Title: Radar operation training apparatus
Inventor: FUJINUMA MASAKATSU
IPC: G01S7/36
Filed: 1990-01-25
Abstract: PURPOSE:To simulate the depression effect of a side lobe by separating and combining the output of a main lobe pattern function generator with the output of a side lobe pattern function generator together. CONSTITUTION:When an operator does not select the operation of a side lobe canceler on an operation display 9, the coefficient alpha of gain coefficient multipliers 73a and 73b is equal to 1 and the output of side lobe pattern function generators 72a and 72b is combined as it is with the output of main lobe pattern function generators 71a and 71b, respectively. When the operation of the side lobe canceler is selected on the display 9, since the coefficient alpha of the multipliers 73a and 73b is equal to 0, only the output of the generators 71a and 71b remains. Therefore, only main lobe patterns in the output video signals of wave propagation modulators 6a and 6b are modulated by antenna lobe modulators 7a and 7b, respectively. Thus, an incoming wave from a side lobe direction, if any, does not constitute simulated video output and the operation of the side lobe canceler is performed.

Title: Method for synthesizing diamond in vapor phase
Inventor: TANABE KEIICHIRO
IPC: C23C16/453
Filed: 1989-01-24
Abstract: PURPOSE:To inexpensively and stably synthesize diamond at a high rate for a long time by specifying the humidity of the synthesis atmosphere in the method in which diamond is synthesized on a substrate by using the reducing atmosphere of a combustion flame obtained by burning a combustible gas with a combustion supporting gas. CONSTITUTION:A combustible gas (e.g. acetylene) is burned by a combustion supporting gas (oxygen). The reducing atmosphere of the obtained combustion flame is used to synthesize diamond on the substrate (obtained by polishing the surface of a single crystal Si with diamond powder). In this case, the humidity of the synthesis atmosphere is controlled to 35-80%. Namely, steam is added to the synthesis atmosphere as mist by ultrasonic vibrator as shown in the figure, or added by a resistance-heating bubbler. Evacuating equipment, a reaction vessel, etc., are not needed unlike the conventional vapor-phase synthesis device. Moreover, synthesis can be stably performed for a long time by controlling the humidity with an inexpensive device, and the reproducibility in the crystallinity of diamond is improved.

Title: Dc high voltage generator
Inventor: NAKADA YASUHIRO
IPC: G03G21/00
Filed: 1996-01-08
Abstract: PROBLEM TO BE SOLVED: To enhance the reliability while simplifying the constitution and suppressing power consumption by comparing a value corresponding to a high voltage output with a preset constant value and then turning a drive signal on/off based on the comparison results so that the high voltage output is sustained at a constant level. SOLUTION: A transistor 2 is turned on/off depending on the outputs from an oscillator 1 and a comparator 4. When the transistor 2 is turned on, a current flows through a high voltage transformer 3 to induce a voltage corresponding to the number of turns of winding on the high voltage side. When the high output voltage exceeds a control target, i.e., a predetermined voltage, the comparator 4 functions to turn off the transistor 2 and since no current flows through the winding of high voltage transformer 3, the output voltage decreases. Consequently, the transistor 2 is turned on depending on the signal of drive pulse and the output voltage is increased again and controlled at the predetermined level. Since a transistor for regulating the high voltage level can be eliminated, the constitution is simplified while suppressing power consumption and the reliability is enhanced.
