Title: Digital voltage controlled oscillator
Inventor: FUJIWARA MOTOKI
IPC: H03L7/099
Filed: 1986-09-26
Abstract: PURPOSE:To contrive to expand the operating range by providing a fixed value generator, an adder and a frequency divider so as to control the oscillation by an input digital value. CONSTITUTION:When a digital value of a control voltage enters a complement device 10, the digital value is converted into a complement of the said digital value. This is because the oscillation frequency is increased when the digital control voltage is large through the reduction of a load value and the oscillation frequency is lowered when the voltage is decreased through the increased load value. The complementary value obtained by the device 10 is given to an adder 12 together with a fixed digital value outputted from the fixed value generator 11 and the two digital values are added. Then the sum is inputted to a frequency divider 13 as the load value. The frequency division ratio is decided by the load value in the frequency divider 13, which frequency-divides the fixed clock to attain the oscillation.

Title: Method and device for display of curve feature value
Inventor: HARASHIMA ICHIRO
IPC: G06T15/00
Filed: 1991-09-09
Abstract: PURPOSE:To cubically grasp a three-dimensional space curve with use of a conventional two-dimensional display device and without using any special device for the cubical vision. CONSTITUTION:A three-dimensional space curve 11 inputted to a computer is converted into a cubic shape (tube) 12 having its radius defined by the feature value of the curve 11. The tube 12 is mapped on the curve 11 and displayed by a display device 10. Therefore the radius of the tube 12 is increased at an area where the radius of curvature of the curve 11 is large, i.e., the bending degree of the curve 11 is small. On the contrary, the radius of the tube 12 is reduced at an area where the radius of curvature of the curve 11 is small respectively. When the curve 11 is twisted, the radius of the tube 12 is not changed in this relevant display method and in a certain viewing direction. Therefore the radius of the tube 12 shows a fixed multiple as much as the radius of curvature even though all vectors are not included in the same plane. As a result, a correct radius of curvature is shown even with a twisted three- dimensional space curve in a tube display mode.

Title: Method of removing iodine from solution in which spent fuel is dissolved
Inventor: SAKURAI TSUTOMU
IPC: G21F9/08
Filed: 1992-07-15
Abstract: PURPOSE:To remove iodine by adding iodate into a solution which is then heated up to a temperature around its boiling point, and then by heating the same at a temperature around the boiling point while feeding NOx thereto. CONSTITUTION:Since a main chemical species of iodine in a solution in which spent fuel is dissolved, is a colloid of refractory iodide, when colloidal iodine is heated up to a temperature of about 100deg.C, in a condition in which no NOx is present, in a nitric acid solution, it is decomposed into monomer iodine (I2), and is evaporated from the solution. If excessive nonradioactive iodine is previously added in the solution, the decomposing speed is successively increased. Incidentally, since a small quantity of iodate (nonvolatile) is produced together with I2, NOx is blown into the solution in order to remove the iodate. For example, NO2 is blown into the solution for 2 hours, and after the blowing is stopped, excessive IO3<-> is added to the solution which is then heated. Accordingly, the colloidal iodine 2 is rapidly decomposed, and then, when NO2 is fed at the next stage, the Iodine 1 in the solution is remarkably redced.

Filed: 1985-10-14
Abstract: PURPOSE:To obtain a photodetector having preferable frequency responding characteristic by forming a recessed part by ion beam etching on a portion formed with a pair of ohmic electrodes formed on the light absorbing layer. CONSTITUTION:Electrode pattern of AuGeNi is formed by a lifting off method on a wafer in which InGaAs light absorbing layer 12 is grown by 3mum by a halide vapor-phase growing method on a semi-insulating InP substrate 11, and a pair of ohmic electrodes 13a, 13b are formed by heat treating in H2 atmosphere.

Eventually, the photoresist is removed by ashing by oxygen plasma as a photodetector. The thus obtained photodetector is suppressed in the abnormal increase in the gain in a low frequency decrease due to a surface level caused by the deterioration of the etched surface by dry etching.

Abstract: PROBLEM TO BE SOLVED: To provide an inter-LAN connecting method whereby inter-LEC(LAN emulation client) direct communication is executed between different ELANs(emulated LAN) without the intermediary of router. SOLUTION: The inter-LAN connecting method comprises two steps. In a step 1, connection is executed between LAN emulation servers(LES) mainly for correspondence from a MAC(media access control) address to an ATM address in respective ELANs being a LAN by LAN emulation through the use of le arp(LE ARP) transfer VCC being a protocol for inquiring the ATM address from the MAC address in a LAN emulation(LANE) protocol for operating a pre-existing LAN application in an ATM network and operating a pre- existing network in the ATM network. In the step 2, LESs transfer an LE ARP request as against LEC except the one inside self ELAN to LES of another ELAN when it receives the request from LEC being an end user terminal.

Title: Solid-state image pickup element and its manufacturing method
Inventor: MORI HIROYUKI
IPC: H04N5/335
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To reduce the occurrence of white defects and, at the same time, to eliminate the occurrence of smears by covering the sensor section of a solid- state image pickup element with a silicon nitride film and providing an opening through a metallic light-shielding film on the sensor section. SOLUTION: An interlayer insulating film 18 is formed, so that the film 18 can cover a sensor section 12 and a gate insulating film 16. A silicon nitride film 19 and a metallic light-shielding film 20 are successively formed on the insulating film 18, and an opening 21 is formed through the light-shielding film 20 above the sensor section 12. Since the sensor section 12 is coated with the silicon nitride film 19, the boundary between a silicon substrate 11 and the gate-insulating film 16 and the inside of the substrate 11 are hardly damaged and, accordingly, the occurrence of white defects is reduced. In addition, the height of film 20 from the surface of the sensor section 12 becomes such that it does not allow oblique light to directly reach a transferring section 14 through the insulating film 18.  Therefore, the occurrence of white defects can be reduced without worsening the smear.
