Title: Switchgear
Inventor: SHIRAISHI MASAZUMI
IPC: H01H9/54
Filed: 1988-10-12
Abstract: PURPOSE:To diagnose the abnormality of a control circuit and a switching mechanism respectively by comparing the time to be elapsed before start of operation on and after reception of a switching command and the time to be elapsed before completion of operation on and after start of operation with normal times and managing the times. CONSTITUTION:A photo-optical switch is fixed to a circuitbreaker mechanism, and a time T1 to be elapsed before start of operation of the circuitbreaker on and after reception of a throw-in and trip signals from time measuring circuits 20, 21 which receive output from the photo-optical switch and a time T2 to be elapsed after start of operation of the circuitbreaker before completion of operation thereof are measured. Then the times T1, T2 are compared with normal times in a CPU 22 according to a time comparison program 23. If the time T1 is longer than the normal time, it is judged that the friction of grease has increased and that mainly the control circuit is abnormal. If the time T2 is longer than the normal time, it is judged that the mechanism does not function smoothly because of deformation or abrasion of the rotary section of the mechanism and that mainly the switching mechanism is abnormal. If both times T1, T2 are longer than the normal times, it is judged that aforementioned phenomena are combined.

Title: Layer short detector
Inventor: TAKAHASHI KENJI
IPC: G01R31/02
Filed: 1994-10-21
Abstract: PURPOSE: To detect the stage of partial discharge sustaining for a long term between the layers before making a transition to layer short by employing a variable voltage source as a test power supply and providing an electrode for scanning along the coil of an electric apparatus thereby detecting a high frequency potential oscillation caused by partial discharge of the electrode. CONSTITUTION: A test voltage equal to the interlayer withstand voltage is generated from a power supply 1 and applied directly to a coil 2 being inspected. If the interlayer insulation of the coil 2 is deteriorated, a partial discharge 3 takes place at a deteriorated part upon application of the withstand voltage. If an interlayer discharge 3 takes place, high frequency potential oscillation appears on a movable electrode 4 due to discharge 3 and the oscillation is introduced through a detection lead 11 to a partial discharge monitor 6. Consequently, the partial discharge part can be specified by scanning the electrode along the coil 2 using an insulation rod 10 and locating a position where the potential of the electrode is highest through the monitor 6.  Since the voltage is applied only across the coil and not applied to the ground insulation 9, the interlayer insulation can be tested separately from the insulation 9.

Title: Device for detecting operation of circuit breaker
Inventor: TOMINAKA SHIYOUZOU
IPC: H02J3/04
Filed: 1989-09-29
Abstract: PURPOSE:To reduce effects of power interruption by sending an a.c. signal to power supply lines through an antenna on the power source side of a circuit breaker, and receiving the signal through antennas on the power source and load sides so that the operation of the circuit breaker is detected according to the difference between the received signals. CONSTITUTION:When an a.c. signal is sent to a transmission antenna 5 from an a.c. signal source 8, the signal is induced in power lines 2 and load lines 3 if a circuit breaker 1 is closed. Therefore, the signals received by antennas 6 and 7 on the power source side and load side are equal in amplitude. When the circuit breaker is opened, on the other hand, the signal is induced only in the power lines 2, and only the antenna 6 on the power source side produces a signal with a predetermined amplitude. It is thus possible to detect the operation of the circuit breaker 1 according to the difference in amplitude between the signals at the antennas 6 and 7.

IPC: G06F21/60
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To disenable accessing to a common file unless a user is the normal one authenticated by means of a server by permitting a client side to succeed an authentication for an access request to the common file which is managed by means of the server even in an off-line state. SOLUTION: When the requested common file is transferred to a client for the access request to the comman file from the client to the server, the common file is enciphered 202 and transferred with acount information managed on the server. When access to the common file is permitted in the client, an authentication processing 32 consisting of at least a user name and a password is executed, the enciphered common file is decoded only when the user is authenticated to be the normal one 207 so as to make access possible. At the time of access completion, the decoded common file is enciphered so as to be preserved in the local storage medium of the client and the authentication processing is also executed at the time of requesting access to the preserved common file.

Abstract: PURPOSE:To improve mold releasability, to eliminate the deterioration of patterns by transfer, and to repeatedly carry out 2p transfer by providing a film of a metal or the oxide, nitride, or carbide of the metal on a 2p stamper. CONSTITUTION:After a resist is coated on a glass substrate 1, a spiral grooved pattern having 1mum width is scanned (exposed) by laser light and developed to form a resist pattern 2. A 2p resin 3 is coated on the resist pattern 2, a glass substrate 4 is placed thereon through a spacer having 40mum thickness, and then UV rays are irradiated to cure the 2p resin layer 3. The cured 2p resin layer 3 is released from the glass substrate 1 along with the glass substrate 4. Since the resist pattern 2 is simultaneously released along with the 2p resin layer 3, the resist pattern 2 is removed from the 2p resin layer 3 with a solvent. Then chromium is deposited in vacuum in 10-30nm thickness on the surface of the 2p resin layer of the 2p stamper consisting of the 2p resin layer 3 and the glass substrate 4 to obtain the protective and release-promoting film 3, and the surface of the chromium film 3 is treated with oxygen plasma to enhance the releasability.

IPC: H01J21/06
Filed: 1990-09-27
Abstract: PURPOSE:To enhance density of emitted electrons by forming one bulkhead with an insulating film formed between a conductor and the first metal film and another bulkhead between the insulating film and the second metal film, and applying a positive bias voltage to the second metal film. CONSTITUTION:The first bulkhead is formed with a SiO2 film 2 which is formed between a base board 1 made of conductor and the first metal film 3, and a vacuum part which is formed between the first and the second metals 3 and 6 becomes the second bulkhead and the first metal film 3 becomes a potential well. A positive bias voltage from a power supply 7 is applied to the second metal film 6 and a resonant state, in which the first insulating film 2 and a vacuum level act as a barrier, is generated. Electrons escaped from this resonant level reach the second metal film 6. The passing probability of electrons becomes 1 because the electrons reach the second metal film 6 passing through the resonant level. As a result, the current density can be enhanced.

Filed: 1984-12-06
Abstract: PURPOSE:To prevent the loss of tokens as well as system faults by replacing the parameters according to whether an ACK is sent back or not and according to the information obtained by monitoring plural input control parameters. CONSTITUTION:The packets to be transmitted are stored in a buffer 101 to be sent to a channel and also stored temporarily in a retransmission device. An ACK generator 108 produces ACKs when the packet addressed to the generator 108 itself from a channel is correct. Then the produced ACK is supplied to the buffer 101. The packets stored in the device 104 are removed when the ACK is detected and then transmitted again if no ACK is detected. A control circuit 113 opens a gate for transmission of signals when the output of a carrier sensor 111 shows an idle state. An arithmetic circuit 115 replaces the parameter Pk when no packet is transmitted or the parameter Pi of a memory circuit 114 is transmitted.
