Title: Exposure device
Inventor: SEKIYA TOMOJI
IPC: H01L21/027
Filed: 1989-12-28
Abstract: PURPOSE:To enable throughput to be improved by allowing an exposure light to be incident to a reflection projection optic system through a mask and by allowing the exposure light to be radiated from here to be branched for irradiating light to each wafer which is placed at an image-forming position in the reflection projection optic system. CONSTITUTION:In a branching optic system 20, 1/3 of entire amount of light from a reflection projection optic system 17 is reflected from a beam splitter 21 and is irradiated onto a wafer 13 and 1/2 of the remaining 2/3 is reflected from a next beam splitter 22 and is radiated onto a wafer 14. Further, the remaining exposure light is reflected from a plane mirror 23 and is radiated onto a wafer 15. At this time, a mask 12 and wafers 13-15 are synchronized, are moved in the direction of an arrow square and are scanned over the entire region of the pattern, and the pattern which is formed at the mask 12 is transferred to the wafers 13-15, thus improving the throughput.

Title: Video conference system
Inventor: MURAKAMI KOJIRO
IPC: H04M3/56
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To enable remote instruction/plotting or remote camera position control even with a communication terminal used only for image/voice by superimposing a pointer or a line drawing for displaying position information onto a moving image in order to exchange the position information. SOLUTION: A picture B as the moving image from a terminal B is sent from a communication control part 31 to an instructed object recognizing part 32. The instructed object recognizing part 32 discriminates a pencil P in the picture B in cooperation with an instruction/plotting recognizing part 35. An instructed object position information extracting part 33 and an instructed object motion information extracting part 36 discriminate the position and motion of pencil P, which is recognized by the instructed object recognizing part 32, on the image. The discriminated position and motion information of pencil P is sent to a position/motion synthesizing part 34. Based on the position/motion information of pencil P, a pointer image P formed in the shape of arrow is superimposed on a moving image A, which is photographed by a video camera 1, by the synthesizing part 34.  That superimposed moving image is transmitted as a moving image through the communication control part 31 to the video conference terminal B. At the same time, this moving image is displayed on a video monitor 3 as well.

Title: Control circuit for lamp color variable head lamp
Inventor: HAYAMIZU HISAFUMI
IPC: B60Q1/20
Filed: 1993-12-24
Abstract: PURPOSE:To prevent the colors. of right and left head lamps from being different from each other when a driving device fails, by aending out a trouble signal to a lamp color switching means when a trouble detecting means detects a switching trouble of the head lamps. CONSTITUTION:A brush 9a short-circuits patterns 8a and 8b provided on a substrate, and is moved linearly integrally with a rack of a yellow globe to switch the colors of the head lamps into white or yellow color. Because the left end of a resistance 2d is grounded through a diode 10a or 10b while the brush 9 is moved, the base of a transistor 14 as a trouble detecting means becomes L level, and thus a relay 11 is deenergized. As a result, the contacts 11b becomes off, and the head lamps are turned off. Thus, because the head lamps are turned off while the brush 9 is moved, that is, a yellow globe is in operation, the troubled head lamp does not light, and the colors of the right and left head lamps are not different from each other, even when a driving system fails while the brush 9 is moved, and is stopped in place.

Title: Resistance diffusion joining method
Inventor: INOUE SHINICHIRO
IPC: B23K1/00
Filed: 1991-12-27
Abstract: PURPOSE:To join joining members at low energy and to maintain the prescribed shearing force by interposing at least two kinds of insert materials varying in m.p. on the joint surfaces between the joining members, then joining these members. CONSTITUTION:The second joining member 4 is imposed via a plating layer 2 and brazing filler metals 3a, 3b on the joint surface of the first joining member 1. While the joining members 1, 4 are pressurized, the members are energized to induce resistance heat generation, by which the brazing filler metals 3a, 3b are melted and the members are joined. Since these members are joined by at last two kinds of the different insert materials 2, 3a, 3b, the m. p. is lowered by a m. p. lowering effect. The amt. of the brittle compds. to be formed is therefore decreased and the degradation in the shearing force is suppressed.
