摘要:
An engine valve feed apparatus which feeds engine valves to a valve handling apparatus at a valve pick-up station where the valve handling apparatus picks up and fits the engine valves to an engine cylinder head one after another. The apparatus comprises a valve hanger plate formed with a number of valve holes for tightly receiving a number of engine valves to hang the engine valves upside down. A hanger plate transfer unit transfers a number of the valve hanger plates to the valve pick-up station cone after another. An engine valve thrust-up unit is disposed at the valve pick-up station for thrusting up the valves from the valve hanger plate at the valve pick-up station so as to allow the valve handling apparatus to hold a stem of each of the engine valves. The engine valve thrust-up unit has a holding member movable up and down and formed with a number of positioning holes for receiving the stem ends of the engine valves hung from the valve hanger plate to thereby hold the valves upright when moved up. A stopper prevents the valve hanger plate from being forced up when the stem ends of the engine valves are pushed up from the valve hanger plate.

An article picking up mechanism for picking up articles placed in a container one by one for assembling the articles on works. The mechanism includes a tiltable table for receiving the container and tilting it to thereby shift the articles to one side of the container leaving a space in the other side. A manipulator robot is provided to shift one of the articles toward the space and grip the article to take out of the container.

A printing apparatus which communicates with a data providing apparatus includes a printing mechanism which executes a printing operation. The printing apparatus receives a number of print copies, and acquires print data from the data providing apparatus by executing a request processing of transmitting to the data providing apparatus a data request of the print data, and a reception processing of receiving the print data from the data providing apparatus. When executing a printing operation of N copies (N is an integer of 2 or larger), the acquiring executes, for each copy, the request processing and the reception processing to acquire the print data from the data providing apparatus while executing the request processing of the print data of M-th copy (M is an integer of 2 or larger and N or smaller) after the reception processing of the print data of (M−1)-th copy is completed.

In accordance with an embodiment, a defect inspection apparatus includes a charged beam irradiation unit, a detection unit, an energy filter, and an inspection unit. The charged beam irradiation unit generates a charged beam and irradiates a sample including a pattern as an inspection target thereon with the generated charged beam. The detection unit detects secondary charged particles or reflected charged particles generated from the sample by irradiation of the charged beam and outputs a signal. The energy filter is arranged between the detection unit and the sample to selectively allow the secondary charged particles or the reflected charged particles with energy associated with an applied voltage to pass therethrough. The inspection unit applies voltages different from each other to the energy filter and outputs information concerning a defect of the pattern from an intensity difference between signals obtained under application voltage different from each other.

An ink ribbon cassette includes first and second rotatable bodies that rotate with an ink ribbon held between the rotatable bodies in sandwiched relation. The second rotatable body includes a hole through which a shaft extends such that the second rotatable body is rotatably supported on the shaft. The shaft may have a circumferential surface conical toward the free end, and the hole may be a conical hole into which the conical shaft extends. The shaft may include a plurality of cylindrical shaft portions that are in line with one another and that have different diameters. The second rotatable body is formed with a plurality of cylindrical hole portions having different diameters corresponding to the cylindrical shaft portions such that the second rotatable body is rotatably supported on the shaft.

The present invention relates to an apparatus and method of frame synchronization in broad band wireless communication systems. In an apparatus of frame synchronization in a mobile station, a time variant phase rotation compensator eliminates time variant phase rotation carried in received signals by conjugated multiplication between adjacent signal samples. Then, the processed signal is fed into a delay correlator to calculate a plurality of correlations between two successive frames. A local power calculator acquires an average power of several symbols centered on delayed correlation values. A normalizer normalizes the delayed correlation values with a local average power corresponding to the delayed correlation values. A maximum value detector selects the maximum value from normalized correlation values to trigger frame synchronizing and timing signals.

A semiconductor substrate inspection method includes: generating a charged particle beam, and irradiating the charged particle beam to a semiconductor substrate in which contact wiring lines are formed on a surface thereof, the contact wiring lines of the semiconductor substrate being designed to alternately repeat in a plane view so that one of the adjacent contact wiring lines is grounded to the semiconductor substrate and the other of the adjacent contact wiring lines is insulated from the semiconductor substrate; detecting at least one of a secondary charged particle, a reflected charged particle and a back scattering charged particle generated from the surface of the semiconductor substrate to acquire a signal; generating an inspection image with the signal, the inspection image showing a state of the surface of the semiconductor substrate; and judging whether the semiconductor substrate is good or bad from a difference of brightness in the inspection image obtained from the surfaces of the adjacent contact wiring lines.

An air conditioner for a vehicle includes a vapor compression refrigeration cycle switchable between a heat pump cycle and a cooler cycle, a heat core configured to heat air to be blown into a vehicle compartment by using coolant of an engine of the vehicle as a heat source, and a controller configured to control operation of the vapor compression refrigeration cycle. The controller controls the vapor compression refrigeration cycle to be operated as the cooler cycle so as to perform a defrosting control of the outdoor heat exchanger, and outputs an operation request signal to the engine, when the controller determines that the outdoor heat exchanger is frosted.
