Title: Fuel injection control for internal-combustion engine
Inventor: FUJITA MASATO
IPC: F02D41/04
Filed: 1984-11-13
Abstract: PURPOSE:To improve the operationability or fuel consumption while to prevent deterioration of emission by setting the completion timing of fuel injection within intake stroke in the rear of top dead center of respective cylinder under acceleration while in front of intake stroke prior to top dead center under non-acceleration. CONSTITUTION:Control circuit 20 will set the completion timing of fuel injection valve 6 within the intake stroke in the rear of top dead center of respective cylinder under acceleration. Consequently, the intake air speed will go to the maximum at the position of intake valve 8 which will open to the maximum at the time point same with the final reaching time of fuel thus to promote secondary atomization of fuel and the intake efficiency and to improve the transient response, operationability or fuel consumption. Under upon-acceleration such as idling, the completion timing of fuel injection is set immediately before the intake stroke prior to the top dead center. Consequently, the fuel to be discharged from an exhaust valve 5 can be reduced to prevent fire, engine vibration, or deterioration of emission.

Title: Coordinate input device
Inventor: KAZAMA MITSUO
IPC: G06F3/03
Filed: 1995-08-24
Abstract: PROBLEM TO BE SOLVED: To provide a coordinate input device of high precision which does not have the problem of a decrease in input speed by previously detecting a rough abutting position of a coordinate indicating means in addition to coordinate input of a table and calculating the accurate coordinates on the basis of the detected position. SOLUTION: When an operator makes the detection electrode 6 at the tip of an input pen 5 abut on a point D on the board surface of the table 1, the rear end of this input pen 5 leaves a point A or B at an end part on a rail 12, so a fixed member 11 is drawn because of the elasticity of a cable 7 to slide on the rail 12 in parallel to a coordinate axis, so that it stops at nearly the same position B on the axis as the abutting position. At this time, the electric signal from a transmission type photointerrupter 13 which is shielded by a shutter plate 14 installed on the fixed member 11 from light is sent out to a CPU 10 to calculate the rough position on the tablet 1 in the CPU 10. A signal for capacitive coupling is applied to only an electrode line 2 nearby the rough position and the CPU 10 computes the abutting position.  Consequently, the coordinate position can be calculated speedily and precisely.

Filed: 1990-09-10
Abstract: PURPOSE:To make the device thin by providing a sliding member freely slidably between a holder and a cover member and making the loading face of a turn table close to a frame. CONSTITUTION:Since a sliding member 14 is provided freely slidably between a holder 5 and a cover member 13, an unused space between the holder 5 and the cover member 13 can be effectively utilized and a space conventionally required for the sliding member 14 between the holder 5 and a frame 2 can be eliminated so that the holder 5 can be arranged at a position much closer to the frame 2.

Title: Amplifier circuit
Inventor: IRIE HIRONORI
IPC: H03F1/34
Filed: 1992-09-08
Abstract: PURPOSE:To enlarge the open gain of the amplifier circuit and to improve the characteristic such as band width or input converting noise by adding a differential amplifier between two amplifying elements in preceding and following steps. CONSTITUTION:The received signal of an optical signal from a photodetector 1 is inputted to the gate of an FET 2 in the first step, amplified by the FET 2, differential amplifier 4 and FET 7 in the following step and outputted from the source of the FET 7. The AC open gain of a negative feedback amplifier circuit is almost decided by the product of a transconductance gm of the FET 2, drain load 2 and voltage gain beta of the differential amplifier 4. Therefore, when the gain beta is enlarged, it is not necessary to enlarge the gm of the FET and the load 3 rather than proper values but the AC open gain can be turned to a sufficient level. On the other hand, since the average value of outputs from the differential amplifier 4 is detected and returned to an inverse phase input, the regular phase input voltage of the amplifier 4 can be made almost equal to the average value of output voltages at all times. Therefore, the characteristic such as band width or input converting noise can be improved.
