Title: Rotary coating apparatus
Inventor: URANO HIDEYUKI
IPC: H01L21/027
Filed: 1990-11-29
Abstract: PURPOSE:To prevent the adhesion of the splush of a coating material solution to the rear of a substrate by providing an annular straightner having inner peripheral part disposed closely to the rear of a substrate and an air supply ring having many jet orifices injecting compressed air to the rear of the substrate, at parts closer to the center than the inner peripheral part of the straightner, from below. CONSTITUTION:A resist is dripped on a substrate 1 in a stationary state from a solution nozzle 13 and, subsequently, the substrate 1 is rotated at predetermined rpm not only to expand the resist in predetermined film thickness but also to shake off the excessive resist from the substrate 1. When the rotation of the substrate 1 is continuted, a solvent is gradually evaporated from the resist and the resist increases in its viscosity and the expansion of the resist is stopped. At this point of time, a washing solution is discharged to the rear of the substrate 1 from a washing solution nozzle 16 to wash the rear and end surface of the substrate 1. Thereafter, the discharge of the washing solution is stopped and the rotation of the substrate 1 is subsequently stopped to complete the coating with the resist. By this method, the yield in manufacturing can be enhanced.

Title: Case for neon transformer
Inventor: YAKUTA TERUYUKI
IPC: H01F38/08
Filed: 1992-12-11
Abstract: PURPOSE:To reduce the size of a case for neon transformer by increasing the degree of freedom in design of the case and to reduce the occurrence of insufficient insulation caused by water intruded into the case and, at the same time, to prevent the section between a locking member and the case from being rusted. CONSTITUTION:A side section 2, guide groove 6, and locking member 4 constituting the title case 1 are integrally formed by the extrusion molding of aluminum and a bottom plate 3 is fixed to one opening of the side section 2 by welding. When the case 1 is constituted in such a way, the degree of freedom in design of the case 1 is increased and the case 1 can be miniaturized. In addition, since the guide groove 6 is not joined to the side section 2 differently from the conventional example, the occurrence of insufficient insulation caused by water intruded into the case can be reduced after the case 1 is filled up with an insulating compound. Similarly, since the locking member 4 is not joined to the side section 2, the section between the member 4 and case 1 can be prevented from being rusted.

Filed: 1989-12-25
Abstract: PURPOSE: To adjust deformability of a shaft with characteristics of a bone cortex vessel by weakening flexural rigidity of the shaft at a distal part from a joint. CONSTITUTION: A welded seam 4 which connects a half shell 2 forming an inner central part of a shaft 1 with a half shell 3 forming an outside part, does not extend for a total length of the shaft 1.
