摘要： An ink jet head has an ink head main body that is constituted of a substrate, spacers that are formed on one side of the substrate, and a roof plate that is joined to the substrate through the spacers. One or more ink passages are independently formed between the substrate and the roof plate. Rows of piezoelectric devices, each of which is made of a plurality of piezoelectric devices aligned along each ink passage, are formed through the respective ink passages. Ac voltages whose phases are different from each other by 90 degrees are applied to the respective piezoelectric devices. Progressive waves, which are excited by the rows of piezoelectric devices, allow ink to move through the ink passage and to be sprayed.

摘要： A method of and a photomask for manufacturing an optical memory element. The manufacturing method includes the steps of: subjecting a positive type photoresist coated on a glass substrate to exposure by using the photomask capable of irradiating light onto a portion of the photoresist other than the remaining portion for forming pits of the glass substrate such that the portion of the photoresist is solubilized against developing solution; developing the photoresist by using the developing solution so as to remove the portion of the photoresist; and etching the glass substrate so as to directly form, as convex portions, the pits on a surface of the glass substrate.

摘要： A first laser beam is emitted from a first laser oscillator in a pulsed manner at a high repetition frequency, and converged onto a substrate by a first intermediate optical system 2 so as to form a slit-like first beam spot. A second laser beam is emitted from a second laser beam oscillator in a pulsed manner to rise precedent to and fall subsequent to the first laser beam, and converged onto the substrate by a second intermediate optical system so as to form a second beam spot similar in configuration to the first beam spot and to contain the first beam spot. Crystallization of a semiconductor thin film on the substrate is carried out while the substrate or the first, second beam spots are moved. Thereby, the whole semiconductor thin film is formed into a crystal surface that has grown in one direction and free from ridges. Thus, the semiconductor thin film has an extremely flat surface, extremely few defects, large crystal grains and high throughput.
