Filed: 1991-03-18
Abstract: PURPOSE:To provide the wide-band optical modulating element which has neither a decrease in characteristic impedance nor an increase in the propagation loss of a microwave and no rise in driving voltage and completely matches the speeds of the microwave and light with each other. CONSTITUTION:A substrate part is so structured as to have a projection by etching and digging part of a substrate 1 in an area where the intensity of a microwave electric field propagated in a traveling signal electrode is intense; and the thickness of the traveling wave electrode, the depth of the etching, and the thickness of a buffer layer are properly determined so that the effective refractive index of the microwave propagated in the traveling wave electrode approximates the effective refractive index of light propagated in a light guide 2 and the characteristic impedance of the traveling wave electrode approximates the characteristic impedance of an external circuit. When this optical modulating element constituted as mentioned above is equipped with a shield conductor, the thickness of its overlay is considered for said determination. Further, the buffer layer at the etched part is preferably hollowed.

IPC: F27D99/00
Filed: 1984-03-19
Abstract: PURPOSE:To seal thoroughly a converter port and skirt by breaking the slag sticking to the port by a water-cooled sealing ring provided in the lower part of the skirt and sealing the leaking gas by the chain screen-like sealing ring provided on the outside thereof. CONSTITUTION:The 1st sealing ring 17 made of a heat resisting cast iron having a circular section is first brought into press contact with a converter port 12 by a cylinder 21 for a skirt and the slag of a high temp. sticking to the port 12 is quickly cooled by the cooling water flowing in the hollow part 17'. The slat is broken by the thermal impact effected from said quick cooling and is crushed by the pressing force, by which the port 12 and the ring 17 are held in nearly the hermetic state. The chain screen-like 2nd sealing ring 18 contacts with the port 12 corresponding to thermal deformation or manufacturing error of the port 12 and forms the chain screen around the ring 17, thereby sealing the leaking gas.

Title: Composition and method for preventing adsorption of secretin
Inventor: KAKIMOTO FUMIO
IPC: A61K38/22
Filed: 1981-04-10
Abstract: PURPOSE: To prevent the adsorption of secretin to the glass wall, and to reduce the adsorption loss of secretin, by adding a basic amino acid to the composition containing secretin.  
     CONSTITUTION: A basic amino acid (e.g. arginine, lysine, ornithine, histidine, etc.) having an isoelectric point of ≥7 or a mixture of said amino acid is added to a secretin-containing composition. The composition is an aqueous solution, freeze- dried powder, or a combination of freeze-dried powder and aqueous solution. The amount of the basic amino acid is preferably 0.1W10% of the secretin-containing solution. Secretin is a pancreatic juice secretin hormone, and used in the remedy or diagnosis of various pancreatic and gallbladder diseases. Since the amount of administration is very small, secretion is liable to be adsorbed to the glass ware to cause a considerable amount of loss. The addition of the basic amino acid enables the desorption of the secretin from the glass wall to the aqueous solution.

Title: Bucket type ion source apparatus
Inventor: TAWARA HIDEAKI
IPC: H01J27/14
Filed: 1994-03-24
Abstract: PURPOSE:To suppress the temperature rise of a magnet without enlarging a bucket type ion source apparatus and making the apparatus complex by putting a heat insulating material between the magnet installed along the wall of a plasma chamber and the wall of the plasma chamber and generating a cusp magnetic field. CONSTITUTION:A heat insulating part 9 is sandwiched by a permanent magnet 2 and a plasma chamber 1 to suppress the temperature rise of the magnet 2 and no cooling tube is provided. Calcium silicate is used as the material of the heat insulating part 9 and a stainless steel is used as the material for the plasma chamber 1. The heat insulating part 9 is put between the chamber wall of the plasma chamber 1 and the permanent magnet 2 set along the chamber wall to generate a cusp magnetic field. Consequently, heat generated following plasma P production in the plasma chamber 1 is suppressed from being transmitted to the permanent magnet through a region B2 and deterioration due to the temperature rise of the permanent magnet 22 is prevented. By putting the heat insulating part 9, the structure of other parts of the apparatus is not restricted by a cooling tube and thus there is no need of enlarging the apparatus or making the apparatus complex.

Filed: 1981-04-07
Abstract: PURPOSE:To ensure the working of an antenna with a small structure and in two different frequency bands, by using an outer frame of a horn type antenna as a monopole antenna. CONSTITUTION:The outer frame of a horn type antenna waveguide 7 constitutes a coaxial inner conductor 2, and the outer frame of a horn type antenna aperture part 6 forms a cone type antenna radiation element 1. The electromagnetic wave fed to a feed part 4 of the cone type antenna is transmitted to a coaxial line formed with the conductor 2 and a coaxial outer conductor 3 via a branching coaxial line 9 to be radiated through a cone type antenna consisting of a cone type antenna radiation element 1 and a ground plate 8. While the electromangnetic wave fed to a horn type antenna feed part 5 is radiated through the part 6 via the waveguide 7. The frequency band of the cone type antenna is usually set at 25MHz-1GHz, and the horn type antenna is set at 1GHz-100GHz respectively. Thus an antenna which works with different frequencies can be formed with a unified antenna of a small size.

Abstract: PURPOSE:To surely execute the correction of a signal by providing a control means for executing control so that after a correcting signal has been supplied once to an inverting means, the inverting means is not operated by the correcting signal at least in a period to the rear end of the next horizontal synchronizing pulse. CONSTITUTION:An output pulse from an AND circuit 12 and an output pulse from a flip-flop circuit 21 are supplied to an OR circuit 15. Subsequently, when an inversion output of the signal is supplied to an AND circuit 18, a correcting pulse is supplied from a terminal 19 and inputted, thereafter, in a period of about 2H, a gate to the correcting pulse is executed. Also, even if the correcting pulse is supplied from the terminal 19 in this period, no pulse is outputted from the flip-flop circuit 21. That is, after the correcting pulse has been supplied once to this circuit, even if the correcting pulse is supplied in the period of about 2H, this pulse becomes ineffective, an inverting operation of a switching control signal is not executed, and a switching state of a reference subcarrier wave is not inverted.

Abstract: PURPOSE:To improve the separating accuracy of a dot photograph and a character in a document image. CONSTITUTION:An input image read by an input device is binarized by a binarizing part 2. A run length calculating part 3 calculates a run length as the length of continued black picture elements in the binarized image. A run expanding part 4 executes expanding processing with the black picture elements of the binarized image as objects. A maximum run length calculating part 5 calculates the maximum value of the run lengths of black picture elements within a range corresponding to the part of continued black picture elements inside the expanded image of the source image. A run length calculating part 6 calculates an expanded run length as the run length of black picture elements in the expanded image. A run difference calculating part 7 calculates run difference as the difference between this expanded run length and the maximum run length. An image class deciding part 8 compares the run difference with a previously set threshold value and decides the class of the input image for the unit of the expanded run based on this compared result.
