Filed: 1992-07-16
Abstract: PURPOSE:To prevent generation of mounting defects such as Manhattan phenomenon of a chip when a substrate pattern for surface mounting suitable for a high frequency circuit of telecommunication equipment, for example, and to prevent effect on the dislocation of a land position by the dislocation of a resist film, at the time of manufacturing a substrate. CONSTITUTION:A board 1 is provided with a land section 8 having the radius R formed by etching a conductive material 2 adhered to the wide range on a substrate 1, and it is provided with a plurality of depressed sections composed of the conductive material 2 in the range from the radius R to the radius (R+100mum). The top of the land section 8 and the depressed sections 9 are covered with a resist film 10, and heat conductivity is reduced by providing the depressed sections 9 composed of the conductive material 2 around the land section 8, thereby the same degree of heat conductivity as its counterpart land pattern can be obtained, and Manhattan phenomenon of the chip can be eliminated.

Title: Light guide and its production
Inventor: YAMAZAKI KOJI
IPC: G02B6/13
Filed: 1988-07-28
Abstract: PURPOSE:To allow the effective confinement of light by laminating a clad layer consisting of a II-VI compd. semiconductor and a waveguide layer consisting of a II-VI compd. semiconductor having the refractive index larger than the refractive index of the clad layer to a part on a substrate. CONSTITUTION:This light guide has the GaAs substrate 1, the clad layer 2 consisting of ZnS and the waveguide layer 3 consisting of ZnSe. While the refractive index of the ZnSe of the waveguide layer 3 is 2.34 in the direction perpendicular to the boundary, the refractive index of the ZnS of the lower clad layer 2 is 2.31 and the upper part is the atm. of 1.0 refractive index and, therefore, the difference in the refractive index is sufficiently large. The struc ture in which the waveguide layer having 2.34 refractive index is sandwiched by the atm. of 1.0 refractive index is adopted even in the direction parallel with the boundary and, therefore, the difference in the refractive index is suffi ciently large. The confinement of light into the waveguide layer is effectively executed in this way and the absorption in the GaAs substrate is small.

Abstract: PURPOSE:To contrive to decrease the burden of an external control device and to improve the throughput of the whole of a system by executing directly the detecting without detecting a seek error and executing automatically the correcting when the position of a head is dislocated due to the oscillation and a shock. CONSTITUTION:When a head is at the position of '0' and the position of the head is moved due to the shock, etc., a track zero signal I TR0, which is the output of a sensor 2, comes to be a low level and as the result, a correcting signal CS comes to be a high level. When the correcting signal CS comes to be a high level, a control circuit 5 generates a single pulse (c) in a driving pulse D DVP as shown in the figure, for example, by frequency-dividing the clock pulse of a built-in oscillator. The single pulse (c) drives a pulse motor for driving the head through a pulse motor driving circuit and the head is driven in the direction in which the number of the track is decreased. Thus, at the control device, each time a seeking error is detected, the operation to return the head to an original point is not necessary and the throughput of the whole of the system is improved.
