摘要： A casing of a regenerative pump forms a generally annular fluid passage, which conducts a fluid. An impeller is rotatably received in the casing and has a plurality of blades, which are arranged one after another in a circumferential direction to provide kinetic energy to the fluid in the fluid passage upon rotation of the impeller. The regenerative pump satisfies a relationship of 0.60≦b/a≦0.76, where “a” is an axial width of each blade, and “b” is a total axial distance, which is a sum of a first axial distance between a first axial side outer edge of the blade and an opposed first axial side inner wall of the fluid passage and a second axial distance between a second axial side outer edge of the blade and an opposed second axial side inner wall of the fluid passage.

摘要： A regenerative pump includes a casing having a fluid passage connecting an inlet with an outlet. An impeller has vanes faced to the fluid passage that includes an arc passage. An outlet passage communicates with the outlet. The outlet passage is substantially constant in cross sectional area. A communication passage connects the arc passage with the outlet passage. The casing has an inner wall that defines the communication passage. The inner wall is in a curved shape in an axial section that includes a center axis of the communication passage and extends along a center axis of the casing. The center axis of the communication passage and the outer circular profile of the impeller define an intersection therebetween. The communication passage has a vertical section, which includes the intersection, being perpendicular to the center axis of the communication passage. The inner wall reduces a crosssectional area of the communication passage in the vertical section.

摘要： In a method of measuring a viscosity of a sample based on a rotation frequency ΩS of a conductive rotator rotating by applying a rotating magnetic field from outside to the rotator set in a container containing the sample and a rotation frequency ΩB of the magnetic field, a constant k1 having temperature dependency of an apparatus and a constant k2 not having the temperature dependency at each temperature are found by using a equation, η0Ωs=k1(ΩB−ΩS)−k2, where a viscosity η0 at specific temperature is known, and then a value of viscosity measured at the specific temperature is corrected by means of the constants k1 and k2, the rotation frequency ΩS of the rotator, and the rotation frequency ΩB of the magnetic field. The constant k1 may employ the temperature dependency of electric conductivity of metal used to the rotator.

摘要： In a combustion heater, at the time of ignition, a fuel supply amount is increased in a stepwise fashion. On the other hand, at the time of extinction, the fuel supply amount is decreased in a stepwise fashion. The fuel supply amount is increased stepwise using different fuel increasing amounts or different fuel increasing periods, both depending on heat quantities generated by a burner at respective fuel increasing time points. At the time of extinction, the fuel supply amount and an air supply amount are both reduced to given values, respectively, and held at the given values for a given time period. After lapse of the given time period, the fuel supply amount is reduced to zero, while the air supply amount is held at the given value for a further given time period. The air supply amount is changed with a given time delay relative to a change of the fuel supply amount. The time delay may be adjusted depending on a temperature in the burner.
摘要翻译： 在燃烧加热器中，在点火时，以逐步的方式增加燃料供给量。 另一方面，在灭火时，燃料供给量以逐步的方式减少。 使用不同的燃料增加量或不同的燃料增加周期，燃料供给量逐步增加，这两者都取决于在各燃料增加时间点由燃烧器产生的热量。 在灭火时，燃料供给量和空气供给量都分别减小到给定值，并且在给定时间段内保持在给定值。 在经过给定时间段之后，燃料供给量减少到零，同时空气供给量在给定时间段内保持在给定值。 空气供给量相对于燃料供给量的变化以给定的时间延迟而变化。 可以根据燃烧器中的温度来调整时间延迟。

摘要： A blower includes a fan that causes momentum to air by rotation, a shaft that defines a rotation axis of the fan, a bearing that supports the shaft outside of the fan, and a weight that is movable in a direction of rotation of the fan. In the fan, the weight is located opposite to the bearing with respect to an end of the fan adjacent to the bearing, and thus an increase in weight by the weight can be reduced.
