Abstract: A liquid discharge head includes a liquid discharge substrate that has a discharge-orifice row, pressure generating elements, and pressure chambers. The liquid discharge head discharges a liquid in a block-by-block manner using sequential driving. The discharge-orifice row is disposed so as to incline at an angle ?=Arctan (d1/d2) relative to a direction extending orthogonal to the conveyance direction of the medium, in which d1 (?m) is a disposition spacing of the discharge orifices in the discharge-orifice row in the conveyance direction and d2 (?m) is a disposition spacing of the discharge orifices in the discharge-orifice row in the direction orthogonal to the conveyance direction. A partition wall is formed between adjacent pressure chambers so as to separate the adjacent pressure chambers from each other. The partition wall has a communicating portion that communicates the adjacent pressure chambers with each other.

Abstract: An electric hair clipper includes a hair thinning comb attachment detachable to a housing provided with a cutter assembly. The comb attachment is formed with a row of hair guiding slots which is in parallel and juxtaposed relation with the cutting edge of the cutter assembly for guiding the hair past the cutting edge in the process of hair thinning operation. A rotary adjustor dial is mounted on the housing and is drivingly connected to the comb attachment for varying the relative position of the comb attachment to the housing and therefore the distance between the row of the hair guiding slots and the cutting edge, thus adjusting the cutting length of hair intended by simple manipulation of the rotary adjustor dial.

Abstract: A golf putting practice device comprises a ramp having a hole therein and a lifter for removing the ball from the hole. The ball lifter includes a lifting lever disposed in the hole and rockable between a non-actuated position for receiving a ball and a vertically actuated position for discharging the ball out of the hole in a rearward direction with respect to the lowest front end of the ramp direction. A slanted track receives the discharged ball and permits it to roll forwardly along one side edge of the ramp. A ball returner springs the back to the player.
