Title: Light beam scanning device using rotary polygon mirror
Inventor: WATANABE KATSUTO
IPC: G03G15/04
Filed: 1986-07-09
Abstract: PURPOSE:To monitor the rotating operation of a rotary polygon mirror even in a nonprinting state where a shutter is closed by providing a photodetecting element which detects a scanning beam nearby a scanning end part in front of the shutter. CONSTITUTION:The shutter 40 is arranged in front of a photosensitive body 41, and the shutter is closed not to expose the photosensitive body 41 to zero- order light when printing operation is not performed and then opened when printing operation is performed. The photodetecting element 44 which outputs a horizontal synchronizing signal, on the other hand, is arranged in front of the shutter 40, so the element outputs the horizontal synchronizing signal as long as the scanning light beam is reflected by the rotary polygon mirror 37 regardless of whether or not the shutter 40 is open and whether or not the printing operation is performed. Consequently, the rotating operation of the polygon mirror 37 is monitored even in the nonprinting operation where the shutter 40 is closed by measuring the period of the horizontal synchronizing signal outputted by the photodetecting element 44.

Filed: 1982-09-17
Abstract: PURPOSE:To form a fine resist pattern quickly by a method wherein a photosensitive film has a double-layer composition of a photo-luminescent layer and a photosensitive layer and radiation is applied to the photosensitive film. CONSTITUTION:When electron beam radiates, the injected electron beam 21 reaches a photosensitive thin film 23 such as resist after passing through a photo-luminescent layer 22. The electron beam 24 injected into the resist 23 reduces its speed while passing through the photo-luminescent layer 22 but it has enough energy to pass through the resist 23 and it can operate chemical reaction such as decomposition or polymerization. On the other hand, energy absorbed by the photo-luminescent layer 22 while the electron beam passing through the layer 22 generates a secondary radiation beam 25. For instance, if the layer 22 is a fluorescent layer, excitation by the electron beam generates light beam. In this case, a fluorescent material which radiates light beam whose wavelength is less than 500mum must be chosen to expose the resist 23.

Title: Solder remover
Inventor: WATANABE HIROSHI
IPC: B23K1/018
Filed: 1981-10-13
Abstract: PURPOSE:To suck away molten solder easily with a small-sized and easy to handle solder remover by mounting a suction nozzle to a case body, making a suction pump built in and interposing a filter between the nozzle and the pump. CONSTITUTION:When a switch is turned on, a suction nozzle 3 evolves heat. The operator brings this nozzle 3 into abutment on the solder to be removed to melt said solder and pulls an operating piece 32 in the direction of an arrow 38. The bottom end of an interlocking piece 30 is then pressed, by which a sliding rod 27 is slided horizontally and a rod 26 is moved as well. Thereupon, a piston 25 moves in a cylinder 21 and the air in a suction hole 20 is sucked in the direction of an arrow 44. Therefore, the inside of a connecting pipe 19 and a filter cylinder 9 is evacuated and the inside of a suction pipe 5 is evacuated as well. When the preceding end of the nozzle 3 contacts with the molten solder, the solder is sucked easily as shown by an arrow 45, and enters the inside of the filter cylinder 9. The molten solder passes through a metallic hairy body 17 and a felt layer 15 and is sucked into the pipe 19. Since the solder is heavy, it sticks on the head part 12 of a mounting rod 13. The operator removes the filter 9 by rotating a knob 7, and removes the solder by blowing air to the filter lightly.

Filed: 1999-06-10
Abstract: PROBLEM TO BE SOLVED: To provide a device capable of realizing high luminance in the case of using it in the daytime, and low luminance and large display size in the case of using it in the night. SOLUTION: In this display, a lamp 3 is not lit but a fluorescent tube side light type backlight 2 is used in the night when the low luminance is required. Since transmission characteristic is given to one part of a backward diffuse reflection plate 23, the part of light from a fluorescent tube 21 going toward the plate 23 reaches the lamp 3, and most of the light is reflected by the reflector of the lamp 3 and finally goes toward a liquid crystal panel 1, so at the loss of the light is restricted to very small quantity such as only the light absorbed by the lamp part. Then, the backlight 2 is not lit but the lamp 3 is lit in the daytime when the high luminance is required. The light from the lamp 3 is transmitted through the plate 23, diffused and guided to the panel 1 in a state where in-plane uniformity is improved.
