Title: Channel selecting device
Inventor: ITO MAKOTO
IPC: H03J5/00
Filed: 1986-10-21
Abstract: PURPOSE:To shorten time required for channel selection by permitting an electronic turning means to measure time required for an incoming radio wave to be received and calculating a digital tuning voltage when the electronic tuning means receives the incoming radio wave. CONSTITUTION:A digital tuning voltage from a tuning voltage generation means 12 is D/A-converted and supplied to the electronic tuning means 10. A timer means 12 counts time until the electronic tuning means 10 receives the incoming radio wave after a 1st digital tuning voltage has varied the digital tuning voltage from the tuning voltage generation means 12 to a 2nd digital tuning voltage. From the measured time, a calculation means 14 calculates the digital tuning voltage when the electronic tuning means 10 receives the incoming radio wave. Thus the channel selection time, especially time of obtaining the channel selection digital tuning voltage, can be shortened.

Title: Electronic picture printer
Inventor: ROORENSU EMU DAGURASU
IPC: H04N1/113
Filed: 1988-10-04
Abstract: PURPOSE: To simply and reliably print an image on an image recording material by generating a raster scan image based on an objective modulated light beam on an image recording unit by a combination of movements provided by an optical scanning device and a cassette driving device. CONSTITUTION: A low speed scanning is synchronously performed with a high speed scanning. When a driving motor 66 is worked, a leadscrew 70 is simultaneously rotated and a film cassette carriage 46 is synchronously forwarded. A raster scan of an image is performed on an image forming region 22a by a synthetic effect of the low speed and the high speed scanning movements. Energizations of light emitting diodes 106a, 106b and 106c are synchronized with the low speed and the high speed scannings. This is because the energization is synchronized with rotation of a motor 66 as an encoder timing signal is proportional to the speed of an encoder vehicle 102. Therefore, the motor can be worked by an open loop mode even when a control device is not used for the work and light exposure is uniformly performed e.g., speed of the motor is fluctuated.

Title: Transfer recording medium
Inventor: MIYAGAWA MASASHI
IPC: B41M5/30
Filed: 1988-10-06
Abstract: PURPOSE:To enable formation of a three-color image constituted of red, blue and black colors, with high sensitivity, little fogging, favorable wavelength selectivity and low possibility of void formation in image area or the like by making appropriate the combination of the photosensitive wavelength regions of elements and the hues of pigments. CONSTITUTION:An element A comprises a photopolymerization initiator having an absorption maximum in the wavelength range of 300-360nm and a red pigment. An element B comprises a photopolymerization initiator having a absorption maximum in the wavelength range of 360-430nm and a blue pigment. The blue pigment has a low transmittance for light of a wavelength of 300-360nm and a high transmittance for light of a wavelength of 360-430nm. Therefore, the blue pigment reduces greatly the sensitivity to fluorescent lamp light with a peak wavelength of 335nm, but reduces only slightly the sensitivity to fluorescent lamp light with a peak wavelength of 390nm. Thus, the element B with the photosensitivity peak wavelength in the range of 300-360nm is enhanced in wavelength selectivity. Similarly, the addition of the red pigment to the element A with the photosensitivity peak wavelength in the range of 300-360nm enhances the wavelength selectivity of the element A, because the red pigment has a high transmittance for light of a wavelength of 300-400nm and a low transmittance for light of a wavelength of 400nm or above.
