unit. If the input data and the calculation result data are not consistent, it determines that there is a failure in vehicle motion control manager unit and/or driving support control unit.

Abstract: A data storage device executes a program including the steps of: determining whether or not a storage instruction to include data to be stored, along with a class generated as a label common among application software, has been obtained; detecting a class in the contents of the storage instruction when the storage instruction is obtained; determining a storage manner based on the class and a table defining in advance storage manners; and storing data in an appropriate storage medium with appropriate data redundancy based on the determined storage manner.

Abstract: A flexible wiring board are formed by growing metal bumps using a mask film patterned by photolithography. Fine openings can be formed with good precision, therefore, fine metal bumps can be formed with good precision because laser beam is not used to form opening in a polyimide film. After metal bumps have been formed, the mask film is removed and a liquid resin material is applied and dried to form a coating, which is then cured into a resin film. The coating can be etched at surface portions during coating stage to exposed the tops of metal bumps.
