IPC: G11B5/235
Filed: 1978-05-19
Abstract: PURPOSE: To achieve the improvement in high frequency reproduction sensitivity by interposing a for sterite layer as a gap spacer between the gap opposing faces of core materials in the magnetic head.  
     CONSTITUTION: Cores 2, 3 formed with a 2MgO.SiO 2  film 1 are bonded by using glass 4 with the film 1 being held sandwiched as a spacer, wherein 2NgO.SiO 2  will not deteriorate at up to 1000°C, hence bonding by the use of high melting point glass of high mechanical strength is feasible. The coefficient of thermal expansion of 2MgO.SiO 2  is equal to that of ferrite and its Vickers hardness is higher than that of ferrite, thus it can sufficiently satisfy mechanical strength, too. This enables the head of superior high-frequency reproduction sensitivity to be obtained in high density recording wherein the shortest recording wavelength is 1μm or under.

IPC: G01F1/075
Filed: 1979-05-17
Abstract: PURPOSE: To accurately control the combustion of a water heater with a small amount of vane wheel-actuating water by opening and closing an optical path by a rotary plate rotating in accordance with a vane wheel which is rotated by water applied thereto, and detecting a signal representative of the opening or closing of the optical path.  
     CONSTITUTION: Water is supplied to a water passage 5 to rotate a vane wheel 6. In accordance with the rotation of the vane wheel 6, a rotary plate 7 having recesses 7a is rotated. An optical path of the light from a light emitting element 9 toward a light receiving element 10 is opened and closed with the recesses 7a and projections at a peripheral portion of the rotary plate 7. An element 10 is turned on and off in accordance with the opening and closing of the optical path. In accordance with the operation of the element 10, an electric current flows to a differential capacitor 16 so that a voltage l 0  proportional to the flow rate of the water in the passage 5 is generated at both ends of a resistor 21. When the output l 0  has exceeded a reference voltage V 24d  set by resistors 22, 23, at an input terminal 24d of a voltage comparator 24, an output terminal thereof is in an H-state. As a result, a transistor 28 is turned on, and a contact 31 of a relay RL29 is closed. A supply valve 2 is then opened, and a burner 1 is ignited to obtain hot water owing to a heat exchanger 3. When the vane wheel 6 is stopped, and output l 0  is decreased so that the transistor 28 is turned off. As a result, the contact 31 is opened to stop supplying an electric current to the supply valve 2. Consequently, the combustion of the burner 1 is stopped.

Filed: 1989-03-14
Abstract: PURPOSE:To design a computing element consisting of a simple circuit without requiring a multi-input adder by obtaining the value of a current source as the product of a linear map input value and a weight, and obtaining the value of the linear map as the sum of the potentials of the current source of a boundary part.

Further the current sources at the boundary part are grounded through the resistance lines at the same resistance value (r) and the other terminals of the all current sources J are grounded. In such a circuit, the current value in the direction from one terminal to the other terminal of the current source is obtained as the product of the linear map input vector and the weight vector, and the linear map value can be obtained as the sum of the potentials at one edge of the current source at the boundary part. Thus the simple grating type network circuit can be used without using the multi-input adder, and the design can be facilitated.
