IPC: G03G5/16
Filed: 1983-09-07
Abstract: PURPOSE:To obtain the more uniform reproducibility of a solid and a dot image by impressing dot-shaped heat input such as thermal head and laser light so that they overlap each other spatially on a magnetic latent image carrier, and making an external impressed magnetic field opposite in direction synchronously. CONSTITUTION:The magnetic latent image carrier moves as shown by an arrow 8 to draw a track shown by a chain line 9. Simultaneously, an external magnetic field 7 is impressed firstly and then an external magnetic field 7' in the opposite direction is impressed; and the direction of the external magnetic field is inverted repeatedly to form magnetic latent images 5a, 5b... on the magnetic latent image carrier in alternate directions. An integral multiple of the length of magnetism produced in one heat cycle is one magnetic latent image unit, which is formed to an optional multiple of magnetism length. The solid image, therefore, consists of magnetic latent image units having a sufficiently large multiple of magnetisum length, and a magnetic field which has the magnetism length as basic repetition in free space is established in the solid, so the uniform sticking of magnetic toner and magnetic ink is possible.

Title: Manufacture of thin-film solar cell
Inventor: FUJIKAKE SHINJI
IPC: H01L31/04
Filed: 1990-06-21
Abstract: PURPOSE:To obtain a sufficient open-circuit voltage by means of a thin microcrystalline p-layer and to increase a short-circuit current by a method wherein, after the surface of the p-layer has been plasma-doped with acceptors, an interface layer is laminated. CONSTITUTION:A microcrystalline silicon p-layer 3 is formed on a transparent electrode 2 on a glass substrate. Then, when a plasma-doping operation is executed, a plasma-doping layer 8 is produced. In succession, an a-SiC interface layer 4 is formed. In addition, an i-layer 5 and an n-layer 6 are formed. Lastly, a rear electrode 7 is formed. In this case, the surface of the layer 3 is plasma- doped with acceptors, and the layer 4 is laminated on it. Then, the acceptors are diffused to the layer 4 during the formation process of the layer 4, and the good-quality p-layer which does not contain any impurities is formed. Accordingly, even when the layer 3 is thin, it is possible to obtain a sufficient diffusion potential between it and the layer 5. As a result, a sufficient open circuit voltage value is obtained. Since the layer 3 is thin, a short circuit current is increased. Since also a curve factor is high, a high conversion efficiency can be obtained.

Title: Ecl latch circuit
Inventor: HATA IKURO
IPC: H03K19/086
Filed: 1999-06-10
Abstract: PROBLEM TO BE SOLVED: To enlarge a noise margin by providing an additional current source circuit for normally flowing a current to a latch part in addition to a constant current source. SOLUTION: An additional current source circuit S1 connected to an emitter side of a transistor Q4 on a latch circuit side consists of, for example, a current mirror circuit and constantly flows a current Iadd of several to 10 percent of its operation current Io to transistors Q3 and Q4. Since the current constantly flows to the transistors Q3, Q4 or the like which constitute the latch part from the additional current source circuit S1, the transistors Q3 and Q4 of the latch part are not completely turned off even switched and a distortion of an output waveform is not caused.  In this case, actually the transistors Q3 and Q4 are virtually not turned off because the transistors enter a latch operation state earlier than they are turned on from the state in which they are turned off in accordance with an amount of the additional current, and the distortion of the output waveform is reduced.

Filed: 1994-07-15
Abstract: PURPOSE:To discriminate new rice from old rice, and estimate taste value close to the actual taste value by correcting a derived taste value according to smell information detected from a sample rice. CONSTITUTION:Sample rice S is thrown into a sample rice throwing-in hopper 32, and when an opening closing cover 33 is closed, a smell sensor 34 arranged on an inside wall of the cover 33 operates, and detects a smell information. At the same time, the sample rice S is housed in a vessel 8, and a taste value deriving means derives an estimated taste value by a spectral analysis formula. That is, a measuring light beam bundle is cast on the sample rice S, and a transmitted light beam bundle is separated into its spectral components. An absorbance spectrum of the sample rice S is obtained from detecting information obtained by receiving the spectral light beam bundle. A taste value of the sample rice S is derived from this absorbance spectrum. A derived estimated taste value is corrected according to the smell information, and a corrected estimated taste value by considering optical factor and smell factor is obtained. Therefore, new rice can be discriminated from old rice, and taste value based on the actual condition can be estimated.

Patent JP-H11353616-A (JP)
Title: Thin-film magnetic head and its production
Inventor: SASAKI YOSHITAKA
IPC: G11B5/31
Filed: 1998-06-11
Abstract: PROBLEM TO BE SOLVED: To enable the extremely fine processing of the submicron sizes of not only the magnetic pole front end of bisected upper electrodes but the upper magnetic pole layer as well. SOLUTION: The upper magnetic pole is bisected to the magnetic pole front end 20 and the upper magnetic pole layer 25. The magnetic pole front end 20 is formed via a recording gap layer 19 on the plane surface on the lower magnetic pole 18. As a result, the magnetic pole front end regulating a recording track width is processed to the submicron size. An insulating layer 21a is formed in a region adjacent to the magnetic pole front end 20. A first layer of a thin- film coil 22 is formed within the region where the insulating layer 21a is formed. The thin-film coil 22 is covered by the insulating layer 21b flattened on the surface. As a result, the difference in level of the apex part inclusive of the thin-film coil 23 is made lower than the conventional structure by as much as the thin-film coil 22.  Then, the influence of the difference in level of the apex part is reduced at the time of forming the upper magnetic pole layer 25 by photolithography and eventually the submicron size of the upper magnetic pole layer 25 may be made finer.

Filed: 1978-12-28
Abstract: PURPOSE:To increase the reception sensitivity by securing a larger cross-sectional area at the edge part of the ferrite antenna than the center part and thus giving the induction of a high-level voltage to the antenna coil.
