Title: Inverter circuit
Inventor: MURAKAMI YOSHINOBU
IPC: H02M7/521
Filed: 1990-01-13
Abstract: PURPOSE:To reduce the number of parts and the cost by constituting a bridge circuit of electrostatic induction thyristors and driving the upper electrostatic induction thyristor with a secondary voltage induced in the secondary winding of commutation coil in a driving circuit arranged on the side of lower electrostatic induction thyristor. CONSTITUTION:Upon making an input VG1 to L level, transistors Tr31, Tr32 are turned ON and an electromotive force is induced in a commutation coil n31. Consequently, an SI thyristor Th1 is turned ON. Both SI thyristors Th1, Th3 are subsequently turned ON. Upon making the input VG1 to H level, the transistors Tr31, Tr32 are turned OFF and a counter electromotive force is induced thus turning the SI thyristors Th1, Th2 OFF. In similar manner, SI thyristors Th2, Th4 are switched with an input VG2 on the side of an SI thyristor Th4 thus performing inverter operation.

Title: Sliding member of cast iron to be used in internal- combustion engine and manufacturing method of the same
Inventor: TAKAGI MUNEYA
IPC: C21D5/00
Filed: 1983-01-18
Abstract: PURPOSE:To enhance anti-abrasion characteristic by arranging spot-formed re- molten parts, which are obtained through eduction of rapidly heated and remolten cementite by utilization of the high-density energy heating source such as electron beam, dispersed in a great number on the slide surface of a sliding member made of cast iron. CONSTITUTION:Cementite 3 is rapidly heated and remolten by irradiating laser beam in spot-formed in a great number as dispersed in a zone approx. 50mm. from the upper dead point 2 of a piston top ring at a treated area ratio of 45%. The cementite 3 is assured in contact with the piston ring 6 at all times by giving a gap 5 between these cementite spots 3 seen in the axial direction a width narrower than the thickness B of piston ring 6, which reduces effectively wear of the cylinder bore surface. If a micro-dimension of approx. 1mm.phi is remolten, good remolten surface condition can be obtained, and because graphite is distributed around the remolten parts, these will work as oil pans to ensure maintenance of good lubricating performance.

Abstract: PURPOSE: To raise the ridigity and to make a rotary part light and to make it possible to raise the critical speed by a method wherein a centering plate of the front stage impeller is combined with a side plate of the rear stage impeller so as to make  it actually a unitary construction where the impellers are solidly implanted on a  shaft of a big diameter.  
     CONSTITUTION: A mouthring part 3a of the second stage impeller is extended in the axial direction and the end part of said extended part 3b is combined with a centering plate 2a of the first stage impeller 2. The extended part 4b of the mouthring part 4a of the third stage impeller 4 is similarly combined with the centering plate 3c of the second stage impeller, both of the extended parts 3b, 4b are provided with a  passage 5. Further the first stage impeller 2 and the third stage impeller 4 are combined with the shaft 6. In this way, by combining actually the impellers with the  shaft having a big diameter, the ridigity of the shafting is actually raised. As there  is no supporting shaft between the impellers, a rotary part becomes light and the  shaft is shortened thus the increment of the critical speed is made possible.

Abstract: PURPOSE:To enable to form HPF easily, by producing the charge corresponding to the signal amount at LPF having inverse characteristics as desired HPF, in opposite phase. CONSTITUTION:The charge group as the first sample remains at the area surrounded with the area 21 and the electrode 26 and a part of the charge group of the second sample remains at the area surrounded with the area 21 and the area 28 at the next period.
