Title: Vehicular automatic transmission with abnormality detection device and abnormality detection method therefor
Inventor: KURIHARA HIROYUKI
IPC: F16H61/28
Filed: 1995-03-03
Abstract: PURPOSE: To improve the durability of a transmission as well as the reliability thereof by providing a backup solenoid valve drive control section for making judgement as to whether or not an abnormality is attributable to an electrical system failure, on the basis of voltage applied to a solenoid valve, when the valve identifies the existence of an error, and selecting a solenoid valve group system for use. CONSTITUTION: A plurality of solenoid valves are formed out of the first and second system solenoid valve groups, and a control means selects one of the groups for use. An abnormality detection device 31 detects a gear change status via a gear change detection means 36 and an abnormality judgement means 32 makes judgement about the abnormality of the solenoid valves, on the basis of information from the means 36 and the comparison of control instruction signals to the solenoid valves. Also, a failure cause judgement means 34 makes judgement as to whether the abnormality is attributable to an electrical system failure, based on voltage applied to each terminal of the solenoid valves, when the means 32 identifies the abnormalitiy.  When the failure cause of the solenoid valves is identified, a backup solenoid valve drive control section 35 selects and backs up the system of the solenoid valve groups. Thus, the durability of a transmission as well as the reliability thereof can be improved.

Title: Lead storage battery
Inventor: SAITO SHINJI
IPC: H01M4/68
Filed: 1987-02-27
Abstract: PURPOSE:To improve the overdischarge leaving property by using electrode plate base bodies which consist of a Pb-Ca-Sn alloy and either a Pb-Ca alloy or a Pb-Ca-Sn-Sb-Al alloy, while an alkaline earth metal ion is present in the electrolyte. CONSTITUTION:When CaSn2 or PbxCaySnz which is an intermetal compound is produced in a Pb matrix, and an electrode base body is anode-oxidized, it is considered that such a product is scattered in the oxide membrane to maintain the conductivity, or the Sn is oxidized to produce a compound such as SnO or SnO2 to improve the charging property because such a compound is semiconductive. The Sb has a function to suppress the rise of the inner resistance when the battery is being left in an overdischarge condition. Furthermore, where Al is present, the Ca is prevented from making a dross but fixed in the alloy, and the addition of Al is effective. On the other hand, as an additive to the electrolyte, an alkaline earth metal is considered to be preferable, in consideration of the influence to the other properties (cycle life and capacity) of the battery. In such a composition, the overdischarge leaving property can be improved.

Title: Arc start method of direct current tig welding machine
Inventor: HAGIWARA SEIGO
IPC: B23K9/067
Filed: 1979-04-13
Abstract: PURPOSE: To make the starting characteristic and stability of arc consistent and make arc starting method economical by making the drooping resistance small at the arc starting and changing over the drooping resistance to large after the arc generation.  
     CONSTITUTION: Until an arc generation detecting relay actuates to open its normally closed contacts 4, the drooping resistance is only 3 but when the relay actuates to open its normally closed contacts 4, the drooping resistance (superposed resistance) becomes 3 added with 3'. Hence, by flowing the large superposed current at the arc starting, the shifting from high-frequency discharge (cold cathode discharge) to arc discharge (hot cathode discharge) may be made smooth. On the other hand, by changing over the superposed current to smaller one after the arc starting, the main arc may be stabilized and the arc break-off may be prevented.
