Title: Formation of sos substrate and semiconductor device using substrate thereof
Inventor: MORIYASU YOSHITAKA
IPC: H01L27/12
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To improve the flatness of an Si film readily after growth without later processing such as solid-phase epitaxial process, by forming a terrace structure on a sapphire substrate by heat-treating the sapphire substrate, and growing the silicon from the step part of the terrace structure. SOLUTION: The surface of a sapphire substrate 1 undergoes heat treatment, and the substrate having surface pattern of a terrace structure with a step 2 in an atomic layer order is formed. As the heat treatment, for example, the method for annealing the sapphire substrate in atmosphere and the method of homo-epitaxial growing of the sapphire by a crystal growing method and the like are effective. Then, Si is eptaxially grown on the sapphire substrate 1. The Si is grown with the step 2 formed on the sapphire substrate 1 as the starting point. That is to say, the crystal nucleus of the Si is formed at the step part 2 of the substrate 1. When the growing of the Si is further continued, the crystal nuclei are mutually combined, and the quantum thin lines connected in the linear shape are obtained.

Filed: 1999-09-09
Abstract: PROBLEM TO BE SOLVED: To prevent a third person from performing an illegal security release operation by designating 2nd data from prescribed data on the basis of a prescribed generated random number when deciding that a 1st input exists, deciding the existence/absence of 2nd data input to a security state switching means and controlling a security state. SOLUTION: A device first decides whether 1st data is inputted. That is, the inputted 1st data are compared with corresponding data preliminarily stored in a storing part 11, and when they are the same, the device decides that the data is inputted. Next, when a controlling part 6 decides that the data coincide with each other in comparison decision, the part 6 selects specified data as 2nd data from a plurality of pieces of data which are made to correspond to individual identification information included in the 1st data and are stored in the part 11 on the basis of the random number obtained from a random number generating part 10. Subsequently, an input request for the 2nd data is notified from a displaying part 5 or a sound outputting part 8. Then, when the part 6 decides that the 2nd data is inputted within an input allowable time, the security state is released.

Patent JP-H03118621-A (JP)
Title: Current mirror circuit
Inventor: UEDA TOMIO
IPC: G05F3/22
Filed: 1989-09-29
Abstract: PURPOSE:To obtain a current mirror circuit which can always keep a constant ratio between an input current and an output current by setting optionally the collector voltage of a 1st TR at a level equal to the collector voltage of a 2nd TR. CONSTITUTION:A base-earthed amplifier of a TR3 uses an in-phase amplifier and therefore the collector voltage of the TR3 rises when the collector voltage V1 of a TR1, i.e., the emitter voltage of the TR3 rises. Thus the base voltage VB of the TR1 also rises to increase the collector current IC of the TR1. When the current IC increases, the voltage V1 drops with the voltage drop of the current IC. Thus the first voltage level has substantially no change. When the base-emitter voltage is referred to as DELTAV, V1=V3+DELTAV is satisfied. If it is supposed that the base current IB is equal to the emitter current IE of the TR1, I1/I2=(2(1+1/hfe3)+hfe1)/hfe2 is satisfied. That is, the V1 can be optionally set based on the V3 and therefore the ratio between the I1 and the I2 can be kept constant when the V1 is set equal to the V2.

Title: Thermal expansion adjusting material
Inventor: YAMAGUCHI KENJI
IPC: H01L21/52
Filed: 1988-10-12
Abstract: PURPOSE:To improve a solderability while the superior thermal expansion adaptability of an Hf layer with a ceramics layer is maintained intact by a method wherein a thermal expansion adjusting material is constituted in such a way that copper layers or copper alloy layers are respectively cladded on both surfaces of the Hf layer and the thickness ratio of the copper layer: the Hf layer: the copper layer is set at a specified range. CONSTITUTION:Copper plates or copper alloy plates 1b and 1b, whose thicknesses are almost equal, are respectively cladded on both surfaces of a hafnium(Hf) plate 1a and the plates 1a, 1b and 1b are constituted into a thermal expansion adjustable clad material (a thermal expansion adjusting material) 1. The plate thickness ratio of the copper plate: the Hf plate: the copper plate is set at a range between 1:500:1 (about 0.4% of the coating volume percentage of Cu) and 2:1:2. As this result, a layer, to which a silver solder layer 2 comes into contact, is not the Hf layer but is changed into the copper layer 1b and a difference between this silver soldering and a silver soldering with the copper layer itself is eliminated. Thereby, a significant improvement and a stabilization of a solderability can be accomplished without impairing the thermal expansion adaptability of the Hf layer with an Al2O3 ceramics layer.

Filed: 1991-10-03
Abstract: PURPOSE:To prevent assembly failure of viscous damper operating liquid sealing for absorbing torque fluctuation, and reduce seal sliding resistance so as to reduce driving force of a device and operate the device smoothly. CONSTITUTION:In a valve timing adjusting device, a viscous damper 17 is arranged in series in axial direction of a cam shaft 1 in relation to phase change mechanisms 5, 6, 11. Seals 27, 28 are arranged on the smallest diameter part of the viscous damper 17, and are so constituted as to carry out sealing by flat surfaces 10b, 13b perpendicular to the axial line.

Abstract: PURPOSE:To improve operation performances by a method wherein the torque and the slip speed of a motor and their differential value are converted into fuzzy language information and a signal obtained by calculating the weighted average of the results of required language rules near a fluctuating adhesion limit in accordance with the compatibilities to the rules is used to correct a motor torque instruction. CONSTITUTION:The output of a defuzzification means 13d which inverts a fuzzy expression into a definite expression again is used as a torque correction signal 113, which is a fixed torque correction value for obtaining high adhesion. Then the minimum value among the compatibilities of the magnitudes to a slip speed and the differential valve of the slip speed is employed to cut off the head part of the membership function of the torque correction value obtained from a control rule. The center of gravity of the membership functions whose head parts are cut off and which are corresponding to the respective control rules is obtained and the torque corresponding to the center of gravity is used as the fixed correction signal of a torque instruction. With this constitution, the operation performances which provide an excellent average acceleration, driving comfort and so forth can be obtained.
