  • Patent number: 11303141
    Abstract: A protection circuit for a battery includes a discharge FET, a control circuit, a first small-signal FET, and a second small-signal FET. The discharge FET connected in series to a battery interrupts an electric current. The control circuit switches on or off the discharge FET. The first small-signal FET connected in parallel between a gate (G) and a source (S) of the discharge FET is switched to an ON state, to set a gate voltage of the discharge FET to an OFF-state voltage. The second small-signal FET connected in parallel between G and S of the discharge FET detects a voltage between a drain (D) and S of the discharge FET. When the voltage between D and S of the discharge FET exceeds a preset voltage, the second small-signal FET is switched to an ON state to set the gate voltage of the discharge FET to the OFF-state voltage.

  • Publication number: 20140267589
    Abstract: An omnidirectional image storage unit stores frames of panoramic image shot while moving on the route, a route information storage unit stores route information indicating nodes and branches on the route, and a correspondence information storage unit stores correspondence between each frame and each point on the route. A data updating unit successively updates a current position and a sight direction based on a user's input. An image cutout unit reads out a panoramic image corresponding to a current position and cuts out a field of view image that constructs a field of vision in a sight direction. A route mapping unit creates a route map indicating a current position and a sight direction superimposed upon a plan view of the route. An image display unit displays the field of view image and the route map side by side.

  • Patent number: 5792545
    Abstract: On a surface of a decorative paper, vessel perforation of natural wood is reproduced by an offset groove (100) consisting of three steps of embossing grooves (110, 120, 130) of the nesting structure. Respective grooves are such that they are deeper according as positions thereof shift to the internal, and are disposed in a manner to be eccentric in a length direction. Within the groove, a convex bank portion (140) in which the bottom surface is linearly protruded is formed. An embossing plate for processing such an offset groove is prepared on the basis of a vessel cross section pattern inputted by using natural wood. The inputted plane vessel cross section pattern is replaced by an approximate elliptical figure. A three-dimensional virtual vessel perforation model is determined by calculation using the elliptical figure. Equi-depth lines for set predetermined depths are extracted from the three-dimensional model and contour figures of embossing grooves (110, 120, 130) are obtained.
