摘要： PURPOSE:To prevent the vibration of a drive power source from being transmitted to a mechanism, by rotatably supporting an intermediate shaft in the belt transmission mechanism with a fluid bearing further giving the tension to a belt between the intermediate shaft and a driven shaft by a connecting rod with a vibro-isolator. CONSTITUTION:For an intermediate bearing 18 for rotatably supporting an intermediate shaft 7, a fluid bearing is used to separate the rotary motion system and the supporting system of a 3-knuckle link. Here the bearing rigidity K1 at the side of a drive power source 1 of the intermediate bearing 18 is arranged to a level equal to or not higher than the bearing rigidity K2 at the side of a rotated body 3. To a connecting rod 12 for further giving the tension to a belt 9 between the intermediate shaft 7 and a driven shaft 4, a vibro-isolator 13 is further provided. Here the spring constant K of the vibro-isolator 13 is determined from the below described formula of relation with mass M of the rotated body 3 in such a manner that the characteristic frequency fn of a vibration system is fully low. fn=(1/2pi)(K/M) . In this way, a belt transmitting vibrationless transmission mechanism of turning effect without transmitting vibration of the drive power source 1 can be obtained.

摘要： PURPOSE: To facilitate several kinds of tests or assays of different reaction times by providing two washing probes on a device wherein a sample/reagent is added, then incubated and washed, far measuring a content in a reaction vessel. CONSTITUTION: A reagent wheel 44 receives a reagent cartridge 52, and a reagent wheel 22 assigned coaxially in the wheel 44 receives a reagent, a standard substance and a special reagent held in a reagent cup 23. Then, a barcode label of the cartridge 52 is read with a barcode reader 16, and, a cluster 30 of a reaction vessel 66 is assigned around a reaction wheel 58 which rotates in a step-by-step manner. A fluoro-meter 64 measures a fluorescence intensity, and a pipette device 28 transports a liquid from the cup 23, the cartridge 52 and general reagent vessels 22 and 26 to the vessel 86, and a rinsing drain source 70 washes a pipette probe during each use. Then a washing source 76, through a peristaltic pump 78, sucks the liquid from the vessel 66, and releases a washing buffer to the vessel 66, so that a magnetic particle is separated from the liquid in the vessel 66.

摘要： PURPOSE:To do away with excessive machining load and impact on work piece for lesser machining distorsion by switching between feeding speed control of a feed unit and feeding speed control of machining load according to the grinding condition. CONSTITUTION:As long as the grinding load does not exceed the force of the weight 22, i.e., the contact of a hook 30 is not released, or in other words, under the working condition where the feed speed is regulated within the range of the grinding capacity(speed) of the grindstone 32, a feed unit 20 sends a grindstone rotating unit 16 near to a rork rotating unit 12, successfully understaking slow feed at the beginning of cutting or control of stopping location of cutting. When the speed of the feed unit 20 becomes greater than the grinding capacity (speed) of the grindstone 32, the contact of the hook 30 is released to equalize the grinding load and the force of the weight 22. Thus, work piece 1 is machined at the rate suitable to the cutting quality of the grindstone 32 under the machining load control method.

摘要： PURPOSE:To reduce deformations owing to working and heat treatment and prevent deformations and aging owing to changes in ambient temperature by so cutting out the strain inducers that the displacement direction of the strain inducers in which strains are produced by receiving the displacements of mechanical quantity-electric quantity transducers become parallel with fiber or rolling plane. CONSTITUTION:A cantilever 11 is so cut out that its displacement direction becomes parallel with the rolling plane and becomes perpendicular to the rolling direction of rolling material 10. And the fiber plane shown by using many lines and the displacement direction of force point part 3 are made parallel. The surface of the strain inducing part formed by cutting away recesses 4, 4' becomes perpendicular to the rolling and fiber planes and a stain gauge 5 is secured to part of the face thereof by using an adhesive agent.

摘要： PURPOSE:To prevent the reflection of unnecessary light by mounting on the surface of a wall to be irradiated a foam so that a very fine foreign substance such as kneaded compounds does not appear to reduce light intensity with the bubble of the foam and the like. CONSTITUTION:Light is directly or indirectly incident upon a foam 3 mounted on the surface of the wall of a pellicle frame 2 to irradiate. The radiated light enters into the bubble of the foam 3 to make irregular reflection, and the irregularly reflected light is finally brought into the absorbed state to reach such a state as not to exert a bad influence upon externals. That is, the foam 3 absorbs light and does not reflect light by itself. Then, a pellicle 4 is applied on the reticle pattern surface of a reticle 1 for the prevention of sticking very fine foreign substances and however when a laser beam enters into the inner wall surface of the pellicle frame 2, it is irregularly reflected in the case of the foam 3 being not provided there. Therefore, the foam 3 is stuck by a bonding agent in a particular position to absorb light, thereby eliminating erronous detection.

摘要： PURPOSE:To obtain a standard device in which a processing liquid can be supplied to a shaft core hole of a high speed rotary body; such as a rotary spindle, without losing balancing accuracy and also without contacting it. CONSTITUTION:A jetting pipe 1 is inserted into a shaft core hole 3A of a rotary body 2 leaving a tiny gap (such as an order of 5-100mu), and a liquid to be fed by pressure is pressed into the rotary body 2 through the jetting pipe 1 so that it can be supplied to a work section from a hole 3B on the top end section. The hole of the rotary body 2 is to have a fluid passage having a drawing resistance R1 at a top end section 3B and a liquid-sealing resistance R2 at a tail end section 3A. By making the resistance R2 larger than the resistance R1, leaking of the liquid can be decreased. In order to achieve this, it is to have a gap being as small as 5-100mu and as long as 2-50 mm.
