摘要:
The present invention relates to a stereomicroscope comprising an object observation unit and an electronic image unit. The object observation unit includes an objective lens barrel section and a binocular lens barrel section, with the binocular lens barrel section including an interpupillary adjusting mechanism in a light path following a first image plane. The electronic image unit includes an electronic image display device and a projection optical system The object observation unit has an object observation image that remains fixed in position at the first image plane during interpupillary adjustment of the binocular lens barrel section. The projected image from the electronic image display device is made to be substantially in focus at the first image plane. Images at the first image plane may be relayed to a second image plane. An object observation image formed by the object observation unit and an electronic image formed by the electronic image unit may be observed simultaneously in the same field of view by an observer looking into an eyepiece of a binocular lens barrel section. In one embodiment of the invention, the position within the first image plane of the projected image from the electronic image display device is adjustable within a range such that the projected image may lie within or outside of the field of view of a viewer looking into an eyepiece of a binocular lens barrel section.

The present invention is a heat insulating material being a single unit having superior insulating performance as well as sufficient mechanical strength itself to constitute furnace walls, an electric heating unit having the heat insulating material and a method of manufacture of the heat insulating material and the electrical heating unit. The heat insulating material of the present invention includes an outer layer having mainly refractory inorganic fibers and a core layer supported within the outer layer. The outer layer has greater mechanical strength than the core layer. The core layer has a composition having a better insulating performance than the outer layer and extends in a plane substantially perpendicular to the thickness of the heat insulating material. The electrical heating unit of the present invention has a heating element embedded in the heat insulating material.

A grip comprises a grip body forming a gripping control portion of a manually operable device to be held with the operator's palm and fingers. The grip body includes a ball-receiving surface coming into contact with the ball of the thumb, a palm-receiving surface coming into contact with a middle portion of the palm and the ball of the little finger, a finger-receiving surface coming into contact with the fingers, an open surface positioned between the tips of the fingers and the ball of the thumb for receiving the thumb when the grip body is held, and a switch mounted on a top portion of the grip body to be operable with the thumb. The grip body further comprises a thumb-guiding portion in the form of a shallow groove formed at an upper part of the ball-receiving surface of the grip body, the inside of the first joint of the thumb being placed along the thumb-guiding portion when the switch is operated, and a rising portion formed on at least either one of portions between the thumb-guiding surface and the open surface and between the thumb-guiding surface and the palm-receiving surface for applying resistance when the operator's hand advances into the switch.

The invention aims at providing a method for manufacturing a glass substrate for a magnetic disc capable of eliminating undulations of an outer peripheral end face of a glass substrate in a short processing time, and obtaining high roundness. In a method for manufacturing a disc-like glass substrate for a magnetic disc, the method includes a forming step of pressing a rotating grindstone against an outer peripheral end face while the glass substrate is rotated, thereby forming an outer peripheral end. In the forming step, processing is performed using a first condition (S106) on which first undulations are formed and a second condition (S108) on which second undulations having a different wavelength from the first undulations are formed.

A medical instrument holding device includes a grasping portion onto which a medical instrument is mounted, an acceptant arm supported by a link mechanism, and a ball joint element adapted to be fixed to and released from the acceptant arm. The grasping portion is connected to the acceptant arm by the ball joint element arranged above or below the longitudinal axis of the acceptant arm. A total weight of the grasping portion is always balanced so as to apply to the acceptant arm (ball joint element) so that an operator can move the grasping portion under the condition that no total weight is applied to the operator.

A magnetic polishing method capable of easily and satisfactorily polishing the inner peripheral end face of a circular hole (1) at the center part of a disk substrate (2) even if the diameter of the circular hole is reduced. By this method, a large quantity of disk substrates with stable quality can be supplied, thermal asperity trouble and head crush can be prevented from occurring on a magnetic disk, and the density of the information recording surface of the magnetic disk can be increased. In the method for polishing the inner peripheral end face of the circular hole (1) at the center part of the disk substrate (2), a magnetic field is formed on the inner peripheral side of the circular hole (1), abrasive materials (4) including magnetic particles and abrasive grains are held by the magnetic field in the circular hole, and the magnetic field is moved to the inner peripheral end face of the circular hole (1) to move the abrasive materials (4) to the inner peripheral end face of the circular hole (1) for polishing the inner peripheral end face of the circular hole (1).
