Title: Light higher harmonics generating device
Inventor: HOSHINO ISAO
IPC: H01S5/00
Filed: 1990-11-30
Abstract: PURPOSE:To obtain a small-sized light higher harmonics generating device from which a large output can be obtained, by giving higher reflectance to a concave mirror and a projection surface of a nonlinear optical element on the fundamental wave of the emitting light than to the light higher harmonics. CONSTITUTION:The front edge surface 1b of a semiconductor laser 1 is selected to have a low reflectance for the outgoing light, and to have a high reflectance for the second higher harmonics. Further, each reflectance for the outgoing light of the laser 1 of a nonlinear optical crystal 3 and the second higher harmonics is made sufficiently small. The edge surface 5a of a concave mirror 5 is selected to have a high reflectance for the fundamental wave of the outgoing laser beam, and to have a low reflectance for the second higher harmonics. The laser beam generated in the laser 1 is amplified in a light resonator device, and directly inputted into the optical crystal 3. Accordingly, the need of a coupling optical system is obviated, and the dimension of the whole device can be reduced. Almost all the parts of the outgoing laser beam which is inputted into the optical crystal 3 is converted to the second higher harmonics A, and taken outside as the beam B parallel to the laser optical axis C through the concave mirror 5. Since the conversion efficiency from the outgoing laser beam to the second higher harmonics increases, the large output is permitted without increasing the dimension of the device.

Abstract: PURPOSE:To enable a tracking servo system to operate stably by making it operate according to a position detection signal to show the position of a movable optical system when the tracking servo system comes impossible to operate normally by a disturbance. CONSTITUTION:When some disturbance is given to the tracking servo system during operation, a signal to traverse a track appears in the output 104 of a differential amplifier. This is detected by a window comparator 109, and the number of times of traversing the track is counted by a counter 110, and when it reaches the prescribed number of times, a latch circuit 111 is held. Just then, the counter 121 is immediately held, and the signal which is free from DC offset and shows the position of the movable optical system 101 is outputted in the output of the differential amplifier 119. Thus, the position of the movable optical system 101 is controlled so that the output of a position detector 117 comes to be 0. Thus, the tracking servo system is never largely shifted from the position at the time when it operates normally.

Title: Production of multilayer electronic device
Inventor: NAKAZAWA CHIKASHI
IPC: B23K26/38
Filed: 1993-12-27
Abstract: PURPOSE:To obtain an electronic device whose size can be reduced while stabilizing the electric characteristics by providing irregularities on the inner surface of a groove during a groove making process. CONSTITUTION:A groove D1, substantially matching the printing pattern of a conductor layer, is made on the upper surface of a green sheet S at a predetermined depth. The inner face of the groove D1 is provided with irregularities D1a. The groove D1 is made by projecting a normal pulse laser light from a laser light source, e.g. a YAG laser, to a mask having a transparent part analogous to the conductor layer, condensing the transmitted light through a lens and focusing on the upper surface of the sheet S in the same shape as the conductor layer, and then fusing and evaporating the focused part. The depth of the groove D1 is regulated by the output laser light. This method reduces the size of the electronic device by decreasing the projection of the conductor layer by an amount corresponding to the depth of the groove. Furthermore, the density is prevented from increasing at the part of the sheet touching the conductor layer by lessening the stress at the time of pressing thus avoiding fluctuation in the permeability after firing.

Title: Liquid-level gage
Inventor: WATABE YASUHIRO
IPC: G01F23/22
Filed: 1989-12-21
Abstract: PURPOSE:To improve thermal efficiency, to make response speed quick and to make measurement accurate by providing a heating element on one surface of a ceramic substrate, laminating an insulator layer and a superconductor layer, and obtaining the multilayered constitution. CONSTITUTION:An oxide superconductor and a heating element 3 are formed on a ceramic substrate 2. The critical temperature of the conductor in liquid gas is utilized, and the position of a liquid surface is detected. At this time, an insulator layer and the oxide superconductor are laminated as a film constitution on the upper surface of the substrate 2 including the heating element 3. The heat from the heating element 3 is transferred into the liquid gas through an insulator film 4 and an oxide superconductor film 5. At this time, since the insulator and the superconductor have the film constitutions, heat exchange between the heating element 3 and liquid nitrogen or nitrogen gas is quickly performed. The response speed is quick, and the measured result is accurate. Since one surface of the heating element 3 is the thick substrate 2 on the other hand, the substrate acts as a heat insulating material, the flow of the heat into this direction is less and the thermal efficiency into the opposite surface becomes excellent.
