Title: Semiconductor device
Inventor: KIMURA TAKEMI
IPC: H01L21/768
Filed: 1988-06-13
Abstract: PURPOSE:To prevent the short between layers by a method wherein, in the case of opening a contact hole on a wiring layer, a lower wiring layer is arranged in this region. CONSTITUTION:When a contact hole is opened on a first aluminum wiring 5, and said layer is connected with a second aluminum wiring 7, an electrode composed of polycrystalline silicon 3 is formed under a region where the contact hole is opened on the first aluminum wiring 5. Thereby, even if the contact hole and the first aluminum electrode 5 of a substratum are misaligned by positioning shift with each other, the progress of the etching of the contact hole is stopped at the part of the polysilicon, since the polysilicon electrode 3 exists under the contact hole. Thereby the short between the semiconductor substrate 1 and the second aluminum wiring 7 can be prevented.

Title: Automatic winding of wire and winder therefor
Inventor: TANAKA AKIHIRO
IPC: B65H59/36
Filed: 1985-07-03
Abstract: PURPOSE:To obtain automatic winding with no deformation of winding when winding a wire on a tapered take-up bobbin by inverting the moving direction of a traverser when the winding diameter exceeds a predetermined value during movement of the traverser from the smaller-in-diameter portion of the take-up bobbin to the larger-in-diameter portion. CONSTITUTION:In order to wind up a wire 1, the smaller-in-diameter end of a take-up bobbin 2 is determined to be the start position S and one end of the wire 1 is attached to the position S. As the traverser 4 is moved from the winding start position S to the larger-in-diameter portion of the take-up bobbin 2 during rotation of the take-up bobbin 2, the winding diameter of the wire 1 gradually increases, so that the winding travel speed of the wire 1 increases and the tension of the wire 1 in the wire travel line increases. That change of tension causes dancer rollers 7 to be displaced in position in such a direction as to reduce the rotating speed of the take-up bobbin 2. The displacement in position is detected by a proximity switch 8 and used through control means 9 to invert the traverser driving mechanism under control, so that the traverser 4 is inverted to move toward the winding start position S.

Filed: 1993-06-17
Abstract: PURPOSE: To automatically determine the thickness and the composition of respective layers of a multilayer structure by converting a function corresponding to a reflected strength signal into a function corresponding to a strength signal expressed as a function of the thickness in the multilayer structure. CONSTITUTION: The layers of a multilayer structure body 10a formed on a substrate 100 show slightly different refractive constants in respective interfaces. The function f(θ) corresponding to the reflection intensity signals measured as a function of the glancing angle θ (the supplementary angle of the incident angle), which is limited by the minimum angle value θmin and the maximum angle value θmax respectively, is converted into a function (d) corresponding to the formulated intensity signals as a function of the depth of the structure body 10a. The depth of respective interfaces d1 , d2 ,... dn of the structure body 10a and the relevant reflection intensity are directly displayed by the obtained function (d).  The angle range from θmin to θmax can be measured as a function of the glancing angle by measuring the intensity of the reflection from a sample to be measured by using an x ray diffractometer.

The noncondensed fraction is absorbed and collected with absorbing water to obtain an aqueous solution composed mainly of acrylic acid, acetic acid and water. The solution is supplied to a distillation column having a recovery zone with a theoretical plate number of >=10 and distilled in the presence of an azeotropic agent. An azeotropic composition composed essentially of the azeotropic agent and water and free from acrylic acid and acetic acid is distilled off from the column top, and a mixture composed mainly of acrylic acid and acetic acid and free from the azeotropic agent and water is separated from the bottom of the column. The water separated from the distillate of the column top is recycled as the absorbing water. Acrylic acid can be produced economically by a pollution-free closed system.

Title: Automatic numerical control programming device
Inventor: SAKAI HIROKO
IPC: G05B19/4097
Filed: 1986-06-23
Abstract: PURPOSE:To secure a tool route for 5/2-dimensional processing which is parallel to the tool moving plane by calculating the tool route data based on a calculated tool shift section curve. CONSTITUTION:A reference shift section plane 11R is divided based on the processing route intervals and the information on the desire to unify said intervals. Thus a first dividing point 11S1 is obtained. Then a pick-feed operation is applied to the point 11S1 to extract the fixed axis coordinate value Z1 of the point 11S1. Based on the value Z1, the basic section curve deformation values Aa1-An1 are calculated on other shift section curves 11a-11n. A basic section curve 10 is set opposite to each of curves 11a-11n by each amount of values Aa1-An1 to obtain deformation points Ba1-Bn1. These points are smoothly connected with each other to obtain a tool shift section curve. Then it is decided whether the processing is through or not with the point 11S1. If not, the processing is repeated.

Title: Device for detecting flow state in transport pipe
Inventor: KOISHI YOSHITAKA
IPC: B65G43/08
Filed: 1996-05-15
Abstract: PROBLEM TO BE SOLVED: To positively detect a flow state in a transport pipe by providing a vibration sensor disposed at an external wail of a transport pipe, and an output device to which the vibration sensor is connected. SOLUTION: The grade data of vibration amplitude outputted by a vibration sensor 3 is obtained, and a boundary state in need of maintenance and inspection is found out while considering the data. The grade of vibration amplitude in this boundary state is then determined, and this grade of a vibrating state is made the set value. The vibration amplitude at the time of a satisfactory transport state is larger than that at an unsatisfactory transport state. A signal outputed from a comparator 4 is generally a pulse signal. When transported material flows smoothly in a transport pipe P, an output device 5 is operated receiving the pulse signal outputted from the comparator 4, but when the transported material ceases to flow smoothly in the transport pipe P, the comparator stops outputting the pulse signal, so that the output device 5 is not operated.

Abstract: PROBLEM TO BE SOLVED: To perform a packaging without swelling and slacking by a method wherein a sheet material is bent while an upper downward bending plate, a lower upward bending plate, and an upper inward bending part, which are being urged, are being slidably brought into contact with. SOLUTION: In an upper bending downward device 131, when an upper bending downward plate 144 is driven to be lowered, the leading end of the bending downward plate 144 which is urged by a spring, bends the upper overhang part of a sheet material, downward, and a bent corner part of the sheet material 4 is angled.

Title: Formation of metal back of cathode-ray tube
Inventor: TERADA KATSUMI
IPC: H01J29/28
Filed: 1983-08-10
Abstract: PURPOSE:To prevent a blistering phenomenon of a metal reflecting film by specifying a temperature gradient condition of a baking process. CONSTITUTION:In the baking process for forming a metal reflecting film for metal back, a heating gradient in the large region of a weight decreasing rate on the thermal weight analytical curve of an intermediate film is set up to be remarkably slow compared with the starting time. The heating gradient is made to be 2 deg.C/min in the region of 250-290 deg.C, in which thermal decomposition of a sensitive bonding agent is accelerated, and in the region of 335-405 deg.C, in which the thermal decomposition of an intermediate film is accelerated. The temperature gradient condition can be made slower or a heating curve, in which constant temperature heating is performed for a fixed time in the region showing sudden thermal decomposition while intermittently raising temperature after diffusion of evaporation gas, can be adopted. Thereby, a blistering phenomenon of the metal reflecting film due to sudden evaporation of the intermediate film can be prevented.
