Abstract: The present invention comprises a column support fixed to a deck cross member extending along a width of a vehicle; a steering column supported by the column support; a column bracket disposed about an axis of the steering column in such a manner as to widen toward a front part of the vehicle, both ends of the column bracket being fixed to a body of the vehicle; and knee absorbers disposed at both sides of the column bracket, each of the knee absorbers having a base end fixed to the deck cross member and a front end facing the knees of an occupant, the front end coming into contact with the knees of the occupant. When the vehicle crashes, the occupant and his or her knees move forward to collide with the column bracket. The column bracket, however, is not displaced since both ends of the column bracket are fixed to the body of the vehicle. The knees of the occupant are guided forward along the surface of the column bracket to the right and left knee absorbers.

Abstract: A system and method for treating a stenosis or blockage in a bodily fluid passageway is described. The system includes a catheter and a controller for generating radio frequency energy along a pair of output lines, a monitoring circuit for monitoring the phase of the radio frequency energy along the output lines, and an impedance matching circuit for adjusting the output impedance of the generator so that it equals that of a load, e.g., the patient. The catheter includes a catheter body which is insertable into the bodily passageway and operatively connected to the controller. A lumen in the catheter body defines an opening and a stainless steel, metallic-plated mandril is disposed within the lumen so that a terminal end thereof extends through the opening and into the bodily passageway.

Abstract: In a turbocharger equipped with a motor/generator, the motor/generator gradually decreases its generator output without shifting abruptly from generation mode to motor mode when a vehicle starts accelerating during cruising at a constant speed or runs along an upward slope, thus preventing abrupt increases in the loading on an engine.

Abstract: Disclosed is a heated balloon catheter in use for effectively heating of the constricted zone of blood vessels deep thereinto, performing a proper temperature measurement, having further advantage of easy fabrication thereof.A 2 to 20 MHz radio frequency generator is connnected to heating electrode within a balloon and opposite electrode external of a patient respectively. A thermocouple mounted within the balloon is connected to an external temperature controller across paired conductors. A passive filter and an active filter are provided to eliminate said R.F. noise from said conductors. From R.F. generator is supplied R.F. energy to allow the capacitive current to flow through the patient's body via the electrodes, whereby a stenosis can be heated deep thereinto by capacitive heating. From the thermocouple is output the D.C. thermoelectric potential corresponding to the temperature to the temperature controller, of which the siganals are purified by said filters.

Abstract: The guide device for craning a container has guides so arranged that they can be moved vertically by a raising/lowering device mounted on the spreader body and can be positioned at the corners of the spreader. The guides are lowered by the raising/lowering device and secured to the bottom corners of the container held by the spreader. Then the spread parts of the guides project from the lower end of the container to secure the spreader to the container. The structure of the spreader is simple and the weight is light.

Abstract: In a refrigerator, the inner space of a heat insulated housing is divided to form a refrigerating compartment, a freezer compartment, and a vegetable compartment. A projection which contacts with the back of a cooler cover and divides the space behind the cooler cover into two chambers arranged in a lateral direction is formed on a back wall portion. The space enclosed by the projection, the cooler cover, and the housing is formed as a cold air passage for guiding cold air of the refrigerating compartment to the vegetable compartment. A damper device has a shutter plate, a bias spring which urges the shutter plate toward a cold air duct, and a shape memorizing alloy coil spring on which a heater is wound. A weak current is always supplied from a damper control device to the heater so that the temperature of the shape memorizing alloy coil spring is maintained at the Ms point (martensite phase transition start temperature) or higher under the state where the shutter plate is lifted up.

Abstract: A heated balloon catheter for treatment of constricted zones of body fluid passages by applying heat and pressure to the constricted zone. The heat is generated by transmitting, to an antenna within a balloon carried by the catheter, radio frequency energy of about 13.56 MHz. Measuring the temperature of the balloon inflating fluid and controlling the temperature of the balloon inflating fluid to prevent overheating of the zone being treated and providing an alarm if the balloon leaks or bursts.

Abstract: A low pass filter using two pseudo gyrators 10 and 20 is disclosed. The gate-source capacitances of field effect transistors forming the pseudo gyrator circuit can be considered to be included in capacitors for forming the low pass filter. Therefore, an ideal admittance matrix for a gyrator is obtained. Increase in integration density of the low pass filter can be achieved since the low pass filter is formed by a simplified pseudo gyrator circuit.

Abstract: A cascode amplifier having a 180.degree. phase characteristic is connected with in-phase feedback circuits having a 0.degree. phase characteristics. When viewed from an output side of the cascode amplifier, these circuits operate as inductive circuits having negative resistance. Thus, connecting a capacitor to the output of the cascode amplifier causes formation of a parallel resonance circuit, so that an oscillating operation is carried out. Since an inductor, i.e., inductive circuit can be structured without use of a transmission line, an occupied region necessary for formation of a microwave oscillation circuit is reduced.

Abstract: A power supply system for supplying electric energy to a rotary electric machine coupled to a rotatable shaft of a turbocharger for supercharging an engine includes a battery for supplying electric energy to the rotary electric machine, and a capacitor connected parallel to the battery through a switching control device. The capacitor is charged with electric energy from the battery at all times. When the engine needs to be revved up for quick acceleration, the switching control device is energized to supply electric energy stored in the capacitor, together with the electric power from the battery, to the rotary electric machine. Since the capacitor has a smaller internal resistance as compared with the battery, the capacitor can supply a large current to the rotary electric machine immediately after the accelerator pedal is deeply depressed for quick acceleration.

Abstract: A turbocharger control system controls a turbocharger associated with an engine mounted on a motor vehicle, the turbocharger having a rotary electric machine mounted on the rotatable shaft thereof. When it is determined that the motor vehicle is about to start, the rotary electric machine is operated as an electric motor to effect a flying boost increase before the accelerator pedal is depressed. The boost pressure of the turbocharger is therefore increased to increase the response of acceleration of the motor vehicle to the depression of the accelerator pedal when the motor vehicle is started.

Abstract: A turbocharger with a rotary electric machine has a permanent magnet, nonmagnetized metallic member, or surfaces of different light reflectivities fixed upon a rotatable member of the turbocharger, as a detectable means. The detectable means is disposed in a position corresponding to the angular position of magnetic poles of the permanent magnet rotor of the rotary electric machine. A detecting means is disposed in a position coacting with the detectable means for detecting the angular position of magnetic poles of the permanent magnet rotor. A shield means is provided for preventing the detectable means from being adversely affected by magnetic fields, oil, and dust, so that a detected signal of a high S/N raio can be produced for accurately detecting the angular position of the magnetic poles of the permanent magnet rotor as it rotates.
