Title: Digital radio transmission system
Inventor: KURAHASHI TOMOYUKI
IPC: H04B3/462
Filed: 1991-01-11
Abstract: PURPOSE:To easily specify a fault station and a fault circuit in a short period at the time of occurrence of the faults in an equipment. CONSTITUTION:When a remote monitoring (telemetering) is performed for the station condition for each station of repeater station devices R1, R2 and a terminal equipment T2 opposing to a terminal equipment T1, for instance, of terminal equipments T1 and T2, the transmission request signals are transmitted to each station of R1, R2 and T2 from the terminal equipment T1 with the use of lines 201 to 203. The station R1, R2 and T2 receiving the transmission request signals returns the station condition to the terminal equipment T1 with the use of the reverse lines 204 to 206. At this point, when the frame synchronous signals transmitted from the sending-end station are not detected in the receivers of the terminal equipments T1, T2 and the repeater station devices R1, R2, the conditions of the transmitters and receivers of its own station is transmitted to the opposing sending-end station with the use of inverse lines, regardless of the existence of the transmission request signal from the opposite sending-end station.

Title: Collating method for identification number
Inventor: OGAWA ATSUSHI
IPC: G06Q40/00
Filed: 1990-01-08
Abstract: PURPOSE:To relieve the invalidity of an identification number caused by a slight erroneous input of a legal user of the identification number by storing a discrepancy number, and not counting it as the number of times of discrepancy or counting it as the number of times of discrepancy being under once, when the same number as this discrepancy number is inputted again. CONSTITUTION:In the case an identification number obtained by a magnetic card and the number inputted from a key pad 11 do not coincide with each other, a CPU 2 stores the number inputted by the key pad 11 in a discrepancy number temporary storage memory 20. In the case the identification number does not coincide with the number inputted from the key pad 11 for a second time, it is compared with the discrepancy number inputted for a first time, and when they coincide with each other, a result of decision (discrepancy) of a first time is decided to be an erroneous input having no evil intention such as a mere misunderstanding of a legal user, and it is requested to the user to input the number over and over again. In such a way, the case of such an erroneous input as the legal user inputs an identification number of another magnetic card which he owns can be protected.

Filed: 1999-01-08
Abstract: PROBLEM TO BE SOLVED: To provide an optical material having good optical characteristics, favorable solvent resistance, shock resistance and weather durability by forming the optical material of a polymerized hardened material obtained by polymerizing a polymerizing composition containing a specific radial polymerizing compound. SOLUTION: This material is obtained by a polymerized hardened material obtained by polymerizing a polymerizing composition containing a radical polymerizing compound having a thiocarbamate bonding obtained by previously reacting a tetrathiol compound expressed by a formula and a compound having a isocyanate radical and an acryloil radical in a molecule. In the formula, k, m, n indicate independently integers of 1 to 3. As such a radical polymerizing compound having a thiocarbamate bonding has a high content of thiocarbamate bonding, the refractive index and the Abbe number are heightened so that the refractive index and the Abbe number of the produced optical material are also heightened.  Since it has four radical polymerizing groups and has self-crosslinking property, even if a cross-linking agent is not added as a sub- component, high solvent resistance and high heat resistance are given to the optical material.

Title: Optical recording medium
Inventor: ARAKAWA SEIICHI
IPC: G11B7/246
Filed: 1988-01-09
Abstract: PURPOSE:To enhance light resistance, productivity, optical characteristics or the like by using a chroconium coloring matter having a t-butyl-substd. nitrogen- containing heterocyclic ring at either end of its molecule as a recording material. CONSTITUTION:A recording layer comprises a chroconium coloring matter of formula I, wherein the heterocyclic ring at either end is a t-butyl-substd. nitrogen-containing heterocyclic ring, and each of R1 and R2 is a substd. or unsubstd. alkyl, cycloalkyl, allyl, substd. or unsubstd. aralkyl or substd. or unsubstd. aryl. The chroconium coloring matter, having a 5-membered ring at a central linking portion thereof, is structurally stable, and expansion of a delocalization region of pi-electrons causes a shift of absorption to the longer wavelength side, thereby enabling application of the coloring matter to a semiconductor laser with a wavelength of, for example, about 830nm. The solubility of the chroconium coloring matter depends heavily on substituent groups on the heterocyclic rings (nitrogen-containing heterocyclic rings) at both ends, and, particularly, introduction of t-butyl groups contributes effectively to enhancement of solubility of the coloring matter in general-purpose solvents.
