Title: Method for detecting edge of photographic paper
Inventor: TAKAHASHI TOKUJI
IPC: G01N21/89
Filed: 1983-07-06
Abstract: PURPOSE:To distinguish an edge part and a defective part from each other clearly by extracting a frequency component corresponding to an unapplied part of the edge and a high frequency component which is changed in the edge part. CONSTITUTION:The light from a light source is irradiated to a photographic paper in the breadthwise direction by the flying spot system while carrying the photographic paper, and the reflected light from the surface of the photographic paper is converted electrically, thus obtaining the defect detection signal. The frequency component corresponding to the unapplied part of the edge out of this detection signal passes through a band-pass filter 5 and passes through a comparator 6 to output a pulse. The high frequency component which is changed rapidly on boundaries between the edge and an applied part passes through a high-pass filter 7 and passes through a comparator 8 to generate a pulse. These pulse signals are superposed onto each other by a timing circuit 9 and an AND circuit 10 to detect the edge.

Title: Collection of dry distillation gas of waste tire chip
Inventor: OKANO HIROYUKI
IPC: C10G1/10
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To efficiently utilize the dry-distilled gas of waste tire chips as a fuel for combustion devices by dry-distilling the waste tire chips by the use of simple installations. SOLUTION: A plurality of batch type dry distillation ovens are alternately or successively operated to dry-distill waste tire chips. Therein, the dry distillation ovens are operated in such a partially mutually overlapped state that the unstable generation of a gas in the early operation period of the next distillation oven is finished at an unstable gas generation-initiating time in the final operation period of the first operated dry distillation oven. The stable gas thus continuously generated is used as a main fuel for one or more other combustion devices. The unstable gases generated in the early and final operation periods are effectively utilized as auxiliary fuels for the combustion devices. The combustion periods of the dry distillation ovens are sufficiently elongated to burn up the waste tire chips, thus reducing the residue ash.

Title: Combustion chamber structure of internal combustion engine
Inventor: YOKOYAMA JUNICHI
IPC: F02B23/08
Filed: 1989-05-17
Abstract: PURPOSE:To intensify a vertical swirl as well as to improve intake and exhaust efficiency by setting the skyline position of a combustion chamber wall surface where cone surfaces leading to cone-shaped seat surfaces are crossed at right angles so that it is brought closer to exhaust valve side rather than intake valves. CONSTITUTION:A combustion chamber wall surface is formed by cone surfaces 9a, 9b, 10a, and 10b leading to cone-shaped seat surfaces of each valve seat of intake valves 13a and 13b and exhaust valves 14a and 14b. The position of a skyline 19 of the combustion chamber wall surface where the cone surfaces 9a, 9b, 10a, and 10b are crossed at right angles is set so that it is brought closer to the exhaust valves 14a and 14b side rather than the intake valves 13a and 13b. By this, as the cone surfaces 9a and 9b extend at length in the direction to which an intake main stream flows, the intake made stream is smoothly guided without lowering flow speed, and a powerful vertical swirl with small attenuation can be generated in the combustion chamber. Also, as flow of combustion gas in an exhaust stroke is smoothly guided toward the exhaust valves 14a and 14b without generating vortexes along the cone surfaces 10a and 10b, volumetric efficiency can be improved.

Title: Charging method of raw material in bell-less type blast furnace
Inventor: JIYOUKOU TADATSUGU
IPC: C21B5/00
Filed: 1983-07-07
Abstract: PURPOSE:To decrease the grain size segregation of the charge in a bell-less type blast furnace and to improve the utilizing rate of reducing gas by dividing the charging raw material for one charge in the hopper at the top of the blast furnace to plural times and charging successively the materials from the furnace wall side to the central direction by a swiveling chute. CONSTITUTION:The raw material for one charge stored in a hopper 3 at the top of a blast furnace is divided to plural times and the divided materials are charged into the blast furnace by a swiveling chute 6. Charging of the raw material for one charge in the hopper 3 by dividing the same to, for example, twice, is accomplished by swiveling and tilting the chute 6 to charge and distribute the raw material so as to charge first the fine grained raw material from the furnace wall side to the central side then closing once a raw material discharge gate 4 and stopping the charging of the raw material. The charging of the raw material from the furnace wall side is thereafter restarted to charge the raw material including large lumps from the furnace wall to the center thereby decreasing the grain size segregation of the raw material in the blast furnace.

Title: Image-forming apparatus
Inventor: NAKAMURA YUTAKA
IPC: B41J13/00
Filed: 1990-05-14
Abstract: PURPOSE:To enable forming images in both upper and lower stages at the same printing speed by equipping a plurality of paper-feeding carrier paths differing in space from a paper-feeding part to a waiting part and by causing respective carrier means to carry a transfer paper in the same period of time from the paper-feeding part to the waiting part. CONSTITUTION:When a printer controller 32 receives a start signal, the controller carries a paper P out from a paper-feeding cassette 18 while a clutch 24a drives by a control signal from a printer controller 32 to rotate a carrier roll 21 at high speed to convey a paper P' in the direction of a standby plate 11. When the paper P' comes directly under a waiting paper switch 35, a high speed-controlling clutch is turned OFF and the tip of the paper P' comes into contact with the standby plate 11 to stop. Then, the standby plate 11 in contact with the paper P' comes off by driving of a clutch 24b, the carrier roll rotates at low speed thereafter, and the paper P' is conveyed at the carrier speed of the paper P carried out from a paper-feeding cassette 8 in the upper stage. Therefore, even if the paper P' is conveyed from the paper-feeding cassette 18 mounted as option, the paper can be conveyed to the standby plate 11 in the same period of time as that in the case of conveying the paper from the paper-feeding cassette 8 without delaying the carrier speed.
