Semiconductor laser apparatus wherein a semiconductor laser device and a temperature sensor for sensing the temperature of the laser device are mounted on a heat sink or base and airtightly encapsulated. In one embodiment the heat sink or base is mounted on temperature control apparatus which in turn is electrically controlled in response to the output from the temperature sensor. In another embodiment, a laser beam intensity sensor whose output varies over a wide range depending upon an environmental temperature is also temperature controlled so that the semiconductor laser apparatus may be controlled with a higher degree of accuracy.

In a semiconductor laser optical system which uses a light source a semiconductor laser having different diverging points and divergence angles in orthogonal directions and in which the light beam from the light source is imaged on a scanned surface, only a spherical surface optical system is provided between the semiconductor laser and the scanned surface. The spherical surface optical system includes two partial optical systems, i.e. a first image forming optical system and a second image forming optical system as viewed from the light source side. By selecting the optical constant of one of the two image forming optical systems to a predetermined value, the peak power of the image forming spot on the scanned surface is maximized.

This specification discloses a recording apparatus which is capable of representing half-tones of an image. The apparatus is provided with a device for varying the spot size of a recording beam on a recording medium in accordance with the density information of the image to be recorded in order that the half-tones of the image may be represented by the use of a screen dot system. This device causes aberration to the optical system used therein, to thereby vary the size of the beam spot impinging on the recording medium and if required adjust the quantity of light of the beam to create spots of different diameters. Thus, without relatively increasing the power of the beam, it is possible to provide beam spots of various diameters to thereby enable representation of a half-toned image.

The present invention is directed toward anionic polymerization employing lithio amines mixed with an organic alkali metal compound and optionally, a chelating reagent. The lithio amines have the general formula (A)Li(SOL)y, where SOL is a solubilizing component, A is an alkyl, dialkyl, cycloalkyl or dicycloalkyl amine radical or a cyclic amine, and y is 0 or is from about 0.5 to about 3. The invention is also directed toward polymers and other products made using the initiator, and methods therefor. Further, the invention contemplates a polymer, a polymer composition and products therefrom, which include a functional group from the reaction product of an amine and an organolithium compound. The resulting polymers may be terminated with a terminating, coupling or linking agent, which may provide the polymer with a multifunctionality.
