Title: Extruded heat-exchanger tube made of aluminum alloy
Inventor: OKI YOSHITO
IPC: B21C23/00
Filed: 1998-08-21
Abstract: PROBLEM TO BE SOLVED: To enable brazing by the use of a smaller amount of flux by providing an extruded tube which is brazed by the use of a flux containing silicon powder and has a composition consisting of specific amounts of Si and the balance Al with inevitable impurities. SOLUTION: The amount of Si contained in the extruded heat-exchanger tube is regulated to 0.4 to 1.0 wt.%. Si addition is done to prevent the diffusion of excess Si which does not contribute to the reaction of formation of a brazing filler metal with Al, from a silicon powder in a flux into the inner part of a tube material and to form all the silicon powder into brazing filler metal alloy, by which the amount of brazing filler metal alloy to be formed in a brazing stage can be increased. As a result, the amount of the flux used can be reduced and also the electric potential of the tube can be raised and the potential difference between the tube and a fin can be increased to provide corrosion resistance. By adding <=0.1 wt.% Cu, the electric potential of the tube can be raised to a further extent and corrosion resistance can be improved.  At this time, >=50 mV potential difference between the tube and the fin suffices to provide the tube with corrosion resistance over a practical period.

Abstract: PURPOSE:To improve the accuracy of A/D conversion by applying A/D conversion to an offset signal of a prescribed level of the LSB of A/D conversion added to an input signal by means of one of plural A/D converters. CONSTITUTION:An input analog signal (d) is converted into a digital signal (f) by an A/D converter 10 and then outputted. A signal (e) added with the offset signal of an m/n-level (0<=m<n, and m, n are integers) of the LSB level of the A/D converter generated at an offset generating circuit 11 to the signal (d) is converted into a digital signal (g) by another A/D converter 10.

Title: Automatic exposure quantity correction device and light measuring instrument
Inventor: TOKUDA KANJI
IPC: G03B27/73
Filed: 1988-10-05
Abstract: PURPOSE:To easily correct an automatic exposure quantity and to prevent printing processing capability from deteriorating by using one scanner for one frame selectively and operating plural scanners in order, and calculating exposure correction data. CONSTITUTION:Frames recorded on a photographic film are positioned at a light measurement position by frame feeding means 44 and 45 and light at each point in a frame at the light measurement position is measured by one of the scanners 36A - 36C to compute the exposure correction data according to the light measurement result. Thus the light measurement for one frame is completed and the photographic film is fed by one frame to measure light at each point of the next frame by next scanners 36A - 36C, thereby computing exposure correction data. Thus, exposure correction data are computed through the scanners 36A - 36C, one after another, in frame order, so the arithmetic processing is performed fast as a result corresponding to the number of the scanners. Consequently, the exposure quantity can be corrected automatically without deteriorating the processing ability of the photographic printing device of a large-sized laboratory capable of high speed printing and exposure.
