IPC: F02N11/08
Filed: 1979-09-05
Abstract: PURPOSE: To shorten the time from the initial explosion to complete explosion of an engine, by providing an auxiliary coil in the starting motor so that the auxiliary coil is excited when the engine speed is raised to a predetermined value.  
     CONSTITUTION: The starting motor of this invention comprises a field coil 3 and an auxiliary coil 9 turned in reverse direction to that of the field coil 3. These coils 3, 9 are connected to a generator 11 via a relay 13. since the generator 11 produces a voltage corresponding to the revolutional speed of the engine 10, the relay 13 is excited when the engine speed is raised to a predetermined value at the time of starting engine 10 and closes a realy contact 12. Resultantly, current is passed  through auxiliary coil 9 and it functions to cancel a portion of the magnetic flux  produced by the field coil 3, so that the revolutional speed of the starting motor is  raised. On the other hand, although the torque is lowered, it does not cause any difficulty since torque is not required so much in this state. Thus, it is enabled to  change the revolutional speed of the starting motor in a required manner.

Title: Junction separating structure for semiconductor integrated circuit
Inventor: TABATA TERUO
IPC: H01L21/76
Filed: 1986-05-19
Abstract: PURPOSE:To improve the integration of a semiconductor integrated circuit by diffusing a separating region upward from the surface of a substrate, and forming the uppermost part of a diffused region which is made to reach to an epitaxial layer surface. CONSTITUTION:A separating region 24 is diffused upward from the surface of a substrate 21 so that the uppermost part arrives at the surface of an epitaxial layer 22. The substrate 21 is considerably widely formed in the diffusing depth by lateral diffusing, but the surface of the layer 22 is scarcely laterally diffused to be considerably narrowed. Further, since a base region 26 is selectively diffused from the layer 22, the peripheral end is so bent as to separate from the peripheral end of the region 24. Accordingly, since the regions 26 and 24 are sufficiently separated even in the bottom of the region 26, the region 24 does not disturb the improvement in the integration on the layer 22.

Filed: 1984-06-04
Abstract: PURPOSE:To attain the proper servo control over a entire working area by varying the gain of each characteristic compensation which is applied to a servo control system according to the speed command value given to a control subject. CONSTITUTION:Both the old target position data and the speed command data on an action shaft are read out of a memory 1, and the target position data is operated 13. A position deviation is calculated 14 from the target and present position data. The present position data given from a position detector 2 is differentiated 15 to obtain the revolving speed of the action shaft. Then a deviation is calculated between said revolving speed and the speed command data. The command acceleration is obtained 17, and the acceleration of each shaft is calculated to obtain 19 a deviation. Each deviation is multiplied 28 by a gain constant, for calculation of each compensation output. The gain of each compensation is changed based on the speed command value by taking notice of a fact that the working speed of a robot suggests the robot working state. Then the characteristic compensation is possible in response to the robot working state. For this purpose, the gain constant is selected out of a table according to the command speed of the action shaft.
