A rotation detecting apparatus for use in producing a photo film cassette has an opaque detecting dog device secured in a manner rotatable together with a rotatable inserter. A light source device applies collimated light flux to the detecting dog device. A detection hole is formed through the detecting dog device, for receiving application of the collimated light flux, and passing light through the detection hole when openings at ends thereof are aligned with one another in a direction of the collimated light flux. A photo receptor receives the passed light passed through the detection hole, and outputs a detection signal according to an amount of the received passed light. In the retention, a trailer of photo film is picked up by the inserter. The inserter is rotationally inserted through a passageway of the photo film cassette. The trailer is fastened on a trailer fastener of a spool.

A liquid jetting pump of the present invention is constructed such that an intra container liquid is sucked into a cylinder 3 through a suction valve 9 by moving a vertically movable member 4 up and down, and the intra cylinder liquid is jetted out of a nozzle 29 through a discharge valve 31 from a stem 28. A plurality of ribs 10 are protruded in a peripheral direction from a lower edge part within the cylinder. Engagement recessed portions 11 are formed in inner parts of the upper surfaces of the ribs. A lower edge of a coil spring 38 for biasing the vertically movable member 4 is secured to each of the engagement recessed portions 11, thereby permitting a flow of liquid on both sides of the lower edge of the spring internally externally.

A thin film producing method in which the wafer film forming processing for a wafer to be a product may be carried out efficiently to shorten the processing time and to raise the operating ratio of the device. In a thin film deposition method using a single wafer processing for forming a thin film by chemical reaction under heat, a pseudo-process is provided which operates to suppress variations in the film thickness caused by the temperature in a reaction chamber 11. This pseudo process is the pre-heating processing of heating the reaction chamber 11 before actually charging the wafer W into the reaction chamber 11.

In a contrast MRA measurement, sampling order of k-space is controlled considering the distance from the origin such that sampling the low-frequency data is performed a time when the contrast concentration reaches it peak. First, the sampling points of k-space are divided into two groups. Then, a measurement of the first group is started a time when the contrast concentration of a blood vessel of interest becomes high and is controlled from the high-frequency component to the low-frequency component such that the distance of a sampling point from the origin progressively decreases. A measurement of the other group, which is performed successively, is controlled from the low-frequency component to the high-frequency component such that the distance of a sampling point from the origin progressively increases. According to this ordering, influence of measurement time error in the contrast MRA measurement can be reduced and the whole blood vessel can be imaged with high contrast. In addition, an artery can be selectively imaged.

A liquid jet pump constructed to suck a liquid within a container on which the pump is mounted and jet the liquid out of a nozzle by pushing down the head of the pump. The nozzle is so formed so as to ascend forward obliquely, and is provided with a discharge valve housing a ball-like valve for closing a valve seat provided at an proximal edge within the nozzle. The valve member is movable both back and forth within the nozzle to keep the liquid from dripping of the nozzle.

A charged beam lithography writes a pattern with charged beams on a sample. The pattern involves various shapes. For every position in the shapes in the pattern, degree of exposure due to a proximity effect caused by backward scattering charged from the shapes surrounding the position is calculated. A charged beam emission quantity corresponding to the calculated degree of exposure is subtracted from a set emission quantity to compensate the proximity effect and obtain an optimum charged beam emission quantity for the position. With charged beams of the optimum emission quantities thus obtained, the pattern is written with high dimensional accuracy.

A double container includes an outer layer body constituting an outer shell; an inner layer body including an upper opening communicating with a containing space, accommodated in the outer layer body, and deformable to undergo volume reduction; an inside plug including a tubular wall extending toward the containing space, a spherical body serving as a valve body being disposed inside the tubular wall; and a dispensing plug fitted to a mouth portion of the outer layer body and including a dispensing tube connected to the tubular wall. The tubular wall includes an inclined wall having a diameter decreasing toward the containing space and configured to abut against the spherical body over an entire circumference and including a protruding wall protruding from the inclined wall to the containing space. The protruding wall includes a liquid holding member holding a pool of liquid medium of the content formed below the spherical body.

A plasma CVD apparatus efficiently coats the surfaces of fine particles with a thin film or super-fine particles by concentrating a plasma near the fine particles. The plasma CVD apparatus includes a chamber, a container disposed in the chamber for housing the fine particles, the container having a polygonal inner shape in a cross section substantially perpendicular to a longitudinal axis of the container, a ground shielding member for shielding a surface of the container other than a housing face, a rotation mechanism for causing the container to rotate or act as a pendulum on an axis of rotation substantially perpendicular to the cross section, an opposed electrode disposed in the container so as to face the housing face, a plasma power source electrically connected to the container, a gas introducing mechanism for introducing a raw gas into the container, and an evacuation mechanism for evacuating the chamber.

A trigger-type liquid sprayer of the present invention is provided with a liquid sprayer body 2 having a nozzle 21 and a trigger lever 22 and a shroud 3 covering the liquid sprayer body 2 and sprays a liquid from a spray hole 211 in the nozzle 21 by a pulling operation of the trigger lever 22. The nozzle 21 is rotatable with respect to the liquid sprayer body 2 and provided so as to open/close a flow passage for the liquid according to a rotational position of the nozzle 21 when an operation lever 24 mounted on the nozzle 21 is rotationally moved, and an abutment portion 31 for positioning the nozzle 21 at a position where the flow passage is opened through abutment of the operation lever 24 is provided at the shroud 3.
