Title: Semiconductor memory
Inventor: ZAITSU KATSUNORI
IPC: G11C11/405
Filed: 1989-01-17
Abstract: PURPOSE:To reduce the malfunction of a sense amplifier at data readout and to decrease the sense time by providing a 2nd transfer gate using a same word line for a 1st transfer gate as a gate input to an opposite pole of a capacitor and having other digit line and a contact in pairs. CONSTITUTION:A 1st transfer gate 1 uses a word line 6 as a gate input, and connects one end to a capacitor 2 and other end to a digit line 4. A 2nd transfer gate 3 uses a word line 6 as a gate input, connects one terminal to an electrode of a capacitor 2 with respect to the 1st transfer gate 1 and connects the other terminal for a digital line 5. Thus, at data write, independently of the input data, a potential difference between two digit lines 4, 5 is applied nearly directly across the capacitor 2, and at data readout, charges of both polarities are discharged to the digit lines 4, 5 through the 1st and 2nd transfer gates 1, 3 from both the poles of the capacitor 2. Thus, the sense time at data readout is reduced to prevent malfunction.

Title: Substrate for semiconductor device
Inventor: KUDO KAZUNAO
IPC: H01L23/14
Filed: 1985-01-22
Abstract: PURPOSE:To obtain a substrate, which radiates heat efficiently and has excellent electric insulation even in a high humidity environment, by providing a metal substrate having good heat conductivity, an electric insulating inorganic material layer, which is formed by vapor growth method on the metal substrate and a thin insulating resin layer, which is applied on the inorganic material layer. CONSTITUTION:An electric insulating inorganic material layer 2 is formed on the surface of a metal substrate 1 by a vapor growth method. A thin insulating resin layer 3 is applied on the layer 2. By coating the inorganic material layer 2 by the thin insulating resin layer 3, the recess parts of the irregularities on the inorganic material layer 2 are filled, and the irregular thicknesses of the insulating layer are made few. Intrusion of moisture and conducting ions through the thin parts of the inorganic material layer 2 and intrusion of moisture and conducting ions through crystal grains of the inorganic material layer, which is grown in vapor phase, are blocked by the layer 3 as a blocking layer. Thus deterioration of insulating property can be prevented even if the substrate for the semiconductor device is placed in a high humidity environment.

Filed: 1982-01-26
Abstract: PURPOSE:To cause an intense swirl in a combustion chamber, by providing a rotary valve to extend across an intake passage eccentrically thereto to conduct intake air to one side of the passage so that the air flows along one side the inner wall of an intake port. CONSTITUTION:When an engine is working under low load, the relativelystrong negative intake pressure in an intake manifold 17 is introduced into the negative pressure chamber 32 of a negative pressure diaphragm unit 30 to move a diaphragm 31 rightward against a spring. As a result, the spindle 20 of a rotary valve 18 is turned through a rod and a lever 29 to rotate a valve element 19 to a position shown by a full line in the drawing, to cover a part of an intake port 16. For that reason, intake air flows along one side of the intake port 16 as shown by an arrow C, as that an intense swirl is caused in a combustion chamber 13. When the engine is working under high load, the negative intake pressure is so weak that the valve element 19 is turned to a position shown by a chain line. As a result, the efficiency of charging into the combustion chamber 13 is kept high.

Title: System state management system
Inventor: IKEO TADASHI
IPC: H04B3/46
Filed: 1990-01-19
Abstract: PURPOSE:To facilitate the correspondence of a management station by devising the system such that all stations receiving system state management information from the management station give a reply to the management station. CONSTITUTION:The system state management information is updated at the management station 1 and sends the result to all stations. The station 1 keeps reception of a reply from stations 2 and sends the information again to a station returning no reply at a point of a prescribed time after the transmission. The station waits for a reply for a prescribed time. When no reply comes regardless of repetition of retransmission for a prescribed number of times, the station 1 regards the station as a faulty station to revise the system state management information and sends the result to all the stations. When a reply comes during retransmission, it is regarded that the management information is sent to all the stations and succeeding change information is awaited. Through the constitution above, the state resulting in system-down such as dissidence of system state among the stations is avoided and the circuit network system with high reliability is realized.

Filed: 1989-01-20
Abstract: PURPOSE:To manufacture wafers having no interfacial transition layer in excellent reproducibility by a method wherein the substrate surface is exposed to a yellow ammonium sulfide solution and then heat-treated successively. CONSTITUTION:A semiinsulating GaAs substrate 11 is etched away by adopting a standard processing means of GaAs. Next, the residual natural oxide film on the surface after etching process is removed by immersing the whole body in HCl solution for around one minute and then immediately washed and dried up by N2 blowing process. Next, the surface is sulfurized. For the sulphatization, the substrate 1 is immersed in (NH4)2Sx solution prepared in a vessel capable of being sealed to be sealed up and left as it is. Later, a sulfide in around monoatomic layer degree is deposited on the substrate surface by heat-treating the surface at the temperature exceeding 100 deg.C. Later, the semiinsulating GaAs substrate 11 is mounted on an ordinary epitaxial device so as to form an epitaxial deposition layer 12. Through these procedures, wafers having no layers in abnormal carrier concentration on the interface between the epitaxial deposition layer and the GaAs substrate can be manufactured in excellent reproducibility.

Title: Rotor-type windmill with vertical axis
Inventor: ŠČERBINA ALEKSANDRS
IPC: F03D11/00
Filed: 2007-07-26
Abstract: The invention refers to the wind power industry, particularly - to the vertical - axis rotor-type wind turbines, which can be used for electric generators and correspond with the needs of consumers of other types of mechanical power. The vertical - axis rotor-type wind turbine contains vertical shaft (1), which is securely mounted in support (2) and rotor unit (3), comprised of two lattice-type blocks (4) and (5) with power elements - the sets of aerodynamic blades (6), where each of them holds two lattice girders 71, 72 and 81, 82. Each lattice-type block is equipped with relevant upper 91, 101, and lower bandage racks 92, 102, where the relevant end parts of the aerodynamic blade sets are fastened. By means of using as power elements the lattice of the rotating blades, a deeper expansion of thermodynamic air or sometimes a compression process are provided in the inter-blade ducts of said lattices, namely, while air is blowing over the lattice blades, the air pressure might either decrease or increase. Together with the change of pressure also the Kelvin temperature of the airflow changes. The total energy of gas flow is equal to the enthalpy of the brake action and it makes up the sum of the airflow enthalpy and the kinetic energy of said flow therefore the efficiency of application of the wind energy considerably increases.

Title: Method for control of operation conditions of wind turbine and device for its realization
Inventor: VĪBA Jānis
IPC: F03D7/06
Filed: 2015-02-27
Abstract: The invention pertains to the field of wind power engineering. Its objective is to increase the efficiency of wind energy transformation. The proposed method for control of operation condition of wind turbine is realized by mounting of turbine rotor athwart to the direction of airflow, by fastening of at least one plane blade to the rotor and by changing orientation of blade’s working surface relative to airflow direction during rotation of the rotor. Each blade during rotation of the rotor is turned about axis, parallel to rotor’s longitudinal axis, by an angle alpha between blade’s working surface and direction of incoming wind flow. Besides, turning angle alpha of blade’s working surface is determined by formula: alpha = pi/4 + 0.5phi, where phi is turning angle of radius, which connects central point of rotor’s cross-section and rotation axis of blade, relative to oposite direction of incoming wind flow. The device intended for realization of the method is characterized in that each blade is fastened to the rotor with a cylindrical axial hinge, which longitudinal axis is parallel to the rotor’s longitudinal axis. Rotation axes of rotor and blades are mutually interconnected with transmission, besides the ratio of angular rotation frequency of rotor to turning frequency of blades is equal to 2.
