Title: Agitating device of soil improving machine
Inventor: KATO TAKEYUKI
IPC: E02D3/12
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To increase mixing and agitating efficiency by further crashing a clod crashed roughly by a digging blade in the wet columnar improvement of soil by a soil improving machine. SOLUTION: A reverse rotating blade 7 of which diameter is larger than a digging diameter D and which is rotatable reversely to a digging shaft is supported pivotally on the digging shaft 1 of a soil improving machine between a digging blade 3 and a rotating blade 5 over it. Because the reverse rotating blade 7 is rotated reversely to the digging blade 3 as digging is advanced, the clod crashed roughly by the digging blade 3 is further crashed by the reverse rotating blade 7, and solidification material is mixed uniformly. As a result, mixing and agitating efficiency is increased, work period is shortened, and the shortage of strength of the improved soil due to insufficient agitation can be eliminated.

Title: Combustion state detector for internal combustion engine
Inventor: YOSHINAGA TORU
IPC: F02P5/153
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To achieve an accurate detection of the combustion state of an internal combustion engine and moreover, a lowering of cost by accurately detecting the generation of the amount of combustion ion. SOLUTION: A high voltage application circuit 20 works an ignition plug 10 to perform an igniting operation while applying an AC voltage between a pair of opposed electrodes 11 and 12 of the plug 10 when a specified period passes after the ignition. A current detection resistance 15 detects an ion current varying with the increase or decrease in the amount of combustion ion existing between the opposed electrodes 11 and 12. In an ion current processing circuit 40, a low pass filter 41 removes a charged current component (capacitance component) associated with the application of the AC current from the waveform of the ion current detected to extract the combustion ion current alone.  Within the ion current processing circuit 40, an ECU 44 for detecting fires judges the presence of a fire based on a signal passing through the low pass filter 41 and likewise, an ECU 48 for knocking detection judges the presence of knocking based on a signal passing through the low pass filter 41.

Abstract: PURPOSE: To reduce the impact noise with a simple structure by fitting a ring- shaped muffling corrugated spring made of one sheet to an outer marginal part opposite to a magnet and an armature. CONSTITUTION: When a regular coil 2 is not excited, a yoke 1 and an armature 3 are in the separated condition by a brake spring 5, and a rail 46 is pressed to be in the braked condition by arms 41, 42 through linings 44, 45 with a supporting shaft 43 as a fulcrum. When the exciting current flows in the regular coil 2, the armature 3 is attracted against the brake spring 5 to release the braking. During the attraction, the armature 3 is abutted on the yoke 1 with a large impact. The impact is absorbed by a muffling corrugated spring 6 fitted to an outer marginal part opposite to the yoke 1 of the armature 3 to greatly reduce the impact noise. In the muffling corrugated spring, projecting parts or recessed parts are formed with equal intervals at several thin ring parts of one spring stock, and the muffling effect can be kept for a long time for the repeated action.
