Title: Thermal head
Inventor: FUJII KAZUKO
IPC: B41J2/335
Filed: 1980-12-24
Abstract: PURPOSE:To eliminate nonuniformity in concentration by forming the same plated metal as common electrodes formed on a long edge part even on common electrodes formed on a short edge part of a ceramic substrate, thereby increasing the thickness of the common electrodes and decreasing the electric resistance. CONSTITUTION:On the ceramic substrate 1, a resistive heating body 2, a common electrode 7, and a protecting film 8 are formed. Thereafter the plating is performed on the common electrode 7 in order to increase the thickness of the common electrode 7 and to decrease the electric resistance. When the protecting film 8 is formed on the common electrodes 7c and 7d, the resistance values at those parts are not decreased, the heating value at the resistive heating body 2 connected to the common electrode 7a becomes different from the heating value of the resistive heating body 2 connected to the common electrode 7b, and the nonuniformity in concentration is yielded in each dot. Therefore, the configuration is designed so that the protecting film 8 is not placed on the common electrodes 7c and 7d. Thus, the difference in concentration of each dot is eliminated, and the recording with uniform concentration can be accomplished.

Abstract: PURPOSE:To always accurately focus a lens on a prescribed position by attaching a variable focus lens means, a distance measuring means, and a focus control means, which operates the variable focus lens means based on measured distance information of the distance measuring means, to a frame of spectacles. CONSTITUTION:A light source 6 attached to a spectacle frame 1' of spectacles radiates an infrared luminous flux by a power source 2 attached to the other spectacle frame 1, and this luminous flux is projected to an object and is reflected and is detected as the reflected luminous flux by a light receiving device 7 attached to the spectacle frame 1 to measure the distance to the object. The luminous flux from the light source 6 is reflected at a point P on an object A and passes a lens 8 and is received at a point P' on a position sensor 9. In case an object B to which the distance is different from that to the object A is considered, the luminous flux is reflected at a point Q and is received at a point Q' on the position sensor 9, and positions of both points P' and Q' are calculated as subject distances by a processing part in the device 7, and subject distance information drives variable focus lenses 3 and 3' to obtain proper lens focal lengths. Thus, auto-focusing is possible.
