Title: Device for detecting penetration of pierced hole of laser beam machine
Inventor: MURATA YOSUKE
IPC: B23K26/00
Filed: 1992-02-28
Abstract: PURPOSE:To enable the judgment of penetration with high reliability by judging whether the pierced hole of a work is penetrated or not from an acoustic change detected by an acoustic sensor. CONSTITUTION:The work W is irradiated with the laser beam from an irradiation head 1 to penetrate the pierced hole P in the work. The acoustic sensor 2 is brought into contact with the work W. Whether the pierced hole P of the work W is penetrated or not is judged by a penetration judging means 22 from the acoustic change detected by the acoustic sensor 2. As a result, the processing time is shortened and the processing quality is improved.

IPC: A01C11/02
Filed: 1991-04-12
Abstract: PURPOSE:To simplify speed-change operation, in a transmission for an agricultural machine or the like, by juxtaposing two systems of transmission belts and making one of them to be reversely transmittable, and also by contriving it in such a way that when a movable divided-pulley is brought near to a fixed half pulley on one side, it is drawn apart from a fixed half pulley on the other side. CONSTITUTION:When an operating lever (not shown) is operated to the neutral position, a movable divided-pulley 17 is positioned in the central position between first and second fixed half pulleys 12, 13, and the belt-pressedly-holding distance of the first driving pulley 18 and that of the second driving pulley 23 become wider than the belt width, so that both of the transmission belts 20 and 25 do not transmit power. When the movable divided-pulley 17 is brought near to either of the fixed half pulley 18 or 23, the transmission belt 20 or 25 to which the pulley 17 is brought near is driven, and on the other side, the distance between the movable pulley 17 and the fixed half pulley 13 or 12 becomes wide, so that the transmission belt 25 or 20 is not driven. And a reversing transmission 22 is connected to the system of the second transmission belt 25 to reverse the driving direction.

Title: Fuel injection device and its adjustment method in electronically controlled diesel engine
IPC: F02D41/20
Filed: 1992-04-01
Abstract: PURPOSE:To easily heighten the accuracy of correction to an increased oil transfering factor of an injection pump by previously correcting the discrepancy of both an injection time command value and an injection quantity command value to their respective reference values by means of a first correcting resistance and then finely adjusting the injection quantity command value by means of a second correcting resistance. CONSTITUTION:A first correcting resistance M15 posseses a resistance value to electrically correct an injection time command value calculated by an injection time calculating means M11, so that an interval between a time of output of a reference pulse from a pulser M7 and a time of actual fuel injection coincides with a prescribed reference value. By externally attaching the first correcting resistance M15 to an injection pump M5, an injection time command value can previously be corrected, and at the same time an injection quantity command value calculated by a calculating means M13 can also be corrected in advance. Meanwhile, the resistance value of a second correcting resistance M16 is determined in such a manner that the injection quantity command value, which was already corrected by the first correcting resistance M15, can fine be adjusted in addition. Accordingly, the injection quantity command value is roughly corrected in advance and then is finely corrected again, thereby heightening the accuracy of correction.

Title: Phased locked loop circuit
Inventor: SUZUKI YOUSUKE
IPC: H03L7/10
Filed: 1986-04-07
Abstract: PURPOSE:To seure a phase locked range in a small number of steps by produc ing the control signal based on a sequential comparison method. CONSTITUTION:A frequency comparator 1 compares the frequency of an input signal with that of a VCO 8. A control circuit 12 contains three registers and the 1st and 2nd registers store at first the minimum and maximum values. While the 3rd register stores the calculated medium value of contents between the 1st and 2nd registers. The control data on the VCO 8 is delivered based on the difference between the comparison result of frequencies and the contents of the 3rd register. When the input signal frequency is lower than the output frequency of the VCO 8, the contents of the 1st register are rewritten into those of the 3rd register. Thus the contents of the 1st register are reduced. While the contents of the 2nd register are rewritten to those of the 3rd register if the input signal frequency is higher than the output frequency of the VCO 8. Thus the contents of the 3rd register are increased.
