Title: Active type noise controller
Inventor: ISHIKAWA YASUTAKE
IPC: G10K11/16
Filed: 1991-07-19
Abstract: PURPOSE:To prevent an abnormal sound due to the divergence of the control system of the active type noise controller from being generated. CONSTITUTION:An evaluation function J is calculated (step S4) from microphone inputs e1-e3 when the filter coefficient Wmi(n+1) of an adaptive filter is updated and the gradient deltaJ/ W of the evaluation function J to the filter coefficient is calculated (step S5). Then it is decided (step S6) whether or not the evaluation function J is larger than an evaluation function threshold value J0 and when J>J0 is obtained, monitor timer T is set (steps S9-S11) and the frequency N of variation in the sign of the gradient deltaJ/ W is counted (step S12) until the monitor timer T enters a time-up state. When the frequency N of variation exceeds a set value NS, the divergent state due to a model spatial transfer function and an actual spatial transfer function is judged to cut off the supply of a driving signal to a loudspeaker.

Title: Inspecting method for magnetic disk
Inventor: SASAKI TOSHIHARU
IPC: G11B20/18
Filed: 1980-12-19
Abstract: PURPOSE:To inspect a magnetic defect with precision by obtaining an amplified signal having constant amplitude without reference to whether a magnetic disk is set normally or upside down, by controlling a gain for the readout amplification of an inspection signal written on the magnetic disk. CONSTITUTION:For a measurement of the absolute value of the amplitude of an inspection signal, a switch 1 is changed over to the side of an attenuator 2 and a fixed-gain circuit 3 to fix a gain covering more than one track. For inspecting relative variation in amplitude, on the other hand, the switch 1 is changed over to the side of a variable gain circuit 5 to vary the gain so that the amplitude of a signal read in the starting short time of the readout period of each track is within prescribed range permitted by a trailing circuit and the varied gain is kept as it is in the remaining period. Further, for the inspection of whether any part is unerased or not and its intensity, the inspection signal is erased by a DC erasure signal and the gain before the erasure is held as it is without changing over the switch, thus performing reading operation.

IPC: G06F3/041
Filed: 1998-06-26
Abstract: PROBLEM TO BE SOLVED: To prevent a malfunction of a touch panel provided with a polarizing plate caused by a temperature change and to facilitate the assembly of that touch panel by providing the polarizing plate placed on the outer surface of a transparent movable substrate without being bonded onto that outer surface by a transparent adhesive agent.

Title: Electromagnetic stirrer
Inventor: HIRAYAMA FUJIO
IPC: B22D11/115
Filed: 1983-09-30
Abstract: PURPOSE:To obtain a casting body having a good surface by making the distance between the iron cores of an electromagnetic stirrers disposed on the outside of the side wall of a casting mold and the molten steel in the mold gradually larger from the upstream side to the downstream side of the molten metal thereby weakening stirring in the part where waving arises and stirring thoroughly the other part. CONSTITUTION:When electric current is passe to a coil 15, stirring force is generated by a moving magnetic field and molten steel 16 flows but as the distance between iron cores 14 and the molten steel 16 increases gradually from the upstream side of the molten steel toward the downstream side and therefore the magnetic flux density attenuates exponential-functionally and the stirring force in the corner parts 18 where the molten steel 16 changes the direction of flow as shown by the lengths of arrows 17 is made smaller than the stirring force in other places. The flow rate in said parts decreases and therefore waving does not arise. The stirring force is made optionally adjustable by adding a mechanism to vary the distance between the iron cores 14 and the mold to obtain a higher effect.
