Inventor: KAARU KAMAARANDAA
IPC: H04J3/06
Filed: 1981-03-27
Abstract: 1. A mobile radio network with overall network synchronisation, consisting of a number of radio concentrators (FUKOs) are arranged side by side in the manner of a cellular system with overlapping radio ranges (1, 2, ..., 7), wherein a firmly determined number of radio ranges directly adjacent one another form a radio range group (FGB), all the frequency channels available being repeated in each group, and wherein furthermore the frequency distribution plan for the radio concentrators (FUKOs) is so determined that common channel interference in the particular radio range including an extended edge zone is largely excluded, and wherein at least the signalling is carried out in digital form between the stationary radio concentrators (FUKOs) and the mobile subscriber stations by means of organisation channels (OK) which are designed for duplex operation and have a frame structure, characterised in that overall network synchronisation a radio range (4) spatially in the central zone of the radio network (FN) emits the main reference FUKO by means of its radio concentrator (FUKO), to which main reference FUKO the FUKOs of the radio ranges (1, 2, ..., 7), which surround said main reference FUKO, are synchronised in accordance with a concentric ring structure (O) having a hierarchy which is established from the inside towards the outside, in that in the direction of this ring structure, from the inside towards the outside, each FUKO is assigned at least one of the FUKOs, which are spatially directly pre-arranged relative to the former, as a reference FUKO.

Title: Dust removing method
Inventor: IBATA TOSHIHIRO
IPC: F24F3/16
Filed: 1985-03-06
Abstract: PURPOSE:To prevent dusts and dirts from attaching and accumulating to and on ducts and side walls by introducing into the room, in a case where a material to be dust- removed is not located within the room dust-removed air in an amount smaller than that in a case where a material to be dust-removed is located within the room. CONSTITUTION:A controller 25 switches the output of a drive motor 24 in two stages. In a case where a material to be dust-removed is located within the room, that is, during the dust-removing operation, the flow quantity of air introduced into the room by a sirocco fan is assumed to be Q1, and in a case where a material to be removed is not located within the room, that is, during the non-dust-removing operation, the flow quantity of air introduced into the room is assumed to be Q2. Then, the relation of Q1/5>=Q2>=Q1/50 is established. In this case, Q1 and Q2 are dependent on the room capacity of the ceean room. When the room capacity is represented by Mm3 and the flow quantity of air introduced into the room at the time of the dust-removing operation, is represented by Q1m<3>/hr, Q is set so that the relationship 100M>=Q1>=5M. Even at the time of the non-dust-removing operation, a small flow quantity of clean air is introduced into the room to prevent dusts and dirts from attaching and accumulating to and on the ducts and side wall portions.

A resist pattern is formed to an active element forming prearranged section in the semiconductor substrate 21, and an alumina layer 221 is left through anisotropic etching. The ions of an impurity of the same conduction type as the semiconductor substrate 21 are implanted while using the alumina layer 221 as a mask to shape an ion implantation layer 23. The ion implantation layer 23 is oxidized selectively at a low temperature by using a plasma anodic oxidation method to form an element isolation oxide film 24.

Title: Immunoassay reagent
Inventor: NAKAMURA NANAO
IPC: G01N33/58
Filed: 1990-02-28
Abstract: PURPOSE:To easily obtain the immunoassay reagent which allows an analysis with a high sensitivity and high accuracy by selecting a settling coefft. correlating with liposome in a 0.2X10<6> to 2X10<6> Svedberg range. CONSTITUTION:Phospholipid and glycolipid constituting the liposome are respectively polar materials which respectively have a phosphoric acid group and residual sugar group as hydrophilic groups and both have an acyl group as a hydrophobic group. The hydrophobic groups face an inner side and the hydrophilic groups face an aq. soln. side and the liposome films of multiple layers are formed when the above- mentioned phospholipid and glycolipid are dispersed into the aq. soln. The sensitivity of this reagent correlates with the amplification factor of the internally sealed labeling material which is eluted by the damage of the films. The amplification factor is (1/3)alphar/c when the constant relating to the concn. of the sealed labeling material is (a), the radius of the liposome sphere (r), and the density of the immune complex of the film surface (c). The as prepd. reagent of the (r) from small to large radii hinders the analysis of the high sensitivity and high accuracy and, therefore, the settling coefft. correlating with the grain size of the liposome is regulated and selected to the 0.2X10<-6> to 2X10<-6> S range, by which the analysis reagent of the high sensitivity and high accuracy is obtd.

Title: Side thruster device for ship
Inventor: OOHIRA JIYUNICHI
IPC: B63H25/42
Filed: 1983-03-17
Abstract: PURPOSE:To obtain a side thruster device which requires no complicated control operation with a simple construction, by providing throttle valves between a suction port and each of both left and right discharge ports, respectively. CONSTITUTION:When a control lever 11 is turned to, for example, the left, the opening degree of a left throttle valve 7 is reduced so that a jet directing toward a left discharge port 2 is restricted. The extra part of the jet obtained by this restriction directs toward a right discharge port 3. With this arrangement, there is produced a difference in flow rate between the jets which are jetted from the left and right discharge ports 2, 3, resulting in that thrust force pushing a ship leftward is effected. Then, when the control lever 1 is turned to the position at which the opening degree of the valve 7 becomes zero, the jet flow discharged from a pump 6 is all jetted from the right discharge port 3. On the contrary, in order to produce the leftward thrust force it is sufficient to turn the control lever 11 rightward.
