Title: Data binarization method
Inventor: SUZAKI HIRONORI
IPC: H04N1/403
Filed: 1991-06-10
Abstract: PURPOSE:To prevent the occurrence of noise of a large area by binarizing so that distributed black points are made to a black level and other are made to a white level also for the background only section. CONSTITUTION:When a background is a white level and a character to be an object is a black level, for instance, the points of the black level (the blackiest level) are distributed almost equally in data. Subsequently, the data for binarization is divided into plural sections and is binarized in every section. As a substitution point of maximum value or minimum value reverse to the background exists in each section, the substitution port is binarized as an object in the section where the object does not exist. Therefore, when such picture data is binarized, sections D00, D01, D30 to D33 becomes a binarized picture which black points (substitution points) exist on a white ground. Finally, the substitution points are absorbed in the background and be extinguished as this binarized data is smoothened.

Title: Manufacture of inductance element
Inventor: SAKAKURA MITSUO
IPC: H01F41/04
Filed: 1982-08-10
Abstract: PURPOSE:To obtain the small-sized inductance element of high Q by forming a conductive layer in sufficient thickness and reducing resistance. CONSTITUTION:Ferrite 24 is printed on a ferrite layer 21 by using a mask 22 except the section where a conductive layer is formed. The conductive layer 23 is printed by using a mask 25. The mask 25 is formed in a pattern reverse to the mask 22. Conductive paste is printed to the section surrounded by the ferrite 24 and the upper section of said section. The conductive layer is formed, and ferrite 26 is printed on the conductive layer 25 and the ferrite 24. The process is repeated in succession, these layer and ferrite are laminated until the number of the conductive layers wound reaches a fixed number, and the whole is baked. Since the conductive layers are printed thickly at that time, sufficient thickness is kept even when they are shrunk through sintering. According to the manufacture, the thickness of the electrode of the element can be taken in a sufficiently large value. Consequently, the resistance of the electrode can be reduced, and high Q can be obtained.

Abstract: PURPOSE:To obtain a small-sized optical head having a short time lag at the time of an overwriting of the like by installing objective lenses, which converge light on different positions on an information recording medium respectively, on a lens holder. CONSTITUTION:The holder 2 is controlled in a focus direction A by electrifying a coil 5, and the optical head is controlled in a track direction B by electrifying the coils 12a, 12b. In a case that the overwriting is given to the track, traveling forward in an arrow mark direction C, a permanent magnet 29a is arranged in an area, magnetized vertically so as to turn an upper side into N pole, and in the direction so as to invert a magnetization direction. A light beam 9a is converged on the track 26b by the objective lens 1a, and a coercive force is lowered by a temperature rise and eliminated by an interaction between the magnetic flux 30a of the magnet 29a. Besides, by arranging the permanent magnet 29b in the contrary direction against the 29a, and inverting the magnetization direction similarly to the case of the elimination, a recording is performed. In this constitution, the objective lenses can be arranged closely to each other, and the optical head device, which is small-sized and has the short time lag, can be obtained.

Title: Fuel injection timing control method for multi-cylinder internal-combustion engine
Inventor: MATSUDA YOSHIHIKO
IPC: F02D41/34
Filed: 1983-07-28
Abstract: PURPOSE:To control fuel timing injection with little variations in responsibility as compared with other angle states even at any crank angle by injecting a fuel at every rotation of a prescribed angle from a crank shaft angle when the change of a load is judged to be over a prescribed value. CONSTITUTION:Upon controlling fuel injection timing by an electronic control circuit 20, if the amount of change R of a throttle opening is over a prescribed value (a) due to rapid acceleration, alpha crank angle +gamma at the time of judgement is set. Then, when a crank angle alpha reaches an injection angle, the fuel is immediately injected, and when the angle a is not the injection angle and the angle alpha reaches the crank angle beta, the value of the angle beta is set to the injection angle, allowing the fuel to be injected. In addition, when gamma is not 0, or a value exceeding 0, a relation alpha=beta is not obtained since beta is set to the value of the crank angle +gamma at this time. However, during the repetition of said treatments, alpha agrees with the value of the crank angle +gamma when a relation R>=a is attained, thus allowing the fuel to be injected. Hereby, the responsibility is increased since a crank is merely rotated by 120 deg. till the first ignition timing as the fuel is increased.

Abstract: PURPOSE:To provide a copying device in which a failure that the copied sheets of an identical original are distributed to be superposed on an identical pin is prevented in the case that copying is continued in a sorting mode. CONSTITUTION:When a series of copying actions is finished (YES at a step S22) and sorting is selected (YES at a step S23), the next copying actions are started without opening or closing the original cover (NO at a step S24, the original is not exchanged). At such a time, an ejecting pin for specifying the pin being the distributed destination of the copied sheet is not set to '1' processing at step S26 is not performed). Therefore, as to the copying actions which are started without exchanging the original, the copied sheet is distributed from the pin at the next stage to the pin used for the distribution of the copied sheet by the copying action just before.
