Title: Cd-rom retrieving program using system
Inventor: OBA OSAMU
IPC: G06F17/30
Filed: 1990-03-02
Abstract: PURPOSE:To realize the effective user of the large quantity of the data of a CD-ROM without being conscious of the accessing system and the data base structure of the CD-ROM by making a function to retrieve the CD-ROM into a module. CONSTITUTION:A CD-ROM retrieving function 1 is provided with a retrieving request receiving function 2, a retrieving function 2, an accessing function 4, and a retrieved result answering function 5. The retrieving request receiving function 2 receives a retrieving request from an existing work AP 7, and makes CD-ROM retrieval 1 possible, and the retrieving function 3 makes the retrieval of data in the CD-ROM constituted based on the logical data base of the CD- ROM possible. The existing work AP 7 can use retrieved result data immediately by only issuing the retrieving request by using the CD-ROM retrieving function 1. Thus, the effective use of the large quantity of the data on the CD-ROM can be facilitated without being conscious that a user himself accesses and retrieves the CD-ROM.

IPC: B65H3/44
Filed: 1986-03-07
Abstract: PURPOSE:To easily discriminate plural kinds of copying sheets by conveying sorted originals to an image input part in order and interposing section paper among the copying sheets stored in a storage part with a signal indicating the end of copying operation. CONSTITUTION:Originals P and Q are inserted to a paper feed slit 217 and their front ends are stopped by stoppers 225 and 239 and pressed by pressing members 237 and 241. When a sensor S5 detects the original P at the start of copying operation, the stopper 225 moves down, the original is sent out from the lowest paper, sheets after the copying operation are discharged onto a storage part. Sheets of different sizes are not copied and stacked thereupon with a signal indicating the copying end of the original P. Then, the stopper 239 moves up, the original Q is copied similarly, and copied sheets are stored on said sheet. Thus, even when copy sheets are of the same size, the section paper is interposed to easily discriminate plural kinds of sheets.

Title: Fluxmeter
Inventor: NAITOU SEIICHI
IPC: G01R33/035
Filed: 1980-04-18
Abstract: PURPOSE:To enable magnetic fluxes, whose variation factor is large, to be measured, by feeding back the division output to the resonant circuit. Said output is obtained by division of a reference signal component of a double frequency and a reference signal component detected from a resonant circuit which is coupled to a squid. CONSTITUTION:When the external magnetic fluxes phiX are fed to a squid ring SQ which is maintained at a superconductive state, the inductance is varied. The variation is detected by flowing the current from an oscillator OSC to an RF resonant circuit LC of a squid probe SP. A reference signal for lock in operation is applied to the RF resonant circuit LC from the oscillator ROSC. The outputs of multipliers MA1 and MA2, wherein the output reference signal of the resonant circuit and the reference signal of the double frequency are multiplied, are divided in a divider DC. An output signal E0 is obtained from the divider DC via an integrator INT, and fed back to the resonant circuit LC. In this constitution, when the external magnetic fluxes whose variation factor is large enter the circuit and the locking cannot be made, the double frequency component is decreased, the loop gain is increased, and the locking operation is achieved.
