Title: Modulation element control circuit of automatic focus circuit
Inventor: KAWAGUCHI NAOKI
IPC: G02B7/36
Filed: 1989-11-20
Abstract: PURPOSE:To adjust the deviation of the phase caused by a secular change and a temperature change or the like and to detect a focal position accurately by keeping a relation of phase between the displacement of a modulation element and a vertical synchronizing signal the same at all times. CONSTITUTION:Since an intermediate value comparator section 18 gives a signal in response to an intermediate level difference  V=V4-V2 extracted and held by sample-and-hold circuits 15, 16 to a phase shift section 19, the phase of a sinusoidal wave is shifted in the advancing direction and the phase of a drive signal B is changed in the direction of arrow F. As a result, a displacement C of a modulation element 4 is as shown in solid lines and the phase is controlled so as to eliminate the intermediate level difference  V. Thus, the deviation in the phase caused by the secular change or temperature change is adjusted and the focal position is accurately detected.

Title: Semiconductor device and its manufacture
Inventor: MORI MITSUHIRO
IPC: H01L29/812
Filed: 1988-12-02
Abstract: PURPOSE:To contrive a reduction in a leakage current in the gate of an element and the improvement of high-frequency characteristics of the element by a method wherein the mesa sidewalls of an InGaAs layer are protected with insulating films to avoid the direct contact of a gate electrode with the layer. CONSTITUTION:Mesa sidewalls of an undoped InGaAs layer 12 are protected with first and second insulating films 15 and 17 and it becomes an essential condition that two kinds of these insulating films have a selectivity to etching. As the upper surface of the layer 12 is protected with an N-type GaAlAs layer 13 and the mesa side surfaces of the layer 12 are protected with the insulating films, the layer 12 does not come into contact directly with a gate electrode 18. Therefore, the improvement of the efficiency of an element due to a reduc tion in a leakage current in a gate can be contrived. In such way, the mesa side surfaces only are covered with the insulating films so that the electrode 15 does not come into contact directly to the active layer 12 containing In. Thereby, the high-frequency element, which is superior in either of the break down strength of the gate and high-frequency characteristics, is obtained.
