Abstract: PURPOSE:To improve the detecting accuracy in a device for detecting the combustion state of an engine from fluctuations of the engine speed by correcting combustion state parameters, etc., containing error factors based on information on the engine speed in a specific operating condition, and information on abnormality in combustion by an air-fuel ratio sensor, etc. CONSTITUTION:In response to the combustion process of an internal combustion engine, the time required to rotating through a specified crank angle is measured by a calculating means 701. Based on the specified time, combustion state parameters are calculated by a calculating means 702. Then, the calculated combustion state parameters are inputted to a correcting means 703. On the other hand, the output of an air-fuel ratio sensor is detected by a detecting means 704 to be A/D converted, and the information on the combustion state detected by a judging means 705 is inputted to the correcting means 703. Then, the correcting means 703 corrects errors of the width of the engine speed measuring range, messes of operating members, etc. Thereafter, a judging means 707 judges the combustion state in response to the corrected combustion state parameters, and at an abnormal time, an informing means 708 informs the abnormality.

Title: Semiconductor storage device
Inventor: YAMAMURA MITSUHIRO
IPC: G11C17/00
Filed: 1993-07-14
Abstract: PURPOSE:To prevent data of non-selection memory cells at the time of a write-in from being damaged by providing circuits setting low levels on data lines at writing-in potentials at the time of writing data. CONSTITUTION:Low level potential setting circuits 1, 2 connected respectively to output lines 4, 5 of write drivers IN1, IN2 and constituted of P channel transistor T13 sets low levels at the time of the write-in on bit lines BL, -BL being data lines and data busses DB, -DB at writing-in potential levels. By such a constitution, in a case that the sides of data lines go to low levels and the sides of latch circuits go to high levels, OFF currents flowing in transfer gates T1, T2 of non-selection memory cells at the time of the write-in are reduced. Thus, data of non-selection memory cells at the time of the write-in are prevented from being damaged and the margin of the power supply voltage of the side of low levels can be maintained large.

Title: Printing magnet tester
Inventor: NISHIDA KAZUSHI
IPC: B41J2/30
Filed: 1990-06-29
Abstract: PURPOSE:To measure an exciting current to a printing magnet in a simple and correct manner by a method wherein an exciting current within a predetermined time from the start of excitation to the end is sampled, and the average value of the appropriate exciting current is outputted as digital data. CONSTITUTION:When an exciting current (i) flows to a printing magnet 13 from a drive power source 11, a voltage proportional to the exciting current (i) is generated between the both terminals of a voltage generator 16. This voltage value is converted to a digital value by an A/D converter 17 to be outputted to a comparator 19. An output value from a slice level generator 18, which is set to a predetermined value, is outputted to the comparator 19. In the comparator 19, the magnitude of the output value from the A/D converter 17 is compared with that of the output value from the slice level generator 18. The result is outputted to an accumulator 20, a timer 22, and an OFF detector 23. During the ON state of the signal of the comparator 19, the timer 22 converts the pulse number of a sampling signal to a time. During the ON state of the signal of the comparator 19, the accumulator 20 accumulates the output value from the A/D converter 17. After the elapse of a predetermined time, a signal for dividing the accumulated value of the accumulator 20 by the timer value of the timer 22 is issued to a divider 24. The result value of the exciting current (i) is outputted as digital numerical data.

Abstract: PURPOSE:To easily recover toner with this cleaning device by providing an electret having the same polarity as that of the toner inside a photosensitive body so that the toner repulses the electret and is easily removed from the photosensitive body. CONSTITUTION:When the photosensitive drum 1 is rotated like an arrow, and the toner T remaining on the surface of the drum 1 comes up to a position opposed to the cleaning device 8, repulsion occurs each other because the electret E inside the drum 1 has the same polarity as that of the toner T, and the toner T is easily removed from the surface of the photosensitive drum 1. The toner T in a state where it is easily removed is easily scratched off from the surface of the rotary drum 1 by the top end 9a of the cleaning blade 9 of a device 8. Especially, even the toner T which is hardly scratched off by the blade 9 such as spherical toner, is easily removed and scratched off by the synergistic effect of the toner itself and electrostatically repulsion by the electret E having the same polarity. The scratched off toner T drops in the device 8 and can be recovered, separately.

Title: Keyboard device and information processor
Inventor: KATAYOSE MAMORU
IPC: G06F3/023
Filed: 1990-07-02
Abstract: PURPOSE:To enable an operator to assign the definition of a specific key to a desired key by converting the definition set to a converting side key into that of a converted side key with use of a definition converting means. CONSTITUTION:An operator wants to change the definition of a specific key into that of another key among those keys 34, 35... owing to the inferior operability of the specific key. Under such conditions, the operator pushes a user definition key 36 to set a definition conversion mode. Then a fact whether a cancel key 38 is pushed or not is decided, and a control key 34 is pushed instead of the key 38. Thus the key 34 is recognized as a converting side key and a '0' character key 37 which is pushed next is recognized as a converted side key. Then the definition of the key 34 is turned into that of the key 37. Thus the definition of the key 37 serves as the definition of the key 34. In such a way, the definition of a prescribed key can be changed and therefore an operator can assign the definition of a specific key to a desired key.

Then, the chuck 13 is turned at a given revolving number, whereupon the resist is stretched into stringy form on the surface of the wafer 12, floated in the inside 18 of the cylinder, and adhered to a funnel-shaped metal netting 19. Thus, the entanglement of the stringy resist to the lower side of the chuck 13 and the rotary shaft 11 can be avoided. Also, the resist entangled to the netting 9 is washed off by resist dropped on the next wafer. Thus, a desired thickness of high-viscous resist can be formed on the surface of the wafer 12, and also washing can be simply performed because the netting 19 can be removed.
