Abstract: PURPOSE:To obtain a semiconductor laser excitation solid-state laser device which is miniature and high in output power by a method wherein a pair of array-type semiconductor lasers is provided to each of reflecting points on the excitation surface of a solid-state laser medium at a certain angle which is determined taking the refractive index of the solid-state laser medium into consideration. CONSTITUTION:Two array type semiconductor lasers 2a and 2b are installed for each point on an excitation surface 1c of an Nd:YAG rod 1 and set taking an incident angle thetaLD at which laser rays are incident on the rod 1 into consideration. Laser rays emitted from the laser 2a are incident on the rod 1 as condensed by a fiber lens 3. At this point, provided that an incident angle, an outgoing angle, and the refractive indexes of air and the rod 1 are represented by thetaLD, thetaYAG, and etaAIR and etaYAG respectively, a formula I is satisfied. At this point, provided that etaAIR and etaYAG are set to 1 and 1.82 respectively, and thetaLD and thetaYAG are optimized taking conditions under which layer rays emitted from the solid laser are reflected at the excitation surface 1c into consideration, whereby an output nearly half as much as the total input can be obtained.

IPC: H01L27/148
Filed: 1994-04-12
Abstract: PURPOSE: To decrease the parasitic capacitance of a drive MOS transistor, and to improve the detection sensitivity by forming a depletion channel between the gate electrode and drain region of a drive MOS transistor, and maintaining them at constant intervals. CONSTITUTION: This device is provided with a substrate 11, a drain region 21 formed in the neighborhood of the surface of the substrate 11, and a gate electrode 19 formed on the substrate 11 so as not to be superimposed on the drain region 21. Moreover, this device includes a drive transistor, equipped with a depletion channel region 27 formed in the neighborhood of the surface of the substrate 11, so as to be connected with the drain region 21 between the gate electrode 19 and the drain region 21. Then, they are maintained at constant intervals. Thus, for example, a parasitic capacitance between the gate electrode and the drain region of a drive MOS transistor occupying about 1/3 of the input electrostatic capacitance of a typical source follower can be sharply decreased, and charge detecting sensitivity can be enhanced sharply.

Abstract: PURPOSE: To reduce the change rate of the operating power of an operating member and make possible lighting of a fluorescent lamp and setting of the pressing force of a press roller by forming the shape of a cam which is turned by the operating member to an involute curve in a diazo type copying machine.  
     CONSTITUTION: When an operating member 16 is manually turned in the arrow direction from the first position A where the copying machine has stopped, the cam member 15 integral with said member 16 rotates around an axis 14 against the elastic force of a spring 21. Then, the cam part 15a begins to contact a cam follower 24 and since the cam part 15a is made in involute curve form, the cam follower 24 is gradually pushed upward and this gradually increases the pressing force of a press roller 9 onto a press roller 8, thus gradually increasing the pressing force of the press roller onto a developing roller 7. Next, the cam follower 24 drops into the serrated part 15c, causing a microswitch 27 to actuate to start the main drive motor of the copying machine. When the operating member 16 turns further, it contacts the stopper part 15e and stops, causing a microswitch 26 to actuate to light a fluorescent lamp.
