Title: Fluorescent lamp
Inventor: WATABE HIROSHI
IPC: H01J61/067
Filed: 1985-02-06
Abstract: PURPOSE:To prevent brightness appearing around the electric poles from making irregular variation by pinching a filament coil with two lead wires, and setting the electric poles with their filament coil terminal portions outside the lead wires bent to the discharging sides. CONSTITUTION:Filament 1 with its double coiled portion (a) to which an oxide is applied on almost all the surface is pinched with lead wires 2, 2', filament terminal portions b, b', outside the lead wires 2, 2', are bent almost perpendicularly to the discharging sides. Here, the tips of the filament terminals b, b' are projected enough to the discharging sides beyond the top portions C, C' of the lead wires 2, 2' and the secondary coil portion (a) of the filament 2. With this constitution, a lamp is prevented from flickering for a long period of lighting. This is due to the fact that fluctuation in electron current distribution does not take place, even though the exposed surface of the metal portion of the filament is increased through gradual consumption of the oxide of the electrode, based on the charactristics that thwn the pole is positive, electrons steadily flow onto the projecting end of a filament.

An electric conduction quantity of a heating resistor 402 is increased, it is set to an isotropic phase by heating of a heater of the first stage of a high heating value, and thereafter, cooled slowly under a temperature gradient. This slow cooling reduces an electric conduction quantity to the heating resistor 402 forms SmA by heating of a heater of the second stage of a low heating value, and thereafter, the temperature gradient is released, and also the liquid crystal 401 is phase-transferred to SmC* by heating of a heater of the third stage of a low heating value.

Filed: 1983-02-12
Abstract: PURPOSE:To permit simple and certain altitude-compensation by introducing the air into an acceleration pump which communicates to the float chamber of a carburetor and is operated by the negative pressure in an intake pipe, in accordance, with the decrease of the atmospheric pressure and suspending the operation of the acceleration pump at highland. CONSTITUTION:When a car equipped with an internal-combustion engine is used at highland, the bellows 14 of an altitude compensation control valve 13 is extended as the atmospheric pressure and the air density decrease, and a valve 16 is pushed-down against the pressing force of a spring 17, and an air intake port 21 is opened. Therefore, air is introduced through an air filter 15 and further introduced into the diaphragm chamber 8 of an acceleration pump 4 through a passage 18. Though also the negative pressure in an intake pipe 20 is introduced into the passage 18 at this time, said negative pressure is bleeded by the air, since a throttle 19 is equipped. Therefore, a diaphragm 7 is kept in standstill state, and the acceleration pump 4 stops operation and does not deliver fuel. Thus, deterioration of driving performance due to the concentration of the mixed gas is prevented.

IPC: G11B5/85
Filed: 1998-02-02
Abstract: PROBLEM TO BE SOLVED: To improve production efficiency by preventing the generation of splashes in a crucible by falling of a large amt. of vapor deposited matter into this crucible and further taking the wide area of an aperture formed by deposition preventing plates.
