Title: Optical-fiber gyro and its detection-signal correction method
Inventor: NODA JUNICHI
IPC: G01C19/72
Filed: 1993-03-11
Abstract: PURPOSE:To reduce the capacity of a memory which stores correction data by quickly correcting the characteristic deviation of an optical-fiber gyro which is mounted on a navigation system or a vehicle control system. CONSTITUTION:An optical-fiber gyro is composed of an optical system 1 constituting a Sagnac interferometer which uses an optical fiber as a constituent element and of an operation means 2 which computes a rotation-angle velocity on the basis of the intensity of interference light by the optical system 1. In the optical-fiber gyro, correction data for each of a plurality of kinds of representative deviation characteristics which the optical-fiber gyro can take is stored in common in a memory. The representative deviation characteristic to which self-deviation characteristic is closest out of the plurality of kinds of representative 4eviatiom characteristics is investigated in advance, it is selected by a selection means 15, and a rotationangle velocity which is operated by the operation means 2 is corrected by correction data for the selected representative deviation characteristic.

Title: Mold for resin sealing
Inventor: SANO YOSHIAKI
IPC: B29C45/73
Filed: 1986-03-07
Abstract: PURPOSE:To uniformize the temperature distribution of the whole mold and consequently prevent molded resins from generating strain by a structure wherein a high thermally conductive member such as a metal plate, a metal rod or the like, the thermal conductivity of which is better than that of a cavity clock, is provided at least on the surface of a mold consisting of a top force and a bottom force. CONSTITUTION:A heat transfer member 24 consisting of a sheet of copper, the thermal conductivity of which is better than that of iron, is provided on the top surface of a bottom force 21 of a mold excluding the portion contacting with an opening 23, through which resin is poured under pressure. In addition, iron cavity blocks are connected onto the top surface of the bottom force. By the structure as mentioned above, both the heat of molten resin and the heat generated by heaters 25 imbedded in the bottom force 21 are transferred more rapidly than before the the wide region of the bottom force 21 of the mold. This removes the phenomena that the temperature at the peripheral part of the bottom force 21 of the mold is lower than that at its central part and the temperature distributions of the cavity blocks connected to the mold become uniform.

Inventor: HOTTA TERUO
IPC: H04N5/05
Filed: 1988-03-04
Abstract: PURPOSE:To automatically correct the waver or the bend, etc., of a picture due to jitter by inputting a horizontal synchronizing signal from a synchronizing separator circuit as a preset pulse, generating the signal of the same frequency as the horizontal synchronizing signal and performing the logical operation of it with the horizontal synchronizing signal complimentarily. CONSTITUTION:A first counter 11 and a second counter 12 input a clock signal from a VCO 7 as considering the horizontal synchronizing signal to be the preset pulse, and count the clock signals of prescribed numbers different from each other. Thus, a flip-flop circuit 22 generates a rectangular wave signal (d) of the frequency nearly the same as the horizontal synchronizing signal. The counters 13 and 14 count down output signals from respectively a NOR gate circuit 19 and an AND gate circuit 20 as considering the horizontal synchronizing signal to be the preset pulse, and when the values of the respective counters become '0', they output borrow pulses to the NAND gate circuits 17 and 18 respectively. Thus, the waver or the bend, etc., of the picture is automatically corrected by switching an LPF 5 and the LPF 6 to the one of an adequate characteristic.

Title: Forecasting control device
Inventor: TAKAHASHI ISAO
IPC: G05F1/10
Filed: 1986-03-10
Abstract: PURPOSE:To execute forecasting control by estimating a periodical component from a past command value, advancing the component by a required period to find out a forecasted value, detecting a non-periodical component from a difference between the estimated value and a current value, making the non-periodical component approximate to a quadratic equation to find out a forecasted value preceding by a prescribed time, and adding the current value to the forecasted value. CONSTITUTION:A function part 20 calculates the estimated value - r(t) of the periodical component on the basis of a command value i*c and a subtractor 16 subtracts Td i* from the estimated value - r(t) to find out epsilon and detect the non-periodical component n(t). A function part 30 advances the value - r by Td and outputs r** and a function part 40 makes epsilonn+1 approximate to a quadratic equation on the basis of past points epsilonn-1, epsilonn-2, epsilonn delayed by Td each from a current point tn through Td delay elements 41, 42, a subtractor 43, a coefficient multiplier 44, and an adder 45 and outputs n**=epsilonn+1=epsilonn-2+3(epsilonn+epsilonn-1-) and the output is added to r** by an adder 17 to supply a forecasted value i**c at a feature point. Since forecasting control is executed by supplying the i** advanced by the Td though the output current ic of the device is delayed from the command value i* by the Td, the follow-up property of the device to the command value is excellent.

Abstract: PURPOSE:To make it unnecessary to condense the reflection light flux to facilitate the assembly and the adjustment of an optical system, by diffusing and converging the reflection light flux from a disc to obtain a focus error signal. CONSTITUTION:The diffused light from a semiconductor laser light source 1 is converged onto a disc 7 by a condenser lens 5, and three reflection light fluxes are reflected by a polarizing prism 4, and a transmission type interference filter 8 is arranged in the path for the center light flux. The filter 8 is so inclined to the optical axis that the intensity of the light discharged from the filter has a middle value between a maximum value and a minimum value. A division line l between photodetectors 9a and 9b is let to be orthogonal to the optical axis as well as a plane, which includes the optical axis and the normal of the filter 8 in the optical axis position, out of planes orthogonal to the plane of the filter 8. The difference signal between outputs of detectors 9a and 9b is used as a focus error, and the lens 5 is so controlled that this focus error becomes zero, and thus, a minimum light spot is generated on the signal face of the disc 7.
