Title: Disk driving device
Inventor: OKA HIROSHI
IPC: G11B17/028
Filed: 1989-04-11
Abstract: PURPOSE:To prevent defective chucking of a disk due to dust or the like by providing plural grooves in a symmetrical position to a rotary center of a driving member on a disk medium receiving surface of the driving member. CONSTITUTION:Comparatively wide and deep grooves 3b are formed on the disk receiving surface of a turntable 3'. The grooves 3b are provided radially with their eight stripes on the disk receiving surface in an annular shape, and the positions of the individual grooves 3b are settled symmetrically to the center of the turntable 3' in order not to generate unbalance in weight. Consequently, when the disk is slipped due to a foreign matter such as dust or the like the foreign matter between the disk and the disk receiving surface of the turntable 3' is kicked out into the grooves 3b by the disk slippage, so as to be removed from between the disk receiving surface and the disk. By this method, the normal disk chucking state is restored immediately, and hence the normal access to the disk is feasible.

Title: Motor reel with charge control function
Inventor: KOBAYASHI TAKEHIRO
IPC: H02J7/04
Filed: 1990-04-03
Abstract: PURPOSE:To allow constant current control and to eliminate a charger provided with a constant current circuit independently from a motor reel by providing a control means for detecting the battery voltage every predetermined time and controlling the time interval for closing a charging circuit according to thus detected battery voltage. CONSTITUTION:A motor reel comprises a charging circuit 42 connected between an input terminal 32 and an output terminal 30 and opening/closing a circuit between the input terminal 32 and the output terminal 30, and a control means 44 for detecting the battery 46 voltage every predetermined time and controlling the time interval for closing the charging circuit 42 according to thus detected voltage. Since the conductance of battery 46 charging current varies according to the potential difference between the input terminal 32 and the output terminal 30, the control means 44 controls the closing time, i.e., the duty ratio, of the charging circuit 42 according to the variation of the battery 46 voltage. Since the charging current can be quantified, an independent charger is not required while furthermore the battery 46 can be charged with approximately constant current when the battery 46 is connected with a motor reel body 12.

Inventor: INOUE KAZUTOSHI
IPC: E02D15/06
Filed: 1988-04-14
Abstract: PURPOSE:To prevent splashing of a binder fed through a tremie pipe, by a method wherein a bottom plate is situated to the lower end part of the tremie pipe and window holes are formed in a side wall, and a plunger slidable and having buoyancy is insertedly engaged in the pipe. CONSTITUTION:A bottom plate 11 is placed to the lower end of a cylindrical metallic pipe, and window holes 12 are formed in the side thereof to form a tremie pipe 10. A plunger 13 having a ring 15 secured to the upper part of a disc-shaped buoyant body 14 having a conical upper surface through stays 16 is insertedly engaged internally of the tremie pipe. Since the plunger is slowly lowered as its weight is balanced by means of buoyancy and friction between the tremie pipe and the plunger, this constitution enables prevention of splash of a binder and mixing of it with water.
