  • Patent number: 11946941
    Abstract: The automatic analysis device 100 is provided with: a specimen dispensing mechanism 101 that dispenses subject blood plasma and/or normal blood plasma to be added to correct the coagulation time of the subject blood plasma, into a plurality of specimen containers 103; reaction containers 104 that contain the subject blood plasma and/or the normal blood plasma; a reagent dispensing mechanism 106 that dispenses a reagent into the reaction containers 104; and a detecting unit 113 which applies light from a light source 115 to the subject blood plasma and/or the normal blood plasma to which the reagent is added in the reaction containers 104, and which measures the coagulation time on the basis of the obtained scattered light and/or transmitted light.

  • Publication number: 20050118365
    Abstract: The invention provides a plastic container with a coated inner surface having superior gas barrier properties. It further provides a plastic container with a coated inner surface capable of suppressing elution of minor components from the resin, in addition to having the superior gas barrier properties. The container has on its inner surface an amorphous carbon film formed by plasma CVD from a starting material containing carbon atoms and whose main component is carbon. In the carbon film, when the number of carbon atoms contained in the film is 100, the ratio of the number of nitrogen atoms is 15 or less, or the ratio of the number of oxygen atoms is 20 or less, or the ratio of the total number of nitrogen atoms and oxygen atoms is 27 or less.

  • Patent number: 5581053
    Abstract: A diaphragm of an electroacoustic transducer is made of a material including fibers taken out of young stems of bamboo grasses and preferably, used as the material is paper made by mixing the fibers taken out of young stems of bamboo grasses and wood pulp in a predetermined ratio. Containing fibers taken out of young stems of bamboo grasses allows rigidity and internal loss characteristics of the diaphragm to be enhanced without increasing its density, thereby expanding a frequency band of the diaphragm. In addition, young stems of bamboo grasses can be gathered without affecting parent bamboo grasses, which prevents destruction of the environment.

  • Patent number: 5480514
    Abstract: The diaphragm of the electroacoustic transducer is made of a material in which fibers having at least two different radii taken out of wood are mixed together. Two mean radii A and B, among different mean radii of the fibers are set to satisfy the relationship: 0.5.times.A.ltoreq.B.ltoreq.0.5.times.A. By utilizing such a diaphragm, the balance of the density, rigidity, and internal loss of the diaphragm can be improved, and thus the acoustic characteristics of the electroacoustic transducer such as a speaker unit can be improved.

  • Patent number: 5327507
    Abstract: An inner-ear type headphone apparatus includes a diaphragm, a driving portion, a backside wall, and a sealed wall plane. A diaphragm backside space is formed between the diaphragm and the driving portion. The driving portion drives the diaphragm. A back cavity communicates with a diaphragm backside space. The back cavity is formed between the driving portion and the backside wall. There is a sound-absorbing space between the backside wall and the sealed wall plane. The backside wall is provided with through-holes communicating the back cavity with the sound-absorbing space. The sound absorbing space is separated from external space by the sealed wall plane. Sound output of low frequency range is enhanced for the user of the headphone apparatus, with satisfactory frequency characteristics maintained where there is no drop in sound output of middle frequency range. Also, the amount of leakage of unpleasant sound wave of high frequency range to external space is reduced.

  • Patent number: 4620606
    Abstract: A loudspeaker of plane diaphragm type has a skin-like material with smaller diameter than that of the plane diaphragm pasted thereon so that the skin-like material will not stick out of the diaphragm surface and the edge piece surrounding it can securely support the plane diaphragm, preventing unpleasant noises and split vibrations.
