Title: Formation of circuit pattern
Inventor: YAMAMOTO BUNRO
IPC: B23K26/40
Filed: 1990-09-06
Abstract: PURPOSE:To form a circuit pattern on a circuit board without using an etching process, by a method wherein a conducting layer of the boundary part between a prepared region for a circuit pattern and a prepared region for exfoliation is irradiated with a high density laser light flux, thereby eliminating said layer, and the prepared region for exfoliation is irradiated with a low density laser light flux, thereby exfoliating said layer. CONSTITUTION:A high density YAG laser light flux is converged by using an exclusive optical lens 11, and projected on a circuit board 12, along the boundary part between a prepared region 23a for a desired circuit pattern to be formed on a metal layer 23 and a prepared region 23b for exfoliation. As the result of laser light irradiation, the metal layer of the boundary part only is sublimated, eliminated, and cut. Thereby a boundary trench 13 on the bottom of which a circuit board insulating part 22 is exposed is formed between the prepared regions, and said regions are isolated. The prepared region 23b for exfoliation only is irradiated with a low density YAG laser light flux 20 and heated. As the result of heating, the bond strength of the prepared region 23b for exfoliation of the metal layer 23 of the circuit board is decreased. Only the metal layer or the region 23b is exfoliated by using an exfoliation equipment 14, Thereby the metal layer of the region 23a is left, and a desired circuit pattern 15 is formed.

Title: A/d converter for video signal
Inventor: YAMAGISHI KOJI
IPC: H03M1/12
Filed: 1990-09-07
Abstract: PURPOSE:To generate data similar to (one-plus) data of three bits with simple circuit configuration by using an A/D conversion circuit of three bits, and varying the reference voltage of the A/D conversion circuit only by the minimum reference voltage range at every cycle. CONSTITUTION:The A/D conversion circuit 25 performs A/D conversion by comparing a video signal with the reference voltages Re1-Re7, and outputs the data X1-X3 of three bits. The reference voltages Re1-Re7 supplied to the A/D conversion circuit 25 go to the voltages divided uniformly between a V0 voltage and a V1 voltage. Therefore, when the output signal A of a buffer 22 is inverted at every horizontal cycle, the V0 voltage and the V1 voltage change by (V0-V1/16), and in an interval (a) where the signal A goes to a high level, the voltages V0 and V1 are set higher by (V0-V1/16), and in an interval (b) where the signal A goes to a low level, the voltages V0 and V1 are set lower than that in the interval (a) by (V0-V1/16), correspondingly, the reference voltages Re1-Re7 change by the same level. In such a way, it is possible to generate the data similar to the (one-plus) data of three bits with the simple circuit configuration.

Abstract: PURPOSE: To improve a refrigerant absorbing capacity of an absorber by using the absorber of a constitution for cooling outer surfaces of a plurality of arranged heat transfer tubes with medium such as the air or the like and absorbing a gaseous refrigerant in a tube while allowing an absorbing solution to flow down along an inner surface of a heat transfer tube. CONSTITUTION: When a thick absorbing (lithium bromide aqueous solution) having a concentration of, for example, 60% is fed to a liquid scattering unit 1 and dripped from it to a horizontal peripheral edge of a heat transfer tube A1 in an absorber A, the dripped absorbent flows down along an inner wall surface of a vertical portion of the tube A1 while forming a liquid film, and the absorbent lowers its concentration while absorbing a gaseous refrigerant in the tube A1 . And, a concentration of the absorbing solution flowing down to a bottom of the tube A1 becomes about 59%. Then, this absorbent is fed to a liquid scanning unit 2 by a pump P1 . Thus, a concentration of the absorbing solution arriving at a bottom of a heat transfer tube A4 becomes about 56%.  Thus, a concentration difference between the thick absorbing solution and a thin absorbing solution becomes about 4%, which is the same degree or higher as that of a shell and tube type water-cooled absorber.
