Title: Dust cap of speaker
Inventor: ABE TAMOTSU
IPC: H04R9/02
Filed: 1982-02-13
Abstract: PURPOSE:To suppress the resonance of a speaker dust cap and to prevent the malformation of a diaphragm as well as the rubbing of a voice coil, by using the resin mixed with single crystal fibers of potassium titanate to the material of the speaker dust cap. CONSTITUTION:The 15% single crystal fibers of potassium titanate is mixed into polypropylene to obtain a pellet.

Title: Carrier regenerating circuit for multi-value amplitude modulation
Inventor: MATSUE HIDEAKI
IPC: H04L27/38
Filed: 1983-02-14
Abstract: PURPOSE:To implement circuit integration of the titled device by digitizing a demodulating signal and obtaining a carrier phase error signal by the digital signal processing to eliminate the need for adjustment. CONSTITUTION:A 16 orthogonal amplitude modulation (16 QAM) signal is phase- detected, the level is adjusted and inputted to an A/D converter 21. When the signal is converted into a 8-bit digital signal, the high-order 2-bit is recognized as a 4-value signal. The direction of shift from a normal signal point location is discriminated because of the production of a carrier phase error by setting the discriminating level of the high-order 3rd bit to a 4-value signal point. The amount of phase shift is grasped by the low-order 5 bits from the high-order 4th bit to the 8th bit. Thus, the carrier phase error is obtained by using the low- order 6 bit to detect the amount of interference between codes. The amount of control in response to the error is read from an ROM and converted into an analog value to control a VCO18.
