Patent CA-2091302-A1 (CA)
Title: Semiconductor laser and process for fabricating the same
Inventor: YOSHIDA ICHIRO
IPC: H01S5/06
Filed: 1993-03-09
Abstract: ABSTRACT OF THE DISCLOSURE   This semiconductor laser includes resistors as heating means through insulation films for generating pre-heat of substantially the same calorie as oscillation heat generated when the laser resonators are driven.  When the light emitting regions as the light source are driven, first the heating means is actuated to give pre-heat to the laser resonators. After the laser resonators are driven,  the heating means is stopped to decrease a calories of the pre-heat.  It is preferable that the pre-heat has substantially the same calories as the above-described generated heat, but may be below the generated heat.  Specifically, when all of the two laser resonators are driven, the heating means may generate a calories for one laser beam so as to suppress the heat crosstalks due to the mutual influence of the heat generation of the laser beams.  In this case, the heating means stops heating only while both laser resonators are being driven, and continues heating in other cases.  Thus, whether or not one and/or the other of the light emitting regions is driven, the laser chip has a substantially constant temperature, and temperature changes before and after an actuation is suppressed. As a result, laser beams of uniform output levels can be supplied to the printing unit of a laser printer.

Title: Missile guidance system and missile
Inventor: ZACHARIAS ATHANASSIOS
IPC: F41G7/22
Filed: 1993-03-25
Abstract: A staged missile having a booster stage, sustainer stage, fuel source, steering electronics, warhead and homing head is used for striking a target, such as a helicopter, from above. The missile is braked after a ballistic flight before a target zone and is redirected to a direction substantially perpendicular to the ground surface over the target zone such that the homing head of the missile hanging from the brake parachute is directed downwardly. Once the homing head has locked in on the target, the brake parachute is jettisoned and the missile is directed to the target by the sustainer thruster. Near the time of deployment of the brake parachute, a transverse thruster is activated at the centre of gravity of the missile such that a force is produced which is added vectorially to the earth's gravitational force to firstly accelerate the tilting of the missile to the vertical direction, and during the homing phase associated with the redirection, to secondly counteract roll, pitch and yaw movements of the missile and for stabilization.

Title: Method and apparatus for producing tubular printed product packs with a tear-out aid
Inventor: STAUBER HANS-ULRICH
IPC: B65B61/18
Filed: 1993-08-16
Abstract: A B S T R A C T     Tubular packs (P), which contain at least one wound, flexible, flat article, particularly a scale formation of printed products, are produced by winding the scale formation and by winding during the same winding process a protective/holding element (10), which is proportioned in such a way that its surface directed inwards on the pack and its outer edge (12) in an overlap area (11) rests on its outwardly directed surface, the two surface areas at least zonely sticking to one another.  If, according to this method, packs with varying diameters are produced, it is advantageous to produce the protective/holding elements by cutting from a corresponding material.  To facilitate the opening of such packs, during the winding process advantageously between the two overlapping surfaces of the protective/holding element a marking element (20) or an edge-marking coating is applied and this can simultaneously serve as e marking of the outer edge (12) of the protective/holding element and also for the gripping of said edge.
