Title: Distance detecting method and device utilizing propagation characteristics of foghorn sound
Inventor: YAMADA KAZUNARI
IPC: G10L25/24
Filed: 1990-05-18
Abstract: PURPOSE:To obtain the horizontal distance from the sound ray difference, the geometric structure of the sound ray concerning the propagating route, and the height of the sound receiving point by receiving the direct sound wave of the foghorn sound and the sound wave reflected by the sea surface at two points, measuring the delay time between both sound waves by the cepstrum method, and obtaining the sound ray difference of both sound waves at both sound wave receiving points from the production of the delay time and the sound velocity value in the atmosphere. CONSTITUTION:The foghorn sound wave of an approaching ship is received by the concerned ship in such a manner as the direct sound wave and the sound wave reflected by the sea surface may be superposed. Sound receivers 1, 2 are mounted at two points of a mast or the like whose heights of direct direction are different, the foghorn sound wave is received at the respective points, and signal processing is implemented by the cepstrum method concerning the respective received signals at the sound receiving points, and the delay time of the reflective sound wave relative to that of the direct sound wave is obtained. Then, from the production of this delay time and the velocity value of the sound propagating in the atmosphere which is separately obtained on the real time basis, the sound ray difference is obtained by the difference in the propagating route of the direct and the reflected sound waves. Successively, the horizontal distance to the approaching ship and the height of the foghorn sound source can be calculated from the geometrical structure of the sound ray concerning the propagating route of the foghorn sound, the sound ray difference and the height of the sound wave receiving point.

Title: Spectacle frame
Inventor: OOTSUKA SHIGEO
IPC: G02C5/12
Filed: 1978-10-16
Abstract: PURPOSE: To obtain the comfortable spectacles which prevents slip-down of the spectacles and whose pads do not bite into the nose by providing the nose seating pads built in with elastic materials to the lens frame of the spectacles and constituting the same movably in follow up to the expansion or contraction of the skin.  
     CONSTITUTION: Along with the change in the face expression, skin motion occurs and nose seating pads 6 follow up this sking expansion or contraction against elastic materials S. The moving loci of the nose seating pads 6 are defined by the pins 7 fitted in guide oblong holes 5. Since this perfectly eliminates the floating phenomenon of the pads 6, the slip-down of the spectacles and the bite of the pads 6 into the sking occurring in the slip-down are surely prevented. The nose seating pads are able to accurately follow up and move in the expansion or contract direction of the skin within the range of the guide oblong holes and the slip-down of the spectacles owing to the expansion or contraction of the nose skin is perfectly eliminated, whereby the spectacles may be held always in the optimum position.

Title: Method for controlling alloying degree of galvanized steel sheet
Inventor: KAWAHARA MASAHIRO
IPC: C23C2/28
Filed: 1993-05-28
Abstract: PURPOSE:To reduce the variation in alloying degree of a galvanized steel sheet at the transition stage by calculating the difference of heating system and further the difference of the progressing degree of the alloying and deciding a compensating input heat quantity, at the time of controlling the compensation of delay at a low- response main operational terminal by a high-response auxiliary operational terminal in galvannealing treatment of gas heating assisting induction heating. CONSTITUTION:A strip 8 after galvanizing is galvannealed by the induction heating (IH) 2 and the gas heating (GH) 3 having the operational terminal, respectively. In the case of changing a coil, the setting temp. of GH 3 is changed, but there is delay untill reaching to the aimed temp., so that the setting voltage in IH 2 is changed so as to compensate this shortage to the input heat quantity. In an input heat parameter for deciding the setting temp. of GH 3, the alloying degree is inputted, but the variation in the alloying degree is non-linear to the input heat quantity. Therefore, since the difference of the operational terminals, i.e., the difference of the input heating system corresponds to the variation in the alloying degree by using arithmetic expressions I-III, the operational quantities at the operational terminals in GH 3 and IH 2 are decided.
