Title: Afc circuit
Inventor: TSUJI AKIRA
IPC: H03J7/02
Filed: 1986-07-17
Abstract: PURPOSE:To expand the pull-in characteristic of a modulation frequency by providing a sweep control means so as to discriminate whether the modulation frequency recovered based on a control signal is within the pass band of a narrow band filter or at the outside of the band, and applying sweep control to the oscillated frequency of a voltage controlled oscillator when the modulation frequency is at the outside of band. CONSTITUTION:A sweep control circuit 6 discriminates whether a recovered modulation frequency is within the band of a narrow filter or at the outside of band by supervising an error voltage (e) and controls a sweep circuit 7 when the frequency is at the outside of band. For example, the sweep control circuit 6 converts an output voltage (e) of a phase comparator circuit 5 into a digital signal by an A/D converter, the value is fetched by a microcomputer to apply the control of sweep direction, sweep speed, control voltage of the oscillation circuit 1 and a selection circuit 8. The sweep circuit 7 is controlled by the sweep control circuit 6 to generate a control signal (g) sweeping the frequency in increasing or decreasing direction to the oscillation circuit 1. Then the modulation wave enable pull-range is expanded remarkably more than a conventional range and the allowance of a reception signal against the frequency fluctuation is relaxed considerably.

Abstract: PROBLEM TO BE SOLVED: To quickly dissolve and remove up to a low concentration the substances contained in glass fiber filter elements or attached thereto, and also to separate both the glass fiber dispersed in the dissolved solution and the solution, so that the treated glass fibers can be easily taken out. SOLUTION: In the method in which soluble sustances are dissolved by making them act on nitric acid aqueous solution including a bivalent silver compound that has been produced in an electrolytic cell 1, the solution supplied to a dissolving tank 11 in which glass fiber filter elements have been installed is discharged through porous filtering mediums 14, so that the glass fibers dispersed in the inside of the solution are laminatedly attached on the filtering surfaces of the porous filtering mediums 14, and the dissolution is advanced by passing the solution through the attached layers. Further, the free solution contained in the glass fiber is sucked so that the porous filtering mediums 14 are separated from the vessel 18 to remove the attached glass fibers.  Thus, the flow passage of the electrolytic cell or the like is prevented from being clogged by the glass fibers, and also the need of the transfer of the solution of low fluidity in which glass fibers are dispersed can be dispensed with.

Abstract: PURPOSE:To shorten the time required for starting of engagement of frictional engaging elements by changing a target idle engine speed to a large value when an engine is shifted from a stopping range to a travelling range, and returning the target idle engine speed after the change to a value before the change when the engagement of the frictional engaging elements is started. CONSTITUTION:When an engine is shifted from N or P range at a point P1, an oil passage through which oil pressure is supplied to frictional engaging elements of an automatic transmission 3, is opened. Time T0 is the mechanical operation lag time. On the other hand, when control for changing a target engine speed to 7000rpm is started to increase the engine speed NE, the delivery of a pump is increased to fill the oil passage in a short time. After the time T2 required to fill the oil passage has elapsed, the engagement of the frictional engaging elements is commenced, the turbine rotating speed NT of a torque converter 4 begins to reduce, and as a result, control for changing the target idle engine speed is stopped at a point P2 to return the target idle engine speed to 500rpm.

Title: Cryptographic communication method for facsimile equipment
Inventor: SHIBATA KOICHI
IPC: H04L9/08
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To make an enciphered sentence difficult to be deciphered by a third party by measuring the time interval of a predetermined operation such as an inputting interval of the facsimile number of a transmission destination, for example, based on transmitting operation performed by a user at the transmission side facsimile equipment and generating a cryptographic key based on the measured time interval. SOLUTION: Binary data outputted from a reading part 11 are encoded by an encoding part 15 and enciphered by a control part 1 while using a cryptographic key. When the FAX number of facsimile equipment on the opposite side is inputted from an operating part 13, the control part 1 samples the dialing interval of pressing the FAX number and generates a cryptographic key based on the sampled dialing interval. Thus, since the cryptographic key is frequency changed even without performing any special operation by a user, the enciphered sentence is made difficult to be deciphered by a third party and the cryptographic key can be generated without requiring any special hardware.
