Title: Zoom lens structural body
Inventor: ISHIKAWA KAZUO
IPC: G02B7/08
Filed: 1979-10-12
Abstract: PURPOSE: To surely prevent the errors produced in the spacing between a variable power lens and a correcting lens by aligning the pin position of a variable power lens moving ring to its direction at the telephoto end.  
     CONSTITUTION: In the case of manual zooming, a zoom ring 6 is turned in the arrow A direction. When it abuts on the telephoto end, an oblong groove 8d 1 ' receives the force of P 1 ' by a connecting pin 24 and receives the reaction in the P 2 ' direction by the load of a gear; hence the component of force P' acts in the direction shown by an arrow. In the case of electric power zoom, a gear 18 rotates and the gear 8a meshed with this receives force in the direction of Q 1 ' and becomes load. Since an oblong groove part 8d 2 ' making pressure contact with a room ring 6 receives the reaction in the Q 2 ' direction, the cam ring 8 receives the component of force in the arrow Q' direction and moves. In this way, the components of force acts in the same direction, and direct to the direction of the pin 27 of the variable power lens moving ring; therefore, even if the cam ring 8 moves, the cam groove 8b does not give any influence upon the pin 27. Hence, producing of errors in the spacing between the variable power lens and the correcting lens are prevented.

Title: Rotation angle difference detecting device between pictures
Inventor: IWASE HIROMICHI
IPC: G06T7/00
Filed: 1983-07-19
Abstract: PURPOSE:To obtain the rotation angle difference between the same or analogous two pictures by comparing the histogram of angle of the direction of density change of two pictures while shifting relatively in the direction of each angle axis. CONSTITUTION:A buffer 2a reads the content of a picture memory 1a and stores the successively the density value of picture elements for two lines and the density value of three picture elements. Difference calculating circuits 3a, 4a, an angle calculating circuit 5a and a memory 6a constitute a histogram generating circuit, and the angle of the direction of density change in which the density of the picture in the memory 1a changes from light to shade or from shade to light is derived for each picture element and stored in the memory 6a. The same result is derived at a picture memory 1b side. A comparator circuit 7 compares respective histograms stored in the memories 6a and 6b shifting them relatively to the direction of angle axis, and determines an amount of shift when the difference between two histograms becomes minimum. Thus, the difference of rotation angle between two pictures can be determined in a short time.

Title: Walter mirror stage
Inventor: KAMITAKA NORIAKI
IPC: G21K1/06
Filed: 1994-06-14
Abstract: PURPOSE:To facilitate alignment motion by letting the rotation center axis of a Walter mirror pass in between the center point of X-ray inlet and the mirror focus on the sample arrangement side or in the vicinity of both points. CONSTITUTION:A rotational stage 201 rotates around a rotation center axis 203 in a specified angle range and a goniostage 202 swings to the center of a swing center axis 204 on the rotation part 201a of the stage 201. A holding part 205 is fixed on the swing part 202a and holds a Walter mirror 207 in a specified direction. The center axis 300' of the mirror 207 and the center axes 203 and 204 are so constituted as to cross at nearly the center of the X-ray inlet 13 of the mirror 207. If one of the stages 201 and 202 is moved to vary the inclination of the center axis 300 of the mirror 300', the central point of the X-ray inlet 103 hardly moves. By this, alignment motion becomes easy. Also, by roughly adjusting the cross point of the center axes 203 and 204 to the focus point of the mirror 201 in the sample side, the same effect is obtained.

Title: Image recorder
Inventor: HIRAOKA SATOSHI
IPC: H04N1/21
Filed: 1989-05-25
Abstract: PURPOSE:To clearly record a partial segmentation even though plural parts are recorded and outputted and without increasing the constitution by outputting the break paper for each end of recording equivalent to all pages. CONSTITUTION:A record controller 30 takes the number of originals (data E) out of a storage means 1 at start of a recording operation and loads the data E to a counter 41. Then the controller 30 takes out the picture data and at the same time revolves a motor 39 to draw in the recording paper 32. When a sensor 40 detects the arrival of the paper 32 and the counter 41 is counted down, the controller 30 controls a print head 42 based on the picture data to start the recording operation when a prescribed time passed. When a recording operation is through based on the picture data on a first original, the motor 39 is controlled again to draw in the paper 32. Then the same recording operation is carried out. When all pages are recorded, the counter 41 is reset to zero and applies an output signal to the controller 30. Thus the controller 30 controls the motor 39 to output the white paper 32 without recording it. As a result, the segmentation of the original comes to clear.

IPC: F16D55/224
Filed: 1977-11-02
Abstract: PURPOSE: Floating caliper type disc brake without unsliding trouble about a caliper due to rusting, without deformation of the bracket due to rotating of the pin at braking.  
     CONSTITUTION: If the advance rotating direction is on the arrow direction, the braking force works to the right arm 18a of the fixed support 18, since a pin section 19 is provided to this arm 18 in a body, the pitch between the pin section 19' fixed on the left section 18a and it will incrase. However since the saddle 12a on the end of the bracket 12 is cut off from outer direction and its sectional shape is nearly C-shaped to open to the rotating direction of the rotor, the pin section 19 is only away from the suddle 12a, and the braking force does not work to the bracket 12.

Filed: 1978-10-26
Abstract: PURPOSE: To accomplish safe mounting and alighting of passengers by driving a lift base made up of a retaining frame and a horizontal frame and a vertical frame arranged in the retaining frame on the floor of the vehicle.  
     CONSTITUTION: When the lift base 4 is lowered, upon the energization of a solenoid SL 1 , a solenoid valve 16 switches the passage to cause the piston rod 8 of a cylinder 6 to reciprocate. Thus the horizontal frame 2 advances along the retianing frame 1. Upon the end of the advance action, a cylinder 7 of the vertical reciprocates the piston rod 9 thereof with a sequence valve 18 to lower the lift base 4 and following the contact of the lift base 4 on the ground, a relief valve 20 is actuated to retain the lift base at the lowering position. Under such a condition, upon the energization of a solenoid SL 2  after the mounting of wheel chair users or loading, the solenoid valve 16 is switched so that the lift base 4 is actuated to rise.

Abstract: PURPOSE:To obtain a highly efficient metal vapor discharge tube having a good insulating effect in any lighting position by providing a cylindrical phototransmissive coating body covering the whole luminous tube while closing one end of said coating body and opening the other end. CONSTITUTION:In a cylindrical phototransmissive coating body 8 made of quarz glass, its upper end is softened by heating for being bent inwardly, while the space between said bent part 8a and a lead wire 9 is almost closed. On the other hand, the lower end of the coating body 8 extends below the lower end of the sealing part G of an electrode 2b, wile its end part is opened. That is to say that the coating body 8 is so constituted as to cover the whole luminous tube 1. When said discharge lamp is lighted holding the lamp base 4 upward, nitrogen inside the coating body 8 almost does not flow because the upper end of the coating body is almost closed, while an insulating effect of the lower part of the luminous tube 1 is improved for improving lamp efficiency. Further, when lighting also horizontally and slantly, the vicinity of the electrodes 2a and 2b is not directly exposed to the convection of nitrogen thus improving lamp efficiency.
