Filed: 1984-10-25
Abstract: PURPOSE:To eliminate the entry of the 2nd higher harmonic component to a base band and to detect a wave even if the frequency band of an FM signal subjected to Hilbert conversion overlaps with that of an FM signal as it is by detecting said two types of FM signals, rendering the 2nd higher harmonic component to obtain signals of the same phase and reverse one with respect to a base band component and calculating them so as to cancel the 2nd higher harmonic component.

Title: Disk reproducing device
Inventor: KAGEYAMA SHUJI
IPC: G11B7/09
Filed: 1987-09-07
Abstract: PURPOSE:To prevent the malfunction due to a flaw or a stain, etc., on a disk surface and the malfunction due to a vibration by detecting the deviation in the read position of a read means from an optimum position and changing the gain of an amplifying means in accordance with the size of an error signal corresponding to said deviation. CONSTITUTION:The gain of the amplifying means 8 is changed in accordance with the size of the error signal TE corresponding to the read position of read means 1, 2 and 3, and in case of the normal state of nonvibration, the error signal TE is minimized, and hence the gain of the amplifying means is set low so that its sensitivity is lowered. Consequently, the malfunction due to a flaw or a stain, etc., on the disk surface will never arise. And, in case of the occurrence of a vibration, the error signal TE is enlarged, and hence the gain of the amplifying means 8 is set high so that the sensitivity is promoted, thus correcting quickly the deviation in the read position due to the vibration. By this method, the deviation in a beam position due to the vibration is quickly corrected, and moreover a disk reproducing device capable of operating without the malfunction due to a flaw or a stain, etc., on a disk surface is hence obtained.

Abstract: PROBLEM TO BE SOLVED: To provide an IC inspection device which can perform flexible inspections even when the ICs perform asynchronous operations. SOLUTION: At the time of inspecting an IC 5 to be inspected for synchronous operations, an input signal generating section 20 generates an input signal based on the timing generated from a timing generating section 10 and given to the input pin of the IC 5. An output signal comparing section 30 inspects an output signal outputted from the output pin of the IC 5 in response to the input signal whether or not the output signal coincides with a prescribed expected value by comparing both signals with each other. At the time of inspecting the IC 5 for asynchronous inspections, an exclusively used inspection circuit is designed and built on a gate array as software by giving the circuit data file F4 corresponding to the inspection circuit to a programmable logic circuit 50 composed of an FPGA(field programmable gate array) element, etc.  While the IC 5 is operated, actual IC tests are performed by extracting necessary signals by means of a signal selecting section 60 and giving the extracted signal to the inspection circuit built on the logic circuit 50 while the IC 5 is operated.

Filed: 1994-09-20
Abstract: PURPOSE: To provide a composite piezoelectric speaker which is excellent in flat up to a high frequency band and with less distortion by defining the joint surface of a piezoelectric element with the resin as a cut surface. CONSTITUTION: The electric signal transmitted from a sound signal source is guided by a lead wire 6 and voltage is impressed on a piezoelectric element 3 by an electrode 5. The piezoelectric element 3 is warped in its thickness direction and a composite piezoelectric body 2 vibrates in its thickness direction. This vibtation is transmitted as sound and works as a speaker. In this case, at least the part of the joint surface with the resin of the piezoelectric element 3 is made a cut surface. When the joint surface with the resin 4 of the piezoelectric element 3 is not the cut surface, the joint with resin 4 is not strong and it looks as if the joint were performed at time of no vibration. At the time of vibtation, a clearance is generated between the piezoelectric element 3 and resin 4, and the response is not in a high frequency band, in particular. The whole surface of the joint surface of the piezoelectric element 3 is not required to be the cut surface and is allowable if the joint surface is the area keeping joining strengh.
