摘要:
The invention provides a method of high productivity for the preparation of a substantially dislocation-free single crystal of a compound semiconductor such as gallium arsenide by the liquid-encapsulated Czochralski method. The improvement provided by the invention comprises admixing the melt in the crucible with an additive having an equilibrium segregation coefficient K.sub.O smaller than 1.0, which is indium in the preparation of gallium arsenide single crystals, in a concentration of at least 1.0.times.10.sup.21 atoms/cm.sup.3 of the melt and rotating the crucible at an unusually high velocity of at least 40 rpm.

摘要:
A flow rate sensor having an annular passage for enabling a flow of liquid therethrough and a movable member disposed in the annular passage. An intake passage is provided for supplying liquid to the annular passage and an outlet passage, disposed concentrically to the intake passage, enables the liquid to flow out of the annular passage about an outer periphery of the intake passage.

A method and apparatus for developing an electrostatic image on an electrostatic image holding member by feeding toner particles thereto, in which a layer of the toner particles is formed on a toner carrying member, and the toner carrying member and the electrostatic image holding member are brought to a mutually closer position and maintained in such a range that the surface of a non-image section of the electrostatic image holding member and the surface of the toner particle layer on the toner carrying member may not be contacted with each other, but the surface of the toner particle layer is in contact with the surface of the image region of the electrostatic image holding member, whereby uniform development of the electrostatic image on the image holding member can be effected.

A flip-flop circuit provided with gate function is disclosed. The flip-flop circuit comprises first and second transistors whose bases and collectors are cross-coupled at first and second nodes, third and fourth transistors of which the collectors are respectively coupled to the first and second nodes, first switching means coupled in parallel with the collector and the emitter of the first transistor, and a second switching means coupled in parallel with the collector and the emitter of the fourth transistor, wherein the first and the second switching means are controlled by the same signal.

This invention relates to connecting members in a connector for use in connecting respective conductors in flexible flat cables. These connecting members have a slit in a crotch shaped structure to impart greater flexibility to the member. In addition the connecting members employ two pairs of offset tines to form a better connection with stranded cables.

To provide a motor driving system for an electrically powered automotive vehicle, in which the drive motor is rotationally controlled to increase the reliability, the use is made of an angle sensor for detecting the relative rotational angle between a stator and a rotor of a drive motor for driving the electric vehicle and a controller for controlling the rotation of the drive motor on the basis of the relative rotational angle detected by the angle sensor. The angle sensor is provided in a plural number. The controller includes an angle sensor switching unit operable to select and activate one of the plurality of the angle sensors and then to switch over to an activation of another one of the angle sensors in the event that the one of the angle sensors is determined abnormal.

Observation samples in a sample solution are held due to absorption or the like on a rear face of a first X-ray transmission film. In a mirror body, while an X-ray emission film and X-ray transmission films are bent to be convex outward due to a pressure difference, an X-ray transmission film is bent to be convex toward the X-ray transmission film side due to gas expansion in a second cavity part. This bending results in widening of a gap between the first and second X-ray transmission films in their center part more compared with a gap between their end parts. However, there is almost no change between the X-ray transmission films.

A wheel support bearing assembly includes rolling elements interposed between outer and inner members, and sensor units are fitted to one of the outer and inner members, which serves as a stationary member. Each of the sensor units includes a strain generating member, having two or more contact fixing segments fixed to the stationary member, and two or more sensors fitted to the strain generating member for detecting strains occurring in the strain generating member. The two or more contact fixing members are arranged at the same axial positions of the outer diametric surface of the stationary member in a fashion spaced in a circumferential direction. A calculating section is provided for estimating the load acting in the wheel support bearing assembly by the sum of respective output signals of the sensors.
