Abstract: A method of electrodepositing a hard impact resistant and corrosion resistant film on the cathode of a unidirectional electrical system is disclosed in which a unidirectional electrical current is passed through an aqueous coating composition having a pH in the range of pH 4 to pH 6 comprising water having dispersed therein an hydroxy functional cationic resin comprising an adduct of a resinous polyepoxide having a number average molecular weight in the range of about 600 to about 6000 and an hydroxy value of from about 0.2 to about 0.4, this resinous polyepoxide having its molecular weight optionally increased by reaction with a stoichiometric deficiency of organic polyisocyanate, with a mixture of monosecondary amines in an amount to consume substantially all of the epoxy functionality of said polyepoxide in the formation of tertiary amines by reaction of the monosecondary amines with the oxirane groups of the polyepoxide. This mixture of monosecondary amines comprises a mixture of diethanol amine and dibutyl amine in molar proportions within the range of 1:2 to 2:1. The cationic resin is dispersed in the water by means of neutralization with a volatile organic acid to an extent of at least 80%, and the electrical current passes through the cathode to deposit a resin film thereon, which is then usually rinsed and baked to cure the same. The mixture of monosecondary amines provides good bath stability combined with electrical deposition characteristics in the cathodic electrodeposition process.

Abstract: A measurement is carried out on a medium that propagates energy in a selected form by applying energy in the selected form to the medium, the power varying as a function of time in accordance with the elements of two Golay complementary sequences where one kind of element is represented by zero power and the other kind of element is represented by a prede­termined non-zero power level and the successive elements of each sequence are applied at uniform intervals. Energy emitted from the medium in the selected form is received, and the variation as a function of time of the power emitted is correlated with the variation as a function of time of the power that was applied. Preferably, the level at which power is applied is varied both directly, in accordance with the elements of the two Golay com­plementary sequences, and in a derivative fashion, in accordance with the logical complements of the two Golay complementary sequences.

Abstract: According to the invention, the peripheral function units (6) consist of combined binary transmitter and adjusting devices and the information transmission is initiated by the central control device (1) by sending out a data word consisting of an address section and a data section. To ensure high clock rates for the acquisition and output even when the address decoding of a peripheral function unit fails, in connection with which optional access to any peripheral function units must be made possible and interactions between address and location of the connection of the peripheral function units at the transmission channel must be eliminated, the parallel data words are transmitted, after having been converted unclocked into serial data words in a device for parallel/serial conversion (3), to the peripheral function units (6; 6' etc) in a first transmission channel (5). In this channel, the serial data word is both forwarded and analysed. When the address is detected, the information contained in the serial data word is processed in accordance with the task set and sent in the response signal to the central control device (1). <IMAGE>

Abstract: A ring network data transmission system includes a plurality of transmission apparatuses (1, ..., N), terminals (1 a , ... , N c ) each connected to each of the transmission apparatuses and double ring trans- mission paths (O a , O b ) interconnecting the transmission apparatuses in a ring-like system configuration so that terminals can communicate with one another through the associated transmission apparatuses. When transmission faulty occurs in the network, the transmission apparatus which can serve as the master station issues to all of the other transmission apparatuses a command for searching the fault location. In response to the reception of the command, each of the other transmission apparatuses sends out a monitor signal containing its own address and at the same time checks the monitor signal as received. Through collation of the address contained in the received monitor signal with the address information arrayed in the order in which the transmission apparatuses are interconnected, the number of bypassed transmission apparatuses existing between each transmission apparatus and the transmission apparatus sending out the monitor signal is determined. By comparing this number with a predetermined maximum permissible number of the stages allowable to be bypassed, the faulty location is detected. With such an operation, automatic reconfiguration operation of double ring network can be stabilized.

Abstract: A large-frame image (21) is divided into image pieces (23) each having a predetermined two-dimensional size, and the image pieces are divisionally stored in a plurality of optical disk devices (22-1 through 22-4) which can be parallelly accessed. Each disk stores division management information (an array position of each image piece on the large-frame image, and pointer information (optical disk number, and optical disk track number) indicating a storage position in the optical disk). A CPU (11) generates a storage destination information table in a main memory (15) in accordance with the division management information stored in each disk device. The storage destination information table represents a storage destination of each image piece in correspondence with its two-dimensional array position on the large-frame image. The CPU designates an access destination in units of disk devices, and simultaneously issues an access request to parallelly read out unit images.
