It is an object of the present invention to provide a touch mode capacitive pressure sensor having higher pressure durability than conventional sensors. In this invention, a touch mode capacitive pressure sensor has a diaphragm made from boron-doped silicon, and the boron concentration at the top face of the diaphragm is equal to or greater than 1×1019 cm−3 and less than 9×1019 cm−3. Further, in this invention, a touch mode capacitive pressure sensor has a conductive diaphragm made by doping of an impurity and anisotropic etching, and the etch pit density on the top face of the diaphragm is equal to or less than five per μm2, and preferably equal to or less than one per μm2. As a result, the pressure durability of the diaphragm is greatly improved.

In an image forming apparatus provided with an image transporting belt that holds an image directly or indirectly and is laid on a plurality of tension rolls thereby to move circularly, and a sub-unit having a rotary roll that comes into contact with this image transporting belt and is rotationally driven by a drive section, the drive section includes a drive source, and an elastic drive power transmitting member that transmits drive power from the drive source and absorbs difference in peripheral speed produced between the image transporting belt and the rotary roll. The drive section includes a slip transmission member that engages with the elastic drive power transmitting member and slips under a condition over a peripheral speed difference absorbable range of the elastic drive power transmitting member.

A state determining apparatus for an exhaust gas recirculation system is provided for appropriately determining the state of an exhaust gas recirculation system including an EGR passage. An exhaust gas recirculation system is arranged in an exhaust system of an internal combustion engine including an EGR passage for recirculating a portion of exhaust gases to an intake system in accordance with an operating state of the internal combustion engine. The state determining apparatus comprises a humidity sensor arranged in the EGR passage for detecting a humidity within the EGR passage, and an ECU for determining the state of the exhaust gas recirculation system based on a result detected by the humidity sensor.

A failure determination device that detects the humidity of exhaust gases from an internal combustion engine and a control system for an exhaust passage changeover valve, which can switch the changeover valve with appropriate timing, thereby enabling sufficient purification of exhaust gases. An operating condition of the engine is detected. Based on the detected operating condition of the engine, it is determined whether the engine is in an operating condition in which failure determination of the humidity sensor can be executed. It is determined whether the humidity sensor has failed, based on a result of detection by the humidity sensor, when it has been judged that the failure determination of the humidity sensor can be executed.
摘要:
A fuel injection timing control system for a direct injection spark ignition internal combustion engine which is operated at an ultra-lean burn combustion or at a pre-mixture charged combustion. In the system, a fuel injection start timing limit by which injection of the determined fuel injection amount should be started and a fuel injection end timing limit by which injection of the determined fuel injection amount should be ended are determined based at least on the detected engine speed in accordance with predetermined data so as to avoid smoke from occurring in the engine, and when a determined fuel injection amount can not be injected within a time of period defined by the limits, a desired fuel injection start or end timing or the determined fuel injection amount is corrected, thereby ensuring the engine torque drop to a minimum extent, while surely avoiding smoke to occur.
摘要:
A method or device for computing material requirements which calculates various parts and materials necessary for products to be produced when a production plan is input, in order to reduce the processing time for a material requirements computation. In order to establish the object, the method or device of computing material requirements is provided, which can perform a parallel process without using conventional low level codes. Parts computing means are respectively assigned to items. When the lower parts computing means receives the computation result of the upper parts computing means, it independently executes the computing process if the computation result is sufficient for the parts computation. The process rate of the material requirements computation can be improved by performing the load distribution under a fixed rule, including that to which computer the data of an item is loaded or by which computer an item is processed, when the material requirements are computed in parallel process using plural computers.

Transgenic mice carrying a recombinant DNA construct comprising the gene encoding diphtheria toxin A chain operably linked to a osteocalcin promoter. The transgenic mice can be used as a model for metabolic bone diseases since they have decreased bone mass associated with a marked reduction in the number of osteoblasts.

摘要:
Besides fixed display element information for merely displaying a fixed screen, variable display element information for variably displaying a variable display element whose display content changes, input element information representing the relationship of correspondence between the input means and an operation switch contained in a relevant component, and the operation program information for operating the relevant component as required, which are necessary for the relevant component to completely function as a component, are capable of being set and registered with respect to component data. In addition, the set and registered component is allowed to be handled in a component data unit when user screen data is generated. Accordingly, if the components are registered in a library, the possibility of use by a third party can be drastically increased, and the number of work steps during the screen generation by the user can be drastically decreased.
