Title: Uniformly heating device for substrate
Inventor: ROBAATO FURANKU EDOGAATON
IPC: C23C16/50
Filed: 1983-07-12
Abstract: Apparatus for developing a substantially uniform temperature distribution across the entire transverse width of a relatively thin, relatively large area substrate onto which a plurality of amorphous semiconductor layers will be deposited in a glow discharge deposition chamber. The apparatus includes a plurality of spaced heating elements, the filaments of which are suspended above and angled relative to the plane of the substrate so as to direct radiation onto that portion of the substrate which loses heat at the greatest rate with at least the same intensity as, and preferably greater intensity than, radiation is directed onto those portions of the substrate which lose heat at lesser rates. By establishing the greatest intensity of radiation adjacent that portion of the substrate which most readily loses heat, a uniform distribution of temperature across the transverse width of the substrate may be achieved.

Title: Noise reduction circuit
Inventor: OOTAKI KIYOSHI
IPC: H04B1/16
Filed: 1983-07-13
Abstract: PURPOSE:To reduce noise while keeping the feeling of stereo by cutting off the high frequency component of a sub-signal when an output voltage is small and giving the feeling of spred by means of a delay device. CONSTITUTION:A main signal (L+R) and a sub-signal (L-R) are obtained by a matrix circuit 4 from an Lch output 2 and an Rch output 3 obtained from a stereo demodulator 1, the envelope of this sub-signal is detected by a detector 7 and leading edge of the sub-signal is obtained by differentiating the output of the detector 7 by a differentiating device 13. When the leading of the sub- signal is short, a VCF6 is controlled so that the cut-off frequency fc of the VCF6 is high and the fc is lowered in other cases. That is, when the noise component is much, since the leading of the sub-signal is comparatively slow, the cut-off frequency fc is lowered, a high frequency component of the sub-signal is not outputted from the VCF6, and when the noise component is less, the leading of the sub-signal is sharpened, the fc is increased, the high frequency component is outputted to provide the feeling of direction and fixed position.
