When the signal of the write signal line does not exist, the RAM 21 is made readable. On the other hand, in the case of the memory area where the access is prohibited and impossible, the action is completed. Thus, even after the input of a power source, the write/read action to the RAM 21 can be freely set.

IPC: G06F17/30
Filed: 1986-08-04
Abstract: PURPOSE:To decrease the quantity of data to be transmitted by transmitting independently position information showing a range where the same retrieving command is sent to an information center and the information on a conversion table which converts an indicated range into the retrieving command. CONSTITUTION:Position coordinates supplied from an input part 25 are compared with the position information (obtained by dividing a screen into optional geographical patterns with numbers added to each pattern) showing a range where the same retrieving command received from an information center 1 is sent to the center 1. Then said position coordinates are converted into the numbers of graphic elements including coordinates. These numbers are converted into the retrieving commands and sent to the center 1 with reference to the information on a conversion table which converts an indicated range received from the center 1 into a retrieving command. As a result, the desired screens are sent to a user terminal 20 from the center 1. Then a desired retrieving command is obtained by sending only a new conversion table to the terminal 20 as long as the position information is equal between a display screen and the next one.

Title: Production of silicon-contained cast iron
Inventor: UCHIDA SHIGETAKA
IPC: C21C1/08
Filed: 1987-07-23
Abstract: PURPOSE:To stably produce a spheroidal graphite cast iron which is a raw material for castings having excellent mechanical strength and toughness by subjecting the molten iron tapped from a blast furnace to hearth desiliconizing, desulfurizing and dephosphorizing treatments, then adjusting the contents of carbon and silicon and spheroidizing graphite with Mg. CONSTITUTION:The molten iron 23 tapped from the blast furnace is predesiliconized by blowing a desiliconizing agent 25 such as mill scale, etc., on a blast furnace hearth 22. This molten iron 23 is put into a molten iron ladle 27 and molten slag 26 is scraped out. A CaO flux is then added to the molten iron to slag off and remove S in the molten iron as CaS and to desulfurize the molten iron to about 0.001%. After the molten slag of this time is discharged, a dephosporizing agent consisting of fluorite and millscale is added to the molten metal and oxygen is blown to remove P in the molten iron as P2O6-contg. molten slag. The content of C is adjusted to 3.4-3.8% and thereafter, metal silicon or ferrosilicon is added to the molten iron and oxygen is blown to increase the temp. of the molten metal by the oxidation heat of Si and simultaneously to adjust the content of Si to >=0.5% with the unoxidized Si, following which an Mg graphite spheroidizing agent is added to the molten iron to spheroidize the graphite shape of the molten iron to a flake or spheroidial shape. This molten iron is cast into a casting mold, by which the spheroidal graphite cast iron casting having the excellent strength and toughness is produced.

Title: Operating mechanism of four-wheel drive car
Inventor: IWATA SEIICHI
IPC: B60K23/08
Filed: 1981-11-13
Abstract: PURPOSE:To prevent an erroneous operation by mechanically locking so as not to allow a shift to an emergency low (EL) speed change stage while running at a two-wheel drive in a speed changer incorporating an EL speed change stage gear with a larger gear ratio than that of the first speed. CONSTITUTION:When a shifter rod 28 is placed at the select position of the first speed and the second speed, for instance, by a change lever operation while running at a two-wheel drive, the selector bar 31 of a selector unit 30 is coupled with the shifter arm 25b of the speed changer side, then if a shifter rail 25 is moved, the first speed is available. At this time, the tip section 42a of an arm 42 is not coupled with a coupling lug 41 and serves for nothing, but if the shifter rod 28 is rotated to the right and is placed to the selector position of an EL speed change stage and reverse stage, the arm tip section 42a is coupled with a protruded section 41b, thereby a shift to an L speed change stage is blocked. On the other hand, when running at a four-wheel drive, the arm tip section 42a matches the recessed section 41a of the coupling lug 41, thus allowing a shift to the EL speed change stage.

Abstract: PROBLEM TO BE SOLVED: To automatically feedback an electronic document to the person responsible for the wording of deficient items and to efficiently execute work by selecting the deficient items when an operator detectes deficiencies in the electronic document and executing a feedback operation. SOLUTION: An examinater looks at a slip screen displayed on the display part of an examinater's terminal equipment 1, and checks whether the deficiencies exist in the entry items. When the deficiencies do not exist in a payment slip as the result of the examination, an 'OK' key is depressed, and a 'feedback' key when the deficiencies exist. When the terminal equipment 1 recognizes that the deficient item column is selected, identification information on the person responsible for the wording of the deficient items is inquired from a server computer.  The server computer retrieves the name of the person responsible of wording and a network address with respect to the deficient items from a responsibily table which is previously generated for the inquiry, transmits them to the terminal equipment 1 being an inquiry source and displays a message for recognizing a deficiency feedback and the identification information on the person responsible for the wording on the screen.
