Title: Resistance measuring electrode for sensor
Inventor: TSUCHIYA SHIGEKI
IPC: G01K7/16
Filed: 1984-03-21
Abstract: PURPOSE:To obtain an electrode excellent in mass productivity, by alternately laminating insulating layers and conductor layers and utilizing the cross-sectional area of the laminate to use the conductor layers as a resistance measuring electrode for a sensor. CONSTITUTION:A large number of conductor layers 5 and insulating layers 4 are alternately stacked. This process can be performed by utilizing a green sheet and thick film printing technique. Because the gaps between electrodes are determined by the thickness of each insulating layer 4, each gap can be reduced to about 10mum. Thereafter, right and left parts are cut and the cross-sectional area exposed by cutting is metallized to connect the conductor layers and a pair of comb shaped electrodes are formed while leads are attached to the metallized parts 6. Because of a structure only cutting the laminate of conductors and insulators as mentioned above, mass productivity is excellent.

Title: Method for measuring crystal particle size of steel plate
Inventor: ISHIHARA MICHIAKI
IPC: G01N15/02
Filed: 1987-03-06
Abstract: PURPOSE:To determine the crystal particle size of a steel plate, by dividing a Barkhausen noise signal by the power function of a permeability signal on the basis of the difference in steel plate speed dependence between the signal due to the Barkhausen noise generated at the time of the magnetization of the stele plate and the signal caused by permeability. CONSTITUTION:An electromagnet 2 and a sensor 3 are arranged so as to hold a running steel plate 1 therebetween and an AC current is allowed to flow to the electromagnet 2. When the output of the sensor 3 is allowed to pass through a low-pass filter (LPF) 6, a signal S1 is caused by permeability. When said output is allowed to pass through a high-pass filter (HPF), a signal S2 is caused by Barkhausen noise. The signals S1, S2 are respectively operationally processed by an operator 11 through a voltmeter 8, an amplifier 9 and a counter 10 and transmitted flux quantity Bt is raised to m-th power to divide the Barkhausen noise BNV. By this method, the particle size number dependence possessed by both factors can be still more developed and, when an m-value is selected, the moving speed dependence of the steel plate becomes unchangeable and, even when the material quality of the steel plate is altered, the alteration of the m-value is made unnecessary. By this constitution, a crystal particle size can be continuously measured on-line in a steel plate manufacturing process in a non- destructive manner.

IPC: H02M5/12
Filed: 1999-01-22
Abstract: PROBLEM TO BE SOLVED: To reduce the size of an AC transformer by providing a polarity inversion circuit on an input line and inverting the winding current at high speed so that the flux has no chance of growing significantly thereby reducing the volume of a magnetic body. SOLUTION: A high frequency circuit comprises a polarity switching high frequency switch 2 and a high speed reswitching switch 4 provided, respectively, at the input and output so that the switch elements are bi-directional. When the switch element is driven in synchronism with the input side, polarity is reinverted to reproduce the original low frequency component. Consequently, the voltage is converted while sustaining the waveform accurately and bidirectivity of current flow is sustained automatically without requiring any control and the size of a power converter can be reduced as required depending on the switching frequency.

Abstract: PURPOSE:To effectively form a soldering or connecting part of a semiconductor device by forming a groove at the periphery of a cavity of a substrate, or forming a rugged part on a lead terminal, thereby preventing resin for protecting a chip and a wire from flowing out to the soldering or connecting part forming region on the substrate. CONSTITUTION:A groove 8 is formed at the periphery of a cavity 7. The width of the groove 8 is formed in the width capable of readily flowing dropped rain into the groove and in the depth deeper than the depth of the cavity 7. Since the resin dropped on a chip 2 is always filled in the groove 8 by forming such a groove 8, the resin is prevented from expanding and flowing to the outer edge. Since the groove 8 is formed simultaneously upon forming of the cavity 7, excess steps are not required to form the groove 8. A rugged part may be formed on the part of a lead terminal which is positioned on the part to be formed with a groove instead of the formation of the groove 8.
