Title: Xenon flash lamp
Inventor: MINEKANE TOMIJI
IPC: H01J61/80
Filed: 1983-12-26
Abstract: PURPOSE:To give flash light high brightness and stabilization by supressing a horizontal end-play of flash light basing on the fluctuation in a plasma state. CONSTITUTION:Magnets 5a and 5b are arranged while opposing together negative poles on the perphery of a tube body 1 and along the orbit of a flash light between the anode 2 and the cathode 3. As in this way the magnets 5a and 5b are opposingly arranged along the orbit of the flash light F, the flash light F is also to be sealed in a fixed position all over the orbit and accordingly, a horizontal end-play as in the case of the former xenon flash lamp can be checked thus giving the flash light high brightness and stabilization.

Title: Material to be recorded
Inventor: MORI TAKAHIRO
IPC: B41M5/00
Filed: 1989-09-19
Abstract: PURPOSE:To improve ink absorptivity, blocking resistance property and water resisting property by incorporating polyvinylpyrrolidone copolymer which is bridged with a covalent bond in an ink acceptor layer. CONSTITUTION:An ink acceptor layer is constituted by incorporating polyvinylpyrrolidone copolymer which is bridged with a covelent bond. As a base material, any material can be used when it is a light transmitting base material. For example, polyester based resin and the like can be listed. The molecular weight of the polyvinylpyrrolidone copolymer used in the ink acceptor layer is 10,000 or more, preferably, 30,000 or more. When the molecular weight is less than 10,000, the strength of the copolymer bridged material is decreased even if bridging is performed. Especially, the strength is extremely decreased in a wetting state. Therefore blocking resistance is impaired when a large amount of ink is imparted. As a method for satisfying the blocking resistance property and water resisting property, it is desirable to form copolymer with the vinylpyrrolidone and other monomer. As a preferable copolymer ratio, it is preferable that the polymer ratio of vinylpyrrolidone monomer : other monomer is 60:40-90:1.

Title: Measuring instrument for program executing time
Inventor: SATO HIROAKI
IPC: G06F11/34
Filed: 1987-09-30
Abstract: PURPOSE:To realize the accurate measurement of a program executing time with no limitation given to the measuring conditions by calculating the program executing time based on the executing time of each machine language of an object program. CONSTITUTION:A machine language extracted from an object program memory 11 via a machine language extracting means 12 is sent to a collation means 15. The means 15 obtains the executing time of the corresponding machine language through an all-machine language individual executing time memory 14 and stores the obtained executing time in an executing time memory 13. This procedure is applied successively to the head machine language through the final one of an object program 23. These individual executing times are totalized (added together) by a totalizing means 16 for measurement of the entire executing time of the program 23. Thus it is possible to accurately and easily measure the program executing time without executing the relevant program.

Abstract: PURPOSE:To reduce the uneven distribution of temperature in the inside of an equipment and to prevent the receiving part of a handset from being heated excessively, by covering the surface of the inner side of the equipment of a recessed part where the receiving part of the handset is housed, with a heat insulator from the standpoint of exterior covering. CONSTITUTION:A part 601 of a heat radiating plate is painted with black color, and heat from the heating element of a power unit positioning in the neighborhood of the heat radiating plate is absorbed from the plate. Meanwhile, the neighborhood 602 of the tip part of the heat radiating plate is also painted with the black color, and the radiation of the heat is accelerated. The surfaces of other parts except those two parts are covered with the heat insulator 603. By constituting a device in such way, it is possible to increase heat radiation effect and endothermic effect. As for an exterior cover 1, the inner side of the recessed part 101 where the receiving part of the handset is housed, is covered with the insulator 16. The insulator 16 prevents the exterior cover from being placed in a state where the heat is introduced directly to the exterior cover and the receiving part is heated, and also, forms a heat insulating layer with a heat insulating sheet in which raw material such as glass wool, etc., is used.

Title: X-ray ct apparatus
Inventor: FUJITA HIDEHIRO
IPC: A61B6/03
Filed: 1989-09-22
Abstract: PURPOSE:To reduce a shift quantity of a measured CT value by furnishing an apparatus with a phantom removably, which is photographed together with a top plate which supports a subject or a member analogous to the top plate. CONSTITUTION:When a water phantom is photographed for a calibration, an initialization photographing is carried out under a condition that the water phantom 10 and a top plate-like member 13 are arranged on a slice plane in a photographing zone S. A measured CT value, a reference for the calibration, is not the value for the phantom 10 alone but a value of taking the top plate- like member 13 into account. Therefore, when a real photographing, wherein a subject 3 and a top plate 6 for supporting it are arranged in the photographing zone S, is carried out after finishing the water phantom photographing and removing the water phantom 10 and the top plate-like member 13, there is no influence due to the existence of top plate. A problem that a shift quantity of a measured CT value is larger than that of an actual CT value is improved by the aforementioned method, and the shift quantity of measured CT value is reduced, resulting in an easy preparation of a correct CT image as a diagnostic information.
