Abstract: PURPOSE:To improve a speech quality, by generating a signal having amplitude and phase which erase a beat sound from a sound signal obtained by demodulating FM and PM signals, from an AM component of the FM and PM signals, applying it to a demodulating sound signal, and erasing the beat sound. CONSTITUTION:When a beat is generated in an output of a discriminating circuit 4 by interference from other office, an AM component is fetched by a detecting circuit 6 simultaneously, and a beat sound is detected. The beat sound fetched as the AM component by the detecting circuit 6 is adjusted by an adjusting circuit 7 so that its phase is opposite to the beat generated in the output of the discriminating circuit 4 and the amplitude becomes equal to the latter, and the beat sound is erased by a subtracting circuit 9. In this case, FM and PM components are not detected by the detecting circuit 6, therefore, no call signal is erased.

Abstract: PURPOSE:To enable stable production of a steel strip having excellent ductility and aging resistance in the stage of overaging treatment during the production process of a cold rolled steel strip by controlling adequately the time when the supersatd. solid soln. carbon in the steel strip decreases by half. CONSTITUTION:A steel slab contg. 0.01-0.10wt% C and 0.01-0.10wt% sol. Al is hot rolled and is coiled at 720 deg.C. Such hot rolled steel strip is cold rolled to a steel strip having a prescribed thickness and is then heated continuously to a prescribed temp. The heated steel is annealed by a soaking treatment for specified time. The cold rolled steel strip subjected to the annealing treatment is subjected continuously to overaging treatment at and for a prescribed temp. and time after quick cooling. The time (h) when the quantity of the supersatd. solid soln. carbon decreases by half in such overaging treatment is so controlled as to be kept within the range expressed by the formula (1) to accerate the growth of the deposition nuclei of the carbide and to precipitate the supersatd. solid soln. carbon.

IPC: C08L27/00
Filed: 1982-03-26
Abstract: PURPOSE:A colored resin composition having transparency and ultraviolet screening property, freed from harmful matter and suited as a material for food containers, prepared by mixing a transparent resin with a finely divided colored titanium oxide powder having a specified specific surface area. CONSTITUTION:A transparent resin is mixed uniformly with 0.05-5wt% finely divided colored titanium oxide powder with specific surface area of 15-50m<2>/g. Any transparent resin can be used as fas as it is transparent, but resins used especially for food package include polyethylene, polypropylene, polyester, acrylic resin and polyvinyl chloride. When the finely divided colored titanium oxide has a specific surface area <15m<2>/g, the transparency of a resin composition is lowered and the visual inspection of the inside of a container prepared therefrom becomes difficult. Although there is no upper limit of the specific surface area, the limit which can be attained by the present production process is 50m<2>/g.

Title: Electromagnetic drive system
Inventor: KASHIWAZAKI TOMOYUKI
IPC: H02P25/06
Filed: 1983-03-22
Abstract: PURPOSE:To reduce the secondary effect to other circuit which is electromagnetically coupled to a drive coil by connecting a thyristor between the coil and a drive transistor. CONSTITUTION:When input signals I1, I2 are respectively supplied to input terminals A-A', B-B', photocouplers P1, P2 become ON, and a drive transistor T2 and a thyristor S1 become ON. Thus, a current Is is flowed to a drive coil L. When the current Is becomes a latching current or higher, the signal I1 is interrupted. When the signal I2 is interrupted in this state, the current Is is flowed through the coil L, the thyristor S1, and a diode D1. When the current Is becomes the holding current or lower, the thyristor S1 is interrupted. When thus constructed, even if an induced voltage is generated in the coil by the other circuit at non-drive time, a shortcircuit current is not flowed through the diode.
