Patent JP-H05235403-A (JP)
Title: Optical semiconductor device
Inventor: ADACHI HIDETO
IPC: H01L31/14
Filed: 1992-02-19
Abstract: PURPOSE:To arrange a photo-transistor to the upper section of a laser diode, and to realize a signal light transmission type optical semiconductor device, in which the position of the input and position of output of a signal are equalized, by using a lattice mismatch graded layer or a P-type substrate. CONSTITUTION:The arrangement of a laser diode and a photo-transistor is exchanged to upper and lower sections, and an electrode functioning as a reflecting mirror in combination is not disposed to a laser diode section. A lattice mismatch graded layer generating extremely large leakage currents is arranged between the P-type mirror section or the laser diode and the N-type collector layer section of the photo-transistor so that breakdown strength characteristics are not generated by a P-N junction generated between the P-type mirror section and the N-type collector layer section at that time. An electrode in the upper section of an emitter layer is formed in a shape having a window, into which signal light is input. Accordingly, a transmission type can be realized as the positions of the input and output of signal light are left as they are equalized.

Title: Cohesive soil banking method utilizing natural cold during winter season
Inventor: SAKAI YOSHIHIDE
IPC: E02D17/18
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To easily bank cohesive soil during the winter season by freezing the upper part of a banking subsoil, using cold energy at nighttime for increasing a prior- consolidation load or strength, and utilizing the retained heat of filling soil removed from a cut part for facilitating the fusion of frozen soil, as well as the convergence of the thawing and sinking thereof. SOLUTION: A banking ground 2 is first formed at a banking site 1. When the surface of banking is exposed to the cold air at nighttime, the banking ground 2 comes to form an un-frozen part 2a and a frozen part 2b. Also, when a freezing process develops, pore water in un-frozen soil moves toward frozen surface, and the un-frozen part 2a becomes over-consolidated, compared with a state at a banking process, and is compressed. Furthermore, when suitable frozen thickness is obtained, a banking ground 3 is formed on the frozen part 2b. As a result, the retained heat of the banking ground 3 is transmitted to the frozen part 2b and this frozen part 2b is thereby caused to thaw, though to a small extent. This process is repeated to form the required height of banking subsoil.  According to this construction, the strength of both frozen soil and un-frozen soil increases, thereby restraining over-compaction or unstable banking at a banking process.

Filed: 1991-01-31
Abstract: PURPOSE:To enable interference to be measured easily by adjusting a peak value of a brightness level of an interference fringe of a body to be inspected entering an image pick-up element. CONSTITUTION:An amplitude-modulation means 2 such as a 1/2 wavelength plate and an LCD is inserted into a light path of an interferometer optical system 1 and an image pick-up element 3 where an interference fringe of a body to be inspected enters. An output of the image pick-up element 3 is converted into digital data by a frame memory 4, a peak value detection circuit 5 detects a peak value from a brightness level of this output, and the detected peak value is output to a comparator 7. The comparison circuit 7 compares this peak value with a target setting value from a threshold setting circuit 6 and then outputs a command signal corresponding to the comparison result to a control means 8. The control means 8 adjusts the amplitude-modulation means 2 within the light path so that the peak value of the interference fringe entering the image pick-up element 3 becomes the target value. Since the quantity of light of interference light entering the image pick-up element 3 is adjusted directly, control can be made positively.
