Title: Data communication network
Inventor: RICHIYAADO JIEIMUSU UESUTOMOA
IPC: H04J14/02
Filed: 1990-10-11
Abstract: PURPOSE: To maintain the accurate time sequence of a signal by constituting a frame of plural messages outputted from respective terminals, receiving these messages in parallel and ordering messages received in previously determined order in the frame in the receiving order of the frame in each terminal. CONSTITUTION: Many identical node devices 20 are mutually connected by optical fiber transmission lines 21 through a common passive optical star coupler 22. When the system is driven, the frames of all nodes are synchronized with a frame outputted from a reference node independently of their phases. Each node having a transmitting public writing part transmits the writing part to its own optical frequency on the data packet of a work frame. Each frame carries data from all system nodes in parallel and provides effective application to system band width. Each received data packet in the frame is processed as data received in the same order as the numbering of wavelength. Each node is held at the fixed time order from other nodes of the network. Since the frame is shorter than transfer time, the high resolution of a time stage can be attained.

Filed: 1989-10-20
Abstract: PURPOSE:To execute a reserving operation through one touch by providing a reserving switch and a reserving execution switch. CONSTITUTION:The reserving SW 9 and the reserving execution SW 10 are added, and a control data is usually sent by a control part (micro-computer) 2 to an individual source control circuit 5 in order to make an operation mode corresponding to a state of a usual operation SW 1, and also a data for displaying the operation mode is sent to a display 4.

Filed: 1991-10-22
Abstract: PURPOSE:To obtain a center ignition powder tube free from the lag of ignition time and resistant to degradation such as moisture absorption by placing a coating layer of nitrocellulose and black powder on the inner surface of a cylindrical supporting tube composed of a completely burning material. CONSTITUTION:The objective center ignition powder tube has a double layer structure composed of a cylindrical supporting tube 1a made of a completely burning material and an igniter coating layer 1b (inner layer) composed of a mixture of nitrocellulose and black powder and applied to the inner surface of the supporting tube. It may have a three-layer structure having a layer (outer layer) composed of a roll-formed sheet 1c of nitrocellulose and a plasticizer applied to the outer surface of the double layer structure or a mixture of nitrocellulose and black powder applied to the double layer structure. The mixing ratio of the nitrocellulose to the black powder is 1:(9-2). When the mixing ratio of the black powder is larger than 1:9, the non-uniform application to the cylindrical tube or the separation of the coating layer from the tube may occur. If the mixing ratio is smaller than 1:2, the ignitability is deteriorated to an undesirable level.

Title: Convergence correcting method
Inventor: UEHARA YUTAKA
IPC: H04N9/28
Filed: 1989-10-20
Abstract: PURPOSE:To reduce labor and time required for actual correction by using a correction waveform obtained for an optional one set as common correction data. CONSTITUTION:The volume group 2 of a first television receiver is adjusted correctly so that misconvergence is eliminated, and a correction signal is formed. Further, the correction signal obtained in the adjustment of this volume group 2 is converted into digital quantity by an A/D converter 11, and is stored as the correction data in a memory 12. Then, henceforward, as occasion demand, by regenerating the correction signal from the correction data, and flowing it as a correction current to a deflecting yoke 4, the correction of the first set is completed. As for the receiver after the second one, the correction data stored in the memory 12 of the first receiver is stored as the common correction data as it is in the memory 12, and simultaneously, the adjusting positions of the volume group 2 are made coincide with the first set. Thus, the convergence correction in a large number of video apparatuses can be easily executed.

Title: Semiconductor memory and manufacture thereof
Inventor: SUNAMI HIDEO
IPC: H01L27/108
Filed: 1997-10-07
Abstract: PROBLEM TO BE SOLVED: To provide a superior long-term memory hold property and high-speed stable RAM operation by setting the memory between a perfect nonvolatile memory and a DRAM according to the restricting proportion of the leak current and sub-threshold current. SOLUTION: When all powers are turned off, word lines, data lines, sense lines, and control lines all become at floating 0 V. If no leakage current flows from the substrate or the threshold voltage of write transistors is sufficiently high, they will hold charges at memory nodes, acting as a nonvolatile memory. According to the restricting proportion of the leakage current and sub-threshold current, the memory can be set between the perfect nonvolatile memory and a normal DRAM. If no barrier film 12 exists, it must be refreshed in a manner similar to the DRAM cell. When this layer 12 is as thick as a flash memory, a nonvolatile memory can be attained. Thus desired functions can be attained, depending on the thickness of the barrier film 12 or barrier film substrate 11.
