Abstract: PURPOSE: To raise gasification efficiency and heating efficiency by a method wherein a heating means in which a recording material of a recording material accomodating part is heated to be transferred to a material to be recorded is composed of a heating element which extends at least in a depth direction of the recording material accomodating part. CONSTITUTION: When a head 70 is operated as an actual vaporizer, a molten liquid dye 22 sucked up by a capillary phenomenon from a side surface of a piller-shaped body 175A of a micro-heater is heated at about 50-300 deg.C by the piller-shaped heater part 175A ranging over the whole in a depth direction. The dye 22 is vaporized from an upper part hole 150 of an electrode 85 and around an electrode 84 to be stuck to a material to be recorded, and printing can be carried out on photographic paper without any contact. In that case, the dye 22 permeated around the piller-shaped body 175A can be efficiently heated to be vaporized without fleeing. Further, since the heat is generated by the piller-shaped heating element 175A ranging in a depth direction of a dye accomodating part 87, the heat is held sufficiently over the whole of the dye, and there is hardly any influence caused by diffusion on a base 73.

Abstract: PURPOSE: To improve efficiency in gasification by transmitting heat efficiently to a recording material by a method wherein a porous structure which holds and feeds the recording material is provided at a position deeper than that of a heating element provided on a surface area of the recording material. CONSTITUTION: A heating element 75 is arranged on a surface area of a liquified dye 22 in a dye-accomodating part 87 of a printer head 70. Therefore, temperature of the liquified gas 22 is quickly raised on the surface area to make thermal efficiency by heating ascend, and efficiency in transfer of the dye by gasification can be improved. Further, a fine meandering pillar-shaped body 80 for holding and feeding the dye 22 is provided as a porous structure at a position deeper than that of the heating element 75 on the surface area of the dye 22 in contact therewith. Therefore, a capillary structure comes to be provided also to a gasification part 77, running away of the dye is inhibited by capillary action to hold the dye effectively and feed a specific amount thereof, and heat by the heating element 75 can be efficiently transmitted.

Abstract: PURPOSE:To make it possible to detect the intensity of a heating beam such as laser beam with a concurrent action to maintain the output utilization efficiency of the heating beam at high level, and enhance detection accuracy by introducing a beam intensity detection means through an area between a heating beam emission means and a recording material storage part during the non- heating time of a recording material. CONSTITUTION:If data is optically recorded, i.e., if a dye 22 is not heated by a laser beam, a light-receiving element 79 is inserted into an area between a laser 18 and a dye storage part 37 and the laser beam L having the same output intensity as an emitted laser beam L during recording is emitted directly into the light-receiving element 79 for front monitoring. A printer head 40 can use an output of the laser beam L required for the gasification of the dye on a recording sheet to a maximum extent without wasting the output. This is because the light-receiving element 79 is introduced into the proceeding direction of the emitted laser beam L only when the output is monitored, and the light- receiving element 79 is restored to an original position when recording data.

Abstract: PURPOSE:To facilitate the leading-out of a signal for detecting the distance from an irradiation part, e.g. the leading-out of a servo signal for focusing control of light irradiation to the irradiation part. CONSTITUTION:The equipment is provided with the following; an irradiation part 2, an optical element 21 having a light emitting part 1 and a first light receiving part 41, at least a second light receiving part 42 and a third light receiving part 43 which put the optical element 21 between them and are arranged on both sides of the element 21, and a covergent means 3. The first light receiving part 41 is arranged in the vicinity of the light emitting part 1, and receives the return light LR of the emitted light from the light emitting part 1 which return light travels from the irradiation part 2 toward the light emitting part 1. The second light receiving part 42 and the third light receiving part 43 are arranged step-wise in the manner in which one of the distances between the light receiving surfaces of the parts 42, 43 and the irradiation part 2 is large and the other is small as compared with the distance between the light receiving surface of the first light receiving part 41 and the irradiation part 2.

Abstract: PURPOSE:To form a high-output and low-noise semiconductor laser by a method wherein the reflectivity of the end face of the front of a resonator is specified and quantum well active layers are provided in an active layer. CONSTITUTION:The reflectivity of the end face of the front of a resonator is set at 20% or higher and 40% or lower, quantum well active layers 3a to 3c are sectioned by barrier layers 4a and 4b and light guide layers 2a and 2b are respectively provided on the outsides of the layers 3a and 3c. It is generally desirable that the thickness of the layers 3a to 3c is 1 to 20nm and a part consisting of the layers 3a to 3c, the layers 4a and 4b and the layers 2a and 2b is formed as an MQW layer. Thereby, a high output and low noise are reconciled and the laser can be formed as a high-output and low-noise laser without causing any problem in the life and the like of the laser.

Consequently, the projecting upper-step part of the prism 15 is chucked to package the optical integrated circuit to small size and a chuck means contacts none of the principal part of the prism 15, photodetectors 13 and 14, and semiconductor substrate 12 where other circuit elements are formed and the damage can be evaded.
