Title: Nozzle for producing thin metallic strip
Inventor: TSUCHIYA ATSUSHI
IPC: B22D11/06
Filed: 1985-03-14
Abstract: PURPOSE:To make uniform the thickness in the transverse direction and properties of a thin metallic strip to be produced by a liquid quick cooling method and to improve the yield thereof by projecting the tip of a nozzle only at both ends. CONSTITUTION:The tip of the nozzle for producing the thin metallic strip having >=10mm width is projected by DELTAt only at both ends. The length at both ends to be projected is adequately about DELTAw=0.5-3mm except the length (b) in the thick-walled part. The length DELTAt to be projected is preferably >=0.1mm. However, the distance between the top end face at the root of the nozzle and a cooling roll is <=0.25mm and therefore the DELTAt is preferably <=0.1mm. The satisfactory suppression of the build-up at both ends of the thin metallic film is not possible if the DELTAw is too small and the central part of the thin film builds up if the DELTAw is conversely too large. The deformation of the thin strip is suppressed and the properties thereof are made uniform by producing the thin metallic film by using such nozzle.

Title: Exposure control device of cameras
Inventor: TANIGUCHI NOBUYUKI
IPC: G03B7/16
Filed: 1978-04-28
Abstract: PURPOSE: To prevent mis-exposure occurring at the lowering of subject luminance by comparing  the aperture opening count value corresponding to the preset aperture according to photometric  values and a reference value and controlling the apearture opening.   
     CONSTITUTION: The detection value of a photometric circuit 1 at the full aperture causes the  aperture opening value corresponding to the preset aperture to be stored as a voltage in a memory circuit 7 by the arithmetic circuit 4 connecting to a full aperture value output circuit 3 and  the arithmetic circuit 6 connecting to a preset aperture value output circuit 5. The storage contents are compared with a reference voltage corresponding to full aperture in a comparator  AC 2 . When the full aperture value which becomes the storage content of the circuit 7 becomes  unreasonably large owing to leakage current, etc. as the detection output of the circuit 1 becomes  small at the lowering of subject luminance, then the contacts of a switch 9 are changed over and  not the storage content of the circuit 7 but the reference voltage is applied to the comparator AC 1 .  Hence, at the lowering of the subject luminance, the aperture opening is automatically regulated  to full aperture by the circuit 1, circuit AC 1 , aperture driving circuit 8, whereby controlling, free  from mis-exposure is accomplished.
