Abstract: PROBLEM TO BE SOLVED: To obtain a large amount of adventive embryos (torpedo-shaped embryo) of high quality without occurrence of barrier to growth in a shortened time by the high-density culture of a plant cell culture, as the concentration of dissolved oxygen and the pH of the culture medium are controlled. SOLUTION: The high-density plant cell culture (suitably carrot cells) is carried out as the dissolved oxygen concentration is adjusted to at least 15%, and the pH is controlled to a specific value of < 6. In a preferred embodiment, the cultivation is left from the start of the culture until the pH of the culture medium attains 3.8-4.2. Then, the pH is adjusted to 5 at this stage, and the culture is continued further for 20-40 hours, and the pH is adjusted to 5.5. In a preferred embodiment, the culture medium is exchanged. The concentration of the dissolved oxygen is adjusted to a suitable value by feeding oxygen gas into the culture medium. The pH is adjusted by addition of an oxygen gas into the culture medium. The pH is modified by addition of potassium carbonate (0.1 M). The size of cell aggregation used in the cell cultivation is preferably 30-50 μm. This cultivation is preferably carried out by the suspension cell.

As a result, the board 1 is released from a bent state and becomes a horizontal attitude. Then, the other end section of the board 1 is pressed against the first guide section 2 by lowering a second vertically moving clamper 32b.

IPC: G03B42/02
Filed: 1989-05-29
Abstract: PURPOSE:To measure a bone regarding an X-ray photographing film having lightness in a wide range by a method wherein it is decided whether a range of a light transmission amount of a part to be measured is within a range of a light transmission amount of a standard material in a region where a light transmission amount of the standard material satisfies a given resolution condition, and an irradiating light amount is regulated. CONSTITUTION:By means of a quantity of light determined according to a distinction of sex and the age of a person on which bone measurement is effected, a light transmission amount regarding the influence of an aluminum step in an X-ray photograph film run to a given position is determined. In a relation between the determined light transmission amount and the thickness of the aluminum step, the region of the aluminum step in which the thickness difference of one step of the aluminum step is 10 digits or more in a value after A/D conversion is determined, and a light transmission amount of a lower limit aluminum step in the region is L1. Through transfer of the X-ray photograph film, a light transmission amount in a region of only a soft tissue and preferably an average value L2 is determined, L1 is compared with L2. When L1 is higher than L2, comparison is effected in a state in which an irradiation light amount from a light generating means is increased, and an irradiation light amount is increased until L1 is decreased to a value lower than or adjusted to a value equal to L2.

Abstract: PROBLEM TO BE SOLVED: To attain stroboscopic photographing by a portable pixel shift camera by realizing flat stroboscopic light emission at the time of pixel shift photographing. SOLUTION: At the time of pixel shift photographing, flat stroboscopic light emission is realized. At the time of flat light emission control in a stroboscopic circuit, when an Hi light emission control signal Gate is inputted to the base terminal of an IGBT in a state that this is charged by a main capacitor, a trigger circuit is operated, and the light emission of a flash discharge tube Xe is realized. When an Lo light emission control signal Gate is inputted to the base terminal of the IGBT during the light emission, the light emission is interrupted. When the Hi light emission control signal Gate is inputted to the base terminal of the IGBT again, the light emission of the flash discharge tube Xe is realized again. This operation is repeated in higher harmonics.  That is, the Hi and Lo light emission control signals Gate are continuously inputted to the IGBT so that the light emission (flat light emission) with almost constant light intensity can be realized.
