An apparatus and a method that include a program execution monitoring dedicated circuit connected to a CPU of a control apparatus of an on-vehicle electronic equipment that includes an execution time monitoring timer circuit, an execution sequence monitoring comparison circuit, a setting register, an other attached circuit and so on, perform monitoring of an execution sequence of a task executed by a control program of the on-vehicle electronic equipment and/or an execution time from a head address to an end address of the task executed by the control program, and enable the control of the on-vehicle electronic equipment such as an electric power steering apparatus to be continued by performing an alternative processing in the case of detecting an abnormality in the execution sequence and/or the execution time.

Control apparatus and control method of on-vehicle electronic equipment

A control apparatus of an on-vehicle electronic equipment. The control apparatus of the on-vehicle electronic equipment monitors an execution time of each normal processing obtained by subdividing a control program of the on-vehicle electronic equipment by means of an MCU which is provided in the control apparatus. In a case that an abnormality in the execution time of the normal processing is detected by a timer interruption processing based on a general-purpose timer built in the MCU and software, an alternative processing to be paired with the normal processing is performed to continue a control of the on-vehicle electronic equipment by replacing the normal processing with the alternative processing in a next period.

A multi-layer laminated circuit boardA of the present invention is formed by laminating together a multi-layer transformer, a multi-layer part sheetformed with a multi-layer part, and a wiring sheetformed with a circuit pattern. The multi-layer transformeris incorporated into the multi-layer laminated circuit boardA, and therefore a package for the multi-layer transformeris omitted, and the wiring between the multi-layer transformerand other components is reduced to a minimum.

Multilayer laminated circuit board

Solid electrolytic capacitor and manufacturing method thereof

A communication terminal apparatus and a communication intercepting apparatus performs a communication interception even on a communication network such as the Internet, an Intranet, or the like in which a communication route is not fixed. While the communication terminal apparatus is executing voice communication with another communication terminal apparatus, the communication intercepting apparatus transmits a monitor request signal to the communication terminal apparatus. When the monitor request signal is received, the communication terminal apparatus stores voice data which is transmitted to another communication terminal apparatus and voice data received from another communication terminal apparatus into a monitoring packet and transmits the monitoring packet to the communication intercepting apparatus. The communication intercepting apparatus receives the monitoring packet and reproduces the transmitted packets.

Apparatus for intercepting communication data in a packet network

A message providing apparatus according to one embodiment is apparently a small-sized (for sample, screen size of about 3.5 inches) flat display (for example, LCD), wherein a speaker is provided at a cabinet, and a memory card that is a message data storage medium is inserted into the cabinet. Advertisement display data is stored to be classified into a moving image layer indicating a landscape, a still image layer indicating a commodity, a graphic (POP) layer indicating a price, a character layer indicating a catch phrase, and a sound layer which are displayed to be superimposed as required. BGM music data is also stored as the sound layer, and is reproduced in synchronism with a display. Advertisement characters are printed at the cabinet. When power is supplied, the apparatus automatically starts data reproduction of the memory card (by using a power on play function), and when all the data has been reproduced, the apparatus automatically restarts reproduction (by using an auto replay function). The message providing apparatus can be disposed on a commodity display shelf in place of a conventional advertisement providing apparatus so that image or sound information such as television commercial message popular among consumers can be distributed near commodities.

Message providing apparatus

Disclosed is a semiconductor plastic package having a structure in which a metal sheet having a size nearly equivalent to a printed wiring board is disposed nearly in the central portion in the thickness direction of the printed wiring board. The metal sheet and a signal propagation conductive circuit on a front surface of the printed wiring board are insulated from each other with a thermosetting resin composition. The conductive circuit on the printed wiring board surface is connected to a conductive circuit formed on an opposite surface of the printed wiring board, or to a conductive circuit pad formed for being connected with solder balls with a conductive through hole. A semiconductor chip, wire and bonding pad are encapsulated with a resin. The semiconductor plastic package has at least one blind via hole made in the opposite surface so as to be directly connected to the metal sheet. The blind via hole has an inner wall rendered thermally conductive. The printed wiring board is provided, on the semiconductor-chip-mounting side, with an elevated metal portion, a plurality of metal protrusions each having the form of a frustum of a pyramid or a cone, or at least one via hole having an inner wall rendered thermally conductive. A process for the production of a printed wiring board used for the above plastic package is also disclosed.
