Title: Electronic controller
Inventor: TSUJI KATSUNAO
IPC: H04Q9/00
Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To improve considerably the control reliability by providing required control information from other control means to a control means starting the operation from the initial state. SOLUTION: Control means ECUs 2, 4, 6 interconnected by a communication line 8 send a required request items necessary to control each control variable to other ECU normally and each control is executed by using returned data. Furthermore, when microcomputers of the ECUs 2, 4, 6 start processing from the initial state, notice information to report the operation from the initial state to other ECU is sent. Proper control is executed and the control reliability is improved considerably by sending/receiving control information required from other control means in the initial state and the normal state.

Title: Data path confirmation system and communication line check system
Inventor: FUJIOKA YASUSHI
IPC: H04L12/26
Filed: 1989-09-20
Abstract: PURPOSE:To execute path confirmation and line check in a multiplexer by detecting a channel number assigned to a data from a relay exchange and comparing the order of the returned data in a frame with the detected channel number to detect a data path. CONSTITUTION:A channel number assignment section 511 processes a channel number defined in the arrangement order of channels so as to be assigned as a dummy signal added for data format conversion. The arrangement order of channels in a data returned from the relay exchange 1 is replaced according to the exchange function of the relay exchange 1. Then a data path detection section 522 compares the order of data returned from the relay exchange 1 with a channel number assigned to the data returned through the detection by the channel number detection section 521 to execute the detection of the data path exchanged with the relay exchange 1. Thus, the check of a communication line 2 between the relay exchange 1 and the multiplexer is executed accurately in the multiplexer.

Title: Rewriting type phase change optical recording medium and production thereof
Inventor: SUGIYAMA YASUYUKI
IPC: G11B7/243
Filed: 1988-09-30
Abstract: PURPOSE:To control the amorphous and crystalline properties of the medium at the time of production of the medium so that both of the stability and high-speed erasing of the recording state are attained by allowing fine crystals which are the nuclei for crystallization approximately uniformly into an optical recording layer at the time of the production in the amorphous state. CONSTITUTION:This recording medium consists of a transparent protective layer 1, the optical recording layer 2, a substrate 3, fine crystal-contg. amorphous pits 4, and random amorphous pits 5. The medium in which the fine crystal exists is uniformly crystallized as an initial state by irradiation of a laser; thereafter, the fine crystal-contg. amorphous pits 4 are formed. The initial fine crystals remain when the medium is made int the amorphous state by the irradiation of the laser at the time of recording; in addition, the crystallization progresses in the crystalline state around the amorphous pits 4 with the initial fine crystals as nuclei; therefore, the grain size is reduced and the medium noises are decreased. The residual fine crystals acts as the nuclei of crystallization if the crystallization by the irradiation of the laser is executed at the time of erasing and, therefore, the crystallization progress rapidly. The erasing speed is increased in this way and the optical recording medium having the excellent stability of the recording state and the repetitiveness of the recording and erasing is obtd.

Abstract: PURPOSE:To enable amount of calculation to be reduced and identification operation to be performed efficiently by detecting peak values from an actually measured spectrum data of an unknown sample and that of a known substance which is collected in a library and then performing comparison only for peak values for two spectra. CONSTITUTION:Spectrum measurement of an unknown material is performed and spectrum data are stored in memory. Then, a peak value is detected from measurement result and the position and strength are memorized. When operation is completed for all peak values of measurement result, one spectrum data out of several candidate substances is read out of a library. When identifying an unknown sample, since a range of a substance to be retrieved for identification is limited to some extent, substance to be retrieved for identification is limited to some extent, substances within that range are selected previously as candidate substances from various kinds of information and reading is made in order from that location. A peak value is detected from the read-out data and the position and strength data are memorized. When operation is completed for all peak values of read out data, degree of correlation with each peak value of spectrum data which are read out of the library is calculated for each peak value of an unknown sample spectrum.

IPC: H04L12/42
Filed: 1991-08-30
Abstract: PURPOSE:To relieve the load of a monitor node by supplying power to a bias control section for a prescribed time when each node detects power interruption of other system so as to interrupt forcibly a transmission output of the other system. CONSTITUTION:When a 1-system power supply 3 is interrupted, a 0 system timer 6 of a power supply other system supply circuit 4A drives a 0 system relay 8 for a prescribed time to supply power to a 1-system bypass control section 22. Thus, a transmission output of the l-system is interrupted for a prescribed time, the system is switched to the 0 system. Conversely, when the 0-system power supply is interrupted, power is supplied to a 0-system bias control section 12 to switch the system to the 1-system. Thus, the monitor node executes the system changeover without notifying the bypass state due to one- system power supply interruption to suppress the increase of the load of the monitor node.
