Inventor: SHIODA TOYOJI
IPC: B41J2/045
Filed: 1984-07-04
Abstract: PURPOSE:To protect the state of equilibrium of ink in an ink jet head from the impulsive pressure variation of ink by communicating the head with the outside by an ink fountain and forming an ink flow path having a sectional area larger than that of an injection channel system. CONSTITUTION:An ink flow path 301 is shaped up to a nozzle hole 101 section from the upper section of an ink fountain 105, and the sectional areas of the ink flow path 301 and an outlet 302 are each made larger than those of pressure chambers 104 and nozzle holes 101.

Title: Apparatus for measuring thickness of solidified cast piece
Inventor: NARITA YUTAKA
IPC: G01N29/04
Filed: 1983-07-29
Abstract: PURPOSE:To provide an accurate apparatus which is operated safely in a severe environment, by attaching an electromagnetic ultrasonic wave generator and an electromagnetic ultrasonic wave receiver to a detector for the total thickness of a cast piece. CONSTITUTION:A pulse signal is conducted through a generating coil 3 by a pulse generator 8, and a pulse magnetic field as shown by an arrow 17 is generated. An electromotive force is induced on the surface of a cast piece 7 and an eddy current 18 is generated. A pulse electromagnetic force is generated by the mutual action with the pulse magnetic fields of the arrow 17. Ultrasonic wave vibration is generated on the surface of a cast piece 7 by said force. The electromagnetic ultrasonic wave generated on the surface of the cast piece 7 advances in the direction of an arrow 19 in the cast piece 7. When the wave reaches the other surface, vibration is generated on the surface of the cast piece 7. An electromotive force is generated on the surface of the cast piece 7 by the mutual action of the vibration and the magnetic field, which is generated by an exciting coil 5 excited by an exciting power source 9. Said electromotive force is amplified by an amplifier 10. A part required on the time axis is taken by a gate circuit 11 and sent to a transmitted-time measuring circuit 12. The thickness of the cast piece 7 is measured based on the time difference between the input signal from the gate circuit and the pulse output timing signal.

Abstract: PURPOSE:To enable elimination of interference components, by measuring the measured light and reference light in a photo detector by passing part of the light through measuring cell, temperature compensation cell and filter and the other part of light through interference cell, interference compensation cell and filter. CONSTITUTION:When a sector 9 is at the side of interference cell 8, the light leaving an infrared ray source 1 runs in the route of concave mirror 8, temperature compensation cell 7, measuring cell 2, concave mirror 12, filter 5 and photo detector 11, so that the quantity of light reached Lm is detected. When the sector 9 rotates 180 degrees, the infrared ray runs in the route of mirror 8, aperture 13, interference cell, interference compensation cell 4, mirror 12, filter 6 and detector 11, so that the quantity of light reached Lr is detected. From the difference in the quantity of light reached of detector 10, DELTAL=Lm-Lr, the length of cell 7 and the concentration of sealed gas are adjusted. By adjusting the aperture 13, the term of temperature compensation is made to zero or constant. By passing gas containing interference component but not containing measurement component, the length l of the  cell 4 is adjusted and the interference component is eliminated. Hence, the measurement component concentration Lx may be obtained accurately regardless of fluctuations of interference component concentration.
