Title: Image forming device
Inventor: MAEKAWA KAZUNOBU
IPC: G03G15/16
Filed: 1995-11-13
Abstract: PROBLEM TO BE SOLVED: To remove residual toner on a transfer drum without adversely influencing a photoreceptor drum by uniformly electrifying the residual toner on a transfer drum with the same polarity as the residual toner by an attraction charger. SOLUTION: By turning on the attraction charger 204 on which an attracting roller 212 abuts in a state where the transfer drum 202 is still driven after finishing a series of copying operation, the residual toner on the drum 202 is uniformly electrified to have reverse polarity to the rolarity which makes the toner adhere to the drum 202. The residual toner electrified in such a way is more strongly electrified to be efficiently recovered by a fur brush roller 225 rotated in a reverse direction to the rotating direction of the drum 202. Oil and toner somewhat adhere to the roller 212 but they are removed by a scraper 212a abutting on the roller 212. Even though they remain a little, the image is prevented from being adversely influenced in comparison with the case they remain on the drum 206.

Title: Karaoke device
Inventor: TSURUMI KANEHISA
IPC: G10K15/04
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To facilitate the selection of music in a karaoke device, and produce the game property. SOLUTION: In addition to song number corresponding to karaoke song in 1:1, random selection numbers of genre designated song number and singer designated song number are set. When a genre designated song number is inputted, one song is selected at random from the songs of the genre designated by this song number, and this song is played. Since the song number is formed of singer number + song number by words, one song is selected, when a singer designated song number is inputted, at random from the song numbers having this singer number, and played. Thus, a song can be properly selected even when its song number is not clearly known, and game property can be imparted to the selection of song.

Abstract: PURPOSE:To obtain a chair which can be easily moved for movement and is stably set for use by providing a rotatable ball protruded from the tip face of each leg and supporting the chair via a spring at the tip section. CONSTITUTION:A ball type caster 4 provided in a hole 3a at the tip of a leg 3 is formed integrally with a sliding tube 5 by caulking and the like. An extruding force toward the tip side of the leg 3 is applied to the caster 4 from the depth side of a guide tube 6 guiding the outer face of the sliding tube 5 via an adjusting screw 7, a spacer 8 and a spring 9, however the caster 4 is restricted by a stopper 6a, and the protruded quantity of the ball 10 of the caster 4 from the leg 3 is limited to ds. If the force applied from the tip of the ball 10 is larger than the extruding force by the spring 9, ds is made shorter. For only the tare weight of a chair 3, ds>0, when a person is seated on the chair 1 and a reaction force is applied from the tip 3b of the leg 3, the spring 9 is compressed, the caster 4 is retreated, thus causing ds=0, and the tip 3b of the leg 3 is brought into firm contact with the floor.
