Title: Positioning of mask and wafer
Inventor: SUGISHIMA KENJI
IPC: H01L21/027
Filed: 1985-06-17
Abstract: PURPOSE:To detect easily the maximum clear-cut luminance and to enable to execute the correct positioning of a mask and a wafer by a method wherein a laser beam having a wavelength of a length of one-second of the interval between the mask and the wafer is made incident on the FZT, which is provided on the lower surface of the mask. CONSTITUTION:This positioning method is aimed at eliminating the mutual interference the incident wave and the reflected wave, which generates in the interval between a mask 11 and a wafer 13, by projecting a laser beam (lambda= several mum-several tens mum) 15 having a wavelength of a length of one-second of the interval between the mask 11 and the wafer 13 on the upper surface of the mask 11. As the interval between the mask and the wafer is normally 1mum-50mum, laser beams having the oscillation wavelengths (lambda) shown in the table are included in the laser beam having the wavelength of a length of one- second of the interval. The distribution of the luminance of a reflected light 16 to the interval between the mask and wafer becomes an acute luminance intensity distribution. By selecting the interval between the mask and the wafer, which corresponds to the maximum luminance in the distribution, the correct interval between the mask and the wafer can be found out.

Filed: 1990-05-24
Abstract: PURPOSE:To provide an identification power in a recording layer itself and to prevent forgery, falsification by forming a marble pattern of a plurality of recording materials having different output characteristics on a recording layer. CONSTITUTION:A magnetic recording layer 20 is formed with a marble pattern of a magnetic material 22 having low coercive force and a magnetic material 24 having high coercive force. That is, the material 22 having liquid state regulated to include low viscosity and low coercive force is contained in a predetermined vessel 40, and the material 24 having liquid state regulated to include high viscosity and high coercive force is introduced from other container 42 to the vessel 40. Then, an agitating rod 44 is agitated as required. Since the material 24 has different viscosity from the material 22, they are not completely mixed even if they are agitated. Thus, magnetic materials in which the materials 24, 22 are roughly mixed is fed on a board 10 to be coated, and dried to form the layer 20 having an arbitrary, undefined marble pattern.

Title: Mos transistor analog switch
Inventor: AKITAKE ISAO
IPC: H01L27/08
Filed: 1980-09-26
Abstract: PURPOSE:To prevent destruction of an MOS transistor to be caused by application of a large amplitude input signal by a method wherein a resistor is inserted in the base output end of a parastic transistor or in a negative electric power source circuit, and the take out point of a collector region is separated far away from a P-WELL layer being the the base region. CONSTITUTION:The resistor 13 is connected to a back gate terminal 1d, and the negative voltage source 3 is connected to the back gate terminal 1d through this resistor. The take out point of an Ep layer 5 being the collector region of the parasitic NPN transistor TR9 is set at the position separated far away from the P-WELL layer 7 being the base region. The P-WELL layer is formed by making P type Si to diffuse in a grown epitaxial layer, and it becomes to the same result with insertion of a resistor 14 between the take out point of the layer 6 and the collector of the TR9. Accordingly even when the input signal of large amplitude level is applied to an emitter 1a, because the current to flow in the TR9 is limited by the resistors 13, 14, the MOSTR is not destroyed.

IPC: G06F17/21
Filed: 1990-05-22
Abstract: PURPOSE:To point out only a position which is possibly wrong and to reduce the load on a user by detecting partial character strings, which are used only once among partial character strings counted by a partial character string counting means, as a wrong word. CONSTITUTION:A document is divided by a document dividing means 1 at change points between two kinds of characters, i.e. a change point from KATAKANA(square form of Japanese syllabary) to other characters and a change point from other characters to KATAKANA. Then the partial character string counting means 2 counts how many times the same character string is used in the document as to only partial character strings consisting of only KATAKANA. Then it is judged whether or not the counted character strings in KATAKANA are used only once and the partial character strings in KATAKANA which are used only once in the document are recognized as wrong words. When the partial character strings in KATAKANA which are counted are used only once in the document, an error detecting means 3 displays the detected wrong words to the user. Consequently, only positions which are possibly wrong are pointed out and the load on the user is reduced.
