Title: Relative distance measuring apparatus
Inventor: ARAI IKUO
IPC: G01C7/02
Filed: 1999-06-23
Abstract: PROBLEM TO BE SOLVED: To provide a relative distance measuring apparatus which can measure time change or spatial change of an objective distance with high speed, high precision and high distance resolution, by using a radiowave like microwave or a sound wave. SOLUTION: A microwave frequency-modulated in a wide band is radiated. Its receiving signal and transmitting signal are mixed. A beat signal E1 having a frequency and a phase corresponding to the microwave propagation distance is outputted from a mixer 26. Multiplications and total summations of the beat signal E1 and two orthogonal reference signals having a frequency corresponding to a specified distance are performed, respectively, and a ratio of the two total summations is obtained. From the ratio, a signal corresponding to the phase of the beat signal E1 is obtained. The time change or the spatial change of the signal corresponding to the phase is converted to the amount of time change or the amount of spatial change of an objective distance.

Abstract: PURPOSE:To obtain the magneto-optical recording medium having corrosion resistance and pitting corrosion resistance and excellent magnetic Kerr rotating angle and coercive force by forming a composite artificial lattice film laminated with Co-Pt artificial lattice films and Co-Pd artificial lattice films as a recording layer. CONSTITUTION:The Co-Pt artificial lattice films are formed by alternately laminating Co layers and Pt layers by sputtering on a substrate and further, the Co-Pd artificial lattice films are formed by alternately laminating Co layers and Pd layers by sputtering thereon. The composite artificial lattice film formed by laminating these films is used as the recording layer.

Abstract: PURPOSE:To quickly warm up this when the interior is cold, and negate a heat load increase quantity by solar radiation without making an occupant feel the cold after the interior is warmed up. CONSTITUTION:A variable GW is determined by a difference (Tset-Tr) between a preset temperature and an inside air temperature, and a value by multiplying a detecting value of a solar radiation sensoe by GW is set as a correction solar radiation quantity.

Filed: 1987-07-20
Abstract: PURPOSE:To realize high reliability and high efficiency, by forming a second low-concentration semiconductor regional layered film in a Schottky barrier semiconductor device so that a thickness of this film becomes larger in the order of the following regions; a third semiconductor region, a Schottky barrier region, and other regions. CONSTITUTION:A high-concentration N type region 6, where a Schottky barrier is formed, is formed on an N type semiconductor substrate 7, and a necessary low-concentration N type region 5 is formed in order to obtain a desired reverse voltage. Next, layers 3 and 4 in the low-concentration N type region 5 are adjusted in their thickness. The reverse voltage of the Schottky barrier semiconductor formed in this way is determined from a thickness 4 of a low- concentration N type regional layer under a guard ring region, and the forward voltage is determined from a thickness 3 of a low-concentration N type regional layer. The reverse voltage is controlled under the guard ring region in order to improve the endurance to breakdown. Accordingly the thickness 3 of the low-concentration N type regional layer is made smaller under the guard ring region than under the Schottky barrier region, so that the reverse voltage is necessarily determined under the guard ring region in composition of this device.
