Title: Test paper supply device
Inventor: TAKEDA GORO
IPC: G01N35/04
Filed: 1995-02-02
Abstract: PURPOSE: To smoothly and automatically supply a test paper and to improve operability by installing a leaf spring for preventing fall on the carrier stage of a transfer device. CONSTITUTION: When a shutter part 9 goes down to a solenoid 10, a test paper 3 is retained at the position until it drops onto a carrier stage 15 and is guided on the wall surface of a support stand groove part 13, the stage 15 moves left and right, and a stage groove part 12 reaches directly below the groove part 13. The paper 3 entering the groove part 12 is carried by the stage 15 and is turned upside down at the position of a test paper inverting mechanism 11 and is taken out. A leaf spring 14 installed for preventing fall is fixed onto the stage 15 by screws and is installed so that it covers a shutter part 9 and then the paper 3 is horizontally maintained on the spring 14 even if the shutter part 9 goes down.  The spring 14 is crushed along with the travel of the stage 15 and the paper 3 slides down horizontally along the inclination on the spring 14, thus preventing the possibility of fall.

Title: Detecting method for effective end position of metallic pipe
Inventor: SEKII TSUGIO
IPC: G01V3/10
Filed: 1983-02-01
Abstract: PURPOSE:To improve accuracy in detecting the recessed position at end by a method wherein a pair of eddy current type sensors are oppositely arranged around a metallic pipe and outputs of both sensors are added after linearizing output voltage characteristics of the sensors. CONSTITUTION:Outputs of analog waveform shaping circuits 3, 3 are applied to linearizers 4, 4, to linearize output voltages due to gap changes, and outputs of the linearizers are applied to an adder 5 to cancel out eccentric components. The output waveform from the adder 5 is as shown in the figure such that signal voltage corresponding to the recessed position at end is clearly detected. An output of the adder 5 is amplified by an amplifier 6 and then applied to a comparator 7, so that a signal is issued when the input voltage exceeds a given level. By so doing, it becomes possible to surely detect the effective end positions at both ends of a steel pipe 10.

Title: Estimating method for thickness of minimum healthy part of corrosing part of pipe wall
Inventor: INOUE SHIZUO
IPC: G01B15/02
Filed: 1989-01-25
Abstract: PURPOSE:To replace a pipe before a through-hole is generated by measuring the thickness of a pipe wall part having a corrosing part as average thickness of a pipe wall in a prescribed measuring range containing this corrosing part. CONSTITUTION:A cross sectional shape of a pipe wall having a corrosing part is assumed as a recessed shape caused by a parabola consisting of only a secondary term and a '0'-order term. By specifying a secondary coefficient of this parabola as a known one by a material of a duct line, a '0'-order coefficient of the parabola, that is, thickness of the minimum healthy part of the corrosing part of the pipe wall is derived from pipe thickness data of the pipe wall measured by a first and a second sensors, respectively, or pipe thickness data of the pipe wall measured by one set of sensor, and prescribed pipe thickness data of a normal pipe wall being free from a pitting corrosion.

Title: Measurement of engine revolutions
Inventor: YAGI KIYOSHI
IPC: F02D45/00
Filed: 1985-01-30
Abstract: PURPOSE:To control the engine efficiently at the startup thereof, by adding the full count value to the current value of a timer when the counter reaches the overflow value in the measuring of signals generated synchronizing the rotation of the engine with a timer. CONSTITUTION:To determine whether the timer measuring the interval between signals generated synchronizing the rotation of the engine, overflows or not, another timer which covers a long time of the minimum digit and a longer time in the full counting is used to measure the interval of the same signal. When the overflowing is found, the full count value is added to the current value in the reading. This enables exact measurement of the revolutions of the engine to the low rotation range at which the overflowing takes place thereby assuring accurate control of the engine at a lower rotation range, particularly at the startup thereof.

Simultaneously, a mark M of an alarm memory indication part 9a becomes an switching-off state. When the switch KS is operated again, an alarm time monitor specification terminal M2 of the circuit 6 becomes to 'H' level to select second alarm time stored in the circuit 6.

Title: Detection system for peeling of plywood
Inventor: INOUE HIRONOBU
IPC: G01N19/04
Filed: 1979-02-15
Abstract: PURPOSE: To inhibit peeling detection of a layer close to a rear surface by detecting the peeling of a layer close to a top surface by a simple constitution by applying vibration pressure to a plywood through a pressure sensing element and contact body and then by detecting pressure, generated through reaction, by the pressure sensing element.  
     CONSTITUTION: Between vibrator 1 excited by coil 2 and contact body 6 touching the surface of plywood 7, pressure sensing element 4 is supported and vibrations of vibrator 1 are applied to plywood 7 by way of element 4 and contact body 6. When plywood 7 has a peeling, vibrations are absorbed and as the peeling is closer to the surface of plywood 7, reactive pressure of vibrations is smaller; and the peeling of a layer close to the surface of plywood 7 is detected through element 4 and level detector 8 and that of a layer close to the rear is not detected. Therefore, only a harmful peeling is detected through simple constitution and a harmless peeling is prevented from being detected.

Title: Signal generating device, ranging device, and optical equipment
Inventor: SUZUKI SATOSHI
IPC: G01B11/00
Filed: 1998-01-29
Abstract: PROBLEM TO BE SOLVED: To form a signal related to distance with good balance by differing the forms of projecting pattern of light emitting parts of a plurality of light projecting elements. SOLUTION: A plural of light projecting elements are formed with different projecting patterns of light emitting part. For example, the light emitting part of the projecting element is formed so that the central ranging point consists of three bars, the ranging point next to the center used when the focal distance of a photographing lens is long consists of two bars, and the outermost ranging point used when the focal distance of the photographing lens is short consists of one bar. The drive current of an LED is set to be large in the center and small in the sides so that the emission luminance is substantially the same in each ranging point.  In the output image of the received image photoelectrically converted on the sensor plane of the central ranging point, the difference with the output value of the adjacent picture element is increased in six positions, and the ranging performance is enhanced. Thus, since the forms of projecting pattern of a plurality of light projecting elements are not equal to each other but differed, the performance balance can be improved without increasing the chip size.
