Title: Method and and equipment for simultaneous transmission reception communication
Inventor: KUDO YASUSHI
IPC: H04J3/00
Filed: 1993-03-24
Abstract: PURPOSE:To provide a simultaneous transmission reception communication method and to realize a method as the simultaneous transmission reception communication equipment at a low cost in which the increase in a speech frequency band due to time axis compression of a voice signal is not caused and the deterioration in voice quality is sufficiently suppressed. CONSTITUTION:A voice signal is multiplexed by superimposing an original spectrum signal (a) obtained through a comb-line filter 11 and an inverted spectrum signal (b) obtained by inverting the frequency arrangement of the signal (a) at a spectrum inversion circuit 13 with each other thereby interpolating missing of a reception signal for a transmission period. The comb-line filter 11 acts as forming alternately its pass band and its block band at a predetermined frequency interval DELTAf and like forming a frequency space between the pass bands. Then the signals are superimposed by utilizing the space period to implement the simultaneous transmission reception communication through a single transmission system without causing the deterioration in sound quality.

Abstract: PROBLEM TO BE SOLVED: To make an excessive current not to flow through an MR element by connecting a varistor to the MR element and making the current flow through the varistor in such a case that a high voltage is applied to the element. SOLUTION: An MR element 12 is arranged between a lower layer shield 10 and an upper layer shield 11. An under coating layer 13 is made of a prescribed insulating material to achieve the insulation between a substrate 2 and a varistor 14. Then, the varistor 14 is formed on the under coating layer 13.

Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To prevent shake caused by angle shift without performing mechanical adjustment by driving a correcting lens by amount arithmetically calculated and corrected based on at least one measured value of angle shift on the detecting sensor of a shake amount detecting means and the correcting lens of a shake correcting optical system.

Thus, the respective angle shifts of the respective correcting lenses are obtained by measurement, these data are stored in a camera, so that accurate shake correction in which the angle shift is absorbed by performing arithmetic calculation obtained by adding the angle shift can be performed in the case of arithmetically calculating the driving amount of the respective correcting lenses.
