Title: Radio lan system
Inventor: KAMITO TAKEYA
IPC: H04W48/02
Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To suppress deterioration of transmission/reception throughput by regulating the connection to a roaming station when a connection request exceeding a previously decided number is made to an access point from the roaming station in a service area managed by an arbitrary access point among plural access points. SOLUTION: When the power of the roaming station 1 is turned on and it roams from out of the service area, the connection request containing a self-identifier is transmitted to the access point 2. The access point 2 adds an access point number of the connection request and transmits it to a controller 3. The controller 3 stores the number of connection possible stations at every access point 2 in a storage device 31 and executes recognition processing of the connection request. When connection is possible, a connection request reception is returned to the access point 2, and connection request denial when connection is denied. The access point 2 returns it to the roaming station 1.

Abstract: PROBLEM TO BE SOLVED: To execute the direct control in a digital circuit without requiring the control of plural voltages by providing a selection period when scanning signals and display signals consisting of plural voltage levels are subjected to line sequential driving and a regulation period when the variations in the potentials generated by display content differences are regulated. SOLUTION: The scanning signals of scanning electrodes C1, C2 are subjected to the sequential selection of the signals consisting of only the two potentials of power-supply voltage levels VDD and 0 during the time of the section period ts, then to the basic line sequential driving in the selection period ts at the time of impressing the segment electrodes S1 to S4 and scanning electrodes C1, C2 from a liquid crystal driving circuit 7. Only the two potentials of the power-supply voltage levels VDD and 0 are thereafter changed by pixels which drive the segment signals of the segment electrodes S1 to S4 as well while the scanning signals of the scanning electrodes C1, C2 progress. The variations in the potentials generated by the display content differences are regulated in the next regulation period ta, by which the necessary voltage differences are applied to the desired segments.

Title: Frame synchronizing circuit
Inventor: SASAKI KATSUHIRO
IPC: H04L7/08
Filed: 1990-08-13
Abstract: PURPOSE:To decrease the discrimination time for out-of synchronism of an auxiliary signal frame by inputting a synchronization discrimination result signal being a main digital signal of a 1st frame synchronizing circuit also to a 2nd frame synchronizing circuit. CONSTITUTION:A 2nd frame synchronizing circuit 103 establishes a frame synchronization of an auxiliary signal 14 and sends a discrimination result signal 15, receives a discrimination result signal 16 of a 1st frame synchronizing circuit 101 and enforces the discrimination result signal 15 of the 2nd frame synchronizing circuit 103 to frame out of synchronism when the discrimination result signal 16 is at frame out of synchronism. That is, when frame synchronization of the main digital signal is out of synchronism, since out of synchronism is found out without need of confirmation of frame out of synchronism of the auxiliary signal, the discrimination result signal 15 is forcibly brought into out-of synchronism.

Title: Network configuration management system
Inventor: SEKINO HIROSHI
IPC: H04L12/42
Filed: 1991-08-26
Abstract: PURPOSE:To grasp the configuration state of nodes accurately by recognizing missing of a node address due to defect or duplicated node address. CONSTITUTION:A master node 21 sends an own node address reply request frame to all nodes used to request of information of node addresses 1-6 of each node in terms of multiple address communication when the addresses of the nodes subscribing to the network and its configuration are to be grasped. Nodes 22-26 not being a master node receive the own node address reply request frame and send their own node address notice frame in which the transmission address is kept to be the master address and their own node addresses are stored in an information part of the frame. When the master node 21 receives the frame and it is the own node address notice frame, the master node 21 extracts the node address from the information part in the frame to grasp the configuration of all the nodes.

Title: Method for absorbing moisture composite material
Inventor: MOMOSE YUTAKA
IPC: G01N33/00
Filed: 1999-07-28
Abstract: PROBLEM TO BE SOLVED: To absorb the moisture of a composite material in a short time and form a moisture-absorbed state which is equivalent to the composite material under an actual environment, by absorb the moisture of the composite material in a pressure container at high temperature, high humidity and high pressure. SOLUTION: The moisture of a composite material is absorbed in a pressure container at high temperature and high pressure, so that a prescribed quantity of moisture can be removed in a short time. In this case, high pressure is selected to be a range of 1,400-5,000 hPa, preferably, 1,400-3,000 hPa. A composite material, having moisture absorption amount of equal level to the composite material left for a prescribed year, e.g. 25 years under a high-pressure environment can be obtained in a short time with the use of the pressure container. However, if the sheet thickness of the composite material increases, moisture absorption distribution in the thicknesswise direction becomes different from the composite material under actual environment, even when the moisture absorption amounts are equal.  For preventing this, the environmental conditions in the pressure container are changed in accordance with a preliminarily set time table so as to equalize moisture absorption distributions. Even the strength of the composite material of a large sheet thickness can be evaluated correctly accordingly.

Abstract: PROBLEM TO BE SOLVED: To continuously detect a preceding vehicle even if the absolute speed of the preceding vehicle drops by estimating the present position of an object based on the position of the detection object when the object detected as vehicle cannot be detected as the vehicle. SOLUTION: A vehicle judgment means 26 judges whether a mobile object positioned in front is a vehicle or not by using the absolute speed of the front object, which is detected by a front object absolute speed detection means 22.
