Title: Method of and device for adjusting recording parameters
Inventor: BAKX JOHANNES LEOPOLDUS
IPC: G11B5/00
Filed: 1996-03-07
Abstract: In the method and the device disclosed herein at least one record-carrier-dependent parameter (Is), which influences the quality of the recorded information pattern (58, 59), is adjusted. In determining the optimum setting of the parameters (Is) a calibration area (21) is selected from a number of predetermined calibration areas (21a,..., 21d). The selected calibration area (21) is provided with test patterns for different settings of the parameter. On the basis of the test patterns thus formed the optimum setting of the parameters is determined in accordance with a predetermined criterion. The parameters are adjusted in accordance with said optimum setting during the recording of the information patterns (58, 59). Each time that an optimum setting is determined an auxiliary pattern is formed in an auxiliary area (22) assigned to the calibration area (21), which auxiliary pattern indicates that test patterns are present in the associated calibration area. Each time that the optimum setting is determined the test area to be used is selected on the basis of the auxiliary patterns formed in the auxiliary areas (22a,..., 22d).

Title: Intraoral dental radiographic film packet improvement
Inventor: LIESE ELMER WILLIAM JR
IPC: G03B42/04
Filed: 1996-05-09
Abstract: A comfort-enhancing improvement upon a known dental film packet having sensitized film and protective opaque sheets enclosed by a light-tight envelope that includes an opposed pair of generally parallel walls covering the sheets, those walls being joined together along facing marginal areas thereof surrounding the sheets so as to define a main body portion and a perimetric edge portion of the envelope. The improvement comprises a pliant bead of substantially non-porous, non-toxic, polymeric elastomeric material, preferably a silicone resin, that is molded in situ around at least part of the perimetric edge portion to encapsulate that part of the edge portion with such material and thereby provide the encapsulated part with a softer, smoother, and more rounded peripheral surface. In the molding process illustrated, the polymeric elastomeric material is injected under pressure into a mold peripheral-channel of circular cross section surrounding the envelope edge portion; and the mold is then heated for optimal, low-temperature, controlled curing of the bead formed therein.

Title: Ink feed controlling method in printer
Inventor: SHIBATA MASAO
IPC: B41L13/18
Filed: 1981-01-07
Abstract: PURPOSE: To facilitate feeding of ink and to obtain a printed matter which is finished in an uniform manner, by a method wherein an amount of slip produced between a roller for feeding ink and an idler roller, brought into press contact with the roller, is detected to control an ink feeder according to the detection.  
     CONSTITUTION: Idler rollers 32 (32a, 32b, 32c), brought into press contact with an ink kneading roller 26, turns in a given position in a condition that it is pressed against a holding member 35 through the elastic force of spring 36W36" in case a sufficient ink is adhered to the ink kneading roller 26. Then, a slip in an axial direction is produced between the idler rollers 32 and the ink kneading roller 26. If the roller is short of ink, a friction factor between the idler rollers 32 and the kneading roller 26 increases, the roller 32 moves rightward against the spring force of the spring 36 to actuate a microswitch 33. This causes actuating of an ink feed pump to feed ink to the ink kneading roller 26.

IPC: H01L21/033
Filed: 1980-01-09
Abstract: PURPOSE:To obtain the self-aligned level IGFET, by making use of the ion implantation and the anodization. CONSTITUTION:On the P type Si substrate 11 the Al film 12 is adhered and at the center of this part the mask 13 of SiO2 film is formed by the CVD method at the temperature of about 500 deg.C. In the substrate 11 on both side of the mask 13, the As or P ions are implanted to form the N type source and drain region 14. Next the mask 16 is formed by the same method on the part to be the electrode of these, and the O2 ions are implanted so that they reach the surface 17 being the interface of the film 12 and the substrate 11, to form the ion implantation region 18 around the region 14 where neither the mask 13 nor 16 exists. After annealing at the temperature of 400-500 deg.C the gate oxide film 17 of Al2O3 is formed in the region 14 and  after anodization the region 19 is formed in the film 12. Thus each electrode of the  gate, source and drain is separated by the region 19. After removing the mask 13  and 16 the level-surfaced FET is obtained.

Abstract: PROBLEM TO BE SOLVED: To enhance the presuming accuracy of the coke strength by measuring the expansion rate when the material is subjected to a dry distillation in a coke furnace wherein the measurement is performed in a condition near the coal environment. SOLUTION: By the method of presumption according to the present invention, the strength of the coke after dry distillation is presumed from the degree of coalification and caking of the coal to be put in a coke furnace, wherein the coke strength is determined from the expansion rate and the degree of coalification measured in such a condition that the thickness of the coal filled layer in a coal expansion rate measuring device is approx. equal to the thickness of the coal softened layer in the coke furnace. The thickness of the coal filled layer in the expansion rate measuring device is made between 5 and 15mm which is about the same as that of the coal softened layer in the coke furnace.

Filed: 1984-01-05
Abstract: PURPOSE:To detect air fuel ratio accurately from a rich region to a lean region by flowing a current to an oxygen pump in opposite directions between the rich region and lean region. CONSTITUTION:An air introducing plate 13 and a solid-state electrolyte 14 forms an air introducing part 28, and solid-state electrolyte 14 and 16 and a support 15 from an exhaust gas introducing part 29. Therefore, a sensor part 25 contacts the air at the side of its reference electrode 18 and also contacts exhaust gas at the side of its oxygen electrode 17 to generate electromotive force corresponding to the oxygen concentration of the exhaust gas. A pump part 26, on the other hand, flows the current in the solid-state electrolyte 16 from an anode electrode 21 to a cathode electrode as shown by an arrow IL when the current air fuel ratio as lean. Consequently, prescribed oxygen concentration is obtained at the exhaust gas introducing part 29. When the current air fuel ratio is rich, the current is flowed inthe opposite direction as shown by an arrow IR and the prescribed oygen concentration is held at the exhaust gas introducing part 29. The output of the sensor part 25 inthis state has abrupt variation at the air fuel ratio corresponding to the oxygen concentration at the exhaust gas introducing part 29.
