Title: Fine vibration scalpel for surgery
Inventor: YOKOYAMA MASAYOSHI
IPC: A61B17/3211
Filed: 1990-08-03
Abstract: PURPOSE:To achieve a delicate surgical operation accurately by arranging a vibration member which controls energy to be generated with the rotation of a motor to apply a fine vibration with a specified amplitude to a blade part. a transmission member which transmits vibration to the blade part while having an engaging part detachable from the blade part and the blade part detachable from the transmission member. CONSTITUTION:A rotating shaft of a motor M is equipped with an eccentric disc 6 having a protrusion 6' decentered. The eccentric disc 6 turns with a rotary shaft of the rotating shaft of the motor M, so that the protrusion part 6' vibrates vertically. This vibration is transmitted to a blade part with a transmission member 2 detachable from the blade part 1. The transmission member 2 has two guide grooves 11 and vibrates vertically being supported with a support rod 4 extending from a housing wall 3. As a result, the blade part vibrates vertically as indicated by the arrow. The motor is enough only if it can drive with a dry battery and so, a driving capacity just made available by an electric razor or electric tooth brush is sufficient. The shape of the blade part is preferably with an acute angle of 20-30 deg.. This enables excision accurately simply by making a contact with a part desired to be cut.

Abstract: PURPOSE:To observe a living body with high resolution by converging X rays on the sample through a single concave aspherical multi-layered mirror condenser and enlarging a sample image on a two-dimensional X-ray image pickup element by using a phase zone plate. CONSTITUTION:A plasma X-ray source consisting of a pulse laser 1 is used as a pulse X-ray source and laser light is converged on a target 5 to generate X rays from an extremely small area; and the target 5 is arranged at the 1st focus of a rotary elliptic multi-layered film reflecting mirror and the sample 13 is arranged at its 2nd focus. The multi-layered film mirror makes the X rays monochromatic and one X-ray pulse excited and emitted by the pulse laser 1 is used for photon counting image pickup operation. The intensity of the X rays of the pulse X-ray source is adjusted so that 25<=nmax<lambda/DELTAlambda, where lambdais the wavelength of the X rays, DELTAlambda is the spectrum width, and nmax is the maximum number of detected photons incident on each picture element of the two-dimensional image pickup element 16. Thus, the photon counting image pickup operation is performed with one pulse.

Title: Compaction molding method of powder material
Inventor: ARAKI SHINICHI
IPC: B22F3/035
Filed: 1984-10-02
Abstract: PURPOSE:To prevent the injury of a molding by a die by subjecting the molding to high-pressure molding between upper and lower punches then releasing the pressurizing force of the upper punch, holding the molding under the low pressure, lowering the die in this state and delivering the molding. CONSTITUTION:Raw material powder P for a grinding stone is uniformly packed into a molding part 26 formed of the lower punch 23 and the die 24. The upper punch 22 is lowered and the powder P is molded under a high pressure of about 2-15tons/cm<2>. The presurizing force of the upper punch is then lowered down to about 1 ton/cm<2> and the grinding stone W formed between the upper and lower punches 22 and 23 is held. While this state is maintained, the die 24 is slid along the outside circumference of the lower punch 23 and is thus pulled down. The upper punch 22 is raised in succession thereto to impose the stone W on the punch 23 and in this state the stone W is delivered. The molding of the long-sized grinding stone is thus made possible without injuring the stone W by the die 24.

Title: Optical speed sensor
Inventor: WADA FUMIO
IPC: G01F1/66
Filed: 1981-12-23
Abstract: PURPOSE:To measure accurately the moving speed of a moving object, by making use  of the fact that a phase shift is produced between the light traveling toward the moving direction within the moving object and the light traveling opposite to the moving  direction of the moving object. CONSTITUTION:A fluid flows like an arrow A within a pipe 1 made of a transparent  material, and a polarizing separator 2 and mirrors 3a, 2b and 3c are provided along the  pipe 1 to form an optical path to the light made incident to the separator 2 like an  arrow E. The light made incident to the separator 2 in the direction of the arrow E is  separated into P and S polarized beams. The polarized beam P travels the optical path  forward to the flow A of the fluid as shown by an arrow B. On the contrary, the  polarized beam S flows like an arrow C and travels the optical path backward to the  flow A. The beam S comes back to the separator 2 and is coupled again to be made incident to a photodetector 4. In this case, both beams P and S have a difference of  phase which is proportional to the speed of fluid. Therefore, the light made incident to  the detector 4 like an arrow D varies its intensity with respect to the original light E  and in response to the speed of fluid. As a result, the fluid intensity is known within  the pipe 1 by measuring the intensity of the light made incident to the detector 4.
