摘要:
The present invention relates to a magnetic shielding case comprising a structure for improving the uniformity in light receiving sensitivity of a phomultiplier while maintaining sufficient magnetic shielding function, and a light detecting apparatus including this magnetic shielding case. This apparatus comprises a photomultiplier and a magnetic shielding case accommodating the photomultiplier. In particular the magnetic shielding case comprises a housing having an opening for transmitting therethrough light to be detected which is directed to the photomultiplier; a lens element for guiding the light to be detected into an effective region on a photocathode; and a positioning structure for placing the photomultiplier at a desired position with respect to the lens element.

An over-loading detection system periodically samples a motor operating parameter, e.g. a revolution speed and an output torque at a predetermined relatively short sampling period. Based on the sampled motor operating parameter, a ratio of the output torque and a predetermined over-load rating torque is derived and stored. Over-load detection is performed with respect to a plurality of sampled ratios of the output torque and the over-load rating torque by deriving a running average and comparing the derived running average value with a predetermined threshold.

A simulation system for an automotive internal combustion engine is suitable for simulating an engine operation for performing a bench test for an engine associated vehicular component, such as an automatic power transmission, an automatic transaxle, a differential gear box, and so forth. The system comprises a power plant which incorporates a relatively high inertia, and means for compensating the high inertia for achieving a low inertia equivalent to the automotive internal combustion engine; an engine characteristics generator receiving predetermined engine operation parameter simulated data for deriving a control signal commanding an output torque of said power plant according to a predetermined engine output torque variation characteristic which is set in terms of said engine operation parameter simulated data, and means, responsive to a simulated engine environmental condition indicative data, for deriving a correction value based on said environmental condition for correcting said control signal.

摘要:
A synthetic multifilament textured yarn provided with randomly formed compact portions and bulky portions formed between two adjacent compact portions. The compact portions are provided with a certain twist and the bulky portions consist of a plurality of individual filaments, each having random crimps. Each of said individual filaments are separated from each other, and the twist direction of each of said bulky portions is opposite from that of two adjacent compact portions. This textured yarn can be produced by a conventional false-twist operation under a processing temperature between a softening point and a melting point of the material yarn.

Provided is a vehicle floor mat reducing a load on a mat main body. The vehicle floor mat includes at least one fastening device for fastening the mat main body to a vehicle. The fastening device includes a first fastening member fixed to the vehicle and a second fastening member fixed to the mat main body. The first fastening member includes a vertical rotating knob, and the second fastening member includes: an insertion receiving section for the rotating knob to be inserted thereinto and engaged therewith; and upper and lower half bodies sandwiching the mat main body and being connected to each other through a half body connecting portion for the rotating knob to be inserted thereinto and at least one outer connecting portion disposed outside the half body connecting portion provided around the insertion receiving section, thus improving a connecting strength between the upper and lower half bodies.

A motor rotor structure for an electric turbo charger is manufactured at low cost with good quality by fixedly fitting, over a shaft, a rotor core having electromagnetic steel sheets pre-formed as an integrated stack. The rotor structure includes a rotor core which is rotated by a magnetic field formed by a stator in a housing; a shaft configured to rotate a compressor impeller and the rotor core together; and a bearing supporting the shaft. The rotor includes the rotor core including the electromagnetic steel sheets; a stopper portion formed at an intermediate portion of the shaft to restrict axial movement of the rotor core; and a pressing unit which presses the rotor core fitted over the shaft against the stopper portion. The pressing unit prevents a circumferential phase shift between the shaft and the rotor core by a pressing force thereof.

A controller of a mobile communication apparatus, such as a cellular phone, that determines whether a received email is urgent by comparing words and phrases contained in the received email with keywords and phrases in a database. The controller generates notice information, such as an icon, when the received email is determined to be urgent, so that a user can recognize that there is an email whose sender wants to contact the user. When the notice information is selected by manipulating a key input device, the controller makes a communication with the sender of the received email.
摘要:
Provided is a vehicle floor mat that can reliably maintain a fixed state and includes a mat main body and at least one fastening device for fastening the mat main body to a vehicle. The fastening device includes a first fastening member fixed to the vehicle and a second fastening member fixed to the mat main body. The first fastening member includes a rotating knob rotating about a vertical axis and a lever pivotally provided on an upper section of the knob. The second fastening member includes an insertion receiving section for the knob to be inserted thereinto, and engaged therewith by rotating the knob inserted into the insertion receiving section. A rotation of the knob in an engaged state is restricted by laying the lever. The knob and lever allow the mat main body to be fixed to the vehicle through a two-step fixation mechanism, thus enabling strong fixation.
