Title: Method and apparatus for manufacturing patterned material
Inventor: OKADA KAZUHIKO
IPC: B29C48/03
Filed: 1981-02-04
Abstract: PURPOSE:To manufacture a molded material with a marbly pattern having a vignettig effect by a method in which a different color material is injected into a softened synthetic resin against the flow of the resin and mixed with the resin, and the resin is introduced into molds. CONSTITUTION:A softened synthetic resin is pushed into a mixing chamber 4 while being stirred by a pressure feeder 2, and at the same time different color materials are injected into the pressure feeder 2 side from holes 8 and 9 at the inside end 5 of the holding ring 4 of a mandrel 3. And, they are mixed together in the mixing chamber 14 and then sent into a mold body 10. Thus, a molding with a marbly pattern having a vignetting effect in which light color portions 12 and 13 are gradually changed in relation to thick color portions can be obtained.

Title: Production of high-purity antimony pentoxide powder
Inventor: YOSHIZUMI MOTOHIKO
IPC: C01G30/00
Filed: 1987-01-28
Abstract: PURPOSE:To obtain high-purity Sb2O5 in high yield in a short time, by reacting SbCl3 with NH4OH and oxidizing the reaction product with H2O2. CONSTITUTION:An SbCl3 solution dissolved in hydrochloric acid or in an alcohol is dripped into NH4OH preferably at room temperature - 100 deg.C. As an alternative, NH4OH is dripped to an SbCl3 solution. After the completion of the reaction, H2O2 is dripped to the reaction mixture to form colloidal precipitate of Sb2O5. The precipitate is separated by filtration and dried to obtain the objective Sb2O5 powder. Since a solution containing alkali metal, etc., is not used in the process of the present invention in contrast to conventional process, the contamination with the residual alkali metal element can be prevented. Furthermore, since NH3 and Cl2 can be removed in the calcination step, Sb2O5 powder having extremely high purity can be produced by this process.

Title: Transistor drive circuit
Inventor: YAMAKAWA SHIGEKI
IPC: H03K17/56
Filed: 1994-02-10
Abstract: PURPOSE:To decrease a turn-on delay time of a transistor (IGBT) to be driven and to slow down a rate of change in a collector current when the IGBT is turned on. CONSTITUTION:When a drive signal given to a drive signal terminal 8 reaches an H level, a turn-on gate drive transistor(TR) 4 is conductive and an IGBT 1 is conductive. In this case, when a gate voltage of the IGBT 1 is a threshold voltage or below, a gate voltage detection circuit 11 activates a bypass circuit 12 to bypass a turn-on time reduction resistor 3. Thus, a rising time of the gate voltage is reduced to reduce a turn-on delay time. When the gate voltage exceeds the threshold voltage, the bypass circuit 12 is not activated to reduce a rate of change in the gate voltage thereby suppressing a rate of change in the collector current of the IGBT 1.

Inventor: SUZUKI AKITOMO
IPC: F16H61/00
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To prevent reduction in the durability of frictionally engaging elements. SOLUTION: When an auxiliary shift mechanism is in a second-speed or a third-speed, a signal pressure from a first solenoid valve S1 is interrupted by a third shift valve 22 not to be supplied to a first shift valve 20. Thus, when the auxiliary shift mechanism is in the second-speed or the third-speed, the first shift valve 20 is not switched, and a main shift mechanism is not shifted down to first-speed. Thus, a large torque increased by the speed reduction of the main shift mechanism can be prevented from being inputted in the auxiliary shift mechanism, and the reduction in the durability of frictionally engaging elements of the auxiliary shift mechanism (frictionally engaging elements B4, C3 for achieving second speed or third speed) can be prevented.
