A small-sized electric positioning and clamping apparatus is provided. A panel material is supported on a workpiece supporting face and is positioned by a locating pin being fitted into a positioning hole. A clamp arm is accommodated in a slit formed in the locating pin, and the panel material is clamped by the clamp arm. The clamp arm is coupled to a driven rod, and the driven rod is coupled to a driving rod via a compression coil spring. A cam face is formed in a cam block assembled reciprocably in a gear box, and an engagement cam contacting with the cam face is attached to the driving rod. The cam block is reciprocated by an electric motor via a reduction gear mechanism.

A medical needle device includes a winged shield (4) having a substantially cylindrical shaped shield cylinder (4a) and wings (5, 6) connected to the front end side thereof, a needle base (2) inserted in the shield cylinder (4a), and a needle (1). The wings have wing projections (7, 8) and the shield cylinder has through holes (9, 10) on the wall thereof. By overlaying the wings along the side surface of the shield cylinder, each of the wing projections can be inserted into the inner cavity of the shield cylinder via the through hole. Thereby, without requiring a special operation in the sticking operation, each of the wing projections can prevent the needle base from moving in the axial direction and can hold the needle base in the shield cylinder reliably in a state in which the needle protrudes from the front end of the shield cylinder by a predetermined length.

A solid-state imaging device includes: a semiconductor substrate; and a signal processing section provided on a backside of the semiconductor substrate. The semiconductor substrate has; a first impurity region of a first conductivity type, the first impurity region storing a signal charge produced through photoelectric conversion by a photoelectric conversion section formed in a surface portion of the semiconductor substrate; a second impurity region of the first conductivity type formed below the first impurity region; and a first gate electrode penetrating the semiconductor substrate in a thickness direction of the semiconductor substrate, the first gate electrode transferring the signal charge stored in the first impurity region to the second impurity region. The signal processing section receives the signal charge transferred to the second impurity region.

The opening and closing mechanism is provided at the front grill, and moves the second panel by the driving force of the driving machine to open and close the first intake port.
摘要:
A charged particle beam adjustment apparatus for tilting an electron beam by a tilt deflector is disclosed. The tilt angle adjustment of the electron beam and the distortion adjustment for correcting the image distortion generated when the electron beam is tilted are conducted on a specified sample such as a pyramidal sample. The images before and after the tilting are acquired and processed to determine the tilt angle value and the distortion amount. The tilt angle adjustment and the adjustment for correction of the distortion are automated in accordance with a predetermined processing flow.

In an apparatus for obtaining an image by irradiating a charged particle beam on a specimen, a condition of the beam conditioned differently from vertical incidence as in the case of the beam being tilted is required to be adjusted. To this end, the apparatus has a controller for automatically controlling a stigmator, an objective lens and a deflector such that astigmatism is corrected, focus is adjusted and view filed shift is corrected. The controller has a selector for inhibiting at least one of the astigmatism correction, focus adjustment and FOV shift correction from being executed.

In the process for producing a cyclododecanone by isomerizing an epoxycyclododecane-containing starting material in the presence of an isomerization reaction catalyst containing lithium bromide and/or lithium iodide, in order to perform the reaction with high efficiency (high reaction rate) and high selectivity and stably produce a high-purity cyclododecanone in industry while maintaining a high-level reaction rate, the epoxycyclododecane-containing starting material is produced by contacting an epoxycyclododecadiene with hydrogen in the presence of a hydrogen-reduction catalyst and has a content of the hydroxyl group-containing cyclododecane compounds contained in the epoxycyclododecane-containing starting material controlled to 5 mol % or less.

A refrigerator includes a first compartment, a second compartment, a compressor compressing and discharging refrigerant, a first evaporator connected to the compressor to cool the first compartment, the first evaporator having an outlet, a second evaporator connected to the compressor in parallel with the first evaporator to cool the second compartment, the second evaporator having an outlet, a check valve connected between the outlets of the first and second evaporators to prevent the refrigerant out of the first evaporator from entering the second evaporator, a flow-path switching element for switching a cooling mode between a first cooling mode in which the refrigerant discharged from the compressor is caused to flow through the first evaporator to thereby cool the first compartment and a second cooling mode in which the refrigerant discharged from the compressor is caused to flow through the second evaporator to thereby cool the second compartment, and a control device provided for controlling the compressor and the switching element so that the first and second cooling modes are switched alternately and so that the compressor is stopped under the first cooling mode with drop of the temperature in the either compartment.
摘要:
A process for preparing a diaryl carbonate from a diaryl oxalate in a liquid phase by decarbonylation is conducted by the steps of:1) performing a decarbonylation reaction of a diaryl oxalate in the presence of an organic phosphorus compound catalyst to give a reaction mixture of a diaryl carbonate and the organic phosphorus compound catalyst;2) recovering the diaryl carbonate from the reaction mixture; and3) performing a decarbonylation reaction of a diaryl oxalate in the presence of the reaction mixture from which the diaryl carbonate has been recovered and to which a halogen atom-containing compound is added, to give a reaction mixture of a diaryl carbonate and the organic phosphorus compound catalyst.
