Title: Idle speed controller for internal combustion engine
Inventor: TAKAGI NOBORU
IPC: F02D41/06
Filed: 1996-07-01
Abstract: PROBLEM TO BE SOLVED: To stably control the number of revolutions of an internal combustion engine at its starting with an idle speed controller for an internal combustion engine. SOLUTION: ISC is fully closed after the starter is actuated until the intake pressure PM drops to a predetermined value PM1, and is thereafter opened to a target opening angle DOP upon the drop of PM to PM1. PM1 is set larger than a target intake pressure PMc corresponding to a target engine speed NEc allowing for time lag in the reflection of the ISC opening angle to the running conditions of the engine. The engine speed NE is thus stably increased to the target engine speed NEc without causing any undershoot or overshoot.

Abstract: PURPOSE:To make it possible to detect errors in a pattern due to erroneous operation and the like, by providing a circuit memorizing the number of shots required for pattern scribing, a blanking counter, and a beam detection counter, and comparing the contents of the circuits one another at the appropriate time. CONSTITUTION:The ON and OFF operation and the deflection of the electron beam are controlled by a digital control circuit 11 based on the pattern data and the control signal from a CPU10. For example, in a formed beam system, the number of divisions of the pattern is computed and sent to a shot number memory circuit 12. Pulses are sent to the blanking counter 14 every time the blanking signal is generated from a driving circuit 16. The pulses are sent to the beam detection counter 15 through a detector 25 and a circuit 17 every time the detected signal of the beam which has arrived at a exposing specimen 26, exceeds a specified level, and the pulses are counted. The contents of the circuits 12, 14, and 15 are inputted in a comparator 13 which is provided in the circuit 11, every time the scribing of the arbitrary unit of the pattern data has completed. The erroneous operation or abnormality in the circuit systems and the electrooptical systems can be detected based on the agreement or disagreement in the comparison, and the pattern error can be confirmed.

Title: Analog-digital converter
Inventor: KATOU MASAAKI
IPC: H03M1/14
Filed: 1979-12-27
Abstract: PURPOSE:To reduce the time of conversion of an analog-digital converter, by switching the variable current source immediately after the end of the first operation of a comparator. CONSTITUTION:When the sample-held input analog voltage is applied to the input terminal 1, the register 6 is reset by the control of the timing circuit 8. Thus the output of the D/A converter 7 is set to zero, and at the same time the current value of the variable current source 4 is set to 10. Then the latch enable signal is applied to the comparators 2-1-2-7 from the timing circuit 8 to carry out a comparison, and the A/D conversion output of higher 3 bits is stored in the register 6. The current value of the source 4 is switched by the control of the circuit 8 as soon as the above- mendioned comparison ends with the comparators 2-1-2-7. In parallel to this switching action, the output of the register 6 is converted into the analog voltage through the converter 7 to be used as a new standard voltage. After this, the A/D conversion of the lower 3 bits is carried out in the same way.

Filed: 1983-09-17
Abstract: PURPOSE:To decrease the transmission time of a phase pulse synchronizing signal by injecting a phase pulse synchronizing signal to all channels at the synchronizing mode and averaging a subtracted value between the channels. CONSTITUTION:The same phase pulse synchronizing signal 9 as the phase pulse signal is injected to all the channels CH1-CH10 at the signal cycle 3 and no phase pulse synchronizing signal 9 is injected at the noise detection cycle 4. The reception side separates a reception waveform 12 of the phase pulse synchronizing signal including noises from an ANC voltage wave of the reception cycle 3 and stores a digital value D3 in a memory. A noise waveform 16 is detected at the noise detection cycle 4, the waveform is converted into a digital value D4 and stored in the memory. Then the D4 is subtracted from the digital value D3 and the subtracted value is subjected to arithmetic average among the channels CH1-CH10. The result is stored for a prescribed number of times, the preceding average value is compared, and when the average value is decreased less han the preceding average value, it is descriminated that the synchronism is finished.

Filed: 1996-07-02
Abstract: PROBLEM TO BE SOLVED: To safely and efficiently carry a wheel set having a speed reducer by arranging a freely ascending-descending and advancing-retreating wheel set carrying arm and a rotation stopping tool to check rotation of the speed reducer on a self-traveling bogie. SOLUTION: This wheel set carrying robot for rolling stock 1 is composed of a self-traveling bogie 2, a wheel set carrying arm 3 and a rotation stopping tool 4. The self-traveling bogie 2 travels in an unmanned condition by a magnetic induction system. When a wheel set 50 to which a speed reducer 51 is attached is raised, a bogie main body 2a is retreated in a condition where the wheel set carrying arm 3 is lowered to the lowest position, a carrying part 38 is positioned just under a wheel shaft. Next, after the wheel shaft is carried by the carrying part 38 by raising the wheel set carrying arm 3, the rotation stopping tool 4 is rotated, and a flange part of the speed reducer 51 is pressed down. Therefore, even if the wheel set carrying arm 3 is raised, since rotation of the speed reducer 51 can be prevented, the wheel set 50 can be safely and efficiently carried.
