Title: Ink jet recording method
Inventor: MORIGUCHI HARUHIKO
IPC: B41J2/055
Filed: 1990-07-05
Abstract: PURPOSE:To obtain a longer life of an ink jet recording head and to perform a high-reliable recording by a method wherein a voltage pulse of approximately the same level as an electric potential of a delivery control element at the time of conduction is applied to ink in synchronism with a conduction pulse. CONSTITUTION:When ink is delivered from an ink jet recording head 2, a voltage pulse of approximately the same level as an electric potential of a delivery control element 12 at the time of conduction disposed within the ink jet recording head 2 is applied to ink in the ink jet recording head 2 in synchronism with a conduction pulse. In this manner, the ink is kept at approximately the same electric potential as the delivery control element 12, whereby an electric current flowing between the ink and the delivery control element 12 is eliminated or adequately reduced. In this manner, the life of the ink jet recording head 2 can be extended, and recording can be performed with a high reliability.

Abstract: PURPOSE:To prevent irregular flickering of photooutput while making anode oscillation to be stably generated by specifying thermal conductivity, at a room temperature, of an internal lead-in wire for supporting a filament coil to 0.3-0.9 cal.sec<-1>.deg<-1>. CONSTITUTION:Thermal conductivity, at a room temperature, of an internal lead-in wire 4 for supporting a filament coil 5 is to be within the range of 0.3-0.9cal.cm<-1>.sec<-1>.deg<-1>. When thermal conductivity, at a room temperature, of the internal lead-in wire 4 becomes less than 0.3cal.cm<-1>.sec<-1>.deg<-1>, anode oscillation becomes hard to be stably generated while generating irregular flickering. Further, when the thermal conductivity, at a room temperature, of the internal lead-in wire 4 exceeds 0.9cal.cm<-1>.sec<-1>.deg<-1>, mechanical strength weakens thus increasing scattering in an electrode form, resulting in undesirable state of lamp quality. In this way, the anode oscillation stably exists in the lamp having the thermal conductivity 0.3-0.9cal.cm<-1>.sec<-1>.deg<-1> while generating no irregular flickering.

Title: Delay line and ultrasonic diagnostic device using the same
Inventor: KONDO TOSHIRO
IPC: H03H7/30
Filed: 1990-07-06
Abstract: PURPOSE:To continuously change delay time by a control voltage by serially connecting plural unit parts composed of capacitors and inductors connected in reverse-parallel with variable capacity diodes whose electrostatic capacity is changed according to the size of an inverse voltage. CONSTITUTION:The input of an ultrasonic signal is supplied through an electronic control variable resistor 10, capacitor C and terminal resistor R to a delay line 6. The delay line 6 is formed by serially connecting unit parts 7 formed by capacitors connecting inverse-parallel with two inductors L and variable capacity diodes Vc1 and Vc2. The fluctuation of capacity is canceled by impressing a control signal Ec1 and an inverted 14 Ec2 from a control terminal 8a to the respective Vc1 and Vc2. By changing the value of the signal Ec1, the delay time is controlled. The outputs of plural probes out of the figure are inputted to plural delay lines having various delay time, and those outputs are added and displayed. Thus, dynamic focus can be obtained while suppressing transmission distortion and continuously changing the convergent point of an ultrasonic beam.
