Title: Waveform shaping circuit
Inventor: TATSUTOMI YOSHIKI
IPC: H04L25/03
Filed: 1994-06-13
Abstract: PURPOSE:To shape the waveform so as to form the edge of an input binary signal in a sine-wave shape without using any linear circuit by connecting one end of each of plural resistors, the other ends of which are connected with the outputs of plural serially connected buffer circuits, with a common reference resistance. CONSTITUTION:Each output of buffer circuits B1 to B9 successively delaying binary input signals Vin of an H/L level to be transmission data by prescribed delay time and outputting the signals is connected with each one end of resistors R1 to R9. Each other end of each of these resistors is commonly connected with the + inputs of a reference resistance R0 and buffer circuit 20, the resistance value of each resistor R1 to R9 is set to be larger in initial step R1 and final step R9 sides and is set to be smaller on a middle step R5 side. As a result, an output signal Vout that a waveform shaping is performed for the signal Vin in a sine-wave shape can be generated and radiation noise generated from communication lines L1 and L2 can be suppressed at the time of a data transmission. Thus, a waveform shaping circuit 10 where linear circuits such as an exponential conversion circuit and an integration circuit, etc., are not used can be compactly and inexpensively constituted.

Title: Center position measuring instrument
Inventor: HASHIMOTO HIROSHI
IPC: G01B11/00
Filed: 1986-06-05
Abstract: PURPOSE:To improve measurement accuracy by irradiating a body to be measured which is arranged between a couple of head parts with a parallel light beam and measuring the center position of the body to be measured based on the movement position of a heat main body when the quantities of photodetection of a couple of photoelectric transducers coincide with each other. CONSTITUTION:The parallel light beam L from a parallel light beam emission part 4 passes through a slit-shaped light transmission part 13 and further passes both breadthwise outsides of the object body (a) to strike on a light reception part 15. The light reception part 15 has the couple of photoelectric transducers 16 and 16 breadthwise and output individually detection currents corresponding to the quantities of reception of the light beam L. The output currents are inputted to a processing control part 17 through a signal output part 18 and a processing part 19. If the head main body 1 shifts from the object body (a), there is a difference generated between the quantities of light reception, i.e. detection currents of the transducers 16 and 16 and the control part 20 drives a driving part 22. The main body 1 moves breadthwise through a ball screw 24 and stops when the detection currents become equal to each other, and a detection part 25 detects the coordinates of the center position of the object body (a). Consequently, a measurement is automatically and easily taken.

Filed: 1988-05-31
Abstract: PURPOSE:To photoelectrically measure the level of a surface to be measured or that of an apparatus by providing an air bubble pipe, a light emitting element and a photodetector. CONSTITUTION:The light from a light emitting element 7 is reflected by an air bubble 4 to be incident on the first photodetector 11 and, when an apparatus to be measured in inclined, the air bubble of an air bubble pipe 1 is moved. For example, when the air bubble 4 is moved to the second photodetector 12 and detected by said photodetector 12, the output thereof is inputted to the first latch circuit 15 as a set signal through an amplifier 17. When the set signal is inputted to the circuit 15, the circuit 15 outputs an H-signal to hold this output state until a reset signal is inputted and a motor reversibly driving circuit 19 is operated, for example, to rotate a motor 20 forwardly and the apparatus to be measured is returned to a horizontal state through a level control mechanism 21. When the apparatus to be measured is returned to a horizontal state, the photodetector 11 detects the air bubble 4 and, therefore, the reset signal is inputted to the circuit 15 to stop the rotation of the motor 20.
