Title: Channel selection circuit
Inventor: MINAZU KATSUTO
IPC: H03L7/197
Filed: 1990-01-29
Abstract: PURPOSE:To realize this channel selection system operated at high speed and with high frequency accuracy by decreasing the number of stages of frequency division until a voltage is stabilized to a normal tuning voltage in accordance with a designated channel at the time of channel selection, and increasing the number of stages of frequency division at the final pull-in stage. CONSTITUTION:When a channel to be selected is designated and the channel selection of the channel is started with a normal frequency f0, switching circuits 18, 19 are operated by being set to (a) sides with a control signal from a microcomputer 13. Therefore, as the input to a phase comparator 10, the phase of the output of a 1/n-frequency divider 8 is compared with that of the output of a 1/x-frequency divider 9. After the tuning voltage 4 is stabilized, the microcomputer 13 varies a frequency division ratio (n) based on an AFT signal 14, and performs a signal retrieval operation so as to tune the frequency to that of a real broadcast signal. In such a manner, convergence can be performed in step with low frequency change based on a large number of stages of frequency division, and it is converged to a state nearer to a signal frequency f0'.

Title: Air-tight package for electronic component and piezoelectric vibrator using the same
Inventor: OKAMOTO MAKOTO
IPC: H03H9/02
Filed: 1990-01-31
Abstract: PURPOSE:To improve the shock resistance by specifying the length-to-width ratio and the length-to-thickness of a ceramic substrate and a ratio of the length to a thickness. CONSTITUTION:A ratio L/w of a length L to a width (w) of a ceramic substrate 2 is selected to be <=3 and a ratio L/t of the length L to a thickness (t) is selected to be 13 or below. When the thickness (t) of the ceramic substrate 2 is <=0.8mm (with side ratio L/t is <=15.6), damage or destruction is generated on a low melting point glass of a bonding face or the ceramic substrate 2. On the other hand, when the thickness (t) is >=1mm, even when a torsion or the bonding of the circuit substrate at shock is imparted directly, the brittle fracture is prevented by using the strength of the ceramic substrate 2 itself. Thus, the shock resistance is improved and the reliability is enhanced.

Title: Gas leakage warning device
Inventor: KOUDA KAZUHITO
IPC: G01N27/12
Filed: 1981-02-18
Abstract: PURPOSE:To issue the warning by providing a voltage comparator at the output terminal of a gas sensor, operating a warning circuit, and detecting the decrease in the output voltage of the gas sensor when the wires of the gas sensor are broken and a heater is broken. CONSTITUTION:The gas sensor 3 is heated to a certain temperature by a heater 4. When either of the wires 8 and 9 or a heater 4 is broken in this state, heating by the heater 4 becomes impossible, and the temperature of the gas sensor 3 is decreased. When the temperature is decreased, the resistance value of a semiconductor electrode element 5 becomes high, and the current flowing the element 5 is decreased. When the current is decreased, the terminal voltage across a resistor 11 is decreased, the voltage value becomes lower than a specified differential voltage 15(V2), and the output of the voltage comparator 14 is shifted to a high level from a low level. As a result, a transistor 22 is turned ON, and the warning circuit 19 is operated. At the same time, a light emitting diode 24 is lit to display that the warning for the breakdown of the wires 8 and 9 or the breakdown of the heater 4 is issued.
