Filed: 1992-12-26
Abstract: PURPOSE:To lower the filtration resistance and enable mass production of filter bodies economically by making innumerable particles for filtration adhere to each skeleton of a skeleton carrier with three dimensional mesh structure having a high ratio of void spaces to hold them in the carrier without pressing them.

To manufacture the filter body while vibration being applied to them, innumerable particles are supplied to a skeleton carrier 2 with three dimensional mesh structure having a high void spacers' occupying ratio to fill the void spaces 3 with them and thus the particles adhere to the skeleton and are held on them. Consequently, not like a conventional one, hot-press and dies are not needed and filter bodies are manufactured economically by mass production.

Title: Fet circuit
Inventor: BITO YASUNORI
IPC: H01L29/80
Filed: 1998-12-18
Abstract: PROBLEM TO BE SOLVED: To have a high-efficiency operation with a small by making the total gate width of a plurality of single gate FETs larger than that of a plurality of dual gate FETs. SOLUTION: The total gate width of a plurality of dual gate FETs is made larger than that of a plurality of single gate FETs. For example, the ratio of the gate width between a dual gate FET and a single gate FET is set to 10:1. With small output, such a gate bias as to allow a channel to be closed due to pinchoff is applied to a second gate electrode 102 of the duel gate FETs. In this case, only a channel of the single gate FETs is opened and therefore the drain current is small. This corresponds to the operation of the FETs of a smaller gate width. As a result, a high-efficiency operation is possible with a small output.
