Title: Detector for x-ray ct
Inventor: AKAI YOSHIMI
IPC: G01T1/20
Filed: 1986-05-15
Abstract: PURPOSE:To obtain a light and inexpensive detector with limited noise, by taking out signal electric charges equivalent to X-ray irradiation time, with which a capacitor is charged, as voltage mode through a voltage follower. CONSTITUTION:A photodiode 11 is combined with a scintillator and a capacitor 12 is connected in parallel thereto. The capacitor 12 is charged with signal charges equivalent to X-ray irradiation time and a voltage follower 13 outputs these signal electric charges as a voltage mode. The voltage follower 13 is controlled with switching elements 14 and 15 consisting of a MOS-FET. In other words, when an X-ray irradiation is done with the elements 14 and 15 OFF, a current generated in the photodiode 11 charges the capacitor 12 as an input impedance of the voltage follower 13 is regarded as infinite. Then, when the element 15 is turned ON after a specified period, the amount of electric charges transmitted during this period is read out through the voltage follower 13. Furthermore, when the element 14 is turned ON, the electric charge of the capacitor 12 is discharged. Thus, a scan data is collected by repeating this operation.

Title: Error generating circuit
Inventor: HIROSE KUNIHARU
IPC: H04L69/40
Filed: 1984-05-31
Abstract: PURPOSE:To generates an error very at random even in an area where an error rate is low by correlating an input digital signal with a PN pattern, and inserting the error the input digital signal according to the correlation output. CONSTITUTION:A generators 24 for a PN pattern of (n)th degree generates (n) phases of PN patterns having a period 2<n>-1 period with an input clock and supplies them to a correlation detector 25. The detector 25 detects mutual correlations between the (n) phases of PN patterns and an input signal and sends a correlation output to an error inserting circuit 26. The circuit 26 inverts the polarity of the input signal and outputs it to insert an error only when the correlation output from the detector 15 exists, and passes the input signal as it is when not. The input signal is generally irrelevant to the PN patterns, so the detector detects the correlation between the both to obtain random patterns, generating random errors.

Abstract: PURPOSE:To make a swing arm vertically movable without hardly changing the path length of a braided wire by providing a guide roller on the rotation shaft of the swing arm, and making the braided wire of a lower bobbin be contacted in the vicinity of the center of the rotation shaft to be bent to be fed to the arm tip. CONSTITUTION:The rotation of a rotary table 1 vertically moves a cam pin 32 along the cam groove of a cam wall C to rotate a swing arm 3 with a rotation shaft 31 as a center. A guide roller 8 is provided on the rotation shaft 31, and a bobbin thread H1 fed from a lower bobbin B2 is made to be contacted with a contact P with roller 8 to be bent to feed the bobbin thread H1 to the tip part of the arm 3. Since the roller 8 contacts the bobbin thread H1 in the vicinity of the center of the shaft 31, the contact P is hardly moved even the arm 3 is swung. The change of the jamb angle of the bobbin thread H1 to the roller 8 is offset by the change of the movement of the roller 8. Consequently the path length of a braided wire is hardly changed to prevent the distortion or disconnection etc., of the braided wire.

IPC: B29C65/52
Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To continuously and stably form an adhesive layer of uniform thickness by dropping an adhesive on a first disk on a table, dropping a second disk, mounting an annular weight when the adhesive reaches the outer peripheral groove by rotation, and rotating the disks at a high speed. SOLUTION: A first single disk single plate 4 is fixed by sucking with vacuum sucking holes 3a, 3b on a spinner table 2. Then the disk is rotated twice at a low speed while a UV-curing adhesive is dropped in an annular region. The rotation is stopped and a second disk single plate 4 is dropped while maintaining in a horizontal state. The UV-curing adhesive spreads to the inner and outer directions of the disks by the weight of the disk. When the adhesive reaches the stamper holder grooves 4a, 5a, an annular weight 7 is mounted and the table is rotated at a high speed. Therefore, the UV-curing adhesive interposed between the two disks is spun to the outside and an excess adhesive is squeezed out to the outer peripheral edge, thereby producing an adhesive layer having uniform film thickness on the signal plane continuously and stably.
