Title: Instrument for measuring concentration of particulate matter in piping
Inventor: YOSHIZAKO HIDEHISA
IPC: G01F23/28
Filed: 1988-10-21
Abstract: PURPOSE:To make prompt measurement by providing >=1 pairs of ultrasonic oscillators and receivers to the circumference of a piping, measuring the attenuation quantity of the ultrasonic waves in the ultrasonic propagation routes formed therebetween and detecting the concn. of particulate matter in accordance with the attenuation quantity. CONSTITUTION:Three pairs of the oscillators 3 and receivers 4 are mounted to the outer side of a circular piping 1 in which pulverized coal and the air for transporting this coal flow in the form of solid-gas two-phase flow 2. The instrument is constituted in such a manner and the signal from a computer 7 is amplified by an amplifier 6 to drive the transmitters 3. The ultrasonic waves received by the receivers 4 are converted to electric signals by the receivers. The electric signals are amplified by an amplifier 6A and are returned to the computer 7. The attenuation quantity of the respective propagation lines connecting the oscillators 2 and the receivers 4 from the reception level is determined at this time and the concn. of the powder is detected from the calibration chart of the previously measured ultrasonic transmittance and the concn. of the pulverized coal. The detected concns. are respectively displayed on a distribution display device 8 and an average value display device 9. The pressure drop in the piping is eliminated in this way and the errors by the moisture in the fluid are eliminated as well.

Abstract: PURPOSE:To prevent the contamination of an electrostatic charge wire, etc. and the pinholing of an image carrying body surface by providing a flexible member which is electrostatically charged to the polarity reverse from the polarity of a toner on the down stream side of a cleaning blade when viewed in the traveling direction of the image carrying body so as to contact slidingly with the image carrying body. CONSTITUTION:The residual toner remaining on the photosensitive body without contributing to the transfer in a transfer position is brought to the position of a cleaning device 9 as a photosensitive body rotates. The toner is removed from the surface of the photosensitive body 1 by the cleaning blade 9a. The brush-shaped member 12 which consists of the fibrous flexible member and is electrostatically charged to the polarity reverse from the polarity of the toner is brought into sliding contact with the body 1 on the down stream side of the blade 9a. The toner and other pulverous particles which are not removed by the blade 9a are thereby mechanically removed; in addition, the effect of removing the same is electrostatically accelerated, by which the surface of the image carrying body entering the next image forming stage is thoroughly cleaned and the stable image quality is maintained for a long period of time without the pinholing in the photoconductive layer consisting of amorphous silicon.

Title: Large scale integrated circuit device
Inventor: SAITO TOMOTAKA
IPC: H01L21/768
Filed: 1984-12-18
Abstract: PURPOSE:To prevent latchup by a method wherein high-concentration impurity- diffused layers are provided in opposing locations of chip regions or in locations out-side a chip region and the layers are biased on a proper power source level. CONSTITUTION:An N<+> layer 41 is provided between regions A, B equivalent to chips and a bias voltage VDD>0 is applied thereto. Application of a surge to a P<+> layer 29 from a pad 42 results in the flow through a substrate 27 of a base current i1 of a parasitic PNP element 33 through an N<+> layer 25 biased with the voltageeVDD, which results in a collector current i2 allowing latchup to easily take place. Insertion of an N<+> layer 41 moderates the potential gradient within the N-base of a parasitic lateral PNP element, reducing the current gain in the element 33 and thereby preventing latchup. In case of a P type substrate, the substrate is biased on a power source VSS level by using the P<+> layer 41.
