Title: Forming method of deep drawing part
Inventor: NAGAI YASUTOMO
IPC: B21D26/047
Filed: 1999-09-22
Abstract: PROBLEM TO BE SOLVED: To provide a forming method of a deep drawing part capable of producing a deep drawing part in a short time and at a low cost while preventing a crack and buckling. SOLUTION: A cup shaped work 4 is arranged in a drawing die 5 having a drawing part 5b to make an inner diameter narrow downward, by covering an opening part 10 of the work 4 with an axial force punch 2 and pressing in a state in which its inside is filled with a liquid, the liquid is compressed/ pressurized while pressing the end part 11 of the opening part 10, the work 4 is pressed on the inner face of the drawing die 5 to be bulged into the drawing part 5b thereunder. Because the work 4 is formed while pressing-in with the axial force punch 2, the work 4 is pulled to avoid a crack. On the other hand, buckling of the work 4 due to pressing-in is prevented so that the work 4 is pressed on a drawing die 5 inner face by an inner pressure of the fluid compressed/pressurized with the axial force punch 2. Further, because the work 4 is bulged in the drawing par 5b and appropriate tensile force is acted to a work tip part 4c, and the buckling is avoided.

Title: Detection method for porphyrin on skin
Inventor: NAGASHIMA YOSHINAO
IPC: G01N33/50
Filed: 1991-10-17
Abstract: PURPOSE:To detect easily and accurately skin surface porphyrin inclusive of a measurement place as a color image and conduct observation by preventing the temperature ascent of a CCD by cooling the CCD by means of a cooling mechanism, using feeble ultraviolet rays that contain visible light and do not have a bad effect on a skin. CONSTITUTION:In the case of a Peltier cooling type CCD color camera 4, cooling is carried out by means of a Peltier element to prevent the temperature ascent of a CCD module. Also, the temperature ascent of the Peltier element is cooled by means of a circulation liquid from a cooling drive unit 5. Thus, when spectrum is received, a color image signal that is normal at all times can be outputted. As a result, skin surface porphyrin can be detected and observed quickly with ease and accuracy as a color stationary image through a TV monitor 7 even at a feeble ultraviolet ray quantity without causing a bad effect on a skin. Also, visible light is contained in irradiation light from a light source 1, too, so the contour of the place of a human body also can be indicated as an image, and a porphyrin measurement place can come to be grasped clearly.

Filed: 1986-11-13
Abstract: PURPOSE:To detach a disk cartridge through the application of a small force by providing a projection at the internal face position of the cartridge, which is in contact with the outside surface of the information region of the face A and the face B of an optical disk.

Abstract: PURPOSE: To prevent the fall of foreign matter on a recording paper, and secure a uniform contact pressure between a cleaning member and a heating roller by providing a collecting means of the removed foreign matter through the cleaning member, which removes the foreign matter such as a toner or the like stuck to the peripheral surface of the heating roller, in the cleaning member itself. CONSTITUTION: In the structure of a cleaning member 4, the tip part of a stuck matter containing part 42 is made to be upward from the horizontal direction so that the inner side of the stuck matter containing portion 42 is made to incline downward. A remaining toner is not allowed to stick to and remain in the tip portion, but the stuck matter can surely be fed to the stuck matter containing part 42 arranged behind. The width of a heating roller touching part 41 is set to be wider than the width of a temperature detection member so as to collect the lump and the like of the separated foreign matter from the temperature detection member mainly.  Since the width of the touching part 41 is not allowed to reach the full length in the width direction of a heat-sensitive roller but is set to exceed the width of the temperature detection member by predetermined length, contact pressure between the touching portion 41 and a roller peripheral surface can easily be maintained uniform.
