Title: In vivo stay type stent
Inventor: SEKINE RYUTA
IPC: A61M29/00
Filed: 1990-02-23
Abstract: PURPOSE:To secure a lumen space by dilating a stent by elasticity when the holding force of a fixing member is eliminated by mounting the fixing member composed of a biodegradable material folding a tubular stent trunk composed of an elastic material in a form reducing the outer diameter thereof and bundling the same in the folded state. CONSTITUTION:A drainage (ERBD) tube 1 is composed of a stent trunk 2 composed of an elastic material stable in a living body such as silicone rubber or polyethylene and the stent trunk 2 is held in a folded state by a fixing member. The fixing member consists of strip-like rings 3, 3 and formed, for example, from a biodegradable material such as poly L-lactic acid or gelatin. The ERBD tube 1 is inserted in a bile duct 6 from the papilla 5 of the duodenum by an endoscope. The rings 3, 3 receive degradation several days after the ERBD tube 1 is inserted to be lowered in strength and the sent trunk 2 is delated by elasticity to slightly dilate the constricted region due to a cancerous tissue part 8. After several days, the rings 3, 3 are degraded to be perfectly broken and the stent trunk 2 is delated to be restored to the original shape and the constriction region due to the canerous tissue part 8 is also dilated to secure a lumen space.

Title: Magnetic toner
Inventor: NOGUCHI KOUJI
IPC: G03G9/08
Filed: 1980-03-31
Abstract: PURPOSE:To improve the quality of an image by mixing two kinds of magnetic powders of needlelike and cubic system crystals to prepare a PPC system one-component magnetic toner consisting of magnetic powder and thermoplastic resin. CONSTITUTION:Magnetic powders of needlelike crystals 3 and cubic system crystals 2 are mixed in 2:8-8:2 ratio and contained by 30-65pts.wt. to 100pts.wt. of toner 1 to adjust the electric resistance of the toner to 10<10>-10<16>OMEGA-cm. Cubic system crystals cause uneven development, and it is difficult for needlelike crystals to produce halftone, yet by mixing both the crystals, the properties are improved. When the part weigh of the magnetic powders is reduced, the scattering amount is  increased to cause ground fog. On the other hand, more magnetic powders extremely lower the fixability of the toner, scratch a photoreceptor, and make the electric resistance unsuitable. The magnetic characteristics of a toner contg. a single kind of magnetic powder can be fitted to those of this toner contg. the mixed powders, but this toner provides higher quality to an image.

Filed: 1986-02-28
Abstract: PURPOSE:To prevent the variance of brightness and the break of color balance by making effective areas of respective color elements different from one another so that their outputs are uniform in one picture element. CONSTITUTION:With respect to a color filter used in a color liquid crystal display device, area rates of respective color elements B, G, and R in a picture element 1 are made different from one another in consideration of spectral characteristics and luminous efficiencies of the color filter and a light source. With respect to the color filter used in a color photosensor, area rates of color elements 14B, 14G, and 14R brought into contact with individual electrodes 16B, 16G, and 16R are made different from one another in consideration of the spectral sensitivity characteristic of a photoconductive layer. By this constitution, the brightness of the color filter used in the display element or device is uniformized to improve the color balance.

Title: Device for working outer peripheral surface of disk
Inventor: SUZUKI AKIRA
IPC: G11B7/26
Filed: 1990-02-22
Abstract: PURPOSE:To allow the cutting of the outer peripheral surface of a disk without generating cracks in the base material and signal recording layer of the disk by rotationally operating the disk and cutting the outer peripheral surface of the disk by means of cutting tools. CONSTITUTION:The disk 102 is head near the outer peripheral part by a turn table 11 which sucks and holds the part near the outer peripheral part of the disk 102 and a retaining member 15. The oscillation of the outer peripheral part of the disk 102 is, therefore, obviated at the time the disk 102 is rotationally operated by a rotational driving means. The disk 102 does not, therefore, oscillate with the cutting tools 9, 10 supported movably forward and backward relative to this disk 102. The disk is thus well cut by the cutting tools 9, 10. The outer peripheral surface of the disk is cut in this way without generating cracks in the base material and signal recording layer of the disk.

Title: Serial printer
Inventor: HASHIMOTO TAMAMI
IPC: B41J29/48
Filed: 1988-02-26
Abstract: PURPOSE:To prevent a recording material support part or the back side of the next recording material from being contaminated, by inhibiting recording when the absence of a recording material is detected by a recording materialdetecting means. CONSTITUTION:In the case of receiving recording data from a host device 14, the recorded data is analyzed, and when a recording-starting instruction is provided, the left and right end positions in the received recording data are calculated. Further, the shortest of the distances of the left and right end positions from the current starting position of a carriage 3 are calculated. A carriage 3 is moved to the end position corresponding to the shortest distance, and is moved to a recording position, and the presence or absence of a sheet on the front side of a recording head is detected by a sheet detector 2. When the sheet is absent, recording data read from a RAM 13 is converted into white data, which is transferred to a head controller 18. Next, when recording by scanning is not finished, the carriage 3 is further moved, followed by sheet detection by the sheet detector 2, and when recording is finished, the next process is started. Since recording by the recording head is inhibited when the absence of the recording material is detected, it is possible to prevent a recording material support part of a printer, the back side of the recording material or the like from being contaminated.

Filed: 1983-03-15
Abstract: PURPOSE:To stabilize both positive and negative outputs by comparing and detecting the variances of both outputs to give the detected variance to an amplifier provided at the primary side and driving a series control circuit by said amplifier. CONSTITUTION:The partial voltage VA of a voltage detecting circuit 35 rises up when the +V output has a rise due to an input variance, etc. When the VA exceeds the voltage of a Zener diode DZ, the collector current ID of a transistor TRQ3 of an error amplifying circuit 34 increases. Then the current of a light emitting element LED of a photocoupler PC1. As a result, the quantity of light emission of the LED increases and the collector current Ic of a phototransistor PTR of a photodetecting element set opposite to the LED is increased. The collector current I3 of a TRQ2 of an amplifier 36 increases with increment of the current Ic. As a result, the base current I2 of the TRQ1 is reduced. Then a control circuit 30 is controlled in the direction where the rise value of the positive and negative outputs is eliminated.

Abstract: PURPOSE: To manufacture a voidless, heat-resistant insulating tape useful for the insulation of a driving DC motor of a vehicle, by treating the surface of mica or glass which is a component of substrate, with a solution of catalyst containing a coupling agent.  
     CONSTITUTION: A substrate containing mica sheet or glass cloth is impregnated with a resin containing a polyfunctional isocyanate and a polyfunctional epoxide (IO Resin), and slitted to tapes. The tape is treated with a solution of a catalyst containing a coupling agent of formula R'WSi(RO) 2  or R'WTi(OR) 2  (R' is organic functional group; OR is hydrolyzable alkoxy, acetoxy, etc.). The OR group is hydrolyzed to OH by the trace of water in the catalyst solution, and forms a bond to the silanol group of the surface of glass, mica, etc. Consequently, the surface is occupied with R' group, which does not generate CO 2  by the reaction with the polyfunctional isocyanate of the IO Resin, and the voidless insulation is obtained.
