Title: Recording head
Inventor: HIRAGATA SUSUMU
IPC: B41J2/045
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To provide a recording head which can record a high resolution image while reducing the size. SOLUTION: This recording head 10 has a recess, i.e., an ink supply part 14, holding a specified quantity of ink 18 which spreads close to the forward end of an elastic member 26 through surface tension. A signal being delivered from a signal generating means 24 to an oscillation generating means 22 causes bending oscillation of the elastic member 26 and an ink droplet 28 flies from capillary wave generated near the forward end to record a dot on a recording sheet 30. Since no nozzle is employed, a dot can be recorded without causing any clogging of ink even when an image is recorded at a high resolution. When an image is not recorded, the ink droplet 28 hits a collecting face 40 and it can be reused for recording an image. Since flying direction of the ink droplet 28 is altered without requiring any special unit, the recording head 10 can be reduced in size.

Title: Synchronizing separator
Inventor: SHINPO HIROYASU
IPC: H04N5/05
Filed: 1983-02-09
Abstract: PURPOSE:To attain stable synchronous separating action by providing a circuit detecting the presence of a signal in vertical synchronism separation and switching a clamp level of a synchronism separation circuit by the said circuit so as to change over the state into the soft clamp state when lots of ghost signals exist. CONSTITUTION:A video detecting signal at an input terminal D is applied to vertical synchronizing separation circuits 5, 6. The separation circuit 5 has softer clamp constant than that of the separation circuit 6. Thus, if an input signal superposed with a negative ghost signal is inputted, the circuit 6 does not separate a vertical synchronizing signal earlier. The output from the circuit 6 is connected to a vertical synchronism detecting circuit 7, where the presence of the vertical synchronizing signal is detected. The detected output of the detecting circuit 7 is connected to a clamp constant switching circuit 8, and if no vertical synchronizing signal is detected by the circuit 8, the clamp level is changed over so that the clamp circuit of the separation circuit 5 performs softer clamp operation.
