Title: Speed change control method of automatic transmission
Inventor: IWATSUKI KUNIHIRO
IPC: F16H59/44
Filed: 1989-10-12
Abstract: PURPOSE:To perform gear change with small gear change shock by reading judgement for gear change as judgement for gear change to other intermediate step when there is such judgement for gear change into a gear change step in which a first change gear section is jumped over by two steps or more from one intermediate step and a second change gear section is switched. CONSTITUTION:When there is judgement for gear change for jumping over from a second speed step into a fifth speed step, supply command of a brake B2 is given. In this case, usually at the time of this gear change, simultaneous gear change of a first change gear section 60 and a second change gear section 40 of supply of brake B2 and drain of brake BO is done. But, only supply command of brake B2 is done here so that gear change of the change gear section 60 only is done. That is, gear change from the second speed step to the fifth speed step in a gear change line drawing is read as a gear change line from the second speed step to a fourth speed step. For this reason, single gear change from the second speed step to the fourth speed step is done. After that, acceleration is done. When a gear change line from the fifth speed step to a sixth speed step is crossed, single gear change from the fourth speed step to the sixth speed step is done, and it is simultaneously returned to a gear change line from the third speed step to the fifth speed step.

Title: Method for measuring and correcting dynamic balance
Inventor: MITSUI MASAMICHI
IPC: G01M1/38
Filed: 1984-12-17
Abstract: PURPOSE:To reduce the residual unbalance due to correction errors, by working to correct the other correction surface based on the combine vector between unbalance vectors, one left on the initial correction surface and the other left thereon after the correction. CONSTITUTION:Unbalance vectors UL and UR on the right and left correction surfaces are measured and one (for example, UR) is worked to correct. Thereafter, the residual unbalance VRO in the correction is measured to be combined with the other unbalance vector UL previously measured. According to the combined vector UL', the other correction surface is worked to correct. Thus, the residual unbalance about the surface (right) previously corrected can be cancelled statically by the subsequent correction thereby having the residue of the static unbalance.

Title: Disk type recording/reproducing device
Inventor: OKAMOTO KOJIRO
IPC: G11B17/028
Filed: 1987-10-21
Abstract: PURPOSE:To reduce a vertical load for a motor and to prolong a life by providing a clamper which changes a force depressing a disk onto a turn table in correspondence with the size of the turning force of the motor. CONSTITUTION:When the large turning force can be obtained when the motor 2 changes from a still into a starting state. If a large current is caused to flow, the large current flows in an electromagnet 8 and it generates a large magnetic force, and therefore a large repulsion occurs between a permanent magnet 7. The clamper 5 is pressed in the direction of the turn table 4 and consequently, a reproducing disk 1 is strongly clamped. When the reproducing disk 1 is increased to the necessary revolutions, the small current for maintaining the rotation is caused to flow in the motor 2, and the magnetic force of the electromagnet 8 necessarily becomes small, whereby a clamping force becomes small as a result. Thus, the load for a motor bearing, which occurs by the clamping force becomes the minimum require, and the life of the motor can be prolonged.
