IPC: H01L21/822
Filed: 1990-09-05
Abstract: PURPOSE:To conduct a high speed test efficiently by a method wherein a nullifying circuit is provided to detect whether an internal voltage is a high testing voltage or not and, if it is, to nullify the voltage drop operation of a voltage drop circuit. CONSTITUTION:If a high testing voltage higher than a predetermined voltage is applied to a pad 12 in order to conduct a high speed test and the like, the voltage drop operation of a voltage drop circuit 11 is nullified by an activation signal phi outputted from a nullifying circuit 14. Therefore, the high testing voltage is applied to an internal circuit 13 to conduct the high speed test and the like. On the other hand, if a normal external voltage lower than the predetermined voltage for the high testing voltage is applied to the pad 12, the nullifying circuit 14 does not output the activation signal phi. As a result, the voltage drop circuit makes the external voltage Vcc normal and applies it to the internal circuit 13. With this constitution, the high speed test can be conducted efficiently.

Filed: 1993-08-31
Abstract: PURPOSE: To safely protect computer facilitates by confirming respective responses as the functions of respective challenges and interrupting data connection, when confirmation is indicated that one of the responses is not confirmed. CONSTITUTION: When an ID number of a transmission modem is received, a CPU 210 processes a correspondent data cryptographic key from a key list 221. Afterwards, the CPU 210 generates random numbers as challenges and transmits them to an oscillation modem. The oscillation modem enciphers the challenges, generates responses, and returns them to a modem 200. When the decoded response does not match the challenge, the CPU 210 transmits 'access refused' and interrupts data connection. When the decoded response matches the challenge, the CPU 210 does not connect data but checks whether or not the challenge of recertification is completed. When the challenge of re- certification is completed, the transfer of data information is enabled between the modem 200 and the oscillation modem.

Title: Synthetic resin coated roll
Inventor: SAKAI TAKASHI
IPC: B32B15/08
Filed: 1983-12-19
Abstract: PURPOSE:To make it possible to provide desired surface characteristics to a roll having a metallic roll body covered, on the outer surface thereof, with a synthetic resin layer, by forming the synthetic resin layer with a uniform polyamide layer having therein fine pores in a predetermined porosity range. CONSTITUTION:A polyamide synthetic resin layer 3 having therein fine pores 5 uniformly distributed thereover is covered on the outer surface 2 of a metallic roll body 1 which is subjected to satin finish. The porosity of this synthetic resin layer is in a range of 2 to 25%, which is effective in changing the surface characteristics such as, for example, electrical resistance, adhesion, heat transfer coefficient, etc. However, an excessive porosity causes the mechanical strength of the cover layer to be lowered, and therefore the porosity range from 2 to 25% is suitable. At first the synthetic resin is formed such that the diameter of the pores is less than 0.5mu at muximum, but 0.1-3mu on an average, and the thickness of the layer is 0.2-15mm.. Then the outer surface of the layer is ground so that the layer has a thickness (d) of 0.08-10mm., preferably 0.20-7mm., having uniform pore distribution.
