IPC: G11B7/004
Filed: 1981-11-27
Abstract: PURPOSE:To detect a rotation starting position mark signal truly and stably even with flaws and dust attached, by controlling a disc motor with the mark signal as a reference signal. CONSTITUTION:When the rotation of a disc motor 12 is controlled to a constant value and address information (j) is read, a control circuit 11 gives a signal (i) being ''H'' and ''L'' in other cases, respectively. The address information (j) from an address processing circuit 10 is inputted to a multivibrator 25. The multivibrator 25 converts D the address information (j) into a consecutive pulse as a time constant slower than the frequency of the (j) and inputs the result to a low-pass filter 26. The low-pass filter 26 eliminates one pulse not consecutive such as dropout due to dust and flaw and inputs it to a comparator 27.

Abstract: PURPOSE:To reduce the splash of rain water and prevent same from hitting on the side of a structure to prevent the structure from being stained by forming the captioned eaves gutter in such a way that the rain water fallen from the end of a roof material or a drip board does not directly hit on a water surface but hit on the bottom portion of the eaves gutter. CONSTITUTION:An eaves gutter A consisting of a bottom portion 1, a front-side side wall 2, a rear-side side wall 3, a front side rib 6 and a rear side rib 7, etc. is installed to a fascia board 10 by means of a supporting member B in such a way that the rear side rib 7 is positioned on the lower portion of a drip board 13 and that the side wall 3 is close to the drip board 13 while being separated from the fascia board 10 as far as possible. Rain water which falls down along the drip board 13 does not hit on the water surface of rain water flowing in the deepest place of the bottom portion 1 but hits on the rib 7 and is splashed up toward the front on the opposite side to the fascia board 10. Thereby, the height of splash can be lower than that at the time of fitting on the water surface and the rain water which is splashed forward can prevent the side of a structure from being stained.

Title: Image reader
Inventor: INOUE TOSHIYUKI
IPC: G06T1/00
Filed: 1998-07-07
Abstract: PROBLEM TO BE SOLVED: To provide an image reader capable of obtaining the image data of high quality. SOLUTION: The axial direction (direction of the arrow Z) of the winding wire 132A of the filament 132 of a halogen lamp 32 matches with the main scanning direction (direction of the arrow X) of a line sensor 116. Thus, when incidence is performed from the halogen lamp 32 through the read part of a photo film to the line sensor 116, the difference between the light quantity of the center part and both end parts of the line sensor 116 is minimized in the main scanning direction. As a result, light quantity irregularities in the main scanning direction of light made incident on the line sensor 116 are reduced and the image data of the high quality are obtained.

Title: Sample holder for scanning tunneling microscope
Inventor: AMAKUSA TAKAAKI
IPC: G01N37/00
Filed: 1994-08-17
Abstract: PURPOSE:To enable observation of various heated STM images through the removal of adsorbates on sample surfaces by enabling a sample and its surroundings to be cooled via a heat conducting member and a holder cooling member, and enabling the sample to be heated via a current-carrying terminal. CONSTITUTION:When this sample holder 1 is mounted on a cooled-sample stage, heat from a liquid helium container is transferred to a heat conducting member 7, a current-carrying terminal 5 and a sample holding member 8, and also to a holder main body 2 to cool a sample 10. When the holder 1 is mounted on the stage and rotated 45 degrees clockwise, the terminal 5 of the holder 1 comes into contact with an electrode to pass current to the sample 10 for heating. Since the main body 2 is cooled by way of a holder cooling member 11 independently of the stage, its surroundings are almost not heated. Therefore, adsorbates splashed off the sample surface by heating are substantially adsorbed to the surroundings by cryogenic effects, and the sample surface can be kept clean during re-cooling.

Title: Sliding device
Inventor: AZUMA KOUICHI
IPC: F16C33/10
Filed: 1981-11-30
Abstract: PURPOSE:To hold a viscous fluid for a long period of time and reduce age variation of the frictional resistance hy applying a viscous fluid having a lubricating effect between a stripe of a spirally recessed groove formed in the inner part of a cylindrical bearing and the shaft. CONSTITUTION:A strip of continuous recessed groove 9a is formed in a spiral shape at the inner surface of a central hole of a cylindrical bearing 9. A viscous fluid 8 having a lubricating effect such as oil, grease or the like is applied between the recessed groove 9a and the shaft 3. By this operation, since the viscous fluid 8 stays in the recessed groove 9a, the viscous fluid 8 is not removed even if the device is used for a long period of time, and hence the age variation of the friction resistance can be reduced.
