Title: Production of superconducting film
Inventor: NOJIMA HIDEO
IPC: H01B12/06
Filed: 1990-01-09
Abstract: PURPOSE:To easily obtain a superconducting film having desired characteristics with precision by dispersing a superconducting fine powder into an org. solvent, forming a film on a copper sheet by electrodeposition and sintering the film under the conditions where the fine powder is partially sintered. CONSTITUTION:The superconducting fine powder (e.g. Y-Ba-Cu-O-based superconducting fine powder) is dispersed into an org. solvent (e.g. acetone) to prepare a soln. 2. A conductive electrode 3 is then dipped in the soln. 2, and a copper substrate 1 is arranged on the negative potential side. An electric field is impressed between the electrodes 3 by a constant-voltage power source 4 to deposit a superconducting film on the substrate 1 by electrodeposition. The substrate 1 is then brought out, and sintered under the conditions where the fine powder in the film formed on the substrate 1 is partially sintered, and a superconducting film is obtained. Consequently, the heat treating time is controlled, the effect of a CuO layer formed at the interface is avoided, and the characteristic of the film is controlled.

Title: Ct system
Inventor: UDA SHINICHI
IPC: A61B6/03
Filed: 1998-01-09
Abstract: PROBLEM TO BE SOLVED: To make it possible to reduce a number of image arch facts in a spiral scanning by setting a second spiral data range, by which the ending point of measuring the first spiral data range exactly meets its beginning point, and by retrieving all the spiral data of the first/second spiral data ranges to reform all the images individually. SOLUTION: Continuously turning both the X-ray source 1 and the X-ray detector 2 continuously moves the bed 3 back-and-fourth to execute a spiral scanning. The two-dimensional buffer 12 stores all the X-ray detection signals obtained by the data collection circuit 2A, in accordance with the addresses to be determined by the measurement cycle/projection numbers. The projection data forming circuit 13 then sets a second spiral data range for the spiral data to have the ending point of measuring the first spiral data range meet its beginning point, as well as a first spiral data range for those held in the two-dimensional buffer 12 to reform the tomogram at a specific position. The reverse- projection operation circuit 15 executes the reform operation for projection data.

Title: Laser diode-excited solid state laser
Inventor: SENOO TOMONOBU
IPC: H01S3/108
Filed: 1989-01-12
Abstract: PURPOSE:To enhance conversion efficiency to second harmonic by providing a nonlinear optical crystal and subjecting the laser oscillation light of a solid- state laser to multiple reflection. CONSTITUTION:A nonlinear optical crystal 4 is disposed in a state inclined with respect to the optical axis of the laser oscillation light of a solid state laser, and a basic wave omega (laser oscillation light of a solid state laser) generated in a resonator is introduced into a crystal through a reflection preventive film 11. Here, omega is the frequency of light. The crystal is so cut in a crystal orientation as to enhance the nonlinear optical effect in the propagating direction of a basic frequency omega in the crystal, thereby regulating the inclining angle. The omega light in the crystal is multiple reflected in the crystal via high reflecting films 10, 10' while converting the part into secondary harmonic waves 2omega, emitted from a reflection preventive film 11', and emitted laser light 7 is output via an output mirror 5 for the resonator. Thus, the more the number of the reflections is large, the longer the crystal length equivalently becomes, thereby enhancing the conversion efficiency of the secondary harmonic wave.

Title: Method of lubricating rolling bearings
Inventor: TOUMA KATSUYA
IPC: F16C33/66
Filed: 1978-01-19
Abstract: PURPOSE: To reduce friction in the rolling bearing and raise the cooling effect through an intermittent supply of lubricant by means of a barrier with a notch provided betwen the bearing and a feed nozzle.  
     CONSTITUTION: A barrier 4 is provided on a rotating shaft 1 between a feed nozzle in such a manner as to turn with the inner ring of a rolling bearing 2. When the shaft 1 turns while a lubricant is injected through a feed nozzle 6, the barrier 4 rotates with the shaft 1. In this manner, the lubricant is fed intermittently to the bearing 2 through the nozzle 6 each time the notch 41 formed on the barrier passes in front of the nozzle. The lubricant hitting on the portion of the barrier other than the notch is dispersed around the bearing thereby raising the cooling effect. Adjusting the size of the notch allows the lubrication with a limited feed while the use of a nozzle relatively large in diameter can prevent the loading of the nozzle.

Title: Image formation method, image formation controller and image formation system
Inventor: KURITA TETSUO
IPC: B41J2/44
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To suppress the increase of cost due to enlargement of the storage area of an image formation device and also to assure the formation of images with high quality. SOLUTION: When a print information analysis part 202 of a host computer 200 sends the dummy data to an LBP (laser beam printer) 100 via a print instruction generation part 204, a print information control part 208 of the LBP 100 returns the reception confirmation information on the dummy data to the computers 200. A timer 202a counts the time needed for transmission of the dummy data, and this data transmission speed is calculated from the count time of the timer 202a and compared with the data processing speed of the LBP 100. When the former speed is lower than the latter one, the resolution of the image signals to be transmitted to the LBP 100 are reduced. Thus the quantity of dummy data is reduced and the time needed for transmission of the data is coincident with the data processing speed of the LBP 100.

Title: Hydraulic bush type vibration isolator
Inventor: TABATA TOSHIYUKI
IPC: F16F13/14
Filed: 1988-01-12
Abstract: PURPOSE:To make speedy assembling performable with accurate assembling dimensions by constituting an outer wall of a hydraulic chamber on one side with an elastic film supported on an outer cylinder, and notching a part conformed to this elastic film in the outer cylinder. CONSTITUTION:A body being made up of vulcanizing and bonding an elastic body 20 to an interval between an inner cylinder 12 and an intermediate cylinder 18 is inserted into an outer cylinder 14 in submergence. If so, a liquid is filled up in both of a hydraulic chamber 26 and a limiting passage 32. Since an elastic film 16 is vulcanized and bonded to the outer cylinder 14, a recess 16A makes the shafting circumferential direction and an axial assembling position accurate easily and can be housed in an elastic recess of the body. In this state, such drawing that contracts an outer diameter of the outer cylinder 14 is carried out whereby a vibration isolator 10 is completed, then this isolator is taken out of the submergence. Consequently, the liquid on the outer circumference of the recess 16A quickly flows out from a notch 14A, so that no liquid comes to existence without requiring any work. Thus, since it accurately corresponds to each and is accurately positioned, such a possibility that the limiting passage 32 is partially closed or the liquid inside the hydraulic chamber is leaked out will not occur, and thus speedy assembling is performable with accurate assembling dimensions.
