Title: Agent for preventing adhesion of thallium 201 to container
Inventor: FUKUSHIMA MAKOTO
IPC: C07D307/62
Filed: 1993-03-05
Abstract: PURPOSE:To remarkably suppress the adhesion of thallium 201 to a container while keeping the nuclear medical properties of the element absolutely without influencing its chemical and biological properties. CONSTITUTION:A solution containing thallium 201 and useful as a radioactive diagnostic to be used in myocardial or neoplasm scintigraphy or local brain perfusion scintigraphy is incorporated with a reducing substance commonly known as a reducing agent or an antioxidant, e.g. L-ascorbic acid, sodium sulfite or hydroquinone to suppress the adhesion of thallium 201 to the container. The adhesion of the element is essentially completely inhibited by the treatment to enable the administration of accurate dose of the radioactive substance. Furthermore, the disposal of the container and the exposure management of workers can be carried out without taking particular care.

Abstract: PURPOSE:To reduce the number of component parts by digitally processing a brightness signal and color signal of VTR outputs and causing the delay by a memory. CONSTITUTION:The reproduced signal of the VTR from a terminal 1 is passed through a brightness signal processing part 15 where the brightness signal is demodulated. The demodulated signals are A/D converted at 16, and 0.5H skew is detected at 24 from the horizontal synchronization signals separated at the synchronization circuit 23. Burst gate pulses are generated at 25 and are both inputted into a control signal generator 26 from which control signals (c), (d) are produced, The brightness signals digitized at 16 are processed at 17 as prescribed and are delayed by 1H at a memory 13. The color signals passed through the LPF 2 are A/D converted and separated at 4 into color difference signals B-Y, R-Y and delayed by 0.5H at memories 7, 8. The signal delayed by 1H of the brightness signal and the signal not delayed are alternately switched by the signal (c) with the signal delayed 1H of the color difference signal and the signal not delayed, while the signal R-Y code inverted at 11 and the signal not inverted are switched at the burst period signal (d) to make D/A conversion.

A side plate 4 is arranged on one side of the first blade 5, and a second blade 6 is arranged on the sucking side. The first blade 5 has the same effect as that of a conventional centrifugal fan, while the second blade 6 has, in its sucking side, a passage formed between a pressure bulkhead 9 for separating a sucking passage 7 from a blowing passage 8 and the side plate 4 to suck and blow the air in the part larger than the sucking side bore of the first blade 5 to the blowing passage when the motor is rotated. Therefore, the air quantity is increased by the addition of the area of the blowing passage, and a high head can be provided. When the rotating speed is lowered by the increase amount of air quantity, thus, noise can be reduced.

Title: Mounting structure of neg strip in vacuum vessel
Inventor: TSUCHIYA MASAO
IPC: H05H7/14
Filed: 1989-02-27
Abstract: PURPOSE:To absorb the thermal expansion of NEG strips so as to simplify the mounting structure thereof by fixing and supporting the NEG strips respectively with holding them in bending at suitable intervals within a vacuum vessel. CONSTITUTION:NEG strips 41, 42 are fixed to a ceramic stationary supporting stands 34 mounted onto a base plate 32 with holding the strips in bending 45 by the use of screws 46, and then interconnected by the use of connecting plates 48, 50 or the like. When voltage is impressed on an electrode 58 or the like, Joule heat is generated in the NEG strips for heating them to an extent of 450 degrees centigrade. Although at this moment, the NEG strips are thermally expanded, the bending 45 grows larger to absorb the thermal expansion since the bending 45 is made in a direction becoming more distant from the inside wall of a chamber in each of their initial conditions. This makes it unnecessary to support the NEG strips with springs or the like, thereby simplifying the mounting structure of the strips.

Abstract: PURPOSE:To prevent a head from being skipped by wiping off a head landing area on a magnetic drum after a cleaning blade is separated from the magnetic drum and landing a recording head. CONSTITUTION:A toner which is not transferred and left on the magnetic drum is scraped off by the cleaning blade 14 of a first cleaning device, it is absorbed in vacuum at a suction part 15 and recovered into the filter bag.
