A sub tank is provided that includes a case at which an air flow path is formed, the air flow path including an entrance flow path portion that is connected to an ink accommodating portion of the case, and a cross flow path portion that continues from the entrance flow path portion. The cross flow path portion extends in an upper diagonal direction with respect to a reference plane corresponding to the ink liquid level at a standstill state. Another sub tank is provided that includes a case forming an ink accommodating portion, on which case a flexible film member is attached through bonding or welding to seal an opening of the ink accommodating portion and to form one side of the sub tank. A spring is disposed within the ink accommodating portion between the case and the flexible film member, the spring forcing the flexible film member outward.

A display device consisting of an electron-emitting device which is a laminate of an insulating layer and a pair of opposing electrodes formed on a planar substrate. A portion of the insulating layer is between the electrodes and a portion containing an electron emitting region in between one electrode and the substrate. Electrons are emitted from the electron emission region by a voltage to the electrodes, thereby stimulating a phosphorous to emitting light.

The present invention provides a method of manufacturing an image display device in which a panel member constituting a panel of an image display device is transferred to a plurality of processing chambers each comprising a temperature control unit, and subjected to a plurality of processing steps under temperature control. The pressure in each of the plurality of processing chambers is set to be not more than that of the previous processing chamber of the transfer process.
摘要:
A method and an apparatus of manufacturing an image displaying apparatus having an electron source substrate and a phosphor substrate. The electron source substrate is provided with an electron emitting element formed by covering with a container and by applying a voltage to an electronic conductor on the substrate. While, the phosphor substrate is provided with a phosphor thereon. The substrates are subjected to a getter processing and to a seal bonding process under a vacuum condition through a processing chamber, to complete an image forming apparatus. An improvement resides in miniaturizing and simplifying operation, and in greater manufacture speed and mass production.
摘要:
A substrate for an electron source, the substrate including a plurality of electron emission devices each including a pair of opposing electrodes. The substrate is prepared using an intaglio plate having recessed portions corresponding to a pattern of the electrodes, the depth of the recessed portions being in the range from 4 &mgr;m to 15 &mgr;m, filling the recessed portions with ink, pressing a blanket against the intaglio plate so that the ink is transferred from the inside of the recessed portions onto the blanket, and bringing the blanket into contact with the substrate so that the ink is transferred from the blanket onto the substrate thereby forming the electrode pattern.

A card connector includes a connector housing formed by supporting a basal end of a cover on a basal end of a base through a pin such that the cover can open and close with respect to the base. A card insertion port is formed in a free end of the cover, and an IC card can be inserted into the cover through the card insertion port. Then, the cover holding the IC card can be closed with respect to the base, so that external terminals of the IC cards are brought into contact, under pressure, with contacts formed on the base. The card connector also includes a lock bar extending in parallel to the card receiving port and resiliently held, in a locking direction, on the other end portion of the base such that the lock bar can be rotated in a locking direction and in an unlocking direction, the lock bar being brought into locking and unlocking relation with the free end of the cover to realize a locking and an unlocking state.
摘要:
A voltage generator for generating an output voltage at an output terminal thereof which includes a first transistor of a first channel conductivity type having a first end connected to the output terminal and a feedback regulator connected to the output terminal. A switch is connected between a voltage node and a second end of the first transistor, the switch receiving a switching signal.
摘要:
A method for purifying an amino acid selected from the group consisting of valine, leucine and isoleucine easily in high yield and with high purity using an inexpensive precipitant, comprising allowing p-ethylbenzenesulfonic acid or its water-soluble salt to act on an aqueous solution containing an amino acid to form crystals of the amino acid p-ethylbenzenesulfonate and then separating and decomposing the crystals to purify and obtain the amino acid. The p-ethylbenzenesulfonic acid may be used as the free acid, an alkali metal salt and an ammonium salt.
