IPC: A61K35/74
Filed: 1981-07-01
Granted: 1985-02-28
Abstract: A propionibacteria suspension was inoculated into the culture medium, which was treated by gas-pack (BBL method) to give an anaerobic condition. A cultured cell was harvested by centrifugation. The precipitated cell was disrupted by glass beads and a cell disrupter. The suspension-containing cell wall and cytoplasm materials was centrifuged, suspended in a phosphate buffer (pH 7.2). The autolytic entyme was inactivated boiling, and the cell wall was treated with trypsin to remove the remaining protein. Thus, the purified cell wall was lyophilized.

Title: Rotating device control cluster
Inventor: MILLOT JEAN P
IPC: G21C7/18
Filed: 1983-12-07
Granted: 1991-07-23
Abstract: The invention relates to an actuating device for two clusters of control rods movable vertically in one and the same fuel array of the core of a nuclear reactor. The first cluster, used for running the reactor, is connected to a first actuating rod (2), the movements of which are effected by a mechanism (27, 28, 29, 30, 34). This rod (2) carries hooking fingers (41), the operation of which is effected by a device (45) mounted slidingly on the end of the rod (2). The device (45) causes the closing of the fingers by means of a spring (46), or on the contrary their opening by overstroke movement towards the top of the rod (2). The second cluster remaining fully inserted into the assembly during a part of the operating cycle of the reactor is connected to a second actuating rod (3). This second rod (3), fitted coaxially within the rod (2), forms a piston (3b) in this rod (2) driven for its upward movement by the opening of a pressure relief valve (65) of the fluid-tight enclosure (1) in which the actuating rods (2 and 3) move. The rod (3) in the top position can be connected to the rod (2) by the fingers (41) engaging in a groove (53) of the rod (3). The invention is applicable particularly to nuclear reactors with improved efficiency employing neutron spectrum variation clusters.

Abstract: A selection and a setting of the kind of fuel gas and a reference temp. are stored in a CPU. The CPU controls preferentially a set temp. than the reference temp. after a set temp. is inputted and control a hot water feeder. A water rate proportionally regulating valve is set to a desired degree of opening of a set temp. When a previous hit water feeder is used irrespective of ON or OFF of a sub-controller. A geared motor for use in varying a degree of opening of the water rate proportionally regulating valve adjusts a degree of opening after inputting a set temp. resulting in delaying a combustion control. In order to prevent this operation, prior to a starting of combustion, the water rate proportionally regulating valve is moved. So an adjusting time of the water rate proportionally regulating valve from a degree of opening of the initial setting to a degree or opening corresponding to the set temp. is shortened and so the fed-out hot water temp. can be rapidly set to the set temp..

Abstract: The  semiconductor  device  is  manufactured  by  using  the planarization process including the  heat  treatment  of  silicide used as the bit line (6) and reflow of doped glass. The oxinitride (ONO) film (7) is deposited between  the  bit  line  (6)  and  the insulating layer (8) to improve the properties of insulation.  The insulating layer is composed of one of the  BSG,  AsSG,  BPSG  and PSG. Refractory metal silicides  (tungsten  silicide,  molybdenium silicide, titanium silicide) are used as bit line.  The  ONO  film have the same etching rate with the insulating layer.
