Title: Portable circular saw
Inventor: ETO NAOYA
IPC: B27G19/04
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To facilitate the pivoting operation of a safety cover and realize the favorable operability of a saw by a method wherein an operating tool is operated towards the gripping direction of a handle by binding one end of a wire to some part of the safety cover and connecting the other end of the wire to the operating tool near the handle. SOLUTION: One end of a wire 20 is mounted to the mounting hole 15 of a safety cover 11, to which one end of a spring 14 is mounted. The other end of the wire 20 is mounted to an operating tool locating near a handle 2 through the outer periphery of holder 10, which is the rotary shaft of the safety cover 11. By pulling the wire 20 through the operating tool 21, the safety cover 11 is pivoted. Since an operation can be executed only through the pulling operation performed by one hand grasping the handle 2, even during a cutting work, which is performed by employing a ruler or the like, it can easily be executed. Since the gripping direction of the handle 2 and the operating direction of the operating tool 21 are same, the holding of a main body can be prevented from becoming unstable through the operation of the operating tool 21.  Thus, the easy pivoting operation of the safety cover 11 can be realized and the favorable operability of a saw can be realized.

Title: Semiconductor laser module
Inventor: SUZUKI MASAHIRO
IPC: H01S5/068
Filed: 1988-02-26
Abstract: PURPOSE:To obtain light output having a desirable waveform all over the range of working temperatures, by monitoring a temperature of a semiconductor laser element so that a bias current control means controls bias current based on the monitored result. CONSTITUTION:A temperature sensitive element 3 contained in a semiconductor laser module monitors a temperature of a semiconductor laser element 1. Output of the temperature sensitive element 3 is inputted in a temperature-voltage converting circuit 4, which controls a reference voltage of a bias current control circuit 5 in correspondence with dependency of differential quantum efficiency of the semiconductor laser element 1 to temperatures.
