Title: Power-supply changeover circuit for uninterruptible power-supply apparatus
Inventor: TOYODA MASASHI
IPC: H02J9/06
Filed: 1994-07-28
Abstract: PURPOSE:To provide a power-supply changeover circuit, for an uninterruptible power- supply apparatus, which can sufficiently prevent a semiconductor switch from being damaged even when an overcurrent is changed over due to the short circuit of a load or the like without using a semiconductor switch whose overcurrent-resistant amount is large. CONSTITUTION:A power-supply changeover circuit is related to a power-supply changeover circuit, for an uninterruptible power-supply apparatus, in which, when a power- supply changeover switch 2 changes over the supply of electric power to a load 4 to a bypass AC power supply B from the uninterruptible power-supply apparatus A composed of an inverter 1, the load 4 is first connected to the bypass AC power supply B by means of a semiconductor switch 3. Consequently, the semiconductor switch 3 is constituted of GTO thyristors 3A, 3B which can be cut off forcibly. When a load current 1 becomes excessive, the GTO thyristors 3A, 3B which have been turned on once are cut off forcibly before the power-supply changeover switch 2 is changed over to the B side. Consequently, without using a semiconductor switch whose overcurrent-resistance amount is large, it is possible to surely prevent the semiconductor switch from being damaged. As a result, the power-supply changeover circuit can be miniaturized, and it can be made sufficiently low-cost.

Abstract: PURPOSE:To ensure a prescribed gearshift by allowing the steering lever to move by a certain amount with the hydraulic oil which is sent from the sensor cylinder working with the essential turn operation, and storing the excessive oil in the excessive oil chamber tentatively. CONSTITUTION:An essential turn operation is sensed by the sensor cylinder 103 and the cylinder sends the hydraulic oil in an amount corresponding to the turning. While a certain amount of the oil is sent at the initial stage, the hydraulic cylinder 54 works to move the steering lever 51 by a certain amount. When the lever comes to the stroke end and the inner pressure rises, the excessive oil chamber opens and connects to the oil chamber of the cylinder to store the excessive oil sent by the sensor cylinder tentatively. When the sensor cylinder comes not to work, the hydraulic oil is sent back from the excessive oil chamber contracting by the elastic force.

Title: Heat resistant aluminum alloy for casting
Inventor: ADACHI MITSURU
IPC: C22C21/02
Filed: 1983-09-26
Abstract: PURPOSE:To obtain the titled alloy contg. no Ni, undergoing a small extent of permanent deformation, and having superior strength at high temp., superior flowability, machinability and a low coefft. of thermal expansion by increasing the large amount of Mg in an Al-Si-Cu-Mg alloy. CONSTITUTION:The titled alloy for heat resistant machine parts, especially the piston of an engine for a vehicle consists of, by weight, 8-14% Si, 1-4% Cu, 1.5-3.5% Mg and the balance Al. The alloy may further contain 0.02-0.2% Mo and/or 0.02-0.2% W. The eutectic point of Al-Si in the alloy is considerably shifted to the high Si side by adding much Mg while increasing the strength at high temp., so primary crystal Si is hardly produced in spite of the relatively high Si content which is advantageous to reduction in the coefft. of thermal expansion or the improvement of the flowability. Accordingly, the desired high performance is shown.
