Abstract: PURPOSE:To maintain the target rpm of an engine irrespective of a height where a vehicle is located by varying a reference control signal according to the atmospheric pressure with an idling regulation method whereby the amount of suction air of the engine is regulated independently from a flow control means. CONSTITUTION:An atmospheric pressure sensor 10 detects the atmospheric pressure and an atmospheric pressure detector signal Pa is output; a reference control amount output circuit 11A inputs the signal Pa from the atmospheric pressure sensor 10 and outputs a reference control signal STV in inverse proportion to the signal Pa.

Title: Data transfering method in token passing network
Inventor: KOTAKA KAZUNORI
IPC: H04L12/40
Filed: 1995-05-16
Abstract: PURPOSE: To flexibly change a communication band by recognizing the communication band assigned to an other node by each node, predicting synchronous data quantity which is possible to be generated in the future and changing its communication band by each node in accordance with a predicted value. CONSTITUTION: The normal value 23 of an A node is 100, the maximum value 21 is 90 and the present value is 89. The normal value of a B node received from the B node is 50 and the normal value of a C node is 60 in the same way. Further, it is assumed that total synchronous data quantity showing the communication band on a LAN is 300. At this time, when the both of the maximum value 21 and the present value 22 of the A node are 75% or more of the normal value 23, synchronous data quantity which is possible to be generated in a self-node in the future is predicted by allowing 50% for the maximum value 23. The predicted value in this example is 135. Because each of the normal values of the B and C nodes is 50 and 60, the normal value that the A node is possible to be extended becomes an upper limit value 190 from 300-(50+60)=190.  Because the predicted value 135 satisfies this condition, the A node changes the normal value to 135 and notifies the value to the B and C nodes.

Title: Magnetic head driver
Inventor: KISO MATAICHIRO
IPC: G11B21/10
Filed: 1986-05-23
Abstract: PURPOSE:To suppress vibrations generated at the time of positioning of a head and to position the head at high speed by detecting said vibrations by a capacitive detector and using this detecting signal to give the rotary control to a stepping motor serving as a drive source. CONSTITUTION:When a stepping motor 1 is driven to produce vibrations in a positioning mode of a head 6, the capacity limited between a slant shaft 11 and an electrode 12 varies by the rotary displacement of a shaft 2. This change of capacity is converted into the voltage by a capacity converter 13 connected electrically to the electrode 12 and amplified by an amplifier 14. This amplified signal contains also such noises undesired for suppression of said vibrations. These noises are deleted by a band pass filter 15. The center of the filter 15 is tuned to the frequency of vibrations and therefore only the twist vibration component of the shaft 2 is extracted with high efficiency. This extracted vibration component is inputted to a driving circuit 16 for motor 1. Thus the head 6 is moved onto a designated track position according to the track command signal received from a connected computer and at the same time the generation of vibrations is suppressed.
