Title: Method for calculating sound field characteristic
Inventor: MIYATA HIROYUKI
IPC: G10K15/00
Filed: 1990-01-26
Abstract: PURPOSE:To highly accurately evaluate various kinds (types) of sound fields by multiplying the square h<2>(t) of an impulse response from a sound source position up to a listener's position by a function W(t) for time weight and calculating the intensity modulated transmission function mW(F) of the sound field based upon a specific equation. CONSTITUTION:In order to make great account of the transient characteristics of a time area including a direct sound and an initial reflected sound obtained immediately after the arrival of the direct sound, the square h<2>(t) of an impulse response from the sound source position up to the listener's position is multiplied by the function for time weight, i.e. a function (time window)W(t) to be attenuated with the lapse of time, and the intensity modulated transmission function mW(F) indicated by the equation is found out by using the multiplied value.

Title: Original platen driving device of copying machine
Inventor: TAMURA TAKASHI
IPC: G03B27/50
Filed: 1979-02-21
Abstract: PURPOSE: To prevent the failure of copying by providing a means of detecting the deviation of the original platen.  
     CONSTITUTION: The 1st, 2nd switches S 1 , S 2  which are actuated are provided at the lower end face 7d of a drive member 7 which reciprocates an original platen 9 and the lower end face 12b of a collision plate 12. When the drive member 7 and original platen 9 engage and return to the start position from the right direction, the contacts of the 2nd switch S 2  are changed over from Y to X and the 1st switch S 1  is turned OFF. As a result of this, the 2nd switch S 2  changes over to the Y contact if the original platen 9 is disengaged from the drive member 7 at the time of starting. The disengagement of the original platen 7 is then displayed through light emission and the drive motor does not run despite turning ON of the copy switch. Hence, when the original platen 9 disengages from the drive member 7 owing to the action of abnormal force, the copying machine does not operate and the failure of copying is prevented.
