Title: Turbine generator
Inventor: SAKAKIDA HITOSHI
IPC: F01D25/28
Filed: 1984-11-22
Abstract: PURPOSE:To enhance the vibration-resistance of a turbine generator, by securing the leg section of an upper plate on which a generator body is supported, on a base mat, and by providing a vibration damping member to the leg section to decrease the responsive displacement of the entire turbine generator upon earthquake. CONSTITUTION:In a turbine generator in which a generator body is supported on a upper plate which is secured to a base mat through the intermediary of a leg section 10, a steel damping plate 16 is arranged on the outer peripheral side of each of side plates 12 constituting the leg section 10. The side plates 12 are not completely secured to the damping plate 16 so that they are slidable relative to each other when they are deformed. When the entire system of the turbine generator oscillates upon, e.g. earthquake, the side plates are deformed so that the side plates and the vibration damping plates 16 are slid, relative to each other while the side plates 12 and the damping plates 16 slide relative to each other while they are made in contact with each other so that a force which prevents the sliding thereof is effected on their contact surfaces. With this arrangement the displacement of the entire system may be made to be small.

Title: Ceramic discharge lamp
Inventor: OKAMURA KAZUYOSHI
IPC: H01J61/34
Filed: 1991-09-25
Abstract: PURPOSE:To prevent breakage due to heat by reducing the rate of overheating in the bend of a light emitting tube even though the bend causes eccentric existence of arcs. CONSTITUTION:A light emitting tube 5 made of ceramic is accommodated in an outer tube 1 and fitted with electrodes 7, 7 at the two ends, and a U-bend 9 is formed between these electrodes. This light emitting tube 5 of a ceramic discharge lamp is so structured that the intersecting angle theta of the tangents drawn from the tips of the electrodes 7, 7 so as to contact the inner wall of the bend 9 exceeds 40 deg. Exceeding 40 deg. lessens the arc contacting area with the inner wall at the inside of tube bend, which should prevent overheat of the tube.

Title: Pattern forming method
Inventor: ETSUNO NAGAAKI
IPC: G03C5/56
Filed: 1983-12-24
Abstract: PURPOSE:To form a fine pattern without using any photoresists by making the thickness of a thin film which is made amorphous thin so that the crystallization of fine particles can be effected even at the interface between the amorphous thin film and a substrate by the irradiation of a light beam to the amorphous thin film of an inorganic material, throttling the light beam into a small spot, and irradiating. CONSTITUTION:A vitreous substrate 1 which is sufficiently polished and washed is placed in a vacuum device 6. An alloyed material 8 of Te, Ge, and Sn is put in a tungsten boat 7 while rotating the substrate 1, and vacuum vapor-deposited to form a thin film 9 of Te, Ge, and Sn. The substrate 1 is placed on a revolving stand revolving at high speed, and the focused light beam from an Ar ion laser is modulated and irradiated on the surface of the thin film. A fine nucleus is grown on the part of the thin film 9 irradiated with the light, the transmittance of the light is decreased, and the reflectivity is increased. Accordingly, the phase transition into a crystal phase occurs. Then the thin film 9 is etched by plasma. Since the etching speed of the part crystallized by the light irradiation is extremely low, or 1/3-1/10 times the speed of the part not crystallized, protrusions are generated on the vitreous substrate 1 in accordance with the pattern irradiated with the light, and so-called negative pattern having recesses and protrusions are formed.

IPC: C21C5/44
Filed: 1983-12-28
Abstract: PURPOSE:To detect exactly the residual thickness of the refractory wall of a converter as well as the transition thereof with time and to discover the abnormal wear of the refractory wall in an early stage by detecting the fluctuation in the temp. during one cycle of the operation including the time while the furnace is empty by the thermocouples embedded in the refractory walls in the stage of operating the converter. CONSTITUTION:Thermocouples A are embedded into the refractory wall of a converter at 100-150mm. space from the inside wall and the temp. during refining when the cycle consisting of raw material charging, refining and tapping is repeated increases as shown in the curve I in the stage of operating the converter. When the inside of the furnace after tapping is empty, the temp. falls like the curve II and the temp. difference DELTAT is detected during this time. The temp. is compared with the value DELTAT calculated preliminarily from the relation between the heat conductivity of the refractory wall and the distance from the inside surface of the refractory wall to the position A and the distance DELTAL from A to the inside surface of the refractory wall is exactly estimated. The danger for the erosion of the furnace wall owing to the abnormal wear of the refractory wall is predicted therefrom and a countermeasure is effected.

Title: Digital control apparatus for inverter
Inventor: KODAMA TAKASHI
IPC: H02P27/06
Filed: 1992-09-17
Abstract: PURPOSE:To avoid troubles in sudden change of control conditions by slowly changing the control state even when the changing width is large when the constants of control operation is set and changed during operation by providing cushion processing parts in the output stage of an input-data processing and operating part. CONSTITUTION:When the various kinds of constants for control operation are set and changed during operation, the operator inputs the setting and changing values from a digital setting device 5. The setting and changing values are processed with an input-data processing and operating part 6. The values are outputted into the specified respective operating parts, i.e., a speed-control operating part 1, a vector-control operating part 2 and a PWM operating part 3. At this time, relaxation processing is performed with cushion processing parts 62-l, 62-2 and 62-3. The output value, which is outputted into each operating part, is gradually changed. Even if the changed width of the setting and changing value is large, the control-state is smoothly changed. Therefore, the operator can set the value into the digital setting device 5 without special consideration for the magnitude of the changed width when the setting and changing values are inputted.
