Title: Ink jet recording head and ink jet recorder
Inventor: HIROZAWA TOSHIAKI
IPC: B41J2/05
Filed: 1993-11-17
Abstract: PURPOSE:To eliminate discharge malfunction at the initial of starting recording, and to provide high speed response and discharge stability by providing one or more recesses isolated from a liquid chamber by a flexible member as an air chamber on a wall of the chamber formed of a groove of a second substrate. CONSTITUTION:A recording head is formed with an ink liquid chamber 9 on a second substrate 3, engraved with a recess on a wall of the chamber 9, and adhered with a flexible member 11 to the recess to form an air chamber 10. The member 11 which has ink resistance and a high efficiency of a pressure transmission is selected. Then, force for pressing ink toward the chamber 9 is generated in each channel, and since the chamber 10 of the member 11 exists in the chamber 9, and hence a pressure is absorbed. As a result, a force for pressing ink to an ink supply tube from the channel 12 to the chamber 9 is alleviated or prevented. In this case, a moving force toward the channel 12 is caused by a surface tension of a meniscus to discharge absorbing force by the air of the chamber 10 for the pressure to operate to supplement a pressure for moving ink toward an orifice in a refill.

Abstract: PURPOSE: To attain optional display and well-shaped display by determining an area based upon the display position and size of an already displayed character and specifying the display position of a newly written character based upon a judged result whether a representative point of the newly written character exists in the determined area or not. CONSTITUTION: A coordinate input means 101 inputs a coordinate value, a handwritten character recognizing means 102 recognizes a character and a display position/size determining means 104 determines the display position and size of the character to determine an area based upon the determined result. Then a representative point is determined based upon a set of coordinate values of depression points of a writing means in a newly written character, and when the representative point exists in the area, a display position is determined based upon the display position and size of the already displayed character, and if the representative point does not exist in the area, the display position is determined based upon a set of coordinate values of depression points of the writing means.  When the newly written character is written on a position related to the already written character, both the characters are aligned, and when the character is written on an unrelated position, the character can be independently displayed.

Filed: 1991-11-06
Abstract: PURPOSE:To reduce the overrun of data by comparing the condition of a data buffer in each channel device with a threshold appropriately set up in accordance with the type of an interface and changing the priority order of memory requests. CONSTITUTION:A control circuit 21 sets up a proper threshold in a threshold register 35 in accordance with the using condition of a data buffer 31 in each channel device 30 and the interface type of a corresponding peripheral device 40.

When plural memory requests compete, the circuit 23 commands a request selection replay distributing circuit 22 to receive the memory request of the channel device 30 sending the signal with priority. Consequently the overrun of data can be reduced.
