Title: Mtf measuring system for optical reader
Inventor: NOGUCHI AKIHIRO
IPC: G06K7/10
Filed: 1981-12-19
Abstract: PURPOSE:To obtain easily and surely MTF in the subscanning direction, by storing only a picture signal corresponding to a line pattern in a waveform storing circuit in the optical reader which reads line patterns. CONSTITUTION:A picture signal is sampled after a required time from the start time of main scanning A, and detected data is stored in a memory 8. This operation is repeated for every scanning; and when the number of times of scanning reaches a prescribed value, the data waveform stored in the memory 8 is reproduced, and this waveform becomes a waveform obtained by reading a sampling line 5 in the subscanning direction B, and thus, MTF is calculated easily.

Patent JP-H0488513-A (JP)
Title: Constant voltage circuit
Inventor: HARA MASAYA
IPC: G05F1/56
Filed: 1990-07-31
Abstract: PURPOSE:To output a voltage almost same as a source voltage by setting a parallel-connected PNP transistor in a saturated state when a constant voltage diode is de-energized. CONSTITUTION:When the voltage VB of a power source 2 is less than the voltage VZ1 between the cathode and anode of the constant voltage diode 3 when it is energized and the constant voltage diode 3 is deenergized, no current flows on the base of an NPN transistor 6, setting a cutoff state. Thereby, the current flows on the base of an NPN transistor 7 via a resistor 8, setting the saturated state, and the current flows from the base of the PNP transistor 9 to the collector of the NPN transistor 7 via a resistor 10, which sets the PNP transistor 9 at the saturated state. Therefore, assuming the saturation voltage between the collector and emitter of the PNP transistor 9 as VCEsat9, a load voltage V0 can be expressed in the following equation; Vo=VB-VCEsat9.

Title: Fuel injection valve
Inventor: TORITSUKA KEIJI
IPC: F02M61/10
Filed: 1984-10-01
Abstract: PURPOSE:To prevent fuel from solidifying, by providing an opening and closing valve, opened and closed by the internal pressure, in a return oil path connected with an oil reservoir chamber in a fuel injection valve, in the case of a marine engine using oil of low quality. CONSTITUTION:Fuel from a furl injection pump is forced to be fed by pressure into an oil reservoir chamber 5 via a feed oil path 1, and the fuel, in its pressure increases to a valve opening level or more, is injected from a jet hole 13 by lifting a nozzle needle 6 against a spring 11, but the pressure of fuel is applied to a pressure receiving surface 17a of an opening and closing valve 17 via a return oil path 15, closing it against a spring 17c. And if the pressure in the feed oil path 15 decreases to a considerably low level when an engine is stopped, the opening and closing valve 17, being opened by the return spring 17c and opening the return oil path 515, allows fuel in a low pressure from an injection pipe connected with the feed oil path 1 to flow via the oil reservoir chamber 5, return oil path 15 and an overflow connection pot 16. Accordingly, the fuel, never standing still in a fuel injection valve, is prevented from solidifying.

Title: Engine control device
Inventor: UCHIUMI KAZUHIRO
IPC: F02D41/00
Filed: 1986-09-03
Abstract: PURPOSE:To carry out fuel injection control with one kind of a reference position sensor for a low-voltage electronic distribution device, by outputting a fuel injection start pulse after reaching a fixed angle of an engine rotation from a rise timing of a reference position signal, and then supplying this pulse to the next cylinder after a fixed angle. CONSTITUTION:A reference position signal 1a is output from a reference position sensor 1 for detecting a first cylinder and so on every other cylinder, and a rotation signal 2a is output from an angle sensor 2 for detecting an engine rotation angle. The reference position signal 1a and the rotation signal 2a are input into a cylinder determining device 3 which in turn outputs a reference cylinder signal 3a. At this time, a computing device 5 determines the present cylinder to be a reference cylinder by an interruption signal generated at a fixed rotation angle. Then, the computing device 5 sets in an I/O device 6 a next cylinder for injection, a fuel injection time, a fuel injection start angle and a next rotation angle for a next interruption signal. When a count value of an angle counter comes into coincidence with the fuel injection start angle, a fuel injection pulse is output to the next cylinder for injection for the fuel injection time. Therefore, fuel injection control for each cylinder may be carried out only by one kind of the reference position sensor.

IPC: G05D17/02
Filed: 1988-08-19
Abstract: PURPOSE:To reduce the exciting torque with high accuracy without performing a high-speed arithmetic process by reading a load waveform out of a torque waveform memory part in accordance with the operating state of a motor-driven machine and controlling the electromagnetic torque produced by an motor-driven element. CONSTITUTION:The operating state of a compression element 15 of a motor- driven machine which is revolved by an motor-driven element 14 is detected by the pressure pickups 20 and 21 and supplied to a microcomputer 26 via the A/D converters 29 and 30. At the same time, the rotational angle of a rotary spindle is detected via the electromagnetic pickups 18 and 19 and supplied to the microcomputer 26. Then the microcomputer 26 reads the torque waveform of the element 15 for each rotational angle corresponding to the operating state out of a ROM 31 via a CPU 28. A base driver 33 of a torque controller controls the electromagnetic torque so that the torque waveform of the element 14 is coincident with the reading torque waveform. In such a constitution, it is not required to perform a high-speed arithmetic process from the residual torque. Then the exciting torque can be reduced with high accuracy in simple constitution.

Abstract: PURPOSE:To eliminate the need of a large power generating equipment by producing flowing energy due to a difference between the specific gravity of water and that of carbonic acid gas exhaled from human body during diving, producing compressed air by using the flowing energy and sending breathing air to the human body from the compressed air. CONSTITUTION:Carbonic acid gas which is exhaled from the human body during diving and a low specific gravity is discharged into an exhaust pipe 10. A valve which provides communication between the inside and the outside of the pipe 10 is opened due to a difference between specific gravity of the inside gas and that of the outside water, so that water flows into the pipe 10. carbonic acid gas inside the pipe 10 is thereby forced upwards and the resultant flowing energy of the carbonic gas turns a hydraulic turbine 12. The turning force of the hydraulic turbine 12 is boosted by the actions of power transmitting gears 14 and 15 and then transmitted to a crank mechanism 16. Once the crank mechanism 16 is driven, compressed air is generated by an element 5c and accumulated in an air tank 7b. Of the compressed air in this tank 7b, the quantity of compressed air demanded by the human body is sent to the human body via an air pipe 8.
