Title: Method and device for suppressing howling
Inventor: UCHIYAMA TOMOAKI
IPC: H04R3/02
Filed: 1998-09-17
Abstract: PROBLEM TO BE SOLVED: To effectively suppress howling even in the case of generating a change over aging in a system or processing by an adaptive echo canceler. SOLUTION: In a bidirectional communication system arranging respective microphones 2a, 2b and speakers 1a, 1b in respective rooms A, B for transmitting/receiving sound signals through communication lines T, each echo cancler 6a (6b) estimates a creep component from the speaker 1a (1b) arranged on the same side to the microphone 2a (2b), removes the estimated creep component from an input signal inputted from the microphone 2a (2b) to obtain an error signal and updates a coefficient for estimation based on the error signal. Each variable notch filter 7a (7b) monitors the unstable area in the spectrum of the error signal, and when the unstable area is increased, executes filtering so as to suppress its frequency component.

Filed: 1984-12-18
Abstract: PURPOSE:To diminish landing misregistration due to thermal expansion of a frame supporter by fixing the frame supporter to the extended part formed at the end face of a mask frame side wall. CONSTITUTION:The body structure 21 of a shadow mask is composed of extended part 232 attached to the center of both long and short sides of side walls 231 of a mask frame 23 and extending in the direction opposite to shadow mask 22, a frame supporter 24, hooking hole part 241 near the other end parts, etc., with the hooking hole part 241 hooked to a panel pin 25.

Title: Interruption control circuit
Inventor: MIYAZONO TAKASHI
IPC: G06F13/24
Filed: 1988-10-21
Abstract: PURPOSE:To prevent interruption of the operation of a micro-processor by arbitrarily controlling the permission/nonpermission to an interruption requesting signal from a peripheral circuit of the microprocessor. CONSTITUTION:When a reset outputting signal from an address decode circuit 20 to a signal line 2 changes from '1' to '0', the contact 30-1 of a relay 30 for latching is connected to A side and an interruption requesting signal from a peripheral circuit on a signal line 5 is sent to a signal line 6 as it is. On the other hand, when a set outputting signal sent to a signal line 4 from the circuit 20 changes from '1' to '0', the contact 30-1 is connected to B side and the interruption requesting signal on the signal line 5 is ignored. In such state, the permission/nonpermission to the interruption is controlled by controlling the rest signal on a signal line 1 or 8 in accordance with a program. Therefore, control of an interruption request can be programmed arbitrarily and the interruption of the operation of a microprocessor can be eliminated.

Abstract: PURPOSE:To give a function to reduce the misregistration of images in a digital subtruction angiography(DSA) examination, to an image intensifier (I. I.) device which has a function to cut off the earth magnetism automatically. CONSTITUTION:When a normal X-ray fluorescent image is obtained, a magnetic sensor 23 detects the earth magnetism input from an input surface substrate 21, and a feed current controller 24 controls a current fed to a correction coil 22 depending on the detecting result, so as to cut off automatically the earth magnetism input from the input surface substarte 21 by the magnetism generated by the correction coil 22. When a DSA examination is carried out, an external signal GS is given to a ratch circuit 25, and thereby, a current given to the correction coil 22 immediately before the external signal GS is input is operated to be given to the correction coil 22 constantly, in the ratch circuit 25. Since a mask image and a live image are photographed in the condition that the magnetic field from the correction coil 22 is constant, the misregistration of the images is reduced.
Patent JP-H09120448-A (JP)
Title: Image processor and method therefor
Inventor: KATO KOICHI
IPC: H04N1/60
Filed: 1989-10-06
Abstract: PROBLEM TO BE SOLVED: To easily perform the desired image processing by designating an image processing instruction in the sensitive vocabularies. SOLUTION: When a register mode is selected by register key, a liquid crystal screen is changed to the display for selection of a register number. A user pushes the #1 touch key for his desired number 1 to be registered. If the user feels 'warm' from a certain red group color tone, he puts the corresponding original on an original board and pushes a start key. Thus an image reading part 1 starts its reading operation. The read image data undergo the shading correction and the logarithm conversion and are sent to a color modulation part 4. If the color adjustment is needed to an input image to make the user feel 'warm', the 'warm' key is pushed. Then a copying operation is carried out with color adjustment when the user pushes the strength keys to move a cursor and to select the adjustment strength and then pushes an end key.
