Title: Direct-current electric power device
Inventor: SUZUKI KAZUYA
IPC: H02M3/00
Filed: 1980-05-14
Abstract: PURPOSE:To improve functions of a low-output voltage protecting circuit by providing as a switch a transistor controlled by an output voltage between a voltage detection point and a detection terminal. CONSTITUTION:Since a load current is supplied to a transistor 11 as far as a load voltage is normal, a current is flowed through a resistance R2 to cause a voltage drop, but the voltage of a reference power source 9 is lower, so that a low-output voltage protecting circuit 8 will not supply a signal to a power circuit 2. Once the load voltage drops, the transistor 11 turns off, so a voltage drop across the resistance R2 decreases to make the voltage of the reference power source 9 higher, so that the low-output voltage protecting circuit 8 supplies the signal to the power circuit 2.

Abstract: PURPOSE:To modulate effectively light with optional polarization characteristics, to reduce power consumption, and to make a fast response by providing an electric field impressing means which controls the orientation of liquid crystal charged between substrates at least either of which has a scattering surface. CONSTITUTION:While no electric field is impressed between transparent electrodes 2, i.e. in a stationary state (electric field unimpressed part Y), the liquid crystal 4 is oriented at random the difference in refractive index between a transparent material having the scattering surface 3 and the liquid crystal 4 is random on their interface, so that incident light 5 is scattered by the layer consisting of the scattering surface 3 and liquid crystal 4. While an electric field is impressed between the electrodes 2 (electric field impressed part X), on the other hand, the liquid crystal 4 is oriented in the direction of the electric field and the orientation direction of the liquid crystal 4 coincides with the traveling direction of the light 5 and the liquid crystal 4 has a constant refractive index to the light regardless of the polarization characteristics. In this case, the refractive index of the material having the surface 3 and the constant refractive index of the liquid crystal 4 are equalized to each other and then the light 5 is transmitted without being scattered. Thus, the scattering and transmission of the light 5 are controlled according to whether the electric field is applied or not.

Abstract: PURPOSE:To provide a method for manufacturing a disc for an information recording medium which is free from deterioration in the characteristics despite long-term reproduction by dipping the disc for the information recording medium into a lubricating oil or a soln. of the lubricating in an org. solvent oil to impregnate the lubricating oil therein thereby forming the always satisfactory lubricating oil layer on the surface. CONSTITUTION:A base material of a disc for an information recording medium consists esentially of PVC resin incorporated therein with a required amt. of fine particles of a conductive material. Said material is immersed in a lubricating oil or a soln. of the lubricating oil in an org. solvent. For example, methyl chlorophenylsiloxane is used for the lubricating oil and, for example, n-heptane is used as the org. solvent to dissolve the lubricating oil. When the disc for the information recording medium is dipped in the soln. of the lubricating oil in org. solvent, the lubricating oil is impregnated into the gaps among the molecules in the PVC resin which is the base material for the disc by the inter-molecular attraction between the lubricating oil and the molecules of the PVC resin. The disc subjected to the impregnation of the lubricating oil is removed from the soln. and thereafter the disc is rotated at a high speed to form the thin film of the lubricating oil on the surface to a required thickness, for example, <=500Angstrom .
