Title: Solenoid
Inventor: SUZUKI MIKIO
IPC: H01F7/16
Filed: 1987-03-26
Abstract: PURPOSE:To improve the sucking force of a spool with the aid of a yoke by causing the spool to be composed of a large shaft of an one side part and a small shaft part of the other side part, thereby mounting, in the first yoke, the first engagement hole where a pointed end of the large shaft part is detachable and, in the second yoke, the second engagement hole where the pointed end of the small shaft part is inserted. CONSTITUTION:A spool 5 is composed of a large shaft part 51 where an outer circumferential diameter of its one side end part is large and a small shaft part 52 where the outer circumferential diameter of the other side end part is small. The first yoke 3 comprises the first engagement hole 31 having a large inner circumferential diameter where a pointed end of the large shaft part 51 of the spool is detachable and the second yoke 4 comprises the second engagement hole 42 having a small inner circumferential diameter where the pointed end of the small shaft part 52 of the spool is inserted. Once the first and second yokes 3 and 4 are magnetized by applying a current to a solenoid, the first yoke 3 allows the first engagement hole 31 having the large inner circumferential diameter to generate magnetic force. In response to the above magnetic force, the large shaft part 51 is sucked in the first engagement hold 31 and quickly moves the whole spool body in the direction of sucking by means of the first yoke 3. This approach improves the sucking force of the spool without making the whole body of the solenoid larger or without increasing the winding number of the coil.

Title: Knocking sensing device of internal combustion engine
Inventor: KOKUBO NAOKI
IPC: G01M15/00
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To avoid misjudgement of knocking due to combustion noises in a system to judge occurrence of knocking through sensing of the ion current generated in a combustion chamber. SOLUTION: An ion current sensing signal given from an ion current sensing circuit 24 is fed to a band-pass filter 25, which extracts the signal components belonging to the knocking generating frequency band, followed by a peak hold process made by a peak hold circuit 26, and the peak value is read into a microcomputer 28. When the ignition timing is delayed, the microcomputer 28 judges that it is the noise generation region if the signal peak value read from the peak hold circuit 26 is incremental. In this case, knocking judgement is prohibited, and misjudgement of knocking due to combustion noise is avoided.  If the ignition timing is advanced and the signal peak value is incremental, judgement is passed that it is knocking generation region, and the moderating value of the signal peak value is compared with the knocking judgement value, and the result is used to judge whether knocking exists.
