Title: Isostatic molding method for titanium powder
Inventor: HORITANI TAKAO
IPC: B30B11/00
Filed: 1993-11-11
Abstract: PURPOSE:To drastically reduce the production cost in the case of molding with conventional urethane molds by using an inexpensive mold material and controlling a cold isostatic pressing(CIP) medium temp. in CIP molding of titanium powder. CONSTITUTION:This isostatic press molding method for titanium powder comprises composing the molds for powder molding by using a thermoplastic resin having >=30 deg.C of thermal deformation temp., TD deg.C and setting the medium temp. TM deg.C of CIP higher by 10 deg.C than the TD deg.C at the time of molding the titanium powder by CIP. As a result, the high-density CIP molding free from 'crack' equiv. to the conventional moldings is produced by using the inexpensive thermoplastic resin molds without using the costly urethane molds used heretofore. The production cost of the titanium powder metallurgical products is thus drastically reduced.

Title: Signal processing method of phase-modulation optical fiber gyro
Inventor: SHIMIZU RYOTARO
IPC: G01C19/72
Filed: 1991-10-29
Abstract: PURPOSE:To reduce the activating time of an optical fiber gyro by shortening the adjusting time of phase. CONSTITUTION:A phase difference DELTAtheta of synchronous signals is optimized so that P becomes maximum by measuring a phase difference output Pproportional cos (DELTAtheta) related to a modulating component in the interfering output and the phase difference DELTAtheta. In this case, the measuring range is first set to be -pi<=DELTAtheta0<pi. It is checked whether or not DELTAtheta0 is -pi/2(b) or pi/2(a), and if so, the phase difference DELTAtheta0 is specified as -pi/2 or pi/2. The phase is optimized based on the specified value. If not, the measuring range is shifted to narrow -pi/2<DELTAtheta1<pi/2. The maximum value of the output P is searched. If there is the maximum value, DELTAtheta1=0 is held and therefore the phase is optimized. If DELTAtheta1not equal to 0, the measuring range is shifted to -pi/4<DELTAtheta2<-pi/4. P is measured in this range to obtain the maximum value. Every time P is measured, the measuring range is sequentially narrowed to pi, pi/2, pi/4.... Accordingly, the number of times of measurement can be remarkably reduced.
