Title: Developing method of electrostatic latent image
Inventor: HOSHI NOBUYOSHI
IPC: G03G15/04
Filed: 1979-04-04
Abstract: PURPOSE: To form the image of reduced edge effect by applying corona discharging to the polarity at which charging saturates rapidly, to the photoconductive insulator of the specific material and performing development processing through the polarization of the magnetic toners.  
     CONSTITUTION: A photoconductive insulator 2 of selenium base having chargeability and light polarities is laminated on the substrate 1 of an electrostatic latent image substrate 3. If this insulator 2 is corona-charged to the polarity at which charging saturates rapidly, the charged charges are escaped by the corona discharge applied even after the saturation charging, by which discturbances are produced in the corona charge. As a result, the electric fields formed together with the latent image potentials according to the corona charging become uneven and the suction force of the toners 5... through polarization of the magnetic toners 5... supported by a toner substrate 4 changes, whereby the development processing of the reduced edge effect of the image peripheral parts is accomplihsed.

Title: Picture retrieving device
Inventor: SUGITA YASUTOSHI
IPC: G03B21/11
Filed: 1986-02-25
Abstract: PURPOSE:To stop a picture accurately at a prescribed position and to avoid the omission, etc. of a copied image by setting two sensors with a space secured by an amount equal to a distance double as much as the moving amount of a picture supporter obtained between the output of a specific stop signal and the stop of the picture supporter. CONSTITUTION:The space L between both sensors 21 and 22 is set in both film feeding directions (a) and (b) at a distance double as much as the film moving amount l1-l2=l4-l3 obtained between the output of a film feed stop signal and the actual stop of film. The distance between the right end of a mark (m) and the reference position Z is equal to l2 l4 when the film is stopped in each feeding direction as long as the film feeding speed is constant. Thus the film is stopped in a state where the mark (m) is always kept approximately at the same position regardless of the film feeding direction. Therefore, a desired picture frame A is stopped at a fixed position regardless of the film feeding direction. Then the space L can be changed in response to the film shift amount in case the film feeding speed is not fixed.

Title: Dc reproducing and synchronous separating circuit
Inventor: ABE NOBUMASA
IPC: H04N5/18
Filed: 1981-03-19
Abstract: PURPOSE:To realize both the DC reproduction and the synchronous separation of the luminance signal, by using a differential amplifier consisting of a transistor which is connected to an input terminal via a capacitor and a transistor which is connected to the reference bias. CONSTITUTION:The video signal supplied through an input terminal 1 is connected to a transistor TR8 of one side that forms a differential amplifier by an impedance converting TR and through a charging/discharging capacitor 3. The reference bias Vr, i.e., the prescribed voltage is applied to a TR9 of the other side of the differential amplifier via a bias TR13. The TR9 is turned on during the period of the synchronizing signal, and accordingly a TR4 is turned on. Thus the capacitor 3 is charged by an amount equivalent to a degree discharged in the period excepting the synchronous signal. As a result, the DC reproduction output with the synchronizing signal tip level kept constant emerges at the point B. On the other hand, the TR9 is turned on during the period of the synchronizing signal. Thus the synchronizing signal emerges at the point D. In such way, a DC reproducing and synchronous separating circuit that is suited to the IC conversion can be obtained.

Abstract: PROBLEM TO BE SOLVED: To efficiently examine an eye by storing a program with steps included for finding a corrective amount for adjusting a corrective degree, statistically processing many stored data for finding a variable factor to keep the corrective amount variable and then finding an anticipated treatment degree on the basis of the variable factor. SOLUTION: Judgement is made as to whether astigmatism exists and is related to a slantwise view, and far-sightedness as well as near-sightedness exists, on the basis of a complete binocular corrective value. Thereafter, degree adjustment is made and an adjustment degree is calculated. In the case of near-sightedness without any astigmatism, a correction amount ΔS1 is first found, based on an S-value weak degree eye for a complete binocular correction in the case of first mounting. Corrective treatment is thereby made at a step B-2. Then, right and left differences after the corrective treatment are compared with each other at a step B-3. When the difference exceeds 0.75D, the S-value for the strong degree eye is taken at a value with -0.75D added to the S-value for the weak degree eye at a step B-4.  At the time of calculating the correction amount ΔS1, a correction factor is taken into consideration and after collecting the data of many subjects, the mean value of correction factors are obtained and fed back.
