Title: Destaticizing method of electrophotographic copier
Inventor: OOSETO SEIICHI
IPC: G03G15/047
Filed: 1978-11-16
Abstract: PURPOSE:To eliminate uneven destaticizing and obtain the copy of good quality by so setting the exposure conditions of destaticizing lamps that the potentials of the non-image forming parts of the scaled-down electrostatic latent images becomes less than the potentials of the bright part of the image forming parts. CONSTITUTION:Equal-magnification and scale-down exposure is accomplished by an exposure optical system on a photosensitive drum 1. The optical path a shows the rays at the equal-magnification exposure and the optical paths b, c shown the rays at the scale-down exposure. A destaticizing device 2 is provided with two destaticizing lamps for removing unnecessary charges of the non-image-forming parts and is mounted in a casing 6 having a partition wall 5. Since the destaticizing lamps 3, 4 are so constituted as to be controlled of lighting according to the rates of scale- down, the potentials of the non-image-forming parts are controlled so as to become less than the potentials of the bright parts of the image-forming parts, whereby uneven destaticizing may be eliminated, the ground stains in the images prevented and the copies of superior quality obtained.

Inventor: HAYASHI KATSUMI
IPC: G01N21/64
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To output information capable of exactly discriminating a diseased tissue and a normal tissue from the measurement of the spectrum intensity of self-fluorescence generated from a living body by irradiating it with excited light. SOLUTION: A spectrophotometer part 20 measures the intensity of self- fluorescence Ka, which is generated from a viable tissue 100 by irradiating it with excited laser beam La, in specified wavelengths more than two, a standardizer 50 standardizes the intensity of the self-fluorescence Ka in the specified wavelengths, and a comparator 70 compares the standardized intensity of the self-fluorescence in each wavelength with reference standardized intensity provided from the normal or diseased tissue. Corresponding to the level of a difference between the intensity of the self-fluorescence and the reference standardized intensity, it is discriminated whether the viable tissue is normal or not.

Title: Positive-resistance temperature coefficient heating element
Inventor: TERAKADO MASAYUKI
IPC: H05B3/14
Filed: 1987-06-05
Abstract: PURPOSE:To stabilize the heating temperature and electric power for a long time by limiting the strength of bridging so that the adhesive and peeling strength of a positive-resistance temperature coefficient resistor composition material against a metal is 500 (g/25mm width) or more. CONSTITUTION:When an unbridged conductive composition material dispersed with the conductive fine powder is to be bridged in a metal adhesive crystalline polymer composition material containing carboxyl group, the strength of bridging is limited so that the adhesive peeling strength of a positive-resistance temperature coefficient resistor composition material against a metal is 500 (g/25mm width) or more. The stability of the resistance value of the positive- resistance temperature coefficient resistor composition material itself is obtained, and also the stable electric coupling end physical coupling with no skin layer of the surface can be obtained at the coupling portion with an electrode made of a metal material. The stable heating function can be maintained in the long- term usage.

Title: Driver for ac motor
Inventor: TACHIKAWA MAKOTO
IPC: H02J3/00
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To reduce the size and cost of a driver for AC motor by employing an AC reactor serving to suppress both harmonies and starting current, thereby decreasing the number of AC reactors. SOLUTION: While an AC motor 5 is driven through a power converter 1 with variable speed, an AC reactor 6 is connected between the power converter 1 and an AC power supply 8 in order to suppress harmonics generated through switching of the power converter 1. When an overcurrent flows through a PWM inverter 4 to cause a failure, rotational speed of the AC motor 5 goes to 0, and a restricted starting current flows from the AC power supply 8 to the AC motor 5 via the AC reactor 6. Since a single AC reactor 6 can serve to suppress both harmonics and starting current, the size and cost of the driver for AC motor can be reduced.

Abstract: PURPOSE:To prevent the exposure of a substrate by an external leakage light by a method wherein a light-shielding plate is shifted, and the driving of the light- shielding plate is stopped at the position where an opaque pattern is detected. CONSTITUTION:The distance to the optical axis of the light-shielding plate 21 can be adjusted using a driving device 22, a photo sensor 23 is shifted simultaneously with the light-shielding plate 21 and optically detects the opaque pattern to be used for light-shielding. A reticle 2 has a chromium thin film adhered on a glass substrate, and an opaque pattern for light shielding can be optically detected from the back side of the reticle.

Abstract: PURPOSE:To search quickly a radio wave source by using a specific transversal filter to a low pass filter within an adaptive loop. CONSTITUTION:The unit delay circuits (delay time Td) 111, 122... satisfy fd=1/Td with a clock frequency fd. A train of these unit delay circuits is divided every kp (2p+1: number of array element) pieces with addition of load devices 121, 122... to satisfy 2pi/omegas=kp/fd. Here, (k) is set so that the frequency fd is larger than double the highest working frequency handled.

Abstract: PURPOSE:To avoid the defective insulation by a method wherein a funnel shaped capture member with a baffle plate fitted to the end thereof is arranged in a duct with said baffle plate of a foreign matter capture body provided inside an outer tube turned in the upstream direction of SF6 gas. CONSTITUTION:SF6 gas is circulated in an arrow direction when driven by a gas blower 3. At this time, theSF6 gas running in a foreign matter capture body 10 firstly guided in the inner wall direction of an outer tube 11 by the action of a baffle plate 13 runs down along the inner wall in the downstream direction. Next, the stream of SF6 gas along the inner wall is obstructed by the inner wall of the outer tube 11 and the bottom part 12a of a capture member 12 so that eddy currents of SF6 gas may be produced on the parts near the ends of the baffle plate 13 due to the existence of return parts 15. Through these procedures, the impurity particles contained in the SF6 gas drop down into the space between the return parts 15 and the foreign matter cap-ture mamber 12 by the drivity action therebyenabling the defective insulation to be avoided.

Abstract: PURPOSE:To obtain an element isolation region by hydrolyzing raw material, the principal ingredient thereof is SiCl4, by an oxyhydrogen flame and depositing the particulates of SiO2 onto a semicondutor substrate and sintering the particulates. CONSTITUTION:SiCl4 at the rate of 100cc/min, H2 at the rate of 2,000cc/min and O2 at the rate of 3,000cc/min are forwarded to a burner, and the particulates of SiO2 are deposited onto the surface of the semiconductor substrate 1, to which grooves 2 are formed, by approximately 300mum thickness. Approximately six min is required for said process. When the whole is treated for 120min at 1,200 deg.C, transparent hard glass 5 is formed. When the back of the substrate is processed up to desired thickness, the substrate with the isolation region is completed. This method needs no thermal oxidation, and further the velocity of growth is faster only by one figure. The quantity of processing can easly be measured optically when the substrate is processed from the backs of the grooves because the transparent holder 5 is shaped after sintering.
