Filed: 1982-02-26
Abstract: PURPOSE:To record and reproduce clock pulses and a data signal through simple constitution by limiting the clock pulses to a prescribed frequency band through a band-pass filter and sending them out as a recording clock signal, and generating a composite signal from the clock pulses and data signal and limiting it to a prescribed frequency band through a band-pass filter. CONSTITUTION:The clock pulses CK are limited to the prescribed frequency band through the band-pass filter BPF1 to obtain a component consisting principally of a basic wave, which is sent out as the recording clock signal SRC. The clock pulses CK and data signal D are ANDed by an AND gate G5 and then supplied to an input IN1 of an adder AD; and it is further supplied to the other input IN2 of the adder AD after the data signal D is inverted by an inverter IN5 to obtain a signal (d) containing an AC component. From the signal (d), the AC component is extracted by a capacitor C and the band-pass filter BPF2 limits its frequency band to obtain a signal (e) consisting of only a basic wave component as well as the recording clock signal SRC, thereby sending a recording data signal SED out.

Inventor: SATOU MASAMITSU
IPC: B60T8/72
Filed: 1978-03-15
Abstract: PURPOSE: To exactly prevent skid phenomenon of a vehicle by again starting acceleration of wheels from when brake torque reducing period introduces danger of locking wheel and continuing it until the danger of locking wheel is exactly eliminated.  
     CONSTITUTION: Wheel peripheral speed is detected to produce a wheel speed signal Uwi to introduce a wheel acceleration signal U'wi from the signal Uwi. A standard wheel speed signal UR is set in the form to be compared with the signal Uwi, and standard wheel deceleration signal -V'wo and standard wheel acceleration signal V' wl are set in the form to be compared with the signal U'wi to thus compare the signal Uwi with the signal UR in brake manner and to compare the signal U'wi with the signal -V'wo and the signal V'wl. When the Uwi is smaller than UR and yet the V'wi is smaller than -V'wo, the brake torque starts to decrease, and when the V'wi becomes larger than V'wl, the brake torque reducing period is completed to thereby exactly prevent the skid.

The acid used can dissolve the Sc compd. as a sulfate, chloride or nitrate according to the kind of the acid in a short time. About one hour is enough as the dissolution time. The amt. of the acid used is controlled to obtain about 1.5 pH of the soln.  Thus, >=90% of Sc can be easily dissolved under the conditions described above without causing filtering failure of the soln. and the residue, and liquid-solid separation can be easily performed.

Title: Radar apparatus
Inventor: TOKORO SETSUO

Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To make preventable an erroneous detection by a radar by comparing a first estimation direction with a second estimation direction and adopting a direction coincident with each other as a detection direction. SOLUTION: A signal processing part 6 calculates the direction of a target so as to be used as a first estimation direction, on the basis of the phase difference in a received signal between element antennas which are arranged at an interval d1 out of a plurality of element antennas 1 to 3. The direction of the target is calculated so as to be used as a second estimation direction, on the basis of the phase difference in a received signal between element antennas which are arranged at an interval d2, which is different from the interval d1, out of a plurality of the element antennas 1 to 3.  In addition, when reflected waves arrive from a target in a direction in which a phase is turned up with reference to any element antenna, the calculation result of the first estimation direction is different from the calculation result of the second estimation direction, when the first estimation result and the second estimation result are calculated without taking into consideration that the phase is turned up. Consequently, a judgment means does not adopt both estimation directions as a detection direction. As a result, it is possible to prevent the erroneous detection of a direction.
