Title: High efficient encoder of television signal
Inventor: KONDO TETSUJIRO
IPC: H04N19/50
Filed: 1985-10-18
Abstract: PURPOSE:To improve a compression rate by obtaining a dynamic range (difference between maximum level and minimum level) and the minimum level with respect to plural picture elements and using the compressed quantized bit number so as to divide the dynamic range thereby encoding each picture element in a block to a code having the nearest level. CONSTITUTION:A dynamic range DR detected by a dynamic range calculation circuit 3 is fed to a quantization width (DELTA) deciding circuit 5, which divides the dynamic range DR in a step number corresponding to the quantization bit number to calculate a 4-bit quantization width DELTA and generates an 8-bit representative minimum level L0. A picture element data DT 1 after the quantized width DELTA and the minimum level are eliminated is fed to a quantization circuit 6. The quantization circuit 6 discriminates in which region divided the picture element data DT 1 after the minimum level is eliminated and generates the coded code DT in 4-bit specifying the region. one block 9 being the unit of coding consists of two-dimension regions 9A, 9B, 9C and 9D belonging to each field of two frames (4-field).

Inventor: KASAMA ICHIRO
IPC: G01N21/01
Filed: 1994-09-28
Abstract: PURPOSE: To require no complex control by heating a blackbody panel up to a specified temperature so as to make a specified band of wavelength components of a radiated infrared ray transmit. CONSTITUTION: An infrared ray transmitting glass 2 is fitted on the front face of a box case 1 made of stainless, an infrared ray transmitting glass 3, a blackbody panel 4 for infrared ray radiation, and an electrical heater 5 are fitted thereafter, and the periphery of the panel 4 and the heater 5 and surrounded by adiabatic material 6 so as to constitute an infrared ray radiation panel assembly. The infrared ray transmitting glasses 2, 3 constitute the 3.3mm band infrared ray radiation panel assembly. When the heater 5 is energized so as to heat the panel 4 up to 440 through 450K (about 170 deg.C), only about 3.0 through 3.8μm components out of radiated ray from the panel 4 transmit the glass 3. Next, only about 3.0 through 3.6μm wavelength components transmit the glass 2, and other wavelength components are sharply cut off.  The 3.3μm band infrared ray has quite a large absorption coefficient against a CH radical, and can be used for detecting hydrocarbon gas containing the CH group.

Title: Character processor
Inventor: SUGITANI KAZUNOBU
IPC: G06F3/02
Filed: 1985-10-17
Abstract: PURPOSE:To eliminate a complicated operation for proper use of parentheses with a character processor containing a document memory for input characters and parentheses, by securing the coincidence of numbers between the right and left parentheses. CONSTITUTION:An input key is discriminated and a parenthesis counter KCO is discriminated when a character key is operated. Then the character codes are stored in a document memory BSM when the counter KCO is equal to '0'. When a parenthesis key is operated, it is checked whether or not the right parentheses are supplied in the same number as the left parentheses. Thus a character flag MFL is cleared to '0' when the counter KCO is equal to '0'. While the left parentheses are continuous when the flag MFL is equal to '0', the left parentheses are stored in the memory BSM corresponding to a cursor position memory CRLM.

Title: Apparatus for automatically adjusting uniformity of static magnetic field for mri magnet
Inventor: MATSUDA TETSUYA
IPC: G01R33/38
Filed: 1984-11-07
Abstract: PURPOSE:To make it possible to accurately perform the automatic adjustment of the uniformity of a static magnetic field, by using a means for calculating the area of a NMR signal and valuating the uniformity of the static magnetic field from the reciprocal of said area. CONSTITUTION:If a FID signal is integrated from t=0-t=infinity  (the integrated result is set as a FID area) and the reciprocal of the integrated value is calcu lated, formula I [wherein A(t) is the FID area] is obtained. Therefore, the reciprocal of the FID area is equal to 1/T2 and proportional to the uniformity of a static magnetic field. If the current value of a correction coil is regulated so as to make the reciprocal of the FID area min., the uniformity of the static field can be optimized. If a spin echo signal is integrated from t=<->infinity  to t=<+>infinity  (the integrated result is set as a spin echo area and a NMR signal area is a general term for both of the FID area and the spin echo area), formula II [wherein A (t) is the spin echo area] is obtained. Therefore, if T2 is calculated, the uniformity of the static magnetic field can be evaluated from the reciprocal of the spin echo signal in the same way as the FID area.

Abstract: PURPOSE:To reduce surface flaw and to improve the quality of a cast slab by setting a static magnetic field impressing device in a mold, making the specific value or lower of magnetic flux density on molten steel surface in a mold and further, making the specific value or lower of the max. magnetic flux density at unsolidified part of molten steel in a strand in the mold or just below the mold. CONSTITUTION:To the cast slab in the mold 1 and/or at neighborhood of just below the mold, static magnetic field 8 is impressed with a static magnetic impressing device 3 and continuous casting is executed. The above static magnetic field impressing device is set to the mold and the magnetic flux density on the molten surface in the mold, i.e., at the meniscus, is made to <=0.04T (tesla). The max. magnetic flux density at the unsolidified part of the molten steel in the strand in the mold or just below the mold is made to >=0.16T. At the time of using the static magnetic field impressing device 3, by non-magnetic body 10, in which the magnetic flux is difficult to pass through, the magnetic flux density near this is reduced and the magnetic flux density at the meniscus and the max. magnetic density can be set to <=0.04T and >=0.16T, respectively. By this method, while drastically reducing the surface flow of longitudinal crack, pinhole, etc., the inclusion is reduced and the quality of cast slab can be improved.

Filed: 1991-08-22
Abstract: PURPOSE: To provide a method for efficiently and accurately assembling an electronic system, by utilizing a robotics technology. CONSTITUTION: This invention is characterized in the application to the automatic bonding of electronic components to a circuit board 30. A layout/bonding heat 28 is mounted on an operable robot arm 20, and utilized to select electronic components having leads from electronic components feed sources and to position the components adjacent to contact pads on the circuit board. The components are held in the layout/bonding head and bonded thermally to the contact pads. Thus, without multiplying operation of the electronic components, they are gripped, tested, accurately positioned at desired regions on the circuit board and bonded thereto. The dispersion of thermal loads exerted on blades, which would cause the bonding error, is effectively eliminated.
