Patent JP-H02106712-A (JP)
Title: Endoscope device
Inventor: MIYAZAKI AKIHIKO
IPC: G02B23/26
Filed: 1988-10-14
Abstract: PURPOSE:To secure a visual field which can keep safety with the aid of using a lamp which is inexpensive and whose power consumption is a little as an auxiliary light source by switching the amplification degree of an image signal to a high value at the same time that the auxiliary light source is turned on when a main light source is turned off. CONSTITUTION:An amplification degree change-over switch 50 is provided in an amplification circuit 49 and set so that it is turned on when the main light source 43 is turned on and turned off when the main light source 43 is turned off. The amplification degree of the amplification circuit 49 is set to about 9 times when the amplification degree change-over switch 50 is turned on and about 100 times when it is turned off. When an electric discharge lamp is turned off, a non-lighting detection circuit 53 detects it and sends a signal to a control circuit 52. Then, the control circuit 52 makes an emergency lamp 4b intervene in a lighting optical path and the emergency lamp 4b is turned on by an auxiliary light source lighting circuit 54. Simultaneously, the amplification degree change-over switch 50 is turned off by the signal from the control circuit 52 and the amplification degree is switched to 100 times. Thus, the visual field of an endoscope can be secured even by the emergency lamp 4b whose output is low in comparison with that of the electric discharge lamp 43.

Abstract: PURPOSE:To make it possible to prevent the wave of a convection layer from generating and also a stirring phenomenon at the time of water supply from occurring and restore the light permeability of the diaphragm by disposing in contact with each other a plurality of pipes provided with water supply and drain ports opening toward the longitudinal direction in a upper convection layer on the surface of a diaphragm main body. CONSTITUTION:A number of pipes 4 are arranged at a suitable interval L mutually in parallel so that they rectangularly intercross in a direction where natural wind 7 most dominate. When natural wind 7 occurs in the direction of an arrow, the surface of the upper convection layer 1 is agitated in waves but pipes 4 provided rectangularly to the natural wind 7 suppress the waves. The promotion of heat radiation due to stirring and increase in the heat radiation area which occur at the time of generating waves can be prevented. The water supply and drain port of each pipe 4 is provided adjacent to the surface of the diaphragm main body 3 in the form of a slit toward the longitudinal direction, and supply water is widened so that it slides along the surface of the diaphragm 3, and hence stirring due to supply water can be reduced. By draining the upper convection layer 1 from the supply and drain port 5, dusts and weeds on the surface of the diaphragm main body 3 can be removed and the light permeability can be restored.
