Title: Ring node and method fro transfer of communication circuit
Inventor: UIRUHERUMU KUREEMAA
IPC: H04Q11/04
Filed: 1993-05-24
Abstract: PURPOSE: To provide a system for continuing the connection of a communication circuit under the existence of a failure ring node in a bi-directional line exchange ring transmission system. CONSTITUTION: The communication circuit is transferred by setting a bi- directional communication circuit in the alternate ring node. One example of transfer is to transfer the communication circuit terminating at the failure node 103 by not squelching it on one prescribed side where it is normally to be squelched at a node adjacent to the failure node 103 but squelching the communication circuit terminating at the failure node 103 by the node adjacent to the other side. Thus, the communication circuit which can be transferred is loop back-exchanged and is transferred to the alternate node. Then, the alternate node directly intercepts the transfer communication circuit. It is executed by giving information containing the whether the alternate node which identifies all the active communication circuits in the ring and which is to be transferred exists or not to the node.

Title: Opening and closing adjusting device
Inventor: YAGI KATSUMI
IPC: E05F5/10
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To prevent a door from being closed suddenly by providing a plug energized by a spring in an air damper type opening and closing adjusting device, whereby when a gust or the like is applied, an exhaust passage is closed by the plug, and air is compressed by a piston. SOLUTION: An opening and closing adjusting device 1 is provided between an opening and closing member of a door, a window, a top cover or the like and a skeleton to adjust the opening and closing speed. In the case of normal door closing operation, when a piston 5 is pressed at a designated speed, air in a cylinder is discharged through a gap G and a groove 10a from an exhaust port 7a, so that the door is closed quietly. When the door is quickly closed by unexpected external force of a gust, a child or the like, the piston 5 is quickly moved to suddenly increase the air pressure in the cylinder, so that a plug 9 is pressed to a terminal member 7 against the force of a spring 8. Then a groove 10a is closed so the the door can be prevented from being suddenly closed by the air pressure in the cylinder. Thus, the door or the like can be surely prevented from being suddenly closed.

Title: Nonvolatile semiconductor memory
Inventor: ISHII KAZUTOSHI
IPC: H01L29/78
Filed: 1987-06-08
Abstract: PURPOSE:To write in a memory by high breakdown strength at a high speed by forming a second diffused region having lower impurity concentration than that of a first diffused region around the first region directly under the tunnel oxide film of an EEPROM. CONSTITUTION:The impurity concentration of a first diffused region 12 directly under a tunnel insulating film 6 is increased, and a second region 11 having low impurity concentration is formed on the periphery of the region 12. An EEPROM having the regions of different impurity concentrations formed in this manner can suppress a surface breakdown near the surface of a semiconductor substrate 1, and set the surface of the diffused layer directly under the insulating film to the impurity concentration which is not depleted. Accordingly, since a writing voltage is mostly applied to the insulating film, writing efficiency is enhanced to write at a high speed.

Title: Level shift circuit
Inventor: IGARASHI HATSUHIDE
IPC: H03K19/00
Filed: 1983-08-05
Abstract: PURPOSE:To obtain a stable level shift circuit by providing a power supply switch function to a level shift circuit so as to minimize extremely a peak current value produced at the inversion of operation. CONSTITUTION:Transistors (TRs) M11-M16 having a threshold voltage of VTN is not turned on but in inoperative state until a power supply (-VD/2) is exceeded. Thus, since the TRs M11, M12 at drive side are in operating state when a threshold voltage of the TRs M13, M16 is larger than a threshold voltage of the TRs M11, M12, the circuit is not subject to the fluctuation of a node potential different from a conventional circuit. Since only a voltage (-VD/2) is applied to a gate of the TRs M15, M16 when the threshold voltage of the TRs M11, M12 is larger than that of the TRs M13-M16, a peak current is less than the current of a conventional circuit thereby attaining stable level shift operation.
