Title: Ink jet printer head
Inventor: NAKAYAMA TETSUO
IPC: B41J2/06
Filed: 1984-05-16
Abstract: PURPOSE:To obtain good printing by concentrating an electric field only to one place of ink, by making the thickness of the projecton, where the leading end of a recording electrode is positioned and ink is turned around, thinner toward the leading end thereof. CONSTITUTION:Large number of projection 16, each of which becomes thinner in its thickness toward the leading end thereof and received cutting processing in its underside are provided to a PC plate 2 and the leading ends of recording electrodes 1 are arranged to said projections 16, the ink film 18 of the ink 4 in an ink jet orifice 6 is turned around each projection 16 to wet the leading end of each recording electrode 1 but formed in a miniscus state along the shape of the projection in the vicinity of the leading end of each projection. When a recording signal is applied to the recording electrode 1, the concn. of an electric field is generated only at one place because the ink film 18 is formed in the meniscus state. Therefore, the ink 4 is easily flied from each projection 16 and always flown in the same state and adhered to recording paper to form a uniform dot.

Title: Variable gain amplifier
Inventor: OKAMOTO CHIKAYUKI
IPC: H03G3/10
Filed: 1981-06-26
Abstract: PURPOSE:To vary a gain over a wide range from negative to positive by connecting a constant voltage source to one input terminal of a differential amplifier, and also providing a current absorbing ciruit, varying in a value with an  input signal, at the other input terminal. CONSTITUTION:The signal V28 from an input signal voltage source 28 is applied to a resistance 27 with a resistance value R27 to flow a current V28/R27 in the resistance 27. Then, a current gm(V22-V21) flows through a resistance 26 by the voltages V21 and V22 at the input terminals 21 and 22 of a differential amplifier 20, and the mutual conductance gm of the amplifier 20. The current flowing from a constant voltage source 23 through a resistance 24 corresponds to the difference in current value between the resistance and a current absorbing circuit 32. From the current flowing through the resistance 24, the voltage V21 at the input terminal of the differential amplifier is found. Similarly, the voltage V22 at the input terminal 22 is also found. The output voltage obtained from the relation between both the input voltages has both positive and negative values in accordance with the value of the gm.

Title: Lead frame
Inventor: URASAKI YOSHIO
IPC: H01L23/50
Filed: 1988-04-20
Abstract: PURPOSE:To reduce the warpage of a lead frame, and to solve trouble in after- processes using a pilot hole by forming a gap between the nose of an outer lead on one side and a tie bar on the other side. CONSTITUTION:A gap 6 is shaped among the noses of outer leads 3 in a section, in which one molding section 2 is formed, and tie bars 5 on the section side in which an adjacent molding section 2 is shaped.
