Title: Chinese character input and output device
Inventor: MORITA SHIGEYUKI
IPC: G06F3/00
Filed: 1980-06-05
Abstract: PURPOSE:To realize a practically sufficient number of kinds of Kanji (Chinese character) conversion processing, by displaying desired Kanji patterns corresponding to Kana (Japanese syllabary) character information with specific effects added. CONSTITUTION:Kana characters from a keyboard 1 are stored through an input/output port 3 in a RAM4 by an arithmetic control part 2. After that, when a Kana character is designated by the operation of a special key, the control part 2 detects it by a program and refers to a Kanji table to read out Kanji pattern information from a floppy disc 6. This information is code-converted and is stored in a video signal memory 9. Next, if information read out from the memory 9 corresponds to Kanji pattern information, a Kanji buffer memory 8 becomes active, and Kanji pattern information corresponding to Kana character information is read out and is displayed in a specific position on the display device screen.

Title: Optical recording medium
Inventor: NAKAKUKI HIDEO
IPC: G11B7/24067
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To lessen the deterioration at the beginning and terminal of a sector in the repetition of rewriting and to obtain a good jitter characteristic by having at least a low-reflective index layer, a first dielectric layer, a recording layer, a second dielectric layer and a reflection layer in this order on a substrate and determining the refractive index of the low-reflective index layer so as to satisfy a specific relation with the reflective index of the substrate. SOLUTION: The low-refractive index layer is required to be selected from materials of which the refractive indexes (n) are 0.7ns <=n<=1.3ns with respect to the ns of the substrate. As a result, the free designing of the thickness of the low-reflective index layer is made possible with substantially no change of the optical characteristics, such as reflectivity. The hardness, Young's modulus, thermal conductivity and heat capacity of the low-refractive index layer which are higher than those of the first dielectric layer are preferable as well. Consequently, the low refractive index layer has a high strength and the low- refractive index layer has high strength and the fluctuation in the recording film by the expansion and shrinkage accompanying the rewriting of recording may be suppressed.

Title: Device and method for reproducing information
Inventor: KAWAKAMI SATOSHI
IPC: H04N21/218
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To continuously reproduce the respective clips of information material having plural clips without using any dedicated special encoder by raising a write end flag at the time point when the cluster of certain clips is completely written from a recording medium into an information material saving means. SOLUTION: When there are invalid data DD in a terminal cluster CT4 of preceding clip CP1 in the case of reproducing the clip CP1 preceding to a certain clip CP2 in the information material from a DMA buffer, in the access sequence of DMA buffer, a write end flag WFF is raised by the group of external controller or CPU at an end flag generating means at the time point when the cluster CT1 of clip CP2 is completely written from the hard disk drive of recording medium into the DMA buffer. Even when there are invalid data in the terminal cluster of preceding clip, the terminal cluster having the invalid data is continuously reproduced by an information material reproducing means until the write end flag WFF is raised.

Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a deviation in transfer by freely turnably supporting an upper pretransfer guide with a pair of floating pins and regulating/ keeping the upper pretransfer guide to/at a fixed position with an elastic member and a butting position regulating member. SOLUTION: The upper pretransfer guide 501 is freely turnably supported by a pair of the floating pins 508, in such a manner that the center of turning is provided in the vicinity of an image carrier 1 and regulated to the fixed position by an energizing spring 503 having a spring pressure (light pressure) of irreducible minimum strength required for regulating/keeping the upper pretransfer guide 501 to/at a normal position and a position regulating floating pin 507.  Therefore, even if the bottom end of a transfer sheet such as a cardboard passes through resist rollers 505 and 506, the upper pretransfer guide 501 is pushed up by the stiffness of the bottom end of the transfer sheet, to reduce the frictional resistance between the transfer sheet S and the upper pretransfer guide 501, so that the transfer sheet S can be carried by electrostatic attracting force to the image carrier 1, without any problems. Further, even if the transfer sheet such as a thin paper that is not sufficiently stiff is carried, the transfer sheet can be guided/carried without any problems, and the deviation in the transfer never occurs.

Title: Centrifugal pump
Inventor: NAKAWA YASUMASA
IPC: F04D29/46
Filed: 1981-05-22
Abstract: PURPOSE:To raise the pump efficiency, by changing the maximum sectional area at the end of the volute of a volute casing of a centrifugal pump by shifting a tongue of the volute casing, and thereby improving matching between an  impeller and the casing. CONSTITUTION:A movable tongue 1 is provided in a casing 2 in the manner that it can be slid in a direction x by turning a nut 3. When the top of the tongue 1 is located at a position a shown in the drawing, the maximum area Smax at the end of the volute of the casing 2 is maximum. On the other hand, when the top of the tongue 1 is located at a position b shown in the drawing, the maximum area Smax becomes minimum. Thus, according to the present invention, the value of Smax can be changed freely. Therefore, the pump efficiency can be raised by improving matching between the casing 2 and an impeller 4 by selecting the value of Smax such that the pump can be operated in optimal conditions.
