Abstract: The brake system comprises an impeller (31) selectively connected to a propeller shaft (1) of a vehicle for consuming an energy of the engine and applying a brake force to the propeller shaft (1), an impeller housing (32) for rotatably housing the impeller (31) and defining an air passage (38) for introducing/discharging air to/from the impeller (31), a throttle valve (41) disposed in the air passage (36) upstream of the impeller (41) for adjusting the air flow rate in the air passage (38), and a negative pressure actuator (44) for moving the throttle valve (41) in accordance with the air flow rate in the air passage (37). The throttle valve (41) is moved by the negative pressure actuator (44) in accordance with the air flow rate in the air passage (37). In other words, the brake system adjusts the brake force mechanically by itself in a manner such that an excessive brake force is never applied to the propeller shaft (1). The brake system does not require a cooling device and only requires a simple arrangement for controlling the brake force.

Abstract: A catheter equipped with an expansible member (3) according to the present invention comprises a first lumen (4) whose tip is open, a second lumen whose tip is closed, a foldable expansible member (3) communicating with the second lumen (6), and a rigidity imparting member (13) consisting of a linear member extending in the axial direction disposed in the second lumen. Therefore, an extreme flection or bend of the catheter is prevented without decrease of the flexibility of the catheter, especially the elastic deformability in the lateral direction with respect to the axial direction of the catheter. Thus, the force applied to the base end portion of the catheter for advancing the tip end portion thereof is surely transmitted to the tip end portion. Further, a catheter equipped with an expansible member according to the present invention comprises a first lumen whose tip is open, a second lumen whose tip is closed, and a foldable expansible member communicating with the second lumen, the outer diameter of the tip end portion of the catheter including a portion to which the expansible member is attached is smaller than that of the base end portion of the catheter. Therefore, the tip end portion of the catheter can be inserted into a severer stricture portion or in a more peripheral blood vessel. Further, a catheter equipped with an expansible member according to the present invention comprises a first lumen whose tip is open, a second lumen whose tip is closed, and a foldable expansible member communicating with the second lumen, the tip of the expansible member forming the tip of the catheter. Therefore, the expansible member is prevented from peeling off and the tip end of the catheter is prevented from being an injury to the inner wall of a blood vessel when the catheter advances in the blood vessel.

Abstract: A brake apparatus for use in a motor vehicle having at least one front wheel (3a, 3b) and at least one rear wheel (3c, 3d). The brake apparatus inclues a diagonal braking pressure supply system provided between a master cylinder (2) and wheel braking cylinders for applying braking forces to the front and rear wheels. A proportioning valve (120, 220) is provided in the braking pressure supply system for controlling the braking pressure to be applied to the rear-wheel braking cylinder in accordance with a control signal so as to vary the ratio of the braking pressure to the rear-wheel braking cylinder with respect to the braking pressure to be applied to the front-wheel braking cylinder. Also included is an electronic control unit (500) which produces the control signal to the proportioning valve. The electronic control unit obtains a command value on the basis of a parameter corresponding to the difference between the lock states of the front and rear wheels which are in turn obtained on the basis of signals indicative of speeds of the front and rear wheels. The control signal is determined in accordance with the command value and supplied to the proportioning valve (500).

Abstract: A current sensing circuit includes a first reference resistor (Rp) connected in series with the source-drain path of a current mirroring transistor (T2) across the source-drain path of a power transistor (T1) which is N times the size of the current mirroring transistor. Due to the first reference resistor (Rp), the current in the mirroring transistor is less than 1/N the current in the power transistor. To sense the current in the power transistor more accurately, the current sensing circuitry includes a reference circuit (22) in which the source-drain path of a compensating transistor (T3), of like size as the current mirroring transistor (T2), is connected in parallel with a second reference resistor (RR) to produce a reference current (IR) which is approximately equal to 1/N the current flowing in the power transistor (T1).

Abstract: This invention relates to a method for preparing an offset shape of a cutting tool for a workpiece in a numeric controller for making a turning work. More particularly, use is made of a cutting tool having blades on both sides, each of the blades of which has a nose R and moves in both horizontal and vertical directions with respect to the rotating workpiece. When the vertical coordinate value of the work shape increases, the blade on the reference side is employed for the cutting and when the vertical co. ordinate value decreases, the blade on the opposite side is employed. In such a case, a cutting tool is used which further has blades on both sides, each of the blades of which as a nose R and is connected to the other at a predetermined angle e of inclination, and which moves in both horizontal and vertical directions with respect to the rotating workpiece. When cutting is made by the reference blade when the inclination angle of the work shape in the vertical direction is smaller than the angle 9 of the blade and by the blade on the opposite side when the angle of inclination of the work shape in the vertical direction is greater than the angle θ of the blade, the offset shape is prepared by use of the center of the tip of one of the blades of the cutting tool having the nose R on both sides as the control point in accordance with the final work shape, it becomes thus possible to make cutting by use of the cutting tool having blades in both sides in a machine tool using a numeric controller, and to shorten the cutting time.

Title: Photon scanning tunneling microscopy.
Inventor: FERRELL THOMAS L
IPC: G01B9/04
Filed: 1989-10-20
Abstract: A method and apparatus for photon scanning tunneling microscopy for examining a sample in a sample area on a surface at a subwavelength resolution is disclosed. The method comprises generating a near-field of photons at a surface containing a sample area. The near-field has an area that is larger than the sample area, and the near-field has an exponentially increasing intensity in a direction perpendicular to and towards the surface. The near-field is sampled with a probe which receives photons from that near-field that tunnel from the surface to the probe. The received photons are detected and a detector produces an output signal that is proportional to the number of photons received by the probe. The sample area is scanned with the probe in at least one direction parallel to the surface. While scanning, the probe may be maintained either at a position of a constant near-field intensity or at a position of constant distance from the surface. A photon scanning tunneling microscope for using the method is also disclosed.

Abstract: A broadband space switch matrix constructed from a plurality of NAND gates (10-70) arranged into a set of cascaded stages to form a tree-switch multiplexing con­figuration. A plurality of input digital signals are applied to input ports (1-4) coupled to the NAND gates (10, 20, 30, 40, respectively) in the first stage (No. 1). A selected one of the input signals (A) emerges as an output signal ( A ) from an output port (74) coupled to a single NAND gate (70) in the last stage (No. 3). Each NAND gate (10) has a select line (SEL11) for receiving control signals. The switching path for the selected input signal is established by placing the sequence of NAND gates (20, 50, 70) defined by the selected switching path in a state of conduction whereby only the selected input signal propagates through the switch. This is effected by forcing to a HIGH state the particular NAND gates in each stage whose outputs are coupled to the same NAND gate in the following stage along with the output of the NAND gate in the current stage which is in the chosen path. The forced HIGH state is achieved by applying a LOW state signal to the respective select lines of these par­ticular NAND gates (10 and 60). In an alternate arrange­ment, the NAND gates in the first stage (No. 1) are replaced by 2:1 pass-transistor-selectors which offer a reduction in the number of transistors.

Abstract: Dilute molasses solutions are generally acidified with the aid of sulphuric acid and then employed as nutrient medium for fermentations. However, used nutrient solutions lead on anaerobic methanisation, because of the sulphate content, to biogas containing hydrogen sulphide. It is now possible to acidify molasses solutions to an adequate extent with the aid of ion exchangers. These molasses solutions are comparable with customary molasses solutions in fermentations, and they produce an improved biogas in the methanisation.
