Title: Thin-metalic-film type magnetic recording medium and manufacture thereof
Inventor: KUNIEDA TOSHIAKI
IPC: C22C19/07
Filed: 1980-07-02
Abstract: PURPOSE:To obtain thin-film type magnetic media having excellent magnetic characteristics and corrosion resistance by adding Cr to a magnetic layer of Co or Co-Ni. CONSTITUTION:Evaporation is performed on a glass or polyimide film, with Co or Co-Mi wherein weight % of Ni is 55 or less as a parent material. Said parent material is relatively easy to give magnetic resistant proterty. At this time, the ratio of inclusion of Cr with respect to Co+Cr or Co+Ni+Cr is 2-15wet%. If said material is added, a magnetic film having excellent magnetic prorperty and corrosion resi stance can be obtained. The composition of Cr and the partial pressure of oxygen in the residual evaporation gas greatly affects the characteristics of the magnetic films. In the case the amount of Cr addition lies in the range of 2-15wt% the magnetic resistant force Hc largely increases. If the partial pressure of oxygen exceeds 10<-4> Torr, Hc decreases rapidly, and the effect of Cr addition is lost.

Abstract: PURPOSE:To enable to provide fire resistance and, at the same time, aim not to have poisonous gas of halogen nature generated by having a fixed amount of inorganic flame retardant and barium contained in polyolefine. CONSTITUTION:Aluminium hydroxide, magnesium hydroxide, etc., are named as inorganic flame retardants. The content of said inorganic flame retardant should stay in a range from 50 to 500 weight parts to 100 weight parts of polyolefine. In the range of less than 50 weight parts, the aimed fire-resistance cannot be obtained, and in the range of more than 300 weight parts, the processability falls considerably and extrusion molding becomes difficult. The content of barium used in combination with the inorganic frame retardant should be more than 0.5 weight parts to 100 weight parts of polyolefine. In the range of less than 0.5 weight parts, the drip in burning can not be prevented, resulting in an insufficient fire-resistance. The fire resistance is thus obtained, and, moreover, poisonous halogen gas can not be generated in burning.

Title: Circulator for hot water branch pipe in centralized hot water supply system
Inventor: MURANAKA TAKEMI
IPC: F24D17/00
Filed: 1990-04-06
Abstract: PURPOSE:To measure correctly hot water consumption volume by a method wherein a heat exchanger consisting of a hot water supplying room and its inlet and outlet is connected to a branch pipe so that hot water within the branch pipe is circulated by a circulation pump though the heat exchanger in the downstream of a water meter. CONSTITUTION:When hot water discharging means 8 and 8' are opened, hot water in a going pipe 1 is discharged by the means 8 and 8' through a stop valve 5, a water meter 6 and a check valve 7. At this time, the water meter 6 only measures hot water consumption volume discharged through the means 8 and 8'. When water supply is not through the means 8 and 8', hot water in a hot water storing room of a heat exchanger 19 is circulated by a circulation pump 28 through a bypass pipe 27, the going branch pipe 3 and a return branch pipe 4 and returned to the hot water storing room. This circulation is continued thereafter. In this constitution, as the circulation through branch pipes is carried out in the downstream of the water meter 6 and therefore circulation volume is not measured by the water meter 6 as consumption volume, no measurement difference occurs.

Title: Adaptive array antenna system
Inventor: SEKIZAWA SHINYA
IPC: H01Q3/26
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To separate and suppress a delay wave and an interference wave coming from the same direction as a desired wave by inputting the received signals of plural array antennas arranged spatially apart and suppressing the unwanted waves. SOLUTION: Antenna array parts 1 and 2 of an adaptive array antenna at a base station 4 are installed while being sufficiently spatially separated. When a mobile station 3 transmits a radio wave through a non-directional antenna, the radio wave comes through plural routes, which are affected by surrounding buildings or grounds, to the base station 4. Since a delay wave 3 comes to the array part 1 in the same direction as the desired wave, the desired wave and the delay wave 3 can not be separated only by the array part 1, and the delay wave 3 can not be suppressed.  However, at the antenna array part 2 installed while being sufficiently spatially separated from the array part 1, the waves come while making their angles respectively different in comparison with the array part 1, the probability for the interference wave and delay wave to come from the same direction is decreased at the array part 2, and possibility to suppress the delay wave is improved.
