Title: Reducing method of volume of chopped piece of spent fuel
Inventor: OBA SHINSUKE
IPC: G21F9/30
Filed: 1990-02-06
Abstract: PURPOSE:To improve the rate of reduction of volume and to reduce the cost for disposal of chopped pieces of spent fuel by a method wherein the chopped pieces of the fuel are exposed to an arc discharge of high-voltage and high- current plasma in water, heated to a high temperature and made to react with the water and water vapor. CONSTITUTION:Chopped pieces 1 of fuel subjected to compression molding are put on a frame 2 in an underwater discharge treatment vessel 7 and disposed between two electrodes 3. Next, water is sent into the vessel 7 from a water supply pipe 9, and after the chopped pieces 1 are covered sufficiently with the water, a discharge of high voltage and high current is generated between the two electrodes 3 and the chopped pieces 1 by operating a discharge power source 5. By this discharge, the chopped pieces 1 are heated instantaneously and turn to be zirconium oxide powder in the chemical reaction with the water, generating hydrogen simultaneously. This hydrogen is introduced into a hydrogen refining device 11 through a reaction gas discharge pipe 10 and it is caught in a hydrogen collecting vessel 13. The oxide zirconium powder produced in the vessel 7 is collected after the underwater discharge treatment and stored in a hermatically sealed vessel made of metal.

Title: Positioning method for building berth
Inventor: IIZUKA TADASHI
IPC: G01S5/16
Filed: 1985-02-14
Abstract: PURPOSE:To reduce the cost of a device by measuring the position of a building berth by using one automatic tracking light-wave range finder and one automatic tracking light wave range finder goniometer. CONSTITUTION:A reference light source device which has a corner prism and a light source is installed at reference points A and B at both end of the base line l0 of a land part. Then, the automatic tracking light-wave range finder is installed at a reference point C on a building berth. Then, a light-wave range finder tracks the directions of the corner prisms at any time even if the building berth fluctuates or moves owing to the flow of sea water. AT this time, the automatic tracking light-wave range finder at the point C measures the distance l1 between the points A and B automatically at any time and output data. Further, the automatic tracking range finder goniometer at a reference point (d) collimates the point C on the building berth previously to set an angle display to zero, and then collimates the reference point B on the land automatically to measure the opposite side distance l2 and angle theta. Consequently, the building berth can be positioned. This device is reduced in manufacture cost because the system is simplified.

IPC: G06G7/163
Filed: 1978-03-08
Abstract: PURPOSE:To ensure the offset for the nonlinearity error for two units of the transconductance by giving the parallel connection to one side of the input terminal and then giving subtraction to two units of the output given in the different polarities for the other side. CONSTITUTION:Transconductance operational amplifier 3 and 4, which feature the same linearity error of conductance, are selected. The multiplication output of the input of amplifier 3 and bias input 2 given via positive-negative converter 5 is supplied to operational amplifier 6 along with the multiplication output of the input of amplifier 4 and bias input 2. And the signal output obtained by reversing the multiplication output of amplifier 3 is delivered through terminal 7 along with the multiplication output of amplifier 4 which received addition via amplifier 6. Thus, the error can be offset by adding the input the error directions of which are quite opposite to each other through amplifier 6, and accordingly the error caused by the nonlinearity of the transconductance amplifier can be reduced.
