Abstract: PURPOSE:To increase an adhesive strength between a frame and an armor plate and thereby ensure that no damage occurs, even if these components become curved by providing recessed parts on the surface where the armor plate is bonded of the frame. CONSTITUTION:A multi-functional IC card 1 consists of a frame 3 with recessed parts 31. When bonding an armor panel 2 to the frame 3, an adhesive 32 is applied to the surface of the frame 3, and further, each recessed part 31 is filled with the adhesive 32. If the adhesive 32 is completely applied, an armor panel is bonded to the frame 3 by the armor panel 2 is forced to come in contact with the frame 3 until the adhesive becomes cured. Subsequently, the adhesive becomes thick at each recessed part provided at the frame 3, the adhesive strength increases. In addition, even if the multi-functional card 1 becomes curved by an external force, the adhesive 32 filled in the recessed part 31 and cured becomes deformed due to a shearing effect, resulting in the absorption of a stress. Therefore, there is no fear that the armor panel might peel off the frame 3 and drop down due to the curving that occurs resultantly.

Title: Dc-dc converter
Inventor: TSUCHIYA KEIJI
IPC: H02M3/28
Filed: 1987-12-03
Abstract: PURPOSE:To perform a good starting at the time of switching a power ON and to make it unnecessary to use elements having characteristic more excellent than required by turning OFF a Zener diode and preventing a protection circuit from operating for a specified period at the time of switching the power ON. CONSTITUTION:When a power switch 2 is turned ON, a transistor 16 is turned ON for a specified period of time determined by resistors 18, 19 and a capacitor 20. During the period of time, a parallel circuit of resistors 14 and 17 is connected between both ends of a load current sensing capacitor 13, and accordingly the resistance value of the resistor 14 is reduced by half. Therefore, voltage at a node of the resistor 14 and a Zener diode during that period of time becomes smaller than a set voltage under the influence of an internal impedance of a power source viewed from the capacitor 13. Further the Zener diode 15 is not turned ON, and the protection circuit does not operate. Therefore, even if a load current increases during the starting, the protection circuit does not operate and it is possible to start a DC-DC converter.

Abstract: PURPOSE:To make the surface of a paste applied glass substrate smoother by vibrating the glass plate after applying the paste prepared by kneading raw material powder mixed with a thickener to the surface of the glass plate. CONSTITUTION:A layer is formed on a glass substrate 1 by applying paste prepared by kneading fine CdS powder mixed with a flux composed of CdCl2 and thickener composed of PG to the surface of the substrate 1. Ultrasonic waves 28kHz in frequency are given to the substrate 1 for five seconds by bringing the horn of an ultrasonic oscillator using a piezoelectric vibrator into contact with the outer end face of the substrate 1. As a result, recessing and projecting sections formed on the surface of the paste in the form of the mesh of a screen are reduced as compared with the surface before vibrating the substrate 1 and, at the same time, bubbles which may cause pinholes are removed from the paste. Therefore, the surface of the paste can be smoothed. In addition, after forming a sintered CdTe layer 3 on a sintered CdS layer 2, a carbon collecting electrode layer 4 is formed on the layer 3. Finally, a group II-VI compound solar battery is formed by respectively forming a positive electrode terminal 5 and negative electrode terminal 6 on the layers 4 and 2.

Filed: 1996-11-19
Abstract: PROBLEM TO BE SOLVED: To provide a ferroelectric memory provided with proper capacitors corresponding to an atual read time, and capable of performing a read-out operation at high speed and reducing power consumption. SOLUTION: When the voltage corresponding to the detection limitation of a sense amplifier AMP1 is defined as 0.8V, an impression time t (=2.5nsec) whose maximum value of a difference voltage ΔV is about 0.87 is selected. Moreover, the capacitance C (≈1.25pF) of a capacitor Cb for load applying the maximum value of the difference voltage ΔV in the impression time t=1.25 nsec is determined. The impression time tp of a voltage Vp for readout is made to be 2.5nsec similarly to the imression time (t) of a voltage Vd for characteristic determination. The time required for a rewriting is also shortened by reducing the impression time tp of the voltage Vp for readout. Thus, a time from a readout to the rewriting is more shortened. Moreover, power consumption is reduced.
