Title: Flexible underpressure adjusting seat for ink cartridge
Inventor: CHOU CHING-YU
IPC: B41J2/175
Filed: 2001-07-27
Granted: 2003-03-21
Abstract: The present invention provides an under-pressure adjusting seat capable of preventing the interference or influence of the magnetic field. According to the present invention, the ink cartridge is configured with a venting hole linked with the atmosphere, and connected with a flexible seat. The seat is configured with air-tight components to push against the air-tight component to tightly seal the venting hole by the spring force provided by the flexible seat, so that the external air can not get into the ink cartridge. In the operation, when the ink level in the ink cartridge is lowered due to consumption in the printing operation, because the valve is closed to prevent entrance of the outer air, the under-pressure in the cartridge is continuously increased. When the under-pressure approaches to a configured critical value, the force applied on the air-tight component by the flexible seat is just balanced with the force applied by the atmospheric pressure on the flexible seat. Thus, when the under-pressure keeps increasing, the air-tight component will be slightly pushed away by the atmospheric pressure to flow a slight amount of air into the cartridge, and the under-pressure is recovered to the operable range. At that time, because the pressure difference between the inner and outer cartridge is reduced, the flexible seat can push against the air-tight component again, so as to prevent the air from entering through the venting hole of the ink cartridge, and maintain the under-pressure status inside the cartridge.

Title: Pressure reducing valve
Inventor: HORI HIDEJI
IPC: F16K31/44
Filed: 2001-10-29
Granted: 2003-07-21
Abstract: The subject of this invention is to provide a pressure reducing valve not having the problem of reducing a controlled flow rate with a mechanism to roughly offset bi-directional thrusts each other by generating the opposite directional thrust matching to a secondary pressure in order not to obstruct a lever operation when the operating force of the lever is increased by unidirectional thrust generated by the secondary pressure, in comparison with a conventional pressure reducing valve without the mechanism. The solution of this invention is as follows. A pressure reducing valve has a spool, and the spool receives against the secondary pressure while receiving a thrust from the outside via a piston in the direction of resisting the secondary pressure, and moves in a hole in the valve seat. The secondary pressure, corresponding to the moving amount of the spool, is reduced from a primary pressure, and the output thereof can be adjusted. Furthermore, the aforementioned secondary pressures are received partially by spool and piston via a channel in the valve seat to communicate from the secondary pressure side to the piston.

Abstract: Disclosed is a highly accurate oriental language, such as Chinese, input method and device for a small-sized electronic device with few keypads and/or a small amount of memory, such as a PDA, mobile phone, electronic dictionary, and electronic watch, in an adverse environment. It is achieved by uttering each multi-syllable Chinese character into isolated tonal syllables in which the vowels and consonants of the isolated tonal syllables are separated by automatic speech recognition while pressing one of the specifically designed keypads for example, a keystroke that contains a first phoneme of a syllable (consonant or vowel) to further resolve the ambiguity derived from the acoustic realization of pin-yin pronunciations (sub-word units), for example, consonant, in the adverse environment. Pressing the second or third pin-yin pronunciation of a syllable is necessary if ambiguity still exists. The keypad design is in a data-driven manner that the ratio of similarity of phonemes within each keypad is minimized and the ratio of similarity of pin-yin pronunciations between keys is maximized.

Title: Video image compressing/decompressing method
Inventor: WEI CHENG-HUNG
IPC: H04N7/26
Filed: 2002-12-04
Granted: 2004-06-21
Abstract: The present invention provides a video image compressing/decompressing method, which is an image compressing method established by utilizing the tolerable error range for the colors viewed by human eyes. A difference Delta between the value (a) of a first pixel and the value (b) of a second pixel is fallen in one of multiple levels for being used as a base to encode. The actual encoding performs Huffman coding based on multiple levels, instead of the Delta value itself. That is, the values (b) of all Delta in a certain level are encoded as the same code. In decompressing, the encoded value is used to reversely check the level where the difference Delta falls for being calculated as a (b') value to substitute the (b) value based on a certain reference value and the (a) value of the level.
