Title: Growing method in gas phase of semiconductor of compound of 3-5 group element
Inventor: DOUSEN MASASHI
IPC: C30B29/40
Filed: 1980-04-15
Abstract: PURPOSE: The base body is placed downstream and a metal of III group in the periodic table, upperstream in regard to the reaction gas flow in the reaction tube and a chlorinated hydrocarbon is sent together with a carrier gas from the outside of the reaction tube near the above metal and another gas containing a V-group metal is fed between the base body and the III-group metal, thus growing a semiconductor of a compound of elements in both groups of III and V.  
     CONSTITUTION: For example, in the reaction tube of quartz 1 in which a reaction gas is made to flow, a base 3 such as GaAs base is placed downstream and a Ga source, i.e., at least one of III-group metal sources 2, is placed upperstream. A chlorinated hydrocarbon, which is liquid at room temperature, such as trichloroethylene is sent from the outside of the reactor together with a carrier gas near to the III-group metal source and another gas 6 containing at least one of V-group metal such as AsH 3  is fed between the base body 3 and the III-group metal source. Trichloroethane reacts with Ga to form GaCl, which reacts with the As formed by the pyrolysis of AsH 3  to deposit GaAs on the base body 3.

Title: Ultrasonic motor
Inventor: YAKIDA YASUNOBU
IPC: H02N2/00
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To improve workability in an assembling work, by sequentially applying to the signal terminals of the four output circuits of an ultrasonic motor predetermined-frequency signals having shifted phases of ninety degrees from each other, and by contacting pressingly a driven body with the end surface of its annular piezoelectric vibrator. SOLUTION: One surface of an annular piezoelectric vibrator VT is divided into four quadrant electrodes E1-E4 present radially from its center to connect them with the emitters of transistors Tr2 of output circuits 0T1-0T4 of an ultrasonic motor, and a whole-surface electrode AE of its other surface is connected with the earth. When inputting OFF signals successively to signal terminals Tm1-Tm4 of the output circuits E1-E4, field effect transistors FTr become OFF. Then, transistors Tr1, Tr2 are brought into ON states to apply successively to the electrodes E1-E4 of the annular piezoelectric vibrator VT a DC voltage from a DC power supply Vcc through the output circuits OT1-OT4. Since a progressive wave is generated to rotate it on the end surface of the annular piezoelectric vibrator VT, a driven body can be driven by contacting pressingly the driven body with this end surface.  As a result, the workability of an assembling work can be improved.

Title: Fixing device
Inventor: TAKAHASHI MASARU
IPC: G03G15/20
Filed: 1989-03-03
Abstract: PURPOSE:To reduce the extent of damage of respective equipments a fixation part when a temperature fuse is blown by providing an auxiliary reference voltage for heating to temperature a little bit lower than specific set temperature. CONSTITUTION:When the power source of a printer is turned on to raise the temperature of a fixing roller, a sequence control circuit turns on the SW 2 of an electronic switch 21 and then the auxiliary reference voltage is inputted to a comparator 19, so that the fixing roller is brought under temperature control to the auxiliary set temperature as target temperature. Therefore, the set temperature in the beginning of temperature raising operation is set to auxiliary set temperature lower than normal set temperature, so an overshoot does not increase. Consequently, even if the abnormal state wherein the temperature fuse is blown occurs, none of the various equipments around the fixation part damages greatly.
