Title: Image contrast emphasizing method and image contrast processor
Inventor: ISHIKURA TADASHI
IPC: G06T5/00
Filed: 1999-02-03
Abstract: PROBLEM TO BE SOLVED: To provide a contrast-emphasized image by extracting the density value of an attentional pixel converted so as to increase the difference of gradation rather than the attentional pixel of an image. SOLUTION: A contrast processing circuit 16 compares the attentional pixel of a source image with a mean value, and when the density of the attentional pixel is close to the mean value and is white rather than a certain determined value, the level is changed by converting the pixel to white. Then, a maximum black value, a maximum white value, a mean value and the density value of the attentional pixel are detected from the information of respective pixels in a prescribed mask inside the image, the mean value is found from the information of density around or near the attentional pixel by a moving average method, and when the density of the attentional pixel is close to the mean value and the result of the mean value is close to white, the attentional pixel is changed into white pixel, but when the result of the mean value is close to black,  the attentional pixel is changed into black pixel. Next, when the gradation of respective pixels in the mask is remarkably dispersed, the difference of gradation is widened in the mask, density converting processing is performed and the density value of the attentional pixel, which is converted to enlarge the difference of gradation rather than the attentional pixel of the image, is extracted.

Title: Sine wave driving method for ac synchronous servo motor
Inventor: SAKIYAMA TAKASHI
IPC: H02P6/20
Filed: 1991-02-21
Abstract: PURPOSE:To perform sine wave driving of a servo motor immediately after turn ON of power by employing an intermediate value corresponding to the intermediate position of each section as an initial starting count immediately after turn ON of power at the time of starting drive control. CONSTITUTION:A and B pulses are fed from an encoder to a multiply-by-four circuit 1 where they are converted into up and down signals which are then fed to a counter 3. Three sets of phase pulses are fed from the encoder to an edge detecting circuit 2 which detects phase pulse edges and outputs a clear signal for clearing the counter 3 or a load signal for loading a maximum or intermediate count. A signal switch COS performs switching so that the transition command data for the counter 3 based on the load signal takes an intermediate value immediately after turn ON of power and then takes the maximum value.

Inventor: SEKIKAWA TOSHIHIRO
IPC: H01L29/786
Filed: 1990-02-06
Abstract: PURPOSE:To sharply enhance the characteristic and the reliability of an IGFET whose channel has been made short by a method wherein the length of an insulator layer formed at the lower part of a drain region is specified. CONSTITUTION:At an IGFET 10, an insulator layer 17 is formed between a drain region 14 and a semiconductor region 11. The insulator layer 17 is extended toward the side of a source region 13 from the junction part of the drain region 14 and a channel region 12; it is terminated at a position which does not reach the junction part of the source region 13 and the channel region 12. Since the insulator layer is situated between the drain region 14 and the semiconductor region 11, it is limited that a depletion layer which can be generated from the drain region 14 is extended to the semiconductor region. In addition, since a structure part sandwiched between a gate region 16 and the semiconductor region 11 via the insulator layer 17 exists, also a required shielding effect is given.

Title: File correcting system
Inventor: YASHIRO TAKEO
IPC: G06F1/30
Filed: 1981-02-27
Abstract: PURPOSE:To correct information to the reliable information, by storing a time of power failure and shifting the file information from the time of power failure to the time before time change, by the time difference between the time at change and before change, when the time of computer is changed through a CRT man- machine function with the stored time of power failure. CONSTITUTION:At power restoraton, a power failure processing 9 requests the restart of processing to a clock generating circuit 7 and stores the time of power failure stored in the circuit 7 to a power restoration time information 10. The command of change of the computer time is inputted to a processor 2 via a CRT man-machine device 1. A time change processing section 8 receiving this command requests the time change to the circuit 7 and also the file correction to a file correction processing section 15 via operation circuits 11 and 12. Thus, a processing section 15 shifts the file information from the time of power failure to the time change in a process information file group 14 by the time difference of the time change and corrects it into the reliable information.

Title: Sheet feeder
Inventor: NISHIMOTO YOSHIBUMI
IPC: H02N2/00
Filed: 1989-02-06
Abstract: PURPOSE:To make any sheet conveyable as well as to improve conveying force and efficiency at that time by installing an elastic body in which a part or all of the surface contacting with the sheet is roughed, and constituting a friction factor between the elastic body and the sheet so as to be larger. CONSTITUTION:Two elastic bodies 5, 6 are connected to a grounded circuit as an electric conductor, and frequency voltage is impressed on a vibrator 1 by a generator 7 whereby vibration is generated in these elastic bodies 5, 6. Vibrators 2, 4 generate power with the vibration, and when the electric energy is dissipated at an energy absorbing part 8, the vibration is not reflected and it comes to a progressive wave. When each bending vibration of these elastic bodies 5, 6 comes to the progressive wave, an outer part of bending has a velocity component in reverse to the forward direction of the progressive wave, feeding a sheet in reverse to the forward direction of the progressive wave. At this time, each surface of these elastic bodies 5, 6 is formed into a rough surface by means of honing or etching, etc., so that a friction factor between the elastic bodies 5, 6 and the sheet is increased, thus conveying force and its efficiency can be improved.

Title: Slurry mixture capable of protecting particle
Inventor: HONGU CHIU CHIEN
IPC: C10G47/26
Filed: 1989-02-06
Abstract: PURPOSE: To permit a fluid to transfer porous particles from a lower temperature place to a higher temperature place without damaging the particles by adapting the fluid so that it may have a critical temperature which is higher than that in the higher temperature place to which the particles are transferred and that it may have a critical pressure which is lower than the ambient pressure in the place to which the particles are transferred.  
     CONSTITUTION: In a slurry mixture used to transfer porous particles (e.g. catalyst particles) from the first place (e.g. catalyst storage tank) to the second place (e.g. hydrocracker or reformer) having a higher temperature, the mixture comprises a suspension of the porous particles in a carrier fluid, the critical temperature of the carrier fluid for the mixture is higher than the above high temperature, and the critical pressure of the fluid is lower than the ambient pressure of the second place. Thus, the fluid has the capability of protecting the porous particles to be transferred and therefore can carry the particles without causing their damage.

Abstract: PROBLEM TO BE SOLVED: To prevent the magnetic fault of an equipment due to the remanence of a floor face, presence of which is detected after the completion of a building. SOLUTION: A magnetic shielding layer 2 is formed into a space 14 in a double floor 1 consisting of a reinforced concrete slab 11 and a floor panel 12 supported onto the slab 11 in response to a magnetic-shield object region.

A demagnetizing field effective to the magnetic shield is formed even to remanence H in any direction by forming the magnetic shielding panel 21 in an undulating shape, thus leading out absorbed magnetism to a lower section from the outer circumferential section of the downwards directed magnetic shielding layer 2.
