Title: Storage device
Inventor: SAKURAI HIROSHI
IPC: G06F12/16
Filed: 1989-04-17
Abstract: PURPOSE:To shorten a data access time and to improve the efficiency of data access by sending data having no error as the checked result of an error checking means. CONSTITUTION:In the case of storing data in a storage means 2, data sent from the external by an access means 7 are simultaneously stored in the 1st and 2nd storage areas 20, 21 of the storage means 2.

Title: Ink jet recording head cartridge and ink jet recording device using the cartridge
Inventor: SUGIMOTO HITOSHI
IPC: B41J2/185
Filed: 1990-04-11
Abstract: PURPOSE:To ensure that an ink feed path and the interior of a recording head are filled with ink without repeated interrupted ink feed even if a compact small-capacity pump is used by providing an area where the liquid resistance of ink increases in the ink feed path of a recording head unit when an ink jet cartridge consisting of an ink feed tank and a head unit formed in one piece is employed. CONSTITUTION:A filter 701 is provided on a part of an ink feed path 5 and the volume of an area between a filter 700 in contact with an absorber 900 and the filter 701 is set to be smaller than the suction capacity of a pump. Consequently, the ink cannot be sucked upto the discharge orifice of a recording head in the first round of suction recovery, and the ink is retained by the filter 701 due to the retaining force of an ink meniscus formed in the mesh part of the filter 701, if the ink is held back by a negative pressure force of the absorber 900. Thus the ink is no longer held back upto the ink tank. Further, the ink is securely sucked as far as the discharge orifice of the recording head due to the second round of a suction pump action and the entire recording head unit is filled with the ink.

Abstract: PURPOSE:To dispense with a masking register by controlling a device so that initial values are set for some N bits, and simultaneously, the inverted value of the bit in a comparison value to which one bit, at least, other than said N bits corresponds is set for said one bit. CONSTITUTION:A decoder 4 sends a set signal to a register 9 corresponding to least significant N bits besides the register corresponding to the instructed N bits. Simultaneously with it, the decoder 4 sends a select signal so that selectors 11,12 and 13 select input data 5. Thus, a set value selecting device 6 selects the value of the input data to be selected by the selector 14, and the output of the selector 14 is inputted to the register 9 through the selector 13 in s counter 1, and the set value is set. Therefore, not only the masking register necessitated in the past comes unnecessary, but the control of mask processing comes unnecessary as well.
