Abstract: PURPOSE:To prepare effectively a laminate contg. an ethylene-vinyl alcohol copolymer as at least one layer by incorporating a random copolymer contg. at least an ethylene component and a radical-polymerizable acid anhydride component as an adhesive layer. CONSTITUTION:An ethylene-vinyl alcohol copolymer is obtd. by saponifying an ethylene-vinyl acetate copolymer and consists of 20-70mol% ethylene and 30-80mol% vinyl alcohol. An adhesive layer used is a random copolymer contg. at least an ethylene component and a radical-polymerizable acid anhydride component obtd. by incorporating a compd. contg. 2 or more double bonds in a molecule when polymerized. The content of the radical-polymerizable acid anhydride component in the random copolymer is pref. in the range of 0.1-5mol% and especially pref. 0.3-2mol%. When said acid anhydride is less than 0.1mol%, an interlaminar adhesive force is not sufficient and when it is above 5mol%, a profitable production thereof becomes very difficult.

Title: Memory control circuit
Inventor: SAKAGAMI WATARU
IPC: B41J2/485
Filed: 1986-03-19
Abstract: PURPOSE:To store data in accordance with the bit format of output elements by providing a means inserting a blank with the prescribed length into input data and storing the input data by a data array matching to the length of a string made of the output elements. CONSTITUTION:Where the width of an interface bus I/FB and a variable amount are eight bits and +3, respectively, PT=1 and BW=1 hold. Accordingly the output 816 of an AND gate 816 comes to '1', and the outputs 801a and 801b of a ternary counter 801 are outputted to address signals A0814 and A1815. If the variable amount and the width of the I/FB are +3 and 16 bits, respectively, BW=0 holds. As a result a gate 816 is inhibited, and the output 816a becomes zero. Outputs 802a and 803a are outputted to outputs 814 and 815 from an AND gate 813. Where PO812=0 and PT=1 hold, an AND gate 808 becomes enable, and a binary counter 803 is increased by '1'. Where the variable amount and the width of the I/FB are +3 and 16 bits, respectively, automatically +1 is attained, and moreover, a mode where the address signal A0814 never changes can be obtained.

Filed: 1988-03-15
Abstract: PURPOSE:To prevent a transferring belt and an electrostatic latent image carrier from adhering, rubbing, etc., each other, to extend the service life of copying device, and to simultaneously, prevent trouble of said device by separating the transferring belt from the electrostatic latent image carrier when the copying device is left alone. CONSTITUTION:After the trailing edge of a transferring sheet S passes through a transferring part 11, the transferring belt 1 reversely revolves, whose upper belt part moves in the opposite direction of an arrow A, and prepares for a next transfer, namely, an overlapping transfer of various colored toners. When the transferring belt 1 moves in the opposite direction, an eccentric cam 23A coaxial with an axis 23, as a means to separate the transferring belt 1, revolves by 180 deg.; therefore, a frame 1A engaged with the eccentric cam 23A is lowered to a position shown by an alternate long and short dash line. On the other hand, when the transferring belt 1 moves in the direction of the arrow A to transfer a next toner image onto a transferring sheet, the frame 1A returns to an original position by the eccentric cam 23A. Thus, the transferring belt and the latent image carrier are prevented from being damaged and adhering to each other.

The core prints 13a, 13b, 14a, 14b are embedded by casting with the molten Al alloy intruding into the clearance S. Even if the casting removed by knocking out the top, bottom, right and left molds is hardened immediately as it is in water, the entry of the water into the cores is prevented by the parts embedded by casting. The core prints are removed by cutting after the hardening treatment and thereafter the casting is oscillated to collapse the sand of the cores 11, 12, by which the sand is easily removed from the casting.

Title: Hot-water supply controller
IPC: F16K31/06
Filed: 1992-03-17
Abstract: PURPOSE:To improve the reliability of operation in a selector valve by opening a flow regulating on-off valve after ensuring the selection of an outflow passage in the selector valve first of all, no matter what it may be opened to which passage, in the case where this flow regulating on-off valve is opened. CONSTITUTION:When a hot water supply is started by a setting means 17, even in the case where it is carried out through the same passage as a passage used at the last time, a flow regulating on-off valve 20 is opened after energizing a third coil 50 so as to have a selector valve 39 switched first of all. When a signal for starting the hot water supply inputted into a control means 18 from the setting means 17, this control means energizes the third coil 50 so as to be energized in the opening direction of the selector valve in time of the hot water supply at the last time. Supposing the passage was opened to an outflow passage 40 at the last hot water supply, this time, a first valve element 44 in the selector valve 39 ought to be already opened. However, this operation is carried out in order to raise its reliability. When this energizing time is over, the control means 18 receives this signal and starts its current- energization to a second coil 35 in order to open the flow control on-off valve 20 after the elapse of the specified time.

Title: Determining method for equivalent circuit element constant of electric circuit
IPC: H01L21/66
Filed: 1992-03-17
Abstract: PURPOSE:To determine an element constant by using an optimal approximation for which the kinds of a measurement are a few by expressing a measured value of a 4-terminal parameter of an electric circuit by a rational expression, applying the least squares approximation thereto and determining the element constant. CONSTITUTION:When an initial value of each element constant of an intrinsic element part ZF is given by a prescribed calculation, first of all, a value of an element of a parasitic part is updated. That is, an inclination of an S parameter against element constants Rs, Rg, Rd, Ls, Lg and Ld is calculated by a Newton-Raphson method, and approximation is executed successively so as to minimize an error. Subsequently, an inclination of the S parameter against an intrinsic element part ZF is calculated, and a value of the fundamental element part ZF is updated. It is repeated alternately, and executed until it is converged. In such a way, since a rational expression can be applied, an equivalent circuit constant of every electric circuit element of not only an FET but also a filter, etc., can be derived.

Abstract: PROBLEM TO BE SOLVED: To provide a parallel processor having a correction function for the error of routing information due to the fault of a network by providing a means for decoding reception data and correcting the error, correcting the error of a transfer destination by means of a slice fault and restoring reception data. SOLUTION: The error is detected and corrected in the S8EC-D8ED decoding circuit 121 of a reception interface unit 105-n. The detection/correction parts of the error are informed to an error log circuit 124 through a signal line 264. The error log circuit 124 records the detection/correction parts of the error. When the errors for double slices are detected, the error log circuit 124 informs a console 160 of it through a signal line 204-n and system-down occurs. Data corrected in the S8ECD8ED decoding circuit 121 is transferred to the processor 150-n through a signal line 263. Thus, the correction function can be realized on the error of routing information due to the fault of the network.
