Title: Liquid drop injector
Inventor: MATSUDA YASUMASA
IPC: B41J2/205
Filed: 1980-03-10
Abstract: PURPOSE: To provide a subject device, for use with an ink jet printer, which is provided with a liquid diameter correcting means for adjusting a size of an electric signal to be applied to an electromechanical transducing part, and can prevent the liquid diameter from changing after quiescence of said electric signal.  
     CONSTITUTION: Liquid from a liquid feed tank is caused to operate an electromechanical transducing part 18 according to an electric signal applied to cause a change in volume, and printing is conducted on a recording sheet by jetting liquid drops through a liquid drop jet head 1. In case a quiescent period T being wider than a given width is set at a pattern of an electric signal applied to the electromechanical transducing part and at least 3 consecutive electric signals are then set, a liquid drop diameter correction means, for example, a variable amplifier 27, which increases a size or width of the second electric signal out of the 3 consecutive electric signals, is mounted to correct a liquid diameter rs. The first liquid drop diameter rl tends to be too large and the second one tends to become too samll: such tendency is corrected.

Title: Seismoscopic device
Inventor: FUJII MANABU
IPC: G01H9/00
Filed: 1981-03-02
Abstract: PURPOSE:To perform seismoscopic operation having no effect of electric noise and less malfunctions by detecting the behavior of a seismoscope optically by using optical fibers. CONSTITUTION:While a steel ball 1 is held supported in a holder 4a, the light emitted from a light source 13 conducted by an optical fiber 19a and is emitted into a recess 41. This light is reflected on the surface of the ball 1, is made incident to the fiber 19a, is conducted into an optical fiber 19b and is made incident to a photodetector 4. There, it is converted to an electric signal which is inputted to a microcomputer 12. When the ball 1 drops onto a receiving tray 2 on account of oscillations, the light emitted into the recess 41 through the fiber 19a advances straightforward as it is and is not made incident to the fiber 19b; therefore the output signal of the photodetectr 14 annihilates. The microcomputer 12 discriminates whether a semismoscope 10 has operated or not from the presence or absence of the output signal of the photodetector 14.
