Title: Method for detecting focus control signal of optical information reader
Inventor: TANAKA YOSHIHARU
IPC: G11B7/09
Filed: 1982-06-14
Abstract: PURPOSE:To prevent the effect of a change in a distributing amount of light or the like in a light beam due to a cause arisen later, by catching an almost rectangular wave in form in an information reproducing signal, and detecting the distortion to make it a focus control signal of an irradiating radius of the light beam to an information medium. CONSTITUTION:If a relation of position between a photoelectric converting element 13 and an irradiated spot 14 at the matched focus is shifted because of a succeeding cause after an objective value is set, the difference of the amount of received light on a photo detecting plane to the same shift amount of focus is changed also, then the difference with the objective value is changed also and a suitable correcting signal is not obtained. In this case, the difference of the detected output is produced with the relation of position with a condenser lens 7 of an information medium 8 and the difference does not depend on the change in a distributing amount of light of a beam spot 9 on the information medium 8, and the shift in the optical axis of the light beam 2. Thus, the accurate focus control signal is received by changing suitably the objective value based on the change in the amount of difference of the output.

Title: Device and method for preventing overturn of crane
Inventor: SASAKI KIHACHI
IPC: B66C23/88
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To make an operator perform the overturn avoiding operation with enough time by increasing the time latitude from the time when an alarm for informing danger of turnover is output to the time of the actual overturn. SOLUTION: Whether a crane is to be overturned or not is judged by taking the rotational center of a joint part 14 of an outrigger 10 as the overturn fulcrum H. When it is judged that the crane is to be overturned, an alarm signal is output. Since a fixing command signal for fixing the turning movement of the joint part 14 is output when the alarm signal is output or until an alarm signal is to be output, the operation of the joint part 14 of the outrigger 10 can not be performed at the time when the alarm signal is output.

Title: Intermediate frequency circuit
Inventor: YAMAMOTO HIDEKI
IPC: H04B1/26
Filed: 1990-04-17
Abstract: PURPOSE:To prevent an uncomfortable tone from being generated by noise even when an antenna input is lowered by a weak electric field by providing a control circuit to control a time constant under control related to the output of a comparator circuit, and changing the frequency characteristic of a sound signal in relation to the operation of this control circuit. CONSTITUTION:When the input of an intermediate frequency signal is made lower than a prescribed value A1, an AGC voltage VAGC is increased corresponding to the reduction of this intermediate frequency signal input. Therefore, when the intermediate frequency signal input reaches a value A2, the AGC voltage VAGC is made equal to a reference voltage VA applied to the base of a transistor Tr2. In this case, a transistor Tr4 is tured on, a capacitor C2 is parallelly connected to a capacitor C1, a time constant Tc is enlarged and a de-emphasis characteristic is changed. Thus, when the noise is apparently enlarged by the reduction of the intermediate frequency input and the uncomfortable tones are reproduced by the noise, the high frequency component of the noise is attenuated by lowering the frequency of starting the attenuation of a sound signal Ss.

Title: Variable light branching/coupling device
Inventor: KURATA NOBORU
IPC: G02B6/28
Filed: 1989-04-21
Abstract: PURPOSE:To optionally vary the branching ratio of light by melting and splicing one part of the outside circumferential surfaces of two or more optical fibers each other, mechanically drawing the spliced part in the optical axis direction of the optical fiber and pressurizing and shaping around the center of the spliced part in a vertical direction to the optical axis. CONSTITUTION:After one part of the outside circumferential surfaces of the optical fibers 11 and 12 consisting of an elastic member are heated, melted and spliced each other, the drawn melted and spliced part is gradually thinned and drawn until the outside diameter of the central part of the melted and spliced part 13 becomes almost the thickness of one optical fiber. At this time, the thickness of the melted and spliced part 13 is controlled by varying the drawing length of the melted and spliced part 13 and simultaneously pressurizing it from the vertical direction to the optical axis. Thus, the quantity of the light coming through one optical fiber 11 at the melted and spliced part 13 can be varied. As the result, the branching ratio of the light is optionally varied.

Title: Fault detecting circuit for pressure sensor
Inventor: OKANO HIDEO
IPC: G01L1/22
Filed: 1988-04-26
Abstract: PURPOSE:To easily and securely judge a fault due to the breaking of a wire by comparing the terminal voltage across a detection resistance with the terminal voltage at the time of the breaking of the wire which is a reference value. CONSTITUTION:The pressure sensor applies a constant voltage Vcc to the bridge formed by connecting the resistance Rs of a pressure sensing element and three reference resistances R1-R3 in series and inputs respective potentials between both connection points adjacent to the connection points to which the constant voltage is applied, thereby generating outputs corresponding to the potentials. The detection resistance RH is connected between the connection point facing the connection points to which the constant voltage Vcc is applied and the earth. Then, the terminal voltage VH across the detection resistance RH varies according to whether or not the wire is broken. Therefore, if the wire is broken, the terminal voltage VH2 is used as the reference value and compared with the terminal voltage VH by comparators CP1-CP3, thereby deciding whether or not a fault is caused by the breaking of the wire from the outputs of the comparators CP1-CP3.

IPC: B22D11/16
Filed: 1991-04-05
Abstract: PURPOSE:To measure the molten metal level of the inside of a mold by containing a level distribution in the width direction of the mold in the course of operation of a continuous casting equipment, and also, to measure the molten steel level which ascends in the inside of the mold with high accuracy extending over almost the whole area in the vertical direction of the mold at the time of starting the operation of the continuous casting equipment. CONSTITUTION:Plural pairs of transmitting coils 10 and receiving coils 11 separated vertically by suitable length by inserting and holding a correct level L of molten steel 2 are placed in the width direction of a mold 1. The transmitting coils 10 of each pair are excited by an exciting current of a low frequency from an oscillator 12, and an induced current induced in the receiving coil 11 in this case is given to a phase difference detector 14 through an amplifier 13. A phase difference of the exciting current and the induced current being outputs of the phase difference detector 14 corresponds to whether a level of the molten steel 2 between the transmitting coil 10 and the receiving coil 11 is high or low, and by this phase difference, an arithmetic part 15 calculates the level of the molten steel 2. Instead of the phase difference, an intensity difference of the exciting current and the induced current can also be used. At the time of starting the operation, plural coils are placed in the vertical direction of the mold 1, these are allowed to function as the transmitting coil or the receiving coil in order from the lower part, and the level measurement extending over a wide range is executed.
