Title: Uninterruptible power supply equipment
Inventor: MORIKAWA MASAHITO
IPC: H02J7/00
Filed: 1990-06-19
Abstract: PURPOSE:To prevent the consumption of an unnecessary battery by stopping a DC/DC converter or a DC/AC inverter when load is brought to a preset state or less the service interruption of a commercial power supply. CONSTITUTION:When service interruption is generated, an interruption signal is transmitted instantaneously over a control section (e) from a service interruption detector (g). When the value of output currents obtained from an output current detector (h) reaches an expected value or more at that time, this device is supplied with the energy of a battery (f), and the device continues an output. When output currents acquired from the output current detector (h) reaches the expected value or less, on the other hand, the control section (e) stops the oscillation of the DC/DC converter or the DC/AC inverter. That is, when the load side of the uninterruptible power supply equipment is stopped completely or brought to a standby state and output currents reach the expected value or less, the oscillation of the DC/DC converter or the DC/AC inverter is stopped automatically, thus preventing the consumption of a battery.

IPC: B60C5/08
Filed: 1997-06-18
Abstract: PROBLEM TO BE SOLVED: To effectively prevent the generation of puncture without increasing the manufacturing cost by forming a crescent-shaped profile so as to be gradually gauged down from a thick part of a tube corresponding to a tire side part which has the maximum gauge of thickness, toward both sides of a bead part and a shoulder part.

Abstract: PURPOSE:To control idling revolutions stably with high accuracy by on/off driving solenoid valves at the first and the second pressure introduction passage of a pressure servo motor by means of a pulse signal of a duty corresponding to an opening position deviation. CONSTITUTION:In an idling operation, a computing element 400 makes an integral control action by an output of an idling decider 700 on the basis of a deviation (c) between an actual number of revolutions (a) and a target number of revolutions (b), and sets a target throttle position (e). This position (e) is compared with an actual opening position (d) of a throttle valve 101 by an opening sensor 500, and a pulse width command corresponding to its amount of deviation (f) is generated at every fixed period in the first signal command circuit 601. Thereby, an atmosphere side solenoid valve 208 or a negative pressure side solenoid valve 204 is operated for opening and closing via a pulse signal generating circuit 604, and the opening of the throttle valve 101 is controlled via a negative pressure servo motor 201. This construction promotes the capacity of response for position controlling, and permits to control idling revolutions  stably with high accuracy as preventing hunting.
