摘要： PROBLEM TO BE SOLVED: To provide a structure for an optical printer head which can increase an exposure. SOLUTION: A light-emitting diode(LED) array chip 30 having a first and a second two arrays as light-emitting spot arrays is used for this optical printer head. The first light-emitting spot array exposes at a one time exposure. At a two time exposure, pixels exposed by light-emitting spots of the first array are first exposed and subsequently exposed by light-emitting spots of the second array. Since the head of two arrays of light-emitting spots is used, an exposure state of three stages of 0, 1 and 2 can be formed.

摘要： PROBLEM TO BE SOLVED: To provide a method of correcting the light quantity of an optical writing head by anticipating the temperature distribution of the optical writing head, and canceling the effects to printing quantity caused by the self temperature rise of the optical writing head. SOLUTION: When a first light emitting diode 201 is lit, its forward voltage can be measured by measuring the voltage V0 at a voltage output terminal 130. The forward voltage, which is hardly dependent upon current value, varies linearly against temperatures TH. The temperature TH of the first light emitting diode is anticipated by use of the temperature characteristics. By measuring the voltage V0 of two chips located apart on one head, environment temperature is estimated, and the temperature distribution of the head is anticipated from the difference in temperature of the two light emitting element arrays. Thus, light quantity of the light emitting elements is corrected in accordance with the anticipated temperature distribution.

摘要： PURPOSE:To form a dense SiO2 film on the surface of a base material by adding sulfuric acid to an aq. hydrosilicofluonic acid soln. in which SiO2 is in a supersatd. state, then bringing this soln. into contact with the base material. CONSTITUTION:Water is filled between an inside chamber 1 housing the aq. hydosilicofluonic acid soln. in which the SiO2 is held dissolved and satd. and an outside chamber 2. The soln. is heated by a heater 4 and is stirred by a stirrer 5 so as to be kept at a specified temp. The aq. soln. in the rear part 8 of the inside chamber is circulated to the front part 6 of the inside chamber via a filter 11a by controlling 3-way cocks 13a, 13a', 13b, 13b' and operating a circulating pump 12a. An Al sheet 15 is immersed into the rear part 8 and is held for 15 to 20 hours to obtain the treating liquid of 1 to 4mol/l Si concn. The sulfuric acid is added to this treating liquid so as to attain 10 to 10 S/Si molar ratio to the concn. of the Si component. The treating liquid is then circulated through the rear part 8 of the inside chamber, the filter 11b and the circulating pump 12a to the front part 6 of the inside chamber and the base material 14 is immersed into the middle part 7 of the inside chamber, by which the SiO2 film is formed on the surface of the base material.

摘要： PURPOSE:To improve the life time of semiconductor when the semiconductor is used in pigment, dimming glass, etc., by dispersing the semiconductor fine particles in treating liq. supersaturated with metal oxide, contg. metal ion and fluoride ion, by forming metal oxide coated film on the surface of the particles and by decreasing the photocatalytic activity. CONSTITUTION:The treating liq. supersaturated with metal oxide (e.g., ZnO), contg. metal ion and fluoride ion is prepd. by dissolving metal (e.g., Si, Zr) in hydrofluoric acid to almost saturation, and furthermore, by adding the metal oxide, metal hydroxide, etc. Then, the semiconductor fine particles coated with the insulator are obtd. by dispersing the semiconductor fine particles (e.g., titania fine particles) in the treating liq. to precipitate and form the metal oxide coated film on the surface of the semiconductor fine particles. Thereby, when the obtd. semiconductor fine particles are used as the pigment for cosmetics, skin chapping is scarcely caused, because of decreasing the photocatalytic activity.
