Title: Dc/dc converter
Inventor: IRIYAMA KENJI
IPC: H02M3/155
Filed: 1993-04-15
Abstract: PURPOSE:To reduce a power loss at turn-on or turn-off, by using a resonance control circuit for interrupting current resonance of a resonance circuit while DC power is turned on and off in a cycle from continuity to breake through a relay circuit. CONSTITUTION:When energy stored in a resonance inductance element 3 is discharged through current resonance and a diode 8 is reversely biased, the resonance is interrupted for a time and the resonance energy is stored in the resonance capacitor 7. During the breaking time of the resonance, a DC/DC converter functions similarly to an ordinary on-on converter at an on-state so as to reduce a power loss. Then, a sub-transistor 9 is turned on to discharge the energy stored in the resonance capacitor 7. Then, a current flowing in a main transistor 4 is reduced, and at the same time, a power loss at the turn- off is also reduced.

Abstract: PURPOSE: To provide a nonstriking printing system that produces ions. CONSTITUTION: This method and device can have one or more image toner processing stations on a conductive substrate. When a large number of stations provided with image and toner processing means respectively are used, a complex image aligning constitution is avoided. A dielectric layer used is with a thickness of at least 5.08μm (0.2mil) and processed for an image, developed and fixed. The dielectric layer used is a dielectric layer or a layer made of resin in the same system as that used in plural dielectric layers, formed like the layer or covered and then, removed from a system. The layer after being processed for the image and covered can be attached to a base material such as a tile and a wall paper, before or after this method is completed. Covering is for reinforcing the dielectric layer, in addition to the actual covering of the image.  The final colored image (or single color) is removed from the printer, after covering is attained like the layer.

IPC: H04N1/60
Filed: 1994-04-30
Abstract: PURPOSE:To simplify the device configuration and to reduce the cost by using a means separating a color of color information and a means separating a 2nd color in common as a color signal separator means. CONSTITUTION:A control section 210 sets a chroma signal corresponding to a color of an image formed by a color developer detected by a color identification sensor 150 as a C signal to a color separation processing section 203. The processing section 203 receives plural chroma signals from an image read means 109 and separates the signal into a BK signal representing a 1st color and the C signal representing a 2nd color. An area discrimination section 204 uses the C signal outputted from the processing section 203 to discriminate an image area on an original image. An image edit section 205 applies different image processing to images at the inside and the outside of the image area discriminated by the discrimination section 204. Thus, the configuration of the copying machine provided with a configuration detecting the image area specified by a color marker or the like and in which two color image is formed is simplified and the device cost is reduced.

Title: Method and apparatus for spatial filtering of digital image decoded by block conversion
Inventor: DANIERU DOUBUIMUU
IPC: G06T5/20
Filed: 1993-04-19
Abstract: PURPOSE: To reduce or remove the disturbance effect of digital image before projecting the image on a screen after encoding/decoding by block conversion. CONSTITUTION: The block conversion causes the discontinuity of luminosity levels concerning pixels D and E in the border area of blocks BL1 and BL2. The discontinuity of these levels is detected from a change in the signs of two luminosity gradients respectively calculated between the levels of two pixels C and E adjacent to each pixel D in the given border area. A luminosity level NL of the pixel D in the border area is corrected by the jump ED of discontinuity equal with the absolute value of difference in the arithmetic average with the luminosity level of adjacent pixel by a discontinuity correction rate FCD evaluated corresponding to a quantization pitch allocated to the block BL1. Next, the block BL1 is corrected as a whole for reducing luminosity level difference caused by encoding/decoding between two adjacent blocks BL1 and BL2.

Abstract: PURPOSE:To prevent fuel from penetrating into an air-liquid separation chamber, by installing a cutoff valve opening when fuel inside a fuel tank arrives, in a pipe whose inner end is the nearest to the air-liquid separation chamber, among plural branch air vent pipes. CONSTITUTION:An air-liquid separation chamber 1 is made up of an inversed U-shaped pipe provided with two upright pipes 1a and 1b closing each lower end, one main air vent pipe 2 leading to the atmosphere and three branch air vent pipes 3-5 leading to a fuel tank T are all connected to the said chamber 1.
