Title: Ignition timing control device
Inventor: MATSUMOTO KATSUO
IPC: F02P5/145
Filed: 1986-04-01
Abstract: PURPOSE:To ensure a proper ignition timing with a simple constitution, by detecting a position of a needle of a speedometer, and selectively outputting either of two kinds of ignition timing signals having different ignition timings to an ignition device according to the result of detection of the needle position. CONSTITUTION:When a vehicle is stopped at starting of an engine, a needle 21 of a speedometer indicates a scale of zero, and accordingly a switch 17 senses a magnetic force of a magnetized member 24 mounted on the needle 21 to maintain a closed condition. As a result, an ignition timing signal generating circuit 16 outputs a second ignition timing signal to a thyrister 13b in a CDI unit 13, and an ignition device 11 ignites an ignition plug 15 at a timing according to the output. On the other hand, when the vehicle starts running, the needle 21 of the speedometer is rotated, and a distance between the magnetized member 24 and the switch 17 is increased to open the switch 17. As a result, the circuit 16 outputs a first ignition timing signal having a relatively quick ignition timing.

Title: Signal processing device for af video signal of electronic control type camera
Inventor: SUZUKI NOBORU
IPC: H04N5/335
Filed: 1987-03-26
Abstract: PURPOSE:To obtain suitable distance information by expanding an AF video signal up to the vicinity of the suitable processing scope limit of an A/D converter and executing the gain control. CONSTITUTION:A light receiving sensor 20 starts the accumulation of a signal charge based on a driving command signal phiint of a CCD driving circuit 20' and the signal charge is outputted as an AFF video signal based on a driving command signal phiAD. The AF video signal is inputted to a dark sampling hold circuit 35 and an autogain control circuit 37. Here, when it is dark and an object contrast is lower, a low contrast corresponding level difference, which is the level difference between the low luminance equivalent level of the AF video signal and a high luminance equivalent level, is smaller. The autogain control circuit 37 amplifies 39 the AF video signal and outputs in to an A/D converter 34 so that the low contrast corresponding level difference can be close to the high contrast corresponding level difference when the object contrast is higher. Thus, distance measuring information comes to be larger and a distance measuring error comes to be smaller.

Abstract: PURPOSE:To stabilize well potential, to reduce the level of noise and to increase alpha-ray resistance by a device wherein between a well region and a substrate is formed a buried layer having the same conductivity type as that of the well region and higher density than that thereof, in the structure of a CMOS memory cell. CONSTITUTION:Between an N type substrate 1 and a P well region 2 of low impurity density and high resistance is formed a P<+> type buried layer 5 having higher density and lower resistance than that of the well region 2, right below an element region. Due to the presence of this P<+> type buried layer 5, impedance of the well region is lowered and there occurs no coupling between the N<+> type region 3 and the well region 2. As a result, well potential is stabilized, a level of noise in the memory cell section is reduced and penetration of alpha-ray can be prevented.
