摘要:
A compact sensor device having stable sensor characteristics and the production method are provided. The sensor device is formed with a sensor substrate and a pair of package substrates bonded to both surface of the sensor substrate. The sensor substrate has a frame with an opening, a movable portion held in the opening to be movable relative to the frame, and a detecting portion for outputting an electric signal according to a positional displacement of the movable portion. Surface-activated regions are formed on the frame of the sensor substrate and the package substrates by use of an atomic beam, an ion beam or a plasma of an inert gas. By forming a direct bonding between the surface-activated regions of the sensor substrate and each of the package substrates at room temperature, it is possible to avoid inconvenience resulting from residual stress at the bonding portion.

A disk drive apparatus includes: a disk table on which a disk recording medium inserted into a disk insertion port for loading is mounted; an eject lever rotatably supported by a chassis, and having a disk holding part that holds the inserted medium; and a support lever rotatably supported by the chassis and having a disk holding part, wherein these levers are rotated between a waiting position at which the disk holding part waits for the inserted medium and a drawing position at which the medium held by the disk holding part is drawn, wherein when the eject lever and the support lever are at the waiting positions, the disk holding parts are each positioned at a position which is located more on the disk insertion port side than a centering projecting part of the disk table and is not overlapped with the insertion direction of the medium.

A process for fabricating a micro-electro-mechanical system (MEMS) composed of fixed components fixedly supported on a lower substrate and movable components movably supported on the lower substrate. The process utilizes an upper substrate separate from the lower substrate. The upper substrate is selectively etched in its top layer to form therein a plurality of posts which project commonly from a bottom layer of the upper substrate. The posts include the fixed components to be fixed to the lower substrate and the movable components which are resiliently supported only to one or more of the fixed components to be movable relative to the fixed components. The lower substrate is formed in its top surface with at least one recess. The upper substrate is then bonded to the top of the lower substrate upside down in such a manner as to place the fixed components directly on the lower substrate and to place the movable components upwardly of the recess. Finally, the bottom layer of the upper substrate is removed to release the movable components from the bottom layer for floating the movable components above the recess and allowing them to move relative to the lower substrate, while keeping the fixed components fixed to the top of the lower substrate.

A cellulose acetate solution is filtrated with a filter medium formed of cellulose fiber. Hydroxyl groups on the filter medium are substituted to other functional groups. An acidic material is added to the cellulose acetate solution, and the filtration is preformed. In order to estimate the hydrogen ion concentration of the organic solvent, a sample solvent of thereof is mixed with water so as to transport hydrogen ions from the sample solvent to the water of a predetermined volume. Then the water is separated from the sample solvent, and the pH value of the water is measured with a pH meter. The result of the measurement is regarded as the pH value of the organic solvent.

A hybrid electric drive system for a vehicle comprises a combustion engine (1), a transmission (2), a first clutch (3) disposed between the engine (1) and the transmission (2), a rotating electric machine (4) which serves as a motor as well as a generator, a second clutch (30) disposed between the rotating electric machine (4) and the transmission (2), and a storage device (9). When the second clutch (30) is commanded to connect the rotating electric machine (4) to the transmission (2), a control unit (10) controls the rotating electric machine (4) so as to decrease the difference between the rotation speeds of the rotating electric machine (4) and the transmission (2) (S2) and cause the second clutch (30) to connect the rotating electric machine (4) to the transmission (2) only after the difference decreases to a allowable value (S3, S4).

摘要:
Dope containing TAC and a solvent is prepared. The dope is cast so as to form three layers from a casting die. A casting film is formed on a cooling drum. The casting film is peeled as a wet film from a cooling drum by a peel roller. The wet film is transported by a pin tenter and a clip tenter. A tenter draw ratio, which is a ratio between feeding speeds of the pin tenter and the clip tenter and a rotating speed of the cooling drum, is set to not less than 110% and not more than 150%. The wet film is dried in the pin tenter and the clip tenter to obtain a film.
摘要:
An image forming apparatus in which a visible image is transferred to a transfer material includes a pre-transfer exposing unit that makes only a portion of a latent image carrier that corresponds to a leading edge of the transfer material expose, and a transfer-bias applying unit that applies a bias for transferring the visible image. The transfer-bias applying unit starts applying the bias to the transfer material, at least step-by-step, when a predetermined time is passed from a point of time at which the leading edge of the transfer material comes into a contact with the latent image carrier by controlling the pre-transfer exposing unit and a bias applying timing of the transfer-bias applying unit.

A communication terminal capable of preventing a circuit from being released when a hook key is operated in the case the circuit is being closed forcibly. The communication terminal is capable of informing the functions capable of being used in the case the circuit is being closed due to the malfunction of the recording unit. If a recording unit fails to operate and the image memory is exhausted, and when it is set to close the telephone line based on the operation of the circuit closing key, the facsimile receiving is prevented from being carried out by closing the telephone line. The operation of the hook key is invalidated under this condition. Therefore, the telephone line is not released even if the hook key is operated. Thus, when the telephone line is being closed forcibly, the telephone line L is not released even if the hook key is operated.
摘要:
A medical component comprising a human parathyroid hormone peptide or its derivative, and acetic acid contained at a concentration less than its chemical equivalent with respect to the human parathyroid hormone peptide or to its derivative. Since in the medical component acetic acid, which is present as a salt of or attached to the peptide or its derivative, has been reduced to an amount less than chemical equivalent with respect to the human parathyroid hormone peptide or its derivative, a medical component, which is highly stable and will ensure an excellent use feeling when introduced into a pharmaceutical composition, is obtained.
