Title: Checking method for read-only memory
Inventor: SAKURAI JINICHI
IPC: G06F12/16
Filed: 1979-03-22
Abstract: PURPOSE: To ensure the accurate checking with every word in a high speed, by adding the read/wirte memory RAM to read-only memory ROM as the checking bit and then writing the error check information into RAM before use of ROM.  
     CONSTITUTION: Before execution of the program via the computer, the contents of ROM10 are read in sequence, and data 5 is supplied to parity bit generating circuit 20. Circuit 20 generates parity bit writing data 12 to be then written into RAM15 by writing command 14. Such action is given to each word of ROM10, and then the desired program is executed. As a result, data 5 along with parity reading data 13 are supplied to parity check circuit 30 for execution of the parity check. Thus the high-speed and accurate checking is given to the reading data of ROM10 with every word.

Filed: 1988-02-18
Abstract: PURPOSE:To enable optimum throttle valve control according to the running condition of a vehicle by selecting either the control characteristics of the throttle valve opening or the engine speed which are stored in advance with respect to the control variable of the throttle valve. CONSTITUTION:A RAM 58 stores both the control characteristics A which determines the opening of a throttle valve 28 according to the amount of turn of a thumb throttle lever 40, that is, to the output of an angle sensor 42 and the control characteristics B which determines the running speed range or the running speed of an engine 14 according to the amount of turn of a thumb throttle lever 40. Responding to the output signal of a manual switch 44 making the mode selection, a CPU 52 reads out the characteristics A or B from the RAM 58 and determines the target opening or the target speed of the throttle valve 28. A driving circuit 66 then controls the motor 30 to obtain the target value. Therefore, when precise control or quick control is made for the throttle valve is made, the characteristics A may be selected and when the constant speed running is executed, the characteristics B may be selected.

Abstract: PURPOSE:To improve the system operating rate by providing a picture recording section, an information read section, a selection section, a buffer memory and a control section so as to process the information obtained from a different picture information acquisition section in parallel with simple control. CONSTITUTION:A start signal enters a selection section 16 from a read section 11. A control section 19 confirms the standby state of a recording section 10 to permit the start of read. Read information is stored in a buffer memory 18 to record the information at a maximum processing speed of the recording section 10. Recording paper is discharged by a sorter 14. When the recording operation corresponding to the read section 11 is finished, the recording corresponding to the read section 12 is immediately implemented. Moreover, when a recording operation start signal is inputted externally via an interface 13 in parallel with the copy processing, the selection section 16 confirms the standby state of the recording section 10 and allows the operation start and the interface 13 outputs the information of a page memory to the recording section 10. The recorded paper is distinguished from other recording paper and discharged. Since the read of a sheet original is kept during a book original copy by the read section 11 without time loss, the operation efficiency of the system is high.

Title: Infrared image sensing device
Inventor: HISA YOSHIHIRO
IPC: H04N5/33
Filed: 1989-02-14
Abstract: PURPOSE:To make a substrate arbitrarily large and to neglect a difference in a coefficient of thermal expansion between the substrate and a semiinsulating substrate by a method wherein the substrate part for individual infrared detection elements is separated spatially and metal electrodes are formed on the substrate in such a way that at least one part of the electrodes is bridged over a space part. CONSTITUTION:An n-type semiconductor layer 11 is formed partially on the surface of a p-type substrate 10; individual infrared detection elements 12 are separated spatially and are connected only by metal electrodes, i.e., p-electrodes 22, in such a way that space parts 10a are bridged. Accordingly, a mechanical stress caused by a difference in a coefficient of thermal expansion between the p-type substrate 10 and a p-type Si substrate 14 is absorbed spatially in a thermal hysteresis process when the elements are used or not used; since an increase or a decrease in a space at the individual space parts 10a is very small, a large stress is not caused at the electrodes 22. Thereby, a stress at a semiinsulating substrate 20 and the p-type substrate 10 can be neglected, and the p-type substrate 10 can be made large.

Abstract: PURPOSE: To make the chemical decontamination at the time of disposal of vessels easy by coating the epoxy resin varnish of good corrosion resistance to the iron-base vessels of the plant handling uranium hexafluoride gas in said plant.  
     CONSTITUTION: An iron pipe is coated by epoxy-resin-base varnish. When this pipe was exposed to uranium hexafluoride gas, it was confirmed that it suficinetly withstands uranium hexafluoride gas of high corrosion resistance. Hence, in order to decontaminate the pipe, it was subjected to immersion decontamination treatment with a dilute nitric acid and water, as a result of which the rate of contimnation of 1,000cpm dropped down to 9cpm. Further, if the one which is of a high rate of contamination and is difficult to be decontaminated is first rinsed with water and is then heated in an electric oven, then the varnish burns to carbon and the product of decomposition of the deposited urnaium hexafluoride becomes U 3 O 8  powder and peels from metal surfaces. As a result of this, good decontamination may be performed.
