PURPOSE:To facilitate the teaching work, by turning on and off an operation changeover switch of a solenoid valve in accordance with the rotation direction of a steering operation wheel. CONSTITUTION:When a steering operation wheel 11 is rotated in a desired operation direction, one of the first and the second switches 19a and 19b is turned on or off to switch the solenoid valve. Simultaneously, a...

PURPOSE:To make a high-precision automatic traveling possible, by providing an actuator operating means which turns a steering wheel in the reverse direction for a certain time after turning the steering wheel up to one steering angle limit. CONSTITUTION:In a controlling circuit of a solenoid valve, a one shot circuit 20 generates an output signal for a certain time by the rise of turning-on of a ...

PURPOSE:To improve the reliability of a controller and the safety of a control device, by counting the number of times of restart of a program after resetting and holding the device to be controlled in the safe state when this number reaches a set value. CONSTITUTION:Switches of an address set circuit 14, a data set circuit 15, and a control signal set circuit 16 are operated to set prescribed val...

PURPOSE:To prevent the occurence of judder noise of a movable plate of a friction-type electromagnetic clutch brake, by pressing and supporting an elastic body on one surface of a cup-shaped armature by a face plate which is made of metal or the like and does not cover the whole of the free surface of the elastic body. CONSTITUTION:A friction material 1 for braking is stuck on one surface of a cup...

A process for producing a multi-layer coating upon a substrate surface, in which there is first applied to the surface a pigmented basecoat composition and then there is applied to the basecoat film a transparent topcoat composition; characterized in that the basecoat composition is based upon a dispersion in an aqueous medium of crosslinked polymer microparticles which have a diameter of 0.01-10 ...

PURPOSE:To shorten the processing time, by operating manifoldly the load or store processing and logical operations while shifting their timings little by little in a parallel processing device where many data are operated with a single instruction. CONSTITUTION:A vector register device 2 consists of 4 vector registers VR0- VR3, and each VR includes 8-word element data having element numbers 0-7. ...

PURPOSE:To improve the processing speed of the vector operation, by executing the parallel vector processing and the common vector processing in individual private devices, and accessing simultaneously vector registers by systems suitable for respective processings. CONSTITUTION:A vector register device 11 is provided with independent vector registers VR0-VR3, and each VR includes numbered element...

PURPOSE:To prevent the occurrence of errors, by generating an identification code on a basis of a vector element number to detect the step-out of synchronism between a controlling part and a pipeline operating part for the pipeline of every element of a vector operation instruction. CONSTITUTION:A vector processing system consists of a controlling part 1 and a pipeline operating part 2, and the ou...

A photopolymerizable composition which comprises at least one ethylenically unsaturated polymerizable monomer, at least one selected ketone and at least one organic peroxide. The compositions are useful in the preparation of adhesives, paints and varnishes particularly in dental applications and exhibit reduced air inhibition on being cured by visible radiation in the range 400 m mu to 500 m mu .

A loading pallet comprises an essentially flat deck and at least four feet bearing the latter. Previously known loading pallets are of a heavy construction, they are not easily stackable and, in particular, in the stacked state, they take up a large amount of space and are not easy to handle. According to the invention, the feet (2) of the loading pallet are of open design and are essentially U-sh...

PURPOSE:To measure accurately the response time of a terminal in the host side, by obtaining differences of data transmission and reception times between a CPU and a communication control processor CCP and between the CCP and the terminal. CONSTITUTION:Just before data is transmitted from a CPU 1 to a CCP 4, a response controlling part A3 sets a time t1 read from a timer 2 and indicates that this ...

A method of fabricating a composite structure wherein a porous laminate comprised of a plurality of plies of fibrous material in an uncured resin matrix has entrapped air expelled. In carrying out the method, the laminate is positioned in an evacuable chamber. Vacuum is applied to the chamber to create a partial vacuum environment therein. The laminate is heated to within a temperature range where...

PURPOSE:To perform the debugging work efficiently, by transferring the control to a debugging routine only when a prescribed value is written in a storage means corresponding to a debugging instruction during the execution of a program to be debugged. CONSTITUTION:A bit E2 of a constitution register 11 is used for debugging and is set to 1 in response to the change of a memory. Bits TV, SL, EP, SS...

New antineoplastic glycosides, phyllanthostatin 1, 2 and 3, and the related glycoside, phyllanthoside, have been isolated from the Central American tree, Phyllanthus acuminatus Vahl. These compounds exhibit activity against the National Cancer Institute's P388 lymphocytic leukemia. Also, phyllanthoside was found to possess a curative level of activity against the murine B16 malanoma.

A compound of the formula: wherein X<1>, X<2> and X<3> are each amino or protected amino, X<4> is hydrogen or hydroxy, R<1> is hydrogen or lower alkyl, and R<2> is higher alkanoyl which may have one or more suitable substituent(s), higher alkenoyl, or higher alkylcarbamoyl, or pharmaceutically acceptable salt thereof, processes for its preparation, pharmaceutical compositions containin...
