Title: Output holding circuit
Inventor: OKUMURA TAKEKIYO
IPC: H02M3/00
Filed: 1990-05-28
Abstract: PURPOSE:To prevent an erroneous operation of an output stage of a switching regulator even if noise of a certain degree is superposed by connecting a capacitor and controlling the output of a first controller based on the terminal voltage of the capacitor. CONSTITUTION:A transistor Q1 constitutes a switching circuit, a transistors Q1 - Q6, diodes D1, D2 and resistors R3 - R9 constitute a first controller, transistors Q7, Q8 and resistors R10 - R12 constitute a second controller, and a diode D3 constitutes a third controller. A T terminal is grounded when the protection of the output stage of a switching regulator is not required, and opened when it is required. When the T terminal is grounded, the transistor Q7 is turned OFF, and the transistor Q8 is turned ON. A '0' holding signal is forcibly outputted from an output terminal OUT. Thus, even if any noise is superposed on a reference voltage, an erroneous operation can be prevented.

Title: Gas sensor using piezoelectric element and measuring method of concentration of gas using the gas sensor
Inventor: HANASATO YOSHIO
IPC: G01N5/02
Filed: 1992-05-06
Abstract: PURPOSE:To obtain a highly sensitive gas sensor which has superior selectivity to the kind of gases by measuring the difference of oscillating frequencies of output signals from a piezoelectric element carrying an organic film of the non-selective adsorption characteristic which does not show high adsorption characteristic to a specific gas and a piezoelectric element carrying an organic film of the selective adsorption characteristic showing high adsorption characteristic to the specific gas. CONSTITUTION:Quartz oscillators 11a, 11b are oscillated by the signal from an oscillating circuit 14, with two kinds of corresponding signals generated. Since two kinds of organic films 12, 13 have different adsorptivities to, e.g. NO2 gas, the gas is adsorbed to the surface of the organic film 12 when the NO2 gas is brought in touch with the film, thereby generating the change in mass of the organic film 12. As a result, the oscillating frequency is changed. The oscillating frequency of each vibrator 11a, 11b is counted by a frequency counter 15. The difference of the counted frequencies is operated by a frequency difference operating device 16 and sent outside as an output signal 16a to calculate the concentration of the NO2 gas.
