  • Patent number: 11193067
    Abstract: According to the present invention, a liquid crystal aligning agent is configured to contain a polymer [P] which has a partial structure represented by formula (1) and comprises a photo-alignment group. In formula (1), each of R1 and R2 independently represents a hydrogen atom, a halogen atom or a monovalent organic group having one or more carbon atoms; and each of X1 and X2 independently represents —OH, —NH2 or a monovalent organic group having one or more carbon atoms, provided that at least one of X1 and X2 represents “—OR3” or “—NR3R4” (wherein each of R3 and R4 independently represents a hydrogen atom or a monovalent organic group having one or more carbon atoms).

  • Patent number: 8973975
    Abstract: A structure for the front portion of a vehicle body includes both an under load path member and a front load transmission member. The under load path member is extended toward the rear of the vehicle body from a lower bulk member to a sub-frame. The front load transmission member is provided at a position closer to the front of the vehicle body than the under load path member and closer to the rear of the vehicle body than the front end of the bottom of the lower bulk member, and transmits to the under load path member a load which is inputted from in front of the vehicle body. A gap is formed between the front load transmission member and the under load path member.

  • Publication number: 20040113744
    Abstract: Conventional single-piece molded-type inductors are made by pressure-molding magnetic particles of ferroalloy, and have a problem that their insulation resistance drops sharply when placed in a high-temperature environment. Complex magnetic powder is obtained by mixing ferrous crystalline alloy magnetic powder with ferrous amorphous alloy magnetic powder, a connecting agent of 1 wt % to 10 wt % of the mixed magnetic powder being additionally mixed therein, producing a complex magnetic material for use in electronic components. Furthermore, a core is pressure-molded from the complex magnetic material, and a coil is buried in the core to obtain a magnetic element, such as an inductor.

  • Patent number: 5088071
    Abstract: A time switch turns on and off electric equipment connected to the switch. An on time at which the electric equipment is turned on and an off time at which the equipment is turned off are set through a time setting unit. Both the on time and the off time are displayed on a display unit.
