Filed: 1999-07-29
Abstract: PROBLEM TO BE SOLVED: To improve the quality of an image even at the time of monotone conversion by finding the distribution of luminance equivalent values by each pixel and generating a monotone image having its pixels converted in luminance according to the correspondence relation of luminance conversion. SOLUTION: An image acquiring means A1 acquires image data having data on gradation values by element colors. According to the image data, the image acquiring means A1 easily calculates the luminance equivalent values (y) and makes a luminance distribution totalizing means A2 to totalize the values, and the luminance distribution totalizing means A2 totalizes a frequency distribution DB of the luminance equivalent values. A luminance correspondence relation setting means A3 sets the correspondence relation of luminance so that an optimum image can be obtained when represented monotonously according to the frequency distribution DB.  An image data converting means A4 obtains a luminance equivalent (y) according to the source image data RGB or refers to LUT4R, LUT4G, and LUT4B according to the luminance equivalent (y) calculated by the image acquiring means A1 and outputs the reference results as converted image data R', G', and B'.

Abstract: PURPOSE:To suppress variation of sintered body characteristics due to difference in production method, alumina material, and sintering conditions easily and without causing any problem on handling of material, toxicity, and characteristics, industrially by specifying the composition of beta alumina. CONSTITUTION:The mole ratio of Al2O3/Na2O on aluminum oxide, sodium oxide, and lithium oxide that are the oxides to form beta alumina is set at 6 to 7.

By specifying the composition of the beta alumina like this, an electrolyte with microstructure of which conductivity is not lowered and grains are not grown is obtained. Therefore the durability of a battery can be increased without reducing the output of the battery. Also, becuase the production conditions or sintering conditions affect less on the characteristics, the characteristics do not vary even if a slight difference is produced in the sintering temperature or sintering time, and thus a product stable in quality in industrial production can be provided.

Title: Ultrasonic wave transmission circuit and ultrasonic wave measuring instrument
Inventor: HYODO SHIGETOSHI
IPC: G01N29/07
Filed: 1993-08-31
Abstract: PURPOSE:To perform high-resolution measurement with high sensitivity and a high S/N by outputting a transmission pulse having a pulse width wider than the vibrating period of an ultrasonic vibrator or than the period of a received frequency by an integer multiple to the ultrasonic vibrator. CONSTITUTION:A transmission circuit 11 generates a square-wave pulse having a pulse width wider than the center frequency period of a receiving amplifier circuit 13 by an integer multiple and excites an ultrasonic vibrator in a wide-band frequency probe 12 by impressing the pulse upon the vibrator. The excitation of the vibrator is performed at both the trailing edge and leading edge of the pulse. As a result, ultrasonic waves are generated and made incident to a material 4 to be measured. The ultrasonic waves made incident to the material 4 are reflected at a flaw, base of the material 4, etc., and reflected echoes are received by means of the probe 12. Received signals are inputted to a measurement circuit 14 after they are amplified at the amplifier circuit 13. When the signals are inputted to the circuit 14, the number of vibration of the signals is reduced, because the amplitude of the corresponding signal part after the leading edge of the transmitted pulse is offset by synthesization and interference. Therefore, a high-resolution waveform having a less number of vibration can be obtained.

Title: Structure of dielectric resonator filter
Inventor: ISHIZAKI MASAYUKI
IPC: H01P1/04
Filed: 1989-08-23
Abstract: PURPOSE:To make the length in a filter in its connection direction constant by varying the length of standard waveguide flanges corresponding to the hand width of the filter and making the length of the filter in the connection direction constant irrelevantly to the hand width. CONSTITUTION:When the band width is narrow, the interval between adjacent dielectric resonators is wide and the waveguide type dielectric resonator filter 51 becomes long correspondingly, so standard waveguide flanges 51 and 61 are shortened in length L1. When the band width is wide, on the other hand, the interval between the adjacent dielectric resonators 4 becomes narrow and the waveguide dielectric resonator filter 31 becomes short, so the standard waveguide flanges 51 and 61 are made long in length L1. Consequently, the connection-directional length L of the waveguide type dielectric resonator filter with the input/output waveguide flanges can be held constant irrelevantly to the band width.
