Title: Secret communication system
Inventor: SHIBUYA EIICHIRO
IPC: H04L9/16
Filed: 1987-03-26
Abstract: PURPOSE:To sufficiently secure the secrecy of communication information by a method wherein a key is generated at each subscriber's terminal, and a central unit and the subscriber's terminal encode a communication information to be transmitted by means of an exclusive logical sum processing based on said key. CONSTITUTION:From a subscriber's terminal, an encoding key for the secrecy generated by an encoding key generation circuit 18 is transmitted to the central unit, and the information signal to be transmitted to the central unit is encoded through the exclusive logical sum operation in an exclusive logical sum circuit by using a scramble data generated based on the coding key. At the central unit, the encoding key transmitted from the terminal is stored in a encoding key holding circuit 27; the exclusive logical sum circuit decodes and fetches the information signal encoded and transmitted from the subscriber's terminal by using a scramble data generated based on the encoding key, and further, the information signal is encoded through an exclusive logical summing then is transmitted to the subscriber's terminal. In such a way, the secrecy of a communication information can be effectively attained.

Title: Separating device for paper leaf
Inventor: ISHIGURO AKITO
IPC: B65H3/08
Filed: 1981-05-15
Abstract: PURPOSE:To obtain the stable separation of a paper leaf at a high speed by setting the swaying angle of a sucker greater than the turning angle of the paper leaf to be bitten in a roller. CONSTITUTION:A sucker 2 is pushed to a paper leaf 1 at its suction port. When negative pressure is supplied to the suction port by the work of a bearing valve 3B, the sucker 2 absorbs one sheet of the paper leaf 1, and swayed round its shaft 2A. It holds down one end of the paper leaf 1 by its foot, turns another end, and brings the former end of the paper leaf 1 to the joining point of bite-in rollers 4 and 5. It is furthermore swayed and stopped. At this position, its swayed angle is desirable to be a little greater than the turning angle of the paper leaf 1 to be bitten in the rollers 4 and 5. At this stopping position, the sucker 2 is connected to the open air by the work of the bearing valve 3B. This construction permits to ensure the smooth separation of the paper leaf from the sucker, prevent the re-absorption, the abrasion of a cup-shaped ring, and the like, and obtain the high-speed separation.

Abstract: PURPOSE:To obtain a reformer having high reliability and capable reducing degree of negative pressure of an ejector by providing a piping for communicating to the neighbor of steam inlet of the ejector and the neighbor of raw material fuel inlet and bypassing a part of steam in the neighbor of inlet of raw material fuel. CONSTITUTION:When pressure of suction side of an ejector 5 becomes large negative pressure, difference between secondary side pressure of a reducing valve 9 and suction side pressure of the ejector 5 works as a driving force. Part of steam is bypassed through a flow rate limiting orifice 10 and bypass piping 8 to the suction side of the ejector 5, namely inlet side of raw material to control secondary side pressure of a valve 9 to the neighbor of atmospheric pressure. At this time, raw material flow rate and steam flow rate is subjected to flow rate control by signals of a transmitter 1 for raw material flow rate located on the upper stream therefrom and transmitter 6 for steam flow rate. Consequently, total flow rate is not changed. By bypassing a part of steam, driving side flow rate is decreased and suction side flow rate is increased and large negative pressure of sucking ability of ejector 5 is canceled.

IPC: G01M99/00
Filed: 1989-03-25
Abstract: PURPOSE:To enable highly-precise analysis of a phase change of an arbitrary frequency component contained in a function by determining the amount of the phase change by using a phase value of the phase change of a discrete change by using a phase value of the phase change of a discrete spectrum obtained from a plurality of times of discrete Fourier transforms. CONSTITUTION:A/D conversion of a vibration signal 5 inputted from a vibration signal input terminal 1 is conducted in an A/D conversion element 3, using as a sampling timing a pulse signal which is generated by subjecting a period signal 6 inputted from a period signal input terminal 2 to frequency division and multiplication, using a clock prepared by an oscillator as a reference clock. This conversion processing is repeated several times while fixing the length of a data group to be taken as an object of transform in each discrete Fourier transform and shifting the range thereof by a prescribed time. Utilizing a plurality of discrete spectrum data generated in this way, a phase change related to an arbitrary frequency component of an original vibration waveform is analyzed by a phase analyzing element 4. By this method, the phase change can be analyzed with high precision.
