Filed: 1985-03-13
Abstract: PURPOSE:To make a density range of an energy subtraction image maximally suitably visually and to improve the diagnostic function of the subtraction image by setting the density of an optional part of the energy subtraction image at a desired value. CONSTITUTION:An X-ray source 3 emits an X-ray 2 to penetrate an object 1 and irradiate two sheets A and B of accumulating fluorescent body, the energy level being changed between the emissions for A and B, so that a high-voltage image and a low-voltage image are recorded by accumulation respectively in the sheets A and B. A difference signal Ssub is obtained from between a high-voltage image signal SH and a low-voltage image signal SL and the X-ray image is subjected to a processing of energy subtraction. The maximum density and the minimum density desired in the subtraction image are respectively borne by a maximum and minimum density signals Smax and Smin; assuming the maximum and minimum values of the signals SH and SL to be SHmax, SHmin and SLmax, SLmin, a value C is obtained by tan equation I, with which, the density range of the subtraction image is made maximally suitable for human vision.

Title: Pattern forming method
Inventor: FUKUZAWA SHINICHI
IPC: G03F7/38
Filed: 1989-03-03
Abstract: PURPOSE:To improve the reproducibility of stages and the production yield of a semiconductor device by irradiating the surface of a photoresist film after exposing with near IR rays of 750 to 1,000nm wavelength. CONSTITUTION:The photoresist film 32 is formed on an Si substrate 30 which is flat or has steps. The surface of the positive type photoresist film is heat treated for a short period of time from the surface thereof by using IR lamps 42 after exposing. Namely, the near IR rays 44 of 750 to 1,000nm wavelength are transmitted through the ordinary photoresist film 32 and are absorbed in the Si substrate 30 under the film. The heat of absorption is, therefore, generated from the Si substrate side and is transmitted to the photoresist film 32, by which the heat treatment of the film is executed. The nonuniformity of the heat treatment temp. and the unstability of the temp. control are, therefore, eliminated and standing waves 38 are decreased. The good pattern shapes are maintained in this way without damaging the photoresist film 23 and the substrate 30 and the production yield of high-integration LSIs is improved.

Title: Regeneration of moisture adsorbent
Inventor: TANAKA TOSHIO
IPC: B01J20/34
Filed: 1985-03-13
Abstract: PURPOSE:To regenerate a non-conductive moisture adsorbent by a simple method reduced in the loss of regeneration energy, by applying voltage to the non- conductive moisture adsorbent having adsorbed moisture to evaporate adsorbed moisture. CONSTITUTION:Because a non-conductive moisture adsorbent such as a silica gel, activated alumina, a molecular sieve or zeolite slightly takes on conductivity it adsorbs moisture upon the contact with the atmosphere, predetermined voltage is applied to the moisture adsorbent in the regeneration of said adsorbent. Almost no current is flowed to the moisture adsorbent itself and a current is supplied only to adsorbed moisture which is, in turn, evaporated by Joule heat. A current value is lowered with the evaporation of adsorbed moisture and the moisture adsorbent is not almost heated. By this method, the overheating of the moisture adsorbent is prevented and the non-conductive moisture adsorbent can be regenerated by reduced regeneration energy.
