Patent JP-H07150126-A (JP)
Title: Flame-retardant adhesive
Inventor: TAKAOKA SEIICHI
IPC: H05K3/38
Filed: 1993-11-30
Abstract: PURPOSE:To improve flame retardancy and heat resistance by compounding a thermoplastic high-molecular weight polyester with a brominated phosphoric ester and an inorg. filler. CONSTITUTION:100 pts.wt. thermoplastic high-molecular weight polyester is compounded with 20-150 pts.wt. brominated phosphoric ester and 1-50 pts.wt. inorg. filler. The polyester is produced by the polycondensation of a dicarboxylic acid (e.g. terephthalic acid) with a diol (e.g. ethylene glycol) and has a mol.wt. of 10,000-30,000. An example of the phosphoric ester is tris(dibromophenyl) phosphate. An example of the filler is calcium carbonate, pref. having an average particle size of about 1mum or lower. Regardless of the shape of the adhesive, its flame retardance and heat resistance are improved by the exposure to a radiation such as an electron beam or gamma-ray. The dose of the radiation is usually 50-300kGy, though varied by various factors.

Title: Memory card
Inventor: KOBAYASHI ICHIRO
IPC: G06K19/073
Filed: 1991-11-15
Abstract: PURPOSE:To reduce the malfunction of a RAM in a memory card against the fluctuation of an external power source by selecting high potential connected to the control signal line of a memory card via a pull-up resistor from plural power source systems in the memory card. CONSTITUTION:The control signal line 7 of the memory card is connected to an element 9 which switches the external power source 1 and an internal power source 6 via the pull-up resistor 8. The power source 9 for pull-up outputs an external source voltage as the voltage for control signal pull-up when the external power source 1 is applied. Also, when no external power source 1 is applied, the power source 9 outputs an internal source voltage as the voltage for control signal pull-up. Thereby, it is possible to reduce the follow-up of potential when no card control signal is directly added on the outside of the memory card, and to reduce the malfunction of the RAM in the memory card.

Filed: 1992-11-12
Abstract: PURPOSE:To enable the optimization due to a semiconductor testing device itself within a short time by determining optimum characteristics on the basis of the output voltage value of an element to be tested by a multiple reflection preventing circuit. CONSTITUTION:A timing signal 1a and a test pattern 2a are synthesized and a test waveform 6a is applied to an element 12 to be tested. The response signal 12a of the element 12 is digitally converted by an analogue comparator 5 and, thereafter, the digital value and an expected value 2b are compared at the time shown by the timing signal 1b. At this time, a multiple reflection preventing circuit 7 is provided in order to enhance the confirmation accuracy of a response time in a test. That is, at the point of time when the waveform 12a of the element 12 reaches the circuit 7 and the reflection waveform 12b reaches the element 12, the waveform 12a becomes voltage VOH and, at the point of time when the waveform 12a again reaches the circuit 7, the waveform 12b also becomes voltage VOH. At this time, the potential of a transmission line becomes equal to VOH and, thereafter, no reflection phenomenon is generated to obtain constant potential. Therefore, a place of H or less is not generated in the element 12 at the input terminal of the comparator 5 and accurate rising can be measured. By this constitution, the characteristics of the circuit 7 can be optimized.
