Title: Device for controlling automatically polarizer
Inventor: NAGAO NOBUYA
IPC: H01Q21/24
Filed: 1985-09-30
Abstract: PURPOSE:To set automatically the direction of a polarizer in the best direction by preparing a control signal generator managing an AGC voltage so as to control the oscillating frequency of a voltage controlled oscillator in response to the level of an AGC voltage. CONSTITUTION:A control signal generator 26 controls charge/discharge of a low-pass filter 27 in response to an automatic gain control voltage V-AGC to be inputted. A control voltage V-CON to be fed to a control terminal of the voltage controlled oscillator 28 is obtained from the low-pass filter 27. When the control voltage V-CON is increased, the frequency of the voltage controlled oscillator 28 gets higher and when the control voltage V-CON is lowered, the frequency is decreased. Further, a polarizer control motor receiving its waveform shaping output is driven counter clockwise when the pulse width is small and driven clockwise when the pulse width is large. Thus, the polarizer is controlled to be always at the best position.

This signal is divided into data of four frequency regions -fs - fs/2, -fs/2 - 0, 0 - fs/2, fs/2 - fs and the respective data are stored in spectrum line buffers 5A, 5B, 5C, 5D. The signal intensities of signals on alternates ones present at the equivalent positions of respective blocks are compared and the outputs of spectrum line buffers 7A, 7B storing signals larger in signal intensity are synthesized. The spectrum output thereof is displayed while frequency is folded but a noise level is almost held to the original one.

Title: Cooking heater and its manufacturing method
Inventor: TANIOKA KATSUYA
IPC: F24C14/00
Filed: 1990-08-17
Abstract: PURPOSE:To easily remove fouls attached on the inner wall of a compartment by laminating a fluororesin film on an inner plate. CONSTITUTION:An inner pate 8 made of aluminized steel plate is attached on the inner side wall of an inner box 2. A transparent, non--adhesive and non-combustible fluororesin film 9 is attached on the inner face of the inner plate 8. Therefore, if oils, etc., attach on the surface of the inner plate 8, they can be easily wiped off, and also it can be prevented that the heat radiated from an upper heater 6 and a lower heater 7 is absorbed and the thermal efficiency drops, causing the cooking time period to be extended. And, as the fluororesin film 9 has a limit in thermal durability, the heater is used while the temperature is controlled by an over-heating preventive device 10. To attach the fluororesin film 9 on the inner plate 8, the tubular fluorine resin film 9 is put over the rectangular inner plate 8 and thermally shrinked so that the film 9 is attached tight on the front and back faces of the inner plate 8.

Title: Magneto-optical disk
Inventor: HASHIMOTO YASUNOBU
IPC: G11B11/10
Filed: 1989-08-25
Abstract: PURPOSE:To improve writing sensitivity while maintaining reading stability by providing a layer having higher thermal conductivity than that of a protective film in a manner that the thickness of the layer gradually decreases from the most inner circumference edge of a recording area in the disk to a specified radius range. CONSTITUTION:On a glass substrate 1, there are formed a base protective film 2 and recording film 3, and then a high thermal conductive layer 5 comprising Al is formed to cover from the most inner part R1 of the recording area 10 to the position of radius r. The layer 5 is formed by sputtering Al in a manner that the thickness of the layer decreases from the most inner circumference R1 to zero at the position where the distance from R1 is 2/3 of the distance from R1 to the most outer circumference R0. By this method, the high thermal conductive layer is formed in the inner area where the line velocity is slow, by which heat generated by laser beam irradiation is effectively diffused from the inner recording film to reduce the recording sensitivity of the inner area. Thereby, reading stability in the inner area can be maintained while writing sensitivity of the outer area can be improved.
