Title: Storage device for extension
Inventor: KIHARA TOSHIYUKI
IPC: G06F12/06
Filed: 1989-07-25
Abstract: PURPOSE:To minimize the operation of a user, to reduce the malfunction, to share an extended memory board, and to reduce the cost by switching a board select signal in each extended memory board at the time of extension of many stages of extended memory boards. CONSTITUTION:A discriminating means 15 discriminates the place of an extended memory board and sends the result to a selector 14. The selector 14 determines the operation by the signal from the discriminating means 15 and a board select signal 18 from a main body board, and one board select signal is sent to a memory as a chip select signal 21. Thus, the extended memory board can transmit and receive data to and from a central processing means by discriminating an extended memory board state signal 20. An information transmitting means 16 in the n-th extended memory board takes in the extended memory state signal 20 outputted from the (n-1)th extended memory board and sends an extended memory state signal 19 to the (n+1)th extended memory board. Thus, erroneous connection is prevented, and the main body board including a central processing unit is miniaturized.

Filed: 1992-06-26
Abstract: PURPOSE:To sufficiently reflect difference of toner consumption quantity due to difference of characteristics of images so as to accurately supply toner by weighing image data values by means of appropriate factors corresponding to the characteristics of an image data group. CONSTITUTION:An image data is converted into a binary system and input to a characteristic extraction circuit 34, and characteristics such as sort or space frequency of the image are extracted. A developer consumption quantity in response to the developer consumption characteristic decided from the image characteristic and the mean image concentration from a mean concentration computing circuit 32 is judged by a judging circuit 35. Namely, the curve of developer consumption characteristic is selected from the image sort in the judging territory, and one point (consumed developer quantity judged value) on the curve corresponding to the value of space frequency of the image in the judging territory is decided. This operation is repeated for full territory of the image, and the supply quantity of developer can be estimated by adding the result by a section for supply timing of developer, e.g. by one image.

Title: Optical fiber cable
Inventor: HANAI MASAHIRO
IPC: G02B6/44
Filed: 1985-09-04
Abstract: PURPOSE:To obtain an optical fiber calbe having high reliability by coating an optical fiber with a ferromagnetic body so as to prevent an error in signal due to a large electric current from thunder or the like. CONSTITUTION:A polymer layer 3 on the outside of an optical fiber is coated with ferrite 8 as a ferromagnetic body so that the direction of easy magnetization coincides with the longitudinal direction of the optical fiber in which light is transmitted. When a magnetic field from thunder or the like is applied to the resulting optical fiber cable in the longitudinal direction of the cable, the magnetic field does not pass through the core 1 of the optical fiber but passes through the ferrite 8 because the ferrite 8 is a superior ferromagnetic body. No magnetic field is applied to the core 1 which transmits light and no Faraday effect is produced, so an error in signal transmitted by light is prevented.

Title: Search method for disk player
Inventor: KIMURA TOSHIYUKI
IPC: G11B21/08
Filed: 1990-07-24
Abstract: PURPOSE:To shorten the search time by performing high-speed reproducing till return to a designated address position from a jump back position and switching the reproducing speed to the normal speed at the time of arrival at the designated address position. CONSTITUTION:For the purpose of preventing drop-out of the head part of designated music at the time of starting reproducing, an optical pickup 1 is jumped back inward by a prescribed number of tracks. A high-speed reproducing command is sent from a system controller 12 to a spindle servo circuit 6 to start high-speed reproducing from the jump back track position. When high-speed reproducing is advanced to arrive at a prescribed position before the start of designated music, namely, a position of the number of tracks before the number of tracks is calculated in consideration of the inertia required for return of a spindle motor 6 from high-speed reproducing to normal reproducing, a command for switching from high-speed reproducing to normal reproducing is given to a spindle servo circuit 6 from the system controller 12 to return the speed of the spindle motor 5 rotated at a high speed to the normal reproducing speed. Thus, the search time is shortened.
