Title: Tomograph using analogue picture memory
Inventor: GOTOU TATSUO
IPC: G01N23/04
Filed: 1978-04-03
Abstract: PURPOSE:To make it possible to obtain sectional pictures in a high speed and apply tomograph to the industry measurement field by using an analogue memory as the picture meory. CONSTITUTION:An object which has a uniform transmittivity for X rays and has one position difficult to transmit X rays through is scanned by narrow beam-shaped X rays from an X-ray source, and X rays are received a detector to obtain waveform p1. Next, the position of the X-ray source and the detector is changed to obtain waveforms p2 and p3. Sectional image A' which corresponds to the position difficult to transmit X rays through is obtained while scanning picture memory 5 correspondingly to the scanning results above. Here, a scan converter is used as an analogue picture memory which can overwrite data onto picture memory 5. In respect to the scan converter, influences caused by accessing the memory face by beam can be eliminated if a proper potential is given to the secondary electron control grid to balance the charge of incident electrons and the charge of the secondary electrons. Then, read operation is performed by detecting emitted secondary electrons, and write operation is performed by changing the potential of the control grid.

IPC: B41J2/055
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To provide a recording head capable of recording a high resolution image by ejecting small ink drops without using a nozzle. SOLUTION: When an input signal from a signal generating means 32 is inputted to a vibration generating means 24 in accordance with an image signal, a piezoelectric element 26 is vibrated and an electrode section 28A is excited, then an elastic section 28B of an elastic electrode 28 is subjected to bending vibration. As a result, a capillary wave is generated at a portion in the vicinity of a tip section 28C of the elastic section 28B, then small ink drops are continuously ejected one by one. As the elastic electrode 28 is equipped with the electrode section 28A as an electrode and the elastic section 28B as an elastic member, it is possible to select one from various kinds of materials as the elastic electrode 28 and to process it to be in an optimum shape or thickness.  As another material such as an adhesive is not provided between the electrode section 28A and elastic section 28B, the vibration of the electrode section 28A is not attenuated to be directly transmitted to the elastic section 28B.
