Title: Suppression of higher harmonic inflow for pwm current type power converter
Inventor: DEGUCHI HIROSHIGE
IPC: H02M7/48
Filed: 1998-11-09
Abstract: PROBLEM TO BE SOLVED: To provide suppression of higher harmonic inflow the capable of restraining higher harmonic inflow by inserting an LC filter into AC side and properly selecting resonance frequency. SOLUTION: A serial LC filter, consisting of a reactor L1 and a capacitor C1, is inserted between AC power supply lines. Two or more serial resonance frequencies of the LC filter are made to exist, when the filter is seen from the AC side, so that the frequency of the higher harmonics degree with a large voltage distortion on AC side exists between the two serial resonance frequencies. It is thus possible to increase the combined impedance of the LC filter, thereby restraining higher harmonic voltage inflow.

Title: Manufacture of semiconductor integrated circuit element
Inventor: OKUMURA NOBUO
IPC: H01L21/265
Filed: 1988-12-16
Abstract: PURPOSE:To manufacture an LDD transistor, with good reproducibility, without doing damage to a substrate by a method wherein a film, for electrode use, where only a source region and a drain region at a low concentration have been made void is formed, their void positions are filled with another film, a part required for a gate electrode is left and the film used for other electrodes is removed. CONSTITUTION:A film 4 for gate electrode use is formed, via a gate insulating film 3, on a semiconductor substrate 1 other than regions to form a source and a drain 5 at a low concentration; low-concentration impurities are implanted. Then, another film 6 having an etching-resistant property with reference to said film 4 for gate electrode use is formed in said regions to form the source and the drain 5 at the low concentration. Then, the film 4 for gate electrode use in a region other than a region used to form a gate electrode 8 is removed by an etching operation while at least the regions to from the source and the drain 5 at the low concentration and the region to form the gate electrode 8 are used as a mask; after that, high- concentration impurities are implanted. For example, a polycrystalline Si film is used as the film 4 and an SiO2 film is used as another film 6. Thereby, since an anisotropic etching operation is not used, there is no danger of inflicting damage to the substrate.

The magnetic field X acts to scoop up the developer on the sleeve 8a onto the sleeve 8 and the magnetic field Y acts to scoop down the developer on the sleeve 8 onto the sleeve 8a. The developer is, therefore, surely circulated without co-rotating and the developing operation is thus executed. The images of the desired density are obtd. in this way and the unequal densities are eliminated.

Title: Bar stock working device
Inventor: NAGAMINE OSAMU
IPC: B23B13/08
Filed: 1989-12-08
Abstract: PURPOSE:To improve productivity and to prevent the waste of a bar by preventing the vibration of the bar stock with the approach of the inner diameter of the insertion hole of the spindle of a bar processing device to the diameter of the bar stock and making a finger chuck which holds the bar intrudable into the spindle. CONSTITUTION:A finger chuck 12 of a bar working device is equipped with plural finger pieces 24 and on a spindle 15 a recessed bar received to the finger piece 24 and a projecting bar engaged with the finger piece 24 are provided inside an insertion hole 14, when the finger chuck 12 is inserted into the insertion hole 14. When the chuck 12 is inserted into the insertion hole 14 of the spindle 15, the finger piece 24 comes into the recessed bar of the insertion hole 14 inside. Also, the projection bar is engaged with the space between the finger pieces 24. So, the finger piece 24 becomes movable into the spindle 15 along the recessed bar by holding the rear end of a bar stock 11. Consequently, the bar stock 11 can be fed into the spindle 15 from the front end up to the rear end. Also, the vibration of the bar stock 11 is difficult to cause because of the projection bar approaching to the peripheral face of the ball stock 11.
