Title: Electronic connector
Inventor: HIGAMI TOSHIYA
IPC: G01R1/073
Filed: 1987-01-30
Abstract: PURPOSE:To obtain large force at the time of operation in a stored shape and to make an operation characteristic constant, by making a shape memory spring common to at least two or more contacts. CONSTITUTION:A plurality of contacts 3 are received in the contact chamber 2 of a connector housing 1 so as to form a row in the longitudinal direction. When a current is supplied to a heater 8 and a shape memory spring 4 of which the surface is covered with an insulating layer 7 is heated to 80 deg.C or more, the shape memory spring 4 returns to the stored shape and the mutual interval between a contact base part 3B and a contact spring part 3C is opened and a partener contact 9 can be inserted and pulled without requiring insertion and pull force. When the supply of a current to the heater 8 is stopped and temp. falls, for example, to about 50 deg.C, the shape memory spring 4 becomes soft and the spring force of each of the contacts overcomes that of the spring 4 and the contact spring part 3C is pulled back to the contact base part 3B and the partener contact is grasped under predetermined spring pressure.

IPC: G06F3/06
Filed: 1991-02-12
Abstract: PURPOSE:To access to 2HD media having a different recording density by adding a flag for the motor rotational frequency control to a 2-mode FDD control flag. CONSTITUTION:When media are inserted into a 3-mode FDD 5, the access is performed to the media, and classification of the media inserted into the FDD 5 by the previous access is known, the access is performed by a main body CPU 1 at the same transfer rate and the same motor rotational frequency. Since the classification of the media is not known when new media are inserted into the FDD 5, a parameter when the access is tried at first in order to decide the classification of the media is set to an internal flag. Thus, the access for the media is performed, the access is performed by a correct parameter and then, the access of the media is normally completed by one trial. When the access is abnormally completed, the access for the media is performed by the parameter to try next.

Abstract: PURPOSE:To reduce the width of an active layer remarkably by making the width of the upper end of a clad layer on the semiconductor substrate side larger than that of the lower end of a clad layer immediately above the active layer. CONSTITUTION:An N-clad layer 2, an N-light guide layer 3, an active layer 4, a P-clad layer 5 and a P-cap layer 6 are grown on an N-substrate 1 in succession. The refractive indices of the layer 2 and the layer 5 are set to values smaller than that of the layer 4 at that time. The refractive index of the layer 3 is set to a value smaller than that of the layer 4 and larger than that of the layer 2. Each layer is etched in the direction of a trapezoid of which the upside is smaller than the downside in a sectional shape. Only the layer 2 and the layer 5 are etched selectively. The exposed section of the exposed layer 4 is removed through etching. Accordingly, since a mesa stripe is formed in the direction of the trapezoid of which the upside is smaller than the downside in the sectional shape, the width of the layer 5 is made narrower than that of the layer 2, and the width of the layer 4 can be reduced extremely.
