IPC: F04C29/06
Filed: 1992-03-05
Abstract: PURPOSE:To reduce leakage from a compression space while restraining the increase of inputs and noise, etc., by interposing a thin stripe on the inner peripheral surface of a cylinder room, and forming an oil layer between the stripe and the inner peripheral surface of the cylinder room. CONSTITUTION:A thin stripe 71 of thickness (mu) on the order of tens is interposed which makes contact with the outer peripheral surface of a roller 3 near a proximity portion between the inner peripheral surface of a cylinder room 1 and the outer peripheral surface of the roller 3 and extends along the inner peripheral surface of the cylinder room 1. An oil layer 81 for retaining oil entering via a space extending in the direction of height between the stripe 71 and the cylinder room 1 is formed between the stripe 71 and the inner peripheral surface of the cylinder room 1. Therefore, when the inner peripheral surface of the stripe 71 makes contact with the outer peripheral surface of the roller 3 near the proximity portion between the roller 3 and the cylinder room 1 as the roller 3 revolves, the oil layer 81 is pressed and removes a space secured between the cylinder room 1 and the roller 3, thereby preventing leakage from a compression space 5 into a suction space 4. Also, load troque can be prevented from increasing in excess and noise and vibration can be reduced.

Title: Telecommunication safety device for public exchange telephone circuit network
Inventor: POLLARD ALAN JONATHAN
IPC: G06F21/34
Filed: 1986-03-07
Abstract: A telecommunications security device for use on the public switch telephone network includes a first (10) and a second (11) security unit each arranged to be inserted into the telephone line (12) adjacent a user device. The units are identical and therefore either can act as a central unit for example for a computer access port with the other providing one of a set of remote units. Each unit includes a separable security key (21A) with all the keys having a memory (212) storing identical information. The information stored includes a plurality of pairs of random signals one of each pair providing a request signal and the other the security code. The central unit on receipt of a telephone call provides a signal requesting an ID code from the remote unit and on receipt of the ID code issues from one of the pairs the security code request signal. On matching the received code with the expected code a transmission gate (30) is opened. The pairs are used in turn until all of the pairs have been used as shown by an indicator (341). The keys (21A) can be removed and the memory (212) re-written with fresh pairs of codes. The key includes a security logic device (211) which acts to seal the key from reading after it has been written, to allow reading after receipt of a command signal but to indicate on receipt of a second command that the first command has been received and thus the key has been read.

Abstract: PURPOSE:To prevent the deterioration of image by providing level correcting means before and after a synthesizing means which synthesizes outputs of channels into a series signal, eliminating the level difference between channels, and adapting the output to a required level of an A/D converter. CONSTITUTION:The DC level of the dark output part of an odd picture element signal 101a is clamped at about 0V by a clamp amplifier 104a. An even picture element signal 101b is set to such reference level by a clamp amplifier 104b and a voltage control circuit 109, to which data is set by a CPU, that the offset level difference between odd and even picture element signals is eliminated. Both signals are multiplexed to a series picture element signal of one line by a multiplexer 105, and this signal has the white level set to a maximum value of the dynamic range of an A/D converter 108 by a variable amplifier 106 and has the dark level set to a minimum range by a clamp amplifier 107. Thus, the level difference between outputs is eliminated to adapt levels to the range of the A/D converter, thereby preventing the deterioration of image.
