Title: Color converting device
Inventor: MATSUZAKI TOMOYASU
IPC: H04N1/46
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To respectively convert the plural optional colors of an optional color space coordinate system into other colors in the same color space without burdening a hardware and without generating noncontinuity with the color out of an object. SOLUTION: The plural center colors Ci1 and Ci2 are designated as the center colors before conversion. The plural conversion ranges S1 and S2 are respectively designated as distances from the center colors Ci1 and Ci2. The plural center colors Co1 and Co2 are designated as the center colors after conversion. The relative distances D1 and D2 of the center colors Ci1 and Ci2 before conversion with an input color Pi are calculated and the smallest one is outputted as the relative distance Dm which does not exceed one. The relative distance Dm is converted into a weighing coefficient.  The weighing coefficient is multiplied by a difference corresponding to the smallest of the relative distances D1 and D2 between the differences d1 and d2 between the center colors Co1 and Co2 after conversion and the center color Ci1 and Ci2 before conversion and then the multiplication result is added to the input color Pi.

Title: Combustion control of coal fired stoker boiler
Inventor: FUKUMOTO KATSUTOSHI
IPC: F23N5/00
Filed: 1983-03-09
Abstract: PURPOSE:To make various properties of a load side plant easily controllable by a method wherein the feeding state of coal lumps is monitored and the action to increase the output of a controller is prevented during the period, in which the generation of abnormality contitunes. CONSTITUTION:A judging device 51 receives a signal from an ammeter 50 and a signal inputted to a stoker drive 3 and compares them with each other. If the current lowers and no current corresponding to said signal inputted to the stoker drive 3 is received by the judging device 51, the device 51 decides the generation of abnormality of the feeding state of coal and consequently changes-over the mode of a controller 12 from a proportional plus integral control action to a proportional control action. The controller 12 performs the control action, before an abnormality decision signal arrives, by a proportional plus integral control action and, after the abnormality decision signal is inputted, the control is performed by a proportional control action only because an integral control action is held by the abnormality decision signal. Accordingly, the signal inputted to the stoker drive 3 does not largely differ from the value before the generation of abnormality of feeding state. Thus, various properties of a load side plant are made easily controllable.

IPC: G11B20/20
Filed: 1988-02-22
Abstract: PURPOSE:To easily detect and correct skew quantity by counting a time to regenerate a synchronizing signal or an identification signal from a recording medium and comparing the time with reference time. CONSTITUTION:A video to be recorded by video heads 3, 4-6 of a rotary drum 2 is taken out in order by a video head switching circuit 29 and conducted through ID signal detecting circuits 30 and 31 and a synchronizing signal detecting circuit 32 to a gate generating circuit 38. When a gate signal phi9 of the circuit 38 is 'H', a clock phi10 of a frequency divider 28 is counted by a programmable counter 40. A time length t2 between counted synchronizing signals S2 and Sm at the time of regenerating is fetched into a RAM 23 and a time length t1 between the computed signals S2 and Sm is integrated to a ROM 24. Then, a program is included to calculate a differential time DELTAt1=t1-t2. On the other hand, a CPU 22 executes the program of the ROM 24 and calculates the skew quantity error DELTAt1 and tension to obtain DELTAt1=0 is calculated from the program of the ROM 24. Then, tension setting 42 is executed and the skew quantity is detected and corrected.

Title: Magnetic recording medium
Inventor: HORIE KIYOSHI
IPC: G11B5/80
Filed: 1990-02-19
Abstract: PURPOSE:To enable writing with various kinds of magnetic heads and to prevent theft or forging of data by using at least two kinds of magnetic particles having different particle sizes to form a magnetic layer on a substrate surface. CONSTITUTION:The magnetic layer 2 consists of a mixture of magnetic particles 21 of large particle size and magnetic particles 22 of small particle size. When a magnetic head (A) having a gap width suitable for the magnetic particles 21 is used to apply a magnetic field on this layer, both of particles 21 and 22 are magnetized. On the other hand, when a magnetic head (B) having a gap width suitable for the magnetic particles 22 is used, only the magnetic particles 22 are magnetized while the magnetic particles 21 are not magnetized. Therefore, two kinds of different data can be written in one magnetic layer 2 and the recorded data can not be written in one magnetic layer 2 and the recorded data can not be completely read out without reparing all of the magnetic heads applicable for respective magnetic particles. This prevents theft or forging of the data.

CONSTITUTION:The light from a laser beam source 1 is divided to optical paths A and B in a splitter 3 through a return light eliminating means 10, the first condenser lens 21, and the second condenser lens 23. The light in the optical path A has the optical path length changed minutely by a wedge glass 41 and is returned through the optical path A by a reflective mirror 45. The light in the optical path B is irradiated to a material to be measured such as a convex mirror and is returned through the optical path B. In an optical path C, the interference between lights of optical paths A and B is detected on an image pickup face 73 to detect a two-demensional phase distribution of the measuring face. Directions of the reflective mirror 45 and a face 6 to be measured are detected by a position detector 221, and lights of optical paths A and B are controlled to return to an aperture 24 of a stop 22. Since reflection lights due to light-permissive materials in optical paths become a noise, they are eliminated by a light shielding plate 72 with an aperture.

Abstract: PURPOSE:To facilitate production and to enhance the propagation efficiency of a light beam by curing a UV curing resin to form core parts and forming a clad part of a methyl pentene polymer. CONSTITUTION:The methyl pentene polymer having 1.463 refractive inden is injection-molded into a mold to form the flat plate clad part 11 formed with many groove parts 11a at a prescribed pitch on one surface. Acrylate which is a UV curing resin having about 1.53 to 1.57 refractive index is packed as a core material into the groove parts 11a to form the core parts 12. Since the packed core material is the acrylate of a low viscosity, the packing is easy and the packing at and under ordinary temp. and atm. pressure is possible. The core material is then cured by irradiation with UV rays from a UV ray source to form the core parts 12. The clad part 11 and the core parts 12 are coated by the UV curing resin by using a method for coating, such as spraying, to form the clad part 13. The optical waveguide array 10 is thus formed.

After the simplified heating element 4 is inserted and fitted through the opening section 13 of the storage section 12, a foot can be inserted to wear a boot main body. The simplified heating element 4 is fixed together with the storage section 12, it is not drifted, it is located on the outside of an inner boot 1, and a sense of incompatibility is rarely felt.  When the heating element 4 is to be replaced after the heating/heat retaining time elapses, the opening section 13 is cut into a nearly U-shape, then the heating element 4 can be picked out with the finger tips of gloves.
