Patent JP-H08326685-A (JP)
Title: Motor-driven blower
Inventor: YOSHIZAWA HIROYUKI
IPC: F04D17/10
Filed: 1995-06-05
Abstract: PURPOSE: To suppress air flow which flows from a casing side toward a space part sectioned between a centrifugal fan and a fixed fan so as to prevent reduction of a suction property by arranging a means for suppressing flow of air between the plate of the centrifugal fan and a stationary member consisting of the fixed fan or the casing. CONSTITUTION: When an electric blower A is driven, air sucked from an intake port 22a flows out from a discharge hole 12b outward passing through the intake opening 41 of a fan cover 40 by rotation of a centrifugal fan 21 after air flows into a casing 14 while it is guided by the guide wall 31 of a fixed fan 30. At this time, air in a space part S which is sectioned between the 2 plate 23 back surface of the centrifugal fan 21 and the fixed fan 30 flows to an outer peripheral side, and it becomes a low pressure condition. Air in the casing 14 becomes a high pressure condition, and it flows through the clearance of a ball bearing 16. In this case, flow of air in the space part S is suppressed by a plurality of annular projections 34a to 34c.  It is thus possible to prevent reduction of suction property caused by air flow which flows from the back surface side of the fixed fan 30 passing through the space part S.

Title: Multi-color ink ribbon device
Inventor: MIYASAKA HIROYUKI
IPC: B41J35/16
Filed: 1990-05-28
Abstract: PURPOSE:To prevent a mixed compound ink from sticking to the texture surface of a following multi-color ink ribbon again, if a multi-color ink ribbon slides to generate an ink pool by providing a groove-like non-contact part at a place with which the color border line of the multi-color ink ribbon comes in contact. CONSTITUTION:A multi-color ink ribbon slides over a protrusion 2 located in a ribbon sliding part of a multi-color ink ribbon device 1. A groove 6 is added to the protrusion on a multi-color ink ribbon color border line of the multi-color ink ribbon device 1, and the multi-color ink ribbon 3 slides through the groove 6. As a result, the ink becomes trapped in the groove 6, if an ink pool generates. therefore, if a mixed compound ink sticks to the protrusion of the multi-color ink ribbon device, the mixed compound ink 5 no longer attaches to the texture surface of the multi-color ink ribbon border line, when a following multicolor ink ribbon 3 slides over the protrusion.
