Filed: 1982-11-17
Abstract: PURPOSE:To reduce surely multi-path disturbing noise by rectifying an output of a detecting circuit which detects an intermediate frequency signal, and controlling the separation degree of a stereo demodulating circuit by a synthesized signal of the detected output and the rectified output. CONSTITUTION:A voltage in response to an electric field strength is outputted to a terminal (a) of an intermediate frequency amplifier circuit 5, detected at a diode 9 and outputted to a terminal (b). When multi-path disturbance is received, a DC voltage VD and an AC voltage va are applied to the terminal (b), the voltage va is extracted by a capacitor C12, rectified at diodes 13, 14, C15 and a resistor 16 and converted into a DC voltage. If the multi-path disturbance is large and the voltage va is large, the potential at a point (c) is increased, the output impedance of transistors 17, 18 is decreased, and the potential at the terminal (b) is reduced. Then, the separation of the stereo demodulating circuit 6 is decreased and the multi-path disturbing noise is decreased.

Title: Lightweight type highly rigid panel
Inventor: ODA MITSUAKI
IPC: E04F13/12
Filed: 1998-07-17
Abstract: PROBLEM TO BE SOLVED: To provide a lightweight type highly rigid panel by a method wherein a plate is concaved and convexed in the thickness direction thereof locally to increase the bending rigidity even if the plate maintains the same thickness so that vibrations can be reduced, with the result that noises are decreased. SOLUTION: Irregularities are formed on both sides of a panel 1, in both lateral and longitudinal directions thereof. Thus, bending rigidity of the panel 1 is increased even if it maintains the same thickness so that vibrations can be reduced with the result that noises can be decreased. In this case, if irregularities are formed closely, in a staggered arrangement, so as not to form a flat portion, other than the irregularities, in a straight line form, a node of a straight vibration is not formed, and hence the natural frequency of the panel increases so that vibration-damping properties can be enhanced.

Title: Magnetic recording and reproducing device
Inventor: KONDO MASANORI
IPC: G11B20/04
Filed: 1989-08-05
Abstract: PURPOSE:To drastically improve the handling of the device by automatically turning noise reduction on/off at the time of reproducing without recording the switching state of the noise reduction in detail at the time of recording. CONSTITUTION:At the time of recording with Dolby-ON, a recording sound 1 is encoded by a Dolby circuit 3 with a Dolby-ON signal 11 of a recording system and recorded by a sound head 8. Then, at the time of Dolby-ON of the recording system, a carrier signal 13 is superimposed on a CTL signal 14 of the recording system, and a carrier superimposing CTL signal of the recording system is recorded by a CTL head 17. On the other hand, at the time of reproducing, a carrier superimposing CTL signal of a reproducing system to be obtained from the head 17 is separated by filters 19 (LPF) and 20 (BPF) into a carrier signal 22 of the reproducing system and a CTL signal 15 of the reproducing system. Then, when the carrier signal of the reproducing system is detected by a carrier detecting circuit 23, a Dolby decode on/off switch of the reproducing system is operated. By this method, it is obviated to have a fear of the reproducing state under wrong noise reduction at the time of reproducing.

Title: Processing liquid supplying method for automatic developing machine for photosensitive material
Inventor: OSE JUNICHI
IPC: G03D3/06
Filed: 1988-08-16
Abstract: PURPOSE:To hold the liquid composition in a processing tank constant by mixing original processing liquid and a processing solvent to a specific ratio right before thy are supplied into the processing tank and thus preparing and supplying processing liquid into the processing tank. CONSTITUTION:A supplementary water (processing solvent) tank 40 and an original processing liquid tank 44 are provided on the bottom wall 12A of a machine frame 12. A level sensor 18 detects the liquid level in the developing tank 18. When the developing tank 18 contains a specific amount of liquid developer, neither a pump 48 nor a pump 54 is put in operation and nether supplementary water nor original processing liquid is supplied to the developing tank 18, but when the amount in liquid developer in the developing tank 18 is not the specific amount, the pumps 48 and 54 are operated for specific times. The specific times of those pumps 48 and 54 are different and correspond to the mixing ratio of the supplementary water and original processing liquid and thus a difference in supply amount is generated between the pumps 48 and 54 to set the mixing ratio to the specific ratio. Consequently, the liquid composition in the processing tank is held constant.
