Title: Timing stabilizer
Inventor: SUGIYAMA SUNAO
IPC: H01S3/13
Filed: 1991-03-27
Abstract: PURPOSE:To diminish the jitter of output pulse beams of a mode lock laser by a method wherein the higher harmonics of repeated frequency of output pulse beams of a mode lock laser as well as the phase difference between the higher harmonics and the reference signals are detected so as to control the phase of the driving signals according to the detected phase difference. CONSTITUTION:A part of output pulse (repeating frequency f1a) 100 of a mode lock laser 9 is entered into a photodetector 1. The photodetection signal 101 having a repeating frequency Nf1a is outputted from a band filter 2. A phase detector 3 detects the phase difference between the photodetector signal 101 and a reference signal 102 having the repeating frequency Nf1a oscillated from an oscillator 7 so as to output an error signal 103. A control circuit 4 outputs a phase control signal 104 to a phase shifter 5 according to the error signal 103. The phase shifter 5 whereto the reference signal 102 is inputted from the oscillator 7 is to be position-shifted by the phase control signal 104 so that the position-shifted reference signal 102 may be outputted to a divider 6 as a driving signal A105.

Title: Method for mounting slit vent for die casting
Inventor: FURUYA TAKEO
IPC: B22C9/00
Filed: 1987-04-13
Abstract: PURPOSE:To prevent generation of casting defects by packing a resin or adhesive agent which is expended at a prescribed temp. in the slits of a vent body and heating the slits to the prescribed temp. thereof or above, thereby decomposing and expending the resin or adhesive agent. CONSTITUTION:The slits 14 consisting of plural grooves 12 are formed to the slit vent 10 from the plane 10a to base 10b thereof. The plural grooves 16 are further formed by rolling to the circular cylindrical outside peripheral face 10d. After the adhesive agent 18 is packed into the slits 14, the slit vent 10 is mounted to the venting part of a die and the plane 10a is machined so as to be made flush with the cavity face. The adhesive agent 18 is decomposed and expended and the grooves 12 are opened when the vent 10 is heated up to the prescribed temp. by heating the die inside by a burner etc. Generation of deformation in the grooves 12 is obviated by the intervention of the adhesive agent 18 in spite of the compressive load exerted at the time of mounting the vent 10. Venting is, therefore, improved and the generation of casting defects is prevented.
