Title: Manufacture of optical fiber preform rod
Inventor: IWAMOTO TOSHIO
IPC: G02B6/00
Filed: 1983-06-20
Abstract: PURPOSE:To facilitate the control of the refractive index distribution in the soot for an optical fiber preform rod, by depositing a soot composed mainly of quartz to the outer circumference of a core glass composed mainly of quartz, and vitrifying the soot in an gaseous atmosphere containing a dopant. CONSTITUTION:The soot 2 composed mainly of quartz (e.g. deposition of SiO2 powder obtained by the oxidation or hydrolysis reaction, etc. of the halide, hydroxide, or organic compound of Si) is deposited to the outer circumference of the core glass 1 composed mainly of quartz, and the obtained preform rod is inserted into a vitrification furnace 4, and vitrified in a gaseous atmosphere containing a dopant (e.g. an atmosphere of an F-containing gas such as CF4, etc.) to obtain an optical fiber preform rod having the glass layer 5. Since the control of the refractive index of the soot formed to the circumference of the core glass is carried out not at the soot-forming stage but at the vitrification stage, the control in the soot-formation stage can be simplified, and the influence of the dissipated dopant in the vitrification stage can be made negligible.

Abstract: PROBLEM TO BE SOLVED: To easily set proper communication speed by considering noise resistance corresponding to the traveling state of an automobile. SOLUTION: At the time of starting a system and at the time of accelerating and decelerating an automobile a transmission speed confirming command is transmitted from a master device to a slave device to detect a responding speed from the slave device to grasp network congestion, and when the responding speed is low, it is instructed to reduce the communication speed of each slave device. In addition, where an error rate larger than a specific rate is detected as the result of detecting the error rate of communication data and communication congestion is generated, the communication speed is forcedly reduced. In other cases, it is instructed to execute communication by the upper limit value of the communication speed corresponding to the communication capability of each slave device.

Title: Automatic exposure device
Inventor: HONDA MITSUNOBU
IPC: G03G15/00
Filed: 1989-04-28
Abstract: PURPOSE:To always measure only light made incident at a fixed angle, to control a light quantity according to an original density by detecting the original density of the part to be copied by integrally moving a density detecting element and a regulation member which regulates light made incident on the density detecting element. CONSTITUTION:A density sensor 5 is shielded circumferential light by a case 10 and only the light made incident at the fixed angle theta is measured. When the case 10 is at a reference position, the length of an optical path between an original 23 and the sensor 5 is l. For example, when the case 10 is at a position A, the length of the optical path between the original 23 and the sensor 5 is la, and light made incident on the full width of an A5 original, orthogonal to the scanning direction is measured. The larger the incident angle is, the lower the sensitivity of the density sensor is. By integrally moving the density sensor and the regulation member, reflection light from only the area to be copied of the original is always received at the fixed angle, besides reflection light from other part is not received. Therefore, the original density of the area to be copied can be correctly detected without influenced by the density other than the area to be copied.

SOLUTION: A steel strip is formed in an open-type cylindrical shape by an FF-X mill 15 of a forming facility, both edges thereof are welded by a welding facility 10 to form a pipe. The pipe is then straightened in the longitudinal direction by a straightener 13, and cut to the specified length by a cutting machine 14. The FF-X mill forms most of a stock width area directly aiming at the curvature of a product using an excellent edge bend forming system of the forming function in the first break-down forming part of the forming process, and forms a sectional shape easy to obtain the specified curvature distribution through the fin-pass forming in the second forming process.  The break-down forming of the FF-X mill 15 is adaptable to the outside diameter and the wall thickness of the product without changing rolls, and the steel strip width is easy to be adjusted for the control of the circumferential length. A sizer and roll exchange can be dispensed with when the outside diameter of the steel tube is changed.

Title: Knock detector for internal combustion engine
Inventor: MOGI KAZUHISA
IPC: G01M15/04
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To prevent an erroneous judgment that knock exists from being caused by an LC resonance current in an ion current route. SOLUTION: A device sets an LC resonance frequency determined by the inductance L2 on the secondary side 1b of an ignition coil and the stray capacity C2 formed in an ion current route so that it is deviated from a knock frequency so as to detect only a knock frequency component accurately from an ion current output. Also the inductance L2 should be desirably set at an large value to set the LC resonance frequency smaller than the knock frequency in order to increase an ignitability in addition to a knock detectability. In addition, an LC resonance frequency should be desirably set smaller than a low range cut-off frequency of a band pass filter for knock signal extraction which is installed in a process circuit 20 so that the LC resonance frequency component causing noise can be removed more securely.

IPC: G06F12/00
Filed: 1985-05-24
Abstract: PURPOSE:To execute the data transferring by a DMA at a single DMA control circuit by providing the register for extending the memory address and setting the memory space beforehand in which a direct memory access (DMA) is to be executed. CONSTITUTION:When the data transferring is executed by a DMA, a processor 1 sets the address of the segment (for example, segment 6) of the memory to execute the data transferring to a register 3 for extending the register. The initial value to execute the data transferring in a segment 6 is set and started to a DMA control circuit 2. the register 3 sends the segment address set at the segment 6, and the circuit 2 reads a series of the data from the address for which the reading of the segment 6 is designated, by the address set to the internal register. Next, the data are successively transferred and written to the address space continuous from the address for which the writing of the segment 6 is designated. Thus, without providing plural DMA control circuits, the DMA can be transferred by a single DMA control circuit in the optional memory.
