Title: Residual quantity of ink detector for on-demand ink jet printer head
Inventor: YAMAZAKI HIROSHI
IPC: B41J2/175
Filed: 1987-02-03
Abstract: PURPOSE:To obtain a residual quantity of ink detector having high detection accuracy, by converting the displacement of an ink bag film caused through consumption of ink in perpendicular direction. CONSTITUTION:Under ink-Full condition, a thin flexible board 25 retracts into a V-groove 23 and a color indicating section 26 located at the tip section thereof for recognizing exhaustion of ink is contained in a guide 27. When an ink bag film 20 shrinks due to consumption of ink, a guide ribbon 24 is pulled gradually. Under ink-Empty condition, the guide ribbon folded in the groove 23 is exposed to the outside of the V-groove; thereby, the thin flexible board 25 secured in the central portion thereof is lifted so as to lift the color indicating section 26 for recognizing exhaustion of ink along the guide 27, thus projecting the color indicating section 26 to the outside of an ink cartridge case 18.

IPC: B41J2/335
Filed: 1989-02-02
Abstract: PURPOSE:To lessen a difference in level of a wear resistant layer from another surface part without decreasing pulse resistant strength of a heating resistor by a method wherein the heating resistor is buried in a surface of an insulating substrate. CONSTITUTION:After forming an electrode forming layer on a surface of a heat accumulating layer 2b, a common electrode 3 and an individual electrode 4 are formed by photolithoetching. Then, a heating resistor 5 connecting between both electrodes 3, 4 is formed by a lift-off process. Herein, since the heat accumulating layer 2b is softened in burning a non sintered resistor 5a, the non sintered resistor 5a is burnt while it is being sunk into the heat accumulating layer 2b by its dead load. Therefore, the formed heating resistor 5 together with both electrode top connection parts 3b1, 4a are buried in the surface of the heat accumulating layer 2b. Then, surfaces of both electrodes 3, 4, the heating resistor 5, etc. are covered by a glazed wear resistant layer 6. Thus, a surface 6a of a part covering the heating resistor 5 of the wear resistant layer 6 is projected from another surface part 6b, and a low stage part 6c is formed in a boundary part thereof.

Title: Mechanical translation device
Inventor: SAKAI MINORU
IPC: G06F17/28
Filed: 1989-02-02
Abstract: PURPOSE:To minimize the wrong analyses caused by the corrections of dictionaries by combining the grammar dictionaries and the word dictionaries and analyzing the original sentences while switching these dictionaries in sequence when the analyses fail. CONSTITUTION:Plural grammar dictionaries 161 - 16m and word dictionaries 151 - 15m are prepared for analysis of original sentences. The original sentences inputted from an input part 13 are sent one by one to a translation part 12. These inputted sentences are analyzed with use of a basic dictionary after both dictionaries 16 and 15 are combined. If the analysis fails, these dictionaries 15 and 16 are switched in sequence to carry out the second analysis. Thus the special information is available only when the analysis fails and therefore the wrong analyses due to the corrections of dictionaries can be decreased. Then the analyzing factor is improved.

Title: Output interface circuit
Inventor: KAMEYAMA ATSUSHI
IPC: H03K5/02
Filed: 1989-02-03
Abstract: PURPOSE:To stably perform logic level conversion by attaching a level compensation circuit to offset the influence on an output voltage by the fluctuation of a threshold value. CONSTITUTION:The level compensation circuit is provided with an inverter 6 in which a fifth FET O5 is used as a driver, a feedback circuit 7 provided between the input and output terminals of the inverter 6, and a sixth FET Q6 provided between the positive polarity side power source terminal (ground, in figure) of a differential amplifier circuit 2 and load resistors R2 and R3 and is controlled by the output of the inverter 6. The output voltage of the inverter 6 fluctuates almost in proportion to the fluctuation of the threshold value of the FET Q5. The fluctuation of the output of the inverter 6 is transmitted as it is from the gate of the FET Q6 to the source. The source potential of the FET Q6 goes to the output potential of the differential amplifier circuit 2 as it is, and it is transmitted to the gate of a source follower FET Q4. Thus, the fluctuation of the potential transmitted from the inverter 6 to the FET Q4 just offsets that of the output potential due to the fluctuation of the threshold value of the FET Q4.
