Title: Synchronizing separator circuit
Inventor: KODAMA KAZUNORI
IPC: G09G3/36
Filed: 1994-09-29
Abstract: PURPOSE: To keep a stable synchronizing separation level at all times by providing a voltage control means and a constant current means controlling a current of a signal outputted therefrom to be constant and using a voltage of an output signal of the constant current means for a threshold level. CONSTITUTION: A signal V1 received from an input terminal is given at first to an input buffer 51 and given to the synchronizing separator circuit 50, in which the inputted synchronizing signal is synchronously separated. Furthermore, the synchronizing signal separated by the circuit 50 is amplified by an amplifier circuit 52 and fed to a voltage control circuit 53, in which the signal is converted into a DC voltage and it is fed to a constant current circuit 54. The circuit 54 is made up of an operational amplifier OP1 , a transistor (TR)7 and a resistor R20 . An emitter voltage of the TR1 is limited so as not to exceed an emitter voltage of the TR7 thereby inhibiting it that the emitter voltage of the TR7 reaches 0V and the operation of the circuit 54 is stopped. Thus, the change in the synchronizing separation level is decreased to keep the synchronizing separation level constant.

Title: Fault locator for cable
Inventor: MIYAMOTO TOSHIHARU
IPC: G01R31/08
Filed: 1992-09-03
Abstract: PURPOSE:To locate fault highly accurately by previously determining an apparent propagation delay time of surge caused by passage through a singular point such as a cross bond thereby correcting the surge detection time of magnetic field sensor. CONSTITUTION:Surge occurring upon fault of a cable is detected through at least two magnetic field sensors arranged at an appropriate interval along the cable and then the fault is located based on the difference between detection times. In this case, apparent propagation time of surge is delayed due to attenuation of the surge at a singular point, e.g. a cross bond, on the cable route. The propagation delay time of surge is previously measured by injecting a surge simulation waveform into a simulation circuit in order to correct surge detection time of the magnetic field sensor. An impulse voltage is applied on the simulation line system in order to simulate a point Q, separated by a predetermined distance from a cross bond IJ1, as a fault point. No fault is present in the section between the magnetic field sensors S1, S2 and this section is recognized as a sound section, thereby.

Title: Catalyst for purifying exhaust gas
Inventor: KUROKAWA TAKAHIRO
IPC: B01D53/94
Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To oxidize and decompose soluble organic fraction in exhaust gas by depositing ceria on a support material having meso pores. SOLUTION: Ceria or other catalytic constituents having O2 storage effect such as zirconia are deposited on a support material having meso pores by a spray-drying method, an evaporation-dry solidification method or the like. Any type of a support material can be used as long as the material has meso pores and a meso-porous silicate is suitable. Since the particle diameter of ceria is larger than that of Pt in the state that ceria is deposited on the support material, the ceria particle on the support material is scarcely covered with SOF(soluble organic fraction) completely. Consequently, contact of the ceria particle with oxygen in an exhaust gas is reliably maintained and oxygen is efficiently used for oxidation decomposition of SOF. Moreover, since the ceria itself has O2 storage effect, oxygen parting from the ceria can be used for oxidation decomposition of SOF.

IPC: H03M1/08
Filed: 1989-09-14
Abstract: PURPOSE:To reduce noise quantity leaked to an analog circuit by always decreasing the number of lines of changing in digital output lines when a change in an analog input is less. CONSTITUTION:To an analog input, 15 sets of comparators 1-15 are connected in parallel, the analog input is compared with 15 steps of voltage E1-E15 by the comparators 1-15 and the result is quantized to obtain 15 binary-coded comparator parallel outputs. The binary-coded outputs are encoded through an encoder to obtain digital outputs in response to the analog input. When a change in the analog input is minimum, the number of lines whose digital output varies is always 1. Thus, the production of a fixed pattern noise due to a digital signal leaked to the analog circuit is reduced.
