Abstract: PURPOSE:To prevent a pseudo-retraction and to obtain a normal demodulation data by providing an absolute value circuit obtaining the absolute value of an output of a first integrator and a level deciding device and controlling the first integrator by an output of the level deciding device. CONSTITUTION:An absolute value circuit 9 obtaining the absolute value of an output of a first integrator 1 is provided and a level deciding device 10 deciding the largeness of the output of the circuit is provided in addition. Thereby, the absolutervalue of a value of a register is viewed in the circuit 9, the largeness of the output of the circuit 9 is detected by the deciding device 10, and when the value goes to above a previously set predetermined value, the value of the register of the integrator 5 is cleared. As a result, a carrier offset value or the like such as generating the pseudo-retraction including a 90 deg. rotating carrier off set value or 180 deg. rotating carrier offset value is not stored. Namely the pseudo-retraction is prevented and a normal demodulated data can be obtained.

Filed: 1989-04-18
Abstract: PURPOSE:To obtain a printed circuit board having excellent insulating resistance and corrosion resistance by washing the printed circuit board which is soldered after treating with a rosin active flux by extracting the hygroscopic activator in the flux residues with water added with a water soluble solvent. CONSTITUTION:The rosin in the flux residues securely sticking to the printed circuit board subjected to the soldering is swollen by the water soluble solvent by which the solvent is intruded into the inside. The water which is the chief material is in succession infiltered into the rosin so that both integrally extract the hygroscopic activator contained in the flux residues and to derive the same into the water. The hygroscopic activator in the flux residues sticking to the printed circuit board is removed to leave only the non-hygroscopic rosin. Isopropanol among methanol or the like is representative as the water soluble solvent. The water is preferably pure water. A spray washing, dip washing or the combination thereof is adequate for the washing. The amt. of the activator of the rosin active flux is maximized in this way and the soldering defects are decreased to zero.

Title: Traveling car provided with copying sensor
Inventor: FUJIWARA KOUJI
IPC: A01B69/00
Filed: 1982-06-09
Abstract: PURPOSE:To detect a prescribed boundary with discrimination of the degree of the approach angle of a car so as to ensure the optimum steering control, by setting copying sensors with a prescribed space between them so that a virtual line connecting both sensors forms a folded line. CONSTITUTION:Copying sensors are set with a prescribed space between them so that a virtual line connecting both sensors forms a folded line, and therefore the degree of approach angle is discriminated for a car. That is, an optical sensor S1 is first turned on when the car approaches obliquely to a boundary of its traveling areas. Then an optical sensor S3 is turned on when the car approaches further with an angle less than 45 deg., and an optical sensor S2 is turned on with the approach angle larger than 45 deg.. Then the control is carried out with a quantitative steering degree regardless of the approach angle and with a small approach angle. If the approach angle is large, the approach angle theta is detected from the ON-time difference between sensors S1 and S2. Then a solenoid valve 14 is controlled via a buffer 15 to drive a hydraulic cylinder 6 so as to obtain a steering degree corresponding to the detected approach angle theta.
