摘要： PURPOSE: To enable manufacturing a nonlinear element excellent in in-surface reproducibility, by forming a nonlinear resistance layer by a sputtering method using a target of zinc sulfide in which transition metal sulfide formed by sulfating transition metal element is mixed. CONSTITUTION: After an orientation film 61 is spread on the surfaces of an element side substrate 57 and a facing side substrate 59 on which surfaces nonlinear elements, electrodes, etc., are formed, orientation treatment is performed, and then the substrates 57 and 59 are so stuck to each other that the orientation film 61 becomes inside. Then a White-Taylor type guest-host liquid crystal 62 is injected in the part between the substrates 57 and 59, and the injection port is sealed. Thereby the formation of a liquid crystal display device is finished. In this manufacturing method, in-surface reproducibility is improved by using a ZnS target in which nickel sulfide is mixed. Thereby irregularity of elements between manufacturing lots is eliminated, so that a display device using the nonlinear element like this can be stably supplied.

摘要： PURPOSE: To improve the I-V characteristic or the ON-state current of a nonlinear resistance element by using material containing transition metal of nickel, iron, or the like in a zinc sulfide (ZnS) film as a nonlinear resistance layer. CONSTITUTION: A ZnS film 54 as a nonlinear resistance layer is provided on a scanning electrode 52 and an insulating film 53 formed on a glass substrate 51. A nonlinear resistance element 56 is formed out of the scanning electrode 52, the ZnS film 54, an electrode 55, and the like. By putting transition metal as impurities into the ZnS film, the I-V characteristic of the nonlinear resistance element can be changed. Namely by putting nickel as transition metal of 10μg-20mg into 1g of ZnS, ON-state current can be raised according to the quantity of nickel. Further, by putting iron as transition metal of 10μg-20mg into 1g of ZnS, steepness of the I-V characteristic can be increased.

摘要： PURPOSE:To make display with uniform colors by facilitating the control of the film thicknesses of color filters. CONSTITUTION:The color filters 5 are formed on one surface of a glass substrate 6 of a pair of the glass substrates 6, 8 and an ITO film is applied on the surface on the opposite side to form transparent electrodes 7. Further, an oriented film 11 is formed thereon. Plural pixel electrodes 9 are formed on one surface of the glass substrate 8. Two sheets of the glass substrates 6, 8 are stuck in such a manner that the transparent electrode forming surface and the pixel electrode forming surface face each other. A liquid crystal 10 is sealed therebetween and the substrates are sealed, by which a liquid crystal panel 3 is formed. Further, a UV curing adhesive 4 is applied on the front surface on the color filter 5 side of the liquid crystal panel. A microlens substrate 2 and the color filters 5 of the liquid crystal panel 3 are then superposed on each other with good accuracy. The UV curing adhesive 5 is irradiated with UV rays from the microlens substrate 2 side and is thereby cured to completely adhere the microlens substrate 2 and the liquid crystal panel 3, by which the projection type color liquid crystal display device 1 is produced.

摘要： PURPOSE:To prevent fluidity deterioration of toner with time by providing an external additive adding device which adds an external additive by a specific quantity against a replenished quantity of toner. CONSTITUTION:The toner in a toner hopper 4 is replenished to a developing tank 3 by the rotation of a toner replenishing roller 41 and the external additive in an external additive hopper 5 is replenished to the tank 3 by the rotation of an external additive replenishing roller 51. Since the rotating speed of the roller 41 is different from that of the roller 51, the toner replenishing quantity is different from the external additive replenishing quantity even when the rollers 41 and 51 rotate simultaneously. The ratio between the rotating speed of the roller 41 to that of the roller 51 is set so that the external additive replenishing quantity of the roller 51 can become 0.01-1.0 wt.% of the toner replenishing quantity of the roller 41. Therefore, the concentration, electrified quantity, etc., of the toner can be stabilized and a change in picture quality due to an increase in the picture forming number can be prevented.

摘要： PURPOSE:To obtain a stable concentration for developing by automatically replenishing a fresh developer and a carrier whenever the images of the fixed number of sheets are formed, and discharging the replenished developer or the deteriorated developer of the same quantity as that of the carrier. CONSTITUTION:After stirring rollers 3a and 3b are rotated, toner from a toner replenishing roller 4 and the developer in a developing tank 1 are stirred and mixed, they are magnetically attracted to a developing roller 2, the napping of the toner is adjusted, and then, they are carried to a photosensitive body D to carry out electrostic development. Thereafter, a counting signal is outputted to a controller 10 whenever a counting counter C counts the number of sheets for forming the image. Therefore, a developer replenishment control means 11 inside the device 10 drives the developer replenishing roller 5b of a developer replenishing device 5 and the developer is replenished into the developing tank 1 by a fixed quantity. Simultaneously, a carrying means 12 drives the stirring rollers 3a and 3b and carries the deteriorated developer to a discharging port 7. Further, a deteriorated developer discharging control means 13 drives an opening/closing device 9 to obtain a closed state of the discharging port 7, and the deteriorated developer is discharged on a deteriorated recovering container 6 via a L-shaped barrel.

摘要： PURPOSE:To obtain good images which are free from image fogging by setting the weight ratio of magnetic material powder with the toner granular material of the toner for supply in the initial period larger than the weight ratio of the magnetic material powder to the toner granular material of the toner for replenishment. CONSTITUTION:The weight ratio of the magnetic material powder to the toner granular material of the toner for supply in the initial period is set larger than the weight ratio of the magnetic material powder to the toner granular material of the toner for replenishment. The increase in the image fogging, the supply of the more than needed magnetic material powder and the decrease of a transfer rate in the initial period of copying of an electrostatic transfer type copying machine are, therefore, not resulted. The cost increase is thus obviated and the good images having the decreased image foggings are obtd. in the initial period of copying and the subsequent copying. The relation between the weight ratio (a) of the magnetic material powder to the toner granular material of the toner for supply in the initial period and the weight ratio (b) of the magnetic material powder to the toner granular material of the toner for replenishment is preferably 1.1b
