摘要:
A connector includes an insulating housing, a metal shell that covers the insulative housing, and a switch. The switch includes a fixed contact and a movable contact. The fixed contact is formed by partially bending a rear end of a top surface of a metal shell downward. The metal shell covers an insulating housing to be mated with a mating connector. The movable contact extends while having a fixed end held by the insulating housing, and bifurcates at an approximate midpoint of the movable contact. The movable contact has, at one free end, an attachment section that abuts a mating connector approaching in a mating direction and a contacting section, at an opposite free end, that contacts the fixed contact when the attachment section is pushed by the mating connector.

A connector includes a plurality of first contacts each having a contact arm that contacts a first surface of an object of connection and a plurality of second contacts each having a contact arm that contacts a second surface of the object of connection. The plurality of first and second contacts are alternately disposed in a contact arrangement direction in a housing. Each of the first contacts has a first projection that extends from a front end of the base member adjacent to a lower press-fitting member along an axial direction of a first contact accommodating compartment. Each of the second contacts has a second projection that extends from a front end of a base member adjacent to an upper press-fitting member along an axial direction of a second contact accommodating compartment. The first and second projections contact inner wall surfaces of projection receiving openings formed in the housing.

The invention provides an apparatus which detects light quantity distribution characteristics of a measuring target image projected to a fundus of an eye to be inspected and measures eye optical characteristics from the light quantity distribution characteristics. A projecting optical system has a light source and projects a measurement target to a fundus of an eye to be inspected by bundle of rays emitted from the light source, and a light receiving optical system condenses the bundle of rays reflected from the fundus of the eye. A photoelectric detector detects light quantity distribution characteristics of an image formed by the light receiving optical system, and an arithmetic unit measures eye optical characteristics of the eye based on a signal output from the photoelectric detector. A deflecting optical member for deflecting bundle of rays incident into both optical paths of the projecting optical system and the light receiving optical system is arranged so as to be rotatable.

A card edge connector 1 capable of effectively restraining a daughter board B from inadvertent removal in the horizontal direction by increasing the holding pressure of the daughter board B. The card edge connector 1 has an insulated housing 10 mounted onto the mother board A and latch members 30A, 30B attached to the housing 10, for holding the daughter board B. The latch members 30A, 30B have a daughter board locking portion 47a for restraining the daughter board B in the horizontal direction. The locking portion engages the inner wall of the semicircular recess B1 formed at the edge portion of the daughter board B. The daughter board locking portion 47a has a pointed edge portion 47c for penetrating the inner wall of the semicircular recess B1.

A method of producing a difluorobenzyl ether derivative (6) in which a benzene derivative (1) is reacted with a base to form carbanion which is in turn reacted with a difluoromethane derivative (2) to give a benzene derivative (3) which is further reacted with a phenol derivative (5) in the presence of a base.
摘要:
A method of detecting deficiency of an aperture used in a charged-particle-beam exposure process employing at least two exposure columns is disclosed, where each of the two exposure columns passes a charged-particle beam through the aperture formed through a mask to shape a cross section of the charged-particle beam before exposing the charged-particle beam onto an object. The method includes the steps of mounting masks having the same aperture to the at least two exposure columns; scanning, in each of the at least two exposure columns, the charged-particle beam over an area containing a mark on a surface substantially at the same height as the object after passing the charged-particle beam through the same aperture; obtaining, in each of the at least two exposure columns, a signal waveform corresponding to the scan by detecting charged particles scattered by the mark; and comparing the signal waveform between the at least two exposure columns.
