    Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive volumetric pump capable of purging bubbles from a pump chamber, easy of accurate flow control and suitable for an IV filling set. SOLUTION: The volumetric pump comprises a slender chamber 8 inside and a housing open at one end and closed at the other end. An elastic material sheet open at the center covers the opening end. A pump shaft 60 is inserted through the opening of the sheet into the chamber to form a sphincter seal in the opening in cooperation with the sheet material. The other end extends to the outside. The opening has a cross section shape substantially the same as that of the shaft and a cross section size the same as or smaller than that thereof. A fluid inlet 36 is provided near the opening end of the housing so that fluid is supplied from a fluid source into the chamber 8. A fluid outlet 40 is provided near the closed end of the housing so that the fluid is supplied through the outlet from the chamber 8 to a fluid sink. COPYRIGHT: (C)2007,JPO&INPIT

    Abstract: PURPOSE: To provide a method and a device for carefully and closely monitoring the action of a driver, while keeping safety for the driver concerning the method and device for effectively and realistically simulating the movement of the driver. CONSTITUTION: This device is provided with a pedestal 12 and a means 80b movably fitted onto the pedestal so as to hold the feet of the driver, and the foot holding means 80b can move corresponding to the motion of feet of the driver. A resistive force generator 88 is installed and corresponding to a condition signal, resistive force is applied against the action of the foot-holding means. A display means for displaying the scenery (scene) that can be watched by the driver, corresponding to a display signal can be made into screen surrounding the driver or headgear means 140 to be worn, so as to cover the eyes of the driver. In order to change the resistive force to be applied to the foot-holding means corresponding to the displayed scene, a control unit supplies the condition signal to the resistive force generator 88. When the scene shows the topography of an up slope, for example, high resistive force is applied to the foot-holding means 80b, and the motion of the foot-holding means 80b is made much more difficult and simulated.

    Abstract: PURPOSE: To provide a compact position detector having a small number of components by transducing the proximity of a flexible band rolled in response to the movement of an object to a surface area into an electric signal. CONSTITUTION: An object 4 is mounted at one end of an extended flexible conductive band 8. The band 8 is connected to a voltage source 16 capable of generating an electric field. An FET 20 having a conductive source region 24, a conductive drain region 28 isolated from he source region and entirely formed in parallel with the source region and a conductive channel region 32 disposed between the source region and the drain region is formed on the upper surface of a base material 12. The band 8 is rolled on an insulating layer 36 to operate as the gate of the FET 20, and the current detected by a counter 38 is varied, and hence the position of the object 4 can be detected.

    Abstract: PURPOSE: To decide a distortion state in a body by a method wherein an amplitude is in proportion to a difference in a magnitude of an input signal indicating a magnitude of relative movement of a second projection portion for a first projection portion and a third projection portion, and a comparator for generating an output for deciding polarity by a movement direction of the projection portion is provided. CONSTITUTION: This operation circuit contains a voltage source 57 connected with an emitter 40 on a first projection portion 28; a voltage source 59 connected with a drain region of FET's 44, 48; and two current to voltage transducers 65, 67 connected with each source region of FET's 44, 48. Polarities of a voltage signal generated in voltage amplifiers 65, 67 are reversed, and amplitude of these signals is in proportion to a difference in a magnitude of an input signal (showing a magnitude of relative movements of projection portions 32, 36 for a projection portion 28), and these signals are supplied to a comparator 69 for generating an output signal for deciding polarity by a movement direction of the projection portion. Thereby, a magnitude of distortion in a body during measurement can be decided and it can be decided whether the distortion is in a pulling state or in a compression state.

    Abstract: PURPOSE: To provide a volumetric pump of low costs which is suitable for an IV filling set and the like wherein bubbles are cleaned up from a pump chamber and a flow rate is correctly and easily controlled. CONSTITUTION: A device has a housing provided with an elongate cavity 8 and whose one end is opened and the other end is closed. An opening end part is covered with an elastic material sheet having an opening on a center part. A pump shaft 60 is penetrated on an opening of a sheet, and is inserted into a chamber so as to form a sphincter seal in cooperation with a sheet material on the opening. The other end extends to an outside. The opening has substantially the same cross sectional surface shape as a shaft, and has the same cross sectional surface size and a cross sectional surface size smaller than it. A fluid inlet 36 is provided in the vicinity of an opening end part of the housing, and is led from a fluid source into a chamber 8. A fluid outlet 40 is arranged in the vicinity of a closing end part of the housing, and the fluid is led from the chamber 8 into a fluid sink bypassing its outlet.

    Abstract: PROBLEM TO BE SOLVED: To efficiently and accurately adjust the position and motion of an armature at a high speed with high power by appropriately arranging passive conductors on a base as passive elements and selectively controlling the position and motion of the armature relatively to the base by changing the voltage levels at the passive conductors on the base. SOLUTION: Conductor elements 40a and 40b are appropriately arranged on a base member 12 containing the sapphire substrate of an armature 20 as passive elements and the elements 40a and 40b are connected to a controller 44 through amplifiers 46a and 46b, respectively. The controller 44 selectively changes the position and motion of the armature 20 relatively to the base member 12 through the amplifiers 46a and 46b by changing the voltage levels at the elements 40a and 40b. Therefore, the position and motion of the armature 20 can be adjusted accurately and highly efficiently at a high speed with high power and a high advantage.
