Title: Misfire detection method for internal combustion engine
Inventor: YOSHIMURA MAKOTO
IPC: G01M15/00
Filed: 1990-10-19
Abstract: PURPOSE:To enable high-precision misfire detection by providing gear ratio detection means and a clutch ON/OFF state detection means and changing the misfire determination condition according to the outputs in the misfire detection from engine rotational fluctuation. CONSTITUTION:During operation of an engine, in a control circuit 15, a reference comparative rotational speed B(n) is obtained from a rotational speed (n) obtained by an engine rotational sensor 1 and then the clutch on/off state is determined. When the clutch is ON, a misfire determination level (f) is obtained on the basis of the gear ratio (g), the engine load l and the engine rotational speed (n). Then, the value obtained by subtracting the engine rotational speed (n) from the reference comparative rotational speed B(n) is compared with the misfire determination level (f), and when the misfire determination level (f) is larger than the other, this is determined as a misfire. When the clutch is off, on the other hand, a misfire determination level (h) is obtained from the engine rotational speed (n) and the engine load l. The value obtained by subtracting the engine rotational speed (n) from the reference comparative rotational speed B(n) is compared with the misfire determination level (h). When the misfire determination level (h) is larger than the other, this is determined as a misfire.

IPC: G08B23/00
Filed: 1992-09-04
Abstract: PURPOSE:To reduce the operating cost of a security system by providing a surge-voltage limiting device, an electric-leakage breaker and a reset circuit.

Title: Map display device
Inventor: TANIGUCHI TOSHIHIKO
IPC: G01C21/00
Filed: 1994-11-14
Abstract: PURPOSE: To suppress the increment of size in the whole display device even in the case of improving the sensitivity of an antenna and to ease a change in the directional sensitivity of a built-in antenna due to the supporting procedure of the display device by specifying the arrangement of an antenna storing part and the antenna itself. CONSTITUTION: The antenna storing part 5 is projected to a display face 20 of a display means 2 and built in and arranged on the upper part of the means 2 so that a receiving face 10 of a present place detecting means 1 is inclined from the display face 20. Thereby even if a wide antenna area is secured, the top panel of a display device body is not expanded and also the size of the display device itself is not increased, so that the device can easily be carried.  Since the inclined antenna arrangement is constituted so that the fixed receiving face 10 released from the top panel can be secured even when an observer observes the display face 20 while supporting the display face 20 horizontally to the ground or when the observer lifts up the display device so that the display face 20 is held at the height of an observer's eyes, a change in the directional sensitivity of the built-in antenna due to observing posture can be eased.

Abstract: PURPOSE:To eliminate a decrease in the quantity of a scanning beam by using the signal from a photodetector as a timing clock signal for photoscanning speed compensation. CONSTITUTION:A figure (a) shows that a hologram disk substrate 2 is fixed on the driving shaft of a motor 1 and rotated. A hologram part 3 which deflects a light beam is formed annularly on the substrate 2 as shown in a figure (b) and the light beam from a beam source which is not shown in the figure is deflected to obtain the scanning beam. A pattern 4 for clock timing which have a light transmission part and a light nontransmission part arranged alternately is formed annularly at the outer periphery of the hologram part 3; and a reference light source 5 and a lens 6 are arranged on one side of the pattern 4 and the photodetector 7 is arranged on the other side. The projection light from the light source 5 is intermitted by the pattern 4 and converted by the detector 7 into an intermittent electric signal, which is used as a timing clock signal for compensating a photoscanning speed. Thus, the light source 5 is provided independently as a light source for obtaining the timing clock signal without being branched from the light source for the scanning beam, so there is no decrease in the quantity of the scanning beam.

Title: Manufacture of semiconductor circuit
Inventor: TERAYAMA KAZUYOSHI
IPC: H01L21/027
Filed: 1984-12-26
Abstract: PURPOSE:To double the yield of high quality semiconductor elements obtainable from one wafer by overlapping the circuit patterns of both sides to form the reverse side circuit using the positioning patterns prepared on the right side of the wafer. CONSTITUTION:The present invention relates to a pattern printing process i.e. the PR process which is attempted on both sides of a wafer. For this purpose, two target patterns 6 for position overlapping are printed on suitable two positions of the mask pattern 1. Before the PR process is applied to the reverse side of a wafer, following that applied to the right side, absolute position overlapping of both sides is made in such a manner that a penetrating radiation such as infrared light is penetrated through the wafer 8 from its right side in order to set the position of the mask 7. this can done because the photoresists 9 remain on the targets so that the target patterns can be detected with the detectors 11 due to the difference of absorbancy for infrared light etc. Thus two identical circuit patterns are prepared on both sides of the wafer, followed by the sorting of dies.

Title: System abnormality accumulation device by mask-type buffering
Inventor: EBISAWA YASUSHI
IPC: G06F11/34
Filed: 1995-10-27
Abstract: PROBLEM TO BE SOLVED: To shorten the time of the analysis of abnormality primary factor by providing an initial abnormality accumulation buffer in an accumulation circuit and collecting and accumulating only initial abnormality information with a mask circuit. SOLUTION: System abnormality is roughly divided into CPU abnormality 20, software abnormality 30 and peripheral unit abnormality 40. All pieces of abnormality information are gathered in an abnormality information collection/delivery processing and are transmitted to the accumulation circuit 50. The accumulation circuit 50 accumulates all received abnormality information in a time sequential accumulation buffer 60 and accumulates only initial abnormality information in an initial abnormality accumulation buffer 80 through a mask circuit 70. Thus, same abnormality which repetitively occurs like peripheral unit abnormality 40 is filtered by making information pass through the mask circuit 70 and only initial abnormality information is accumulated. Thus, narrowing in the pursuit of a cause becomes facile in the analysis of the abnormality primary factor and analysis time is shortened.
