Filed: 1989-03-07
Abstract: PURPOSE:To align the optical axes of waveguides with each other with high accuracy by easy operation wherein each waveguide part substrate is only made to abut on a reference surface by dividing waveguides formed on a single base body substrate into respective waveguides. CONSTITUTION:A couple of straight waveguides 15A and 15B which extend in parallel at an interval are formed on the quadrilateral base body 20 whose size is equal to the total size of respective waveguide substrates 11 - 13, and an independent curved waveguide 15C is formed outside them.

Title: Electric power converter
Inventor: KAKIYA TSUTOMU
IPC: G05F1/455
Filed: 1984-03-23
Abstract: PURPOSE:To reduce the surge voltage which is produced when a current is cut off by using an arithmetic means to calculate the 2nd reference voltage, and arc- extinguishing a switching element when the cumulative value of converter outputs reaches the 2nd reference voltage. CONSTITUTION:An operator 12 consists of a broken line approximating circuit like a converter 6 and supplies the 1st reference voltage Vref1 to produce the 2nd reference voltage Vref2. This voltage Vref2 is supplied to a reverse input terminal of a comparator 8. An integrator 7 integrates the load power after an ignition phase every half cycle of an AC power supply, and this integration output is supplied to a non-reverse input terminal of the comparator 8. The comparator 8 compares the integration output fed from the integrator 7 with the voltage Vref2. When the former exceeds the latter, the comparison output is produced to reset an FF3. Therefore transistors Tr131 and 132 of a drive circuit 13 are turned on and off respectively. Thus a drive transformer 133 is de- energized. Then a main Tr41 of a switching circuit 4 is arc-extinguished since the supply of base current is stopped.

Title: Method for growing gaas single crystal
Inventor: HASHIO KATSUSHI
IPC: C30B27/02
Filed: 1995-03-14
Abstract: PURPOSE: To easily control the carbon concentration in single crystal and enable free control of the specific resistance of the single crystal by adding gallium oxide to the feedstock, when a single crystal pf GaAs is grown by the liquid- sealed Czochralski process. CONSTITUTION: A crucible is placed on the center of the high-pressure chamber and the melt of the feedstock is contained in the crucible and sealed with a liquid sealant of B2 O3 . Then, the seed crystal is dipped in the feedstock melt and pulled up the GaAs single crystal for growing. When this liquid-sealed Czochralski process is carried out, gallium oxide is previously added to the feedstock. The added gallium oxide dissolves in the liquid sealant of B2 O3 to react with carbon after the feedstock melts to liberate carbon monoxide. Thus, the carbon concentration in the growing crystal can be controlled by varying the weight ratio of gallium oxide to the sealant B2 O3 . The gallium oxide may be charged in the bottom of the crucible, but the use of the B2 O3 sealant to which gallium oxide is previously added is easier controllable.
