Title: Method for removing radioactive element from metallic silicon
Inventor: SHIOBARA TOSHIO
IPC: C01B33/037
Filed: 1990-07-06
Abstract: PURPOSE:To obtain high purity metallic silicon powder having a specified uranium and thorium content or below at a low cost by washing metallic silicon powder with an aq. mineral acid soln. CONSTITUTION:Metallic silicon powder having >=99.5% silicon content is previously pulverized with a ball mill, an impact pulverizer, etc., so as to enhance the washing effect of an aq. mineral acid soln. The powder is preferably pulverized to <=200mum particle size and 5-50mum average particle size, especially <=150mum particle size and 10-30mum average particle size. The resulting powder is washed with the aq. mineral acid soln. such as an aq. soln. of suluric acid, hydrochloric acid or nitric acid, preferably nitric acid. The desired concn. of the mineral acid is 0.1-5N. The amt. of radioactive elements in the metallic silicon powder can be reduced to <=1ppb within 1-20 hr reaction time. This reaction time depends on the temp. of the soln. and the purity of the powder.

Title: Robot control device provided with robot back executing function
Inventor: ITO TAKAYUKI
IPC: G05B19/4067
Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To provide a robot control device with a back executing function capable of considering also such operation related to the I/O of an external signal as to open/ close a hand or a spot gun. SOLUTION: At the time of executing the forward operation of an operation program, the type of an instruction, an objective line number, the operation position of a robot, the state of an I/O signal before the execution of an instruction, and a value before the execution of an arithmetic instruction are stored as execution history data. At the time of executing backward operation, data written in an execution history table are read out in the backward direction, the type of the instruction is discriminated (S21 to S24) and backward execution processing is executed in accordance with the discriminated result (S25 to S29). As to a backward-only instruction, an additionally teached backward-only instruction is read out and executed. As to an operation instruction, the robot is moved to a stored position.  An I/O instruction automatically inverts or individually sets up an I/O signal in accordance with set contents (valid/invalid) related to the inversion specification of the I/O signal. In the case of an arithmetic instruction, a stored unchanged value is outputted. In the case of other instructions, the program goes to succeeding processing without executing any operation.

Title: Doppler control channel for radar
Inventor: JIMII AZUBERII
IPC: G01S13/931
Filed: 1990-07-06
Abstract: PURPOSE: To improve safety by providing a device to select one of a plurality of targets while monitoring a return echo signal from the one target. CONSTITUTION: The tuning band pass frequency of SBPF gives an output frequency of VFC538 divided by 256 'S8' and serves as frequency of SBPF clock S9. When a PLL is fixed on one of a large number of frequencies developed at a Doppler channel 'S', the frequency is selected and maintained in a range channel 'T2U2". These frequencies generate radar echoes from a large number of targets, signal echoes returned through a number of paths and an echo from a reflecting object which is too far to be a target of interest. When a phase fixed loop error voltage 'S6' is down to zero, it also indicates a phase fixed condition BB3'. At this point, the frequency output is stabilized to 'S9' 128 times a Doppler frequency 'S2'.
