Title: Electronic tuner
Inventor: UCHIYAMA MAKOTO
IPC: H04N5/44
Filed: 1990-03-08
Abstract: PURPOSE:To attain miniaturization of this tuner by operating a mixer circuit over a wide range. CONSTITUTION:Since a high fT transistor(TR) is employed for a mixer circuit 21 and the common emitter system is used, a high gain is attained. Since a low pass filter circuit 24 acts like an impedance matching circuit for the circuit 21 and an intermediate frequency amplifying circuit 25, the gain is further increased. The change in the output capacitor of the circuit 21 is reduced by setting the capacitor of the circuit 24 to a high capacitance. The cut-off frequency of the circuit 24 is set to the upper side of the intermediate frequency by 5-50MHz higher, then the frequency characteristic is improved. Thus, the mixer circuit is operated at a wide band to reduce two mixer circuits into one while keeping the performance equivalent to a conventional system or above. Thus, miniaturization of the tuner is attained and the cost is reduced.

Title: Ink jet printer
Inventor: SUTEIIBU OO RASUMUSEN
IPC: B41J13/00
Filed: 1988-03-11
Abstract: PURPOSE:To simplify a structure and to sufficiently dry paper before the next printing operation, by generating reverse warpage in a printing medium immediately before the printing medium enters a printing region and keeping the flatness of the aforementioned printing medium. CONSTITUTION:Paper 16c is transferred to a platen 26 from a guide 27 to draw reverse warpage (reverse bow shape) at a point A. By the reverse warpage at the point A, the paper 16c comes to lie flatly along the platen 26 in a region (printing region A) where a printing head passes. As a result, a strictly adjusted constant gap necessary for ink jet technique is kept between the printing head and the paper 16c. The reverse warpage is the directional change of the paper when the paper separates from a feed roller 24 to slide along the platen 26 and this directional change is generated by positioning the platen 26 at an angle different from the tangential direction of the paper feed roller 24 at the point A.
