Title: Coupling element for charge
Inventor: FUJI TATSUO
IPC: H01L29/762
Filed: 1980-06-10
Abstract: PURPOSE:To determine the transfer direction of charges unidirectionally by a simple two-phase clock drive type by a method wherein the first and the second dielectric layers are formed on the surface of a semiconductor substrate, and a plurality of conductor electrodes are arranged on the surface at regular intervals. CONSTITUTION:A thermally oxidized SiO2 layer 12 is formed on the surface of the P type Si substrate 11, and an Si3N4 layer 13 is made up on the layer 12. A plurality of Al electrodes 14 are disposed adjacently on the surface of the layer 13. Each electrode 14 is wired to terminals 16 by wiring 15. In such constitution, electrons in the substrate 11 are trapped on the interface of the layer 12 and the layer 13 or in the layer 13 through the layer 12 when not less than 20V positive pulses to the substrate 11 are applied to the terminals 16. Accordingly, the concentration of holes in the vicinity of the surface of the substrate 11 under the electrodes 14 becomes higher than the concentration of holes in the substrate 11. The difference of the concentration of electrons in the vicinity of the surface of or in the substrate 11 under the electrodes 14 is made differ successively by increasing or decreasing the amount of charges injected and held in order according to the arrangement of the electrodes 14. Thus, the transfer direction of charges is determined in two-phase clock drive.

Title: Short-circuit accident detecting method
Inventor: AKIYAMA GAKUO
IPC: G01R31/02
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To quickly detect a short-circuit accident, and to shorten a time until the start of the operation of a short-circuit current suppressing device and a semiconductor breaker or the like. SOLUTION: The voltage actual value of a system voltage is detected (1-4), and transmitted through a low pass filter 5 so that higher harmonics distortion included in the system voltage can be removed. Then, the rate of the output of the low pass filter to data before 1 mSec preserved in a buffer 6 is calculated so that the time change rate (voltage fluctuation rate) of a voltage can be obtained. This voltage fluctuation rate is compared with a set value (0.05), and the decrease of the voltage based on a short-circuit accident is detected. Thus, the voltage decreasing mounts sufficient for judging the accident can be reduced by removing the higher harmonics distortion, and the detection of the decrease of the voltage can be attained with a small set value (0.05), and a short-circuit detecting time which is several mSec in a conventional manner can be reduced into several 100 Msec.

Abstract: PURPOSE: To grow a compound semiconductor of Groups II-VI having high completeness of the crystal, by using Te which is an element of Group VI as a main component of a solvent, retaining the vapor pressure of an element of Group VI which is a constituent element different from Te at a specific value, and growing the crystal of a compound semiconductor.  
     CONSTITUTION: This method is particularly effective for growing a semiconductor consisting of a compound of Groups II-VI, preferably ZnSe. Thus, Te containing Se which is an element of Groups VI different from Te is used as a main component of a solvent. The use of Te and a mixed liquid containing Se as the solvent controls the deviation from the stoichiometric composition and controls the crystallinity and electric conduction type effectively. The temperature difference liquid phase growing method adopted in the present method is capable of depositing the crystal continuously always from the high temperature part to the lower temperature part by the temperature difference formed in the solvent. The Te content in the formed ZnSe is considered 0.1% or less, and p type crystals can be obtained readily.

Abstract: PURPOSE: To enable the automatic adjustment of a water level at an upstream side of a bagform weir, by a method wherein the bagform weir, which is installed at a river bed across a river, is caused to automatically fall down according to the water level.  
     CONSTITUTION: When a water level at an upstream side exceeds an estimated water level 13, an opening part 23a of a pipe 23 sinks under the water resulting from the rise in the water level in a water adjusting casing 21, and a pipe 11 is isolated from the air. Then, a cyphone action acts on the pipe 11 to increase a drainage amount through the pipe 11, and a water level 1 in a water pressure adjusting chamber 9 falls resulting from the unsufficient supply of water from a water conducting hole 10. When a water level in the chamber 9 is below a water level of a water chamber 1b in a weir 1, water in the chamber 1b is discharged to bring down the weir 1. When a water level 17 at a doenstream side rises due to flood and the like, the pipes 20, 23, and 11 are isolated from the air. Then, a cyphone action acts on the pipe 11, the water level in the chamber 9 begins to fall irrespective of a water level of a river 7 at an upstream side, and when the water chamber 1b, the weir 1 falls down. As a result, water at the upstream side overflows over the weir 1.
