Patent JP-S60128622-A (JP)
Title: Etching method
Inventor: SUNAMI HIDEO
IPC: H01L21/3215
Filed: 1983-12-16
Abstract: PURPOSE:To reduce the generation of damage on the base substrate as well as to form a microscopic pattern by a method wherein a converged ion beam is made to irradiate on the material to be processed, and an isotropic etching is performed giving few damage on the substrate by changing the speed of etching by deviating the density of irradiation of the ion beam. CONSTITUTION:An SiO2 film 2 is formed on an Si substrate 1. Then, when a mu- ion beam 4 of phosphorus is made to irradiate, a phosphorus mu-iondoped layer 3 is formed. Subsequently, an etching is performed on the whole surface using an etchant which is popularly named as P-etchant. The etching speed of said P- etchant varies sharply by the density of phosphorus contained in SiO2. For example, when phosphorus of 15mol% is implanted, the speed of etching to be performed on SiO2 is increased to about hundred times. Accordingly, the phosphorus-implanted pipelike layer 3 alone is etched, and a very fine etching hole 5 can be formed.

IPC: G01S7/52
Filed: 1991-09-17
Abstract: PURPOSE:To enable an unneeded load which is applied to a feeding screw to be reduced by mounting one edge of an elevation bracket to an elevation pipe and holding the other edge so that a female screw member can slide in a direction of radius of the elevation pipe. CONSTITUTION:An elevation bracket 7 consists of a base part 71 which is mounted to an upper edge of an elevation pipe 8 and a connecting joint 72 which allows a screw mounting part 102 where a collar part 103 is fitted to slide in left and right directions freely. A feeding screw 5 rotates in clockwise and counterclockwise directions according to a rotary direction of a motor and a female screw 101 moves up or down according to its rotation. The female screw mounting part 102 can slide in a cutting part of the connecting joint 72 of the bracket 7 via the collar part 103 freely. For rotation of an axis core of a screw 5, a bracket part 104 of the collar part 103 contacts the connecting joint 72 for preventing rotation, thus eliminating a need for the pipe 8 and the screw 5 to be moved in parallel and hence preventing an unneeded load from being applied to rotation of the screw 5.

Abstract: PURPOSE:To enable to mold a lens with high accuracy at low cost by a method wherein a lens is molded in the interior of a lens barrel and consequently the lens and the lens barrel are made into an integral body under the state that the center lines of the lens and of the lens barrel coincide with each other. CONSTITUTION:Firstly, resin material 15 and a spacer 19 are heated up to the predetermined temperature. Secondly, pressure P is applied through the mold surfaces 13 and 14 of an upper punch 11 and of a lower punch 12 to the resin material 15 in order to transfer the predetermined lens surface form onto the softened resin material 15. Thirdly, when the whole molding block is cooled, the predetermined lens thickness is held in a lens 18 by means of the spacer 19. Because the lens 18 is hardened after the resin material excess for the volume necessary for the form of the lens 18 flows in through holes 17, the highly accurate lens surface form and lens thickness are formed at all times. In addition, because the volumetric fluctuation of supplied resin material is absorbed in the formed of resin quantity flowed in the through holes, an integrally molded lens with few fluctuation and stable accuracy can be obtained.

Filed: 1995-08-24
Abstract: PROBLEM TO BE SOLVED: To obtain more exact walking speed without using any instable step to affect the walking speed by instructing a walking pitch for walking at desired speed by inputting the walking speed and the sex, height, weight and age of a user. SOLUTION: A fixed-speed walking instructing device instructs the walking pitch for walking at the desired speed by inputting the walking speed and the sex, height, weight and age of a user. In usual walking, the more the walking pitch is accelerated, the more the step is widened and the more the walking pitch is decelerated, the more the step is narrowed. The step is affected by the height, weight, age and sex of an individual and when the walking pitch is decided with these body features as parameters, the step of that individual is unitarily decided. By designating the walking speed and correcting it with the height, weight, age and sex of the user as parameters, the walking pitch corresponding to the user can be provided. The figure shows the graph of correlation between the measured value of the number of walking pitches and the calculated value of a man (a) and a woman (b).
