Abstract: Reliability of a scintillator structure is improved. The scintillator structure includes a plurality of cells and a reflective layer covering the plurality of cells. Here, each of the plurality of cells includes a resin and a phosphor, and the resin includes a main agent including bi-7-oxabicyclo[4. 1. 0] heptane and a curing agent. Alternatively, each of the plurality of cells includes a resin and a phosphor, and the resin includes a main agent and a curing agent. The main agent includes: 3,4-epoxy cyclohexyl-methyl-(3,4-epoxy) cyclohexane carboxylate; and 1, 2-epoxy-4-(2-oxiranyl) cyclohexane adduct of 2, 2-bis(hydroxymethyl)-1-butanol.

Abstract: A pressure sensor includes a body, a pressure inlet tube housed in the body and having a pressure inlet opening defined therein for introducing oil pressure, and a pressure sensor unit affixed to a proximal end surface of the pressure inlet tube covering the pressure inlet opening to convert the oil pressure to an electrical signal. An oil flow decelerating structure is disposed to a distal end side of the pressure inlet tube for reducing the flow rate of oil.

Abstract: An acceleration sensor element constitutes a piezoresistance type acceleration sensor in which an acceleration sensor chip including a cantilever structure of mass and beam parts and a piezoresistor formed on the beam part is mounted on a main lead which is slanted for positioning the piezoresistor and the center of gravity of the mass part substantially on the same horizontal plane in a mounted state of the sensor. The element thereby improves the reliability and assures such property as other-axis sensitivity of the sensor at the time of shipment.

Abstract: In an acceleration detector for detecting three-dimensional components of acceleration applied thereto independently with respect to three axes X, Y and Z of an orthogonal coordinate system, a plurality of resistance elements having a piezo resistance effect are formed in a thin-sheet resilient member with an unique arrangement thereof for improving the sensitivity of the detector. Electric resistance of the resistance elements is varied in response to strain of the resistance elements accompanied with an elastic deformation of the resilient member. The resilient member is fixed at its periphery on a frame of the detector. A weight is connected with a center portion of the resilient member such that the elastic deformation is caused when the weight is displaced by receiving acceleration.

Abstract: A coagulation reaction tank comprises a cylindrical tank provided in the central part thereof with a rotary stirring mechanism furnished with stirring vanes and a filtration tank for introducing the liquid from within the cylindrical tank in the form of filtrate and discharging the filtrate out of the cylindrical tank. This coagulation reaction tank is characterized by the fact that the filtration tank provided in the bottom thereof with slits is disposed in the cylindrical tank above the stirring vanes or the cylindrical tank provided in the upper part of the wall thereof with slits and the filtration tank is disposed outside the slits.

Abstract: An I/O relay interface module for mounting a plurality of relays which are adapted to be connected to individual external I/O devices to be controlled or monitored by a central controller. The I/O module comprises a plurality of relay sockets for detachably receiving the relays, respectively, and a terminal section including wire terminals internally connected to the relays through the sockets for connection between the relays and the external devices. An I/O connector is provided on the I/O module for connection with the central controller to receive therefrom control signals for energizing the relays for control of the associated devices or transmit to the central controller monitor signals from the relays as indicative of the operation of the associated devices.

Abstract: A brushless D.C. motor wherein one of projected stator poles positioned to be mutually equally spaced in mechanical angle is made sufficiently smaller than the other as partly cut off at circumferentially expanding pole tooth part, the stator poles being respectively polarized depending on controllably varied direction of direct current to coils on the poles by means of a rotor position detecting Hall element which detects the polarity at a predetermined position of the rotor, for allowing the rotor to self-start constantly in one direction with a remarkably increased starting torque.
