Title: Sonar system using adaptive beam former
Inventor: NISHIMURA HIROSHI
IPC: G01S15/89
Filed: 1984-05-30
Abstract: PURPOSE:To prevent degrading of characteristic and generation of noises by forming two beams close to a target direction estimated value to eliminate the discontinuity in the calculation of adaptive coefficient due to changeover in the direction of beam main axis due to time change in the target direction. CONSTITUTION:First and second estimated direction discrete value converters 70 and 71 and a multiplexer 80 are added to a sonar comprising an adaptive beam former (ABF), nonadptive waiting beam former (waiting CBF) and the like. The second converter 71 selects and outputs the direction alpham from two values - the discrete value alphal the closet to the target direction estimated value alpha which is outputted from the first converter 70 and the target direction estimated value alpha which is outputted from a target direction tracker 30. With such an arrangement, the calculation of coefficients of a variable filter for both directions alphal and alpham with a coefficient counter 43 can be done continuously regardless of switching in the direction of main axis of beam. This eliminates errors in the calculation to prevent the degrading of the ABF characteristic while removing noises from the beam output.

Filed: 1993-05-10
Abstract: PURPOSE:To provide a compact fuel cell by producing a reducing agent with fuel decomposed electrochemically, and thereby generating electricity with the help of the reducing agent. CONSTITUTION:In a reducing agent producing means 200, water or steam is supplied to a fuel use electrode 202 together with methanol acting as fuel, and voltage is applied in such a way that electrons are extracted out of the electrode 202 through an external circuit 204. As a result, hydrogen ions produced out of the electrode 202, pass through a cation exchange film, so that hydrogen can be selectively produced at the side of a counter electrode 203. In this case, almost no CO is produced by this reaction. Hydrogen produced by the means 200 is supplied to a fuel use electrode 302, and oxygen is also supplied to a counter electrode 303 from the outside. An external load circuit 304 is connected to the electrodes 302 and 303 through separators 306 and 307. The aforesaid connection permits current to flow at the electrode 302 in such a way that electrons are extracted out of the electrode 302, subsequently electrochemical reaction takes place in the electrodes 302 and 303 respectively so as to allow the electrode 302 to be turned out a negative electrode, and also allow the electrode 303 to be turned out a positive electrode, so that electricity can thereby be taken outside.

Title: Semiconductor strain gauge type absolute pressure sensor
Inventor: SUZUKI KIYOMITSU
IPC: G01L9/00
Filed: 1978-09-06
Abstract: PURPOSE: To improve the airtightness of a semiconductor strain gauge type absolute pressure sensor by constructing respective members by materials having similar thermal expansion coefficients.  
     CONSTITUTION: A glass stem 1 is formed by glass member having similar thermal expansion coefficient to that of a silicon member 5 forming a semiconductor strain gauge. A pressure intake pipe 3 and leads 4 having equivalent thermal expansion coefficient are sealed in the glass stem 1, which is coated by the member 5 with a cap 10 having similar thermal expansion coefficient to that of the galss stem 1 and secured thereto. Since the respective members have similar thermal expansion coefficients, the adhered portion between the respective members is not thermally strained to a crack but retains preferable airtightness. Pressure to be measured is introduced through the pipe 3 into a diaphragm chamber 7 of the member 5 to allow a pressure-sensitive diaphragm 6 to be deformed in response to the difference between the pressure to be measured and the standard vacuum pressure in the chamber 11. This deformation is picked up by a lead 4 as electric amounts.

Title: Defective inspection of closed container or the like
Inventor: MURAKAMI YOSHINORI
IPC: G01M3/02
Filed: 1987-04-30
Abstract: PURPOSE:To enable a defective inspection to be conducted on a closed container or the like by putting a packed object, such as the closed container, to be inspected in a chamber, reducing pressure by sucking the inside of the chamber and optically observing the condition of air current flow blowout from the packed object to be inspected by means of shadow-graph method or the like. CONSTITUTION:A light transmitting windows 2 are arranged in both side surfaces of an airtight chamber 1 and concave mirrors 3 and 4 are provided on both sides of the chamber 1. The mirror 3 is projected with rays of light from a point light source 5 and projects parallel rays to the chamber 1. The parallel rays are received and reflected by the mirror 4 opposing to the mirror 3 and received by a video camera 6 or the like whereby the condition of change in the density of the object 9 to be inspected in the chamber 1 is observed. That is, the packed object 9 to be inspected is put in the chamber 1 and the inside of the chamber 1 is rapidly sucked to a prescribed vacuum condition by a vacuum pump 14 or the like. When the packed object 9 has a pin hole or the like, a gas or the like in the packed object 9 is blown out and a density difference is generated in the gas around the packed object 9. Therefore, observed images before and after a suction for a pressure reduction are different from each other and it can be judged that the packed object 9 is defective. Further, when an image processing is conducted by a CPU 6, an automatic selection can be conducted.

Title: Variable gap eccentric motor
Inventor: KIYOFUJI YOSHIO
IPC: H02K41/06
Filed: 1991-04-13
Abstract: PURPOSE:To calm operation sound by interposing an elastic member between the projection projected from a needle and the inside periphery of an dislocation regulating hole. CONSTITUTION:A needle rocks eccentrically while rotating accompanying the shifting of a magnetic field. When such a needle 34 rocks eccentrically while rotating, in each position, with the length of the gap between a stator 22 and an inner gear 40 as a diameter, the inner gear 32 always engages partially with the outer gear 36 of the inner gear 40 installed inside, and the place of its engagement can be shifted in order along the periphery of the gear 40. Though each pin 46 and 48 projecting from the needle 34 performs circular motion with the length approximately equivalent to the difference between the inside diameter of a stator for an electric field and the outside diameter of the needle 34 as a diameter, resisting the elastic forces of elastic members 51 and 53, it does not cause contact directly with the inside periphery. Hereby, operation sound can be calmed remarkably.

Title: Duplicate image recorder
Inventor: FURUTA HIDEYA
IPC: G03G15/01
Filed: 1989-04-27
Abstract: PURPOSE:To efficiently maintain the attracting condition of a reciprocating means and a recording sheet by transferring the recording sheet during outgoing carrying, and then, reattracting the recording sheet to the reciprocating means by means of a reattracting means while return-carrying is carried out. CONSTITUTION:The recorder is provided with the reattracting means 234 and 236 reattracting the recording sheet to the reciprocating means 231. The recording sheet is transferred during the outgoing carrying, and the reattracting means 234 and 236 reattract the recording sheet to the reciprocating means 231 while the return-carrying is carried out. Thus, if attracting power between the reciprocating means 231 and the recording sheet drops after the transfer is performed, the reattraction by the reattracting means 234 and 236 increase its attracting power. Consequently, the attracting condition between the reciprocating means 231 and the recording sheet is efficiently maintained, and the occurrences of image dislocation and irregularities in transferring are prevented.
