Inventor: YURUGEN KURUPE
IPC: C07C51/02
Filed: 1995-01-11
Abstract: PURPOSE: To obtain an acidic org. compd. of high purity in a high yield by releasing the acidic org. compd. from an aq. soln. of a salt thereof by carbon dioxide in the presence of a water-insoluble org. solvent and subjecting an org. phase to re-extraction with carbon dioxide-containing water.

Title: Digital phase synchronizing circuit
Inventor: ITO TAKEO
IPC: H03L7/06
Filed: 1990-01-10
Abstract: PURPOSE:To suppress the ripple of an output signal in synchronization by stopping up/down counting operation in the case of detecting that the phases of 1st and a 2nd signals are coincident with each other. CONSTITUTION:A phase comparator 1 compares the 1st and 2nd signals with each other and an up/down counting part 7 controls the counting-up or counting- down operation with a phase difference signal to send out a carrying or borrowing signal. A pulse adding/removing means 5 generates the frequency 2-demultiplier clock of an input clock when the carrying and borrowing signals are both not inputted, the clock obtained by adding one clock to the frequency 2-demultiplier signal when the carry signal is inputted, and the clock obtained by removing one clock when the borrowing signal is inputted, and then performs frequency N-demultiplication to send a 2nd signal. When a phase comparison part 6 detects the synchronous state between the 1st and 2nd signals, the counting operation is stopped. Consequently, the ripple generated in the output signal of the up/down counting part 7 is suppressed.

Title: Digital broadcast receiver
Inventor: FUNAYA KOICHI
IPC: H04N19/70
Filed: 1999-01-08
Abstract: PROBLEM TO BE SOLVED: To obtain a digital broadcast receiver for simultaneously filtering plural carrier streams outputted from plural demodulation parts in parallel and simultaneously providing plural program information to a user. SOLUTION: A program filter 1 is provided with plural packet filters 11 each of which receives an input from each demodulation part 2 and extracts only necessary information based on user's specification from the input and plural memory interfaces 12 each of which writes an output from the corresponding packet filter 11 in a memory buffer 3. Each packet filter 11 judges whether packet ID included in each packet of a carrier stream to be an output from the demodulation part 2 coincides with previously registered packet ID or not, and at the time of judging the coincidence, passes the packet. Each memory interface 12 writes the packet passed through the filter 11 in the buffer 3 so that the filtered result can be accessed from the user.

Title: Synchronous counter
Inventor: MIYAZAWA KANICHI
IPC: H03K23/50
Filed: 1981-01-12
Abstract: PURPOSE:To decrease the number of elements and to reduce power consumption greatly by simplifying a circuit by using as a state inversion control signal each of output signals of MOS transistors (TR) which are provided in series and each receive the output of a prescribed stage of an FF as a gate input. CONSTITUTION:An FF1 is set and reset repeatedly at the rising timing of a clock pulse CP. Its set output Q1 and reset output Q1' turn on MOSTRs 1 and 4 respectively. Therefore, an inversion control signal C2 appearing at the output terminal n1 of the TR1 has a signal waveform similar to that of the output Q1 of the FF11. While this signal C2 is generated, an FF12 is set and reset at the rising timing of the pulse CP, so an inversion control signal C3 appearing at the output terminal of a TR2 has pulses a half as many as the signal C2 has. Thus, a state inversion control signal Ci for FFs 11-14 goes up to 1 when FF outputs of preceding stages are all at 1, and the FFs 11-14 repeat hexadecimal up- counter operation. Consequently, the number of elements of a state inversion  control circuit for the FFs is decreased.

IPC: H02M3/28
Filed: 1986-01-13
Abstract: PURPOSE:To prevent a winding of a transformer from burning out by stopping the oscillation of an inverter when the output current of the inverter becomes more than the predetermined value. CONSTITUTION:From a DC power source 1 a load 3 such as the halogen bulb is fed through a two (2)-transistor type sinusoidal wave inverter 2. This inverter 2 is composed of an oscillating transformer 4, transistors 5a-5b, a resistance, a condenser C0, a DC bias source 6, and a feedback winding 7. On this occasion, an output current detecting element 10 and a control element 20 are provided. When a load 3 above the rating is connected, etc. to the inverter 2, the output current detecting element 10 detects this overcurrent, and when the current comes up to above the predetermined fixed value, signals are sent out to the control element 20.

Title: Electrophotographic photoreceptor and electrophotographic image forming device
Inventor: SATO YOSHIHIRO
IPC: G03G21/00
Filed: 1998-01-09
Abstract: PROBLEM TO BE SOLVED: To obtain a surface protective layer in an optically uniform state which does not cause scattering of light or bleeding, which has low surface energy and excellent mechanical characteristics such as hardness and strength without degradation in surface resistance due to arc discharge, and which maintains high quality in a high humidity environment by incorporating colloidal silica and siloxane resin, and further conductive particles into the surface protective layer. SOLUTION: The surface protective layer of the electrophotographic photoreceptor contains colloidal silica and siloxane resin, and moreover, conductive particles. The layer is formed by applying, drying and hardening a compsn. for the protective layer of the electrophotographic photoreceptor on the surface of the electrophotographic photoreceptor. As for the conductive particles, metals or metal oxides are used. The volume resistivity of the protective layer is 1×10<9> to 1×10<15> Ωcm. If the resistivity is less than 1×10 Ωcm, the quality easily 1 degrades because the charges in a formed latent image are diffused. If the resistivity exceeds 1×10<15> cm, the charges can not move enough after exposure till development, which easily causes decrease in the apparent sensitivity and higher residual potential.
