Title: Phase difference plate, laminated polarizing plate and liquid crystal display device
Inventor: YOSHIMI HIROYUKI
IPC: G02F1/13363
Filed: 1999-02-08
Abstract: PROBLEM TO BE SOLVED: To solve problems of changes due to the phase difference by double refraction of a liquid crystal and to the viewing angle as well as of the dependence of these characteristics on wavelengths by using a combination of two or more kinds of phase difference films having different refractive index characteristics. SOLUTION: As for the phase difference plate, a combination of two or more kinds of phase difference films having different refractive index characteristics is used. The phase difference film used shows the refractive index characteristics of nx=ny>nz, nx>ny>nz, nx>ny=nz, nx>nz>ny, nx=nz>ny, nz>nx>ny or nz>nx=ny, wherein nx and ny are the principal refractive indices (nx>=ny) in the plane and nz is the refractive index in the thickness direction. Thereby, the wavelength dependence can be controlled by using the combination of the films having different wavelength dependence. By disposing the slow phase axes of the film in a crossing state, (pseudo) optical rotatory property can be imparted, and the problem of the difference in the double refraction characteristics depending on the aligned state of the liquid crystal can be solved.  Thus, not only changes due to the phase difference by double refraction of the liquid crystal or to the viewing angle but the wavelength dependence of these characteristics can be compensated.

Title: Bootstrap controller
Inventor: WATANABE YASUHIRO
IPC: G06F1/00
Filed: 1980-03-10
Abstract: PURPOSE:To realize common use of an input/output device by plural units of arithmetic processors and furthermore secure a loading of different programs, by transferring the number that identifies the different programs from plural arithmetic processors. CONSTITUTION:Each of arithmetic processors A1-An has a function to transfer the device number 1, control code 2 and identifying number 3 that selects the program to be stored in the storage device D to the controller C of an input/output device Z. When the key K is pushed in either one of processors A1-An, a loading or program is interpreted. Thus the timing circuit T works to produce the signals T1-T3, and then sends successively the number 1, code 2 and number 3 stored in the registers R1-R3 to the transfer line B via the gates G1-G3. The controller C receives the data sent by the timing signals T1-T3 to compare it with the number 1 and the set device number. If a coincidence is obtained, a request to the device Z is decided. Thus a reading request is given to the memory device D via the number 3 for selection of the program as well as the code 2.

Inventor: HYODO KAZUAKI
IPC: F02D41/00
Filed: 1987-02-12
Abstract: PURPOSE:To prevent the occurrence of unevenness in combustibility between cylinder sections, by a method wherein, based on a difference in response between a plurality of air-fuel ratio sensors, each mounted facing each of a plurality of cylinder sections, a control mode during feedback control is varied. CONSTITUTION:Each of air-fuel ratio sensor A1 and A2 is positioned facing each of a plurality of cylinder sections. Based on detecting outputs from the air-fuel ratio sensors A1 and A2, feedback control is effected on a fuel feed amount by means of an air-fuel ratio control means B so that an air-fuel ratio of air-fuel mixture in each cylinder section is adjusted to a given value. Based on output signals from the air-fuel ratio sensors A1 and A2, a deference in response between the air-fuel ratio sensors A1 and A2 is detected by means of a response difference detecting means C. Based on the deference in response, a response difference correction means D causes the air-fuel ratio control means B to vary a control mode so that an air-fuel ratio between the cylinder sections is reduced.

Abstract: PROBLEM TO BE SOLVED: To normally process images even when a paper size and an image size are not coincident, by operating a magnification so that images can be printed properly to a paper when the paper size is different from the image size, and enlarging or reducing image data on the basis of magnification data. SOLUTION: A transmission permission signal for image data is sent to an image-processing apparatus which sends an order for printing, copying (step 10). When a paper size and an image size do not agree, a suitable magnification is operated from the paper size and image size (step 18). A signal indicating a size disagreement (step 19) and magnification data are sent to the image- processing apparatus. When the paper size stored in a printer part is different from the paper size (image size) indicated by the image-processing apparatus, the image-processing apparatus sends again image data enlarged or reduced on the basis of the operated magnification data.

Title: Free-cutting steel powder
Inventor: YAMAGAMI TOORU
IPC: B22F1/00
Filed: 1979-03-14
Abstract: PURPOSE: To obtain free-cutting steel powder in which the desulfurization does not occur in sintering, by containing a specified amount of S in the steel, and containing Mn slightly more than the Mn amount required to balance with the S amount as MnS, and grinding by atomization.  
     CONSTITUTION: S is contained in steel by 0.15W0.5wt%, and Mn is added by excess of 0.3wt% than the amount of Mn required to balance with said S as MnS. This steel is ground by atomization, and raw material steel powder for sintered product is obtained. When atomizing, oxidation of Mn which may reduce the MnS does not occur, and the excess Mn prevents decomposition of MnS and oxidation of Mn. The quantity of S necessary for free-cutting property exists in the form of MnS, so that deterioration of free-cutting property of sintered product due to desulfurization of S and damage of sintering furnace due to desulfurized S may be prevented.

Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To reduce transferred data quantity when pieces of data of characters and graphics the shape of which is expressed by control points are transferred to an image output device such as a printer. SOLUTION: In an OS(operating system) to supply font data to a printer driver, control point coordinates of an outline font are managed by a source format 10 in a fixed decimal point form of an integer part with 16 bits and a decimal part with 16 bits. Each control point coordinate is converted into a transfer format 14 for small size when character size of a font is the size so as to be stored in the transfer format 14 for small size in the fixed decimal point form of the integer part with 10 bits and the decimal part with 6 bits in the case of transferring the font data acquired from the OS to the printer by the printer driver.  When the control point coordinates are in large size so as not to be stored in the transfer format 14 for small size, each control point coordinate is converted into a transfer format 12 for large size in a floating point form with 32 bits which are conventionally used.

Abstract: PURPOSE:To prevent a received signal from entering a transmission system, by connecting input and output parts of modulator and demodulators and connecting the output part of the reception system and the input and output parts of a modulation and demodulation part through an attenuator. CONSTITUTION:A signal from a modulator and demodulator (MODEM)10 is transmitted to an optical receiver 13 through an optical transmitter and receiver 11 and an optical fiber 12. The received signal is converted into an electric signal 1, which is attenuated by the attenuator 14 and then sent to the MODEM15. The transmission from the MODEM15 to the MODEM10 is performed through an optical transmitter 11', optical fiber 12', optical receiver 13', and attenuator 14'. This constitution eliminates interference even if the input and output part of the MODEM and the input part of the transmitter are connected directly to the output part of the receiver and enables half-duplex two-way coupling.
