Title: Positive charging pulse sending circuit
Inventor: SHIMOMA MASASHI
IPC: H04M15/00
Filed: 1987-10-26
Abstract: PURPOSE:To reduce charging noise with a simple circuit by using a capacitor and a resistor so as to smooth a charging pulse transmission control signal and using 1st and 2nd transistors(TRs) so as to send a smooth positive charging pulse. CONSTITUTION:With a voltage of a charging pulse sending control signal inputted to an input terminal 28 going to a ground (earth) level, a base voltage of the 1st TR 23 is decreased by a time constant depending on the capacitor 25 and resistors 26, 27. When the base voltage is lower than the base voltage of the 2nd TR 21, the 2nd TR 21 is turned on and the 1st TR 23 is turned off. In selecting the change in the base potential of the TR as nearly 0.6V, the collector current of the 2nd TR 21 changes smoothly both for leading and trailing states. In this case, in selecting resistors 17, 18 of the final stage properly for the constant current circuit, the base current waveform is the collector current waveform of the final stage as it is and the collector current of the waveform is outputted to a charging pulse output terminal 11.

IPC: B66C13/00
Filed: 1995-10-18
Abstract: PROBLEM TO BE SOLVED: To display any information of failure and trouble comprehensibly by photographing the lower part of a boom tip part by a telecamera, recognizing the operating state upon obtaining information from the measuring instruments and sensors of a crane, and also recognizing the occurrence of trouble with a trouble diagnostic algorismic system, thereby forming an informative report centering on a character, and combining it together with an image. SOLUTION: A lower part of a boom tip part is photographed by a telecamera 9 attached to a boom, projecting it on a monitor television 11. A computer 13 executes a trouble diagnostic process in accordance with any state information obtained out of measuring instruments and sensors containing those of operating, controlling and driving systems of a crane, and in the case where the occurrence of trouble is recognized, this trouble state is formed into trouble information centering on a character. The algorism of a trouble diagnostic process is based on a data base analyzed in the causal relation of trouble in the past. Image data centering on the character line edited with the trouble information is fed to a superimposer 10, and it is superimposed on the image taken by the telecamera 9, displaying this character-centered image.  With this, the inducing factor of any operational mistake is well reduced.

Title: Production of hollow tube
Inventor: OGATA KAZUYA
IPC: C08J5/12
Filed: 1993-10-01
Abstract: PURPOSE:To continuously produce standard-length heat-shrinkable tubes. CONSTITUTION:A continuous hollow tube T1 expanded to approximately a circular form by a pressurizing force applied inside is passed through between a pair of pressure rolls 1, 1, thereby being run while being squeezed. A squeezed continuous flat tube T2 running is passed through between at least one pair of separated molding rolls 4, 4-6, 6, whereby a pressing force is applied to the periphery of the continuous flat tube T2 to recover the continuous flat tube T2 to approximately a circular form. After that, the tube is cut in lengths for obtaining hollow tubes T4. In this production method, a hollow tube of approximately a circular form can be obtained. Furthermore, since folded lines produced when the tube is squeezed flat or recovered in the process are extended in the longitudinal direction of the tube as a kind of reinforcing part, the hollow tube has a strong nerve.

Atmospheric temperature data are inputted into the processor 4. The temperature difference between the maximum temperature of the surface of the pile 6 and the atmospheric temperature is obtained until the specified period with the processor 4. The internal maximum temperature in the pile 6 is predicted and operated based on the temperature difference. The time point when the internal maximum temperature in the pile 6 reaches a specified temperature is obtained based on the surface temperature when the deposition is started and the elapsed time until the time when the internal maximum temperature is predicted. A time until the pile 6 is spontaneously fried is added to said time point. Thus the firing time is predicted. In this way the time of the spontaneous firing can be accurately predicted.
