Title: Semiconductor memory device
Inventor: BABA FUMIO
IPC: G11C7/00
Filed: 1987-03-10
Abstract: PURPOSE:To reduce the occupied area of a data register as few as possible with keeping a time required for the transfer of a data, by setting the number of bits of the data register at a necessary minimum number judging from the time required for the transfer of the data. CONSTITUTION:A prescribed number of data registers to input/output a memory data in order asynchronously to each other based on the supplying of a serial clock are provided. In such a case, the number of bits of each data register (shift register 31 or 32) is set at the number exceeding the number in which the number of the data registers is multiplied by a value obtained by dividing the time to transfer the data from a memory cell 1 to the data register or the data from the data register by a cycle period, corresponding to the number of the data registers. In such a way, it is possible to secure the minimum time required for the transfer of the data also reducing the occupied area of the data register as few as possible.

Title: Aligner
Inventor: TORIGOE MAKOTO
IPC: H01L21/30
Filed: 1987-03-10
Abstract: PURPOSE:To detect a mark for positioning accurately and rapidly by changing the position of a substrate when a film is removed through a film removal means and when the mark is detected through a mark detecting means. CONSTITUTION:A substrate 14 is displaced previously so that a light irradiation region for removing a photoresist on the substrate 14 is brought onto a light transmission section, to which a pattern is not formed, on the substrate 14 on light irradiation for removing the photoresist. The substrate 14 is shifted where capable of positioning by an optical system and positioning marks 14a-1, 14a-2, 16a-1, 16a-2 on positioning. The substrate is moved during that time by driving a substrate stage 30 by a substrate stage driver 31 by a command from a CPU 40. When an XY interferometer is used for measuring the position of the substrate at that time, the movement of the substrate can be controlled with precision sufficient for positioning after light irradiation for removing the resist. Accordingly, the adverse effect of a photosensitive body film at the time of positioning in an exposure device is eliminated and the substrate can be positioned accurately, thus improving throughput.

Title: Process controller
Inventor: TERAUCHI YUKIO
IPC: G05B13/02
Filed: 1996-03-11
Abstract: PROBLEM TO BE SOLVED: To prevent the output of the parameter of a compensation operation part from changing even if it is changed and to prevent a manipulated variable from changing by adding parts having delay elements before and behind a compensation element. SOLUTION: A previous target value SVn-1 from the delay element 41 is inputted to the operation part 42. The operation part 42 obtains a difference δSV between the target values SVn and SVn- and only the difference δSV is inputted to the compensation element 10. In the compensation operation part 10, a compensation operation is executed only on the change quantity of the target value SV in accordance with the content of H(s), and the operation result δR of only the change quantity of this time is outputted. Output Rn-1 is added to the output value δR in an addition part 43, and it is outputted as the reference Rn of this time. When there is no change in the target value, the difference becomes δ SV=0. Consequently, the operation result δR is not affected in spite of the form of the H(s) type of the compensation operation part 10.

Title: Information carrier and information reader
Inventor: SANO KENJI
IPC: G06K17/00
Filed: 1996-03-11
Abstract: PROBLEM TO BE SOLVED: To effectively prevent forgery in a method different from an existent manner by providing opaque coating film consisting of high polymer material and liquid crystal on a carrier recording information so as to cover the information. SOLUTION: A secret printed part 2 such as a bar code is formed on the surface of the carrier 1 such as a card. The coating 3 including the high polymer material and liquid crystal is provided on the carrier 1 so as to cover this printed part 2. The thickness of the coating 3 including the high polymer material and liquid crystal is set to sufficiently generate scattered light under the condition of using the carrier 1 and to secure such opacity as prevents printed part 2 from being identified, more than 30μm, for example. Because of scattering light under a normal condition, the coating 3 seems to be colored in white or chromatic color so that the printed part at a backing is not seen. Consequently it is not known that secret information exists there. In addition, as high printing technique is not necessary to use, a cost is reduced.

IPC: B28D1/30
Filed: 1999-03-02
Abstract: PROBLEM TO BE SOLVED: To enable a large stone to roll well, and effectively manufacture a large cobble stone having no corners. SOLUTION: The apparatus includes a rotor 10 rotatably provided around a horizontal rotating shaft, having a throwing inlet, and housing a large stone thrown from the throwing inlet, and a driving motor 10M for rotating the rotor 10 around horizontal rotating shaft; which the inside peripheral face is a polygonal cylinder. When the rotor 10 is rotated by the motor 10M, since a large stone rises to the some degree at the inside peripheral face of the rotor 10 and subsequently falls down for all the time of rotation of the rotor 10, the large stone continues to roll well in the inner part of the rotor 10, as a result, a large cobble stone can be manufactured efficiently having no corners.

Abstract: PURPOSE:To provide an Auger electron spectrometer capable of exact correction of analysed position and in which no drift of the measured location takes place in the case where analysis of a micro portion equal or less than 1mum, in which the intensity difference relative to ambient intensity is so small that image recognition being difficult, is performed, or in the case of the thickness direction analysis where the surface condition varies due to sputter or the like during analysis, upon the surface analysis of semiconductor devices or the like. CONSTITUTION:A vacuum vessel 1 of an AES chamber is coupled with a vacuum vessel 2 of a FIB chamber via a gate valve. As specimen stages 5 and 6 are mounted on the vacuum vessels 1 and 2, and since respective specimen stages 5 and 6 capable of five kinds of independent motions correspond with a computer 13 one to one, it is easy to search for an analysing location of an AES, and image recognition of the analysing location can be performed with the AES aiming at the mask put by the FIB.

Filed: 1996-02-06
Abstract: PROBLEM TO BE SOLVED: To enhance the insulating capability of a ceramic far infrared radiation heater by forming an insulating film having almost the same composition as the heater on the surface of the ceramic far infrared radiation heater. SOLUTION: A ceramic far infrared radiation heater contains aluminum silicate as a main component and a silicon compound as a conductive material. A 1-50μm thick insulating film containing A12 O3 as a main component is formed on the surface of the heater. Since the insulating layer and the conductive layer of the far infrared radiation heater have the almost the same composition, the coefficient of thermal expansion of both layers is almost equal, the separation of two layers during use is prevented, and the heater can stably be used to the temperature of about 600 deg.C.

Title: Photo coupling device
Inventor: HAMAZAKI YUUJI
IPC: G02B6/26
Filed: 1979-05-02
Abstract: PURPOSE:To improve coupling efficiency and reliability by reducing the outside diameter of the end part of the photo detecting part of a guide fiber and forming the end to spherical shape in the photo coupling device in which a light emitting diode and an optical fiber are coupled by way of an optcial guide fiber. CONSTITUTION:An optical guide fiber 11 of a diameter larger than that of an optical fiber 13 is provided between the light emitting part 8 of a light emitting diode 7 and optical fiber 13 and is connected to the optical fiber 13 by means of a connector 12. The end part of said optical fiber 11 opposing to the light emitting part 8 is made smaller in outside diameter and is formed to the shape which has the optical radius determined by the diameter of the light emitting part 8 and the refractive index, etc. of the core 15 and clad 16 at said end. In the case where the end part of the optical guide fiber is not reduced, the radius of the sphere at the end must be made larger than the radius of the guide fiber and therefore it does not become optimum radius. Hence, the above-mentioned method improves the coupling efficiency and improves reliability as well becuase of the absence of any moving parts such as lenses.
