A network scanner apparatus is connected to a least one terminal via a network. A control portion controls the network by the use of a TCP/IP protocol. A readout portion reads-out a paper to produce an image data signal. An operation portion inputs an IP address as a transmitting destination of the image data signal. A transmission portion directly transmits the image data signal to the terminal having the inputted IP address.

System for directly transmitting an image data signal from a scanner device to a computer terminal via a network without using a server

The invention provides an image transfer system and method by which image data stored in accordance with a coding method in a facsimile apparatus connected to a network, can be outputted to a terminal equipment connected to the network. A WWW browser is initiated in the terminal equipment and sends an acquisition request for HTML document to the facsimile apparatus. In the facsimile apparatus, the acquisition notification is detected by a request analysis section through a HTTP request reception section, and a HTML document is transmitted from a HTML signaling section to the terminal equipment. The terminal equipment finds, when the HTML document which includes an acquisition request for a coding program is displayed, the request and issues an acquisition rest for a decoding program. The request analysis section of the facsimile apparatus detects the request, and a program signaling section transmits the decoding program to the terminal equipment. The decoding program includes a description for request for image data and issues, when executed, an acquisition request for image data. The request is detected by the request analysis section, and an image data signaling section acquires image data stored in an image storage section and transmits the image data. The image data is received and decoded by the terminal equipment so that it is converted into data of a format for display, and the data is displayed on a display unit.

Disclosed is a terminating circuit in a battery feed circuit of an electronic exchange system. The battery feed circuit comprises two transconductance amplifiers connected by a coupling capacitor, for supplying a direct current through a ring terminal and a tip terminal to a load. Each of the transconductance amplifiers comprises an operational amplifier; a resistor connected between the output end of the operational amplifier and the tip terminal or the ring terminal, and an impedance unit connected between the inverting input terminal of the operational amplifier and the output end. The impedance unit has an impedance determined in such a way that the required terminating impedance of the battery feed circuit when viewed from the tip terminal and the ring terminal is formed only by the internal elements including the impedance means and the resistor, whereby an external larger-size capacitance capacitor for matching becomes unnecessary.

Battery feed circuit for a pair of subscriber lines includes a voltage drive circuit with an operational amplifier having a predetermined output impedance determined by an alternating current terminal impedance for the pair of subscriber lines. Both voice signals and induced noise signals are terminated by the voltage drive circuit. The voltage drive circuit is connected in parallel with an electronic inductance circuit, between one of the subscriber lines and ground or a direct current voltage supply.

An electronic scanning antenna which effects radiation beam scanning based on a phase electronic scanning. The antenna has a plurality of radiation aperture units and power is fed concurrently to the plurality of radiation aperture units within a range of a small elevation angle. Thus, the degradation of a beam is reduced and a narrow beam can be formed with a high efficiency. Further, the antenna is configured wherein an electric field distribution on a radiation aperture plane formed by at least one radiation aperture is set so as to correspond to an electric distribution based on a predetermined design, thereby always normally maintaining aperture efficiency and radiation characteristic of a radiation beam over a range of a predetermined scanning angle.

There are provides N independent radiation opening unit adapted to form N radiation beams in a first radiation plane (N&gt;1) and a plurality of beam control means having a power variable distribution performance and a phase control performance. The control means performs radiation beam controls including switching of the radiation beam, setting of radiation power ratio for the respective radiation beams to any desired values in the first radiation plane regarding the N radiation beams, and radiation beam scanning in a second radiation plane orthogonal to the first radiation plane in a predetermined reference direction with reference to the first radiation plane. This antenna can reduce the number of the phase shifters and eliminate a high power phase shifter.
