Title: D/a conversion device
Inventor: TANIMOTO SUSUMU
IPC: H03M1/68
Filed: 1990-02-09
Abstract: PURPOSE:To prevent the inuniformity of stress against diffusion resistance resulting from the uneven arrangement of elements and generated at the time of resin molding by arranging a p-channel MOSFET or an n-channel MOSFET of a dummy element at a proper place so that the arrangement of the elements becomes uniform. CONSTITUTION:Each terminal (d) to (f) of a CMOS switch corresponds to terminals (d) to (f). Reference voltage is the supply voltage VDD of the integrated circuit. The n-channel MOSFET of a switch array close to the supply VDD becomes a dummy, and besides, the p-channel MOSFET of the switch array close to a grounding point becomes the dummy. By arranging the dummy element in this way so as to make all switches into the CMOS switches, a layout pattern on the integrated circuit becomes a uniform pattern.

Abstract: PURPOSE:To detect the leakage of Na over the wide range of density with high sensitivity and accuracy by a method wherein a heat generator is used as an ionization electrode to detect the change of an ion current and a value of the heat generator resistance in an Na detector of the sampling type. CONSTITUTION:A sintered heat generator (ionization electrode) 3 prepared by sintering molybudenum silicide, silundum and the like, and an ion collector electrode 4 are arranged in the container of a detector 2 so that the generator and electrode face each other. A pump 9 is operated to lead sampling gas to the container 2 from a pipe 1 to allow Na contained in the gas to touch the heat generator heated to have a high temperature by a heating supply 5. The ionized Na is caught by the ion collector electrode, or cathode, when a detector 8 detects the ion current generated to make clear the leakage of Na (a trace). On the other hand, when Na in the sampling gas shows high density, Na attached to the surface of the heat generator 3 and its resistance is reduced. Then the increased current value obtained at that time is subtracted by the detector 6 in order to detect the leakage of Na (greater volume).

Title: Production of head cleaning tape
Inventor: ISOYAMA NOBUKAZU
IPC: G11B15/00
Filed: 1985-02-20
Abstract: PURPOSE:To reduce the effect of a magnetic head even in case the head is driven repetitively with a magnetic recording/reproducing device, by forming intermittently the films with a material having the cleaning function on the magnetic surface of a magnetic recording medium and therefore eliminating a joint part between a checking tape and a cleaning tape. CONSTITUTION:A coating material is applied intermittently to a checking tape 6 by the up-down movement of a roll 7. The tape 6 contains a magnetic layer and can record and reproduce signals. A roll 8 carries the coating material from a supply part 10 by its revolutions. A knife 9 functions to control the coating material carried on the roll 8 to a fixed amount. Then the tape 6 is driven and at the same time the roll 7 is moved up and down repetitively and synchronously with the drive of the tape 6 to apply the material having a cleaning function to the tape 6 at a fixed interval. Then the tape 6 undergoes the drying and other processes and is slitted finally. Thus a desired cleaning tape 5 is obtained with application of a material having the cleaning function. Thus it is possible to obtain both checking and cleaning functions with a single tape with no joint produced between both tapes.
