Patent JP-H10322134-A (JP)
Title: Fm receiver
Inventor: WADA KIYOSHI
IPC: H03D3/06
Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To maintain a stable FM receiving state, even at a narrow intermediate frequency band by using a detection means which detects an error of the tuning frequency of a tuning circuit and a control means which controls a capacity variable means for restoring the error of the tuning frequency detected by the detection means. SOLUTION: If the tuning point of a phase shift coil T1 has a shift due to a temperature drift, a shifted DC component is generated at the S-curve output with respect to Vref, when the tuning point shifts to a higher level with respect to an intermediate frequency. The DC component is amplified by an amplifier IC2 and applied to an AD conversion port AD1 of a microcomputer IC3. Then the voltage of the AD1 is compared with the Vref voltage of an AD conversion port AD2 within the IC3. At the same time, the IC3 checks the TUNED output. When the TUNED output is set at an L-level, it is decided to be at a receiving state and the PWM output is changed, based on the difference between the voltage of the AD1 and AD2. In other words, DUTY is made small in order to reduce the DC voltage generated at a resistor R3.

Abstract: PURPOSE:To form a colored picture which is free from uneven color and uneven picture, by making rays of light from a bar type light source incident upon the surface of an original through a cylindrical lens and making the reflected light from the surface incident upon the surface of a photosensitive body through a bar-like lens array. CONSTITUTION:The rays of light from the bar-like lamps 3 of three colors are converged to an original O with a cylindrical lens 31 and the reflected light from the original O are made incident to the surface of a photosensitive body 1 through a bar-like lens array 33. Thus a primary latent image is formed. An electrostatic image is formed in blue filter sections on the surface of the photosensitive body by making blue rays of light incident to the surface of the primary latent image from a uniform light source 5B and a yellow toner image is formed by a developing device 7Y. Similarly, a magenta image and cyan images are respectively formed by means of light sources 5G and 5R and developing devices 6M and 6C. Therefore, a clear colored picture which is free from color shifting and uneven picture caused by uneven light quantities can be formed with a small-sized device.
