摘要:
An unprocessed substrate is conveyed to a film-processing chamber at the same time a processed substrate is conveyed to a substrate preparation chamber, reducing the substrate processing cycle, thereby increasing the yield per unit time. The substrate preparation chamber has a two-tiered structure for receiving processed substrates and unprocessed substrates. A two-tiered transfer robot allows the substrates to be removed or placed into the preparation and process chambers at the same time, thus decreasing the cycle time for processing a substrate.

In a circuit for driving a latching relay for use in a telephone set, a capacitor is charged from a battery, and when the capacitor is charged to a predetermined value, the capacitor is disconnected from the battery. Thereafter the latching relay is driven by the discharge current of the capacitor. With this circuit, it is possible to prevent unnecessary consumption of the battery.

Equipment for management of terminal identification numbers in a communication system, including a center and a plurality of terminals connected to the center. Identification numbers of respective terminals registered in advance are attached to data communicating between the center and the respective terminals. Each of the terminals comprises a terminal side memory means for registering the terminal identification numbers therein, initial identification numbers initially registered, means for communication with the center for effecting data communication with the center, terminal side registration means for erasing the initial identification numbers registered in the terminal side memory to register the new terminal identification numbers and the center into the terminal side memory, terminal side control means operative so that when an arbitrary one of the terminals is communicatably connected to the center, the control means delivers a predetermined registration request data to the means for communication with the center to allow the communication means to transmit it to the center.

The display device for a telephone set is designed to be capable of storing in advance the telephone number, person's name, company name, etc. of any desired (one or more) party (subscriber) through the numeric data input means and character data input means which typically use the dial keys of the telephone set, and proper software keys, recognizing the special dial operation made by the user via the specific software keys for telephoning, checking the memory whether the data corresponding to the dialed number is stored, reading the data from the memory if stored, and displaying in the display unit preferably giving the priority to the character data showing the name, company name, etc.
摘要:
A telephone set which has a hands-free mode of operation is disclosed. The telephone set includes a telephone circuit connector to a handset and a hands-free circuit connected to a loudspeaker. A hook switch is mechanically operated in accordance with operation of the handset. A semiconductor switch is connected in parallel with the hook switch and is controlled by a control circuit. The telephone circuit or hands-free circuit is selectively connected to a pair of telephone lines through the hook switch or the semiconductor switch.

An output voltage of a first diode deriving out an office line voltage, and an output voltage of a second diode deriving out the voltage of a back-up battery are combined and then smoothed by a smoothing capacitor. The smoothed voltage is supplied to a control circuit. A voltage limiting circuit is connected to the input side of the first limiter for limiting the upper limit of the smoothed voltage. A switch circuit is provided which is rendered conductive at the time of talking and the at the time of sending out a dial pulse for combining the office line voltage with the combined voltage. A voltage limiting circuit is also provided which is enabled only at the time of talking and at the time of sending out a dial pulse for limiting the upper limit of the combined voltage.
摘要:
A telephone apparatus having the standard ten digit keys and two special keys, and in the handset the conventional switchhook. By manual operation of the two special keys and the switchhook the apparatus can be operated in any one of a plurality of modes, at least some causing transmission of stored sequences of digits in response to entry of an abbreviated address or in causing redialing. In one mode data signals are produced and transmitted in response to not only the digit keys but also the special keys as well. A controller operates the apparatus and is connected to a dial sender which converts the data signals into a multi-frequency signal which is transmitted by a telephone network to a repeater station.
摘要:
A telephone apparatus which can input character/symbol data. The apparatus has a keyboard including a plurality of numeral keys each assigned to characters/symbols, a mode change key for switching numerical mode to character/symbol mode, or vice versa and a special key for executing a predetermined sequence. After the apparatus has been set to the character/symbol mode, the numeral keys assigned for the characters/symbols and the special key are operated in the predetermined sequence, thereby inputting character/symbol data. The data are applied to a electronic calculator CPU, are outputted in the form of character/symbol pattern signals from a character generator, and are displayed by a display section in the predetermined sequence.
