Title: Method of replacing existing main pipe with novel main pipe
Inventor: NIKI MORITAKA
IPC: E21B7/20
Filed: 1987-06-26
Abstract: PURPOSE: To attempt an exchange of the old tube for a new one without digging up the surface of the earth by exchanging a temporary tube for the new one after attaching a temporary tube to an excavator and advancing the excavator, putting it in the old tube and exchanging the old tube for the temporary one. CONSTITUTION: To the rear end of an excavator 4 having a drum larger in external diameter than an old tube 1, a temporary tube 5 having nearly the same diameter with that of a new tube 9 is attached. The method of exchanging for the temporary tube 5 is to advance the excavator 4 forward in an impactive manner with the leading end entering within the old tube 1, causing the old tube 1 to break, be pushed and spread toward the perimeter. Afterwards, to one end of the temporary tube 5, the new one 9 is connected, the temporary one 5 is pulled from the other end and the temporary one 5 is exchanged for the new one 9. As a result, the exchange can be performed without damaging the coating nor the lining of the inner plane of the new tube. Furthermore, less thrust power means reduction in affecting the surrounding ground unfavorably.

Abstract: PURPOSE:To obtain easily stable zener voltage, by forming a base layer in a portion of the surface section of a semiconductor substrate, and by forming an epitaxial layer with a higher impurity concentration than that of the substrate, on the surface of the substrate. CONSTITUTION:On a semiconductor substrate 21 which includes an N<+> type layer 212 laminated on an N<-> type layer 211, an epitaxial layer 22 is formed which has a lower resistance than that of the layer 211.

A zener voltage value of the transistor uniting the zener diode produced in this way, is determined by the specific resistance of the layer 22. Since the specific resistance of the layer is stable and arranging relation between the layers 22 and 25 is also stable, the zener voltage becomes stable without resulting in unevenness.

Filed: 1989-06-22
Abstract: PURPOSE: To determine specific gravity by generating temp. pulses within the heating element arranged in close vicinity to a fluid to be measured and using the thermal sensor connected to the heating element through the fluid to be measured to measure specific heat and heat conductivity. CONSTITUTION: Elements 122, 124, 126 are set to heating elements and a sensor and thermal insulation is provided between the sensor and the heating elements. A temp. marker is set in the sensor so as to determine the time necessary for generating the corresponding temp. change and, when heat pulses are applied across the heating elements, heat is transmitted to the sensor from the heating elements through a fluid to be measured. Herein, the length of the thermal pulses from a supply source is set to such a degree that the heating elements reach a stable state only during a short period so as to generate both of a stable state and a transient state by the pulses.  Heat conductivity (k) is determined from the flat part of the temp. graph showing the stable state and, next, specific heat cp is obtained on the basis of the heat conductivity (k) and the temp. change ratio in the transient state and both values are combined to calculate specific gravity.
