Patent JP-S58193158-A (JP)
Title: Ink supplier
Inventor: HARA TAKAFUMI
IPC: B41J2/175
Filed: 1982-05-06
Abstract: PURPOSE:To prevent the leakage of ink from an air hole and clogging an air hole by such as arrangement wherein the air hole is drilled in the upper wall of an ink tank and protruded walls are provided inside the ink tank so that their one ends are faced to the upper wall of the ink tank. CONSTITUTION:Ink 150 flows into an ink chamber 115 through an ink flowing passage from an ink tank 16. At the time of printing, signals are given to a piezoelectric element 116 and a nozzle slit unit 113 spouts ink particles in response to the vibration of the piezoelectric element 116 and performs printing. Since a carriage 12 causes mechanical vibration as it slidably moves on slide bars 14a, 14b, the surface of ink liquid oscillates. The width of oscillation of ink wave is considerably reduced by vicous friction generated between protruded walls a1, a2, a3 and ink 150. Therefore, the surface of oscillating wave doesn't reach the height of an air hole 21, even if vibration is large, and ink doesn't leak from the air hole 21, or ink doesn't clog the hole 21.

Title: Supercharged pressure display device for internal combustion engine provided with supercharger
Inventor: YAMAGATA TETSUO
IPC: G01L23/24
Filed: 1981-05-19
Abstract: PURPOSE: To make it possible to display two kinds of pressures by a single display device by a method wherein in case the condition of supercharge pressure is displayed to the operator of the engine, a boost pressure is displayed in the idle operation of the engine while the supercharge pressure is displayed in a high load operation zone of the engine.  
     CONSTITUTION: A supercharge pressure senser 5 and a boost pressure senser 6 are provided on the upstream and the downstream sides of a throttle valve, respectively, in an air intake passage of the titled engine and the output of the senser 6 is applied on the positive terminal of a differential amplifier of a comprison circuit A and on the positive terminal of an amplifier 11 of an amplifying circuit C. In this case, when the output of the senser 6 is smaller than a predetermined voltage, the output of the differential amplifier 8 goes to L-level and a transistor Tr12 and a transistor Tr13 of a  selective circuit B goes OFF and ON respectively. Consequently, the output of the  senser 5 is grounded while that of the senser 6 is amplified by the amplifier 11 so as  to be displayed on a display device 7. On the other hand, when the output of the  senser 6 is larger than the predetermined voltage, the transistor Tr12 goes ON and the  transistor Tr13 goes OFF so that the output of the senser 5 is displayed on the display  device 7.

Title: Delay distortion equalizer
Inventor: OKADA KENJI
IPC: H03H15/00
Filed: 1978-06-24
Abstract: PURPOSE:To reduce the circuit in scale and also to simplify the adjustments by utilizing that a pulse waveform with delay distortion has waveform distortion opposite in polarity and equal in amplitude before and after a main pulse. CONSTITUTION:Around time T, input signal A given waveform distortion owing to delay distortion is supplied to input terminal 11. This signal A is branched to two by delay circuit 12; one becomes waveform C by passing through circuit 12 and the other has its amplitude and polairty controlled by weighting circuit 14 and then becomes waveform B with two separate pulses of the identical and opposite polairites by waveform equalizer circuit 18. Branched waveform outputs B and C are added together by adder circuit 16, so that waveform D with the delay distortion removed will appear at terminal 17. Consequently, a delay equalizer which usually required three taps can be realized by two taps and, therefore, only one weighting circuit is needed, so that amplitude adjustments taps will be simplified.
