Title: Hologram scanner
Inventor: YAMAZAKI KOUZOU
IPC: G02B26/10
Filed: 1983-11-29
Abstract: PURPOSE:To separate an incident beam and convergent light without using any light separating element such as a holed mirror by forming a scanning and a converging area with different reference waves. CONSTITUTION:A laser light source 20 and a beam expander 21 are so arranged that the incident beam 22 which is converged on one point P on the center axis of a hologram disk 23 through the scanning area 25 of a hologram 24 is projected. A lens 31 which guides convergent light 30 generated by converging signal light 29 reflected by a body 28 to be read in the converging area 26 of the hologram 24 and a photodetector 32 are arranged in parallel to the center axis of the hologram disk. The scanning area 25 is irradiated with a spherical wave 36 which converges on a point P on the axis of rotation of the disk 23 and the converging area 26 is irradiated with a vertical plane wave 37. Both areas are formed by using the same spherical wave as an object wave, so reproduced light is converged on the same point P'. Thus, the scanning area and converging area are formed with difference reference waves to separate the incident beam and convergent light and also reduce the size and cost of the device.

Title: Address conversion system
Inventor: YOSHIHARA IKUO
IPC: G06F12/04
Filed: 1986-09-24
Abstract: PURPOSE:To give accesses to blocks set with unequal spaces by sampling partial columns smaller than the number of words of a CAM array and deciding the section of a specific partial column that includes the search data. CONSTITUTION:A search data register 1 stores an address l of the data displayed in a 1-dimensional form. A CAM array 2 serves as an associative memory having word length W and stores the key data n'k on plural partial columns {(nk')}. Then the array 2 compares the data n'k with the address and returns '0' when the data n'k is smaller than the address l and then '1' vice versa. A priority encoder 3 delivers the minimum number among those having answers '1' of the array 2. A block data register 4 stores a block number nk, the number (k) of data and the deciding frequency M. A data selector 6 extracts a designated partial column out of a partial column {nk} and outputs a block number (k) when the search is through. Thus it is possible to shorten the searching time and to decrease the number of CAM words.

Filed: 1982-12-22
Abstract: PURPOSE:To attain higher di/dt and peak current as an off-gate current of a gate turn-off thyristor GTO and to avoid the gate loss from being increased by providing the 3rd winding and a switching element to the primary side of a pulse transformer. CONSTITUTION:When a TR19 is turned on, a voltage Ec is applied between terminals B and D and a potential at a point A reaches Ec(1+N1/N3), where N1, N3 are the number of turns of windings 151, 153. Thus, no current flows to a diode 12 from a power supply 11. In this case, a voltage of Ec/n2 (where n2 is the winding ratio of windings 153 and 16) appears in the winding 16 and a capacitor C starts discharge in the time constant tau1=C.R3.n<2>2, where R3 is the resistance value of a load 18 and C is the capacitance of a capacitor 13. In turning off the TR19 and turning on a TR17 at a time t1 during discharge, the discharge time constant of the C is changed over into C.R.n<2>1 (where; n1 is the winding ratio of the windings 151 and 16). When a voltage across the capacitor 13 reaches E2, the potential at a point A becomes E and when the voltage is decreased further, a diode 12 is conductive.
