Title: Multilayer wiring board
Inventor: ISHIDA HISASHI
IPC: H05K3/46
Filed: 1990-05-18
Abstract: PURPOSE:To avoid effect of a cross talk noise which is generated from a signal of an adjacent pattern by enclosing a peripheral part with a ground wiring pattern and by forming a clock pattern in electromagnetically shielding structure. CONSTITUTION:A clock pattern 11 is formed to be completely enclosed with a ground wiring pattern 12 in a signal layer of a multilayer wiring substrate. Via holes 14 for connecting the ground wiring pattern 12 to either of ground layers existing on both sides of the signal layer are arranged at fixed intervals. That is, since the clock pattern is electromagnetically shielded completely by the ground wiring pattern even if an adjacent pattern is running in parallel thereto, connection between patterns is not generated and mutual capacitance and mutual inductance between patterns do not exist. Thereby, it is possible to completely avoid effect of a cross talk noise which is generated from a signal of an adjacent pattern.

IPC: G01R33/09
Filed: 1990-05-18
Abstract: PURPOSE:To improve the hysteresis characteristic of an R-H curve by giving a magnetoresistance element a structure wherein an amorphous soft magnetic thin film is laminated on the surface of a ferromagnetic substance thin film having a magneto-resistance effect, with a titanium thin film interlaid as a medium for magnetic coupling. CONSTITUTION:When a magnetic field is generated by a current flowing (in the direction of a broken-line arrow A) through a ferromagnetic substance thin film 1 in the lowermost layer, an amorphous thin film 3 in the uppermost layer is magnetized in accordance with that. The magnetization of the amorphous thin film 3 is transmitted to the ferromagnetic substance thin film 3 (as shown by arrows B) through an intermediate Ti thin film. As the result, a state wherein a bias magnetic field is impressed on the ferromagnetic substance thin film 1 itself in accordance with the current (sense current) flowing through the ferromagnetic substance thin film 1 is obtained, and it acts so that the hysteresis of an R-H curve of the ferromagnetic substance thin film 1 is eliminated.

Abstract: PURPOSE:To extend the service life of electric components, reduce the number of components required and hence reduce manufacture cost by installing integrally a relay, which controls both an upper heater and a lower heater for an electric oven or a control transformer to a control section of a high frequency heating device. CONSTITUTION:A relay 15b, which controls an upper heater 2 and a lower heater 3 for an electric oven or a control transformer 16, which supplies specified voltage to the electric oven, is installed to a control section 8 of a microwave heating device main body 4, which makes it possible to reduce a rise in the temperature of each component due to the heat of the heaters of the electric oven, and improve the reliability and durability of the control components or device. Furthermore, since the control components are integrally installed, it is possible to use the control components more efficiently by driving a cooling fan 20, which is fixedly installed on the high frequency heating device. Therefore, low temperature rated control components are applicable and advantageous in terms of cost. In fact, this construction eliminates the need for a cover which insulates and protects the relay 15b or the control transformer 16 from the heat of the heaters or a rubber spacer. Therefore, this construction is cost- advantageous.

Title: Induction motor type electric rolling stock control system
Inventor: TSUBOI TAKASHI
IPC: B60L9/18
Filed: 1981-08-18
Abstract: PURPOSE:To effectively perform the starting of an electric rolling stock on an ascending gradient by detecting that the backward speed of the rolling stock exceeds the prescribed value and switching the winding of an induction motor to a DC excitation. CONSTITUTION:The fact that the speed of an electric rolling stock exceeds the prescribed value is detected by a backward movement detector 61 and a speed comparator 62 of the rolling stock, and the frequency instruction switch 63 of an inverter 2 applies an instruction for setting the output frequency fF=0 of an inverter to the inverter 2. Thus, an oscillator contained in the inverter 2 stops oscillating, and the inverter 2 is controlled to flow a DC current to the coil  of an induction motor 3. In this manner, even if the rolling stock once goes backward when the rolling stock starts on an ascending slope, the torque of the induction motor is not remarkably reduced, thereby enabling to smoothly oscillate the oscillator.
