Title: Digital audio signal reproducing device
Inventor: SAKASHITA SHIGEO
IPC: G11B27/00
Filed: 1991-12-13
Abstract: PURPOSE:To revise a reproducing speed without revising the clock frequency of a driving system in a digital audio reproducing device. CONSTITUTION:A driving system of a CLV servo circuit 108 and a signal processing circuit 115, etc., are operated by synchronizing with the system clock of a constant frequency from a system clock oscillation circuit 121. Audio data outputted is read successively by synchronizing with the regenerative clock of a variable frequency from a regenerative clock oscillation circuit 122 and outputted to an L/R separation circuit 116 after the audio data is written in a data memory in a reproducing speed control circuit 123 by synchronizing with the system clock. At this time, the driving system is made a pause state by a pause control signal when data amount written in the data memory is arrived at a prescribed amount and the pause state of the driving system is released and returned to a reproduction state when the data amount has a margin. Thus, the audio data is reproduced by synchronizing with the regenerative clock while holding the driving speed of the driving system of a CD to a speed corresponding to a standard reproducing speed.

Filed: 1991-12-13
Abstract: PURPOSE:To provide a stabilized magnetic levitation mechanism at low cost by disposing a stopper closely to the underside of an upper balance point among two balance points where the gravity of levitating part balances with a levitating force which is the sum of attracting force and repelling force to be produced at an intermediate part by means of permanent magnets disposed at upper and lower securing parts. CONSTITUTION:Permanent magnets 4u, 4d are fixed, respectively, to upper and lover securing parts 2u, 2d. Permanent magnets 3u, 3d are further fixed to the opposite vertical ends of a levitating part 1 interposed between the securing parts 2u, 4u. The permanent magnets 4u, 3u oppose with unlike poles to be attracted each other whereas the permanent magnets 3d, 4d oppose with like poles to be repelled each other. Among two balance points where the gravity of the levitating part 1 balances with the levitating force, i.e., the sum of attracting force and repelling force, a stopper 5 is disposed closely to the underside of upper balance point. According to the constitution, a downsized stabilized levitation mechanism can be formed at low cost.

IPC: G03G15/04
Filed: 1988-12-27
Abstract: PURPOSE:To prevent a mistake in detection from occurring by performing original detection processing(sampling) plural times by a light emitting and receiving element, integrating light receiving levels and setting the integrated light receiving level as a level for decision. CONSTITUTION:The light receiving levels inputted in the light receiving elements 1b-4b are sampled plural times and integrated.

Title: Bristle material for brush
Inventor: NIIZAKI YUICHIRO
IPC: A46D1/00
Filed: 1998-11-24
Abstract: PROBLEM TO BE SOLVED: To provide a precise finishing surface extremely efficiently by adding diamond abrasive grains with a specific grain size and forming a bristle material from a filament having a specific filament diameter and containing diamond abrasive grains. SOLUTION: Diamond abrasive grains used for a brush bristle material is 0.1-100 μm in grain size. When grain sizes are smaller than this range, polishing effect is little provided, and when grain sizes are larger than this range, fiber forming ability and toughness of a filament are reduced. Contents of the diamond abrasive grains to a synthetic resin is 5-30 wt.%, preferably 15-25 wt.%. When the contents is lower than 5 wt.%, polishing efficiency is bad because sufficient amount of diamond abrasive grains do not expose from a filament surface, and when the contents exceeds 30 wt.%, the fiber forming ability and the toughness of the filament decrease. Diameter of a filament containing diamond grinding grains is 0.2-1.5 mmϕ, preferably 0.25-0.6 mmϕ.  When the diameter is smaller than 0.2 mmϕ polishing effect is little provided, and when the diameter exceeds 1.5 mmϕ, no precise machining can performed.

Title: Caster mechanism for chair
Inventor: SUZUKI YOSHIFUMI
IPC: B60B33/00
Filed: 1989-12-21
Abstract: PURPOSE:To improve seating safety, and to facilitate the movement of a chair and to prevent the damage of a shoe by providing the lower face of a base with a caster which a spring energizes to protrude for its freely getting in and out, and making a load acting onto the base immerse the caster into the base against spring energizing force. CONSTITUTION:When no one takes a seat, a ball 20a protrudes from the lower face of a leg 14 of a base 13 under the spring force of a compression spring 21 to form a gap S between the lower face of the leg 14 and a floor face F. The ball 20a can therefore make a chair freely move. On the other hand, when someone takes the seat to give a load onto the chair, the compression spring is therefore compressed to immerse the ball 20a into the leg 14. Thus the lower face of the leg 14 comes into contact with the floor face to control the movement of the chair for stabilizing it.
