Abstract:
A pyroelectric IR-sensor in which a pyroelectric light receiving element is mounted on a MID substrate or a ceramic substrate of which thermal conductivity is less than 0.02 cal/cm.sec..degree. C. in a manner that both end portions of the pyroelectric light receiving element are supported by the substrate with the central portion of the pyloelectric light receiving element being spaced from the substrate, and chip parts are further mounted on the substrate.
Abstract:
An improved chip type piezoelectric resonator in which an element having electrode layers formed on main surfaces of a piezoelectric substrate is held in a rubber-like elastic member filled in a through-bore axially formed in a chip-like case having predetermined external dimensions so as to be capable of effecting thickness shear vibration, with a consequent elimination of scattering or deviation in the external dimensions of the piezoelectric resonators.
Abstract:
A printer control apparatus including a printer search section that searches for, acquires and stores information indicative of printers connected to the network, in a printer information storage section; a network information acquiring section that acquires network information of first and second networks connected to the printer control apparatus at different times and that stores the acquired network information in a network information storage section; and a printer information acquiring section that acquires printer information from the printer search section in a case where the network information of the second network is different from the network information of the first network by causing the printer search section to conduct a search, and acquires the printer information from the printer information storage section in a case where the network information of the second network is identical to the network information of the first network.
Abstract:
An information communication system is provided, which, through the use of a standard network technology, links a server terminal to an information apparatus, and allows the use of application software and data stored on another server terminal. A web server terminal includes a main program running in response to logging in from the information apparatus, and a subprogram running in response to direct logging in from the web server terminal and requiring user authority different from that for the main program. The main program receives and delivers information using internet server software that is limited in access to another server terminal connected by network connection, and the subprogram is allowed to make access to another server terminal without using the internet server software. When the main program is incapable of obtaining information stored on another server terminal, the subprogram is entrusted with obtainment of the information.
