Title: Cleaning method of hollow fiber membrane
Inventor: SHINAGAWA MIKIO
IPC: B01D65/06
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To obtain an enough cleaning effect without requiring a high flow rate or pressure of water. SOLUTION: A hollow fiber membrane 1 is dipped in a mixture soln. of water to which 0.01-1wt.% surfactant and >=0.1wt.% alkali material are added. An org. matter 3 in a contaminant layer on the surface of the hollow fiber membrane 1 can be hydrolyzed by the effect of the alkali material, and the hydrolysis of the org. matter can be promoted by the permeation effect due to addition of the surfactant. As a result, contamination on the surface of the hollow fiber membrane 1 can be cleaned by washing with water in the ranges of flow rate and pressure of city water available for ordinary home.

Title: Hemoglobin adsorber
Inventor: SUGIYAMA MASAFUMI
IPC: A61M1/36
Filed: 1987-12-07
Abstract: PURPOSE:To adsorb and remove free hemoglobin in blood efficiently and selectively by packing porous silica having mean pore diameter of defined value into a column and made into a sterilizable adsorber by bringing it into contact with a solution containing hemoglobin. CONSTITUTION:Porous silica to be used herein is a porous material containing silica as the principal ingredient. As examples, silica gel and porous crystalline silica can be cited, and its mean pore diameter is 80Angstrom  or more. When the pore size gets larger too much, the obtained material adsorbs protein more than necessary, while decreasing hemoglobin adsorbing capacity, therefore, the pore size is preferably 500Angstrom  or less particulary 300Angstrom  is more preferable. The obtained adsorbent is especially effective in the removal of hemoglobin contained in blood caused by the extracorporeal circulation of blood. In this case, the adsorbent is packed in a column provided with access openings for blood. By flowing blood continuously in said column, the hemoglobin can be selectively adsorbed.

Abstract: PURPOSE:To allow the exact reincidence of misaligned light to a prescribed core part by providing reflecting bodies which reflect light beams around the respective core parts of an optical waveguide array and providing a sensor and galvano-mirror. CONSTITUTION:This scanner has the reflecting bodies 31 which are disposed vertically around the respective core parts 33 on the light incident end face side of the optical waveguide array 13, the sensor 16 which detects the reflected light from the reflecting bodies 31 on the outside of the optical path and the galvano-mirror 7 which is a 2nd optical deflector to deflect the light beam from a light source 11 to the direction perpendicular to the scanning direction by the signal from the sensor 16. The light beam which is misaligned by the poorness of the straightness, etc., of the optical waveguide array itself and fails to enter the core part 33 to which the light beam is ought to be made incident is reflected by the reflecting bodies 31 disposed around the core parts 33 of the optical waveguide array 13. To which side of the core array 32 the light beam is misaligned is detected by the sensor 16. The misaligned light is again made incident exactly to the core part 33 via the galvano-mirror 17 in this way and the misalignment is corrected.

Title: Magnetic reproducing device
Inventor: NAGASAWA MASAHITO
IPC: G11B5/588
Filed: 1988-12-06
Abstract: PURPOSE:To stabilize the characteristic of a tracking control system even when the mechanical characteristic of a magnetic head driving device is changed with time or the temperature characteristic thereof is changed by detecting the displacement quantity of a part to be driven in the magnetic head driving device with the aid of using a light source which flickers and controlling an auto-gain control circuit so that wobbling amplitude is always made constant. CONSTITUTION:The output of an oscillator 24 is transmitted through a rotary transformer 22 so as to drive to flicker a light emitting diode 18 with the aid of a pulse current (a), then light passes through the hole of a light supporting member 19 for stop and is received by a two-splitting photoelectric converter 20. The balance of the received light quantity of the photoelectric converter 20 is lost as the result of the displacement of a coil bobbin 2 and a displacement quantity signal (d) is detected. Only a wobbling signal component is extracted from the displacement detection signal (d) by a band-pass filter 36 and the auto-gain control circuit 29 is controlled through the band-pass filter 30 so as to make the wobbling amplitude constant. Thus, the wobbling amplitude is always made constant even when the displacement characteristic of the head is changed caused by the change with time or the temperature characteristic and the characteristic of the tracking control system is stabilized.

Filed: 1995-11-28
Abstract: PROBLEM TO BE SOLVED: To obtain a recording medium generating little noise and having a high S-N ratio by forming a region in which the concn. of C is high in the middle layer part of an Fe-C-O magnetic film.

Title: Production of carburized parts excellent in delayed fracture characteristic
Inventor: SHIRAGAMI TETSUO
IPC: C21D9/00
Filed: 1997-10-27
Abstract: PROBLEM TO BE SOLVED: To improve the delayed fracture characteristics of parts by subjecting a steel having a specified compsn. contg. Ni to oxidizing treatment, thereafter executing carburizing treatment and subsequently applying plating thereon. SOLUTION: The steel to be made the object is an Ni-contg. steel contg., by weight, >=0.3% Ni. Prior to carburizing treatment, this steel is subjected to oxidizing treatment. By this oxidizing treatment, an Ni-concentrated layer is formed directly below oxidized scale, which suppresses the infiltration of hydrogen to improve its delayed fracture characteristics. As the conditions of the oxidizing treatment, atmosphere, temp. and time are given, and, by changing these, oxidized scale with various thicknesses can be formed.  There is no limitation in particular as for the conditions therein, where, as for the conditions in which the thickness of the oxidized scale exceeds 10 μm, though the Ni- concentrated layer is made large, the dispersion of the torque in the screw part is easy to occur in the case it is used as final products, therefore, it is preferable that the conditions are set in such a manner that the scale thickness is regulated to <=10 μm.

Title: Stereo x-ray tube
Inventor: TSUCHIYA SADAO
IPC: H01J35/04
Filed: 1991-10-29
Abstract: PURPOSE:To provide an X-ray tube by which dosage is hardly reduced by inclining two inside/outside recess grooves to perpendicular of an X-ray emitting port, and making inclination of the outside recess groove larger than inclination of the inside recess groove. CONSTITUTION:Thermoelectrons generated from filaments 6 of focusing electrodes 4a and 4b in a cathode part are converged/accelerated, and collide with a target 2a of an anode, so that an X-ray is generated. In a stereo X-ray tube, since a focus is formed in a position dislocated from the center of the circular truncated cone shape target, electric potential distribution becomes asymmetrical to the center of the focusing electrodes. Thereby, distortion of the focus formed by an outside electrode groove 5RO among two electrode grooves of the same focusing electrode becomes large. In order to correct this, inclination of the outside electrode groove 5RO is made larger than inclination of the inside electrode groove 5RI. Since an outside focal shape is improved by this correction, the focus in which distortion is hardly caused both inside and outside can be obtained.
