Title: On-vehicle radio receiver
Inventor: TAKAGI AKIO
IPC: H03J5/02
Filed: 1994-02-16
Abstract: PURPOSE:To prevent the reception of broadcast programs of the same content by storing identification information of a broadcast station selected by one tuner and executing switching control when the identification information differs from identification information selected by the other tuner. CONSTITUTION:An audio signal comparator circuit 9 compares waveforms of audio signals outputted from a 1st tuner T6 and a 2nd tuner T7 in real time and discriminates the difference to provide a prescribed discrimination signal to a station reception control section 10 of a microcomputer 12, the control section 10 selects automatically a broadcast station via an on-vehicle antenna 5 by using a seek command signal and an audio signal of the selected broadcast station is outputted to the circuit 9, which outputs a frequency signal to the control section 10. The circuit 9 discriminates whether or not the broadcast stations selected by the tuners T6, T7 are broadcast stations of the same group and provides an output of a discrimination signal. Upon the receipt of an automatic storage operation signal, the control section 10 gives a seek command to the tuner T6 and stores the identification information selected by the tuner T6 to a memory 11. The processing above is applied similarly to the tuner T7. Since the broadcast stations of the same broadcast program are not stored in duplicate, trouble of reception of broadcast stations whose broadcast content is the same is avoided.

Title: Recording and reproducing device for low-frequency conversion color signal
Inventor: ABE KENJI
IPC: H04N9/84
Filed: 1985-03-04
Abstract: PURPOSE:To reduce dirt of a main signal by setting a phase pattern of a recorded chrominance signal so that the crosstalk from left-right magnetic tracks is cancelled together with the main signal. CONSTITUTION:In reproducing a signal by a wide magnetic head, since crosstalk takes place from not only a magnetic track for the main signal from but also left/right magnetic tracks, the relation of detection signal S is expressed as S = main signal + crosstalk from left track + crosstalk from right track. At reproduction, the magnetic head is moved in broadwise direction of the magnetic track and a pilot signal of the adjacent track is selected for the main signal track by using four kinds of pilot signals f1-f4 recorded on each magnetic track so that the crosstalks from the left/right magnetic tracks are made nearly equal. Thus, the crosstalks are cancelled together and only the main signal is reproduced.

Title: Cleaning device of coolant liquid
Inventor: KODERA TERUMI
IPC: B01D29/62
Filed: 1982-03-17
Abstract: PURPOSE:To maintain the filtering capacity of a cleaning device at a high level for a long period of time, by arranging the prescribed number of filter members, having triangular cross-sections, parallelly at extremely small intervals by putting all their bases on the same plane in order, and eliminating the need for exchanging a filter by using the filter plate formed by said means. CONSTITUTION:A coolant liquid is introduced to the lower chamber 13 of a treating tank 10 and is raised to an upper chamber 12. At that time, among foreign matters such as nonmagnetic cut chips which are mixed into the coolant liquid, the foreign matters which are larger in size than the width of slit of a filter plate are separated. Further, the foreign matters which are smaller than the slit width are also separated because passage of said smaller matters is rejected by the foreign matters sticking to the lower surface of the plate 1. Furthermore, the flow speed of the foreign matters after having passed through the slits are lowered between the slanting surfaces of the filter members 2 to stick said matters to the members 2. These foreign matters are scraped off timely to prevent clogging.

Then, the signal S5 is inputted to a counter 6 and begins to be counted, and the counted number is inputted to an address of ROM7. Then a digital signal proportional to a frequency is written corresponding to the counted number. Consequently, when the counted number with pulse width is inputted, a desired digital signal output is outputted from the ROM7.
