Title: Frequency tracking device
Inventor: POORU BATSUKUNERU
IPC: H03J7/02
Filed: 1992-04-02
Abstract: PURPOSE: To improve the selectivity of the frequency tracking device employing a feedback. CONSTITUTION: A frequency conversion means 32 has an input 30, and its output is connected to a filter and demodulator 34 that has two outputs, a frequency output 36 and an amplitude output 38. The output 36 connects to a variable gain stage 44 via a low pass filter 42. A output of the gain stage 44 is fed to a feedback input of the frequency conversion means 32. The amplitude output 38 of the filter and demodulator 34 is fed to a control input of the variable gain stage 44. The amplitude output 38 of the filter and demodulator 34 is used to change an amplitude of a feedback signal of a frequency tracking loop. In the case of using this device for an audio FM radio receiver, when an input signal gets weaker, the means 32 stops trial of tracking to the input signal.  The effects by this device are that noise amplitude in the output signal is reduced and that the receiver is less fixed to an undesirable signal resulting from seeking adjacent frequency bands.

Abstract: PURPOSE:To prevent a recording medium from being eternally deformed by providing a pad member having a through hole for passing an airflow against the recording medium and an airflow controlling member freely attachably and detachably provided at the through hole on the opposite side of the pad member to the recording medium to be disposed. CONSTITUTION:When the recording medium 2 is commenced to travel in the direction of an arrow (x) at the time of starting the titled recording and reproducing device, an elastic member 7 is under the state of compression, while the airflow controlling member 6 is situated in an ascended position 6A as shown in the figure with a two-dot chain line, where a center part 6a of the airflow controlling member 6 blocks up the through hole 3 of the pad member 1 from the bottom. Then, when the recording medium 2 under such a circumstance is started to travel in the direction of the arrow of (x), air inside the through hole 3 is dragged out to the outside by the recording medium 2, and moreover because of less volume of an inflow of air into the through hole 3, a negative pressure is generated in this through hole 3, so that the recording medium 2 starting for travel is sucked by the pad member 1 to contact closely with a magnetic head 4. When a traveling speed of the recording medium 2 attains to a fixed speed, the airflow controlling member 6 descends to allow the through hole 3 to open up.

IPC: B62D15/02
Filed: 1987-04-03
Abstract: PURPOSE:To reduce unnecessary consumption of a source power by detecting ON and OFF of a main source switch so as to put a display unit in the state of non-operation at the time of OFF. CONSTITUTION:When it is detected that an ignition switch 16 of a main source switch turns OFF, an output Du of a switch ON/OFF detection circuit 17 is inverted to 0. Thereby a register for a steering direction display unit 11, which is provided in a controller having a microprocessor or the like incorporated, is cleared and the display unit 11 is put in the state of non-operation. Therefore the power of a battery 15 is not consumed for display. Meanwhile, an output Vc of the controller is also inverted to 0, and a minute power of a prescribed duty ratio is supplied to a displacement detector 5 through a source control signal generating circuit 20. By the detector 5 driven intermittently, detection of a steering amount after the main power source is turned OFF, as well as storage of the detected amount in a register, is executed. By this constitution, unnecessary consumption of a battery source power can be reduced.

The distance from the transmitter a1 to the receiver b1 through the reflection point (f) is represented as a function of the distance between the mid-point M and reflection point (f) and specific simultaneous equations constituting a reflected- wave scanning time curve are solved to find the sound speed and distance in the medium. Further, the rotary shaft 21 is rotated on the axis of the bore hole 1 to find distributions of the distance from the center M to the reflection point (f), sound speed, and the flow speed of the medium over the entire periphery of the wall surface 2.
