Abstract: Provided is a technology for minimizing drop in measurement accuracy due to variation in detection sensitivity of an MEMS by minimizing variation in eigen frequency of the MEMS caused by stress.  Fixed portions (3a-3d) are displaced outward in the y-direction of a semiconductor substrate (2) by deformation of the semiconductor substrate (2).  A movable body (5) is insusceptible to deformation of the semiconductor substrate (2) because being arranged in the state floating from the semiconductor substrate (2), and thereby the movable body (5) is not displaced.  Consequently, tensile stress (+σ 1 ) is generated in a beam (4a) and compressive stress (-σ 2 ) is generated in a beam (4b).  Considering a spring system combining the beam (4a) and beam (4b), increase in spring constant caused by tensile stress acting on the beam (4a) and decrease in spring constant caused by compressive stress acting on the beam (4b) are offset.

Filed: 2009-08-07
Abstract: Disclosed is an electric tool equipped with a speed-changing device that automatically changes speeds in response to an increase in external torque added to a spindle, wherein the screw-tightening operation can be performed faster than with the prior art. In the high-speed, low-torque mode prior to an automatic speed change, an extremely high output rotational frequency is set to a degree such that an output torque is insufficient to perform screw tightening to the end. The output rotational frequency prior to the speed change is set in a range of approximately 4.5‑6.0 times that of the output rotational frequency after the speed change. Thus, with the initial screw tightening the work can be performed quickly with a higher rotational speed than with the prior art, and after the automatic speed change the screw tightening can be completed with a large output torque.

Abstract: The disclosed acoustic-feel adjustment device can appropriately adjust how sound reflects above a sound source, providing an acoustic feel close to that of a high-ceilinged space without large-scale engineering work such as the provision of sound-absorbing materials on the ceiling. A sound-absorbing body (10) supported by a mount (20) is provided above musicians (80) or other subjects, in the middle of a propagation path by which sound from a sound source such as instruments (70) reflects off the ceiling (50) of the room and returns to the aforementioned subjects. Said sound-absorbing body helps prevent a state in which sound emitted from the sound source reflects off the ceiling (50) and then returns as is to the subjects. The manner in which and degree to which sound reaches the subjects from above is thus made similar to that in a space with a ceiling significantly higher than that of the aforementioned room. Even in an ordinary indoor space, the subjects can thus be provided with an acoustic feel that is extremely close to that of an actual performance space with a high ceiling, such as a hall. Consequently, even in a room with an ordinary structure, subjects practicing for an instrumental, vocal, or other performance can be provided with a practice environment that differs little from the actual performance space, making the actual performance feel more comfortable.

Title: Internal combustion engine controller
Inventor: NISHIJIMA HIROKI
IPC: F01N3/00
Filed: 2010-08-17
Abstract: The present invention provides an internal combustion engine controller which includes: a particulate matter sensor (2) for measuring the amount of particulate matter in a gas, the sensor (2) being equipped with a pair of electrodes (8, 10) disposed with a space therebetween; and a removing means (16) for burning and thereby removing particulate matter which has been adhered to the particulate matter sensor. The controller is adapted such that in the step of removing particulate matter, it is determined whether the amount of particulate matter adhered to the particulate matter sensor is less than the reference amount of particulate matter which is set as the minimum amount of residual particulate matter at which the pair of electrodes conduct at least at one point or more. If the amount of particulate matter is determined to be less than the reference amount of particulate matter, then the step of removing the particulate matter (PM) by the removing means is ended. It is thus possible to sense the amount of PM according to a sensor output even immediately after the removing step, while saving power in the step of removing the PM that has been accumulated on the device portion of the sensor.
