Title: Manufacture of magnetic recording medium
Inventor: HAMADA MITSURU
IPC: C09D7/12
Filed: 1979-06-20
Abstract: PURPOSE: To obtain a magnetic recording medium which excels in the surface lubricating properties and the durability, by coating the magnetic coating material containing a specific amount of paraffin to the solid component such as the magnetic powder, the binder or the like and then decomposing and then evaporating the paraffin at the heating and solidifying time.  
     CONSTITUTION: The magnetic coating material, containing the liquid paraffin having 500W600 average molecular weight with 2.5W15wt% to the solid component such as the magnetic powder, the binder or the like, is coated on the supporter of the Al disk, etc. Then it is cured by heating at about 250°C. In that case, the liquid paraffin is decomposed and evaporated to cause the micropores to the magnetic film. The surface of the magnetic film thus obtained is polished up to a fixed thickness of the film to obtain a magnetic recording medium. Then the "Freon" solution of the lubricant such as the perfluoroalkyl polyether or the like is coated on the magnetic film of the recording medium and then undergoes the heat treatment at about 200°C to secure the trapping of the lubricant within the micropores. In this way, a magnetic recording medium having the excellent surface libricating properties and durability is obtained.

Title: Control device for elevator
Inventor: FUJINO ATSUYA
IPC: B66B1/18
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To achieve power saving when an elevator is operated by dispersion and standby operation, by moving an elevator to a standby floor only when a designated standby floor for the elevator to return to a reference floor, to stand by or to disperse, is above the present floor, when the elevator is not required to be used by a user and is operated by the dispersion and standby operation, and by continuing a stoppage at the present floor if it is below the present floor. SOLUTION: When an elevator is not required to be used, if a setting for a standby floor for the purpose of return to a reference floor operation, standby and dispersion operation is checked. When the standby floor is set, conditions to carry out the dispersion and standby operation are satisfied. When the standby floor is above the present floor, since a balance weight 2 is heavier than a car with no user in it, electric power can be collected to a power source 8 from a motor 5 by a power converter 7 by making use of unbalance of the load, in order to save power, and therefore, the elevator is controlled to move to the standby floor. When the waiting floor is below the present floor, since more electric power is required for the movement on the contrary, stoppage at the present floor is continued.

An NMOS 5 is broken down and the fuse 7 is melted by a large current, whereby a contact point between an NMOS 3 and the NMOS 5 is disconnected from the write data line 17. Accordingly, writing is executed. The program signal is turned to 'H', the NMOS 21 is turned ON, and a read word line 9 is turned to 'H', with the NMOS 3 turned ON. When the fuse 7 is not cut, a read data line 13 is kept to be 'H' set before reading is carried out, and data of the 'H' level are read out from the selected memory cell 1.

The control voltage is impressed from an external variable control power source 12 to the varactor diode 10 of the matching circuit 9a and the reactance component is set at a prescribed value. Therefore, the input signal is matched to the input impedance of a mu-wave FET 1 and efficiently inputted to this FET 1. The input signal is amplified and transmitted for the prescribed electric length along lines 40 and 4. For the matching circuit 9b, the reactance component of the varactor element 10 is set by the external variable control power source 12 and the signal is matched to the output impedance of the mu-wave FET 1. Then, the output power of the FET is efficiently taken out from a terminal 8.
