Abstract: PURPOSE:To prevent an irregular reflection of light by foams without requiring a vacuum pump, etc., by a simple operation, by providing a liquid discharge tube of air in a balloon and a tube, so that it can be removed completely. CONSTITUTION:A flexible cable 1 of an endoscope is inserted into an organ. A balloon 3 is in a contracted state, and when it reaches an image pickup part A, a transparent liquid J is fed to a tube 7 from a cylinder F, advances through a transmitting part, goes into the balloon 3, and the balloon is expanded by the transparent liquid. A liquid discharge valve G is opened in order to exhaust the air of the balloon 3, etc. The liquid expands the balloon 3, passes through a liquid discharge tube 8, and is discharged through the valve G. Fine foams in the tube and the balloon are discharged to the outside from the valve G together with a flow of the liquid. When the residual air is gone, the valve G is closed. In this way, the air in the tube and the balloon can be exhausted completely.

Title: Burst optical reception circuit
Inventor: YANAGISAWA HIROKI
IPC: H04B10/60
Filed: 1995-03-17
Abstract: PURPOSE: To ensure the correct offset compensation even when the offset level varies for every burst. CONSTITUTION: A control signal that is synchronous with the guard time (non- signal area set between burst signals) of a burst optical signal is inputted to a peak value detection circuit 17 which detects the peak value of an anti-phase signal from a reset signal control circuit 19. When the control signal is inputted, the circuit 17 discharges its holding peak voltage. Therefore, the input current of a preamplifier 12 is compensated by an operational amplifier 18 in response to the offset variance if caused for every burst optical signal. As a result, the correct reproduction of signals is always ensured despite the off set variance.

Thus equation (1) is obtained to show the echoloss conditions of the resistance hybrid circuit. Here the right and left impedance centering border X-X of the one-dot chain line must be equal to each other to secure the matching between the resistance hybrid circuit and the 2-wire side. And the approximate value is secured in terms of the practical use between the impedance of the 2-wire line side and that of the 2-wire/4-wire converting circuit when viewed from the 2-wire line. Thus the impedance matching can be secured between the 2- wire line side and the hydrid side.
