Title: Dry-type capacitor
Inventor: UNAMI KIYOSHI
IPC: H01G4/18
Filed: 1990-02-08
Abstract: PURPOSE:To obtain a capacitor whose dielectric loss tangent is low and whose potential gradient is high by a method wherein a silane coupling agent is contained in a capacitor element. CONSTITUTION:When voltage dependence values of a dielectric loss tangent at 70 deg.C are compared, the dielectric loss tangent at 700V of a capacitor H containing a silane coupling agent in a capacitor element is a value of about 1/3 of that of a conventional capacitor I. The silane coupling agent is an organic silicon compound which is provided with a reaction group chemically bonded to an inorganic material and with a reaction group chemically bonded to an organic material. As a result, it captures impurities which have a bad influence on a dielectric loss tangent existing on the surface of a film and on the surface of an electrode. Thereby, it is possible to obtain a capacitor whose dielectric loss tangent at a high temperature is low and whose potential gradient is high so as to be used at a high voltage.

Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To reduce an occurrence of noise by a method wherein an extremity end side of a burner structure single body, is provided with gas flowing-out ports communicated with negative pressure sections generated by a discharged gas flow produced from a combustion space at both front and rear extremity end surfaces of the combustion wall member, and secondary combustion air is supplied to the rear surface side of the discharged gas discharging side negative space. SOLUTION: An extremity end surface 30 of a combustion wall 6 is provided with a gas flowing-out port 201. This gas flowing-out port 201 is a slit-like opening arranged in a side-by-side direction of a flame port 8 set at a right angle in respect to a burner structure single body 4 and a combustion flame forming direction. Secondary combustion air is supplied by a suction fan F through a gas flowing-out port 201 communicated and connected to a discharged gas discharging negative pressure space 200 located at the extremity end side of the burner structure single body 4 and acting as a negative pressure section induced by the discharged gas flow discharged out of the combustion space 3. Accordingly, such a gas flow may prevent an eddy flow from being formed at the negative pressure section and restrict occurrence of noise.

Title: Rotating speed detection circuit for brushless motor
Inventor: TORISAWA AKIRA
IPC: H02P6/08
Filed: 1981-02-27
Abstract: PURPOSE:To sense correct rotor rotating speed signal with a simple constitution by taking out starting voltage from the middle point of the star-connected armature coils of a brushless motor. CONSTITUTION:Armature coils 1a-1c are star-connected for a 3-phase brushless motor. The driving circuit 5 senses rotational position of the permanent magnet rotor with a Hall element, driving current is commutated by changing over successively through each coil of the tester. The potential VN at the neutral point of start-connected armature coils is the sum of the inverse electro-motive force of the coil on the earth side and the voltage drop developed in a winding coil by the above mentioned commuted current. The potential VN, therefore, changes for each change-over interval, and the potential VN of the neutral point  has amplitude with the center at 1/2 of the voltage of the power source. The  amplitude is proportional to the speed, and its wave shape repeats itself 6 times  for one rotor rotation, and the voltage is compared with the 1/2 of the electric source voltage to issue speed signal at a comparator 3. Next, at the control circuit 4, difference from the target value is detected to control speed.
