Abstract: PURPOSE:To store only a station in which a broadcast signal, and also a stereo signal are present automatically, by starting up an automatic frequency searching means, and discriminating a signal representing the presence of the broadcast signal, and the signal representing the presence of the stereo signal. CONSTITUTION:The titled system is operated in such a way that a circuit 150 is added on a system which starts up an automatic frequency searching by a broadcast frequency automatic storage starting up switch, and stores only the frequency from which a signal 110 representing the presence of a broadcast station is outputted, by a stop signal detection circuit 105 through an intermediate frequency amplifier part 103, and an automatic storage is performed by a signal 113 representing the existence of both the signal 110 representing the presence of the broadcast station, and a stereo broadcast station signal 111 outputted from an MPX demodulation circuit 106. In other words, a switching is performed by a signal 112 based on whether it is decided as the presence of the broadcast station only by the signal 110, or whether it is decided as the presence of the broadcast station by both signals 110, and 111.

Title: Support structure and support method of piezoelectric vibrator
Inventor: OOHIRA NAOYA
IPC: H03H9/19
Filed: 1984-06-07
Abstract: PURPOSE:To ensure the stability of a frequency over a long time by using an ultrasonic wave heat press-contacting method for bonding between the head of a support member and a piezoelectric vibrator and fixing a terminal and the support member by welding so as to attain vacuum baking at the high temperature. CONSTITUTION:The head 2 of the support member 1 and a crystal element plate 4 are bonded incorporatedly by applying ultrasonic wave thermal pressing to them via an aluminum thin plate 13. Further, the support member 1 and the terminal 6 are fixed at a bonding part 5 by using a welding means.

Title: Ink jet recorder
Inventor: SATOU KAZUHIKO
IPC: B41J2/01
Filed: 1983-06-29
Abstract: PURPOSE:To make it possible to confirm the presence or absence of the jet of ink particles even if recording is being made by such an arrangement wherein electric charge is given to ink particles to be jetted out through an electrode at the time of their spouting and electrical change of ink particles caused by their flying is detected through an electrode. CONSTITUTION:Simultaneously when an ink particle 3 is formed as ink is spouted from a nozzle 1, an electric charge of which polarity is contrary to that of a DC voltage given to an electrode 9 is induced in the ink particle 3. As the charged ink particle 3 flies and approaches the electrode 9, an electric charge of which polarity is contrary to that of the electric charge of the ink particle 3 is induced in the electrode 9 and the electric charge disappears as the ink particle 3 moves away from the electrode 9. A current variation to be induced in the electrode 9 in connection with the flying of the ink particle 3 is converted into a voltage (a) by a current/voltage conversion circuit 12 through a condenser 11 and it is amplified by an amplifier 13. After its noise is removed by a lowpass filter 14, the voltage is compared with a reference voltage set in a reference voltage generator 15 in advance at a comparator 16, and if the output (b) of the low pass filter 14 is larger than the reference voltage, the comparator 16 generates an ink particle detection signal (c).

In this case, since, when air passes an ozone generating device 15, a high electric field is applied between a cylinder electrode 21 and a needle-form electrode, a part of oxygen in air is converted to ozone. Since fuel is burnt in a way that ozone is operated togetherwith air. Since fuel is burnt by operating ozone togetherwith oxygen, combustion efficiency is improved, the output of the engine 1 and fuel consumption are improved, and CO density in exhaust gas is reduced.
