Title: Heat transfer tube
Inventor: MURAYAMA TOMOYUKI
IPC: F28F1/40
Filed: 1985-05-29
Abstract: PURPOSE:To shorten the distance of approach run of fluid, lengthen turbulent flow area in the tube and display prominent performance of heat transfer tube by a method wherein the pitch of a spiral groove provided on the inner surface of the tube is increased gradually from the inlet port side of the tube toward the outlet port side thereof. CONSTITUTION:A distance from the inlet part of the heat transfer tube 1 to the turbulent flow area is shorter than before and the pitches of the grooves 2, 2 in a transit area, in which the fluid arrives at a perfect turbulent flow area, is shorter than before. The pitches P of the grooves 2, 2 in the boundary part between the transit area and the turbulent flow area are substantially equal to the same of conventional tube. Since the tube is formed so that the pitches P of the grooves 2, 2 are increased gradually toward the outlet port side of the tube and the friction coefficient lambdag of the flow of liquid is reduced, therefore, increase of pressure loss of the liquid is reduced and the energy of flow of liquid is not deteriorated so much. Accordingly, good turbulent flow is generated along the whole length of the heat transfer tube 1 substantially and the heat transfer performance, more excellent than before, may be displayed.

Title: Bond magnet
Inventor: SUZUKI JUN
IPC: H02K1/27
Filed: 1998-04-10
Abstract: PROBLEM TO BE SOLVED: To facilitate attachment to a core and prevent occurrence of adhesion, cracking or chipping of magnets or the like, by forming divided magnets, and mating north poles with south poles by fitting. SOLUTION: When the north pole-magnetized parts 2 and south pole- magnetized parts 4 of a bond magnet 1 are coupled with each other and integrated, the same poles are prevented from being positioned side by side by varying the shape of coupled portions. Specifically, an annular bond magnet 1 is formed by mating recessed portions 3 formed at both the ends of the north pole- magnetized parts 2 with projected portions 5 formed at both the ends of the south pole-magnetized parts 4 by fitting, and attachment to a rotor core is thereby facilitated. Conversely, projected portions may be formed at both the ends of the north pole-magnetized parts, and recessed portions may be formed at both the ends of the south pole-magnetized parts. In addition, since the magnetic field is oriented in the same direction during molding unlike polar anisotropic type, molds can be easily fabricated.

Title: Vibration proofing device for photoreceptor drum
Inventor: SATO MASARU
IPC: G03G21/00
Filed: 1994-05-30
Abstract: PURPOSE:To obtain a vibration proofing device for a photoreceptor drum reducing the vibration of a photoreceptor drum by providing a specified cantilever and constituting the cantilever to absorb vibrational energy applied to the drum. CONSTITUTION:A pair of cantilevers 2 having equivalent characteristic frequency to the photoreceptor drum 1 is fixed on a fixed piece 10 provided perpendicular to a center shaft in the center of the inside of the drum 1. The cantilevers 2 are fixed to be symmetric with reference to the center shaft of the drum 1 on the surface side of the fixed piece 10. Even though the vibrational energy is applied to the drum 1 when the drum 1 is rotated centering around a rotary shaft 3, by such constitution, the cantilever 2 absorbs the vibrational energy (the cantilever 2 is vibrated instead of the drum 1), so that the vibration of the drum 1 is reduced. By reducing the vibration, image quality is improved without making the drum 1 heavier and noise made by the vibration of the drum is reduced.
