Title: Target for survey instrument
Inventor: NAKAMURA KYOJI
IPC: G01C15/06
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To enable the smooth collimation of a survey instrument by a telescope, etc., by providing a linear part constituting a collimation pattern and a lower-contrast regions than the linear part which are arranged along both sides of the linear part. SOLUTION: A target 9 for a survey instrument comprises a cross line part 4 which is a collimation pattern and low-contrast regions 5 arranged along both sides of the line part 4a on a reflecting sheet 7 which is formed in the shape of e.g. a sheet and on whose surface corner prism-shaped fine bodies are placed. The point of intersection 4a between the vertical and horizontal lines of the line part 4a is the center of the target 9. The regions 5 are approximately of the same pattern as the line part 5 and arranged so as to sandwich the line part 4 with lines of the approximately same width. The color of the regions 5 are e.g. white, and that of the line part 4 is e.g. black. As the emission of reflected and scattered light of sun light, etc., is suppressed around the line part 4, it is easier to see the line part 4.  It is possible to narrow the line width of the line part 4 for improving measurement accuracy.

Title: Ignition timing control method of engine
Inventor: YAGI KATSUNORI
IPC: F02B31/00
Filed: 1984-02-03
Abstract: PURPOSE:To aim improvements in the output of power in an engine and its drivability, by preventing the occurrence of knocking at an engine high load range where a swirl develops. CONSTITUTION:Setting A/F suddenly varies from the lean side to the rich side at an interval between both maps MP1 and MP2 so that prescribed ignition timing (curve Q) shows a specified variation. Therefore, ignition timing thetaM being found by an interpolative calculation as in the past suffers a sharp slippage with the prescribed ignition timing at a section of PM=PM2-PM3 whereby there is a possibility of causing a knock and dropping the engine output. In contrast to this, a lag timing advance is compensated with a fixed value C subtracted from the igntion timing thetaM found by the interpolative calculation shown in a straight line P, so that a swirl control value is opened. At that point that suction pipe negative pressure PM comes to PM3, the lag timing compensation is stopped whereby the ignition timing is controlled in a state of approximating to the prescribed igntion timing.

Abstract: PURPOSE: To provide a communication right to a terminal station quickly an impartially by allowing a host station to conduct polling transmission with a data packet including 1st and 2nd codes and revising the sequence of occurrence of the 2nd code for each unit polling period. CONSTITUTION: A host station 11 generates a 1st code and a 2nd code in a desired order to divide all terminal stations into one or plural groups and sends them to each terminal station in a way of polling.

The host station provides a communication right to the terminal station when no communication collision takes place in the received request and updates 1st and 2nd codes or only the 2nd code when communication collision takes place and continues the polling. Furthermore, the host station uses a divisor P as the 1st code and uses a residue (m) as the 2nd code.  When each terminal station discriminates the polling to be addressed to its own station when the residue of the identification value of its own station divided by the divisor P is coincident with the residue (m).

Abstract: PURPOSE:To simultaneously form insulator regions having different depths used to isolate an element by forming ion implantation layers having different depths using mask layers having different thickness according to the place formed on a semiconductor substrate and heat treating them. CONSTITUTION:Holes 14, 15 are opened at an Si substrate 11 covered with an SiO2 layer 12 and an Si3N4 layer 13. In the hole 14 the SiO2 layer is also removed, but in the hole 15 the SiO2 layer is retained. When oxygen ions are injected thereto, they are injected deeply to the hole 14 and injected shallowly to the hole 15. Thereafter, this is thermally oxidized to rapidly oxidize the region where the oxygen ions are injected, and insulator regions having different depth can be formed. Thus, the insulator regions having different depth can be formed by one step.
