IPC: G11B5/55
Filed: 1983-12-08
Abstract: PURPOSE:To reduce step error and to improve overall step accuracy by using two members to the screw shaft coupling part of a step actuator and connecting both members with an elastic substance. CONSTITUTION:The rigidity is reduced at a coupling part 17 between a floppy disk attachment part 28 at the end part of a lead screw shaft (c) and a lead screw part. Thus the step error can be reduced during one rotation of a rotor (b) and the overall step accuracy R is improved. The different members are used to a male screw part 16 of the shaft (c) and the part 28 respectively without using a coupling part unified with the shaft (c). Another member, e.g., a metallic piano wire 29 having flexibility or elasticity is used to connect those two different members by adhesion or melt-sticking 30. While a close-adhesion coil spring 32 is used to a coupling part between the screw part 16 of the shaft (c) and the part 28. Thus it is possible to keep the flexibility of the shaft (c) and also reduce the rigidity of the shaft (c).

The stator core 4 comprises a plurality of teeth 8 for guiding the magnetic flux to the side of a rotor in the laminated layer of many electromagnetic steel plate sheets, punched in the same shape, and yokes 9 for linking the teeth and slots 10, being winding spaces. In the stator core 4, a yoke width (y) is set as the value indicated by y=nt/π with respect to the teeth width (t). For example, in 4-pole 24-slots, the yoke width (y) is set as y=5.7mm with respect to the teeth width (t) of t=3mm, which is 1.9 times. Thus, the flux densities of the yoke part and the teeth part of the stator core are made to be approximately equal, and the compact configuration of the motor is achieved.

Abstract: PURPOSE:To shorten a time in which an air-fuel ratio is displaced by a method wherein an average of control of an air-fuel ratio is displaced to the lean side or the rich side by a given amount when a pressure of fuel fed to a fuel injection valve is switched to the low pressure side or the high pressure side. CONSTITUTION:A lean and rich signal outputting means M1 to output a signal responding to lean and rich mixture of an air-fuel ratio reflected in exhaust gas is provided. An air-fuel ratio of air-fuel mixture is increased or decreased through given integrating operation by means of an air-fuel ratio increasing decreasing means M2 according to a detected signal for lean and rich, and feedback control of an average of an air-fuel ratio is performed. A fuel pressure switching means M3 to switch a pressure of fuel fed to a fuel injection valve IJ based on the running state of a vehicle is provided. When a pressure of fuel is switched to the low pressure side or the high pressure side, an average of control of an air-fuel ratio regulated by the air-fuel ratio increasing decreasing means M2 is displaced to the lean side or the rich side by means of an air-fuel ratio switching means M4. This constitution causes convergence of an average of an air-fuel ratio to a target value without integrating operation.

Title: Intake air amount control device for engine in vehicle with automatic transmission
Inventor: WATANABE YOJI
IPC: F02D31/00
Filed: 1988-09-16
Abstract: PURPOSE:To eliminate the generation of an engine stop, even when a brake is applied, further to enable the responsibility to be improved of an idle speed control in a creep running condition by suppressing a decrease amount of intake air in this condition in accordance with a car speed in that time. CONSTITUTION:In a creep running condition at a car speed of about 3.5km/h, when a feedback control is performed of intake air amount, generation of an engine stall is considered due to the smallness of an absolute amount of intake air by a small amount of transmission load and due to the decrease of an engine speed itself to the vicinity of an idle target speed, and using the engine speed with only its change serving as the parameter, a feedback value of intake air amount control, acting essentially to a minus side, can be limited to a value considerably smaller than the essential value. In this way, the engine speed can be focused to the stable idle target speed.
