摘要： A sleeve and a hub are fixed to each other, and then the sleeve and the hub are gripped and rotated around a central axis, during which cutting is performed over the inner peripheral surface of the sleeve and a flange surface of the hub. Thus, the flange surface can be finished accurately such that the flange surface is normal to the central axis and the inner peripheral surface of the sleeve.

摘要： A rotor unit includes a substantially circular plate shaped cover portion, a rotor hub including a lower cylinder portion, and a magnetic field generating member attached on the lower cylinder portion. An annular salient portion is provided on the lower surface of the cover portion 31. The annular salient portion lies radial inwards of the lower opening of the through-hole of the cover portion and protrudes downwards in the shape of a ring whose center coincides with the central axis. The magnetic field generating member includes a rotor magnet and a back iron covering the outer surface and upper surface of the rotor magnet. When the magnetic field generating member is mounted to the rotor hub, the upper portion of the back iron comes in contact with the annular salient portion, which determines the axial position of the magnetic field generating member.

摘要： A bearing mechanism includes a shaft, a sleeve portion, a thrust portion, and a cover portion. Lubricating oil is arranged in a communicating channel in the sleeve portion, a thrust gap between the sleeve portion and the thrust portion, and a tapered gap between an outside surface of the thrust portion and the cover portion. A lower end opening of the communicating channel is defined in an outer circumferential portion of a lower surface of the sleeve portion radially outward of the thrust gap. A radially outermost portion of the thrust portion is arranged either tangent to a wall surface of the communicating channel or closer to a central axis than the wall surface. The tapered gap is arranged closer to the central axis than a radially outermost point of the wall surface. The outer circumferential portion and the cover portion define a guide gap therebetween.

摘要： A blood test apparatus having a simple constitution whereby stable measurement can be conducted by surely sampling the blood in an amount being small but sufficient for the test without placing too much burden on a patient. When a first skin contact sensor of this apparatus detects the skin, driving of a negative pressure unit is initiated. Thus, the skin rises and comes into contact with a second skin contact sensor. After piercing into the skin, the negative pressure supply is once ceased. Next, the negative pressure is applied again for a definite period of time. Thus, the opening in the skin is broadened, which facilitates the flow out of the blood.

摘要： A blood test device using a laser as a puncture member. More specifically, in a blood test device using a laser as a puncture member, the skin can be fixed at a definite position by raising the punctured skin under negative pressure, and thus the skin is brought into close contact with a blood sensor and the laser is focused on the vicinity of the blood sensor face. Thus, it is possible to provide a blood test device of the laser puncture type in which the skin can be surely punctured while giving little pain to a patient.

摘要： A blood test apparatus wherein a blood collection needle and a blood sensor can be easily attached and detached so that a burden or pain of a patient can be relieved. More specifically speaking, a blood test apparatus wherein a holder, a lancet, a blood collection needle and a blood sensor are united together as a blood sampling cartridge that is detachably mounted to the apparatus body. When this blood sampling cartridge is attached, a plunger involved in the apparatus body holds the lancet and connectors involved in the apparatus body come into contact with the blood sensor. It is preferable that the contact points with the blood sensor of the individual connectors are located at intervals at the same angle centering on a definite point.

摘要： A blood sensor usable both for a blood inspection device that performs puncture with a puncturing needle and for a blood inspection device that performs puncture with laser. In concrete, this invention comprises a sensor unit having a holder and a blood sensor mounted to the holder and a needle unit having a slidable puncturing needle. The needle unit provides a blood sensor block detachably fitted to the inside of the holder of the sensor unit. The blood sensor block is applied to a needle-puncturing type blood inspection device. The sensor unit from which the needle unit is removed is applied to a laser-puncturing type blood inspection device.
