Filed: 1990-02-07
Abstract: PURPOSE:To ensure high print quality by inclining the bottom face of a recess in the front face of a nozzle in an ink jet recording head, by some angle, against the front face of nozzle thereby bringing an absorbing member into positive contact with the recess and removing ink therefrom. CONSTITUTION:An ink jet recording head 1 is disposed so that the ink is jetted in lower leftward direction. When printing operation is not carried out, a cap 6 covers the front face 4 of nozzle in the ink jet recording head 1, as shown on the figure, and an absorbing member 7 is brought into contact with a recess 5 in an ink jet substrate thus absorbing the ink. Since the absorbing member 7 in the cap 6 is brought into positive contact with the recess 5 and removes the ink, when the bottom face of the recess 5 in the nozzle front face 4 is inclined against the nozzle front face 4, ink layer in the nozzle front face 4 can be shaped resulting in a high print quality.

IPC: G01N21/15
Filed: 1980-03-05
Abstract: PURPOSE:To eliminate a fouling on the exposed surface in an atmosphere of a light-receiving device and perform accurate light energy by logarithmically converting and multiplying by a constant an output from the first and second light-receiving elements and performing a mutual addition or a mutual subtraction and a reciprocal logarithmical convertion of the product or the remainder. CONSTITUTION:An output from each light-receiving element S1, S2 is conducted to logarithmical conversion circuits 1, 2 respectively to be logarithmically converted with the assistance of a light- receiving element S1 which receives a penetrating light at a position where the light penetrating through a half mirror HM with a light-receiving plane exposed to an atmosphere, is shielded against an atmosphere and a light-receiving element S2 which receives a reflective light at a position where the said light is exposed to an atmosphere. Following this process, output voltage from the reciprocal logarithmic circuits V1, V2 are multiplied 3/2, 1/2 by means of arithmetic circuit 3, 4 respectively and then are added by means of an addition circuit 5. An output voltage V3 from the addition circuit 5 is converted to a reciprocal logarithm by means of a reciprocal logarithmical circuit 6. In addition, an output current I4 from the reciprocal logarithmical circuit is converted to a voltage V4 by means of an electric current-voltage conversion circuit 7. Then an output voltage 1/4 proportional to an incident light energy L0 is obtained regardless of a fouling on the light- receiving plane.
