Filed: 1994-03-08
Abstract: PURPOSE:To prevent lock arm damage by providing a flexible lock release operation wall provided with a lock engagement release surface engaged with the side part on the free end side of a lock arm. CONSTITUTION:When a male connector 23 is inserted into an engaging hood 25, a lock arm 31 runs over a locking wall 51, and the type connector 23 is fitted to a female connector 27. In order to remove the male connector from the female connector 27, a pair of lock release operation walls 39 are pinched and deformed in a direction for approaching each other. When a pair of lock release walls 39 are deformed, the engaging piece part 37 of a lock arm 33 slides on a lock engagement release surface 43 and is guided downward. When the engaging piece part 37 is guided downward, the locking piece 37 is fitted in an engagement groove 45, and the lower surface side of the engaging piece part 37 comes into contact with a contact part 47. At this time, the lock arm 33 is deformed, and the engaged status of a locking protrusion 49 with a locking wall 51 is released.

Title: Differential pressure transmitting apparatus
Inventor: SAI YUKIO
IPC: G01F25/00
Filed: 1990-02-20
Abstract: PURPOSE:To perform remote manipulation by providing an electromagnetic three-way valve for guiding the target pressure difference and a differential pressure transmitter which converts the introduced pressure difference to a current signal and transmits to a transmission line. CONSTITUTION:A differential pressure transmitter 360 converts the pressure difference introduced through a three-way valve 320 to an electric signal. The output from the transmitter 360 is compensated based on a zero point compensation data set beforehand by a microcomputer 364. At the same time, the detecting value after the compensation is converted to a current and sent to a transmission line 4. A coil 327 of the electromagnetic three-way valve 320 is inserted in series to the transmission line 4. Terminals of the coil 327 of the electromagnetic three-way valve 320 can be shortcircuited by a switch 367 controlled by the microcomputer 364. Therefore, when the switch 367 is in the ON state (in the measuring state of the differential pressure), power supply to the coil 327 is not carried out. When the switch 367 is in the OFF state (in the zero point adjusting state), the coil 327 is made conductive.

Abstract: PURPOSE: To restrict exhaust noxious composition effectively by communicating a burnt-gas-filled small chamber to a cylinder port to which a fresh air supply pipe opens.  
     CONSTITUTION: A small chamber 4 to whcih a fresh air supply pipe 5 is opened by a check valve 4 is communicated with a tangent cylinder port 3 which opens near the bottom dead center of a piston 2 in a cylinder 1. As suction stroke comes near to the end, the cylinder port 3 opens by operating the valve of the piston 2 so that burnt gas having been stored in the small chamber 4 in the preceding stroke is injected into the cylinder 1 and fresh air supplied from the external air supply through a supply pipe 5 flows into the cylinder 1 through the small chamber 4. Burnt gas is blasted to reduce NOx and fresh air is supplied to supercharge. Both functions, blasting and supply, can reduce noxious exhaust composition effectively and maintain or improve the output performance.

Abstract: PURPOSE:To prevent the deformation of a cross sectional shape affected by an orientation magnetic field and the generation of warp, etc., caused by the difference of cooling velocity by charging a hollow tubular resin film-made tube body with a resin magnet raw material by pressure. CONSTITUTION:A contracted hollow tubular resin film-made tube body 3 whose tip is sealed is mounted on a tip of a nozzle 2 of an extruder 1. A resin magnet raw material wherein resin becoming granule or liquid at a room temperature is selected as a binder is extruded from the nozzle 2, and the resin magnet raw material is put by pressure inside the tube body 3 while elongating the tube body 3. While a base end of the pressure-charged resin film-made tube body 3 is sealed and separated from the nozzle 2, an independent unit charger 4 is formed by sealing by choking one or more intermediate positions. Thereby, a cross sectional shape is not deformed even if an orientation magnetic field is applied to a semi-hardened resin magnet raw material.

IPC: F04C29/04
Filed: 1987-02-23
Abstract: PURPOSE:To keep an oil level so properly as well as to improve the capacity and reliability of a compressor, by installing a means which is situated in the lower part of a motor rotor and puts a part of oil at the under part of a hermetically sealed vessel back to discharge pipe gas passage of high pressure part. CONSTITUTION:A part of oil 22 collected in a chamber lower part gradually flows to the outside of a compressor with slight differential pressure via the exhaust pipe 50 connected to the downstream side 51 of a discharge pipe 19. And, at the lower part of a motor rotor part 3f, an oil level 22a of a bottom chamber is regulated at a position of an oil outflow port 50a of the exhaust pipe 50 installed on a coil end outer circumferential part. Therefore, an oil stirring loss by the rotor part 3f at the time of low pressure ratio operation is eliminated whereby compressor capacity is largely improved, and at the time of high pressure ratio operation, cooling of motor winding is promotable, and since each of these discharge pipes 10 and 50 leading from both upper and lower spaces in a motor chamber are installed, a pressure loss at the discharge side is checkable to the utmost. Owing to these advantages, the capacity and reliability of the compressor are largely improvable.

Abstract: PURPOSE:To suppress magnetic noise to a necessary level and to perform an eddy current test by using a material of a core in which the ratio of saturated magnetic flux densities of the magnetic core of electromagnet to a tube is equal to or larger than the ratio of sectional area of the tube to minimum sectional area of the core. CONSTITUTION:A magnetic flux PHIs necessary to magnetically saturate the object heat transfer tube 40 satisfys PHIs = (saturated magnetic flux density Bsc of a magnetic core 20) X (sectional are Sc of the core 20) >= (saturated magnetic flux density Bst of the material of the tube 40) X (sectional area St of the tube 40). In order to increase a value of (BscXSc), the area Sc is restricted, and the tube 40 having large St of the above formula, i,e., large sectional area can be applied by the use of the core material having large Bsc. A function for increasing the thickness of the tube 40 to be applied from t1 to t2 is obtained by the use of the core 20 having (the density Bst of the material of the density Bsc of the core 20) > (the density Bst of the material of the tube 40), and hence the test of the tube 40 which has not been able to be tested, can be executed.

Title: Steam leakage detector
Inventor: NAKAJIMA TOSHIRO
IPC: G01N21/17
Filed: 1986-02-25
Abstract: PURPOSE:To detect a steam leakage accurately, by a method wherein steam is irradiated with laser light and the scattered light is branched in two direction to be converted to light with the directions of polarization perpendicular to each other so that the scattered light from the steam is separated from the one from a surrounding wall. CONSTITUTION:Steam leaked from a pipe is irradiated with laser light and scattered light from the steam and the scattered light from a surrounding wall are received with a light receiving section 30. Light passing through a lens 30a at the light receiving section 30 is branched in two directions with a half mirror 30b. One of the lights is made to pass through an analyzer 30c to form an image on an image sensing element 30e while the other is made to pass through an analyzer 30d to form an image on an image sensing element 30f. The analyzer 30c herein used shall be parallel with an irradiation laser light about the direction of polarization while the analyzer 30d shall be perpendicular to the analyzer 30c about the direction of polarization. The scattered light from the steam passes through the analyzer 30c alone while the scattered light from the wall passes through both the analyzers 30c and 30d. Then, the signals from the image sensing elements 30e and 30f are judged 40d. Thus, the conversion of the scattered lights into lights with the direction of polarization perpendicular to each other enabled accurate judgement of steam leakage.
