Title: Rolling bearing
Inventor: KANEKO TOSHIAKI
IPC: F16C33/62
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To secure the excellent rolling service life, and maintain density small by forming at least either of a bearing ring and a rolling body out of ceramics having the composition by adding zirconia by a specific quantity to alumina. SOLUTION: When zirconia is added to alumina as ceramics used for either of a bearing ring and a rolling body, a grain boundary of alumina is strengthened, strength is increased, and the rolling service life is also lengthened. It is necessary to add zirconia by at least 5 wt.% or more therefor. However, since the rolling service life is shortened when an adding quantity of zirconia too much, it is necessary to set a zirconia adding quantity not more than 50 wt.%. When the adding quantity of zirconia is not more than 50 wt.%, density of zirconia-added alumina can be maintained small as illustrated to thereby restrain an increase in a rolling body load by centrifugal force generated when the rolling body rotates at a high speed.

Title: Starting and control device for dc shunt motor
Inventor: MIYAZAKI SHUNICHI
IPC: H02P1/18
Filed: 1994-04-25
Abstract: PURPOSE:To cope with low response and variations in supply voltage and the surrounding temperature of a motor while avoiding the short-circuit and overcurrent, by providing a delay time correcting means that shortens the delay time more for higher supply voltage and lengthens the delay time more for lower supply voltage. CONSTITUTION:A starting and control device 5, a delay time correcting means, for a d.c. shunt motor 4, produces armature current starting signal output to start the motor when a delay time, preset based on supply voltage and motor temperature, has passed after the start of output of field driving signal. This energizes the armature 2 after a magnetic field is generated in the field coil 3, which prevents the occurrence of short circuits or overcurrent. When supply voltage is sufficient or motor temperature is low, the delay time is minimized. This enables the improvement of the starting response of the motor 4.

Title: Data receiving circuit
Inventor: SAEKI HIROAKI
IPC: H03M13/00
Filed: 1988-04-08
Abstract: PURPOSE:To perform reproducing close to actual sounds by deciding a receiving condition before N hours, fetching information containing errors as effective information when there are few errors in the condition, limiting it within a number-of-sample-bits range even when the error information is reproduced at the time of a demodulation. CONSTITUTION:When a packet omission is detected by a packet omission detecting circuit 2, the demodulation of the signal during the N hours is inhibited by an expanding circuit 8. When it cannot be corrected by an error detecting circuit 3, the receiving condition N hours earlier which is the output of an error deciding circuit 5 is considered by a data control circuit 6, when it is comparatively good transmission condition with few errors, a packet in which the errors are detected is judged to be the information with few errors and it is outputted to a memory 7. A data protecting circuit 10 considers that the error information is contained and a modulation PCM signal limits the polarity of differential data to a considered value within a modulation bit range. When the error information is demodulated, it becomes a value different from an actual value temporarily, however, it is leaked by a data holding circuit 11, therefore, it becomes a value close to the actual value in a comparatively short time.
