Abstract: A small-sized alarm device is hung on a doorknob to emit an alarm sound upon detecting that a human body contacts or approaches the doorknob. The alarm device has data processor, such as a calculator and the like, in addition to an alarm and an electro-optic display for displaying data processed by the data processor and information related to the operation of the alarm. To the alarm device is rotatably mounted a hanging member for hanging the alarm device on a doorknob. The hanging member is fit into the case of the alarm device when in not use or is erected from the case when the alarm device is hung on the doorknob.

Abstract: An image processing apparatus includes an imaging lens, an area image sensor having solid-state imaging elements arranged in a planar manner, and an imaging device for converting an image of an imaging object read by the area image sensor into image information. The imaging device is switchable between an electronic camera function mode and image scanner function mode. When the device is switched into the electronic camera function mode, the image information for one frame is outputted, whereas when the imaging device is switched into the image scanner function mode, the image information derived when an object to be read is manually scanned by the area image sensor in response to a moving amount of the manual scanning operation is outputted as continuous image information. Image information may thus be acquired over a wide range by employing a single image information processing apparatus.

Abstract: When one message data is transmitted dividedly at plural times to the same reception terminal, in the first transmission, a code specifying the terminal is transmitted, and then message data in a head portion of the message and a code indicating that succeeding data is present are transmitted, in the second transmission and thereafter, the code specifying the terminal is transmitted, and then data succeeding to the transmitted message data and a code indicating that the previously transmitted message data is continued from message data received at this time, and, unless the second transmission and thereafter is the last transmission, the message data having a code indicating that succeeding data is present are transmitted. The reception terminal receives transmitted data, and connects message data transmitted dividedly at plural times as one message data based on the code attached to the received message data.

Abstract: A CPU enables an FM tuner, a tuning controller and an FM multiplex decoder, after which the CPU is disabled. The FM tuner, tuning controller and FM multiplex decoder receives frame data including emergency information transmitted from a broadcasting station. When a packet coincidence circuit determines that the received block is a specific block which may include emergency information, the FM multiplex decoder causes an emergency information determining circuit to determine if the associated packet contains emergency information. If this packet contains emergency information, the emergency information determining circuit sends an interrupt signal to the CPU to enable the CPU. The CPU then reproduces the emergency information in the received data and displays it on a display section.

Abstract: To provide a machine composer capable of efficiently composing natural melodies with a simplified system configuration and without requiring complicated data processing: A melody material storage 10 stores a plurality of melody materials each represented by a plurality of note records. Each note record in a melody material contains data items of pitch and note type or function. Thus, pitches of the plurality of note records constitute an original pitch succession whereas note types of the records define an original note type succession. A note type of each note record represents a pitch function specified by musical background of the original pitch succession. A input device 20 enters musical background information (including for example keynote, scale and chord).

Abstract: A semiconductor device has a connection electrode and protective film formed of organic material and covering the connection electrode. An opening is formed in the protective film to expose the connection electrode. A natural oxide layer is etched by argon-based dry etching. The surface layer of the protective film is altered to reduce the insulativity in the dry etching process. After a projection electrode is formed on the connection electrode later, the altered surface layer of the protective film is removed by oxygen-based dry etching. As no altered surface layer remain on the protective film, an adverse affect such as inadequate insulation does not occur.

Abstract: A display data memory which is provided in a segment driver for driving a liquid crystal display panel comprises a plurality of memories. Since the common Y address is provided to all the memories, one predetermined memory is selected when a predetermined X address is decoded. At the time of writing data, a predetermined area in one memory is addressed according to X and Y addresses, and then data is written in the predetermined area. In case data is read out to be displayed, the memories are prohibited from being selected according to outputs from decoders. Data addressed by the common Y address are read out from the memories. Therefore, display data of one line are output as segment signals at a time.

Abstract: Whether or not the reception condition of a received broadcast is good is detected by a reception condition detection unit. If it is detected that the reception condition is good, the broadcast content in the good reception condition is displayed on a display unit. However, if it is detected that the reception condition is not good, another broadcast content in a good reception condition is automatically received, and the broadcast content in the good reception condition is displayed on the display unit. The reception condition is evaluated in a plurality of stages depending on the reception condition of the received broadcast, and the evaluation result is displayed. If it is detected that the reception condition is not good, power supply to an apparatus main body is stopped after an elapse of a predetermined period of time. After an elapse of another predetermined period of time, the reception condition detection unit detects again whether or not a good reception condition is attained.

Abstract: A service center has a plurality of controlled areas. When the service center provides service information through a radio communication network, the service center first broadcasts toward all the areas with outline items of the information with corresponding key codes attached thereto. Users each receive the outline items of the information with a user's terminal and determine as required whether a detail item of the information should be had immediately (an urgent one) or can be had later (a regular one). The results of the determination are reported to the service center, which immediately provides the urgent detail items of the information for the respective users who made requests for having those detail items. The service center broadcasts regular detail items of the information with attached corresponding key codes other than the requested urgent ones of the information toward the terminals which requested the regular detail items of the information at a predetermined time.
