Title: Turbine rotor blade connecting device
Inventor: SAITO EIJI
IPC: F01D5/22
Filed: 1988-10-14
Abstract: PURPOSE:To prevent the subject device from cracking and breaking of a connecting member due to vibration stress with locally intensive load decentralized into surface pressure by inserting an air spring into the shroud connected portion of adjacent rotor blades. CONSTITUTION:Adjacent rotor blades 3 have their tips provided with shrouds 4 at an approximately right angle to a radial direction. Then, the shrouds 4 have protrusions 1a, 1b so formed that pressure from the next blade end is made into compressive load. So, an air spring 2 is inserted into a gap 10 due to the level difference in a radial direction of the protrusions 1a, 1b. Intensive transformation load due to vibrational stress can be thus distributed and degraded so as to avoid breakages and cracks without collision of the connected portion of the rotor blades 3.

Title: Resolver position detecting circuit
Inventor: TANIMOTO TOMOAKI
IPC: G01B7/00
Filed: 1986-10-31
Abstract: PURPOSE:To excite a plurality of resolvers using one exciting circuit, by forming a signal synchronous to one of two-phase exciting signals and setting said signal to the initial value load signal of each detection counter. CONSTITUTION:A waveform shaping circuit 81 converts an exciting signal EA of a sine wave to a pulse P1 having a duty cycle of 50% and synchronous to the exciting signal EA and a load signal generating circuit 82 converts said pulse P1 to a pulse P2 and further converts the pulse P2 to an inversion pulse P3. An AND gate 823 inputs the pulses P2, P3 and outputs a pulse P4 having the same pulse width as the cycle of the clock CKb of a counter 2b to the count er 2b as an initial load signal. Since the pulse P4 is synchronous to the exciting signal EA, the counter 2b is synchronous to the exciting signal EA. Therefore, even when the clocks CKa, CKb of counters 2a, 2b are different, common excita tion becomes possible.

Inventor: FUJI KAZUO
IPC: B65H29/52
Filed: 1987-10-14
Abstract: PURPOSE:To effectively prevent the periphery of a rotor from being damaged by a paper peeling edge by optionally reciprocating a weight for exciting and abutting the paper peeling edge on the periphery of a rotor along a guide groove. CONSTITUTION:The weight 11 for exciting and abutting the paper peeling edge (e) on the periphery of the rotor is optionally reciprocated along the guide groove 34. When an excessive load is applied to the tip side of a paper peeling claw 33 by paper stuck to the peripheries of the rotors 24, 27, the claw 33 is separated from the peripheries of the rotors and freely oscillated, so that the peripheries of the rotors 24, 27 can be prevented from being engaged with the edge (e). When the claw 33 is slightly rocked, the value of the weight W applied to the claw 33 is extremely reduced, so that the rock of the claw 33 is reduced. Thus, the generation of paper jam or accordion jam between the claw 33 and the peripheries of the rotors 24, 27 can be prevented and the peripheries of the rotors can be prevented from being damaged by the paper peeling edge.

IPC: H01P3/127
Filed: 1990-09-28
Abstract: PURPOSE:To realize an inexpensive and small sized mode converter with simple structure by connecting a circular waveguide, a circular coaxial waveguide and a circular waveguide in series. CONSTITUTION:A circular coaxial waveguide 2 is constituted by providing an outer guide 10 and an inner guide 11 coaxially and the inner guide 11 consists of two parts, a cone part and a cylinder part. The TE01 mode sent in a circular waveguide 1 is converted in the TE01 mode in a coaxial waveguide by the coaxial waveguide 2, and the TE01 mode in the coaxial waveguide is converted into a mixed wave comprising the TE01 mode and the TE02 mode at a connecting part 12 between the coaxial waveguide 2 and the circular waveguide 3. Since the length of the circular waveguide 3 at the lower stream part is selected properly, a phase difference of both the modes at its cut section is 180 deg.. Since the circular coaxial waveguide easily manufactured is used in place of a swell waveguide being a partial mode converter in this way, highly accurate and complicated processing is not required and the inexpensive mode converter is obtained.

Abstract: PROBLEM TO BE SOLVED: To prevent the choking of medium, channels by preventing the adhesion of scales and catching of fibers forming seamless ribs lengthwise on the heat transferring surfaces of heat transferring plates and supporting plates with the seamless ribs between the plates. SOLUTION: Lengthwise seamless ribs 13A are formed on the heat transferring surfaces 11A of heat transferring plates 10A. When the heat transferring plate 10A is laminated on top of the other reversing it, the supporting points S3 between the plates form a lengthwise continuous line, no protrusions that catch fibers or on which scales adhere are formed in the medium channels and the choking or the adhesion of the scales can be prevented. As the height of the medium channels between the plates are secured to be the twice of the shaping depth of the ribs 13A and the cross sections of the medium channel are without drastic increase or decrease of them compared with those of the conventional one, the solid scales pass them easily and the choking of the medium channels is prevented.
