Title: Manufacture of homoallyl alcohol derivative
Inventor: TORII SHIGERU
IPC: C25B3/25
Filed: 1984-02-29
Abstract: PURPOSE:To improve the overall efficiency of the manufacture of the titled deriv. by a known method by recycling a tin compound produced as a by-product when the titled deriv. is manufactured by reacting diallyl tin dihalide with ketone or aldehyde. CONSTITUTION:Ketone or aldehyde represented by general formula II is converted into homoallyl alcohol represented by a general formula IIIa and/or IIIb. A quadrivalent tin compound produced as a by-product during the conversion reaction is optionally taken out of the reaction system, and it is converted into a bivalent tin compound or metallic tin by electrolytic reduction. This product is reacted with allyl halide represented by general formula IV, and the resulting diallyl tin dihalide represented by general formula I is reacted with said carbonyl compound represented by the general formula II as a starting material. Thus, the tin compound as a reactive agent is recycled. By this method the overall efficiency of the manufacture of a homoallyl alcohol deriv. is improved.

Filed: 1988-02-19
Abstract: PURPOSE:To display a clear moving picture without generating any irregularity in illuminance on a screen by controlling the writing and erasure of the liquid crystal light valve with the wavelength of light which is projected on a photocondutive layer. CONSTITUTION:A laser beam light source 501 for image erasure is modulated by a modulator 502. A laser beam light source 503 for image writing is modulated by a modulator 505 according to the laser beam light source 501 for erasure.

Title: Synchronizing separating circuit
Inventor: KURIHARA IKUO
IPC: H04N5/08
Filed: 1985-02-28
Abstract: PURPOSE:To easily devise the titled circuit with MOS type elements by constituting the said circuit with a comparator circuit that has a constant inverse voltage and a bias generating circuit whose output voltage differs from the former's said voltage by a determined amount. CONSTITUTION:The synchronizing signal of a composite video signal 6 is inputted to an input terminal 4. When the said signal exceeds the inverse voltage 7 of the comparator 1 in the negative direction, the output 9 of the comparator becomes of low level. At the same time, the bias generating circuit 2 outputs a voltage VB which is VC-DELTAV, and the voltage differential between the input voltage and the bias power voltage is held in a coupling capacitor 3. Then, when the output cycle of the synchronizing signal ends and the backporch part is reached, the input composite video signal 6 increases its voltage by the amount equal to the voltage of the synchronizing signal part. And the output 9 of the comparator 1 becomes of high level. Because the video signal component of the video signal 6 is at all time higher than the backporch part, the output 9 of the comparator 1 becomes of low level only when the video signal 6 is at the synchronizing part, and consequently, a synchronizing separating output is obtained.

Title: Phase synchronizing system
Inventor: OTA TAKAO
IPC: H03K5/00
Filed: 1988-02-22
Abstract: PURPOSE:To shorten the setting time of a phase cycle by resetting a frequency dividing circuit by force when the initial phase difference of an external input signal and a purpose signal is large and changing a dividing ratio temporarily when the phase difference is small. CONSTITUTION:A reset signal generator 8 generates a reset signal of which an external input signal is synchronized with an (n) times clock signal. The reset signal compares the size of a phase difference obtained a 1/n frequency divider 2 by a phase difference judging signal 9. As a result, when an initial phase difference is large, the divider 2 is reset by force, and a purpose input signal 3 is coincided to the phase of an external input signal 5 generally. Then, when the phase difference is small, it is coincided to within the range of + or -1 clock cycle by changing the frequency dividing ratio of the circuit 2 temporarily to 1/n+ or -1. Thus, even when the initial phase difference is large, a time needed for the setting of a phase cycle can be shortened.
