Patent JP-S6467502-A (JP)
Title: Steam generator
Inventor: KOTAKA IKUO
IPC: F22B37/26
Filed: 1987-09-08
Abstract: PURPOSE: To ensure stable operation even when load variations are severe by disposing a steam/liquid drum upward from a lower header and downward from an upper header. CONSTITUTION: A steam/water drum 16 is disposed upward from a lower header 3 and downward from an upper header 4, and a liquid level in a heat transfer pipe 2 is located at a middle position, so that the heat transfer pipe 2 is heated and liquid in the heat transfer pipe 2 is expanded to raise the liquid level, and even when temperature of the liquid in the heat transfer tube 2 reaches certain temperature to produce bubbles of steam, the liquid level in the steam/ water drum 16 is prevented from being raised.  In stationary operation, bubbles of steam scatter the water in the heat transfer tank 2 to an upper portion of the heat transfer tube 2, and most part of the scattered water is vaporized, so that a water volume reaching the steam/liquid drum 16 is one of several tens of the produced volume of the steam, and hence even when a load is varied and the produced volume of the steam is changed and hence the liquid surface in the heat transfer tube 2 is raised or lowered, the liquid level in the steam/ liquid drum 16 is not substantially varied. Thus, even when a load is varied, stable operation is ensured.

Filed: 1983-11-26
Abstract: PURPOSE:To increase the strength of the joining layer by shaping the surface of one of the members to be joined so that the surface will be closely fitted to the surface of the other member when the vessel is in a distorted state, and by adhering these surfaces applying a pressure to the members to be joined from the outside. CONSTITUTION:Members to be joined 5, 6 are fitted together to form a vessel and the fitted glass vessel is baked to adhere the members 5, 6, with forces applied in the directions indicated by the arrows 8, 9 to the vessel from the outside of the members 5, 6. The force applied from the outside should have a magnitude which will cause the same amount of bending of the vessel as that generated when the glass vessel is evacuated. Furthermore, at least one of the surfaces of the members to be joined is shaped so that it will make a tight contact with the other surface, when the glass vessel is bent because of the forces applied from the outside. For example, the shape of the surface to be joined of the member 11 is adjusted to adhere to the surface of the member 10, as shown in the diagram.

Title: Circuit pattern inspecting device
Inventor: TANIGAWA TORU
IPC: G01N21/956
Filed: 1990-08-24
Abstract: PURPOSE:To make precise inspection of a miniature circuit pattern by introducing automatic adjustment so that the circuit pattern lies at the focal point of a photographing means. CONSTITUTION:A film type transistor base board 10 is fixed to an inspection stage 20, and reference marks 12, 12' provided on a clear basis 13 of this base board 10 are photographed by cameras 31, 31', and the image signal obtained is entered into a CPU 50 through a reference mark sensing part 33. The CPU 50 calculates the dislocation of cameras 31, 31' from the marks 12, 12' and moves the inspection stage 20 so that the circuit pattern 11 on the base board 10 confronts a pattern inspecting camera 41 of a photographing means 40. A dislocation sensing means 80 irradiates the pattern 11 with a slit light and senses dislocation of the pattern 11 from the focal position of the photographing means 40 on the basis of the reflecting position in this irradiation, and a dislocation correcting means 70 changes the distance between a camera stage 60 and the inspection stage 20 so that the pattern 11 lies at the focal position of the photographing means 40. Thus the means 40 photographs the pattern 11 in focused condition, and any defect in the pattern 11 can be sensed by processing 90 the image obtained.

Title: Production of light guide
Inventor: AKITA OSAMU
IPC: G02B6/134
Filed: 1987-09-07
Abstract: PURPOSE:To form a waveguide layer which has excellent reproducibility and uniform quality by bringing the vapor or liquid drops of a proton exchange source into contact with the surface of an LiNbO3 substrate to effect the proton exchange of the LiNbO3 substrate, thereby forming the waveguide layer. CONSTITUTION:The LiNbO3 substrate 4 is housed together with benzoic acid powder as the proton exchange source 2 into a vessel 1 and is heated for the prescribed period. The evaporated exchange source 2 is thereby brought into contact with the surface of the substrate 4 and the proton exchange is executed. The vessel 1 is thereafter taken out of a thermostatic chamber and is cooled. The vapor or liquid drops generated from the exchange source are thereby extended to all the corners of the surface of the substrate 4 and the proton incorporated in the exchange source 2 is brought into contact with the Li ions of the substrate 4, by which the proton exchange is executed. Since the vapor or the liquid drops has high flowability, the vapor or liquid drops are successively replaced with the fresh vapor or liquid drops without stagnating on the surface of the substrate 4. The uniform waveguide layer is thereby formed.

IPC: B23P19/04
Filed: 1984-10-23
Abstract: PURPOSE:To enable a coil spring to be automatically incorporated, while making direction setting of both end hooks of the spring by employing a process of moving the hook portions of a spring loaded in the slot of a reciprocally moving spring receiver block, along a slope and turning into its horizontal attitude. CONSTITUTION:A spring 4 supplied through a supply tube 3 drops into a V-shaped slot 7 when a reciprocally moving spring receiver block 6 comes to the left end of reciprocal motion. While the spring receiver block 6 moves rightward, the spring 4 rotates resulting from contact of the hook portion 4a of the spring 4 with the slope 8a of a slope guide 8. This rotation continues until the hook portion 4a fully comes into contact with the slope 8a, but stops thereafter, and the hook portion 4a slips to a horizontal plane 8b adjacent to the slope 8a. When the spring 4 rotates until the overall portion of hook 4a comes into contact with the horizontal plane 8b, direction setting of the hook 4a finishes. When the spring receiver block 6 stops motion, the spring 4 is held in a position determined by the top of a holder plate spring 12 located above.

Title: Soldering method
Inventor: OKADA HIROYUKI
IPC: H05K3/34
Filed: 1988-09-07
Abstract: PURPOSE:To prevent the occurrence of short circuits of solders by printing neighboring solder pastes on foot-print patterns which are aligned and formed on a printed board in a zigzag pattern, and performing soldering. CONSTITUTION:A plurality of rectangular foot-print patterns 2 are aligned and formed at an equal interval on a printed board 1. About one half of the length of each solder paste pattern 3 covers about one half of the length of the foot-print pattern 2. The neighboring patterns 3 in the alignment cover the patterns 2 in this way in a zigzag state. Therefore, there is no narrow facing surfaces between the solder paste patterns 3. The entire solder paste patterns 3 are heated with steam and fused. At this time, the solder moves in the direction where the solder paste patterns 3 are not printed and soldering is performed. The extrusion of the solder into the lateral direction is less. Thus the short circuits between the neighboring patterns can be prevented.
