IPC: B41J2/345
Filed: 1989-09-07
Abstract: PURPOSE:To reduce density nonuniformity at the time of printing to a level where there is no problem in practical use by a method wherein by reducing drastically the resistance of a lead wire from the common connecting end of a FET for switching to earth, the resistance value difference up to earth is reduced, and difference in applied voltage to a heating body in accordance with the location of the heating body is made smaller. CONSTITUTION:An earthing terminal is also provided on the way of a common connecting wire of a FET for switching, and earthing terminals are taken out from the total of 4 spots, and the resistance of a lead wire from the common connecting end of the FET for switching to earth is drastically reduced. At the same time, the resistance value difference from respective heating bodies, which have passed through the FET for switching, to earth is made smaller. Therefore, the influence by equivalent resistance of the lead wire from respective heating bodies 1-1, 1-2,...1-n to the earthing terminal can be reduced, and the applied voltage to respective heating bodies can be held in a designated range which is further narrower. Therefore, the heating quantities of respective heating bodies 1-1, 1-2,...1-n can be made more uniform, and it is possible to reduce density nonuniformity at the time of printing.

Title: Bus arbitration controller
Inventor: KOYAMA HAJIME
IPC: G06F13/36
Filed: 1986-10-01
Abstract: PURPOSE:To evade competition for the use of bus by providing a microprocessor which does not incorporates a function to arbitrate the right to use bus and a direct memory access (DMA) controller with which the right to use bus is acquired/abandoned through a hand shake system of bus-use request signal and bus-use permission signal. CONSTITUTION:In case the microcomputer 1 that does not incorporate a bus arbitration function uses the bus, preliminarily to it, a bus-use request signal outputted from a DMA controller 2 is confirmed, and in case the use of bus is requested, the bus-use permission signal is supplied to the DMA controller 2 and thus the bus is released for the DMA controller 2. On the other hand, if the use of bus is not requested, a signal to permit the microcomputer 1 to use continuously the bus is outputted, and the microcomputer 1 uses the bus. In such a way, the competition for the bus-use between a microcomputer not having the bus arbitration function and a DMA controller can be evaded.

Abstract: PURPOSE:To industrially and readily produce high-purity lithium borate, by stirring calculated amounts of an Li compound and B compound in the presence of water while heating, aging the resultant solution while stirring even after deposition of crystals and filtering and drying the crystals. CONSTITUTION:An Li compound and B compound in calculated amounts based on Li2O and 2B2O3 in the composition formula Li2O.2B2O3.3HO are heated in the presence of water to give a solution.

Title: Apparatas for termination of transmission line
Inventor: FURANKOIZU IBURAAHIIIMU ATARAA
IPC: H04B3/00
Filed: 1988-09-20
Abstract: PURPOSE: To place a connector at a position physically far from a terminating circuit network by supplying an appropriate impedance and a balance through a switching action of a connector. CONSTITUTION: When a shielded pair twisted wire cable 60 is connected between the connector 13 and a terminating circuit and a cable 12 is terminated in a pair twisted wire mode, a resistor 26 becomes parallel to the resistors 28 and 30 and the entire impedance of parallel connection with the single coil side impedance of a transformer 36 is 150 ohms. At the time of operating the cable 12 in a coaxial mode, a switch 20 short-circuits a port 18 to the case of the connector 13 and connects it through the port 19 to the shield of the cable 60, the resistor 26 becomes parallel to the resistor 28 and the terminating impedance of 93 ohms is generated. Thus, since the appropriate impedance and balance are similarly supplied in any mode, the connector 13 can be placed at the position away from the terminating circuit network.

Title: Liquid crystal display body
Inventor: HAYAKAWA MOTOMU
IPC: G02F1/1365
Filed: 1984-11-06
Abstract: PURPOSE:To improve the yield of production by using a resin of spherical body for an object which is to be sprayed to the liquid crystal layer side of a substrate and has a specified size. CONSTITUTION:The figure illustrates the state in which the resin 11 of spherical body consisting of divinyl benzene and styrene is sprayed as a gap material to the surface of the substrate for which a non-linear element consisting of the three-layered thin-film structural bodies; metal-insulating body-metal (hereinunder expressed as MIM). The contact part between the gap part and the substrates when the gap material is held in place in a sandwich state between two sheet of the substrates is a point with the resin of spherical body and is a line with a cylindrical glass fiber. The resin 11 has therefore the lower contact probability with the MIM element. The degree of freedom exists in all directions. The resin 11 is softer and more elastic than the quartz glass fibers and therefore even if said resin contacts with the MIM element and is brought into press contact with two sheets of the substrates by said substrates, the MIM element is made less destructable in spite of the mechanical pressure exerted to the MIM element.
