Abstract: PURPOSE:To carry out sharp 2-color recording on a photosensitive drum without mixing of 2-color toners, by conducting formation of the first latent image and its development, then formation of the second latent image and its development. CONSTITUTION:Potential VS is given to photosensitive drum 5 with charger 7, drum 5 is exposed positively with exposing means 12, and a latent image is formed, with potential VL of its exposed areas controlled to about 1/2 of VS. The latent image is developed positively with black toner 20 having negative charge in first developing device 13. Then, drum 5 is positively exposed with second exposing means 15 so as to render the potential of the exposed areas nearly zero V, and developed positively with red toner 21 having negative charge in second developing device 16. At that time, developing bias voltage is kept at about zero V, thus permitting an image of black and red toners to be formed on drum 5, and sharp 2-color recording to be made on drum 5 without mixing of 2-color toners in such a structure.

Title: Bending torsional quartz oscillator
Inventor: KAWASHIMA HIROFUMI
IPC: H03H9/19
Filed: 1979-12-19
Abstract: PURPOSE:To obtain the bending torsional quartz oscillator with stable oscillation, by selecting the crystal impedance of the main- and suboscillation to an optimum value, through the change in the size of oscillator. CONSTITUTION:Taking the phase difference of the amplifier A and feedback B as respectively LA and LB, the amplification factor and feedback ratio as respectively alpha and beta, and the amplification factor alpha and the phase difference LA as constant, the oscillating conditions can be determined with the feedback ratio beta and LB. The beta and LB are changed with the crystal impedance CI of the quartz oscillator. Further, to keep stable oscillation at the main oscillation at the temperature change of -10C-+60 deg.C, RS/RM must be taken greater than 5, where the CI of the main oscillation and suboscillation are respectively RM and RS, and if this ratio is too greater, then the frequency difference between the bending mode and the torsional mode oscillation must be taken smaller, thus <=30 RS/RM is taken. Thus, by selecting RS/RM to an optimum value, the oscillator which offers stable oscillation can be formed.

Abstract: PURPOSE:To improve position recognizing ability by making an adjustment with the proper quantity of reflected light on the whole even if the quantity of reflected light from an object of detection varies. CONSTITUTION:An arithmetic processing part 11 segments areas regarding respective light sources on an image memory 10 and calculates a distribution of brightness with specific cutting light L in each area S. For example, picture elements having higher brightness than a specific value in each area S are counted and the counted value is compared with shape information on the object 2 of inspection stored previously on the image memory 10 to decide whether or not the value is within a range with certain width. Then the output of a light source 3 is increased or decreased according to the value. Said operation is repeated to obtain the cutting light L which is uniform in the quantity of reflected light. Consequently, a binary image is obtained.
