Title: Electrostatic precipitator
Inventor: IZAKI KATSURA
IPC: B01D46/42
Filed: 1986-10-17
Abstract: PURPOSE:To allow a user to easily and surely know the lowering in the capacity of a filter material, by preliminarily printing a colored character having a color almost equal to the color generated as the result of the discoloration of the filter material due to contaminated air on the surface of the filter material arranged on the downstream side of a charge part. CONSTITUTION:When a fan 3 is rotated by a motor 2, contaminated air 10 is sucked from a suction port 7 and charged when passing between the opposed electrode 5 and discharge electrode 6 in a casing 1. The charged contaminated air 10 is adsorbed by a rearward filter material 4. Herein, when a colored character having the color which will be generated as the result of the discoloration of the filter material due to the contaminated air is preliminarily printed on the filter material, the filter material 4 is discolored so as to have the same color as the colored character 8 during the use of an electrostatic precipitator and the reading of the colored character 8 becomes impossible at last. A user surely knows that this period is the limit of the capacity possessed by the filter material 4.

Title: Internal voltage generation circuit of semiconductor memory device
Inventor: KIN SANSHIYU
IPC: G11C29/06
Filed: 1995-09-26
Abstract: PROBLEM TO BE SOLVED: To rapidly and accurately perform a burn-in test of a performance and to improve the productivity by a constitution of a circuit to previously increase the internal power source voltage at the time of operating a sense amplifier and to compensate the voltage drop. SOLUTION: A voltage level sensor 200 is operated by a reference voltage Vref for bias generated from a first reference voltage generator to detect an external voltage Vcc at the time of experimenting a burn-in. A second reference voltage generator 300 amplifies the output voltage level from the sensor 200 at a predetermined ratio to generate a reference voltage Vref2. A differential amplifier 400 for stand-by mode compares the voltage Vref2 with an inner power source voltage Vint, and regulates the voltage Vint. An active differential amplifier 500 compares a reference voltage Vref2 with the voltage Vint at the time of operating the sense amplifier, and compensates the drop of the power source voltage Vin. Thus, even if an error occurs, the conversion and returning operation between the normal operation and burn-in operation modes can be rapidly conducted.
