Title: Three-dimensional actuator
Inventor: AOYAMA NAOYUKI
IPC: H01J37/20
Filed: 1989-06-30
Abstract: PURPOSE:To enable high-precise three-dimensional positioning over a wide range and to inhibit respective three-dimensional axes from interfering one another by providing mutually parallel elastic rods of four-rode constitution which are interposed between piezoelectric elements and a moving body and support the moving body flexibly. CONSTITUTION:The three-dimensional actuator 1 so constituted that the three piezoelectric elements 2 which are displaced along the respective X, Y, and Z axes support the moving body 4 flexibly through the four elastic rods 3. Then voltage is applied to, for example, the element 2 corresponding to the X axis and then the moving body 4 moves by a specific distance DELTAX in the X-axial direction. At this time, the elastic rod 3 interposed between the Z axis and moving body 4 operates as a parallel spring to inhibit the interference with other axes. Further, the moving body 4 is supported elastically and flexibly by the parallel four-rod constitution of the elastic rods 3, so the moving body 4 is inhibited from rotating on the movement displacement axis at the join position between the both.

Title: Method and device for cutting optical fiber
Inventor: SUDA HIROHISA
IPC: G02B6/25
Filed: 1986-07-21
Abstract: PURPOSE:To uniformly cut respective cores and to prevent cut surfaces after the cutting from contacting each other by constituting a couple of clamps so that they can leave each other and energizing them in the leaving directions. CONSTITUTION:When a bare wire part F1 in an extended state is fixed to a fixed clamp and a handle 13 is rotated, a main clamp 3 is lowered by its own weight and the internal edge of the short side 12a of a lever 12 contacts the upper edge of a bearing 8, so that the main clamp 3 is pressed down against the tensile force of an optical fiber F. In this state, a gap is still present between the bearing 8 and the straight part 11b of a cam 11 and the bare wire part F1 of the optical fiber F is therefore tensed by the weight of the main clamp 3. A blade body N is brought into contact with the bare wire part F1 to form a cut and then a pressing member is applied thereto to cut the optical fiber by bending. Consequently, the cutting position becomes constant and the main clamp 3 falls by the gap between the bearing 8 and the straight part 11b of the cam 11 after cutting to prevent the cut surfaces of the bare wire part F1 from contacting each other, so none of the cutting surfaces is flawed.

Title: Manufacture of case-hardening steel excellent in rolling fatigue characteristic
Inventor: IKEDA TATSUO
IPC: C21C5/28
Filed: 1986-07-21
Abstract: PURPOSE:To stably obtain a case-hardening steel excellent in rolling fatigue characteristic, by reducing respective contents of harmful P, S, Ti, and O2 by means of prerefining of molten pig iron as raw material, slag minimum refining in a converter, and secondary steel refining and also by inhibiting central segregation at continuous casting by means of electromagnetic agitation at the time of refining a case-hardening steel. CONSTITUTION:The molten pig iron is subjected to prerefining by the use of dephosphorizing agents and desulfurizing agents in a pretreatment furnace to undergo dephosphorizing and desulfurizing treatments into P<0.010wt% and S<0.007wt%, respectively. This molten pig iron is charged into a converter and is subjected to slag minimum oxygen blow smelting, as it requires neither dephosphorization nor desulfurization, so as to be refined into steel by means of decarburizing reaction. At the time of this decarburizing refining, Cr as an essential element for case-hardening steel is added in the form of Fe-Cr and, simultaneously, Ti contained in a Cr source is reduced to <=10ppm. After that,the above steel is subjected to deoxidizing refining until O2<7ppm is reached by means of secondary steel refining outside the converter, which is formed into a continuously cast billet free from central segregation by means of a continuous caster equipped with an electromagnetic agitating device. In this way, the case-hardening steel having a composition containing, by weight, 0.005-0.35% C, <=0.005% P, <=0.005% S, <10ppm Ti, and <7ppm O2 and excellent in rolling fatigue characteristic can be manufactured.

When serum or plasma is sucked from the cup 103, the liquid level in the cup 103 is detected by a liquid level sensor 70 to calculate the liquid level height. Subsequently, the amount of serum or plasma which can be sucked is calculated according to a predetermined calculation formula using the liquid level height, the radius of the cup 103 and a hematocrit. In the case of the suction from the cup 101, the hematocrit is set to zero and operation is performed according to the same formula. By this method, a proper amount of a specimen can be sucked with respect to the container receiving only serum or plasma and the container containing blood clot by a common apparatus.
