Filed: 1956-01-09
Abstract: 794,286. Captive balloons. LEA BRIDGE INDUSTRIES, Ltd. Nov. 1, 1956 [Jan. 9, 1956], No. 688/56. Class 4. A captive balloon comprises an envelope 1 which is a body of revolution about a tube 3 connecting upper and lower surfaces. The body 1 is surrounded by a further inflatable compartment 4 provided with peripheral vanes 5 which, under surrounding air movements, cause the balloon to rotate about an axle 2 secured in tube 3 by bearings 6. The lower end of the axle is connected by a universal joint 9 to a mooring cable 8. A radar cupola 7 may be supported by the cable which would then be provided with a further universal connection 10. The rotational movement of the balloon imparts stability thereto and this may be further assisted by increasing the centrifugal effect by filling the compartment 4 with a gas heavier than that used for the body 1.

Patent JP-H06204402-A (JP)
Title: Manufacture of semiconductor device
Inventor: WATANABE KENJI
IPC: H01L27/04
Filed: 1993-01-05
Abstract: PURPOSE:To simplify processes for forming an electrode of a capacitive section whose surface area is increased by making a surface thereof rugged, and to increase an electrostatic capacity of the capacitive section. CONSTITUTION:An SOG film 4 is formed on the surface of a silicon film (HSG silicon film) 3 on the surface of which hemispheric grains are provided. This is then etched back, so that the peaks of the grains on the surface of the HSG silicon film are exposed. Then, the SOG film 4 is left at depressions between the peaks. The HSG silicon film 3 is subjected to anisotropic etching using the SOG film 4 as a mask, whereby a lower electrode possessing pillar-like projections or holes is formed. Thus, the lower electrode can be directly etched by means of the SOG film 4, and hence processes for forming the lower electrode can be simplified. Moreover, the depressions of the grains on an upper surface of the lower electrode also contribute to an increase in surface area, which increases an electrostatic capacity.

Title: Magnet type generator for vessel engine
Inventor: YUMIYAMA SHIGERU
IPC: H02K21/22
Filed: 1989-01-06
Abstract: PURPOSE:To increase generator output without causing degradation of stable rotation of engine by employing three-phase generating system in a magnet type generator for a vessel engine. CONSTITUTION:Upon rotation of a rotor 2 fitted to the vessel engine crankshaft of a three-phase generator 1, AC currents 4a, 4b, 4c are produced in generating coils 3a, 3b, 3c of respective phases. The AC currents are rectified through a rectifier 5 and output current 6 is taken out. Alternating fluxes 7a, 7b, 7c are generated in the generating coils 3a, 3b, 3c through the AC currents 4a, 4b, 4c thus producing force for varying the rotation of the rotor 2. Since the generating coils 3a, 3b, 3c are wound similarly, alternating fluxes 7a, 7b, 7c are cancelled and the force for causing variation of rotation of the rotor 2 is not produced.

The output signal 47 of the gate 46 and reactor water level high signal 48 which is activated when the water level in the reactor pressure vessel is higher than a main steam line nozzle, are input to the AND circuit 49. If both conditions agree, this circuit 49 outputs a termination signal 50 of low pressure emergency core cooling system. When the temination signal 50 is actuated, the water injection and water level rise are terminated and the boric acid is kept in the core without flowout of coolant.

Abstract: PURPOSE:To enable to perform a multicolor recording by a low-power capacity, by a method wherein, in a recorder which conducts a multicolor recording by a plurality of thermal heads, a drive current to each thermal head from a power source is supplied by a time division. CONSTITUTION:When a recording paper reaches a red color recording part, a picture signal 21A for red color recording is supplied to a sink drive 19A at a given timing.
