Title: Lead-acid battery
Inventor: TOYODA MIYUKI
IPC: H01M4/62
Filed: 1990-11-27
Abstract: PURPOSE:To restrain self-discharge operation by adding metal tin or tin compound into positive electrode active material and adding alkaline metal ions into electrolyte, in a battery using Pb-Sb group alloy lattice. CONSTITUTION:In a battery for which metal tin or tin compound as positive electrode active material with tin element added to lead 0.01%-5% by mol therein is filled into Pb-Sb group alloy lattice, alkaline metal ions are additionally contained in electrolyte. If the Pb-Sb group alloy lattice is used, the elusion of Sb in the lattice when formed, charged and left and the subsequent movement to a negative electrode can be restrained by adding metal tin or tin compound into positive electrode active material. Also, such effect is improved by containing alkaline metal ions in electrolyte. It is thus possible to restrain self- discharge operation in a battery using Pb-Sb group alloy lattice.

Title: Electronic preserving method and device for guaranteeing originality and computer readable recording medium
Inventor: KANAI YOICHI
IPC: G06F21/64
Filed: 1999-11-18
Abstract: PROBLEM TO BE SOLVED: To prevent the complication of the procedure of the update or reference of a document in a device for preserving a composite document so that the originality can be guaranteed. SOLUTION: At the time of receiving a plurality of contents files of an original to be newly prepared from the outside, a contents file hash value is calculated (S5). The hash value of data attribute information based on a new original identification number, data information, and contents file information is calculated and recorded (S8). Then, the hash value of the access log of the original is calculated and recorded (S10). Also, the hash value is calculated and enciphered based on hash collection obtained by combining the contents file hash value, the data attribute information hash value, and the access log hash value so that a hash file MAC can be prepared (S11). The hash collection is combined with the hash file MAC, and recorded in a large capacity storage medium (S12).  Then, a preserved data list entry is prepared by combining the original identification number, the original attribute, the preparation date information, and the hash file MAC, and added to the large capacity storage medium (S13) to end the processing.

Title: On-vehicle communication antenna
Inventor: ARAKI HIROSHI
IPC: H01Q1/02
Filed: 1990-11-30
Abstract: PURPOSE:To prevent the quality of transmission data from deteriorating due to multi-pass fading by providing a shield plate to suppress a ground-reflected wave in the periphery of a simplex radiant element resonant with a communication frequency, and adjusting radiant directivity. CONSTITUTION:This antenna is comprised of the radiant element 1, a feeder part 2, a ground plate 3, the shield plate 4, a short-circuited plate 5, a case 6, and a feed cable 7. The shield plate 4 is a conductor plate which shields a reflected wave from the ground, and is connected to the periphery of the ground plate 3. The wavelength of a quasi-microwave is short compared with that of a VHF wave or a UHF wave, therefore, it is provided with high rectilinear propagation property, and since the antenna height of an on-vehicle antenna is low, it receives the high influence of the reflected wave from the ground, i.e., a road. Therefore, the influence of the ground-reflected wave is reduced by providing the shield plate 4 and directing the radiant directivity of the on- vehicle antenna upward. Thereby, it is possible to reduce the influence of the multi-pass fading due to the ground-reflected wave, and to stably secure transmission quality with simple structure.

Title: Fingerprint collation method
Inventor: KUSANO HIROYUKI
IPC: G06T7/00
Filed: 1992-12-11
Abstract: PURPOSE:To identify a person himself even if a collation coincident rate is low by shifting a system to a relief mode when collation becomes non-coincident, sequentially inputting fingerprints to a fingerprint input part as to plural fingers, reducing a collation threshold and sequentially collating the fingerprints. CONSTITUTION:At a regular mode, the fingerprint of a first finger inputted by a fingerprint input part 1 is collated with the fingerprint of the first finger, which is registered in a fingerprint registration part 2, in a collation part 3 so as to identify the person himself. When only a fingerprint picture whose collation coincident rate is low can be obtained, the system shifts to the relief mode. At the relief mode, collation is executed by a value lower than the threshold at the regular mode. In such a case, the input fingerprint is sequentially collated with the registered fingerprint on the plural fingers. When the collation of all the fingerprints from the first finger to the M-th finger coincides, the person himself is identified. In such a case, security similar to the case of the regular mode can be maintained since the fingerprints of the plural fingers are collated even if the collation threshold is lowered.
