Title: Detector for turning speed of internal combustion engine
Inventor: HATA YOSHITAKA
IPC: G01P3/42
Filed: 1981-04-02
Abstract: PURPOSE:To improve safety in detecting the turning speed of an internal combustion engine, by using turning angle detectors which detect different turning angles, finding a speed during a fault on the basis of a normal signal, and then using another rotation detecting means when all detectors are faulty. CONSTITUTION:Sensor 2 detects projections 1a provided at 120-degree intervlas on a disk 1 which rotates synchronizing with an engine, and sensors 3 and 4 detect teeth 1b arranged at 2-degree intervals alternately. Therefore, since the outputs of  he sensors 3 and 4 are ANDed to obtain a signal of every degree, a fault discriminating circuit 5 counts the pulses from the sensors 3 and 4 and if the 120-degree signal of the sensor 2 is not generated when its counts up to 60, the sensor 2 is judged to be normal, thereby controlling the engine by a control circuit 6. If even one of them is normal, its signal is used to find the signal of a faulty sensor. When all of them are faulty, a wheel speed signal 7 and a variable speed gear signal 8 are used to obtain information.

Title: Electron-beam exposure apparatus
Inventor: IGAKI SEIGO
IPC: H01J37/302
Filed: 1979-04-21
Abstract: PURPOSE:To alleviate the load of a host computer, in an electron beam exposure apparatus of a 2 step digital-to-analog conversion system, by dividing the data into subfields when one side of a rectangular datum is longer than the scanning limit of a low-resolution digital-to-analog converter. CONSTITUTION:A pattern generator 6 receives the data from a host computer and sends a signal which determines the X-Y position of an electron beam to a digital- to-analog converter (DAC) 7, which has a high-resolution DAC 7-A that determines the point of scanning start and a low-resolution DAC 7-B that performs scanning. When the exposure-processing-area specifying data are sent from the host computer, the generator 6 judges whether the exposure-processing area exceeds the scanning limit of the DAC 7-B or not. If it does, the exposure-processing area is divided into a plurality of subfields. Since the dividing process is not performed in the host computer, the amount of data is reduced and the load of the host computer is alleviated.

Abstract: PURPOSE:To make it possible to determine the polygonal point or inclination of a polygonal line function by a simple circuit constitution by providing this polygonal line function generating circuit with switches for switching the gain of an operational amplifier and logical elements for controlling the switches in accordance with input voltage. CONSTITUTION:Resistors Rf1 to Rf3 are connected to an operational amplifier 1A through switches SW11 to SW13, SW21 to SW23 and the ON/OFF of respective switches is controlled by an EOR gate 3 and a NOR gate 4 in accordance with an input voltage level. For instance when Vth is set up as the threshold voltage of an IC including the switch 2, the EOR gate 3 and the NOR gate 4 and input voltage Vi is <(R1+R2).Vth/R2, voltage levels of points A and B is 'L'. Thereby the output C of the EOR gate 3 is turned to 'L', the output D of the NOR gate 4 is turned to an 'H' level and only the contacts SW13, SW23 are turned on. Consequently the gain of the amplifier 1A is determined by the resistor Rf3 and the inclination of a polygon line is expressed by Rf3/Ri1.

Abstract: PURPOSE:To improve gradation reproducibility with inexpensive, small-sized constitution and to realize titled head of a high-speed full-color type by mounting a photosensor array, signal pulse width converting means, driving means, and multiprinting means which impose direct dot gradation modulation with pulse width on the same substrate. CONSTITUTION:A signal 32 generated by a photosensor 20 is compared by a comparator 21 with the output 31 of a generation part 13 for a comparison signal and the comparator 21 sends an output 34 so that the output 33 of a flip- flop 22 set previously with a set signal 30 is reset. Therefore, pulse width is modulated according to the level of the output 32 of the photosensor 20. The multiprinting means 24 is driven by a driver 23. The signal ouput of the photosensor 20 is in direct proportion to a covering rate as long as saturation density is fixed, so output gamma characteristics to image density are obtained. A printer, on the other hand, is capable of modulating image density and has gamma characteristics as shown in graph, so a gamma correction curve is determined in total in consideration of the both. Further, the comparison signal output 31 is set on the basis of the correction curve and supplied to realize gamma corrections at a time.
