Title: Optical transmitter and laser diode module
Inventor: MISAIZU SETSUO
IPC: H04B10/40
Filed: 1994-12-20
Abstract: PURPOSE: To stably provide fixed optical output regardless of temperature change without using a Peltier element by coupling a laser diode module and the driving circuit in terms of AC. CONSTITUTION: This laser diode module 34 and the driving circuit 33 are coupled by a capacitance 37 and separated in terms of DC. Thus, problems in the case of simply removing the Peltire element, that are the saturation of a driving circuit output stage owing to the increase of a driving current by temperature rise and the influence of the laser diode module in terms of DC, can be evaded. A power control circuit APC 36 controls a pulse current to be supplied to a laser diode corresponding to the optical output and maintains the optical output fixed regardless of the temperature change. Also, by supplying an offset current equivalent to the I/N of the amplitude of a driving pulse current, the APC 36 makes a bias current equivalent to a threshold current flow at all times. In such a manner, since the Peltier element is not used, power is saved and miniaturization is achieved.

IPC: B01D9/02
Filed: 1993-11-24
Abstract: PURPOSE:To perform crystallization excelling in an aptitude for production even with a general-purpose device by first adjusting the supersaturation of organic chemical solution to crystallize flat crystals and then lowering the temp. to continue the crystallization of the flat crystals while the composition of solvent is changed. CONSTITUTION:A crystallizer 20 is provided with a kettle 22, an agitating blade 24 equipped with a bar blade, and a baffle 26 almost in the shape of F. When an organic chemical, such as a cyanic coupler, is dissolved in a good solvent, such as ethyl acetate and is fed into the kettle 22 and a poor solvent, such as methanol, is gradually added to it under agitation while the liquid temp. maintained, mainly flat crystals begin to crystallize by supersaturation. Next, while another poor solvent, such as water, is added to lower the saturation solubility of the flat crystals in the organic chemical by changing the solvent composition the temp. is lowered to continue the crystallization of the flat crystals. In this process, the agitating speed of the agitator 24 is adjusted to make the crystallized flat crystals in a complete floating state. After that, the mixture is cooled and separated into the crystals and mother liquor.
