Title: Method for driving ink jet head
Inventor: NAKANO TOMOAKI
IPC: B41J2/205
Filed: 1994-08-22
Abstract: PURPOSE: To establish a maximum driving frequency in the frequency components of the driving waveform in such a manner as to avoid coincidence with the natural frequency of an ink jet head, damp the residual pressure wave in liquid chambers, and improve the frequency characteristics of ink droplet injection speed and volume. CONSTITUTION: Pulse voltage is applied to the piezoelectric elements 7a and 7b of a head as driving signal according to printing data. The m-th (m is natural number 1, 2...) high frequency components are included in the pulse waveform of the pulse voltage. The maximum driving frequency fmax of the driving signal for driving the head is established and the head is driven in the driving frequency fn divided by n (n is natural number 1, 2...) according to the printing data.  Therefore, when the maximum driving frequency of the head is fmax and (m) and (n) are natural number, when the maximum driving frequency fmax is established in such a manner as to avoid coincidence of the frequency component (m/n) fmax in the driving waveform with the natural frequency of the head, the residual pressure wave in liquid chambers 4a and 4b can be damped and the ink droplet injection speed and volume will not vary with the driving frequency.

Title: Liquid-charged bush
Inventor: SHIMOKAWA TOSHINORI
IPC: F16F13/14
Filed: 1995-07-11
Abstract: PROBLEM TO BE SOLVED: To display desired performance with a simple structure and reduce its production cost. SOLUTION: When an inputted vibration is the displacement of a low frequency big amplitude, in the half period of the displacement, the charging liquid in a first liquid room 5 compressed by the deformation of an elastic body 3 flows toward the second liquid room 6 with a volume varied by a diaphragm 4 through a shock orifice 7 whose flow passage is long and narrow and further in the next half period, the charging liquid flows back through the shock orifice 7 from a compressed state toward the first liquid room 5 in a restoration process and high attenuation by a flow resistance is generated in this process.  When the inputted vibration is a vibration with a continuous small amplitude in a high frequency zone, the enclosed liquid absorbs the pressure change of the first liquid room 5 following the vibration input is absorbed and a vibration transmission is broken off by that the charging liquid is moved repeatedly little by little in the idle orifice 8 with a small flow resistance while following the repeated displacement by the small amplitude of a thin film 9.

Title: Piezoelectric vibrator
Inventor: KANEKO TAKAYUKI
IPC: G01P15/09
Filed: 1997-07-23
Abstract: PROBLEM TO BE SOLVED: To provide a piezoelectric vibrator wherein couplers constituting connection sections is hardly deformed with ease even if a shock is applied from the longitudinal direction of the vibrator.

Title: Eddy current flaw detecting device
Inventor: HATAMOTO KAZUO
IPC: G01N27/90
Filed: 1982-11-09
Abstract: PURPOSE:To ensure the output of a flaw signal and to shorten the dead band at the tip without erasing the flaw signal of a relatively low frequency, by determining time constant at every time when the output of a temporary phase comparing means is arbitrarily set, readily changing the time contant based on the way of obtaining the added time, controlling the phase of a sine wave in a broad range, and changing the time constant even though the frequency of the flaw signal is changed. CONSTITUTION:When the end of a material passes a detecting coil, the end of the material is detected, and a switch SW1 is closed for a specified time. A relatively large unbalanced output S5 becomes a pulse S6 and is directly imparted to an input terminal IN2 of a gain and delay quantity determining circuit 2. Based on the input, the gain and delay quantity determining circuit 2 imparts specified phase control data to a frequency dividing circuit 1. Meanwhile the pulse S6 is imparted to an NOR circuit 6, too. An ''L'' is inputted to a load terminal L of the frequency dividing circuit 1. Therefore, the phase control data is loaded at the rise up of the clock pulse. The phase of a pulse S1, which is the output of the frequency divider 1, is quickly controlled. Therefore, the phase of a sine wave S3 can be made to follow the phase of the unbalanced output S5, and the dead band at the tip can be made short.

Filed: 1984-09-21
Abstract: PURPOSE:To prevent malfunctions of a central processor by providing a detecting means for application state of power supply and a means which disables the switch of an electromagnetic relay contact to be carried out by a changeover switch with the detection signal given from said detecting means. CONSTITUTION:The level of a signal 22 is set at low and high levels when a power supply is applied to a device 5 and not respectively.
