Filed: 1992-06-05
Abstract: PURPOSE: To implement introducing operation more rapidly than ever without deterioration of the sterilized nature of an object in an air of a separated chamber, in a device for introducing a sterile object into a clean air kept at excessive pressure. CONSTITUTION: A separated chamber kept at an excessive pressure is provided with at least 1 device comprising an inclined guide tube 38 which has a bottom end connecting through with the separated chamber via a door 18 usually closed. An object to be introduced, which is protected by a sealing bag is placed on a platform 40 facing the top end of the guide tube 38. The platform and the inside of the guide tube are cleaned by a clean air coming from a ventilation box. As a result, sterile nature of the object can be maintained even when the sealed bag is cut at the platform.

Title: Waveform converter
Inventor: SHIGEMATSU TOMOHISA
IPC: H03K5/1532
Filed: 1981-09-14
Abstract: PURPOSE:To realize the miniaturization for a waveform converter, by using a clocked inverter consisting of an N or P channel type MOSFET that uses a clock pulse synchronous with the rise of an input signal or the input signal as a gate input for a delaying circuit. CONSTITUTION:Clocked inverters 33 and 39 consisting of an N or P channel type MOSFET that uses a clock pulse cp synchronous with an input signal Si as a gate input are used as the delaying circuits of a waveform converter. When the signal Si has a fluctuation, the output Si' is delayed by an extent equivalent to the width of the pulse cp through the inverter 33. Accordingly, pulse outputs P1-P4 corresponding to the fluctuation of the signal Si are obtained by making the signal Si and the output Si' pass through a NAND gate 34, an NOR gate 35 plus inverters 36 and 37, respectively. In such way, an integrated circuit can be easily obtained since no capacitor is used in a delaying circuit. Thus a waveform converter can be miniaturized.
