摘要： PURPOSE:To improve the sample positioning accuracy of the title device even when the size of samples increases by arranging projections for supporting a sample holding table on a rough adjustment stage side in a scattered state in a through space inside a fine adjustment stage so that the projections can be made to function as a rough adjustment stage while the through space is faced to the arrangement of the projections and the base of the rough adjustment stage is positioned below the fine adjustment stage. CONSTITUTION:This sample positioning device is provided with a rough adjustment stage 3 which is movable in two directions of X and Y axes and a fine adjustment stage 4 which is movable in three dimensions of X, Y, and Z axes and the stages 3 and 4 are not mechanically connected with each other so that they can work independently. The stage 3 is constituted of a base 3A which is supported by a rough adjustment driving mechanism 6, etc., and a plurality of projections 3B1...3Bn for supporting a sample holding table 5 arranged on the surface of the base 3A in a scattered state. Through spaces 4A1...4An are formed inside of the stage 3 in corresponding to the projections 3B1...3Bn and the projections 3B1...3Bn are arranged in the spaces 4A1...4An while the base 3A of the stage 3 is positioned below the stage 4. The stages 3 and 4 can hand over the sample holding table 5 to each other when the vertical relation between them is changed by means of a Z-axis deriving mechanism 14.

摘要： PURPOSE:To provide the above display device which withstands the various environments to which the device is subjected from a vehicle and to eliminate the need for a space to be packaged on the vehicle by providing a case which holds a back light for irradiating a liquid crystal panel from a rear and a supporting means which freely openably and closably supports a frame body and exposing the rear of the liquid crystal panel. CONSTITUTION:The frame body 1 is mounted to an internal partition wall 8 by means of supporting fittings 34 fixed to an revolving shaft 33 and an internal partition wall 8 and is constitute freely openably and closably to the case 2. The liquid crystal panel 6 is fixed to the frame body 1 and a filter 18 is fixed to the front surface thereof. On the other hand, the internal partition wall 8 is fixed to the case 2 and the back light 7 is fixed to this internal partition wall 8. If the surface of the liquid crystal panel is stuck with dirt by the dust generated in a vehicle room, the rear of the liquid crystal panel 6 is exposed by opening the case 2 and is wiped, by which the dirt is removed. The considerations to the various environments to which the display device is subjected from the vehicle and the limitation on the packaging on the vehicle are eliminated.

摘要： PURPOSE:To prevent an excessive shift of a rolling body group and a retainer, and to reduce the abrasion between respective constituting members, by providing braking mechanisms, which provide braking force to the retainer, at both ends of the retainer in which a rolling body group provided on a guide surface is retained. CONSTITUTION:On a guide surface 1, a rolling body group 3 incorporated in a retainer 2 is provided, and a moving body 4 is provided via the rolling body group 3 so as to be movable in the right and left directions. In this constitution, braking mechanisms 5 are provided at both end parts of the guide surface 1. And each of the braking mechanisms 5 is so constituted that two plate springs 55 are fitted to the end part of the guide surface 1 via a fitting part 5a, and that a pushing rod 5c is provided at the end of the plate springs 5b. Thus, when the rolling body group 3 and the retainer 2 shift In one direction to reach the end part of the guide surface 1, the end of the retainer 2 pushes the pushing rod 5c in one direction, so that respective plate springs 5 elastically deform to exert reaction to the retainer 2. Consequently, the shift of the rolling body group 3 and the retainer 2 can be restrained.

摘要： PURPOSE:To enhance positioning accuracy, by setting a diameter of a rolling element between a contact surface and a guideway so as to cause a moving body's position to be kept constant to waviness on the guideway of wavelength of more than the overall length of the guideway. CONSTITUTION:When a moving body 5 is moved by driving force of a linear motor 12, a rolling element group moves as far as one a half of travel of the moving body 5. At this time,a first rolling element 4a and a second rolling element 4b are situated in position between a first contact surface 13 of the moving body 5 and a guideway 2. And, a fourth rolling element 4d and a fifth rolling element 4e are situated in position between a second contact surface 14 of the moving body 5 and the guideway 2. At the time of movement, a guideway 2a opposite to the second contact surface 14 of the moving body 5 is more protuberant than a guideway 2b opposite to the first contact surface 13 of the moving body 5, but the mean value of each diameter of these first and second rolling elements 4a and 4b is larger than that of these fourth and fifth rolling elements 4d and 4e. With this constitution, a positional change due to wavy height variations in the moving body 5 is compensated.

摘要： PURPOSE:To attain the automatic control of a controlled system and furthermore to perform teaching and reproduction of manual operations by a memory part of smaller capacity, by storing successively the control forms of manual operations and then reproducing these stored control forms. CONSTITUTION:The control forms of manual operations are successively stored and then reproduced. An element setting process means STM decides previously a level element, an edge element or a timer element to recognize an input device. A teaching process means THM has a function to store successively the simulated operations of the controlled system carried out by an operator. A reproduction process means PBM has a function to control the controlled system in a desired state based on the storage contents of the means THM. When a basic program stored in a ROM is started, the state of a mode changeover switch M provided to a program device PGM is supplied at first. Then a mode is decided in steps 6b, 6c and 6d respectively. Then the processing is shifted to the means STM with the element setting mode, to the means THM with the teaching mode and to the means PBM with the reproduction mode respectively. Thus the prescribed processing is carried out.

摘要： PURPOSE:To enable a guide to be prevented from decreasing its straightness due to heat generation of a linear motor, by arranging the X-direction linear motor extending over two moving units on Y-guides while a Y-mover, being a constitutional element of the Y-direction linear motor, between the Y-guides. CONSTITUTION:A device, providing an X-stator 8A of an X-direction linear motor 8 extending over both moving units 3 between X-guides 5, 5, provides an X-mover 9, mounted to a table 6 through an intermediate member 10, to be arranged in said stator 8A, and the table 6 is driven in a direction X by the X-direction linear motor 8. While the device, mounting a Y-mover 12 of a Y-direction linear motor 13 to the bottom surface central part of the X-stator 8 through an intermediate member 11 and providing a Y-stator 13A between both Y-guides 2 on a fixed part 1,drives the table 6 in a direction Y through X-guides 7. In this way, the device obtains a table motion of high straightness with no decrease of straightness of the X-guides 5 even if the moving unit 3 is a little thermally deformed by heat generation of the movers 9, 12.

摘要： PURPOSE:To prevent wire breakdown, separation of a pellet and the like even at time a semiconductor device is intensely vibrated, by mounting or embedding a holding member having a specified shape on or in a coating material. CONSTITUTION:In a silicon gel 12, a net 13 comprising a metal, e.g., 42 alloy, which is a holding member bent and formed in a specified form, is embedded. The net 13 is fixed at the same time a cap 4 is attached by a bonding agent 5 at the peripheral part of the net. The peripheral part of the net 13 is fixed in this way and the inside of the net is embedded in the silicon gel 12. Therefore, the silicon gel can be held at the specified position. Even if the semiconductor device is placed in an intensely vibrating state, occurrence of breakdown of a wire 10 and the like caused by vibration and separation of the silicon gel can be prevented. Since the periphery of the net 13 is contacted with the bonding agent 5 having heat conductivity, heat generated in the pellet at the time of operation can be conducted to the cap 4 through the net 13. Thus efficient heat radiation can be achieved.
