Filed: 1979-05-23
Abstract: PURPOSE: To improve the heat transfer rate at heating surface on the air side by decreasing a temperature boundary layer between the dead water region of a heat pipe back flow and the heating surface with a fin shape.  
     CONSTITUTION: Slab fins 1 are arranged in parallel at constant intervals, and an air current fluidizes between them. A fluid flows in a heat pipe inserted at right angles in the slab fin 1. Then, a louvering 3 for which two sides facing the air current at right angles to the direction indicated by arrow are opened is provided on the slab fin 1 in a clearance in the step direction of the heat pipe, and projections 8, 9 almost in a circular arc shape and facing the air current in the direcrion indicated by arrow are provided on the slab fin 1 in a clearance in the row direction of the heat pipe. As a result, a boundary layer of the air current is made thin, mixing and turbulence of the flow are accelerated, a dead water region of the heat pipe back flow is decreased to improve heat transfer performance sharply, and from unifying a flow rate distribution of the air current, noises can sharply be decreased.

Title: Charged particle beam device
Inventor: HOSAKA SUMIO
IPC: F02B3/06
Filed: 1987-03-20
Abstract: PURPOSE:To hold opposite electrodes or a probe and a sample at an accurate distance by controlling the relative distance so that a tunnel current or electric field radiation current is held constant. CONSTITUTION:When the probe 2 is applied with a voltage Vt (<0) through a current detector 5, an electron 3 flows from the probe 2 to the sample 4. The tunnel current flows when the voltage is low or electric field radiation current flows when it is high. At this time, a current detector 5 outputs a signal corresponding to the electric field radiation current and a difference current detecting current 7 subtracts said signal from a voltage corresponding to a desired current to detect a difference current. The detected difference current is converted by an error position converting circuit 9 into an error quantity of distance. An actuator 1 is driven with this signal through a servo circuit 10 and a high-voltage amplifier 11 so that the error quantity is zero, thereby holding the electrodes or the probe 2 and sample 4 at the accurate distance.

Filed: 1989-03-17
Abstract: PURPOSE:To prevent the abrasion and melting of a wheel tire and prevent the burst of the wheel tire and shorten the time up to the realization of taxing speed and reduce the shock on rebounding by revolving the wheels in the normal direction before grounding. CONSTITUTION:Tires 5 and 5 are revolved beforehand in the normal direction at a landing revolution speed by allowing a motor 6 to conduct. Therefore, at a landing point, the tire 5 having the landing revolution speed obtains the landing speed of a plane body in a drastically short time. Therefore, the slip of the tire 5 for a runway is reduced by that portion, and the heat generation can be reduced drastically, and the abrasion and melting of the tire 5 due to the heat generation and the burst of the tire can be surely prevented. Further, the bound angle is reduced for the grounding angle of the tire in the normal revolution, and the shock on rebounding is reduced by that portion. In the brake application after grounding, a DC motor 6 acts for the power generation brake, and the heat generation in a conventional brake device can be reduced.

Title: Container for beveling machining
Inventor: ITO AKIRA
IPC: H03H3/02
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To conduct bevelling machining excellent in a symmetric property by setting a radius R1 from the center of a container larger than a curvature R2 of the inner peripheral part. SOLUTION: A beveling container 1 is made of the metal material (iron, non-ferrous material) having a radius R1 from a rotary shaft (the center of the container), a width D, a curvature R2 of the inner peripheral surface 2 (machined part). A ratio of the radius R1 and the curvature R2 is set at 2-10:1. An oscillator and the machining additive material are moved in the rotating direction with the rotation of the machining container 1, but they are slid for fall along the inner peripheral part 2 when the gravity becomes larger than the friction resistance by the centrifugal force. Shape of the machining container is transferred to the oscillator by this sliding. The oscillator and the machining additive material are moved like a pendulum in the machining container by continuing the rotation, but the oscillator is reversely rotated in the container by increasing the rotating speed to a constant value or more. Symmetric property of a surface and a back surface of the oscillator is secured by this reverse rotation.

CONSTITUTION:A one-dimensional pyroelectric sensor array 11 has a plate 12 made from a pyroelectric as its base. The pyroelectric plate 12 is in the form of a long rectangle and has a plurality of long slitlike spaces 13 formed by notching from its first side 12a to its second side 12b, to form a sensor portion 14 where the side 12a becomes a free end.
