Title: Control method and controller for timing when multi-cylinder internal combustion engine is started
Inventor: ANAMOTO TAKAYUKI
IPC: F02B61/04
Filed: 1995-07-24
Abstract: PROBLEM TO BE SOLVED: To realize always stable combustion regardless of an operating condition and a starting condition at the time of starting by injecting an injection control quantity in a starting mode calculated for each air cylinder in synchronization with an air cylinder detecting signal, and injecting a predetermined fuel quantity in non- synchronization with the air cylinder detecting signal in relation to the whole air cylinders. SOLUTION: In fuel injection control in a starting mode, a fuel control quantity is calculated by being corrected according to an operating condition parameter against a previously set reference injection quantity. The whole air cylinders are operated in the starting mode, and an injection control quantity in the starting mode, calculated per respective air cylinders #1-#6 is injected in synchronization with an air cylinder detecting signal. Therewith, at a point of time when starting time is detected, a predetermined fuel quantity is immediately injected in non-synchronization with the air cylinder detecting signal in relation to the whole air cylinders #1-#6. Fuel injection time Q0 is calculated as Q0=Q1×C0+Q2 Q1 is a reference injection period at the time of starting, CO is a correction coefficient according to an operating condition, and Q2 is an invalid injection period.  Hereby, stable combustion can be realized regardless of the operating condition and a starting condition at the time of starting.

Filed: 1982-10-27
Abstract: PURPOSE:To attain discrimination made easier in a high speed and to improve S/N, by discriminating the pull-in of synchronism from the output difference of plural narrow band filters. CONSTITUTION:An input signal obtained by applying spread spectrum modulation to an information signal by the PN code and the local reference code of a local reference code generator 7 are applied to a correlation device 1, and its output is applied in parallel with plural BPFs 2.

A square detector 3, an LPF4 and an integrator 5 are connected in series to the BPF2 and when the phase of the PN code and the local reference code get close to each other, the information signal increases any filter output. A level detector 8 detects the maximum value of the output of the integrator 5 and a difference of mean values of other outputs, and when the difference is a prescribed value or over, the synchronism state is detected. A comparator 6 compares an output signal of the detector 8 with a threshold value, its output controls the generator 7 to pull in the synchronism and keep the state.

Title: Method for winding wire or yarn
Inventor: OOMIZU KIYOTOU
IPC: B65H54/28
Filed: 1985-08-28
Abstract: PURPOSE:To prevent generation of winding knurl due o inertia after completion of winding up by emitting a takeup bobbin stop signal when the time difference between from actuation of a position sensor till stopping and from emission of stop signal till stopping has passed and by stopping a traverser and winding-up. CONSTITUTION:When a takeup bobbin 1 attains the regular dimension, a regular dimension signal is emitted, and a timer of a sequencer is put on at the timing of a second position signal being emitted. If the set time on the timer is out after passage of the time t0, a stop signal is given to the drive motive for winding. Because the drive motive and bobbin 1 stop after continued rotation for a period of time t b inertia, the time t0 shall be set on the timer so that the time of bobbin 1 stopping is identical to the point of time when a traverse guide retractive position sensor 14 is actuated after time-up when an operator 12 should has passed a first position sensor 11a. That is, the set time t0 shall be so related to the period of time T from the timer being turned on till the bobbin 1 having stopped, that t0=T-t. At the same time with the bobbin 1 stopping, therefore, the traverse guide 8 will also stop in the position having retracted to a flange 2A, which ensures that no winding knurl is generated on the bobbin 1.
