摘要:
A vehicle obstacle detecting apparatus has an obstacle sensor, an obstacle detecting section, a vehicle response section, a driver operation storing section, a precision determining section and a threshold value updating section. The obstacle detecting section is configured to determine a presence of an obstacle around the vehicle to output a positive obstacle determination based on a similarity value between the detected obstacle information sent from the obstacle sensor and pre-stored obstacle detection reference information with a threshold value. The driver operation storing section is configured to store an average operation characteristic data calculated based on a driver operation. The precision determining section is configured to determine a detection precision of the obstacle by comparing an expected driver operation determined based on the average operation characteristic data with an actual driver operation. The threshold value updating section is configured to adjust the threshold value based on the detection precision.

The reflective liquid crystal display device comprises a polarizing plate disposed forwardly of a liquid crystal cell, a relector which is disposed on backside of the liquid crystal cell and reflects an incident light, and a light-scattering sheet which is disposed forwardly of the reflector and scatters the incident light isotopically. The light-scattering sheet can be prepared with the use of a spinodal decomposition method of coating a mixture liquid containing a plurality of polymers varying in refractive index on a transparent support and evaporating or removing a solvent to form a light-scattering layer having a droplet phase structure. The light-scattering layer includes a light-scattering layer showing a maximum intensity of the scattered-light at scattering angles of 3 to 40°, and a light-scattering layer showing maximums intensity of the scattered-light respectively at smaller angles of 2 to 2° and larger angle &thgr;b.

The invention relates to a continuous liquid infusion device which can be easily prepared for operation with small force, and can infuse liquid at constant infusion rate and amount over a long time. It comprises a liquid syringe section and a driving pump section mounted on the liquid syringe section, wherein sliding the pressing arm of the driving pump section upward leads to axially slides the piston in the negative pressure chamber to produce a negative pressure therein; and using returning force of the piston under the negative pressure, the liquid pushout plunger barrel is biased toward the upper edge of a pressing member through a locking member engaged with the piston so as to push out liquid in the liquid syringe from the liquid infusion port. Further, only the liquid syringe is disposable while the vacuum pump barrel on the driving side is good for repeated use (reusable).

A light-scattering sheet of the present invention can be produced by applying a liquid mixture comprising polymers varying in refractive index (e.g., cellulose acetate), evaporating a solvent, and forming a bicontinuous phase structure due to spinodal decomposition. In the sheet, incident light can be scattered isotropically, and the transmitted and scattered light may have a maximum intensity of a scattered light at a scattering angle of 2 to 40°. Therefore, the transmitted light can be scattered with high directionality. A reflective liquid crystal display unit has a liquid crystal cell with a liquid crystal sealed therein, a reflector for reflecting incident light disposed behind the liquid crystal cell, a light-scattering sheet disposed forwardly of the reflecting means and a polarizing plate disposed forwardly of the liquid crystal cell. The light-scattering sheet realizes a reflective liquid crystal display unit capable of assuring a high quality image.

A photopolymerization initiator comprising an iodonium salt compound; and a photocurable composition containing the compound. The composition is a photocurable cationic composition which cures in a short time upon irradiation with actinic energy rays. They are based on the following findings: (1) a colorless lowly toxic iodonium salt compound can be easily synthesized in high yield when a specific substrate is used as a starting material; (2) a photocurable composition curing in a short time to give a cured article having excellent material properties is obtained by using the iodonium salt compound in combination with a sensitizer; and (3) a highly sensitive photocurable composition which upon irradiation with actinic energy rays cures in a short time to give a cured article having excellent material properties is obtained by using a compound having a group functioning as a cationic photopolymerization initiator, a sensitizing group accelerating the phtoinitiated cationic reaction, and a cationically polymerizable group in the same molecule.

A multiprobe device is provided for a scanning probe instrument and has a plurality of individually-selectable probe members for conducting scanning probe operations. The multiprobe has a plurality of cantilever probes supported by a support member. Each of the cantilevers is individually-selectable for use in conducting scanning probe operations, and each has a different resonance frequency from the others. In a preferred embodiment, portions of the respective cantilevers that are brought into contact with a sample to conduct scanning probe operations are arranged in a substantially linear configuration. A given one of the cantilevers is selected by vibrating the multiprobe at the resonance frequency of the given cantilever.

A scanning probe apparatus and a self-exciting cantilever probe therefor are provided for measuring a characteristic of a sample by scanning a lever of the probe across the sample surface. The probe has a deflectable lever extending from a base and formed integrally therewith, and a resistive body provided on the lever to excite the lever in response to a periodic bias signal applied to the resistive body. In addition, the resistive body has a resistance value that varies in response to deflection of the lever so that the resistance of the resistive body may be monitored to detect deflection of the lever.
摘要:
Processing along one circular path is performed by irradiating a laser beam to a ceramic green sheet attached on an outer peripheral surface of a rotating drum, and the processing path is changed by moving at least one of the rotating drum and a beam irradiated position through a predetermined distance in the direction of drum centerline each time the processing on one circular path is completed. If the laser beam is intermittently irradiated to the ceramic green sheet, a matrix of through holes or concave portions can be easily formed in the ceramic green sheet.
