Filed: 1979-03-30
Abstract: PURPOSE:To highly stabilize the light output of a light source device by eliminating the lack of stability of the distribution ratio at the light distribution section by means of a mode scrambler. CONSTITUTION:The output from a semiconductor laser diode 1 is applied to a mode scrambler 9. The mode scrambler 9 eliminates the higher modes and clad mode so that, at the output side of the scrambler 9, mode is stabilized sufficiently and fluctuation of angle of emergence is completely avoided to ensure a stable light distribution 3. The light having passed through a half mirror 4 comes into a next mode scrambler 10 where the higher modes generated in the distributor 3 are eliminated. The feedback photosignal reflected by the half mirror is subjected to a photoelectric conversion by a PIN photodiode 6 and then to a D.C. amplification 7. The amplified signal is fed back to a driver circuit 8 of the laser diode to control the D.C. bias. This arrangement ensures a highly stabilized photo output.

Title: Clutch preload mechanism
Inventor: INOKUCHI IWANE
IPC: F16D48/02
Filed: 1989-02-21
Abstract: PURPOSE:To reduce the cost of production owing to structural simplification by installing a first check valve in the point midway in an oil passage in the clutch engaging direction and also a second check valve installed in the clutch disengaging direction in parallel with the first check valve, respectively. CONSTITUTION:Reciprocative oil passages 22, 23 are composed of each of first and second check valves 25a, 25b installed in these oil passages 22, 23 lying between a pressure control valve 14 and a clutch 21. With this formation, at time of nonoperation of the clutch 21, clutch working pressure fed to the clutch 21 from the pressure control valve 14 via the first check valve 25a is cut off and simultaneously the residual clutch working pressure as run past the second check valve 25b is drained via the pressure control valve 14. At this time, the clutch working pressure is never made into zero for the second clutch 25b, and since a cracking pressure portion is left behind there, this portion is utilizable as preload. Thus, the desired preload is realizable with only accuracy control at the side of these check valves 25a, 25b simple in structure, so that the pressure control valve 14 is simplified in terms of structure and a decrease in cost can be thus promoted.
