摘要:
A semiconductor pressure sensor comprises a silicon support substrate (1), an insulating layer (2) formed on the silicon support substrate (1), and a silicon thin plate (3) formed on the insulating layer (2). A through-hole (1a) extending in the thickness direction of the silicon support substrate (1) is formed in the silicon support substrate (1). The silicon thin plate (3) located on an extension of the through-hole (1a) functions as a diaphragm (23) that is deformed by an external pressure. The insulating layer (2) remains over the entire lower surface of the diaphragm (23). The thickness of the insulating layer (2) decreases from the peripheral portion toward the central portion of the diaphragm (23). This provides the semiconductor pressure sensor capable of reducing both the offset voltage and the variation of output voltage caused by the variation of temperature and its fabrication method.

A hybrid system control apparatus is provided in which an intercooler (15) is disposed upstream of the motor cooling radiator (70) in a flow path of the ambient air flowing in an engine compartment, and/or is disposed such that at least a portion of the intercooler and a portion of the motor cooling radiator contact each other. The hybrid system control apparatus includes a warm-up portion (60) that increases temperature of the boost air by controlling a load of the engine in cold start of a hybrid system (1) such that the boost pressure from the forced air induction device is equal to or higher than a target boost pressure.

A control apparatus for an internal combustion engine includes an exhaust gas recirculation unit; an intercooler that is provided in the intake passage, at a position downstream of a position to which the exhaust gas is recirculated back; a bypass passage through which an intake air flow bypasses the intercooler. When it is determined that the pH of the condensed water obtained from the exhaust gas is at the level at which the intercooler corrodes in the state where the exhaust gas is recirculated back by the exhaust gas recirculation unit, the control apparatus executes a control for cutting off an intake air flow toward the intercooler to direct the intake air flow only to the bypass passage. Thus, it is possible to ensure reliability of the intercooler.

An exhaust gas recirculation system includes a high-pressure EGR unit; a low-pressure EGR unit; a high-pressure EGR valve; a low-pressure EGR valve; and an EGR control unit that adjusts the opening amount of the high-pressure EGR valve to a required value for achieving the target EGR rate based on the characteristics of the exhaust gas in the low-pressure EGR passage before the operation mode is changed, and that maintains the required value during a period from when the operation mode is changed until when the low-pressure EGR gas is changed to the exhaust gas discharged from the internal combustion engine in the post-change operation mode.

摘要:
A thermo-sensitive flow rate sensor that comprises a plate-like substrate, a part of which is removed so that a space is provided therein, a diaphragm portion formed like a thin layer above the space in such a manner as to be integral with the plate-like substrate, and a heating element constituted by a thermo-sensitive electrically resistant film formed on the diaphragm. Plural holes penetrating the diaphragm portion are bored in an outer peripheral portion of the heating element. Each of the plurality of holes is shaped in such a way as to have obtuse corner portions or to have substantially no corner portions. The thermo-sensitive flow rate sensor measures the flow rate of a fluid, which is to be measured, according to an amount of heat transferred to the fluid from a part heated by energizing the heating element.

A flow rate detecting element measuring the flow rates of various fluids, particularly the intake air of an internal combustion engine. The flow rate detecting element has a thin film layer including a support film and a protective film on one surface of a flat substrate, a heating resistance section and a comparative resistance section thermosensitive resistor having patterns and located between the support film and the protective film. The flat substrate has a recess which penetrates the flat substrate in the thickness direction thereof and facing the heating resistance section and the comparative resistance section. A fluid flow passage communicates with the recess which faces the comparative resistance section for fluid flow into the recess. Flow rate or velocity of a fluid can be measured accurately using the heating resistance section according to the fluid temperature reported by the comparative resistance section.
摘要:
The invented process for producing a polyester supplies a crotonaldehyde with a purity of 95% by weight or more to a reaction system in the reaction of ketene with crotonaldehyde. In this process, unreacted crotonaldehyde may be recovered from a reaction mixture obtained by the reaction of ketene with crotonaldehyde and may be recycled to the reaction system. The &agr;vinylcrotonaldehyde content of the crotonaldehyde to be supplied to the reaction system is, for example, less than 0.5% by weight, and the paraldehyde content of the crotonaldehyde to be supplied to the reaction system is, for example, less than 5% by weight. By decomposing the above-prepared polyester with, for example, hydrochloric acid, a sorbic acid having a satisfactory hue can be efficiently obtained.
