摘要： The disclosed rotary encoder includes contact substrate 31 and movable contact plate 32. Substrate 31 contains three fan-shaped conductive layers 34A, 34B, and 34C on positions having a same distance from the center of substrate 31. On the other hand, movable contact plate 32 retains three elastic contacts 36A, 36B, 36C, and rotates. The three contacts have continuity with each other and disposed at positions with a same distance from the center of substrate 31, spaced at a radial angle of 120°. When contact plate 32 is rotated, any two out of three elastic contacts 36A, 36B, and 36C consecutively contact with any two out of three conductive layers 34A, 34B, and 34C. Through the continuity, an electric signal is led out from terminals 35A, 35B, and 35C.

摘要： A package is mainly formed of a package body having a storage area for storing a pressure sensor, a capacity type pressure sensor stored in the storage area of the package body, a lid seals the package body in which the pressure sensor is stored, an adhesive agent for fixing the pressure sensor to the package body, and a bonding wire for electrically coupling a bonding pad of the pressure sensor and a conductive portion of the package body. An adhesive area of the package body and the pressure sensor is set to the area other than a projection area of the diaphragm of the pressure sensor on a mount bottom surface. This makes it possible to provide the package for the pressure sensor capable of detecting the pressure with high sensitivity although the gap between the substrate and the diaphragm has the value with the magnitude of several μms.

A flange (26) is detachably fitted to the top surface of a tank to hold the electric motor (44) in the tank. A downwardly-extending pipe (28) is at an upper end fixed to the flange and at a lower end connected through a terminal box (30) to the electric motor (44). A centrifugal pump (67) is fixed to the underside of the electric motor (44) to have its rotary shaft connected to the output shaft (60) of the electric motor (44). A motor cover accommodates therein the electric motor and the terminal box (30) in a watertight manner. A protective pipe (71) extends from the flange (26) to the motor cover (69) and accommodates therein the downwardly-extending pipe (28) in a watertight manner. A cooling oil is circulated through the motor-cooling oil passage (54) to cool the electric motor. This water-immersed cargo handling pump is suitable for transferring the liquid in a tank of a vessel.

摘要： A pressure sensor includes a gold-silicon eutectic crystal layer interposed between the contact layer and the silicon substrate. Because the contact layer and the silicon substrate are electrically connected to each other by using a gold-silicon eutectic reaction at the time of bonding the silicon substrate and the glass substrate, a contact resistance between the contact layer and the silicon substrate can be stabilized, and a Q value of the sensor can be stabilized. In addition, since the contact layer and the silicon substrate are bonded to each other by the gold-silicon eutectic reaction, the bonding strength is sufficient.
