IPC: H01L21/027
Filed: 1987-04-09
Abstract: PURPOSE:To eliminate wastage in a manufacturing process and contrive the low cost of a production by performing a patterning treatment with an implement as a mask for exposure equipped with kind discernment marks. CONSTITUTION:On the occasion of patterning respective processes; the first layer interconnection, an interlayer insulation film, and the second layer interconnection, a mask for exposure is used, while its mask has kind discernment marks 1 and 2, forms of which are mutually similar in their forms or are similar ones where positive and negative relationship is found between them. Then, affirmation of figures located on a semiconductor substrate in each process helps avoid the malfunctions in its process where an upper layer pattern which does not have alignment with a lower layer interconnection pattern is exposed to light and the process in such a state is continued as it is. Thus, the wastage in a manufacturing process is eliminated and the low cost of a production is achieved.

Title: Boiling detecting device
Inventor: MOMOSE IWAO
IPC: F24H1/18
Filed: 1992-04-09
Abstract: PURPOSE:To prevent the boil-over of hot water and to evade the waste of energy due to over heating by detecting the boiling of a liquid with high accuracy. CONSTITUTION:A container 1 is heated by a heating element 2 and the resistance of a negative characteristic thermistor 3 is detected by a temperature detector 4. The detector 4 stores the measured time in a storage means 6 for each rise of the unit temperature through a time measuring means 5 which measures the time required for the detector 4 to rise up to the unit temperature. The value of the means 6 is stored in a fixing means 8 of the means 6 as long as an output signal is outputted from a folding point detector means 7 which outputs the output signal at a folding point (boiling point) of the rise of temperature. Then the value stored in the means 8 is used to a theoretical area storage means 9. A boiling deciding means 11 subtracts the value of a real area storage means 10 from the value of the means 9. The result of this subtraction is identical with the difference between the virtual and actual temperature slopes of the detector 4. This difference is compared with the prescribed value. When the difference exceeds prescribed value, the means decides the boiling and a heating element control means 12 stops the energization of the element 2.

Title: Solid-state laser device
Inventor: SUZUKI MAKOTO
IPC: H01S3/0941
Filed: 1987-04-11
Abstract: PURPOSE:To eliminate the necessity of a condenser device and a cooling mecha nism, by providing excited light feeding devices, which project excited lights into both end surfaces of a laser rod in the longitudinal directions. CONSTITUTION:Excited light R, which is outputted from a first semiconductor laser element 22, is inputted in one end surface 12 of a laser rod 10 through a condenser lens system 24. Excited laser light R, which is outputted from a second laser element 28, is inputted in another end surface 14 of the laser rod 10 through a condenser lens system 30 and a third reflecting plate 26. The fluorescent light is oscillated when the light is amplified during the reciprocating process between a first reflecting plate 18 and a second reflecting plate 20. As a result, part of the laser light, whose phases are aligned, is outputted through the second reflecting plate 20 on the output side. Thus an elliptical-tube shaped condenser device, which condenses the excited light emitted from a light source such as a xenon lamp into the laser rod 10, is not required. A cooling mechanism, which prevents overheating due to the light source, is neither also required.

CONSTITUTION:When an underground membrane 1 is operated, an action of thermal deformation of the membrane caused by temperature changes deriving from operations of cool down, in-out handling of the liquid, warming up, etc. is ineviatbly followed. However, in a bottom membrane 8 of the tank 1, an expansion and contraction in the intersection of each corrugation and a turning of the flat plate part are uniformly performed because a uniform module forming is applied to corrugations 101, 102,...10n, radial corrugations 11, 11', 11'' and an arrangement of flat plate parts 14-16, and even in a center part 9 an irregular portion is not generated for a reason that in the surroundings of a pentagonal flat plate part in the center the other two kinds of triangular and tetragonal flat plate part are arranged. Accordingly, a generation of deflected thermal stress, deflection in the center and its resulting irregular turning is not caused also without a concentration of stress to the above described intersection.
