Abstract: PURPOSE:To reduce the size of the shape of a polygon mirror when an image is drawn by using plural pieces of luminous flux for drawing by providing a light source which emits the pieces of luminous flux so that they cross one another, a deflecting means, and a scanning lens. CONSTITUTION:This drawing device is equipped with the light source 10 which emits the three pieces of luminous flux for drawing so that they cross one another, the deflecting means 20 which deflects those pieces of luminous flux and puts in scanning motion right before the three pieces of luminous flux from the light source 10 cross one another, and the scanning lens 30 which converges the pieces of luminous flux from the deflecting means 20 on a drawing surface 41.

IPC: G11B11/105
Filed: 1990-10-24
Abstract: PURPOSE:To facilitate overwrite by a method wherein a sputtering angle is selected to be smaller than 30 deg.. CONSTITUTION:A Tb target T1 and an Fe target T2 are placed in a sputtering apparatus. After a chamber 4 is evacuated to vacuum, a DC power supply 5 is turned on and Ar gas is introduced to start sputtering. Thus an M layer made of Tb27Fe27 is formed on a substrate S. Then, while the vacuum is maintained, the target T2 is replaced by a target T2 (FeCo alloy) and sputtering is performed again. By this sputtering, a W layer made of Tb18Fe74Co8 is formed. Thus an overwritable magneto-optical recording medium can be manufactured. By selecting a sputtering angle to be smaller than 30 deg., the productivity of the manufacture of overwritable recording media can be improved.

Abstract: PURPOSE:To improve chipping resistance and corrosion resistance by using topcoating based on a composition prepared by compounding a cursing agent with a resin containing a hydroxysilane group and/or a hydrolytic group directly bonded to a silicon atom and an epoxy group as essential functional groups. CONSTITUTION:Cationic electrodeposition paint is applied to a steel plate and, subsequently, barrier coat based on a modified polyolefinic resin forming a film having static glass transition temp. of -30 to -60 deg. is applied to the coating surface thereof.

IPC: H02J7/02
Filed: 1991-10-31
Abstract: PURPOSE:To facilitate parallel connection of a number of batteries by a method wherein, when the batteries are charged, switching circuits which are connected in series to the respective batteries are successively controlled cyclically and, if one battery is fully charged, the switching circuit connected to the battery is kept in an open state and the switching control is shifted to the next switching circuit. CONSTITUTION:A shift register 8 controls switching operations of switching circuits S in accordance with the clock period of a clock circuit 9. A voltage detector 5 detects the voltage of an individual battery 2-n which is selected by the shift register 8. A comparator 7 sets a reference voltage VREF as a charge completion voltage and, when the voltage of the battery 2-n which is selected by the shift register 8 reaches a voltage higher than the reference voltage, operates a clock changeover switch 11 to change a reference clock from SLOW to FAST and reduce a closing time. When the terminal voltages of all the batteries are elevated and the reference clock is changed to FAST continuously, the shift register 8 stops its operation and the charging operation is completed.

Abstract: PURPOSE:To cool a machine chamber in which apparatuses of a communication system cooled by a natural convection of room temperature and apparatuses of an information processing system cooled forcibly by air discharged from the air conditioner, are mixed and installed, by simultaneously controlling room temperature, discharged temperature and humidity. CONSTITUTION:The method of controlling the air conditioner controlling the room temperature, the discharge air temperature and humidity is to control the rotational speeds of a compressor 1 and a blower 11 for drawing the measured values near to set values in a case where the measured room temperature is higher or lower than the set temperature, in a case where the measured room temperature is higher or lower than the set temperature, in a case where the measured discharge temperature is higher or lower than the set discharge temperature, or in a case where the measured humidity is higher than the upper limit value of the set humidity or lower than the lower limit value of the set humidity. For example, in a case where the measured room temperature is higher than the upper limit value of the set room temperature and the measured humidity is higher than the upper limit value of the set humidity, the rotational speed of the compressor 1 is increased. In a case where the measured room temperature is higher than the set room temperature and the measured discharged temperature is lower than the set discharge temperature the rotational speed of the flower 11 is increased. When the method of operating the compressor 1 is the same as that of operating the blower 11, the control based on either of both methods is ignored.
