IPC: G02B23/26
Filed: 1995-06-26
Abstract: PURPOSE: To change a photographing range by pairing two fixed focus lenses having the same focal distance, mounting two or more pairs of fixed focus lenses having different focal distances symmetrically with respect to a rotary shaft, rotating them and stopping any pair of fixed focus lenses out of two or more pairs of fixed focus lenses at the position of an image pickup element. CONSTITUTION: The pairs of lenses 3a and 3b, and 4a and 4b are attached to the same position (plane) in the optical axis direction of a lens attaching part 2. An optical-axis-direction lens extending mechanism consisting of a groove 11 and a projection 12 is provided at the inner peripheral part of the lens barrel of a stereoscopic endoscope 1 and the outer peripheral part of the attaching part 2. By rotating the attaching part 2, a pair of lenses is selected as an image pickup lens out of plural pairs of lenses, and distances between the principal point of the lens and the image pickup elements 6a and 6b in the optical axis direction are changed. For example, the inclination angle of the groove 11 at which the distances from the principal points of the lenses 3a and 3b to the image pickup surfaces of the elements 6a and 6b become d1 is set.  Thus, focusing point is obtained by any selection.

Title: Overrevolution preventing apparatus for engine
Inventor: ARAI HIDEO
IPC: F02P11/02
Filed: 1981-10-06
Abstract: PURPOSE:To obtain an overrevolution preventing apparatus with a simple constitution by connecting two thyristors in series between the power generating coil and the ignition condenser of a contactless ignitor and preventing the overrevolution through the electric discharge of the condenser which is associated with shortening of the voltage duration time. CONSTITUTION:Each cycle of the positive and the negative voltages V1 and V2 which are generated in an ignition power-generating coil 3 shortened gradually associated with increase of the speed of engine revolution, and when a prescribed revolution speed is reached, the angle of revolution in which a thyristor 20 is set OFF by the charged voltage in a condenser 24 coincides with the revolution angle in which a thyristor 21 is set ON by the voltage V2 in the negative direction. In other words, both thyristors 20 and 21 are ON-operated, so the electric charge of a condenser 5 charged with a voltage V1 is discharged in the circuit consisting of a diode 19, thyristor 20, diode 18, and a coil 3. Therefore, even if a thyristor 6 is turned ON by the voltage V2 in the revolution angle, neither electric discharge nor ignition occured in the circuit of a primary coil 13, since electric discharge of a condenser 5 is completed, and then the revolution speed of the engine sharply reduces.

Abstract: PURPOSE: To increase the working efficiency, by preventing the change of the picture concentration in the printing course, of a sheet of paper even though the development bias voltage has been reset at any time during the copying work.  
     CONSTITUTION: When the main switch is turned on, the CPU5 starts to secure an automatically setting of the development bias at the standard value V 2 . For instance, if the development bias voltage is set again during the period from initiation to completion of the developing treatment, the paper to which the development is started receives the development up to the completion by the development bias voltage which is delivered from the development bias voltage output device 2 at the  time of initiation. the development bias voltage after an alternation is decided based  on the subroutine of the CPU5 and then stored in the RAM6B. Thus the development is given to the subsequent sheets of paper with the bias voltage after the alternation. In such way, the operation can be facilitated to increase the working efficiency.
