摘要： PURPOSE:To form a load cell stable in temperature change with low cost, by using sheet metal construction for a strain gauge type load cell. CONSTITUTION:A sheet metal which is easily obtained as a constantly elastic material, is pressed, and plates 25, 26 providing two holes 34, 35 around the center lengthwise and two fitting holes 32, 33 near one end, and a plate 27 sticked with four strain gauges 21-24 on the front and rear sides of two sectional coefficient minimum parts corresponding to the holes 34, 35 of the plates 25, 26, and provided with almost semicircular holes 36-39 leaving the center and with two fitting holes 32, 33, are prepared. Further, the plates 25, 26 are fixed on and below the plate 27 via blocks 28-31. Thus, a load cell is formed with low cost material easily, plates 25-27 are deformed in almost the same shape to a vertical load, and a strain corresponding to the load is produced to the strain gauges 21-24.

摘要： PURPOSE:To minimize a difference of postures and a driving torque by a method wherein a rotatable sleeve is engaged with a central shaft, adapted to a portable type VTR cylinder and fixed to a base plate, and a fluid lubricating bearing having stepped portions is formed between both of them. CONSTITUTION:Stepped portions are formed on a central shaft 12 at an upper and a lower positions thereof and further spiral grooves 50, 51 are formed on the stepped portions. The upper stepped portion 22 is formed so as to be located at a position opposing to internal wall portions of an upper cylinder, a head or the like while the lower stepped portion 23 is formed so as to be located at a position opposing to an internal wall of a motor magnet. Consequently, an oil reservoir 25, having an ample clearance between a rotating sleeve and the central shaft 12, is formed at an intermediate portion 24 between the upper and lower stepped portions 22, 23. According to this constitution, a bearing radial clearance value, wherein the bearing radial clearance satisfies binding conditions with respect to a difference of postures and a load torque in a VTR cylinder may be obtained. Accordingly, the difference of postures and the driving torque may be minimized.

摘要： PURPOSE:To prevent the generation of strain by thermal-expansion differences in a rotation-transmission device by providing a shaft fixed fast on a base-plate on one end and a sleeve connected to this shaft to be rotatable via a fluid lubrication bearing, and constructing the shaft of two members different in their thermal expansion coefficients. CONSTITUTION:To be applied to a cylinder mechanism of a VTR unit, this device is provided with an upper cylinder 1 equipped with a head 2 and a lower cylinder 3 fixed fast on a lower housing 4 as a base plate, while a rotary sleeve 7 as an upper housing is fixed fast to the upper cylinder 1 to be detachable. There are also provided a stator 10 and a rotor 11 for a direct-drive motor to give a rotational driving power to the rotary sleeve 7. A central shaft fixed fast to the lower housing 4 on its one end is constructed of a couple of members 12 and 13 different in thermal expansion coefficients, and the rotary sleeve 7 is fitted to the central shaft of members 12 and 13 to be rotatable with lubricating oil film between.

摘要： PURPOSE:To enable minute load to be accurately detected and improve weatherability by covering strain gauges and the strain gauge bonding parts with inert liquid in a load detector using the strain gauges. CONSTITUTION:A beam 11 has a rectangular section and formes a parallel spring with the holes 30, 31 and a notch 32 provided near its center. Strain gauges 12 are affixed to the top and bottom of the thin-walled part thereof and are put in inert liquid 18 to be cotoff from the effect of moisture, etc. When a load is applied via steel ball 16 to the end of the beam 11 by a rod 17, the beam 11 deflects and this produces strain in the strain gauges 12. This strain is detected as electric signal. The use of the inert liquid 18 of a relatively low viscosity obviates restraining of the strain gauges 12 and bean 11 thereby making it possible to obtain the sure output even for the minute load.

摘要： PROBLEM TO BE SOLVED: To effectively rotate an object to be conveyed and to reduce a thermal deformation of a roller in a roller driver for conveying the object while rotating the object. SOLUTION: The heating furnace supports a ceramic roller 11 at its one end 11a and the other end 11b by a drive roller 12 and a driven roller 13, and vertically circulates the roller 11 in a conveying direction of an object 80 to be conveyed and reverse returning direction while rotating the roller 11. Thus, the object 80 can be effectively rotated, and a thermal deformation of the roller 11 can be suppressed to small one.

摘要： PROBLEM TO BE SOLVED: To reduce the burden on an operator and improve the operability by making a power assist torque of a desired time and a desired value act on a wheel regardless of value of input torque based on an instruction by switching of a state switching means. SOLUTION: A switch as a state switching means is provided in a wheelchair for performing a power assist. As the figure shows the relation between an input torque 72 and a power assist torque 73 in a power assist method, when a switch is in an ordinary state and the input torque 72 becomes 0, the power assist torque becomes 0 and has a waveform shown by a broken line. Secondarily, when the switch is switched and changed into another state, the input torque 72 becomes smaller than the desired value and becomes 0, however, the power assist torque 73 does not becomes 0 and holds the desired value as shown by a solid line. The desired time and the desired value are set by the sensibility of an operator.

摘要： PROBLEM TO BE SOLVED: To secure airtightness by installing a ring elastic body in a space formed of a rim and a tire. SOLUTION: End parts of a rim bead 2 and a tire bead 5 respectively have protruded parts toward inside and outside, and they are constituted in dimensional shapes to be connected with each other. A rim shoulder part 3 holds a tire bead bottom part 7. A cross-sectional shape of the tire bead 5 connected to the rim bead 2 is constituted so that an interval of both sides of tire bead 5 facing against each other becomes narrower as it approaches the rim center direction, that is, a direction of a spoke installing hole. A ring elastic body 8 makes a wedge shape on its cross-section and is installed between two of the tire beads 5. Consequently, as the ring elastic body 8 is pushed in the rim center direction by air pressure, the ring elastic body 8 becomes wedge-shaped and fitted between the tire beads 5, 5, and accordingly, the tire beads 5 are pressurized on the rim bead 2 more firmly.

摘要： PURPOSE:To reduce an attitude difference due to a change in the axial part of a rotating part as much as possible by providing two thrust bearings remarkably different in the characteristic of the change of an axial thrust force to the change of a gap at both the end parts of an axia. CONSTITUTION:On the center part of one end face 9 side of a rotating shaft 1, the protruding part of a small diameter is formed. On the surface thereof, a microgroove bearing 5 on which a spiral groove is formed is provided. On the surface of a balance type spiral bearing 3, grooves for feeding lubricating oil under pressure to the center part of a housing 6 are symmetrically formed. On a thrust bearing 4, a spiral groove to a direction for feeding the lubricating oil 12 to a right end face is formed. Thereby, to the change of the axial load of the rotating shaft 1 which is produced by the attitude difference of the rotating shaft 1, the change of a position can be reduced.
