Title: Pulverizing pin
Inventor: TANAKA HIROAKI
IPC: B02C13/06
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To enable improving pulverizing efficiency by fixing a taper part of a metal member in a taper through-hole of a ceramic member and making, in the taper through-hole of the ceramic member, the diameter of its bottom part specified times that of its head part. SOLUTION: In a through-hole of a ceramic member, the diameter of its bottom part is made 1.0-7.0 times that of its head part. The reason why the through-hole is made to have the shape of such a taper is that even in a cantilever system, sufficient strength for supporting a ceramic material 43 and withstanding pulverizing force is secured and also a certain measure of pulverizing efficiency can be obtained. More preferable value of the strength is 1.4-3.5 times the pulverizing force. The outer peripheral shape of the ceramic member 43 is, for example, cylindrical, and in that case, the diameter of a bottom part of a metal member 44 is preferably made 1/4-1/2 or 1/3-3/5 times the outer diameter of the ceramic member 43. In this way, sufficient strength of the ceramic member 43 and the metal member 44 is secured to better the strength balance of the two.

Title: Semiconductor laser driver
Inventor: KADOWAKI HIDEJIRO
IPC: H01S5/042
Filed: 1992-12-25
Abstract: PURPOSE:To prevent a semiconductor laser from being damaged and to prevent the abnormal emission of laser light due to the runaway of an APC circuit by a method wherein driving current of the semiconductor laser is monitored apart from the APC circuit of the semiconductor laser to detect the runaway of the APC circuit and the supply of power to the APC circuit is stopped when the runaway of the APC circuit is detected. CONSTITUTION:Current is supplied to an APC circuit from a switching circuit 5 when a photo coupler 51 is on. An APC trouble detecting circuit 1 detects current IL which flows in a semiconductor laser chip 21 as voltage across a resistor 44 and it turns off the photo coupler 51 of the switching circuit 5 when the detected value of the voltage is equal to or above a specified value. Power is supplied to the APC trouble detecting circuit 1 from a power supply + Vcc, a different power supply from that of the APC circuit A. And, the voltage across the resistor 44 is converted into a voltage level of the APC trouble detecting circuit 1 by means of an amplifier 11. An A/D converter built-in CPU 12 outputs a signal which turns off the photo coupler 51 when the voltage is equal to or above the specified level. The supply of power to the semiconductor laser is thus controlled.
