摘要:
A video server in which each media segment file sever (MSFS) stores media segment files (MSFs) forming video data, and sequence control brokers (SCBs) installed between the video server and subscribers terminals receive video requests from the subscriber terminals, and read out the requested MSFs from the MSFSs. The readout MSFs are exchanged by an ATM switch to be transmitted to the SCBs respectively, which outputs the MSFs at predetermined intervals to the request-sender subscriber terminals.

A charge coupling for an electric vehicle wherein conduction is enabled from a charger to an electric vehicle battery when a supply connector to the charger is completely fitted to a vehicle inlet installed in the electric vehicle. A locking member is provided for temporarily locking the supply connector to the vehicle inlet at a half fitting position, the locking device being further provided with a spiral groove extending from the half fitting position to the complete fitting position. An engagable boss which projects from a distal end of either the vehicle inlet or supply connector is adapted to detachably engage the spiral groove and the supply connector is provided, on its outer periphery, with a handle for assisting rotation of the supply connector so that the engagable boss moves within the spiral groove from an outer end to a terminating end. A holding member is provided on either the vehicle inlet or supply connector and serves to maintain the supply connector at the complete fitting position in the vehicle inlet when the engagable boss reaches the terminating end of the spiral groove.

To form a contact layer on source and drain electrodes of a stagger-type TFT, a conductive material is selectively sticked to the surface of the source and drain electrodes and a contact layer is selectively deposited by using the conductive material as growth species to form an active semiconductor layer on the contact layer. For an inverted-stagger-type TFT, a conductive material is selectively deposited on the surface of a contact layer to use the selectively deposited conductive material as source and drain electrodes so that patterning is unnecessary. To selectively deposit a contact layer of a TFT by alternately repeating etching and deposition, the temperature for the etching is set to 200.degree. C. or lower. A contaminated layer on the surface of a semiconductor film serving as an active semiconductor layer and contact layer of a TFT is removed by plasma at the temperature of 200.degree. C. or lower. For a stagger-type thin-film transistor, the hydrogen or halogen content of an insulating film serving as the substrate of source and drain electrodes is increased. For an inverted-stagger thin-film transistor, the hydrogen or halogen content of an insulating film serving as a channel protective film is increased. Thus, the etching rate of the surfaces of these insulating films by plasma increases.

A coupling device interconnects a car connector BC and a charger connector SC positively by a small force to charge a battery in an electric car. After incompletely coupling, when an operation lever 8 together with a grip 32 are grasped, a sector gear 16 is turned to an anticlockwise direction and a pinion 15 is rotated to the anticlockwise direction through an intermediate gear 17. Thus a coupling plate 10 is moved from an advanced position to a retracted position through engagement of the pinion 15 and a rack 13. Distal ends of the coupling plates 10 are closed during a former movement of the plates so that windows 21 in the plates receive projections 22 on a connector housing of a car connector BC. A connector housing 2 of a charger connector SC together with a body 3 are drawn into the housing 1 during a latter movement of the plates, thereby completely interconnect both connectors BC and SC. When the lever 8 returns to an opening position, the coupling plate 10 is backed from the retracted position to return the housing 2 together with the body 3 and detach the housing 1. When the body 3 is pulled, both connectors BC and SC are separated.

A resistor-provided UHV breaker has a tank sealing an insulating gas therein, a main contact unit located in the tank, a resistor unit connected parallel to the main contact unit, a resistor contact unit located in the tank, a main contact making/breaking unit for making and breaking the main contact unit, and a resistor contact making/breaking unit for making and breaking the resistor contact unit. Further, the breaker has a coupling unit for coupling the main contact making/breaking unit with the resistor contact making/breaking unit. The coupling unit drives the main contact making/breaking unit together with the resistor contact making/breaking unit during closing operation of the main contact unit, and drives the main contact making/breaking unit and the resistor contact making/breaking unit, independently, during breaking operation of the main contact unit.

A low-temperature showcase comprises a heat insulated wall, on the top of which an opening for putting-into or taking-out commodities is formed. The inside of the heat insulated wall is divided into an air passage and a storage chamber thereover by a dividing plate which is installed inside this heat insulated wall in a nearly horizontal fashion. The air passage is formed in a manner that the cross-section thereof is of a U-shape, and the storage chamber is formed surrounded by this air passage. At both ends of the air passage, vent ports are formed at the positions facing each other through the opening of the heat insulated wall inbetween. The air passage is divided into two parts by a fan case corresponding to the respective vent ports and a blast fan which can rotate reversibly is supported by this fan case. In each halved air passage, an evaporator is installed in the vicinity of the vent port, and when one of the evaporators is put in cooling operation, the other evaporator is subjected to defrosting. An electric heater is installed between each vent port and each evaporator, and these electric heaters are energized when the corresponding evaporator is to be defrosted. By means of a thermo-switch, energizing of the electric heater is stopped when the air temperature in the air passage rises above a predetermined valve during energizing the electric heater.

摘要:
A buffer storage control system is provided having a central processing unit having a buffer storage for storing a part of the content of a main storage, wherein, when a block transfer from the main storage to the buffer storage is carried out, data to be processed is transferred directly to an arithmetic unit or an instruction processing unit via a by-pass operation. The transferred data is then written into the buffer storage and only the portion written in a block can be read, even if not all of the data of one block is written into the buffer storage. During the period from the end of the by-pass operation to the end of the write operation into the buffer storage, with respect to data related to the by-pass operation and data transferred from the main storage, subsequent to the data related to the by-pass operation, the access to the buffer storage based upon a subsequent request for access is inhibited.
摘要:
In an IC card information reading and writing apparatus, a clock oscillator (4.9 MHz) is incorporated in the apparatus. Since the high-frequency clock is not passed through a cable connected between the apparatus and an external control unit, but supplied from the clock oscillator to the IC card via a short distance, the external control unit can stably control the IC card through the long cable without generating crosstalk or reflection. The clock signal is selectively supplied to the IC card via an AND gate in response to a clock-enable signal from the external control unit or a binary logic signal supply voltage for the reading and writing apparatus.
