Title: Control circuit of recording device
Inventor: NAKAZAWA TAKESHI
IPC: B41J3/00
Filed: 1988-03-01
Abstract: PURPOSE:To make it possible to set the timing of a generation processing signal freely from outside by providing a parameter setting circuit consisting of a register and a comparator as an attachment to a timing circuit. CONSTITUTION:Registers 2-5 receive timing parameters from an external circuit as a clock count through signal lines 14-17, accumulate the values of the clock count, and output the accumulated data to comparators 6-9. Comparators 6-9 compare data entered from the registers 2-5 with an address value which is the count-up data of a basic clock generated in a counter 1. If both data agree to each other, a trigger signal is input to a timing generation circuit consisting of a vertical synchronous signal generation circuit 10, a horizontal synchronous signal generation circuit 11, a vertical enable signal generation circuit 12 and a horizontal enabled signal generation circuit 13. In each timing generation circuit, a timing signal of required shape for the control of an external circuit or a recording device is generated based on a trigger signal entered.

Abstract: PURPOSE:To form a color image having good quality which has high image density and no color shift without any deterioration in color tone by constituting a photosensitive body which has a color separating function so that spread area of developing toner is larger than its color separating function part. CONSTITUTION:Insulating layers 3 which form respective color filters are formed on a photoconductive layer 2 and when the photosensitive body which has the color separating function is exposed to an original image, a boundary sur face charge density image is formed at the boundary between layers 2 and 3, the entire surface is exposed to light transmitted through a specific color filters to form a latent image on the filter, and the image is developed with corresponding color toner. This operation is repeated to form a color image. In this case, the filters are increased in contrast and reduced in size and a developing bias voltage, etc., are specified to select development conditions; and then the spread area of developing toner becomes large and is 1.1-1.6 times the filter area. Consequently, the color image is of good quality having high image density and no color shift.

Title: Plastic optical fiber
Inventor: TSUJITA TERUYUKI
IPC: G02B6/00
Filed: 1984-03-16
Abstract: PURPOSE:To prevent the characteristics of transmission even under the conditions of high temperature/high humidity by forming a coat layer consisting of ultraviolet-hardened resin having a prescribed hardness value or more on the surface of an unextended plastic optical fiber strand. CONSTITUTION:The strand 1 of the plastic optical fiber (POF) consists of a core 1a and a clad 1b and is extended at the production of the strand. The coat layer 2 is formed on the surface of the strand 1 by ultraviolet-hardened resin having >=65 Shore hardness (JIS-K-7215) so that the film thickness is 5-200mu. When the POF is set up under the conditions of high temperature and high humidity, the POF strand 1 tries to contract, but since the hard resin layer having high intensity is applied to the periphery of the strand 1, the coat layer 2 is functioned like a tension member. Consequently, the contraction of the strand 1 is surely suppressed and the increase of transmission loss is prevented. Since the strand 1 is prevented from contraction, the interface between the core 1a and the clad 1b is prevented from vibration and the increase of transmission loss due to the vibration can be also prevented.

IPC: G02B6/124
Filed: 1982-03-29
Abstract: PURPOSE:To realize a tight construction monolithic with another optical element, by embedding a spherical core whose refractive index decreases from the center to the circumference according to the square of distance in a circumferential medium whose refractive index is selected depending upon at least center refractive index and the secondary and quadratic values of coefficients of distribution. CONSTITUTION:The sperical core 1 whose refractive index decreases according to the square of distance from the center to the circumference is embedded in the circumferential medium 2 whose refractive index is selected depending upon at least its center refractive index n(o) and secondary and quadratic coefficients G2 and G4 of distribution. The relation between n(o), G2 and G4, and refraction distribution n(r) is expressed by an equation where r0 is the radius of the spherical core 1. Consequently, the distribution of refraction is controlled easily to obtain a lens having less spherical aberration and tight unification with other optical elements such as an optical fiber is enabled. The spherical core has small refractive index in the spherical boundary surface and loss is reduced. Thus, a lens for microoptics which is strong and has high performance, many functions, and high reliability is obtained.
