Title: Measurement instrument of potential of power conductor
Inventor: UIRIAMU REIDO SUMISU BUANIZU
IPC: G01R19/25
Filed: 1987-10-28
Abstract: Self contained radio transmitting state estimator modules are mounted on power conductors on both sides of power transformers in electrical substations and on power conductors at various places along electrical transmission lines. They are electrically isolated from ground and all other conductors. These modules are capable of measuring current, voltage, frequency and power factor (or the fourier components thereof) the temperature of the conductor, and the temperature of the ambient air. The modules transmit these parameters to local receivers. The receivers are connected by an appropriate data transmission link, to a power control center which allows determination of the state of the power system. Appropriate control signals are transmitted back to the electrical switchgear of the system to bring it to the appropriate optimum state. Direct local control may also be effected, for example, the prevention of overloading a transformer. A <<donut>> state estimator module comprises a novel hot stick operated hinge clamp and a novel voltage sensor which measures the current between an isolated capacitor plate and ground. The donut measures the fourier components of voltage and current over a number of cycles and transmites the components to the local receiver. The local receiver derives the desired electrical measurements such as voltage, current, power factor, power, and reactive power and transmits them to local or remote control stations. Up to 15 donut modules may transmit on a single channel to a single local receiver. Each transmits at intervals which are an integral number. The intervals between transmissions of all donuts do not have a common factor and the average interval is the desired transmission rate. Each donut uses the zero crossover of current of its conductor to establish its transmission interval. The system is self-calibrating using known reference signals within the donut module.

IPC: F24S90/00
Filed: 1999-08-21
Abstract: PROBLEM TO BE SOLVED: To provide a heating (and cooling) system utilizing solar energy effectively and effective for saving oil and energy and for preventing warming of the earth. SOLUTION: A heat receiving panel 1 having corrugated structure is connected with an air header 2, an inlet duct 3, and an outlet duct 4 and divided into four blocks. A left block 1 indicates see-through state of a transparent glass. A heat accumulator 8 is coupled with the heat receiving panel through an air duct. When a circulation fan 7 is started, air in the system begins to circulate. Air from the circulation fan flows through the inlet duct system 3 and the heat receiving panel 1 and enters the air header 2 on the outlet side. The heat receiving panel 1 subjected to radiation heating with solar heat exchanges heat with passing air and the air temperature increases. Temperature raised air enters the heat accumulator 8 through an air duct and imparts heat to a heat storage material. The circulation fan 7 supplies air again and repeats air circulation.  When the air temperature reaches a level suitable for heating, air is supplied into a room.

Title: Method and apparatus for measuring thickness or refractive index of silicon thin film
Inventor: YAMAGUCHI IKUHIRO
IPC: H01L21/66
Filed: 1992-09-18
Abstract: PURPOSE:To measure the thickness of silicon thin film easily with high reliability. CONSTITUTION:A coherent light generating source 2 projects a near infrared light toward a silicon thin film sample 1, where a silicon thin film is formed on a transparent substrate, and a sensor 3 detects the intensity of transmitted light. A light intensity analog signal is delivered from the sensor 3 to an AD converter 5 where it is converted into a digital light intensity signal corresponding to the transmittance of silicon thin film in the silicon thin film sample 1. A CPU 4 then compares the digital light intensity signal with a digital standard light intensity signal corresponding to a standard transmittance prestored in a ROM 6 thus calculating the difference representative of variation of transmittance. A decision is made that the thickness of silicon thin film is acceptable if the variation of transmittance is within an allowable range otherwise it is rejected. Refractive index of silicon thin film can also be measured.
