Title: Adjusting mechanism for shape of mirror surface of parabolic antenna reflector
Inventor: UEHA MASAZUMI
IPC: H01Q15/16
Filed: 1989-08-17
Abstract: PURPOSE:To increase the degree of freedom of adjustment by fitting a wire to both ends of a lever member respectively and selecting an optional point between mount points as a point to be adjusted so as to vary the displacement and the radius of curvature independently. CONSTITUTION:The mechanism consists of a lever member 7 and two wires 10, 11 the wires 10, 11 are fitted to both ends 8, 9 of the member 7 and a midpoint '0' of the mounding points is selected so as to agree with the point on a structure member 1 for an object of the adjustment. Assuming the mounting point as the point to be adjust 12, then tension of the two wires is given independently, and the principle of lever is used to vary the resultant force in two directions at the point 12 and the moment caused around the point 12 independent. Thus, it is possible to vary the displacement of the point 12 and the radius of curvature by using the dynamic relation of the force, displacement, moment and radius curvature. Thus, the displacement and radium of curvature of the wire are varied independently by giving not only the force but the moment to the wire, thereby increasing the degree of freedom of the adjustment.

Abstract: PURPOSE:To prevent deterioration of printing quality and false selection due to rotary variation of a type drum by a method wherein a damping mechanism for suppressing vibration of a type group is provided and spring component coming in pressure contact with the damper wheel. CONSTITUTION:A damper wheel 53 is energized in the direction significant digit by a damper spring 54, in form of a leaf spring having central hole, inside a type drum 3. In a printer of a system in which the type drum 3 is mechanically and compulsority stopped or compulsorily driven, vibration or rotary variation is generated generally when the type drum 3 starts of stops. The damper wheel 53 and the damper spring 54 act as a damping mechanism for reducing such vibration or rotary variation. When selection behavior of the type drum 3 being no damping mechanism is shown, bouncing just after the type drum 3 stops is decreased by adding damping mechanism, and rotary variation just after the type drum 3 is driven again is settled. When difference in angular velocity occurs, frictional torque occurs on a contact surface between the damper wheel 53 and the type drum 3.

Title: Measuring method for refractive index distribution of base material of optical fiber
Inventor: NAKAYAMA SHINICHI
IPC: G01M11/00
Filed: 1990-08-11
Abstract: PURPOSE:To prevent drawing even immediately after a sintering stage and enable highly accurate measurement of a refractive index distribution by converting a detection signal of a light receiver to pulse signals and taking out only a pulse signal corresponding to zero order among the signals. CONSTITUTION:First a detection signal of a light receiver 16 is passed through a differential circuit 32. If the detection signal contains components 41', 42' of high order diffraction light on both sides of a component 40' of zero order diffraction light, the detection signal after differentiation 32 comprises pulse signals 41'', 40'', 42''. These are generated tau1, tau0, tau2 hours after a chopper 14 generates a reference signal, respectively. The differential circuit 32 can vary settings according to rotation frequency of the chopper 14 and can differentiate signals of desired frequency. That is, all diffraction light generated by straie can be sorted and desired zero order diffraction light can be taken out among them. Thus time tau0, since the chopper 14 generates the reference signal until a pulse of the zero order diffraction light is generated is obtained. Then from time tau0, a refraction angle theta can be obtained by calculation to obtain refractive index distribution.

Title: Selective excitation method of nuclear spin in mri apparatus
Inventor: TAKEUCHI HIROYUKI
IPC: G01R33/565
Filed: 1991-07-31
Abstract: PURPOSE:To eliminate artifact and reduce image pickup time significantly by applying a second gradient magnetic field after the excitation of a nuclear spin by a first high-frequency pulse while a second high-frequency pulse is made to irradiate a first nuclear spin for further excitation. CONSTITUTION:Firstly, a slice-way inclined magnetic field GS1 is applied while a 90 deg. RF pulse with a specified band width is applied. Then. the slice-way inclined magnetic field is applied with an inclination of GS2 different from the value GS1. As a result, nuclear spin is excited by 180 deg. inside slice planes 31 and 33 inside an examine 1 so that the nuclear spin in the slice plane 31 is excited by 270 deg. in total. On the other, as the nuclear spin within the slice plane 33 is not yet excited, it is excited only in the direction opposite (180 deg.) to that of a magnetostatic field and, hence, no signal is outputted from the nuclear spin. The nuclear spin in the slice plane 32 subjected to an excitation by 90rt. angle, not by 180 deg. and no echo signal is produced. Thus, only the desired slice plane 31 alone can generate a spin echo signal.
