IPC: F16C17/06
Filed: 1993-09-21
Abstract: PURPOSE:To provide such a tilting pad thrust bearing that has large oil film pressure and enlarges bearing load capacity.

Title: Incoming signal generating device
Inventor: MIZUGUCHI SHINICHI
IPC: H04M19/04
Filed: 1987-09-18
Abstract: PURPOSE:To miniaturize capacitors for a transformer and to lower a ripple voltage by operating the transformer of a step-up circuit at a high frequency. CONSTITUTION:A switching signal generating part 12 receives a high frequency signal sent from a high frequency signal supplying part 13 and an incoming frequency signal sent from an incoming frequency supplying part 14, and generates a switching signal as the logical product of them. A step-up part 11 generates the high frequency signal by the switching signal, and generates a high voltage DC signal by boosting by the transformer 41. Furthermore, a discharge part 15 performs the discharge and absorption of a high voltage signal by synchronizing with the incoming frequency signal, and generates an incoming signal at a telephone set 16. Thus, since the transformer of the step-up part 11 is operated at the high frequency, it is possible to miniaturize the transformer, and it is not required to prepare the capacitor 43 large in capacity for lowering the ripple voltage.

Title: Production of standard sample for laser emission spectrum analysis
Inventor: TANIMOTO WATARU
IPC: G01N21/63
Filed: 1992-09-02
Abstract: PURPOSE:To enable stable analysis not generating the segregation of a standard sample and eliminating the damage of an optical system due to scattering at the time of the irradiation with light by a method wherein a solution to be analyzed is absorbed into a water-absorbable substance and this substance is dried to form the standard sample for forming a calibration curve. CONSTITUTION:A solution to be analyzed is absorbed into a water absorbable substance and this substance is dried to form a standard sample. Therefore, the sample is uniformly dispersed in the water-absorbable substance and there is no fear of generating the concn. distribution (segregation) of an element to be measured at all and the damage of an optical system due to scattering is not generated even at the time of the irradiation with laser beam. For example, when the solution to be analyzed with known concn. prepared by precisely weighing Al and Te is compared with a sample formed from molten Zn to which Al and Te are added in the same concns. by a rapid coagulation method, irregularity is reduced to a large extent because there is no segregation in the sample. Since an accurate calibration curve can be used, a stable analytical result is obtained.

Title: Radio communication system, method for hand-over and radio repeater
Inventor: ISHIGURO TAKAYUKI
IPC: H04W16/26
Filed: 1999-08-23
Abstract: PROBLEM TO BE SOLVED: To enhance the hit rate of hand-over by extending retrieval time for a radio base station by a radio repeater on the occurrence of the hand-over. SOLUTION: When a radio repeater 20 requires hand-over (202), the radio repeater 20 transmits a hand-over instruction 1 to a radio terminal 10, stops communication with the radio terminal 10 and retrieves a radio base station being the destination of the hand-over to conduct synchronization of LCCH (203, 204). Then the repeater 20 transmits the communication channel previous to the hand-over to the radio terminal 10 to set up a communication channel (205, 206) and transmits a hand-over instruction 4 to the radio terminal 10. Upon the receipt of the hand-over instruction 4, the terminal 10 conducts usual dial connection. Thus, a communication channel between a radio base station 30n which is a hand-over destination, and the radio repeater 20 is set up (207), the radio terminal 10 receives an LCH assignment signal 3 and the communication is made possible (208).
