Title: Video recording reservation controller
Inventor: SHIMOIDE TAKASHI
IPC: H04N21/472
Filed: 1999-04-15
Abstract: PROBLEM TO BE SOLVED: To facilitate a program reservation method by a bar code. SOLUTION: Reservation is finished only by displaying program contents from information fetched from the outside by an input means on a TV receiver in a list form as shown in figure with a display control means and selecting the required program contents by operating a positional specification means and a setting means. In such a manner, since, the necessity for tracing the bar code with a bar code reader is eliminated in program reservation, the trouble that the bar code is not read even when the bar code is traced by the for a number of times is solved. Moreover, since the program contents are displayed in the list form, a required program is set while comparing with front/rear, left/right programs. Thus, even when the program of a name similar to each other exists, a reservation miss due to a mistake hardly occurs.  Further, like a technique before the appearance of a bar code reader, the necessity for setting a channel is eliminated also, and the trouble for inputting a start time is eliminated also. Thus, operation is remarkably simplified.

Title: Heat-sensitive recording apparatus
Inventor: SETOYAMA YOUICHI
IPC: B41J2/355
Filed: 1983-06-16
Abstract: PURPOSE:To cut down bonding lines for clearer recording, by installing a plurality of gate-circuits controlling current supply time for printing of output of the first latch circuit group through the second controlling signal of current supply time for printing. CONSTITUTION:A gate circuit 24, when the first as well as the second current supply time for printing controlling signals (d) and (e) take both 1 position respectively and a printing information of the second latch circuit 25 is significant, regardless of a printing information of the first latch circuit 26, its output signal during the time t2 takes 0, does not supply an electric current to a heat-generating resistor 21 by a driving circuit 23. Reversely, this circuit 24, when the second printing information of latch circuit 25 in insignificant, actuates a driving circuit 23 corresponding to a printing information of the first latch circuit 26 and supplies current selectively to the resistor 21. Thus, for continued significant informations, super-heating of the heat-generating resistor can be prevented for only a period of t2, by suspension of current to the resistor, without added installations of strobing signal lines.

Title: Laser beam processing method
Inventor: MIYAUCHI TAKEOKI
IPC: B23K26/16
Filed: 1986-05-14
Abstract: PURPOSE:To prevent the surface contamination around a working part by irradiating laser light on the surface of a work object after forming a thin dielectric film thereon so that the material to be removed by melting the work object is splashed far off. CONSTITUTION:The laser light 1 is condensed by a condenser lens 2 and is projected on the working part 3 of a work piece 5 on a substrate 4 consisting of Si, glass, etc. A thin film material having such high mechanical strength as to hinder the removal of the work piece 5, for example, a pressure intensifying film 6 consisting of Si3N4 or SiO2 is preliminarily formed on the work piece and therefore, the process of melting, evaporating and splashing the material to be removed does not easily arise. The pressure intensifying film 6 is destructed at the point of the time when the mechanical strength of the pressure intensifying film 6 is exceeded. As a result, the melted and splashed material is splashed far off by the strong pressure and is cooled in the midway, by which the adhesive power to a peripheral member of the dropping material is decreased. The deposits to remain after cleaning are thus decreased and the residual contamination is lessened.
