Title: Measuring method of azimuth if separation of interference of two signals
Inventor: YASUJIMA AKIHIRO
IPC: G01S3/48
Filed: 1990-02-28
Abstract: PURPOSE:To measure the azimuth of two interfering waves as to a group of antennas disposed in the shape of an equilateral triangle which is advantageous for an antenna construction, by utilizing a periodical change in a phase difference between adjacent antennas due to a minute frequency difference between the frequencies of the two waves. CONSTITUTION:It is utilized for determination of an azimuth that there is a difference between the frequencies of two waves, through every small, and that parameters to be measured change periodically due to this frequency differ ence. Concretely, all phase difference between adjacent antennas in a group 1 of antennas disposed in the shape of an equilateral triangle are determined respectively, first, and the maximum phase difference is determined from the periodical change in each phase difference. Then, prescribed simultaneous equations wherein azimuth angles phi1 and phi2 to be measured of the two waves and the ratio relationship (E1-E2)/(E1+E2) between amplitudes E1 and E2 thereof are unknown variables are solved with respect to three maximum phase differences determined by this method, and thereby the azimuth angles phi1 and phi2 are determined.

Title: Powder medicine take-out device and powder medicine container carrying device
Inventor: ISHII YASUHIRO
IPC: A61J3/00
Filed: 1998-02-12
Abstract: PROBLEM TO BE SOLVED: To automatically and efficiently take out various kinds of power medicines though human intervention is interposed. SOLUTION: This powder medicine take-out device is provided with many powder medicine cassettes 30, a cassette moving mechanism 20 moving these cassettes 30 and carrying mechanisms 10 and 110 carrying powder medicine containers 1 receiving powder medicine taken out from the cassettes 30, and all or a part of the carrying routes of the mechanisms 10 and 110 are folded. As many containers 1 can be stored on the carrying routes, taking out from the power medicine cassettes to the containers 1 is not stopped easily though the supplying timing of the containers 1 to a following device is delayed. Thus, the degree of freedom concerning direct or indirect cooperation with the following device is increased while keeping throughput, therefore the availability of a device is improved.  In addition, 'be folded' means a state where the carrying routes are bent to a degree capable of temporarily keeping some degree of powder medicine containers on the carrying routes beyond a state where the carrying routes are bent merely in order to change a carrying direction.

IPC: F04D29/08
Filed: 1994-03-17
Abstract: PURPOSE:To shorten an overhang, to reduce a bearing load, to suppress bending of a main shaft to a low value, and to reduce size and weight by a method wherein a bearing on the side in the vicinity of an impeller is disposed integrally with a shaft sealing device. CONSTITUTION:In a centrifugal pump being of structure wherein a main shaft 2 is in a cantilever, a bearing 5 on the impeller side near an impeller 1 to support the main shaft 2 is disposed integrally with a shaft sealing device 10. Further, a self-lubrication type bearing or a pumped-up liquid type lubrication type bearing is used as a bearing 5 on the impeller side. Thereby, since an overhang is sharply shortened, the bearing load of the bearing 5 on the impeller side is reduced and bending of the main shaft 2 is suppressed to a low value. As a result, the diameter of the main shaft 2 is reduced to a value lower than that of a conventional type, length in an axial direction is decreased, and the size and the weight of the pump are reduced to a value lower than those of a conventional type.

Title: Explosion release structure for tank
Inventor: OZAKI MASAHIKO
IPC: B65D90/02
Filed: 1995-02-10
Abstract: PURPOSE: To provide an explosion release structure for a tank, capable of controlling a position where a roof of the tank is bursted and a position where the bursted roof is blown off. CONSTITUTION: A stainless steel sheet 12 is welded to a portion of the periphery of a tank roof 4, and this stainless steel sheet 12 is welded to a stainless steel layer 11 formed by padding welding on a flange part 5a provided at the upper end of a tank side plate 3, thus sealing the tank roof 4. By this method, the strength of the stainless steel sheet portion is made lower to release explosion, while corrosion can be prevented by utilizing stainless steel. Further, a wire 13b for connecting the roof 4 to the side plate 3 is mounted on the opposite side of the explosion release portion of the roof 4, thereby controlling the movement of the roof in the case where the roof 4 is blown off by explosion.  With this arrangement, the outflow of a stored liquid in the tank due to breakage of the whole tank, a welded part between the bottom plate and the side plate, etc., which is caused by explosion, can be prevented, whereby a secondary accident can be prevented from occurring.

IPC: H04L12/58
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To realize a function of executing service processing with respect to an access terminal via a public line network by priority. SOLUTION: In this messaging processing method, in order to execute a processing process 10 corresponding to an access terminal 15-17 used via a public line network by priority, identifiers (10a, 6a, 7a) denoting 'prioritized processing' are provided in management tables (10, 6, 7) of the processing process. A dispatch processing program 5 of a messaging server 1 executes the processing process with the identifiers denoting the 'prioritized processing' by priority when deciding which processing process to be executed, that is, in the case of process dispatch processing.  Since the processing of the access terminal connecting to the public line network is conducted by priority, even when a user uses the messaging processing system from a visited place or other outside place on business trip, the service equal to or more than the service in the case of using the access terminal connecting to a conventional LAN is served.
