Abstract:
A method of controlling a base station is disclosed. Wireless signals received by the wireless terminal are checked for connection information indicating an attempt to connect to a second base station. The method determines whether the wireless terminal is located in a coverage area periphery of the base station in based on receiving the wireless signals, if the wireless signals indicate the attempt to connect to the second base station. The registration status of the wireless terminal is checked by the first base station, if the wireless terminal is located in the coverage area periphery.
Abstract:
A wireless communication apparatus (100) includes a broadcast/multicast reception determination unit (120) for determining whether data distributed by broadcast/multicast is being received or not; a wireless session close process unit (140) for performing a wireless session close process when a wireless session close timer is expired; and a control unit (150) for controlling the wireless session close process unit to hold the wireless session close process activated based on expiration of the wireless session close timer until reception of data distributed by broadcast/multicast is completed, in case that it is determined that data distributed by the broadcast/multicast is being received when the wireless session close timer is expired.

Abstract:
An analyzing apparatus has a partition dividing the interior of a housing into a lower space accommodating a power supply/control unit which generates heat and a duct and an upper space accommodating other units. Heat generated by cooling devices is exhausted to the exterior of the housing through the duct while the heat generated by the power supply/control unit is otherwise exhausted to the exterior. This construction makes it possible to achieve an improved heat exhaust efficiency and efficient cooling of a reaction unit provided in the upper space of the housing. A cover holding mechanism includes at least one each spring cam hinge and friction hinge. The spring cam hinge is formed of a cam mechanism and a spring which together produce a force acting on a cover in its opening or closing direction, the direction of the force reversing at a specific angle of the cover halfway between its open and closed positions, while the friction hinge produces a frictional force which works to hold the cover at any position between its open and closed positions. The spring produces an auxiliary force to facilitate cover-opening action, and the force produced by the spring works together with the frictional force to prevent the falling of the cover during its closing motion, enabling smooth cover-opening and closing actions.
Abstract:
A development aid device for development of a ladder program such as a user program for a programmable controller has a program memory for storing the user program and an outline data generating part for sequentially scanning constituent elements of this stored user program to extract specified elements including output commands and generating outline data by assigning individual index numbers to these extracted elements sequentially in the order of their appearance on the user program. An outline data memory stores the generated outline data. A cross-reference data generating part generates cross-reference data by extracting commands having a same operand from the user program, and a cross-reference data memory stores the generated cross-reference data. A display device is provided with a user program display area for displaying the user program, an outline data display area for displaying the generated outline data in a tree form in the order of appearance, and a cross-reference data display area for displaying the cross-reference data.
Abstract:
A method of receiving and displaying RDS data, which are multiplexed to a broadcast electric wave, includes the steps of: receiving the broadcast electric wave; detecting predetermined data in the RDS data, which are included in the received broadcast electric wave; storing at least one of the detected predetermined data into a memory device; selecting the stored predetermined data on the basis of an externally generated instruction; and displaying the selected predetermined data.
Abstract:
A semiconductor device capable of solving problems involved in a conventional semiconductor device in that when a clock frequency is multiplied in the semiconductor device itself, the generation timing the an internal reset signal is shifted owing to supply voltage fluctuation of the like, and hence a plurality of test patterns must be prepared for respective test items when testing the semiconductor device. The present semiconductor device includes an internal clock halt circuit for suspending or passing a first internal clock signal to generate a second internal clock signal to be supplied to a signal synchronizing circuit in response to a signal applied to an external input terminal, and a data latch circuit for latching an external reset signal in response to the second internal clock signal output from the internal clock halt circuit, thereby controlling the interval at which the data latch circuit stops its latch operation.
Abstract:
A communication system including a plurality of audio/video devices including one or more audio signal source devices and image (video) signal source devices connected to a bus, each audio/video device of a common type having a common bus address. Each audio/video device is provided with a predetermined priority value which is stored in memory. Upon power up, every device transmits a communication frame including its own address and its priority value on the bus. When two or more common-type devices (i.e., having a common address) are connected to the bus, conflict is avoided by disabling the device or devices having lower priority values. That is, when each of the common-type device receives a communication frame having the common address, the device compares the transmitted priority value with its stored priority value. If the stored priority value is less than the received priority value, the device disables itself. Conversely, when the stored priority value is greater than the received priority value, the device remains active (survives), and responds to further communication frames having the common address.
Abstract:
A remote-controlled apparatus improves the reliability of a vehicle security system. Each time the transmitting unit transmits data, a first code updating section changes a variable code storage in a memory in the transmitting unit by predetermined shift processing to form a new variable code, and replaces the preceding variable code with the new variable code. An ID code setting section sets an ID code formed of the variable code and a fixed code. Predetermined data including the ID code and command signals is transmitted. When the receiving unit receives the predetermined data, the fixed code and the variable code in the received ID code are compared with a fixed code and a variable code stored in the receiving unit. If it is thereby determined that the fixed codes and predetermined portions of the variable codes coincide with each other, a predetermined security operation is started or stopped according to the content (command signals) of the received data, and a code updating section in the receiving unit changes the received variable code by predetermined shift processing to form a new variable code, and replaces the preceding stored variable code in the receiving unit with the new code.
Abstract:
Near a discharge device (48) for discharging paper (P) with an image formed thereon, there is provided a punch (7) for punching holes. The drive of the discharge device (48) is controlled so that the punch punches the punch holes in the trailing portion of the paper (P), without causing creasing or tearing or change in the quality of the paper (P). The punch (7) includes punching cutters (72) and a punching die (74). The punching cutters (72) and the punching die (74) are provided in a unit (U) which can be drawn out of a casing (1) covering the punch (7). With the unit (U) drawn out of the casing (1), jam recovery can be easily executed. The unit (U) is movable in the width direction of the paper (P), thereby making it possible to adjust the position of punched holes. A collecting box (76) for collecting paper scraps (P1) is disposed in the unit (U). If the collecting box (76) is pivoted or the opening (76a) thereof is lifted up when the unit (U) is pivoted, the paper scraps (P1) therein will not fall out. Delaying timing for plural punching cutters (72) to punch holes can reduce the load on the drive system.
