IPC: G01K7/00
Filed: 1978-06-02
Abstract: PURPOSE: To eliminate the loss of a normal power supply by arranging two contacts, which are electrically opened, and an easily melting alloy, wich is insulated from the former, in a container so that the alloy is melted, when a temperature rise exceeding the melting point of the alloy takes place, thereby to render the aforementioned two contacts conductive.

Incidentally, the alloy 6 has such a melting point as is adjusted to the temperature to be detected. The alloy 6 arranged thereabove is melted by the temperature rise higher than the melting point so that it instantly flows down into the space between the two contacts 8. As a result, the two contacts 8 are rendered conductive so that a warning device operates to inform the abnormal temperature rise.

Title: Stationary blade for axial-flow fluid machinery
Inventor: KANO YOSHIO
IPC: F01D9/02
Filed: 1990-03-19
Abstract: PURPOSE:To enable it to convert the extent of fluid energy into work so effectively through a moving blade by decreasing a circumferential tilt angle at each position in the radial direction of the rear edge of a stationary blade gradually toward the tip from the root. CONSTITUTION:A stationary blade's rear edge 6 is made up into a curved form, while a tilt angle thetar in the blade root is formed to be larger than another tilt angle thetat at the blade tip. In brief, these angles are set down to a relationship of thetar>thetat>0, and the middle is formed so as to get the tilt angle dwindle away. With this constitution, since the tilt angle thetar at the blade root is large enough, such a force as pressing a fluid in the root direction is sufficiently produced in and around the blade root, the fluid comes to a fluid little in a radial speed component. In addition, since the tilt angle thetat at the blade tip is small, pressing force in the blade root direction of the fluid is small too, so that the fluid in and around the blade tip is no longer separated from an outer circumferential wall surface. Therefore inherent energy of the fluid can be converted into work to the fullest extent.

Abstract: PURPOSE:To enable a flat junction to be formed regardless of deep diffusion exceeding 10mum without separating a group V element compound of zinc on the surface by a method wherein the surface of specified semiconductor is coated with a zinc oxide skin film containing specified amount of silicon oxide and then zinc is diffused while impressing the peripheral part with zinc and group V element pressure. CONSTITUTION:The surface of N type III-V compound semiconductor 1 is coated with zinc oxide skin film containing silicon oxide exceeding 10% by sputtering process and then the substrate is placed in an enclosure tube together with group V element compound 3 of zinc to be diffused for specified time at specified temperature until the depth thereof attains to specified value. The zinc vapor in the enclosure tube, after diffusing the coating film, reaches the surface of specified compound semiconduc tor substrate further to be diffused in the compound semiconductor substrate. At this time, the surface concentration of zinc is kept constant resultantly flattening the junction surface formed by the diffusion. When the zinc vapor is diffused down to the specified depth to be cooled down and then the skin film is removed in the later process after opening the enclosure tube, the V group element compound 3 of zinc formed on the skin film can be removed simultaneously without disturbing the formation of an ohmic electrode.

Title: Hot-line earth resistance meter

IPC: G01R27/18
Filed: 1987-03-19
Abstract: PURPOSE:To accurately measure earth resistance even if there is floating electrostatic capacity to the ground and induction in a hot-line state by utilizing a DC current for the whole circuit and reducing the influence of an AC component by using reactors and a capacitor. CONSTITUTION:Two reactors 20 and 21 are connected between cables and the capacitor 25 which has large capacity is connected between the neutral point between the reactors 20 and 21 and the ground. A DC power source E22, a limiting resistance R23, and a DC ammeter 24 which are connected in series are connected to the capacitor 25 in parallel. Consequently, when the cables are viewed in terms of DC, the capacitor 25 is infinite in resistance and the reactors 20 and 21 are zero, so the deflection on the DC ammeter 24 is zero unless grounding is performed. When the grounding is performed, the deflection I on the ammeter 24 is I=E/(R+earth resistance RX) and the earth resistance RX of the DC ammeter 24 is graduated in consideration of even the limiting resistance 23 to know the secure earth resistance.

Abstract: PURPOSE:To make a filter circuit simple and compact, by modulating reference sinusoidal waves by high-frequency waves, changing the modulated signal back into the sinusoidal waves as an AC output and applying a portion of the output to a multiplication circuit through a voltage comparison circuit. CONSTITUTION:The clock signal of an oscillation circuit 1 is frequency-divided by a frequency division circuit 2, the output of which is applied to a sinusoidal wave generation circuit 3.
