Title: Ophthalmoscope
Inventor: YAMASHITA AOMINE
IPC: A61B3/10
Filed: 1996-08-19
Abstract: PROBLEM TO BE SOLVED: To readily and instantly judge whether a measured value and its scattering are within or not in a previously given range, by outputting a signal to show it when the measured value about an examined eye coincides with a judegment condition to discriminate the value. SOLUTION: On beginning the measurement, a reflecting light obtained by a detecting optical system K12 of a measuring optical system K1 is processed through an analogue processor and a digital processor of a computing processing unit 20 and then a measured value is given by a numerical processor. The measured value is sent through a controlling unit 60 to a discriminating part for measured value of a discriminating unit 40, the discriminating part discriminates whether or not the measured value coincides with a discriminating condition previously stored in a measuring condition storing part of a memory unit 10 and sends the measured values together with the discriminating result signal to a controlling unit 60.  The controlling unit 60 sends the measured value to a measured value memory part in the memory unit 10 to store it and sends to a display apparatus driving circuit of an output unit 50 to make it display on a display apparatus 100.

Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To meet various working conditions with only one unit by making the best use of the heat loss tolerance capability of the unit owns. SOLUTION: High voltage and low voltage are switched and outputted by a transformer circuit 2A, and rectified and smoothed by a rectification and smoothing circuit 10, which are then inputted into a DC stabilization power circuit 20.

Title: Gallium.arsenic single crystal wafer and gallium.arsenic liquid phase epitaxial wafer
Inventor: MORIWAKE TATSUYA
IPC: C30B19/12
Filed: 1999-08-02
Abstract: PROBLEM TO BE SOLVED: To obtain good surface state while suppressing the formation of wedge structure at pn-interface by allowing a single crystal substrate comprising plural elements to have the surface inclining by a specified angle with respect to the  100} plane. SOLUTION: A single crystal GaAs substrate is used for producing an epitaxial wafer having pn-junction by a liquid phase epitaxial method using Si as a dopant. The single crystal GaAs substrate is a GaAs single crystal wafer and has the surface forming an inclination angle θ of 0.02 to 0.2 deg. with respect to the  110} plane. The more the substrate plane orientation deviates from the  110} plane, the smaller the abnormality in pn-junction becomes. When the value of the θ is higher than 0.02 deg., the formation rate of pn-junction having the wedge structure is markedly decreased. However, when the value of the θis higher than 0.24 deg., the epitaxial surface becomes coarse and it becomes difficult to form an electrode, or the like.  In order to suppress the formation of the wedge structure at the pn-interface and to obtain a good epitaxial wafer, it is preferable to cut down so that the substrate plane orientation forms an angle of 0.02 to 0.2 deg. with respect to the  100} plane.
