Title: Data communication method in on-vehicle communication network
Inventor: KIMURA TOSHIYUKI
IPC: H04L12/00
Filed: 1990-10-25
Abstract: PURPOSE:To make it possible to put a relevant onboard communication network in an operable state without issuing polling when the master unit is recovered by continuously sending connection request information to a communication bus until receiving an answer of receiving confirmation information from the master unit periodically even when the network is enters the power consumption mode. CONSTITUTION:When answer of connection information from the master unit 200 is ceased, each slave unit 200-1-200-n, when a predetermined detecting period of time passes, enters the low power consumption mode. However, after that, each slave unit 200-1-200-n automatically switches its own operation mode from the power consumption mode to the mode of issuing connection confirmation request information periodically or at arbitrary timing and repeats answering connection confirmation information. This repeat operation is continues until receiving answer of connection confirmation information from the master unit 200. This retry action enables the AV system to be completely recovered.

Title: Method and mechanism for matching optical component connection surface
Inventor: FUJIWARA SHIGERU
IPC: G02B6/24
Filed: 1995-11-07
Abstract: PROBLEM TO BE SOLVED: To easily and securely match surfaces without confirming the surface matching. SOLUTION: Against the end surface of one optical component 11 which is fixed, the end surface of the other optical component 49 is pressed, but the optical component 49 is supported by a component holding body 43 so that it can slant, so the tilt can easily be changed so as to match the end surfaces of both the optical components. The tilt is changed by moving the optical component 49 pressed against the optical component 11 by a specific quantity at right angles to a Z axis as the pressing direction. In this case, a table showing the relation between pressure values of a pressure sensor 51 and Z-axial movement quantities is stored as data and then a Z-axial movement quantity can easily be obtained from the table. Further, the value at which a point which comes into contact first when the end surface is pressed begins to slip by the movement of the optical component is regarded as the pressing force.

Title: Measurement of semiconductor device
Inventor: SUGAWARA JUNJI
IPC: G01R31/30
Filed: 1985-12-20
Abstract: PURPOSE:To accurately measure a noise margin by dividing one pattern among the input patterns of a semiconductor device and applying different voltage values to divided segments. CONSTITUTION:A modified pattern B is generated such that one pattern of an original patterns A is divided into two and input voltages VIH' or VIL' and VIH or VIL are applied to the first and second halves of the divided original patterns, respectively. Input patterns are changed over at timings (a), (b), (d), (f), (i), and (j). A large current flows in a semiconductor device with relation to the timings, resulting in a voltage drop and the like, and a malfunction is apt to be caused in the semiconductor device. By setting the H level of the timings (a), (d) and (i) to VIH, higher than the voltage VIH of the pattern A and setting the L level of the timings (b), (f) and (j) to VIL' lower than the voltage VIL of the pattern A, the operation of the semiconductor device is stabilized because the H and L levels are not operational critical values. At the timing whereat the operational critical value is applied, the input pattern is not changed over from H to L or from L to H. Therefore, there arises no power supply voltage drop and the like and the operational critical values VIH and VIL representing noise margin can be measured.
