摘要:
A sealing and pump-up device capable of suppressing sealing agent contained in a sealing agent container body from leaking and preventing damage to a casing body even if an operator mistakenly attempts to remove the sealing agent container body. A connection body 70 is retained to a seal opening device 60 by fitting force between first claws 94A and a leg portion 36 and between second claws 96A and the leg portion 36. An operator might conceivably mistakenly attempt to remove a liquid agent container 18 from the seal opening device 60. However, the fixing force of the screw 128 in the circular hole 122 is determined by such factors as the shape of each member so as to be weaker than the sum of the fitting force (retaining force) between the first claws 94A and the leg portion 36 and the fitting force (retaining force) between the second claws 96A and the leg portion 36. Accordingly, fixing of the screw 128 in the circular hole 122 is released if an operator attempts to remove the liquid agent container 18 from the seal opening device 60, and the sealing agent 32 contained in the liquid agent container 18 can be suppressed from leaking and damage to the casing body 16 can also be prevented.

A polyacetal resin composition comprising 100 parts by weight of a polyacetal polymer, 0.01 to 0.5 part by weight of a hydrazide compound, 0.01 to 0.1 part by weight of an amino-substituted triazine compound and 0.01 to 5 parts by weight of a hindered phenolic compound, wherein the resin composition has a total content of hydroxides, organic acid salts and inorganic acid salts of an alkali metal and an alkali earth metal of 50 ppm or less by weight in terms of the total of the alkali metal and the alkali earth metal; and a molded article thereof. The polyacetal resin composition greatly suppresses the emission of formaldehyde from a pellet or molded article thereof and rarely produces a mold deposit.
摘要:
A low-pressure discharge lamp having a tubular glass lamp vessel 10, on an outer surface of which conductor layers are formed as electrodes 21 and 26. The ultrasonic solder dipping layers 31 and 36 are formed at both ends of the vessel 10 as conductor layers. The end surfaces of the glass lamp vessel are blasted and ultrasonic solder dipping layers are formed on the blasted surfaces 41 and 46 by ultrasonic solder dipping. Conductor layers forme external electrodes 21 and 26, which are in contact with the glass surface more strongly. A low-pressure discharge lamp having the conductor layers of a uniform thickness can be mass-produced at low cost.
摘要:
An air conditioner capable of improving its assembling efficiency and reducing material costs. The air conditioner reduces the effects of the fluctuation in commercial line voltage (12) on the supply voltage to a compressor (11), while reducing the vibrations of its outdoor unit (2). The outdoor unit (2) is provided with a voltage correction circuit (14) that maintains the output voltage to the compressor (11) constant (optimal) regardless of the changes in voltage on commercial power supply line (12).

It is an object of the present invention to provide an operation control method of an air-conditioning apparatus and an air-conditioning apparatus that prevent a plurality of air-conditioning apparatuses from simultaneously restarting upon their automatic recovery after a recovery of power and from stopping again due to a voltage drop. The air-conditioning apparatus of the present invention is provided with an automatic recovery control circuit (21) for deciding a delay time until a restart based on set data for deciding operation works of the air-conditioning apparatus or randomly, thereby to restart the air-conditioning apparatus with the decided delay time.

A polyamide resin which comprises a molten reaction mixture composed of 10-90% by weight of a polyamide (A1) from xylylenediamine and a C.sub.6 -C.sub.20 .alpha.,.beta.-linear aliphatic dibasic acid and 90-10% by weight of polyamide-6 (A2). The polyamide resin has either a single glass transition temperature differing from that of both (A1) and (A2), or two glass transition temperatures both differing from those of (A1) and (A2), the difference between the two temperatures being less than 10.degree. C. There are also provided a toughened polyamide resin composition comprising (A) 100 parts by weight of the polyamide resin, and (B) 5 to 80 parts by weight of an elastomer such as one composed mainly of a block-copolymerized elastomer which has been modified with an unsaturated dicarboxylic acid or a derivative thereof and hydrogenated.
摘要:
In a method for controlling a fuel injection amount of an internal combustion engine of the present invention, an incremental fuel amount is calculated in accordance with an engine running condition when a high load state of the engine is detected, and an upper limit value of the incremental fuel amount is gradually increased at predetermined intervals. When the incremental fuel amount is equal to or lower than the upper limit value, the fuel injection amount is increased to the extent of the incremental fuel amount. When the incremental fuel amount exceeds the upper limit value, the fuel injection amount is increased with the upper limit value. With this controlling method, the fuel consumption efficiency and acceleration response can be improved and the generation of knock in the engine can be suppressed during the period of the increase of the fuel injection amount in the high load state.
