An optical information reading apparatus is provided which is made of an assembly of a barcode reader and a personal digital assistant (PDA). The barcode reader and the PDA are joined through an attachment. The barcode reader includes a joint detector working to detect the joint to the PDA and a communication system establishing communication with the PDA. The barcode reader works to transmit barcode data to the PDA through the communication system only when the joint detector has detected the joint to the PDA, thereby providing ease of operability, useability, etc.

Provided is a liquid heating apparatus capable of heating fluid such as peroxosulfuric acid solution to high temperature in a short time. The heating apparatus includes: a flow channel member forming a flow channel 4 allowing liquid to flow and having flow channel thickness of 10 mm or smaller, the flow channel member composed of material transmitting near-infrared rays; and a near-infrared heaters 7, 8 placed over the outside of at least one of opposite flow channel surfaces of the flow channel and heating the liquid in the flow channel. The liquid flowing through the flow channel is instantaneously and evenly heated using near-infrared rays. It is preferable that spacers 6 be further provided within the flow channel 4 in order to limit the volume of the flow channel. Since not only the residence time in the heating apparatus can be shortened but the possible largest heat transfer area can be also maintained by decreasing the volume of the flow channel of the heating apparatus and by increasing the flow velocity in the heating apparatus, it is possible to increase the temperature of liquid to be heated to high temperature in a very short time even if the preset temperature of heat transfer surfaces is low.

摘要:
A seat apparatus used by a worker when effecting a job on an automobile is disclosed. The seat apparatus includes: a two-axis support device located above a horizontal feed path of an automobile body, for supporting a suspension carriage such that the carriage is movable in a substantially horizontal plane; a hanger arm attached to the suspension carriage; and a seat member provided on a lower end portion of the hanger arm which can enter the automobile body through its side opening, in a direction perpendicular to the feed path of the body. The seat member on which the worker sits is movable with the suspension carriage in the direction perpendicular to the feed path, and is thus selectively located in a retracted position outside the automobile body, or a working position inside the automobile body, at which the worker is able to effect the job.
摘要:
A process is disclosed which prepares a low pressure mercury vapor discharge lamp having a bulb and an end plate connected to the bottom of the bulb. The steps involve the application of an adhesive on one surface of the end plate, and the subsequent insertion of an exhaust tube into the end plate in such a way that an enlarged diameter portion of the exhust tube has an adhesive formed on this portion. As a result of the location and the structure of the steps, it is possible to provide a single step method of heating which functions to perform the essential bonding of all parts.
摘要:
Both legs (1a, 1b) of a U-shaped bulb are brought into a mutually contacting state or are opposed to each other with a space of gap (31) and end parts (1a', 1b') of the legs are directly put on an end plate (10) so as to form an electric discharge path in the U-shaped bulb. Since the legs (1a, 1b) are in contact with each other within limit of elastic deformation of a connecting part (2a) of the bulb (1), breakage of the bulb is avoidable even when an external force is applied to the bulb so as to bring the legs (1a, 1b) closer.
