Title: Knocking control method of engine
Inventor: ANZAI KATSUSHI
IPC: F02P5/15
Filed: 1984-02-01
Abstract: PURPOSE:To aim at improvements in engine output and fuel consumption, by preventing the occurrence of such phenomena that a variation in a background fails to follow up a variation in a load state and ignition timing transiently comes into a state of over-lag timing advance at a time when an engine shifts from a light load state to a high load one. CONSTITUTION:When a knock controlling interruption routine is set in motion by a control circuit, cylinder discrimination takes place with a signal out of a cylinder discrimination sensor, reading out a background level, and peak output of a peak hold circuit is taken therein, thus whether knocking occurs or not is judged. In the light-load state that a judging result of yes or no for knocking occurrence does not reflect to the ignition timing, even when a fact that ''there is knocking'' is judged, the peak output of the peak hold circuit this time of the detection signal of a knock sensor is calculated for a mean value with the background level whereby a variation in the background level is made so as to follow up a variation in engine laod.

Title: Dehydrating method for anaerobic digestion sludge
Inventor: OYAMA AKIO
IPC: C02F11/00
Filed: 1995-02-06
Abstract: PURPOSE: To efficiently perform dehydration by improving dehydrating property of anaerobic digestion sludge of sewage. CONSTITUTION: After aeration is performed for anaerobic digestion sludge, excess sludge is mixed therewith. Metallic salt is added to the obtained mixed sludge and then an amphoteric organic polymer flocculant is added and aggregation treatment is performed and aggregated sludge is dehydrated by a dehydrator. Anaerobic digestion sludge is aerated to degass carbonic acid gas dissolved in sludge. Thereby, when metallic salt is added in the post-process, aggregation is prevented from being hindered by generation of carbon dioxide gas from sludge. Since alkalinity of anaerobic digestion sludge is high and aggregation properties are bad, excess sludge having low alkalinity is mixed and alkalinity is lowered and aggregation properties are raised.  After aggregation properties are improved by aeration and mixing of excess sludge, metallic salt is added and the neutralization of charge is performed. Then, effective aggregation and condensation are performed by adding the amphoteric organic polymer flocculant. Dehydrating properties of the obtained condensed sludge are extremely good and dehydration is performed at high filtration velocity and dehydrated cake having low water content is obtained.

Title: Method and device for providing sound pitch mark
Inventor: KOYAMA TAKAO
IPC: G10L25/90
Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To prevent quality deterioration in pitch control of synthetic sound and in speed control of sound generation. SOLUTION: A temporary pitch-mark extracting part 201 finds negative-to- positive zero-crossing points as temporary pitch mark positions, which occur on a time-series basis immediately before respective local peak positions, based on given local peak positions and digital data of input sound. The temporary pitch mark positions are outputted, together with the local peak positions and digital data, to a pitch-mark search zone setting part 202. With regard to the temporary pitch mark positions, the setting part 202 computes the amount of movement from the respective local peak positions to the temporary pitch mark positions. It determines a pitch-mark position search zones to be searched by a pitch-mark searching part 203. The search zones and the digital data are outputted to the searching part 203.  The searching part 203 searches for a pitch mark position, that is a negative-to-positive zero-crossing point nearest to the center position of the search zone. If no zero-crossing point is found, the center position is taken as the pitch mark position. Such searching is performed on all the local peak positions. The pitch mark positions thus found are outputted to a pitch-mark position verifying part 204.

Title: Paper sheet accumulating device
Inventor: SASAKI SHIGERU
IPC: B65H29/40
Filed: 1985-02-04
Abstract: PURPOSE:To cause an impeller to be prevented from making contact with accumulated paper sheets through rotation of the guide receiving plates of the impeller, by a method wherein, when the feed of the paper sheets is stopped during rotation of the receiving guiding means of the impeller, a push plate is lowered through detection of said stop of the feed. CONSTITUTION:Paper sheets e.g., bank notes, from a conveyance passage 28 are guided and gradually accumulated on a push plate 34 through rotation of an impeller 20. An amount of the paper sheets accumulated is detected by a first sensor 31, and a control circuit 37 lowers the press plate 34 through the running of a driving motor 38 so that a press pressure is adjusted to a given value. In case no bank notes are conveyed even after a specified time lapsed, a third sensor 33 detects said fact, and the control circuit 37 runs the driving motor 38 to lower the press plate 34. Along with said lowering, an arm 23 is engaged with a stopper 35, and a second sensor 32 is turned OFf to stop lowering of the press plate 34. This causes the impeller 20 under rotation to be prevented from making contact with the accumulated bank notes, resulting in prevention of the occurrence of charging due to generation of statistic electricity and prevention of drawing in of the paper sheets by means of the impeller, and improvement of accumulating performance.
