Abstract: A semiconductor laser device includes a substrate having one of p- and n-conductivity types, and a current constrictive layer formed on a surface of the substrate and having the other type of conductivity. The current constrictive layer has a through-channel extending to the surface of the substrate for defining a current path in a direction perpendicular to the surface of the substrate. The through-channel is of a belt-like pattern extending in a direction perpendicular to end surfaces of the substrate. A third cladding layer having the one type of conductivity is filled in the through-channel, a surface of the third cladding layer being flush with a surface of a current constrictive layer. A first cladding layer, an active layer, and a second cladding layer which constitute a double heterostructure are formed over the third cladding layer and current constrictive layer.

Abstract: A first longitudinal grip force FGG is calculated by differentiating a vehicle body speed by time. A driven wheel torque is calculated from an engine torque and a second longitudinal grip force FGT is calculated from the driven wheel torque. The first longitudinal grip force FGG and the second longitudinal grip force FGT are compared with each other, and the higher one of such grip force is selected as a longitudinal grip force TG. When the vehicle travels on a normal flat road, the first longitudinal grip force FGG obtained from the vehicle body speed is selected. But when the vehicle travels on an ascent road, on which the first longitudinal grip does not indicate an accurate value, the second longitudinal grip force FGT obtained from the engine torque is selected. With this arrangement, the longitudinal grip force is accurately estimated even if the vehicle travels on such an ascent road.

Abstract translation: 第一纵向夹紧力FGG是通过按照时间差分车体速度来计算的。 从发动机扭矩计算从动轮扭矩，并且根据从动轮扭矩计算第二纵向夹紧力FGT。 将第一纵向抓握力FGG和第二纵向抓握力FGT彼此进行比较，并且将这种夹持力中的较高者选择为纵向抓握力TG。 当车辆在正常平坦的道路上行驶时，选择从车体速度获得的第一纵向抓握力FGG。 但是，当车辆在上坡道上行驶时，第一纵向把手不指示准确值，则选择从发动机扭矩获得的第二纵向夹紧力FGT。 利用这种布置，即使车辆在这样的上升道路上行驶，也能够准确地估计纵向抓地力。

Abstract: An improved expansion valve (10) disclosed for use with an air conditioning system (12) for an automobile. High pressure regrigerant flow is modulated through the valve by movement of a valve member (92) in response to the superheat of the low pressure refrigerant flow through a first passage (32) in the expansion valve. The low pressure regfrigerant superheat is sensed by a power element (74) containing an adsorbent and gas which deflects a diaphragm (82) to a degree related to the superheat of the low pressure flow. The diaphragm acts on an annular seal retainer (100) to modulate the position of the valve member (92). A cupshaped high pressure seal (104) is provided between the valve member (92) and wall of the passage (54) in which the valve member moves to balance the forces on the valve member exerted by the high pressure refrigerant. The balanced valve member allows use of a compact power element, permitting the body (30) of the valve (10) to be formed of plastic.

Abstract: A device for dispensing a liquid, including a container having an interior space accommodating the liquid, a first valve attached to the container, a delivery path having one end submerged in the liquid and extending through the container such that the other end is outside the container, and a second valve disposed in the delivery path for closing and opening the delivery path. The first valve permits a pressurized gas to flow therethrough into the container to raise the pressure within the container, but inhibits a discharge flow of the pressurized gas and the liquid therethrough out of the interior space. The liquid is delivered out of the container through the delivery path, due to the raised pressure within the interior space. The device has a micro-porous membrane filter disposed in a portion of the delivery path which is located upstream of the second valve, as viewed in the direction of delivery of the liquid. The micro-porous membrane filter removes microorganisms from the liquid delivered from the delivery path.
