Title: Radio communication system
Inventor: SEKI YOSHINORI
IPC: H04B7/005
Filed: 1989-03-29
Abstract: PURPOSE:To save the power consumption by deciding a level of a connection request signal, returning the result and allowing plural mobile stations to control transmission power in response to a level data when a base station receives a connection request signal from one of the plural stations. CONSTITUTION:A mobile station 20 sends a connection request signal S1 at a minimum transmission level from a transmission section 23 and increases sequentially the transmission level up to a maximum level till a reply comes from a base station 10. When the base station 10 detects a connection request signal S1 addressed to its own station at its reception section, the reception section decides (15) a reception level at that point of time by a level deciding control section 15, and returns a connection reply signal S2 from a transmission section 13 via a control section 14 corresponding to the reception level. The mobile station 20 controls the power to a transmission power corresponding to the reception level included in the connection reply signal S2 by a control section 24 and the communication is started via the transmission section 23 and a power control circuit 25. When the transmission power of the mobile station 20 is a maximum, an annunciator 26 displays the power. Thus, the mobile station 20 is prevented from being stepped out of the service area of the base station and the transmission power consumption is saved.

IPC: H01L21/52
Filed: 1981-05-20
Abstract: PURPOSE:To enable to perform the evaporation treatment of In to a laser mount material and the surface treatment by etching with plural number of pieces at the same time when formation of metal film is to be performed by a method wherein platinum is provided on the surface of an evaporation pedestal. CONSTITUTION:Cu blocks 19 of plural number of pieces being the laser mount material are put at the same time as the material to be evaporated on a flat glass plate 15 to be used as the evaporation pedestal. A Pt layer 17 is formed on the glass plate 15 interposing a Ti layer 16 between them to form the evaporation pedestal. The Ti layer 16 is provided for intensification of adhesion between the glass plate 15 and the Pt layer 17. In of the solder material is evaporated on the Cu blocks 19 put on the evaporation pedestal by this way, and the In solder film 18 is formed on the evaporation pedestral consisting of the Cu blocks  19, the glass plate 15, the Ti layer 16, and the Pt layer 17. The Pt layer 17 is made to be exposed on the surface of the evaporation pedestral like this. Because mutually adhering intensity of the Pt layer 17 and the In solder film 18 is sufficiently large, even when etching of the film 18 is performed in the condition that the blocks 19 are put thereon, the situation that the film 18 is peeled off from the evaporation pedestal is not generated.

IPC: G03B21/11
Filed: 1988-04-01
Abstract: PURPOSE:To perform subsequent retrieval operation efficiently by feeding an information storage medium automatically, reading its marks, and storing all pieces of mark information when the information recording medium is set on a device main body. CONSTITUTION:When a microswitch 2 detects a microfilm where images are recorded being inserted (set) into the device main body at a specific position, a motor is driven through a motor driving control circuit 36 and the film begins to be fed automatically. When a mark detector 22 sends out a mark detection signal to a microprocessor 30 as the film is fed, information on the mark is stored in a memory. Further, when the film is fed to its rear end, the feeding of the film is stopped. Thus, pieces of information on marks on the film are all stored in the memory. Consequently, the retrieval time is shortened greatly.

Abstract: PURPOSE:To make a stop setting mechanism movable up to the stop position assigned by the signal from an exposure control circuit by driving each mechanism to the maximum stop position by the revolution in the 1st direction of a motor in a single-lens relfex camera. CONSTITUTION:A film winding mechanism 208 winds a film by one frame and a shutter 209 is set by a shutter charging mechanism 203. The revolution in the 1st direction of a motor 200 is transmitted to a stop setting mechanism 204, and the mechanism 204 is driven up to the maximum stop position and is held. As the motor 200 revolves in the 2nd direction, a mirror set mechanism 205 moves a mirror 207 upward, and before the mirror arrives at the top, the mechanism 204 is fed up to a specified value by an electromagnetic ratchet 210 so that a stop 206 attains the specified value. When a shutter 209 is released, a CPU 102 emits the rotation command to the 1st direction of the motor 200 to a driving circuit 106, thereby winding up the film and setting the shutter charging and stop mechanisms in the maximum open positions.

CONSTITUTION:A sample liquid flows through a valve V1 into a boric acid concentration measuring device 1 and is returned to a system from a valve V3. When the valves V1, V3 are full opened and the other valves V4, V6 are opened, the sample liquid of the outlet side of a resin tower 6 flows through the valve V4 and the vessel 1 and is returned to a system from the valve V6. <24>Na and <56>Mn which are a neutron radiation source are removed in the resin tower 6. When a counting rate is made I at the time of normal measurement, the difference Ip with a counting rate Ic at the time of correction can be removed in the resin tower 6. As the result, in the case where rate change of the neutron radiation source and a photoneutron source is small, the influence of photoneutrons can be corrected without a counter tube with a Cd filter.

Abstract: PROBLEM TO BE SOLVED: To obtain the amount of wear accurately by calculating the rotation angular velocity of the cutter head of a tunnel boring machine and the rotation angular velocity of a disk cutter, and the mounting diameter and the depth of cut in the natural ground. SOLUTION: The hub 1a of multiple disk cutters 1 mounted on the front face of a cutter head is borne on a fixed shaft 2 through bearings 4 in a rotatable manner. A rotation detector 7 for the disk cutters 1 is provided on the circumference of the fixed shaft 2 between the bearings 4, the rotation angular velocity is conveyed to a computer 9 through a cable 8 and displayed on a display 10. When the main body of a shield is advanced into the ground while rotating the cutter head, the edges of the disk cutters 1 cut into a cutting face and excavate it. A difference in rotation angular velocity occurs between the contact section of the sides of the edges and the surface of the natural ground and the edge section and produces slipping.  The diameter of the disk cutters 1 is obtained from excavation distance, cutter head revolution speed, rotation angular velocity and the mounting diameter of the disk cutters 1 of the cutter head.

Inventor: WADA TOMOHISA
IPC: H01S3/036
Filed: 1994-04-18
Abstract: PURPOSE:To make it possible to automatically discharge residual fuel when a fuel bleed apparatus for carbonic acid gas dynamic lasers is stopped. CONSTITUTION:Liquid fuel 7 flows, through a fuel feed valve 1 and a pipe 16, into the manifold 11a of an injector 11, and then enters a combustion chamber 12. An oxidizing agent flows through an oxidizing agent feed valve 10 and a pipe 17, and also enters the manifold 11a. Another pipe 18 branches from the pipe 16, and is connected to a catch tank 6 through a bleed valve 2. Purge gas 9 is connected, through a purge valve 3a, a check valve 5 and an orifice 4b, to the port 11b in the manifold 11a, and it is also connected, through a valve 3b and an orifice 4b, to the pipe 17. When the valve 1 is closed and the valves 2, 3 are open, therefore, the purge gas 9 flows through the orifice 4 and the manifold 11a and discharges fuel remaining in the pipe 16, through the bleed valve 2, into the catch tank 6. This prevents soot from being produced after the start of operation.
