Patent JP-2008522672-A (JP)
IPC: A45D34/04
Filed: 2006-05-31
Abstract: An apparatus for applying a cosmetic, such as mascara to eyelashes, includes a handle, a stem, and an applicator head coupled to the stem and supported for rotation relative to the handle. An actuator moves the applicator head in a rotational oscillating motion, in which the applicator head automatically rotates in both a first rotational direction and a second rotational direction in response to operation of the actuator. Additionally or alternatively, the actuator may also radially translate the applicator head, move the applicator head through an angle of rotation less than 360 degrees, and vary the rotational speed of the applicator head. The applicator head may include protrusions that are spaced to define gaps during rotation, thereby to promote coverage and separation of eyelashes.

Filed: 2008-01-22
Abstract: <P>PROBLEM TO BE SOLVED: To solve a problem that, when illumination is carried out with an LED in image reading of a sensing camera in conventional cases, the sensing camera needs more brightness at a peripheral part than a center part of the screen, so that a plurality of LEDs headed toward necessary directions must be combined to secure irradiation angles, which leads to plenty of power sources consumed of a digital camera and decrease of the photo-taking number.  <P>SOLUTION: Power consumption for illumination is reduced by dividing light from an LED with an incident-face lens made in nearly a V shape so that it expands at an angle α in a length direction of the photo, and further focusing it with an irradiation-face lens as a convex lens with each divided center line as an axis, which enables to obtain a nearly rectangular irradiation range with light of just one LED.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To provide a bidirectional reverse blocking battery switch.  <P>SOLUTION: An aspect of the invention is an improved die layout for the bidirectional reverse blocking battery switch. In one aspect, two switches do not contact each other at their ends, but are oriented so as to be juxtaposed within a die package. The constitution reduces the total switch resistance with regard to a given die area; in many cases, the resistance is fully reduced so as to avoid a usage of a back metal for conforming to a resistance standard. The back metal is eliminated so as to reduce the total cost of the die package and eliminate potential failure mode, due to manufacturing of the back metal. In some other aspects of the invention, increase in pin connections and a pin pitch can be allowed. Redundant connections for large current connections are formed. The electrical resistance and the thermal resistance are reduced, and as a result, the cost for manufacturing or implementing the die package is minimized.  <P>COPYRIGHT: (C)2009,JPO&INPIT
