Filed: 1999-09-22
Abstract: PROBLEM TO BE SOLVED: To provide a new ciphering method for an open key ciphering system whose safety is based upon the arbitrary selection of one combination of open keys out of very many combinations of open keys. SOLUTION: Multiple open keys having random number terms embedded by divided plaintexts are prepared in a database 10 and arbitrary open keys are selected out of the prepared open keys for respective divided plaintexts and used to generate a ciphertext C. Here, the safety is based upon the free section of a desirable combination of open keys out of many open keys, in other words, many combinations of open keys which can be selected.

Abstract: PROBLEM TO BE SOLVED: To provide a cable with a shield tube which enables weight reduction and cost down while preventing the exfoliation or damage of a metallic layer for electromagnetic shielding. SOLUTION: A metallic tape 12, where a resin anchor layer 14 is stuck to one side and a resin coating layer 15 is stuck to the opposite side, is wound in a spiral form around a winding core so that the resin coating layer 15 may be a lower layer. At this time, a gap is provided for every winding, and the second layer of metallic tape 13 (the same form as 12) is wound so as to stop the gap. Forming a resin sheath layer 11 thereon will fuse and spread the resin anchor layer 14 and the resin coating layer 15, and lay the metallic tapes 12 and 13 on top of each other at both edges, and they will be fixed in condition that electric continuity is possible. After this, removing the winding coil will complete a shield tube for a cable.

Title: 2-wire/4-wire lan converter
Inventor: MATSUMOTO YASUSHI
IPC: H04L12/28
Filed: 1990-10-08
Abstract: PURPOSE:To attain inter-communication by matching of the electric characteristic and the communication system between a 2-wire LAN and a 4-wire LAN and to attain 2-way collision communication by detecting collision. CONSTITUTION:When a signal is sent from a 2-wire LAN to a 4-wire LAN, a 2-wire/4-wire conversion section 11 outputs the signal inputted from the 2-wire LAN to only to an output line of the 4-wire LAN. Moreover, when a signal is sent from the 4-wire LAN to the 2-wire LAN, a signal from the input line of the 4-wire LAN is outputted to both the output line of the 2-wire LAN and the 4-wire LAN. Thus, inter-communication is implemented between the 2-wire LAN and the 4-wire LAN. Furthermore, a collision detection matching section 12 outputs a JAM signal to both output lines of the 2-wire LAN and the 4-wire LAN when communication enters from the 2-wire LAN while the 4-wire LAN sends a signal to the 2-wire LAN and a reception signal is detected to the input line from the 4-wire LAN while the 2-wire LAN sends a signal to the 4-wire LAN.

Title: Halogen lamp
Inventor: WATANABE TSUTOMU
IPC: H01K1/32
Filed: 1987-10-28
Abstract: PURPOSE:To sharply decrease infrared rays which enter a sealing part so as to lower the temperature of a molybdenum introduced foil by forming an infrared ray reflecting film opposed to a filament at the central part of a bulb and an infrared ray transmitting film on a glass near the sealing part of the bulb. CONSTITUTION:A visible light transmitted infrared ray reflecting film 6 (infrared ray reflecting film) is formed at the central part of a bulb oppositely to a filament 5 and a visible light reflecting infrared ray transmitting film 7 is formed on a glass near the sealing part 2 of a bulb, whereby infrared rays which entered the bulb end are released to the outside so as to prevent it from entering the sealing part 2. That is, the infrared ray transmitting film 7 has a property of transmitting infrared rays a lot and as compared with the smooth face of glass the entire reflection of the infrared rays is small, so the infrared rays that entered the bulb end mostly pass through the infrared ray transmitting film 7 and are released to the outside, and the reflection amount of the infrared rays is decreased as compared with the case where element glass is used, not to mention of comparison with that provided with the infrared ray reflecting film 6 at the bulb end 6. Hereby, the entry to the sealing part decreases and the temperature of a molybdenum introduced foil can be lowered.

Title: High speed reading circuit
Inventor: SON NIYUUSEN
IPC: G11C17/18
Filed: 1988-10-28
Abstract: PURPOSE:To read out a memory with high sensitivity and at a high speed in a simple constitution by attaining the precharge function of a read line and the sense function via the same amplifying part and an action point setting part. CONSTITUTION:A read line 61 of a memory 60 is precharged by an amplifying part 56, and an action point setting part 58 sets the precharge voltage of the line 61 at a level slightly shifted from an action point near that of the part 56. The high gain is secured for the precharge voltage since this voltage is set near the action point. Then the part 56 can detect the minute change of the voltage of the line 61 at a high speed when the memory 60 is read out. In the case the line 61 is not discharged to the earth voltage by a control signal 64 received from an address decoder 53, the logic value 1 is read out. While the logic value 0 is read out in the case the line 61 is discharged to the earth voltage by the control signal 64. Thus the precharge function of the line 61 and the sense function are attained in the same constitution. As a result, the memory can be read out with high sensitivity and at a high speed in a simple constitution.

Abstract: PURPOSE:To perfectly eliminate accumulated error and provide a display output of precise multi-rotating position at the time of converting the incremental value pulse output of a detector into a position display signal of a set scale. CONSTITUTION:A two-phase pulse signal A from an encoder 1 is converted into an up down pulse signal B by a signal converting part 2 and integrated by a digital counter 3 to form a binary signal C. Thereafter, it is multiplied by an arithmetic value S by an EP-ROM 4 to form a correction signal, and a corrected two-phase pulse signal E is outputted by a pulse converting part 5.

IPC: F01N3/28
Filed: 1991-10-18
Abstract: PURPOSE:To provide a method for preventing internal surface (overall surface corrosion, pitting, crevice corrosion) of respective members after a converter in the exhaust system of an automobile. CONSTITUTION:Platinum group metal catalyst dust used in a converter disperses and sticks on the internal surface of respective members in an exhaust system after the converter by exhaust gas and accelerates erosion.
