Abstract: PURPOSE:To attain quick detection of a faulty secondary station by applying synchronization check for an output data by a 2nd synchronizing check section in a bypass mode, and applying self-diagnosis. CONSTITUTION:The secondary station has two modes, in-operation and in-bypass modes, and the secondary station fetches a data from an input side transmission line during the normal operation, a synchronization check section 12 checks the sychronization, a data processing section 13 fetches it when the data is addressed to its own address, then the section 12 sends it to a terminal equipment and when the data is not addressed to itself, the section 12 sends it to an output side transmission line. In the bypass mode, the input and output sides of a transmission line 20 are connected directly and the output of a data processing section 13 is sent to a synchronizing check section 14. thus, the self-diagnosis at each secondary station is attained, and if a fault takes place, the mode stays in the bypass mode as it is, and prohibiting the data from restoring to the operation mode to stop the faulty secondary station autonomously, thereby separating the station from the system.

Abstract: PURPOSE: To efficiently execute degassing and filtering of a liquid by providing the apparatus with a means for cleaning a filter by using a circulating stream which is taken out of a main filter and is subdivided into a liquid stream continuously passing a main filter. CONSTITUTION: The coating liquid for photographic films enters a degassing vessel 4 via a connecting pipe 3 from a feed vessel 2 and is degassed by ultrasonic waves. The liquid emerging from the degassing vessel 4 enters the inflow chamber of a main filter unit 13 and is filtered.

Abstract: PURPOSE:To prevent contamination by resin chips in the interior of a disk- driving device and a disk-containing case by a method wherein a plate member is provided to a part of a shutter member, to which a shutter opener of the disk-driving device touches, so that the plate member intersects with the face of the shutter, and the surface of a part of the plate member that touches on the shutter opener of the disk-driving device is made in curved shape. CONSTITUTION:When recording or playback is made with a disk-containing case inserted into a recording and playback device for the disk, a shutter member 8 of the disk-containing case is opened by operation of a shutter opener of the recording and playback device for the disk, and an opening 8c of the shutter member 8 is made to agree with a slit-like opening 6 that is provided for insertion of a recording head. As the shutter opener of the recording and playback device for the disk touches only on curved, extended plate member 12 of the shutter member 8 when the opening action is made, the shutter opener made of resin is not scraped off. Therefore there is no possibility of scattering of resin chips inside the recording and playback device for the disk and intrusion of same into the inside of the disk-containing case.

Abstract: PROBLEM TO BE SOLVED: To provide a conductive belt having a limited variation in resisistame over time and stable even to an environmental change by adjusting volume specific resistance in a specific value range by blending a conductive filler, and using rubber to satisfy a specific formula. SOLUTION: A conductive belt is composed of rubber whose volume specific resistance is adjusted to 10<6> to 10<13> Ω.cm by blending a conductive filler, and this rubber satisfies (0.5<=logR0 -logR<=3).

Title: Temperature correcting device for camera
Inventor: KUNISHIGE KEIJI
IPC: G01K13/00
Filed: 1988-12-27
Abstract: PURPOSE:To enable high-precision, stable film exposure by writing environmental temperature data which is measured by a temperature measuring means in a storage means at the timing of a camera sequence where the influence of a heat generation source disappears. CONSTITUTION:The environmental temperature data which is measured by the temperature measuring means 1 is stored in the storage means 3 before the power circuit block in an IC operates, and external data 5 is corrected based upon the environmental temperature data. Camera driving is controlled according to the arithmetic of the temperature correction arithmetic. In this case, the environmental temperature data is stored in the storage means 3 at the timing of the camera sequence where the IC temperature becomes nearly equal to the environmental temperature after IC heat generation. The environmental temperature data which is stored in the storage means 3 is therefore updated at the time when the IC temperature becomes nearly equal to the environmental temperature. Consequently, variation in the environmental temperature can be followed up sufficiently.

Abstract: PURPOSE:To detect promptly if a double-heat transfer tube is damaged, identifying said double-heat transfer tube at the same time and hence enhance reliability and safety by laying out fluid plenum 7 detect the damage of said heat transfer tube for each tube. CONSTITUTION:Helium plenum 43 is provided for every double-heat transfer tube 1. Therefore, it is possible to identify the outer pipe 21 of a double-heat transfer tube 1 by discriminating which helium plenum 43 has lowered its pressure when the outer pipe 21 of the double heat transfer tube 1 is damaged during operation. Furthermore, the clearance between the inner surface of the outer pipe 21 of the double-heat transfer tube land the outer surface of the inner tube is filled with helium whose pressure is identical to plenum 43 or the plenum is flowing in the clearance. As helium flows out from this clearance to the side of sodium, the pressure of helium drops. It is, therefore, possible to detect the damage of the outer pipe of the double-heat transfer tube 1 in an early stage.
