Title: Detecting apparatus for leak oil of oil-filled electric apparatus
Inventor: ABE YOICHIRO
IPC: G01M3/02
Filed: 1988-06-20
Abstract: PURPOSE:To detect a minute quantity of leak oil rapidly and highly precisely by a construction wherein an oil quantity adjusting tank wherein an incombustible insulating oil is sealed up hermetically without pressure is surrounded by a cover element to form a trapping chamber and a halocarbon-type solvent sensor is provided in the vicinity of the bottom part of this chamber. CONSTITUTION:A trapping chamber 22 for a leak oil or a vaporized gas thereof is formed by a cover element 21 surrounding the whole or a part of an oil quantity adjusting tank 4, and a halocarbon-type solvent concentration sensor 24 of a semiconductor type, for instance, is provided in the vicinity of the bottom part of said trapping chamber 22. When leak of the oil occurs in the oil quantity adjusting tank 4, the vaporized gas whose specific gravity is larger than that of air stays in the vicinity of the bottom part of the trapping chamber 22, and the solvent concentration sensor 24 detect this vaporized gas and delivers a signal. By driving an alarm 26 according to this signal, therefore, the occurrence of the leak of the oil can be known in an early stage.

Title: Speed change control device for automatic transmission
Inventor: OTSUBO HIDEAKI
IPC: F16H59/46
Filed: 1988-06-20
Abstract: PURPOSE:To prevent a rapid change of output torque by feedback-controlling an engaging transient pressure of oil first in execution of speed change and suspending a feedback control, when a transmission reaches the final period of speed change, thereafter controlling the engaging transient pressure of oil by a predetermined map. CONSTITUTION:When an automatic transmission engages its friction engaging unit, an engaging transient oil pressure control means inputs a rotary speed of a member of the friction engaging unit, changing the rotary speed by speed change execution, with an engine speed detected by an actual speed detecting means, and an engaging transient oil pressure is feedback-controlled in a manner wherein the member rotary speed is generated along a locus of the target rotary speed set by a decision means. Next, when a speed change final period detecting means detects a speed change to be placed in the final period, a feedback control is suspended, while the engaging transient oil pressure of the speed change final period is anticipation-controlled being based on a predetermined map. Thus surely reducing the oil pressure further in the speed change final period while feedback-controlling the engaging oil pressure, a speed change shock can be always decreased.

Title: Flow rate limiting body for limited current type oxygen sensor and manufacture thereof
Inventor: HIRANO YUJI
IPC: G01N27/41
Filed: 1996-06-13
Abstract: PROBLEM TO BE SOLVED: To provide a flow rate limiting body with which high measurement precision and along sensor life of a limited current type oxygen sensor can be obtained, and a manufacturing method for the body. SOLUTION: A flow rate limiting body is made of a porous alumina substrate 10 having 0.002-0.5μm average micropore diameter and 0.05-2.0ml.mm/atm.min.cm<2> gas permeability. Consequently, since the average micropore diameter is sufficiently small, of all gases, the oxygen gas diffusion coefficient scarcely depends on the pressure at a normal working pressure range, for example, 0.8-1.2atm. As a result, the quantity of oxygen gas which is introduced into a closed space 34 (that is, one face of a solid electrolytic substance 18 on which one of a pair of electrodes 16a, 16b is formed) after passed through the porous alumina substrate 10 is made approximately proportional to the pressure of the objective gas to be measured. Meanwhile, since the gas permeability is made sufficiently low, the quantity of oxygen gas to be introduced into the closed space 34 after passed through the porous alumina substrate 10 is made sufficiently low and even in the case the oxygen concentration in the objective gas to be measured is high, the increase of permeated oxygen gas is relatively low.

Abstract: PURPOSE:To enhance the reliability of a groove capacity insulating film by a method wherein, after forming a groove perpendicular to the surface of a silicon substrate, an oxide film or a nitride film is formed on the groove and the silicon substrate while the edge parts of the groove are rounded by an etching process. CONSTITUTION:A groove 12 is formed perpendicular to the surface of a silicon substrate 11 to bond a silicon oxide film 13 onto the whole surface and then the silicon oxide film 13 on the surface of the silicon substrate 11 is removed by an anisotropical etching process to leave a silicon oxide film sidewall 14 inside the groove 12. Next, after isotropically etching away the silicon oxide film sidewall 14 and the surface of the silicon substrate 11 at the same rate, the silicon oxide film sidewall 14 is selectively removed. Through these procedures, the edge parts of the groove 12 are rounded so that the field concentration at the edge parts may be attenuated when a groove capacity is applied to the capacitor of a dynamic memory as well as the thinning phenomenon of the insulating film thickness in the edge parts may be relieved when the capacity insulating film is formed.
