Title: Sound field controller, its method, and program recording medium for the controller
Inventor: MIYOSHI MASATO
IPC: H03H17/00
Filed: 1998-03-24
Abstract: PROBLEM TO BE SOLVED: To provide a sound field controller which is able to prevent the occurrence of ringing phenomena or the breakage of a loudspeaker by attenuating the signals, having a frequency affected by an unstable zero point and, in addition, can achieve desired characteristics for signals having other frequencies. SOLUTION: Frequency ω0 affected by an unstable zero point is obtained by using the error signal e(n) between a reference signal d(n) from a reference signal generating filter 3 and a replica c(n) from an adaptive filter 4 and the reference signal d(n), and the frequency ω0 is set as the passband of a filter 7. Then the signal obtained by passing a pseudo-noise through the filter 7 is inputted to the adaptive filter 4, by adding the signal to an observed signal y(n) at a listening point, and the filter 4 is controlled so as to minimize the power of the error signal 3(n). The resulting filter coefficient is set at a convolver 1, and original sounds s(n) are supplied to a loudspeaker and the reference signal generating filter 3 through the convolver 1.

Title: Filament supply method for automatic spool winder and device therefor
Inventor: NARUMI IWAMI
IPC: B65H49/10
Filed: 1991-03-15
Abstract: PURPOSE:To improve work efficiency and enable the unmanned operation of a device by disposing numerous bobbins with the axes thereof directed to thread paths, and swelling filament outward by rewinding centrifugal force generated by the specified pull-out speed, as well as linking the terminuses with the starting ends of the wound filament successively to pull it out. CONSTITUTION:The starting end, where filament 12 is pulled out first, of a bobbin 13 is wound around a pulley 5 through a thread guide 6, and the terminus is bound to the starting end of the filament wound around a second bobbin adjacent to the bobbin 13 or connected by a binding part 14. The filament terminus of the second bobbin is further connected to the filament starting end of a third bobbin in the same way. Also in bobbins in the lower stage, connection is performed successively in the same way so that the whole filament is linked into one. In this state, an automatic spool winder is driven to rotate a motor 4 and a pulley 5 for the pull-out of the filament 12. When the specified pull-out speed is provided at this time, centrifugal force works on the filament itself so as to enable speedy rewinding with an outward swollen arc described around an axis, and thus the filament can be pulled out without rotating the bobbins themselves.

Title: Semi-conductor device
Inventor: KURATA MAMORU
IPC: H01L29/73
Filed: 1978-06-26
Abstract: PURPOSE:To reduce forward voltage drop greater than before by providing a layer in which a slight concentration difference of both p-type and n-type impurities effectively act as a one-side impurities. CONSTITUTION:When both a donor and an ecceptor with densities of ND1 and NA1 respectively are diffused from the surface of a n-type substrate having a density of NDB, they cancel each other. As a result, a low density n-type zone or a high compensation zone 22 is formed. During diffusion process, a n<+> zone (ND2) which is formed in later process is avoided, thus leaving the zone having density of NDB in the substrate between the n<+> zone and the high compensation zone 22. NA2 is a p-type diffusion zone, thus forming a p-n junction 25. In this constitution, relatively high density doner and acceptor are diffused from the surface of the semi-conductor substrate to cancel each other for obtaining the low n-type zone where electron density is higher than intrinsic semi-conductor, a band gap is smaller, and the amount of forward voltage deop is lower.
