Title: High speed tuning filter
Inventor: TAKAHASHI YUJI
IPC: H03J3/20
Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To suppress the increase of filter transmission loss and to suppress the increase of power consumption by constituting a high tuning filter so as to permit a voltage at the time of resonance in a main tuning circuit when a pin diode is turned-off to be divided by means of an additional capacitor, the second additional capacitor and the synthetic capacitance of electrostatic capacitance when the pin diode is turned-off. SOLUTION: When an opposite direction bias voltage is applied to the pin diode D1 so as to execute turning-off in a first additional capacitor circuit part, the open voltage V0 of a resonator (the main tuning circuit) is divided by the capacitance and the additional capacitors ΔC12 and ΔC11 so that the voltage applied on the pin diode D1 is lowered. In a same way, the pin diode D2 is also divided by the capacitance and the additional capacitors ΔC22 and ΔC21 in the second additional capacitor circuit part so that an impressed voltage V2 is lowered. The degree of the filter is 2 and tuned to four kinds of frequencies. Therefore, the pin diode to be used is low in voltage resistance and an effect that power consumption is saved is obtained.

Title: Uniform pipe expansion method
Inventor: KANBARA HIDEAKI
IPC: B21D39/20
Filed: 1978-08-30
Abstract: PURPOSE: To provide a uniformly expanded pipe excellent in fixability as well as water sealing by a process in which an axial compression load is given to an elastic medium for expanding pipes inserted into an intended pipe to raise the expansion pressure up to a set level and then, reduced after it is maintained under the set pressure for fixed time.  
     CONSTITUTION: A pipe expansion pressure detector having electrodes 15 and 17 with an elastic medium made of rubber or the like grasped at both ends and sensing sections 16 and 18 is inserted into a pipe 1. Then, when an oil pressure is given to a hydraulic cylinder 6, an axial load is applied to a pressure rod 3 so that the medium 4 is compressed to expand the pipe radially. When the pipe expansion pressure reaches a preset level Po for the detector 10, the detector is actuated to provide a detection signl. The signal sctivates a timer 12 set for a given time. At the same time, a solenoid valve closes a hydraulic circuit to maintain the pressure of the medium 4 at the level Po. When the timer 12 reaches a preset time, the valve 13 is opened so that the pressure of the hydraulic cylinder 6 begins to fall.

Title: Displacement sensor and ic for the same
Inventor: NAKAJIMA TOYOHEI
IPC: H01L27/22
Filed: 1989-04-27
Abstract: PURPOSE:To obtain an output which linearly changes in proportion to the quantity of a displacement and obtain the same output voltage for the same quantity of the displacement by arranging two magnetic pole planes in a plane parallel to a semiconductor flake forming a magneto-electric transducer housed in an IC. CONSTITUTION:When an object whose displacement is to be detected and which is connected to a link arm 9 reciprocates in a direction shown by an arrow A, the link arm 9 rocks about an axis 9a while following a reciprocation. A rocking thus obtained is converted to the reciprocating motion of a slider 6 via rod 6a and the slider 6 slides in a housing 8. Thus a relative positions of a Hall IC 5 fixed to the housing 8 via a substrate 12 and the slider 6 change. When the relative positions change, the density of magnetic flux crossing a current supplied to the Hall IC 5, namely, the one effective to generate a voltage due to a Hall effect, in the magnetic flux formed by magnets 11a and 11b changes. As a result, a voltage outputted from the Hall IC 5 due to the Hall effect changes.

Title: Production of silica sol
Inventor: TAKEUCHI TETSUHIKO
IPC: C01B33/148
Filed: 1988-04-28
Abstract: PURPOSE:To easily obtain a silica sol having high concentration and excellent dispersibility by hydrolyzing an alkyl silicate with a basic catalyst and concentrating the resultant silica dispersion under irradiation of ultrasonic wave, thereby preventing the aggregation of silica particles. CONSTITUTION:An alkyl silicate (e.g. ethyl silicate) is added to a solvent composed of an alcohol and water and is hydrolyzed with a basic catalyst (e.g. ammonia water) to obtain silica particles. The obtained silica dispersion is concentrated under irradiation of ultrasonic wave by heating under reduced pressure or by ultrafiltration. A high-concentration silica sol can be produced by this process without varying the particle size distribution of the fine silica particles before and after the concentration. The obtained silica sol having high concentration is suitable as a production raw material for glass by sol-gel process, carrier for various reaction catalysts, etc.
