Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To provide a method of effectively removing the pathogenic factor of transmissible spongy encephalopathy from the solution including physiologically active substances. SOLUTION: A water-soluble organic substance is added to a solution containing physiologically active substance so that the concentration reaches 5-40 wt.% or a salt is added and its concentration is adjusted to 0.3-3.0 M, then the solution is filtered with a membrane filter to remove the pathogenic factor of transmission spongiform encephalopathy. As the physiologically active substances, are cited a solution of blood coagulation factor, human albumen solution or the like. The water-soluble organic substance is, for example, ethanol, polyethylene glycol or the like, while the soluble salt is sodium chloride or the like. According to the present process, the pathogenic factor can be efficiently removed from a solution of physiologically active substance without modification and deactivation of the active substance.

Title: Treatment of waste liquid containing ammonia
Inventor: TANAHASHI MASASHI
IPC: C02F1/58
Filed: 1994-01-19
Abstract: PURPOSE:To provide a treatment method which treats nitrogen originating from ammonia and/or its salts so that the nitrogen content can be reduced to less than 10mg/liter and achieves a continuous treatment in a short time using a compact device. CONSTITUTION:A treatment method for a waste liquid containing ammonia is characterized by decomposing ammonia using activated carbon 3 as a catalyst after adding more than the equivalent of chlorine 2 to an ammonia content to a waste liquid 1 when decomposing and removing the nitrogen content from the waste liquid containing ammonia and/or its salts. If the ammonia content of the waste liquid is highly concentrated, most of the ammonia content is removed from the waste liquid 1 first by a treatment using only chlorine, and then the remaining ammonia content should preferably be decomposed using the activated carbon 3 as a catalyst. In addition, the pH value after decomposition and removal of the ammonia content should preferably be adjusted to at least 9.0.

Filed: 1990-01-31
Abstract: PURPOSE:To give not uncomfortableness to a driver when the acceleration operation is changed to the normal operation by making the air fuel mixture lean when the smoothed value of the pressure in an intake passage is stored in a memory means and becomes higher than the pressure in response to the throttle opening by a fixed value or above. CONSTITUTION:The smoothed value of the absolute pressure in a surge tank 10 is calculated, and the absolute pressure in the surge tank 10 during the normal operation is calculated based on the throttle valve opening detected by a throttle sensor 17 and the engine rotating speed detected by a rotating speed sensor 30. When the absolute pressure during the normal operation stored in a ROM 22 is subtracted from the smoothed value, a deviation D is calculated, the deviation D until the negative acceleration G becomes the maximum after the intake air quantity starts to be decreased is determined as a fixed value Do in advance, when the deviation D exceeds Do, the theoretical air-fuel ratio is switched to the lean air-fuel ratio. The acceleration operation can be surely changed to the normal operation, and the air fuel mixture can be made lean when the intake air quantity starts to be decreased.

Title: Simple film loading device of camera
Inventor: TOYODA KENJI
IPC: G03B17/26
Filed: 1979-02-22
Abstract: PURPOSE: To make film loading easy and make the film after loading difficult to remove by providing a slit to an elastic body constituting part of a spool and widening the slit at the film loading.  
     CONSTITUTION: When a back cover 9 is held closed, a detention lever 6 engages with the outside circumference 3a of a receiving part and an elastic body 2 is not deforming. When a film-loading operation member is lifted, a lever 5 is pulled up and a receiving shaft 3 is forced up by a flexed part 5a, by which the spacing between the step part 1a of a spool center shaft 1 and shaft 3 is narrowed to buckle and deform the elastic body 2 axially, resulting in the widened spacing with the shaft 1. Hence, the slit 2a opens in arc form and the lever 6 falls down to the small- diameter circumferential surface 3b of the shaft 3, causing the resetting of the shaft 3 to be detained. A film is then sandwiched between the shaft 3 and the slit 2a.
