Title: Atm svc duplex system
Inventor: TERASAKI YUTAKA
IPC: H04L45/586
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To improve the service reliability of an ATM(asynchronous transfer mode) network using an ATM exchange, etc., by continuing with no interrupt the supply of the ATM main signal information via the SVC(switching virtual connection) even when a working system is switched to a standby system. SOLUTION: A working switch part 2a and a standby switch part 2b share the same routing set and also a working storage medium 6a and a standby storage medium 6b share the SVC information. If the switching is carried out by some reason between the working and standby systems under such conditions, the SVC exists or disappears between the ATM subscribers 10 and 11 since the first routing set of the part 2b is already shared with that of the part 2a by a call processing control function 4b. Thereby the transmission service of the ATM information is continuously supplied with no interrupt via the SVC.

Title: Method for applying viscous liquid
Inventor: UCHINONO YOSHIYUKI
IPC: B05D1/26
Filed: 1989-12-20
Abstract: PURPOSE:To suppress cobwebbing and to prevent the occurrence of defects by applying a viscous liq. from a nozzle to a material to be coated, cooling the nozzle side and warming the material side. CONSTITUTION:A nozzle 1 is lowered, an adhesive 2 is applied to a material 3 to be coated and the nozzle 1 is raised.

IPC: F22B35/00
Filed: 1987-12-25
Abstract: PURPOSE:To enable compaction and facilitate scale adhesion preventing treatment by controlling a feed-water pump, feeding the water of an open type feed water tank to a steam generator and opening a drain valve using a ball valve at the time of stopping operation. CONSTITUTION:The water which is stored in an open type feed water tank 10 is fed in a steam generator 2 by the use of a feed water pump 9 and the operation of the feed water pump 2 is stopped when a water level is detected by a water level sensor 6. When steam is produced and a lowering water level is detected by a water level sensor 7, the feed water tank 10 may have almost the same water level as the steam generator 2 without applying steam pressure in the open type feed water tank 2 because pressurized water is fed and can compactly be housed while the feed water pump 9 is driven and water is supplied. Further, with a drain valve 12 using a ball valve opened, hot water and peeled-off and settled scales 25 are drained in a stroke with the steam pressure before operation by an operating stop signal. Therefore, water feed and drain is performed for a short time and the scales can be prevented from being produced in the steam generator.

Title: Constant-voltage generating circuit
Inventor: NAKABAYASHI TAKASHI
IPC: G05F3/16
Filed: 1988-12-28
Abstract: PURPOSE:To always generate a stable voltage to a power supply voltage by compensating a fluctuation caused by a variation of an ambient temperature of a forward voltage of a diode by a fluctuation of a gate - source voltage of a second field effect transistor (FET). CONSTITUTION:A source follower is constituted by connecting in series resistances R4, R5 and a diode D between the reference potential (ground) and a negative power source Vss, and connecting in series a second FET2 which is greatly influenced by a temperature variation and a third FET3 which is scarcely influenced by a temperature variation, and the anode potential of the diode D is outputted to this source through a gate of a second FET2. A fluctuation caused by a variation of an ambient temperature of a forward voltage of the diode D is compensated by a fact that a gate - source voltage of a second FET2 is fluctuated in accordance with a drain - source current of a roughly prescribed value of a third FET3. In such a way, a stable voltage is always generated to a power supply voltage without being influenced by a temperature variation of the periphery, and also, by following up a fluctuation of the power supply voltage.
