Title: Cathode-ray tube for light source
Inventor: TAKADA JIYUNICHI
IPC: H01J63/06
Filed: 1982-05-18
Abstract: PURPOSE:To obtain a cathode-ray tube for a light source, in which the relative shift between the center of a fluorescent screen and the center of emission can be suppressed, by locating the center of the beam-passing hole of a cathode- current controlling electrode apart from the tube axis toward a specified direction. CONSTITUTION:An electron-beam passing hole 11a provided in the first grid 11, is located apart from the axial center 10 of a tube body toward the opposite side of a high-voltage supply lead wire 8. In such a constitution, although the orbit of an electron beam 7 is apart from the tube axis 10 at the point when the beam 7 is discharged from a cathode 1, the beam 7 is curved by asymmetric electric field formed between the first grid 11 and the high-voltage supply lead wire 8. As a result, the initial shift of the beam 7 from the tube axis 10 is set off by the shift toward the opposite side which is caused by the asymmetric electric field, and the center of a fluorescent screen and the center of emission can be made to coincide to one another.

Title: Digital filter circuit
Inventor: TOUJIYOU TAKAO
IPC: H03H17/04
Filed: 1982-05-21
Abstract: PURPOSE:To set the primary delay constant at 0-infinity , by using a digital filter. CONSTITUTION:A subtractor 1 performs a subtraction between the i-th input Xi and Yi-1 supplied from a storage device 4. A constant multiplier 2 performs (alpha) multiplication of the output (Xi-Yi-1) of the subtractor 1 by the set numerical value. An adder 3 performs an addition of the output alpha(Xi-Yi-1) of the multiplier 2 and the output Yi-1 of the device 4 and delivers Yi-1+alpha(Xi-Yi-1). The device 4 stores the output of the adder 3 and then delivers this output at the next operation. This output means that an operation Yi=Yi-1+alpha(Xi-Yi-1) is carried out for an output signal X to obtain a filter effect. Therefore, it is possible to set the primary delay time constant at 0-infinity  by varying the filter coefficient alpha in a range 0-1.

Title: Fm demodulating device
Inventor: TSUJI MASAKI
IPC: G11B20/06
Filed: 1986-04-15
Abstract: PURPOSE:To compensate signal lack due to the clipping processing of a clipping means by extending the amplitude level of a changing part from the black level to the white level of a demodulated output. CONSTITUTION:A luminance signal S1 is demodulated by an FM demodulating circuit 11. A noise N is mounted on a leading part from the black level to the white level of an output signal S2 of an LPF 12. The noise is removed by passing the signal S2 through a white clipping circuit 13. The amplitude level of the leading part of a signal S3 is extended by an extending circuit 14. Consequently, a signal component lacked by the clipping processing can be compensated. Thereby, a luminance signal S5 having excellent waveform characteristics and removing the noise N can be obtained by the deemphasis processing or the like of the signal S4.
