摘要:
The invention provides a hologram-recording subject plate comprising a block and a variety of subjects fixedly contained therein, which ensures easy, stable yet continuous recording of a multiplicity of identical holograms or different holograms reconstructible by illuminating light, , a hologram-making method using the same, and a hologram-recorded article. The subject plate comprises a transparent solid block and a hologram-recording subject contained therein. A photosensitive material film is applied directly onto one surface of the subject plate, and the subject plate is then irradiated with laser light through the photosensitive material film. Such simple operation enables a multiplicity of identical holograms to be recorded in an easy, stable yet continuous manner.

A system which enables a film, e.g. a photosensitive material film, to be continuously laminated on and delaminated from a surface of a substrate, e.g. a hologram original plate, and allows duplication to be continuously effected. The system includes a film supply part (32) for supplying a film (1), a film laminating part (37) for continuously laminating the supplied film (1) on a film laminating substrate (35), a film delaminating part (37') for continuously delaminating the film from the substrate (35), and a film take-up part (43) for taking up the delaminated film. In the system, no air bubbles are trapped when the film (1) is laminated on the substrate (35), and no peel unevenness, e.g. undesired line, occurs when the film (1) is delaminated from the substrate (35). The system is suitable for use in a hologram duplicating apparatus, a dimple relief pattern duplicating apparatus, a microscopic test sample preparing apparatus, etc.

A catalyst for obtaining pyromellitic anhydride at a high raw material gas concentration with high yield and a method for the production of pyromellitic anhydride are provided. The catalyst containing vanadium and silver as essential component elements for catalyst and having an atomic ratio of silver to vanadium in the range of from 0.001 to 0.2 allows efficient production of pyromellitic anhydride by the vapor-phase oxidation of a tetraalkylbenzene with a molecular oxygen-containing gas. The method of this invention accomplishes the production of pyromellitic anhydride by the use of the catalyst.

An attachment for an electronic switch having an outlet tube in one embodiment includes a first clamp member including a pair of legs having respective hooks on ends thereof, and a second clamp member having a pair of locking pawls for locking engagement with the hooks, respectively. In a second embodiment the clamp members are identical with a leg and hook and a pawl on each member. The second clamp member having a pair of cavities in which the legs can be fitted, respectively, the first and second clamp members being connectable together to hold the outlet tube of the electronic switch therebetween. The first and second clamp members as connected together are slidable between a first position in which one of the first and second clamp members is displaced away from the other while being retained together by the hooks and the locking pawls and the outlet tube is rotatable between the first and second clamp members, and a second position in which the one of the first and second clamp members is pushed against the other and the outlet tube is fixed in position between the first and second clamp members.

A collecting chute for collecting weighed articles discharged from an automatic weighing system divided into left and right sections. Each section has an inner article receiving portion and an outer article receiving portion. Two article discharge portions are provided side-by-side at the bottom end of each section. The left and right sections each include an upper, outer chute and a contiguous lower, outer chute, an upper, inner chute and a contiguous lower, inner chute, and a discharge chute contiguous to the lower, outer chute. The left lower, inner chute has an outlet which extends solely into the right lower, outer chute, and the right lower, inner chute has an outlet which extends solely into the left, lower outer chute, thereby communicating the left and right lower, inner chutes with the right and left discharge chutes, respectively. The upper, outer chutes and the upper, inner chutes are capable of being disassembled into plural component parts.

A hopper for an automatic weighing apparatus has a link mechanism for opening and closing a hopper gate and an attachment mechanism for attaching a hopper body to the automatic weighing apparatus. The link mechanism includes a drive link pivotably mounted on a bracket, a follower link angularly movable in unison with the gate, and an intermediate link interconnected between the movable ends of the drive and follower links. When the gate is closed, the drive and intermediate links are aligned along a substantially straight line to prevent the weight of articles in the hopper from opening the gate. The attachment mechanism includes a pair of brackets attached to and projecting from the hopper, two parallel shafts mounted on and between the brackets, at different distances from the hopper body, and an attachment member mounted on the automatic weighing apparatus and having upwardly opening recesses for receiving the shaft closest to the hopper body and downwardly opening recesses for receiving the shaft farthest from the hopper body.

A heat source device is provided with a differential pressure sensor that measures the differential pressure between an inlet pressure and an outlet pressure for the chilled water in an evaporator and with a control device. The control device possesses the coefficient of loss for the evaporator and is provided with a chilled-water flow-rate computing portion that calculates a chilled-water flow rate at the evaporator on the basis of the coefficient of loss and the differential pressure output from the differential pressure sensor; a control-command computing portion that generates a control command by using a specification heating-medium flow rate that is set in advance; and a control-command correcting portion that corrects the control command generated by the control-command computing portion.
