Title: Digital-analog conversion device
Inventor: HAMAGUCHI NOBORU
IPC: H03M1/70
Filed: 1987-04-28
Abstract: PURPOSE:To sufficiently secure the dynamic range of an output even when a power source voltage is low, by using the same signal as a clock signal being used in a D/A converter as the signal to control a charge pump circuit. CONSTITUTION:When a control signal 12 is set at an H, a transistor Tr T-1 is turned on, and charges a capacitor 14, and when it is set an L, a Tr T-2 is turned on, and the driving terminal of the capacitor 14 goes to the same potential as that of a negative power source 6. At this time, the terminal on the diode side of the capacitor 14 goes to the potential lower than that of the negative power source 6 further, and becomes the output voltage of a negative power source 10 expanded through a diode 16. On the output voltage of the expanded negative power source 10 of the charge pump circuit 9, a ripple synchronized with the signal 12 of the circuit 9 is put. However, since the signal 12 and the clock signal 11 of the D/A converter are set equal, the ripple of the output voltage 10 of the negative power source 10 is synchronized with the clock signal 11. Therefore, the analog signal 8 of the D/A converter becomes the output with a low level of distortion without being affected by the ripple of the expanded negative power source 10 of the circuit 9.

Title: Antiskid device for vehicle
Inventor: ARIKAWA TETSUO
IPC: B60T8/32
Filed: 1981-07-06
Abstract: PURPOSE:To aim at miniaturizing an antiskid device for the furtherance of lightness as well as reducing watt consumption, by causing a double-acting pressure pump to be driven by a hydraulic pressure source only in time of antiskid controlling by means of a detection output which detects whether the antiskid control is under way or not. CONSTITUTION:Compressed fluid in brake cylinders 10 and 11 is discharged to a reservoir 18 by a hydraulic control valve 5. A hydraulic pump 21 pressurizes the fluid of the reservoir 18 and returns it into a master cylinder 1. The hydraulic pump 21 is driven by an oil hydraulic pump 25 of a power steering unit 24 and operates in motion via a solenoid valve 36. A control unit 16 operates the solenoid valve 36 only in time of antiskid controlling so that any solenoid pump required for double-acting pressure is no longer serviceable; the antiskid device can be thus miniaturized for the furtherance of lightness.

Abstract: PROBLEM TO BE SOLVED: To enhance the heat reserving property and fire-preventive performance of a building by housing, in walls, a ceiling, etc., of the building, a water bag for sealing water in a thin film thereof, the thin film having properties of being broken by thermal melting, thermal decomposition, or the like in a predetermined range of temperature, in addition to waterproof. SOLUTION: A water bag 8 is obtained by sealing water in a thin film thereof which has properties of thermal melting and thermal decomposition in a temperature range of 100 deg.C or more to 300 deg.C or less, in addition to waterproof, and the bags are housed in spaces 7a, 7b, defined by frames 2, 4, 5 and 3, 4, 5, respectively, which constitute a building. A melting point or a decomposition temperature lower limit of a material forming the thin film is set higher than an upper limit of temperature which can be reached in daily life. When the water bag 8 is set near a roof which is irradiated by direct sunlight over a long period of time, a material whose melting point or decomposition temperature exceeds 100 deg.C should be employed.  When a fire breaks out and heat is applied, the thin film of the water bag 8 is melted or decomposed, and therefor, water therein is discharged for extinguishing fire or preventing fire spread. Further, water has a large specific heat, and therefore the wall housing the water bag 8 can stably maintain the temperature in the building relative to fluctuation in outside temperature. In addition, construction of a fire-preventive structure employing the water bag is easy, leading to a shortened construction period.

Title: Sputtering method for magnetic head
Inventor: KIKUCHI YOSHIMI
IPC: C23C14/54
Filed: 1987-05-01
Abstract: PURPOSE:To realize an annealing process in which the maximum permeability and a proper resistivity are set in the optimum ranges, by applying feedback control on a sputtering condition by monitoring the flection of a magnetic head substrate, and giving prescribed compressive stress on a thin film. CONSTITUTION:The magnetic thin film of ferromagnetic metal is formed on the magnetic head substrate 1A or 1B by using a sputtering method. At this time, the internal stress of the thin film is monitored by using a strain gauge 2 so as to remain the prescribed compressive stress on the thin film, and the feedback control is applied on the sputtering condition. The substrates 1A and 1B show the flection decided by the shape of the substrate, an elastic coefficient, and stress in the thin film, therefore, it is possible to measure the internal stress by a wire strain gauge whose resistance value changes according to the magnitude of distortion. In such a way, it is possible to reduce the remaining stress of the thin film by the annealing process, and to set the maximum permeability and the proper resistivity in the optimum ranges.
