Title: Automatic vertical angle compensator
Inventor: OTOMO FUMIO
IPC: G01C5/02
Filed: 1992-11-12
Abstract: PURPOSE:To allow detection of the inclination of reference plane only by a unilateral optical system by providing an anamorphic prism system and a beam expander for offsetting angular variation of reflection optical axis corresponding to the variation of incident angle of optical axis. CONSTITUTION:Liquid encapsulated in a container 4 forms a free liquid plane 1. Luminous flux is projected from a light source 6 through a collimate lens 5 onto the liquid plane 1 at a predetermined angle causing total reflection with the optical axis of the flux being set in yz coordinate plane. When the container 4 inclines to cause relative variation of the incident angle to the liquid plane 1, variation of reflection angle is detected at such sensitivity as variable depending on the inclining direction of the liquid plane 1. Difference of sensitivity is corrected optically by an anamorphic prism system 9 and relative inclination of the liquid plane 1 is optically offset by a beam expander 12 for the luminous flux reflected on a reflector 14 in the vertical direction thus keeping verticality constantly for the luminous flux reflected in vertical direction.

Abstract: PROBLEM TO BE SOLVED: To suppress the flow irregularity of a resin before flowing into a cavity and to extremely simply optimize gate balance by providing protruding members capable of being increased, decreased and altered in the protruding length into respective runners in a mold clamping state to adjust flow resistance. SOLUTION: The resin flowing through a main runner 31a and a gate 32 is increased in flow resistance and the same state as an increase in the flow length of the resin is brought about. By adjusting the length of ejector pins 26, 28 herein, the flow length and flow pressure of the resin can be adjusted so as to become substantially equal to those of the resin flowing through other main runner 31a and other gate 32. Since the respective ejector pins 26, 28 are arranged at an equal distance from the center of a cavity A, the regulation quantities of flow resistance obtained by altering the protruding lengths of the ejector pins 26, 28 coincide. Therefore, flow resistance is easily regulated.

Title: Objective lens for endoscope
Inventor: IGARASHI TSUTOMU
IPC: G02B23/24
Filed: 1988-12-28
Abstract: PURPOSE:To reduce the inclination of a main light beam even when a visual field angle is made large by composing the objective lens for the endoscope of a 1st group and a 2nd group, providing spherical surfaces which have positive power as the surface of the 1st group which is closes to the image side and the surface of the 2nd group which is closest to the object side, and satisfying specific conditions. CONSTITUTION:The objective lens consists of a 1st group I and a 2nd group II in order from the object side and both the image-side surface of the 1st group and the object-side surface of the 2nd group having positive power and meet requirements shown by inequalities 1 and 2. In the inequalities, L is the air converted length from the front focus position of the whole system to a stop, (f) the focal length of the whole system f1 the focal length of the 1st group, and f2 the focal length of the 2nd group. In this case, the inequality I is the requirement for reducing the tilt angle of a main projection light beam at the maximum image height in consideration of the spherical aberration of a pupil and the inequality II is the condition for the reduction of the inclination of a main light beam at intermediate image height when the inclination of the main light beam at the maximum image height is nearly eliminated and the optimization of the balance between the aberration of the pupil and the aberration of an image. Consequently, the inclination of the main light beam is reduced sufficiently over the entire plane of the image even when the visual field angle is made large.
