Title: Junction type fet
Inventor: KASAHARA KENICHI
IPC: H01L29/808
Filed: 1984-06-26
Abstract: PURPOSE:To obtain the titled device capable of easily obtaining characteristics as designed by a method whrein a P-N junction is formed by a gate layer and a current channel layer. CONSTITUTION:An N-in0.53Ga0.47As layer 22 serving as the N type current channel layer is epitaxially grown on a semi-insulation InP substrate 21. Next, an Si3N4 film 23 is deposited on the layer 22; thereafter, the part serving as the gate region is removed by a width of 2mum, where a P-InP layer 24 is grown, and then an epitaxial layer is selectively formed only in the aperture instead of growth on the Si3N4 film 23. When Au/AuZn is evaporated over the entire surface and patterned and cleaned with supersonic waves after alloying, a gate electrode 25 is left only on the P-InP layer 24. The Si3N4 film 23 is removed in the parts of a source electrode 27 and a drain electrode 28, where Au/AuGe-Ni is evaporated and patterned, thereby forming the source and drain electrodes.

Title: Ink jet head and its manufacture
Inventor: MORITA RYUSUKE
IPC: B41J2/16
Filed: 1992-05-25
Abstract: PURPOSE:To enable good printing quality to be maintained by stabilizing a discharge direction of an ink drop by a method wherein an inner peripheral surface on at least a nozzle side of an ink passage of which a tip is made to be a nozzle, is formed only with a curved surface in an inside. CONSTITUTION:After dissolving and diluting a fluid coating agent in solvent according to a thickness of a film 12 to be formed in an ink passage 4, an inside of the ink passage 4 of a glass plate 2 is filled therewith by a capillary phenomenon. Then, the glass made film 12 is formed by carrying out baking. Since an inner peripheral surface of the film 12 is composed of only a curved surface without any edge part, it will be not feared that a discharge direction of an ink drop from a nozzle 5 is in a direction different from a specific direction by the capillary phenomenon. Further, since the film 12 is at most 20 deg. in contact angle and hydro-phylic, fluidity of the ink in the ink passage 4 is good and there is no possibility of embracing a bubble in the passage 4. Therefore, the ink drop can be stably discharged from the nozzle 5.

SOLUTION: A cell making device 1 makes an ATM cell from an input data stream of multiplexed data for plural calls for retaining in cell FIFO 2 corresponding to the call. A cycle counter 4 generates numerical values from 0 to 2<n> -1 in matching with the output timing of a cell in order. An output selector 6 compares the numerical value generated by the counter 4 with the value of an index stored by an index storing device 5, and when the values are coincident with each other, the identifier of a call corresponding to the value is transmitted to a multiplexer 3. The multiplexer 3 fetches a cell from a cell FIFO 2 which corresponds to the identifier, transmitted from the device 6 for outputting to an output cell stream transmission line 8.
