Title: Metal mold structure for casting
Inventor: OTA ATSUSHI
IPC: B22D17/22
Filed: 1993-08-27
Abstract: PURPOSE:To decrease working allowances for cutting after casting by forming the inside diameter of a recessed part formed by casting to the same diameter as far as possible over the entire length. CONSTITUTION:An auxiliary metal mold 3 in the metal mold structure having the auxiliary metal mold for forming the recessed part in the casting by projecting into a cavity space 10 is formed of a material having the coefft. of thermal expansion equal to or higher than the coefft. of thermal expansion of the molten metal to be poured into the cavity space. The auxiliary metal mold 3 expands to press the molten metal at the time of casting and shrinks larger than the casting at the time of cooling, thereby producing a clearance with the recessed part. There is, therefore, no need for forming a draft taper on the auxiliary metal mold 3 and the need for cutting the recessed part after casting is obviated.

Inventor: YAMAUCHI HIDEKI
IPC: H01S5/042
Filed: 1989-08-18
Abstract: PURPOSE:To effectively hold down relaxation oscillation with a simple structure by a method wherein the average optical output of a main semiconductor laser is detected, and the drive current of an auxiliary semiconductor laser is so controlled as to maximize the average optical output concerned, and the semiconductor lasers are made coincident with each other in axial mode. CONSTITUTION:Light is injected into a main semiconductor laser LD2 from an auxiliary semiconductor laser LD1, and the laser LD2 emits laser rays. The emitted laser rays are injected into a PIN photodiode PD which monitors the optical output of the laser LD2, and the average voltage VP of the optical output concerned is measured by a voltmeter. The voltage of a variable voltage source 2 is changed observing the measured voltage. When the average voltage VP of the optical output is measured, the voltage VP is separated into a high voltage region A and a low voltage region L, and the relaxation oscillation of the optical output waveform of the main semiconductor laser LD2 is restrained in the region A. The axial modes of the main laser LD2 and the auxiliary laser LD1 are coincident in axis. That is, the current of the auxiliary laser LD1 is adjusted so as to maximize the optical output monitoring voltage VP.
