Title: Frequency fluctuation correction device
Inventor: NAKAJIMA SHIGEO
IPC: H04L27/22
Filed: 1991-09-09
Abstract: PURPOSE:To correct a frequency fluctuation of a reception signal having a large frequency fluctuation by applying multiplication, averaging and subtraction to a modulation phase of a reception signal wave estimated from an output signal of a demodulation circuit so as to add a simple device to the demodulation circuit. CONSTITUTION:Signals branched into two from an inputted reception signal wave, an output of a fixed oscillator 4 and an output therefrom via a pi/2 phase device 3 are respectively detected by phase detectors 2-1,2-2 and the result is converted into a base band signal each. Each output is given via low pass filters 5-1,5-2, A/D converters 6-1,6-2 to a modulation phase estimate device 8, in which a modulation phase of the reception wave is estimated. A frequency fluctuation correction circuit 9 branches the signal from the modulation phase estimate device 8 into two, the one signal is doubled by a doubler 10, its output via a delay device 11 and its output not therethrough are subtracted by a subtractor 15 and the result is averaged by an averaging circuit 13. Moreover, the other signal is delayed at a delay device 14 by number of data used for the averaging. The output of the delay device 14 and an output of the averaging circuit 13 are subtracted at a subtractor 15, and the result is used to correct phase deviation due to the frequency fluctuation.

Title: Photocatalystic hydrophilic member
Inventor: HASHIMOTO KAZUHITO
IPC: B01J35/02
Filed: 1997-09-04
Abstract: PROBLEM TO BE SOLVED: To improve a hydrophilization velocity corresponding to the photo- excitation action of a photocatalyst by a method in which a layer containing photocatalytic oxide particles is formed on the surface of a substrate, and the particles are fixed to expose oxygen atoms existing in the bridging sites in the photocatalytic oxide. SOLUTION: A layer containing the particles of photocatalytic oxide such as an anatase-type titanium oxide and a rutile-type titanium oxide is formed on the surface of a substrate. In order to expose oxygen atoms existing in the bridging sites in the photocatalytic oxide, the particles are crystallization- oriented to be fixed on the surface. In the fixing, for example, a hot-press baking method at a prescribed temperature is used after ion-beam deposition. When a coating film is formed on the surface of a member by such a method and others, the surface becomes hydrophilic corresponding to the photo- excitation of the photocatalyst. In this way, besides cloud preventive effects and surface purifying effects, antistatic effects and others can be demonstrated.

Title: Optical information recording medium
Inventor: OTAGURO KUNIHIKO
IPC: C09B23/00
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To prevent light deterioration during the long preservation period of time by allowing the absorption spectrum curve of a recording organic coloring matter and the absorption spectrum curve of an organic metal coloring matter compound to intersect to each other, and permitting the organic metal coloring matter compound to have the largest absorption wave length at its long wave length side from the largest absorption wave length of the recording organic coloring matter. SOLUTION: When a cyanin coloring mater and an organic metal coloring matter compound are combined, respective absorption spectrum curves intersect to each other; moreover, both the coloring matters can be selected such that the largest absorption wavelength of an organic metal coloring matter compound is situated at the long wave length side from the largest absorption wave length of the cyanin coloring matter. For this reason, the cyanin coloring matter acts to transfer a part of the absorption light energy to the organic metal compound having the largest absorption at the long wave length side, thereby restraining a decoloration being the light deterioration of the cyanin coloring matter for transfer.  Moreover, since the organic metal coloring matter compound has the largest absorption at its long wave length side, the transferred light energy is absorbed at the long wave length side, and the light energy absorbs a low level energy in accordance with this.

Abstract: PURPOSE: To distribute and authenticate a key by using an adapter having a concealed key and an individual identifier, and storing an encryption program. CONSTITUTION: Adaptors, each of which stores a common key Km and an individual identifier UA, are arranged in a network (radio) manager, base stations RS and remote stations. The key Km and a UA parameter are selected on the 1st base station adaptor and the initial introduction of a check key is started. Then the base station adaptor produces a trigger so as to generate a network key (Knet) and a backbone key (Kb) from a spare key (K1) in accordance with a specific procedure. The key (Kb) is sent and stored in the radio manager. A remote station adaptor reads out the UA from its own PROM and selects a corresponding name by a previously determined method. The name of the remote station and an address mark are transferred to the manager.  The manager inspects data related to the introduced base station and provides the UA address and name information of the received remote station to the base station. Consequently the distribution and authentication of the key can surely be executed.
