Title: Unrequired alarm suppression method and device in wavelength multiplex communication network
Inventor: WATANABE ATSUSHI
IPC: H04L69/40
Filed: 1998-03-04
Abstract: PROBLEM TO BE SOLVED: To suppress an unrequired alarm at an optical multiple section terminating poimt and an optical channel connection point and to easily identify a fault part. SOLUTION: When optical input interruption 51 is detected, an OTM index in an optical multiple section is subtracted by one and a node 4 is informed. Thus, the wavelength multiplex number (=2) of optical signals actually received by the node 4 and the OTM index defined in the optical multiple section become equal and OTM index mismatch 55 is canceled (57). Also, by the cancellation of the OTM index mismatch 55, the alarm is not reported to OpS (58). Thus, the unrequired alarm from the optical multiple section terminating point 44 and the optical channel connection point 35 is suppressed.

Title: Scroll compressor
Inventor: SAKATA KANJI
IPC: F04C18/02
Filed: 1982-03-31
Abstract: PURPOSE:To reduce the mechanical loss of an Oldham's mechanism used in a scroll compressor, by employing such an arrangement that an annular Oldham's ring having a particular circumferential cross section has a radial width at the contact surfaces where the ring is held in contact with a frame and a turning vane smaller than the maximum radial width of the ring. CONSTITUTION:An Oldham's ring 16 is shaped in an annular form and has a particular circumferential cross section in the form of a barrel. That is, opposite portions 16a, 16b of the cross section where the ring 16 is held in contact with a frame 2 and a vane carrying disk 14 are made straight while two side portions 16c, 16d connecting the opposite ends of the contact portions 16a, 16b are shaped in an outwardly curved form. With such an arrangement, the Oldham's ring 16 is made to have a relatively small contact area where it is held in contact with the frame 2 and a turning vane 12 in comparison with a relatively large area of the section perpendicular to the circumference of the ring 16, so that it is enabled to reduce the mechanical loss of an Oldham's mechanism used in a scroll compressor.

Title: Voltage detector for switchgear
Inventor: YOSHIDA TETSUO
IPC: G01R15/06
Filed: 1995-03-13
Abstract: PURPOSE: To obtain a voltage detector for switchgear in which the secondary circuit is reduced in size while stabilizing the output voltage by providing a guard electrode, while holding microgaps, on the outer circumferential part of an electrode and then grounding the guard electrode. CONSTITUTION: A disc electrode 12 is disposed oppositely to a main circuit conductor 11 and the electrode 12 is fixed with an insulated wire 14 connected with the secondary circuit. A doughnut-like guard electrode 17 is provided around the electrode 12 through a microgap and secured to a board wall 15 by means of upper and lower securing rods 18a, 18b and thereby it is set at the ground potential. The securing rod 18a is slightly thinner than the securing rod 18b and since it is slidable freely, the rate of electric line of force being interrupted is varied according to the position of the guard electrode 17. Consequently, output voltage can be controlled by regulating the height of the guard electrode 17 while fixing the capacitance of secondary circuit. Height of the guard electrode 17 can be regulated with low voltage because it depends on the static field.

Filed: 1989-03-07
Abstract: PURPOSE:To prevent imperfect bonding and the decrease of bonding strength by arranging a high melting point metal layer which is hardly scratched by a measuring terminal, under an AL pad. CONSTITUTION:On a single crystal substrate 11, a metal Mo layer 13 and an AL layer 14 are formed via an insulating film 12, and a necessary part is left while the other part is eliminated by photoetching.

Filed: 1983-03-29
Abstract: PURPOSE:To enable high speed response and to prevent the stray of output air pressure caused by the breaking of a power source, by discharging held output air pressure from a second nozzle flapper system when the power source is interrupted. CONSTITUTION:The output air pressure from a pilot valve 16 is applied to the bellows 24 of a feedback system through a solenoid valve 28 and air pressure to a second nozzle flapper system 27 follows the output air pressure.
