Title: Biasing method for resistor in semiconductor device
Inventor: MATSUOKA HIROTO
IPC: H01L21/822
Filed: 1990-10-30
Abstract: PURPOSE:To prevent leakage through a resistor by biasing the isolation zone for the resistor with a high-voltage source through a diode. CONSTITUTION:In a semiconductor device incorporating at least one P-type resistor 6, a diode 3 is formed with its anode connected to a highly stable voltage terminal 4 in the semiconductor device and with its cathode 2 for fiasing an isolation zone 7 for the P-type resistor 6. With this constitution, the voltage at a resistor terminal 1 is lower than that of a power source terminal 4, parasitic transistor 8 is reverse-biased and does not operate. On the contrary, if the voltage at the resistor terminal 1 is higher than that of the power source terminal 4, base current of the parasitic transistor 8 is interrupted by the diode. Therefore, the parasitic transistor 8 does not operate. As a result, the leakage through the resistance can be prevented.

IPC: C09K17/00
Filed: 1987-11-21
Abstract: PURPOSE:To easily treat an excretion by performing the treatment fermentatively in a treating tank by the use of a microorganism. CONSTITUTION:A livestock excretion slurry 16 is introduced into a treating tank 1, and a photosynthetic bacterium 19 is introduced into the tank from an inlet 6 for microorganisms. The slurry is stirred by the action of an air exposure pump 3 and, as a result, the photosynthetic bacterium acts on the excretion in the tank and, at the same time, adheres to bubble surfaces. The bacterium multiplies and accelerates the decomposition of organic substances into clean inorganic substances. The resulting inorganic bubbles 17 are smashed by the propeller of a defoaming device 8 and changed into a slurry, which is then fed to a predetermined place through a discharge channel. Owing to this construction, the slurry can be treated in a short time.
