  • Inverter and control system
    Patent number: 11323057
    Abstract: The present invention reduces electric power consumption of a network inverter. The inverter (1a, 1b, 1c) includes: an MPU (20a, 20b, 20c); and a power supply (10) configured to carry out electric power delivery to the MPU (20a, 20b, 20c) and to a power source circuit (40). In a case where the inverter (1a, 1b, 1c) is to enter a standby state, an electric power delivery control circuit (22) of the MPU (20a, 20b, 20c) blocks electric power delivery to the power source circuit (40).

  • Vehicle seat
    Patent number: 6102481
    Abstract: Vehicle seats are constructed with a seat cushion for supporting the lower body of a passenger and a seat back for supporting the upper body of the passenger. A side holder portion, which is filled with foam material for supporting said passenger at side portions of the upper body, is combined with a backrest portion, which also is filled with foam material for supporting said passenger on the back, such that said side holder portion is integrally and continuously formed with said backrest portion. An opening portion preferably is formed in each of the side holder portions such that said opening portion provides a hole in said side holder portion.
