Title: Semiconductor laser element
Inventor: MAEI SHIGEKI
IPC: H01S5/00
Filed: 1986-01-31
Abstract: PURPOSE:To realize excellent I-L characteristics by a method wherein a current is not injected into the region near the end surface of a resonator waveguide to avoid the deterioration of the end surface caused by Joule heat and that region is excited by an emitted light from an LED operating part whose current is controlled by independent electrodes. CONSTITUTION:When a current is applied between a P-type electrode an an N-type electrode of an LED operating part provided at the end position of a resonator, an active layer 16 directly above a V-groove 14 operates as an LED and emits a light. The emitted light propagates in the active layer 16 and is injected into the end surface region of a laser oscillation waveguide. In other words, the region near a resonance end surface with is to be saturable absorption element and into which a current is not injected is excited by the injection of the emitted light from the LED operating part. With this constitution, the absorption of the laser beam at the laser oscillation operating part is reduced and improvement of the linearity of I-L characteristics can be achieved. Moreover, as the LED operating part has electrodes independent from the laser operating part, the deterioration of the I-L characteristics caused by the insufficiency of emitted luminance of the LED operating part can be avoided and the yield of the manufacture of the element can be improved and, further, as Joule heat is not created in the laser beam waveguide region near the end, the deterioration of the end surface can be suppressed.

Title: Optical branching device
Inventor: YONETANI KAZUYUKI
IPC: G02B26/08
Filed: 1989-01-30
Abstract: PURPOSE:To shorten the switching time of channels and to branch pulses, one by one, on a time-division basis by providing mirrors which are arranged at equal intervals along an optical path of incidence and a mirror driving mechanism which rotates the mirrors while maintaining a constant tilt angle to incident light. CONSTITUTION:A time-division branching unit 11 is equipped with the four mirror members 15a - 15d which are arranged at equal intervals along the optical path 14 of the incident light 13 and the respective mirror members 15a - 15d are rotated at constant speed by the mirror driving mechanism 16 while holding the tilt angle at, for example, 45 deg. to the incident light 13. Therefore, even when the respective mirrors rotate at all times, the incidence angle of the incident light on the respective mirrors does not vary and the light never deviates from the optical axis. Consequently, the switching time of the channels can be shortened and a pulse laser which has a fast pulse rate can divide pulses, one by one, on a time-division basis.

Title: Ion implantation device
Inventor: TAKAHASHI TAKETO
IPC: H01J37/317
Filed: 1987-01-30
Abstract: PURPOSE:To prevent a semiconductor substrate from being adversely affected when high-density ions are implanted by applying the uniform potential distribution with the preset polarity to a disk fitted with the semiconductor substrate. CONSTITUTION:When a constant-voltage source 8 applying the optional positive bias voltage to a disk 4 is provided, the optional positive bias voltage is applied to an element produced in a semiconductor substrate 3, e.g., gate section A of MOS transistor, by the constant-voltage source 8. As a result, in the case of implantation of high-density ions into the semiconductor substrate 3, electric charges are accumulated at the gate section A when ions are implanted, and the voltage V1 causing the electrostatic breakdown at this portion tends to occur. However, the voltage V2 to compensate for the voltage V1 is applied to the gate section A by the constant-voltage source 8, thus the voltage V1 is offset by the voltage V2. Accordingly, the breakage of the element produced in the semiconductor substrate 3 can be prevented or reduced.

Title: Phase locked signal extraction circuit for television signal
Inventor: OTAKA TOSHINORI
IPC: H04N5/08
Filed: 1989-01-31
Abstract: PURPOSE:To execute the stable extraction of a phase locked signal even when the phase locked signal of positive polarity is adopted to a recording/reproducing system by setting an initial phase and an initial frequency in a horizontal phase locked loop circuit based on the internal phase and frequency after an auxiliary phase locked loop circuit achieves a normal state and executing the initial lead-in operation of the horizontal phase synchronization circuit. CONSTITUTION:In the normal state of an auxiliary phase locked loop circuit 5, the phase and frequency of an auxiliary phase locked signal in an input television signal S1 are almost equal with the internal phase and internal frequency of the auxiliary phase locked loop circuit 5. Accordingly, when the initial pull-in of a horizontal phase locked loop circuit 4 is next executed, the initial phase and initial frequency can be initially set based on the internal phase and internal frequency of the auxiliary phase locked loop circuit 5 and for the horizontal phase locked loop circuit 4, not only the initial phase but also the initial frequency are set to a value extremely close to those of the horizontal phase locked loop signal in the input television signal S1. Thus, even in the case of the recording/reproducing system, for which the difference of the initial frequency is large between a horizontal phase locked reference signal and the horizontal phase locked signal in the input television signal, the stable extraction of the phase locked signal can be executed.
