Abstract:
The cell viability in cell transplantation is improved so as to achieve sufficient repair of organ. There is provided a regeneration treatment apparatus comprising: a heart rate detector which detects a heart rate of a patient; a memory part which stores a heart rate prior to stimulation; stimulating electrodes which stimulate a vagus nerve that controls an organ having transplanted cells; and a control unit which controls an intensity of a stimulation signal to be output from the stimulating electrodes to the vagus nerve so that the heart rate of the patient detected by the heart rate detector is decreased by 5 to 20% as compared to the state prior to the stimulation.
Abstract:
A housing of an electric motor includes an inner circumferential surface, which includes recesses arranged along the circumferential direction. On an outer circumferential surface of a stator core of a stator are provided protrusions arranged along the circumferential direction. Fitting each protrusion to the corresponding recess fixes the stator core to the housing. A rotor is provided radially inward of the stator. In a state where each protrusion is fitted to the corresponding recess, a pair of side surfaces of each protrusion are retained by a pair of inner side surfaces of the corresponding recess in the circumferential direction of the housing. A gap is formed between an end face of each protrusion and an inner bottom surface of the corresponding recess facing the end face along the entire surface of the end face.
Abstract:
A plurality of convex portions are located inside of a virtual circumferential surface. Each convex portion connects an adjacent pair of circumferential portions with each other. Each convex portion is an arcuate curve bulging radially outward. Each convex portion defines a minimum radius. A difference between a radius R and the minimum radius is a depth Dh. Dhr=Dh×25.5/R. A range of an angular width A in relation to circumferential portion and a range of the depth Dh are set by the following expression, (5.6×Dhr+11.3)°×6/p≦A
Abstract:
A detection device for passengers includes a passenger judgment unit which has a specified load judgment unit and a stability judgment unit, and a plurality of load sensors disposed on supporting parts of a seat of a vehicle. The passenger judgment unit makes a judgment on a state of a passenger on the seat of the vehicle according to output values of the plurality of load sensors. If a summation of the output values of the plurality of the load sensors is judged to fall into a specified load range of a child-seat by the specified load judgment unit, the passenger judgment unit will make a judgment on whether the child-seat is attached to the seat or not according to a summation of detected output values of the plurality of the load sensors detected when the stability judgment unit judged that the output values of the plurality of the load sensors are in stable state.
Abstract:
A rotating electric machine including circumferential portions respectively corresponding to magnetic pole centers of permanent magnets and defined along the outer circumference of the rotor at a plurality of locations, with each circumferential portion extending along part of a virtual circumferential surface, which is coaxial with the rotor. The circumferential portions are spaced from one another in the circumferential direction. Convex portions connect adjacent pairs of the circumferential portions. Each convex portion is located radially inward from the circumferential surface, projects in a radially outward direction, and includes angled portions directed in the radially outward direction. The rotating electric machine suppresses decrease in the average value of the output torque and does not use reluctance torque to increase the average value of the output torque.
Abstract:
A hetero-epitaxial liquid phase growth method for growing a compound semiconductor by liquid phase epitaxy includes placing a melt in a closed melt boat on a substrate and epitaxially growing a first thin film, opening the melt boat while the melt remains in a melted state for a predetermined time to evaporate a component of the melt, and epitaxially growing a second thin film on the first thin film from the melt from which the component has been evaporated.
Abstract:
A quartz crystal oscillator package comprising a quartz crystal vibrator leaf enclosed in an evacuated housing. The vibrator leaf frame is sandwiched and sealed between a pair of housing elements formed by etching at one time the periphery of each housing element and at another time etching a concave portion in each housing element. Opposed concave portions provide the internal volume wherein the vibrator leaf is sealed under vacuum. Using heat and vacuum, a metal film deposited on the sealing surfaces of the housing elements fuses with a binder material to form a eutectic alloy seal. A flat package having small size, high structural strength, an excellent hermetic seal, and high internal vacuum is produced by this method.
Abstract:
A passenger detecting device includes a plurality of weight sensors, a passenger judging and data updating device and an update forbidding device. The weight sensors are arranged at different positions of a seat for respectively detecting weights acting on the seat of a motor vehicle. The passenger judging and data updating device is capable of judging a passenger on the seat based on the loads detected by the weight sensors and updating information on the passenger. The update forbidding device prevents the passenger judging and data updating device from judging the passenger or prevents the information to be updated when a sum-weight fluctuation amount is not less than a first predetermined threshold value, where the sum-weight fluctuation amount is obtained by summing up weight function amounts which are absolute values of fluctuations of the loads detected by the weight sensors.
