Title: Temperature detecting circuit
Inventor: NAGAI KENTARO
IPC: H03F1/52
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To detect temperature with high precision even if a reference voltage source does not have high precision, to decrease the circuit scale, and to lower the cost of the circuit. SOLUTION: A constant current is made to flow from a constant current source 12 to an (N+M)-diode series-connection circuit and then a constant current is made to flow to an N-diode series-connection circuit, so that voltages VT1 and VT2 are developed at respective terminals. Those voltages VT1 and VT2 have different temperature-voltage characteristics and the temperature of VT1=VT2 corresponds to detected voltage. When VT1=VT2, the output of a comparing circuit 14 which compares both the voltages is inverted, the mentioned temperature is detected, and a protecting circuit 15 stops the power supply.  Even if the diodes have variance, the temperature-voltage characteristics of the series-connection circuits vary in the same direction and the voltages which vary in the directions are compared relatively, so high-precision temperature detection can be performed without a high-precision reference voltage source and the circuit scale may be small low cost because no reference voltage source is incorporated.

IPC: H02P7/292
Filed: 1986-03-08
Abstract: PURPOSE:To perform purging control without causing the overrunning of a screw by a method wherein the forward and backward shiftings of the screw are performed without applying torque limiting when the purging action is detected. CONSTITUTION:When a positioning command (a) consisting of a pulse train representing the movement per unit time is inputted to a digital-to-analog converter (D/A converter) as the driving command of a servo motor M, the D/A converter 4 converts the differential between said positioning command (a) and the movement (b) of the servo motor M, which is detected with a detector P such as a pulse encoder or the like, into voltage in analog form as a speed command value (c). Concretely, when the difference between the positioning command (a) and the movement (b) of the servo motor M detected by the detector P is large, a speed command value (c), the magnitude of which is large, is outputted, and when the difference just mentioned above is small or the positioning command (a) and the movement (b) become nearly equal to each other, a speed command value, the magnitude of which is small, is outputted from the D/A converter.

Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To prevent release and deposition of preprinting ink by providing a plate surface dry preventing means for preventing drying of a plate cylinder surface after ink is scraped by a doctor, thereby suppressing an increase of adhesive force of postprinting ink. SOLUTION: A printing unit 3 has a cover 13 fixed to a doctor unit 11. This cover 13 is extended to a position having no difficult of conveying a printing sheet 6 wound on an impression cylinder 12 toward the cylinder 12, and a substantially sealed space is formed by the cover 13, doctor unit 11, plate cylinder 10 and cylinder 12 wound with the sheet 6. With this constitution, evaporation of solvent contained in an ink film scraped down by the unit 11 can be suppressed by the cover 13. Thus, the ink film of the non-printing element in which the evaporation of the solvent is suppressed is not increased in its adhesive force, and hence preprinted ink of the sheet 6 is not released. And, it is not transferred as dirt to the sheet 6 by pressing force of the cylinder 12.

Title: Temperature limiter
Inventor: ISHIKAWA TOSHIHIRO
IPC: H01H37/76
Filed: 1988-03-04
Abstract: PURPOSE:To automatically reset a temperature limiter when an environmental temperature is returned to a normal state after a circuit current is limited by connecting a superconducting material having a critical temperature substantially equal to a specified limiting temperature between electrodes. CONSTITUTION:A current limiting element 12 having a superconducting material connected between electrodes 1 and 2 is electrically connected between the electrodes 1 and 2, and the critical temperature of the material is so set as to be substantially equal to a specified limiting temperature, i.e., the upper limit of an allowable environmental temperature. Accordingly, when the environmental temperature becomes higher than the critical temperature of the material of the element 12, the material is converted from a superconducting state to a normal conducting state to stop or interrupt a current. When the generation of heat is then reduced so as to be lower than the specified limiting temperature, the material becomes lower than the critical temperature to become the superconducting state. As a result, it becomes a normal state. Thus, the automatic resetting after the current is limited is performed.

Title: Fuel injection quantity control for internal combustion engine
Inventor: OGATA MASAMI
IPC: F02D41/04
Filed: 1986-03-07
Abstract: PURPOSE:To suppress the overrich or overlean state of the air-fuel ratio in a combustion chamber by varying the quantity of increase/decrease of the fuel injection quantity in transient state as the intake temperature varies. CONSTITUTION:The fuel corresponding to the engine load is jetted from a fuel injection valve 7 in the ordinary operation state. In the transient state where the variation rate of the pressure in an intake pipe which is detected by an intake pipe pressure sensor 11 becomes over a prescribed value, the fuel injection quantity is corrected so that the increase/decrease quantity of the fuel injection quantity varies as the intake temperature detected by an intake temperature sensor 15 varies. Therefore, when the intake temperature is high, in other words, when the fuel atomization sate is good and the quantity of the fuel adhering onto the wall surface is little, the quantity of increase/decrease of the fuel injection quantity is reduced, and when the intake temperature is low, in other words, when the fuel atomization state is inferior and the quantity of fuel adhering onto the wall surface is much, the quantity of increase/ decrease of the fuel injection quantity is increased. Therefore, the air-fuel ratio of the mixed gas supplied into a combustion chamber 27 in transient state is made nearly constant.

Filed: 1986-03-10
Abstract: PURPOSE:To easily know the contents of working by providing a numerical controller with a graphic means for indicating the shape of an object to be worked and the moving course of a tool for the object to be worked based on a command from a CPU. CONSTITUTION:The tool moving information of X, Z and C axes are inputted from a data input means 2 to a CPU 1. When movement is generated in the X and Z axes directions, a course 100 between the moving start point and end point on a side display means. When the tool is moved in the C axis direction, a circular arc formed around the original point O of the X and Y coordinates starting from the current point 101 is displayed on a front display means. At that time, the relative position between the tool 6 and the object 15 to be worked is displayed without rotating the object 15 to be worked. When the axis C is rotated by an angle theta to change the position of the tool 6 for the object 15 to be worked for instance, the tool course 8 is drawn as if the tool 6 is rotated to simplify the processing. Thus, the formation of the graphic display means makes it possible to easily and recognizably display the tool moving course of a working machine having a rotary shaft and easily recognize the state of working.
