Title: Washing device for ball screw
Inventor: WATABE TAKESHI
IPC: F16H25/24
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To perform reliable removal of microforeign matter, such as dust, adhered to the male screw of a ball screw. SOLUTION: A ball screw 100 is formed such that a male screw 101 is provided with nuts 102 and 103. The annular part 201 of a washing device 200 is arranged in a state to cover the outer periphery of the male screw 101 and a female screw part 202 formed in an inner periphery is joined in a screwed-in state with the male screw 101 through a small gap. When lubrication oil is fed with a pressure through an oil pipe 250 to a feed oil passage 204, the lubrication oil is injected from a nozzle 204a through a cavity 203 toward the male screw 101. This constitution washes out dust adhered to the male screw 101. Thereafter, lubrication oil is recovered in a discharge oil passage 205 and discharged therefrom.  When lubrication oil is reliably discharged, air is fed through an air passage 206 and an annular groove 207 after a flow of it through an air pipe 251 and sprayed against the male screw 101. Further, by keeping the lubrication oil in a cooled state, cooling is also simultaneously carried out.

On the other hand, an annular permanent magnet 19A is disposed on the rear surface of the cylindrical target 13 in such a manner that the magnetic fluxes 20A leak to the front surface of the cylindrical target 13. The sputtering is executed by forming the high-density plasma in this way. The fast secondary electrons (gamma electrons) are released from the target surface and move at a high speed to the other target in this way. The discharge is stably sustained even by the low gaseous pressure and the high-density plasma is stabilized.

For diagnosis of an ECC circuit, the diagnosis data are written successively into the addresses at the MD part of the unit 11 through the input data line 1. At the same time, the Hamming bit is also written into the MH part. Then the error data corresponding to the case an error occurs is supplied to the address FF. The error data is held in the register 13 by the control signal 20, and the addresses OO-FF are read successively. Then the Hamming bits are set successiely to the register 15 to be compared with the register 13. Thus a diagnosis is given to the ECC circuit.

Filed: 1996-06-17
Abstract: PROBLEM TO BE SOLVED: To produce a package in which a tablet is securely contained, by pressing the top of a swelled part for containing the tablet to the cover film side and removing the tablet package when the pushing-down depth becomes larger than a specified value. SOLUTION: A cover film 3 made of aluminum foil is bonded on a containing film 1 having a low vapor-permeability and a high light-blocking property to form a containing space S for a tablet 2. The top 1t of the swelled part 1a of the film 1 is pressed with a specified load toward the cover film side by a pressing pin 21. In this time, when a tablet 2 is contained in the space S, since the load of the pin 21 can be supported by the tablet 2, the swelled part does not break and keep a certain height. That is, the pressing-down depth (p) becomes smaller than a specified value. Accordingly, the package lacking in a tablet can be removed by discriminating the pushing-down depth (p) of the pin 21.

Title: Plate type picture display device
Inventor: TSURUKI TAKAYUKI
IPC: H04N9/16
Filed: 1988-06-23
Abstract: PURPOSE:To eliminate the sensibleness of a joint in a band caused by the difference in the way of the occurrence of an error in reproducing a color by inverting the arrangement of fluorescent substances in the interval between adjacent band blocks and making the relation between a deflecting direction and the application arrangement of the fluorescent substances the same in each band block. CONSTITUTION:When an applying order of fluorescent substances (a)s is the same, the joint between the band blocks comes up to the surface because of the structure of a plate type picture display device. In order to prevent the coming up of the joint, the arrangement of the fluorescent substances (a)s is inverted in each interval between the band blocks. Thus, in each band block, the relation between the deflecting direction of an electron beam and the applying order for the respective fluorescent substances can be the same. As the result, for example, when the deflecting direction dislocates toward a red fluorescent substance in a certain band block, the error in reproducing the color to occur in each band block occurs in the intervals between the applicable band block and its adjacent band block in the approximately same manner. Namely, the joint between the band blocks caused by the difference in the error in reproducing the color, which occurs because of the difference in the deflecting direction, can be made less sensible.
