Title: Inspector for equipment with sound or vibration
Inventor: TAKENAKA TOSHIO
IPC: G01M99/00
Filed: 1982-11-26
Abstract: PURPOSE:To enable accurate detection of deficiency even for an intermittent defective component where the frequency spectrum from an object to be inspected varies instantaneously by determining the variation with time of the frequency spectrum in terms of frequency components of the spectrum to be compared with a reference value. CONSTITUTION:A noise of a motor 1 is taken into a frequency analyzer 10 through a microphone 2 and an amplifier 3 to apply a spectrum A to a standard deviation computing unit 20 corresponding to the noise. The computing unit 20 determine a standard deviation within a fixed time in terms of frequency components of the spectrum A and a standard deviation vector E in terms of frequency components is applied to a differential device 11. At the same time, a signal (a reference vector F) of a reference memory 12a is applied to the differential device 11 with which a deviation obtained by subtracting the reference vector F from the standard deviation vector E is applied to an totalizer 14 through a non-negative circuit 21. Deviation portions are totalized with an totalizer 14 which provides a total sum G to a discriminator 15. The discriminator 15 compares the total sum G with the set value and judges that the motor works well when the total sum G is below the set value. It judges that the motor is poor in its nature when it exceeds the set value.

Title: Manufacture of barium ferrite magnet
Inventor: KOGO MASANORI
IPC: C01G49/00
Filed: 1990-08-06
Abstract: PURPOSE:To remarkably simplify a working process and reduce cost, by mixing, as main material, iron oxide for ferrite and barium carbonate, performing granulation by using PVA as binder, performing molding with necessary green density, eliminating PVA at a temperature range of 180-450 deg.C in a baking process, and obtaining a porous state. CONSTITUTION:Iron oxide for general ferrite and barium carbonate are used as starting material; BaO and Fe2O3 are mixed by setting the composition ratio as 1:5.3; PVA of 1.5 wt.% as binder is added to the starting material of 100 wt.%; green density is set as 2.79 g/m<3> and molding is performed at a pressure of 2.5Angstrom /m<3>. In the next baking process, 180-450 deg.C is set as a gradually rising temperature (4 deg.C/min is set as the upper limit), thereby completely eliminating the binder. Then carbonic acid gas generated in a temperature range of 450-800 deg.C smoothly runs away. As a result, fracture, crack and deformation are not generated independently of the rate of temperature rise in the subsequent process.

Title: Piezoelectric transformer circuit device
Inventor: KIKUCHI ICHIRO
IPC: H02M7/48
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To detect total loading condition of a piezoelectric transformer to enhance the breakdown preventing property of a drive circuit by detecting a feedback voltage in proportion to an output voltage. SOLUTION: A feedback voltage Vf is inputted as a detection voltage Vs to a comparator IC2 with a rectifying/smoothing circuit 3 for the purpose of comparison with the reference voltage Vr. Under the normal output condition, the detected voltage Vs becomes higher than the reference voltage Vr. Under the irregular output voltage condition, an output of the piezoelectric transformer is lowered to drop the feedback voltage Vf and detected voltage Vs. When the detected Vs becomes lower than the reference voltage Vr, the comparator IC2 outputs the H level to turn on a feedback voltage cutoff transistor Tr4, cut off an output of an oscillating circuit 8 because it stops the operation. Thereby, the cut-off condition of an output can be held.  In this case, the H level is outputted to a terminal 5, a control output transistor Tr6 turns on, the L level is outputted to a terminal 6, a control transistor Tr7 turns off and a terminal 7 is in the high impedance condition.
