Abstract: PROBLEM TO BE SOLVED: To prevent infiltration of welding sputter into a slot and a ventilation duct, by providing a though-hole for welding to a bar for fixing a stator iron core piece with the welding, and welding and fixing the stator iron core piece and bar within the through-hole. SOLUTION: Under the condition that a laminated stator iron core piece 1 is clamped with an iron core clamping plate 2, the internal side of a through- hole 4 for welding of a bar 3, stator iron core piece 1 and end part of bar 3 are welded. When the internal side of the through-hole 4 for welding of bar 3 is welded, stator iron core piece 4, bar 3 and iron core piece clamping plate 2, infiltration of welding sputter into a ventilation duct 5 is prevented. Moreover, since welding is conducted within the through-hole 4 for the welding, the stator iron core piece 1 and a ventilation duct 5 are briefly protected with an incombustible cloth to prevent deposition of weld sputtering. As a result, a protection metal tool for preventing the infiltration of weld sputterings into the ventilation duct is no longer required.

Filed: 1987-12-28
Abstract: PURPOSE:To enable a fire extinguisher to be usable for a long time by flowing a principal ingredient to a duct main flow part in a fire extinguisher vessel and charging an auxiliary ingredient to its low pressure part and mixing and discharging both ingredients. CONSTITUTION:A differential pressure means using a Venturi tube 2 is arranged in a fire extinguisher vessel 1, and the principal ingredient is flowed to the main flow part of the Venturi tube 2 of this differential pressure means from a siphon tube 7 hanging in the vessel 1.

Title: Method for measuring thickness of liner of externally lined pipe
Inventor: HYODO SHIGETOSHI
IPC: G01B17/02
Filed: 1994-12-01
Abstract: PURPOSE: To make it possible to measure the thickness of external liner on a pipe even when the linear is similar in material to the pipe, by projecting ultrasonic wave from inside the pipe and detecting reflected wave. CONSTITUTION: A probe 2 is located inside an externally lined pipe 1 in non- contact state. Ultrasonic wave from the probe 2 is projected vertically to the pipe internal surface according to the pulse signals from a transmitter 3. The ultrasonic wave reflects at the surface, boundary between a mother pipe 1a and liner 1b, and back surface of the liner 1b, sequentially. Each reflected wave is measured by the probe 2, transduced into an electric signal, and output to a TG generator 5 through an amplifier 4. The TG generator 5 generates a gate signal to extract a boundary reflection wave exceeding a specified level and calculates the time from the reception of the boundary reflection signal to the reception of back surface reflection wave. A T/A converter 6 converts the time into the thickness of the liner 1b, and outputs the converted signal.  Thus, the device is capable of non-destructively measuring the thickness of a linear similar in material to a pipe.

IPC: H04J3/04
Filed: 1999-11-19
Abstract: PROBLEM TO BE SOLVED: To obtain a multiplexer which has crosstalk suppressed between its inputs and the output slew rate maximized. SOLUTION: A two-input differential multiplexer 10 receives logical level input signals IN1 and NIN1, and IN2 and NIN2 which are complementary to each other. Furthermore, mutually complementary select signals SEL and NSEL are received and the signals IN1 and NIN1 or signals IN2 and NIN2 are led selectively to the output.

Abstract: PURPOSE:To improve the evaporative capability of refrigerant by connecting a refrigerant tube leading out of a gas-liquid separator and an evaporator outlet port to a refrigerant tube with a flow amount regulating valve whose opening degree varies in accordance with dryness detected by a dryness detecting means. CONSTITUTION:A refrigerant gas having a high temperature and a high pressure, which has been compressed by a compressor 1, passes through a refrigerant tube 8 and is condensed and liquefied by a condenser 2.

The inlet pressure of the decompressor is detected by a pressure sensor 14, the inlet temperature of the decompressor by a temperature sensor 16 and the outlet pressure of the decompressor by a pressure sensor 15, respectively. On the basis of these values thus obtained by the sensors, the outlet dryness of the decompressor is calculated by a dryness detecting means 17, and an opening control for a flow amount regulating valve is carried out by a flow amount regulating valve controlling means 18 based on the dryness, whereby only the saturated gas refrigerant is is led out to a refrigerant tube 12. By this method, the evaporative capability of the refrigerant can be improved.
