Title: Method for compressing video signal
Inventor: MAEZATO SHINICHI
IPC: H04N5/20
Filed: 1993-12-16
Abstract: PURPOSE:To compress the level of a video signal so that an input level (y) becomes smooth in the neighborhood of a knee point KP. CONSTITUTION:The input level (y) and the level of the knee point KP are compared. When (y)<KP, an input video signal is outputted as it is without compressing the input level (y). When (y)>=KP, level difference (y-KP) detected by a level detector 5 is converted to data which smoothly increases corresponding to the level difference by using the look up table of ROM7. When the input level (y) is over a knee curve end point KE, a maximum value is outputted from ROM7. Then, an adder 10 adds a value obtained by multiplying the level difference (y-KP) by (k) times with a multiplier 8, a value obtained by multiplying the output value of ROM7 by (1-k) times with a multiplier 9 and the knee point KP.

Title: Fm demodulation circuit
Inventor: SOU YOUCHIYOU
IPC: H04N5/922
Filed: 1987-12-15
Abstract: PURPOSE:To realize FM one side band demodulation with no group delay caused therein within a required FM band by adopting the transversal equalizer+double limiter constitution so as to prevent inversion while applying FM equalization. CONSTITUTION:An equalizer circuit 8 consists of delay circuits 11, 12, adder circuits 9, 16, attenuators 13, 14, and a subtraction circuit 15. The delay is made constant in all frequency bands in the equalizer circuit 8 and FM equalization is applied without group delay. Then a high frequency component (k) extracted by the subtraction circuit 15 (cos equalizer) and passing through the 1st limiter circuit 3 and a low frequency component l extracted by the adder circuit 16 (-cos equalizer) and an LPF 5 are summed by an adder circuit 6, and the output signal (m) being the result of addition is given to the 2nd limiter circuit 7 to obtain an FM demodulation signal (n) with frequency equalization without any group delay. Thus, the group delay distortion in a required FM band is decreased.

Abstract: PURPOSE:To reproduce or record/reproduce both an NTSC signal and a high quality television signal by one optical disk device by digitizing first, second signals, and recording/reproducing digital information band-compressed up to a predetermined bit rate at a predetermined rotating speed or a predetermined linear speed. CONSTITUTION:Information recorded on an optical disk 1 is sent to a read digital demodulator 4 via optical systems 2, 3. In this case, digital information digitized from a first signal and band-compressed up to a predetermined bit rate A1 is reproduced or recorded/reproduced at a predetermined rotating speed K or a predetermined linear speed V, and digital information digitized from a second signal and band-compressed to a predetermined bit rate A2 is reproduced or recorded/reproduced at a rotating speed of about K X A2/A1 or at a linear speed of about VX A2/A1. Thus, a narrow band signal such as an NTSC signal, a wide band signal such as a high quality television signal can be reproduced or recorded/reproduced by one optical disk device.

Filed: 1990-11-20
Abstract: PURPOSE:To ensure the proper detection of an abnormality in a temperature information detection means by making a comparison between temperature information at both high and low temperature sides obtainable from a sensitivity selector means. CONSTITUTION:The output of a temperature detection thermister 16 in a heating chamber is sent to a temperature information detection means 17. The output of the means 17 is selected between high and low temperature sides via a sensitivity selector means 18. A control section 19 controls the means 17 and 18, and the first, second and third switching means 11, 13 and 15. Furthermore, a comparison is made between low temperature side voltage V1 and high temperature side voltage V2 supplied to the input section P1 of the control section 19 at a period T synchronized with a power supply frequency. When V1 is lower than V2, the detection means 17 is judged to be normal. When V1 is equal to or higher than V2, the means 17 is judged to be abnormal.

Title: Information recording medium and information detector
Inventor: MORITA OSAMI
IPC: G11B11/16
Filed: 1997-11-20
Abstract: PROBLEM TO BE SOLVED: To provide a read-only information recording medium of a high recording density, an information recording medium which allows recording and reproducing at the high recording density and an information detector which reads out such information. SOLUTION: A sensor 2 consisting of a resistor is mounted on a slider 3 floating on a disk 2 and produces output in correspondence to the projecting parts 4 formed on the disk 1. The sensor 2 is so arranged as to scan the top of the projecting parts 4 of the disk 1 slightly apart therefrom. If the disk 1 is assumed to rotate in the direction shown by an arrow R, the sensor 2 increases the release of heat energy at the front ends (a) of the projecting parts 4. The lowering of the temp. and the decreasing of the resistance value as well as the degrading of the output are resulted. The temp. remains constant while the heat applied on the resistor and heat radiation maintain equilibrium. The heat radiation decreases at the rear end (b) of the projecting parts 4.  The elevating of the temp., the increasing of the resistance value as well as the increasing of the sensor output are then resulted. The projecting parts 4 formed in correspondence to the information on the disk 1 are detected by this mechanism.
