Title: Control system of laser diode
Inventor: IMAMURA TOMOATSU
IPC: H01S5/042
Filed: 1987-12-30
Abstract: PURPOSE:To realize an ON/OFF control system by a simple circuit formation at a low cost, by connecting resistance to a laser diode in parallel and turning switching elements ON or OFF, thereby controlling a differential current through bypass operations after charging a drive current of the laser diode into a constant current which is required to obtain a prescribed quantity of light. CONSTITUTION:Switches SW 1 and 2 are in a state of ON immediately before a video signal VIDEO (binary signal) is given in a driver 17 and a feedback loop is formed. Input voltage Vi of a driver 16 is controlled by comparator 18 and the driver 16 allows a drive current Is (oscillation starting current) + Id to flow into a laser diode LD according to input voltage Vi of a differential current and then, its diode emits light at a constant intensity of light. Just before a video signal VIDEO is inputted to the driver 17, the switches SW 1 and 2 turned to OFF and allow the input side of a sampling hold circuit 19 to be opened and the output side to be connected to the input line of the driver 16.

Title: Planographic ink composition
Inventor: KAMIYA MAKOTO
IPC: C09D11/108
Filed: 1989-12-26
Abstract: PURPOSE:To obtain a planographic ink composition which can maintain its printing suitability for a prolong period of time by incorporating into a planographic ink composition fine particles of a resin with a high water absorbency which has absorbed specific water, thus preventing the ink composition from being contaminated when dampening water is in a short supply. CONSTITUTION:Water that has been adjusted to have a pH value of 2.0 to 7.0 with an acid or its salt is absorbed in highly water-absorbent resin particles having particles sizes of 5mum or less. The amount of the water is 50 times or less the amount of the resin particles. As a result, resin particles of 150mum or less that contain the above-mentioned water are obtained. These particles are then compounded with a main component of oil-base ink such as an alkyd resin, a (rosin-modified) phenol resin, an epoxy resin or a petroleum resin, a colorant, and optionally an ink modifier, whereby an ink composition is obtained. The weight of the resin particles accounts for 1 to 30% of the weight of the composition.
