Abstract: An ultrasound apparatus of a body cavity insertable type includes: a handpiece; a supporting rod that is elongated from the handpiece; an ultrasound probe that includes a housing that is connected to the supporting rod and an ultrasound transducer that is fixed to the housing; and an ultrasound transmission medium circulation mechanism that is configured to discharge an ultrasound transmission medium filled in an ultrasound transmission space that is formed at a front of the ultrasound transducer and to inflow the discharged ultrasound transmission medium to the ultrasound transmission space again. The housing and the ultrasound transducer are configured such that the ultrasound transmission medium filled in the ultrasound transmission space is prevented from inflowing to a rear space of the ultrasound transducer.

Abstract: A cooling plate includes an inlet port, an outlet port, a planar first metal sheet, and a second metal sheet disposed on the first metal sheet. The second metal sheet has stamped and crimped regions that define one or more fluid channels to circulate a cooling fluid within the cooling plate, the one or more fluid channels fluidly coupled to the inlet port and the outlet port. The cooling plate can be in thermal communication with a battery module for an electric vehicle.

Abstract: An ultrasound apparatus of a body cavity insertable type includes: a handpiece; a supporting rod which is elongated from the handpiece; an ultrasound probe which is connected to the supporting rod and is configured to be able to be inserted in the body cavity; and a sealing cover which is separably coupled to the ultrasound probe to at least partially surround the ultrasound probe in a longitudinal direction from a distal end thereof. The ultrasound probe includes: a piezoelectric element; and a housing to which the piezoelectric element is mounted. An end of the housing is connected to the supporting, and the housing is provided with an ultrasound passing hole which is disposed outside the supporting rod. The sealing cover has an ultrasound passing window which is formed at a position corresponding to the ultrasound passing hole.

Abstract: A structure is mounted in a water jacket for a cylinder block of an engine so as to surround a block bore. The structure includes a body forming a pad mounting portion being a panel formed in an arc shape to have inner and outer curved surfaces that are surrounded by the block bore. A mounting hole is extended through the inner and outer curved surfaces of the pad mounting portion. A pad is formed in a shape to correspond with the mounting hole. The pad has a curved surface and is inserted into the mounting hole in a water tight manner.

Abstract: Disclosed herein are a CDMA optical system and encoder and decoder included therein. Time domain encoding means creates a time domain code having a sequence according to inputted data bits or a complementary code which is complementary to the time domain code. An optical modulation means selectively outputs lights, in which the lights are incident upon the optical modulation means from the outside, to two output leads, respectively, according to chip bits of the time domain code or the complementary code. A wavelength domain encoding means encodes the light outputted from a first output lead of the optical modulation means to a wavelength domain sequence (two dimensional code), transmits the wavelength code to the base station, encodes the light outputted from a second output lead to a complementary sequence of the wavelength domain sequence, and transmits the complementary code of the two dimensional code to the base station.
