Title: Variable power finder
Inventor: MURATA YASUNORI
IPC: G02B13/18
Filed: 1997-02-15
Abstract: PROBLEM TO BE SOLVED: To observe an excellent finder image all over the variable power range at the wide angle of view by performing variable power by moving a 2nd group on an optical axis, correcting the change of diopter caused by the variable power by means of a 1st group and satisfying a specified condition. SOLUTION: An objective lens system is constituted of the negative 1st group consisting of a negative lens whose both lens surfaces are concave, the positive 2nd group consisting of a positive lens whose both lens surfaces are convex and a positive 3rd group consisting of a positive lens whose convex surface faces to an image surface. By moving the 2nd group to an object side, the variable power is performed and the change of the diopter of a finder caused by the variable power is corrected by moving the 1st group while keeping a convex locus on the image surface side.  When it is assumed that the radii of curvature of the lens surfaces of the 3rd lens on the object side and the image surface side are R3a and R3b and a distance between the 2nd and the 3rd lenses at a wide-angle end is SAW and the focal distance of an objective lens at the wide-angle end is fW, the condition shown by expressions I and II is satisfied.

Title: Active filter circuit contaning noise canceller
Inventor: UEDA SEIICHI
IPC: H04B1/10
Filed: 1978-04-24
Abstract: PURPOSE:To cancel the noise completely by applying the output of the noise canceller to the connection between the feedback element and the CR circuit. CONSTITUTION:The output of the CR circuit comprising resistance R1 and R2 connected in series plus capacitor C1 is applied to amplifier circuit Amp, and the output is fed back to connection N2 of R1 and R1. Thus, an active filter is constituted. On the other hand, the reference voltage of reference voltage generation circuit 1 is compared with the input signal to be given to input part 2 through comparator 3 in order to detect the noise exceeding the reference voltage. Thus, the noise cancel signal is generated form gate circuit 4 to be applied to node N2. The noise pulse applied to input terminal N1 causes a time delay at node N2 via the active filter and causes another delay at output terminal N3. Accordingly, the noise part which was not erased at the rise and fall time of the noise pulse can be reduced so much as to be ignored by applying the cancel signal to node N2 where the intermediate signal delay is caused.

Title: Bond flux for arc welding
Inventor: KATOU TAKASHI
IPC: B23K35/362
Filed: 1980-04-15
Abstract: PURPOSE: To improve welding workability, by specifying the compositin of flux in using anhydrous potash glass powder as potassium source.  
     CONSTITUTION: Anhydrous potash glass powder containing, by wt., ≤10W35% K 2 O, 3W30% CaO, and 35W85% SiO 2  is added to the flux by 0.5W15wt% of the total weight of flux. Moreover, the flux is controlled so that it may contain 5W35% SiO 2 , ≤20% CaO, and ≤10% K 2 O. In this case, if the potash glass is not anhydrous one, the arc will be disturbed. The anhydrous potash glass is low in melting point, promotes the melting of other raw materials, and facilitates the mixing of objective elements. Moreover, the stability of arc can be maintained because of the low-moisture absorbing property of the glass. The lower and upper limits of K 2 O are required for the workability and generation of bead dropping, respectively. The lower and upper limits of CaO are required for improvement in the moisture absorbing property, and improvement in the melting temperature and generation of undercut, respectively. The lower and upper limits of SiO 2  are required for the moisture absorbing property, and generation of undercut, respectively. Moreover, the lower and upper limits of adding amount of glass mentioned above, are required for the workability and exfoliation of slug and the shape of bead, respectively. In addition to the above, limitation of each element contained in the flux is required for the workability.
