Title: Bent shaft thick barrel roll and pinching device thereof
Inventor: YANO AKITOMO
IPC: B65H27/00
Filed: 1988-03-25
Abstract: PURPOSE:To obtain a roll which prevents the lopsided distortion of a conveying object while having a width maintaining function by bending both sides of a roller shaft in a direction different from the bend plane of its center portion and rotating a roller while expanding/contracting same in the axial direction to form a flat portion on its outer periphery. CONSTITUTION:A tapering roller 50 is rotated around a roller shaft 10 while forming a flat portion 51 in the axial direction on a part of its outer periphery based on the bend of the center portion 12 of the roller shaft, to form a roll 50. As a result, a conveying object can be widely brought into contact with a roller face enabling the conveying object to travel without causing lopsided distortion. On the other hand, by bending both side portions 11 of the bend portion of the roller-shaft center portion 12 in the direction different from the bend plane of the center portion 12, portions bent in the advancing direction of the conveying object can be formed on both sides 11 to apply a force in the direction of spreading the width of the conveying object to the object based on these portions. Thereby, a roll 50 having the function of maintaining the width of the conveying object can be obtained.

Title: Testing method for wetting of building material
Inventor: TSUKAMOTO AKIRA
IPC: G01N27/04
Filed: 1980-05-31
Abstract: PURPOSE:To separately measure the wetting of a building material by dew condensation and the wetting by rainfally by inserting electrodes for the purpose of detecting internal moisture contents as electric resistances into the building material and disposing a heating plate for evaporating moisture by dew condensation. CONSTITUTION:In the case of measuring the moisture contents of a building material 1 occuring in dew condensation, the electric resistance across a pair of electrodes 2, 2 inserted to the inside of the material 1 is detected without applying heat  to a heating plate 3, and the moisture content thereof, that is, the wetting condition of the material 1 is measured. In the case of measuring the moisture contents occuring in rainfall, the plate 3 is heated in order to allow condensed dew to evaporate, thereby removing the moisture by the dew condensation. Thence, the heating of the plate 3 is ceased, and the moisture content by rainfall is meaaured by detecting the electric resistance across the electrodes 2, 2, whereby the wetting state of the material 1 owing to the rainfall is measured.

Title: Ultrasonic beam former
Inventor: KAKIZAWA TAKESHI
IPC: G01N29/26
Filed: 1989-03-24
Abstract: PURPOSE:To improve a frequency characteristic and to enhance an S/N ratio by bypassing an unnecessary delay wire part by providing a delay wire part change-over means for changing over the delay wire part when an aperture becomes large and small by aperture control. CONSTITUTION:An output terminal change-over device X is an analogue multiplexer and selects either one of output terminals I, II, III, O on the basis of a control signal S3 to issue output to a buffer amplifier B. Further, a controller C changes over the output terminal change-over device X in connection with aperture control on the basis of the control signal S3 and allows said change-over device X to select the output terminal I when an aperture is formed by ultrasonic vibrators M, L1, R1 during a receiving period nearest to a transmission pulse P. At this time, when the signal of the ultrasonic vibrator M receives necessary delay with respect to the signal of the ultrasonic vibrators L1, R1 at the delay wire part due to inductances H1, H2 and a variable capacity diode F1, no trouble is generated by the output signal of the output terminal 1. Rather, advantageousness is obtained because no deterioration of a frequency characteristic or no lowering of an S/N ratio is generated.

Abstract: PURPOSE:To ensure the relay by the substitute of the slave station even in case the central station is broken down, by providing the backup function and the program of the central station to the specified slave station. CONSTITUTION:For one sheet of switch on which change-over switches 18-1-a and 21-1-a are put in correspondence to each other, the constant-open contacts of them are connected mutually via connection lines 22-1-a-22-N-a.

IPC: F24H3/08
Filed: 1990-03-26
Abstract: PURPOSE: To improve efficiency of a title apparatus, by reducing deviation of temperature between a heating article and an article to be heated upon heat exchange. CONSTITUTION: A fluid flow performs first heat exchange with a combustion product having higher temperature than that of a fluid flow in the first place, and performs second heat exchange with a heat exchange fluid. The fluid flow further performs third heat exchange with the combustion product, and thereafter the combustion product is used upon the first heat exchange. Thus, upon heat exchange there is reduced a deviation of temperature between a heating article and an article to be heated. As a result, apparatus efficiency is improved.

Title: Scanning type plane magnetism detecting device
Inventor: ARAKI NOBUHIRO
IPC: G11B5/84
Filed: 1988-03-28
Abstract: PURPOSE:To detect magnetism at a high speed, with high density, and also, with high sensitivity even if a magnetic distribution of a magnetic medium is wide by reflecting and converging the magnetism which diverges from each point of the magnetic medium and converting the magnetism to an electric signal by a Josephson element. CONSTITUTION:By a rotation of a rotary mirror 3, magnetism which diverges from each point in the rotating direction of the rotary mirror 3 in a magnetic medium 1 is reflected by a time division, and this reflected magnetism is converged onto a Josephson element 5 by an elliptical mirror 4. The Josephson element 5 converts the converged magnetism to an electric signal by a time division and outputs it. Subsequently, by adding a rotational scan of the rotary mirror 3 and moving the magnetic medium 1 in the direction vertical to the rotational scanning direction of the rotary mirror 3, the magnetism of the magnetic medium 1 can be detected like a raster.

Title: Exhaust gas concentration sensor abnormality detecting device of internal combustion engine
Inventor: SEKI YASUNARI
IPC: G01N27/26
Filed: 1994-03-18
Abstract: PURPOSE:To avoid false detection caused by environmental conditions in starting by holding abnormality judgement when the output value fluctuation amount of an exhaust gas concentration sensor is less than the specific value from the time when an engine is started to the time when it reaches the specific driving state. CONSTITUTION:In a checker circuit, a switch 20 is turned on in a state where output voltage is settled, thereby current to flow into an O2 sensor 16 is increased, and the output voltage is checked by an ECU, thereby deterioration of the O2 sensor 16 is detected. A timer value is set to the specific time when an engine is in a starting mode, and whether the output voltage fluctuation amount of the O2 sensor 16 is less than the preset limit fluctuation value or not is judged. And it is judged that the O2 sensor 16 is normal when the output voltage fluctuation amount is more than the limit fluctuation amount. At this time, the abnormality judgement is held by judging that the O2 sensor 16 is inactive until the specific time passes after starting even when the output fluctuation amount of the O2 sensor is low, and even when an abnormality of the O2 sensor is detected. Therefore, false detection of the abnormality judgement of the O2 sensor 16 can be prevented.

Abstract: PURPOSE:To perform proper grinding by detecting the presence of a flaw on the surface of a raw material plate by an optical flaw detector, detecting the depth size of the detected flaw by a probe type flaw detector, and thus detecting the depth size of the flaw efficiently. CONSTITUTION:The fed raw material plate 1 is moved first oppositely to the optical flaw detector 8, which detects the flaw present on the surface of the raw material plate 1. When the signal from the detecting circuit 10 of the detector 8 is outputted to a controller 16, the rotation of a feed roller 2 is stopped under the command of the detector 8 when the flaw of the raw material plate 1 detected by the detector 8 is moved to the probe type flaw detector 11, thereby stopping the movement of the raw material plate 1. The detection head 12 of the detector 11 is moved and a contactor 14 is put in the flaw of the raw material plate 1 and brought into contact with the bottom surface. The contactor 14 contacts the bottom surface of the flaw and moves according to its depth to cut off the magnetic flux of a detection coil 15, so the depth size of the flaw is found from the cutting extent of the magnetic flux.
