IPC: C08K3/00
Filed: 1986-07-07
Abstract: PURPOSE:To prevent the deterioration of performance resulting from a void, a weld line, etc. and the degradation of appearance by conducting coating molding by an epoxy resin composition containing a specific quantity of granular inorganic fillers having fixed sphericalness. CONSTITUTION:An epoxy resin composition containing granular inorganic fillers having spheroidicity of 0.5-1.0 in the Wadel's sphericalness degree by 10-100% to the whole inorganic fillers is used. Silica powder, alumina powder, etc. are cited as the inorganic fillers. The flowing properties of the epoxy resin composition 6 pressed in from a gate 5 are improved to a power transistor body 3 with a radiator plate 2, and the composition smoothly flows on not only the surface side of the radiator plate 2 but also the back side. Consequently, the resin composition 6 flows at approximately the same velocity both on the surface side and the back side of the radiator plate 2, and the spatial section of the surface side of the radiator plate 2 and the spatial section of the back side are filled with the resin composition approximately simultaneously. Accordingly, a void and a weld line, etc. resulting from the ununiformity of the flow of the resin composition 6 are not generated.

IPC: H04N5/10
Filed: 1987-06-26
Abstract: PURPOSE:To display a synchronizing signal displayed on a cathode-ray tube correctly without being bent by improving an waveform after AC coupling by a capacitor to eliminate phase shifts. CONSTITUTION:The charging/discharge time constant of a capacitor is switched by using a vertical synchronizing signal subjected to synchronizing separation in a device where a synchronizing signal or a composite video signal are fed to the synchronizing separator circuit by AC coupling through a capacitor. The charge/discharge time constant of the capacitor sending a video signal to the synchronizing separator circuit is reduced by using the vertical synchroniz ing separation signal extracted from the output of the synchronizing separator circuit thereby improving the waveform shown in a figure C to the waveform shown in a figure E to eliminate the phase shifts. Thus, the the bending of the equalized pulse on the cathode-ray tube is eliminated.

Title: Parts supplying device
Inventor: AOYAMA YOSHITAKA
IPC: B23P19/00
Filed: 1987-06-26
Abstract: PURPOSE:To perform supply of parts at a high reliability by providing a magnet for sucking and holding a part at one of the forward end parts of a supply rod composed of an outer and an inner shaft for pushing out the part forcedly by relative displacement of both shafts. CONSTITUTION:If the whole body of a supply rod 9 advanced sufficiently, a regulating pin 14 fixed at an inner shaft 11 contacts a stopper member 17 fixed at a stationary member. The advance of the inner shaft 11 itself stops there, but an outer shaft 10 continues advancing while compressing a coil spring 13, so a part 19 is forcedly taken apart from a magnet 12 at the forward end of the inner shaft 11. Suction force of the magnet 12 is thus decreased, until finally the part 18 gets off the forward end of the outer shaft 10 to be supplied into a hole 20 in a counter part 19. Supply of parts can thus be realized at a high reliability.

Then, a phase shifter 20 delays a video signal by 33 deg. and the delayed signal is inputted to the said circuit; and the demultiplexer 22 samples carriers, classified by colors, at 90 deg. and 0 deg.. An NTSC system video signal EM is expressed by the equation (where omegasc is the angular frequency of the carriers classified by the colors), so this is delayed by 33 deg. and then sampled at 90 deg. to obtain a component EI, or sampled at 0 deg. to obtain a component EQ. Thus, the separation of the color difference signal and the demodulation of the color signals are carried out successively.
