IPC: H01L21/76
Filed: 1986-03-31
Abstract: PURPOSE:To prevent a latch-up phemonenon from occurring due to bipolar transistors parasitically formed by a method wherein a groove with an oxide film is formed between a diffusion layer of the first conductivity type MOS transistors and another different layer of the second conductivity type MOS transistors. CONSTITUTION:An oxide film 6, a non-oxidizable film 7 and a corrosion resistant film 8 are reduced by etching process from the boundary part of a well region 5 using a photoresist 9 etc. as a mask. After removing the photoresist 9, a substrate 2 is etched using the corrosion resistant film 8 as a mask to form an inverse mesa type groove10. Next, the groove 10 is thermal oxidized using the non-oxidizable film 7 as a mask to form an oxide film 12. At this time, the oxide film 12 is oxidized so that the depth thereof from the surface of substrate 2 may be sufficient to prevent a latch-up phenomenon from occurring. Finally, P channel NOS transistors 16 and N channel MOS transistors 17 are respcctively formed on the surfaces of N type epitaxial region 2 and P type well region 5 using the conventional technology.

IPC: C25D1/00
Filed: 1979-06-06
Abstract: PURPOSE: To form electrodeposition layer of uniform thickness by a method in which electrodes are set in a mutually facing manner at narrow intervals between the narrow small concavity or corner portion of an object to be processed and then electrification is made while vibrating any one of the electrodes and the interval is widened as the electrodeposition processing exceeds.  
     CONSTITUTION: The narrow small concavity is formed in the bottom 1b of a V-shaped surface to be processed by electrodeposition, for example, of the object 1 to be processed. The unnecessary portion of the small electorde 2 is coated with an insulating paint 2a.

While vertically vibrating the electrode 2 and also supplying a great amount of an electrodeposition liquid, electrification is made between the electrode 2 and the object 1 to be processed and as the processing exceeds, the elecrodeposition interval is widened by gradually moving back the electrode. Thus, electrodeposition can easily be performed on the portion where electrical shading is apt to occur, permitting uniform electrodeposition layer to be formed.

Title: Magnetic disk device
Inventor: ICHIHARA KATSUTARO
IPC: G11B5/012
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a cross erase and a cross talk even though the track pitch of a disk is made narrower by setting the angle between the direction perpendicular to the track direction and the magnetization transition line to be within a specific range on a disk surface and installing the magnetic disk in which the direction of the magnetization is practically made orthogonal with respect to the line. SOLUTION: Let θ be the angle between the direction perpendicular to a recording track direction and the magnetization transition line of the recording magnetic domain. Then, the inclination angle θ is set within the range of 25 deg. to 75 deg.. If the angle θ is less than 25 deg., the effect of improving the recording density is not significant by narrowing the width of a guard band. If the angle θis set to 25 deg., which is the lower limit value, the equation cosθ=0.91 is estarished, an approximately 10% reduction is realized for the width of the guard band and as a result, an approximately 10% improvement is achieved in the recording density. On the other hand, if the angle θ is made larger than 75 deg., the transition noise becomes significant. Thus, it is desirable to set the angle θ to be <=75 deg. to avoid the excessive increase in the transition noise.

Title: Image forming method and device therefor
Inventor: SHIOBARA SUSUMU
IPC: B41J29/38
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To avoid the occurrence of an image forming error by starting an avoiding processing executed instead of an image forming processing when the error occurs in the first place on a job whenever an evaluation value based on the content and quantity of data being a conversion object is deviated from a prescribed setting value. SOLUTION: At the time of forming an image based on printing data inputted in a job unit by a printer device 1, a controller 2 to which a function as an error detection part is added detects the occurrence of the image forming error on the job and forms the image based on the evaluation values of the content and quantity of data being the conversion object. Namely, the avoiding processing of the image forming error is started when a situation where the image forming error occurs is generated in a process for forming the image. Thus, the occurrence of the image forming error can surely be prevented and the deterioration in throughput can be suppressed to a necessary minimum.

Filed: 1985-04-05
Abstract: PURPOSE:To prevent drop in processing ability by dividing a memory device into plural banks, and providing a bus exclusively used for a processor and a circuit controlling access competition from a common bus at every bank. CONSTITUTION:The memory device 5-1 of a processor 3 is divided into three banks 12-14, which are connected to a competition control circuit (9-11). When the processor 3 indicates a processor 2 to transfer data in an external memory device 1 to an address allocated to the bank 12, the processor 2 transfers the data to the bank 12. On the other hand, when the processor 3 reads an instruction out of the bank 12 and executes such a program as writing data in the bank 14, processing can be executed without competing the data transfer action of the processor 2.

IPC: G01P3/80
Filed: 1990-03-22
Abstract: PURPOSE:To shorten an operational processing time, to enhance resolving power and also to enhance speed detection accuracy by narrowing or widening an operation range calculating real time lag quantity in the stable or unstable state of the moving speed of an object to be inspected. CONSTITUTION:The rough moving speed of a web 1 is detected on the basis of the speed signal from the pulse generator 8 connected to the touch roll 7 rotating so as to follow the web 1. On the basis of a change in the rough moving speed, it is judged whether speed is stable or unstable. In the speed unstable state, by setting the number of samplings being 1024 heretofore to 100, an operational processing time can be reduced to about 1/10. When the moving speed is stable, the sampling collecting and operating range of the light detection signals from respective light detection sensors 4A, 4B is set, for example, to + or -3% of real time lag quantity to set the number of samplings to 100 in the same manner. By this method, resolving power can be enhanced.

The obtained logarithmic image is binarized according to the Laplacian arithmetic processing result obtained for every RGB of each pixel, and the line thinning processing is applied to the binalized image. In this case, the CPU expresses a natural spline function corresponding to a sequence of points of the binalized image as a parametric function of each of coordinates defining a space from the positional information, i.e., the coordinates of each point of the sequence of points.  Then the CPU generates a B-spline curve K1, i.e., a smoothed approximate curve of a sequence of points according to the parametric natural spline function obtained for each of coordinates.
