Title: Image forming position adjusting structure of virtual switch
Inventor: OKAMOTO AKITO
IPC: G02B27/02
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To simply and inexpensively form a video on a fixed position regardlessly of kinds of color by forming grooves for adjusting the positions of a lens unit and an image sheet in the optical axial direction on a casing. SOLUTION: Projections opposite to each other are formed on a frame body holding the lens unit of a lens assembly 5. The grooves are formed respectively on the opposite inner wall surfaces of the casing 2 in the optical axial direction at a prescribed pitch. The projection of the frame body of the lens assembly body 5 is engaged into any opposing groove. When the color of a surface light source 3 is changed from red to green, the lens assembly body 5 and a translucent image sheet (inscription plate) 4 are pulled out from the grooves to be inserted into the upper grooves respectively (lens assembly 5' and inscription plate 4'). Thus, the video A by the green surface light source 3 is formed on the position of S of an upper part opening part being the same image forming position as that when the surface light source 3 is red.

Title: Waveform shaping device
Inventor: MAEDA TETSUO
IPC: H03K5/08
Filed: 1985-08-29
Abstract: PURPOSE:To suppress occurrence of an AC offset smaller even in a high frequency band and, at the same time, to easily constitute a waveform shaping device with ICs, by constituting a current switch which converts the output of a comparator into an error voltage after averaging and a time constant circuit to a symmetrical condition by using NPN transistors only. CONSTITUTION:A reference voltage 3 and input signal Vin are inputted to a comparator 4 and the differential output of the comparator 4 is connected with the differential input of a current switch. The output of the switch is connected with a reference voltage VR2 through load resistances 8 and 9. A capacitor 10 is also differentially connected with the output of the current switch and two outputs are connected with the differential input of a voltage-current converter 11. the output current IE of the converter 11 is fed back to the comparator 4. Therefore, an error voltage VE changes toward the negative side and the current IE also becomes negative and apparently lowers the signal Vin in the section where the signal Vin is higher than the reference voltage VR1. The state becomes reverse in the section where the signal Vin is lower than the voltage VR1. Therefore, if a time constant which is determined by the resistance 8 and 9 and capacitor 10 is set longer then the period of the signal Vin, an AC offset can be suppressed by using an ordinary IC-using process even in a high frequency band.

Abstract: PROBLEM TO BE SOLVED: To detect an abnormality generated by water drops by arranging each sensor for measuring a temperature and pressure on the outlet/inlet for a turbine of an operating fluid, measuring each pressure ratio and each temperature difference in the outlet/inlet on the basis of these measured results, and analyzing a condensing condition of water drops in a turbine. SOLUTION: Each temperature sensor 61, 62 and each pressure sensor 71, 72 are arranged on an inlet and an outlet for a turbine, and a temperature and pressure of an operating fluid passing the turbine are respectively measured. On the basis of the measured result, in an abnormality diagnosing device 8, a theoretical temperature fall by adiabatic expansion of the operating fluid is calculated, and an adiabatic efficiency of the turbine is multiplied by the calculated value. Its multiplication value is compared with a temperature difference between the outlet and inlet for the turbine. When the difference is lower than the multiplication value, an abnormality is judged, and an alarm signal is sent. After that, an abnormality in the turbine is alarmed by an abnormality alarm device 9.  An abnormality generated by condensation of water in a casing 5 is automatically detected so as to generate alarm.

The resistance element 13 is constituted by parallelly arranging n-numbers of resistance bodies R1-Rn between a range (d) on an insulating substrate 14 and these resistance bodies are successively connected in series. In this case, the range (d) is made smaller than the interval lambda. When the rotor 1 is rotated, an output signal is issued to a terminal (b) but pulse signals n-times of recording numbers of magnetic signals are obtained by one rotation of the rotor 11 and, if theses signals are counted while specifying a time width, a rotary speed can be measured with high accuracy.

Title: Digital subtraction system
Inventor: KANAMORI KOUJI
IPC: H04N7/18
Filed: 1982-10-30
Abstract: PURPOSE:To obtain a picture having the minimum limit of a false image by detecting a position shift between a mask image and a temp image through processing of picture and having automatic position matching between both images to perform a subtraction. CONSTITUTION:A CPU38 is connected to a frame memory 26 in an access enable way. While the designation for a processing region, the number of movable picture element, etc. are supplied by an input device 40. In this system, the difference of density is obtained between the mask and the temp images for each picture element in terms of some region designated previously, and the picture elements having the difference values larger than a set level are excluded. Then the mask or the temp image is shifted by a picture element along each coordinate axis by noticing the density value of each picture element of a spot train produced among the remaining picture elements. These shifted picture elements are counted, and the difference of the density is obtained with each count between both images. Then the position shift is compensated based on the shift counting done along each coordinate axis to perform subtraction when the density value of each picture element is approximately zero.

Title: Amplifier device
Inventor: MIKAMURA YASUKI
IPC: H03G11/00
Filed: 1989-07-24
Abstract: PURPOSE:To reduce the saturation degree of a transformer impedance type amplifier and to obtain an output signal having no distortion from a large input light current by using a gate means as a by-pass route when the potential difference between the input and output of the amplifier is more than a prescribed value to prevent an output voltage from being dropped. CONSTITUTION:An enhancement type FET Q5 to be a gate means having a gate is connected in parallel with a feedback resistor Rf. The source of the FET Q5 is connected to the output terminal 3 of the amplifier 2 and its drain and gate are connected to the input terminal of the amplifier 2. When an input light current iPD is increased and current flowing into the resistor Rf is increased, the potential difference between the input and output of the amplifier 2 is increased. When the value exceeds a threshold voltage, current starts to flow between the drain and source and the by-pass route is formed. Consequently, the saturation of the amplifier 2 can be suppressed without advancing the drop of the output voltage VOUT to a prescribed value or less.
