Inventor: OBARA AKIRA
IPC: G01B21/06
Filed: 1998-05-13
Abstract: PROBLEM TO BE SOLVED: To provide measuring equipment of ware elongation amount of a link chain which can accurately measure wear elongation amount between chain links during operation, not only in the normal time but also in the case deflection is caused in the link chain, and measuring equipment for the method. SOLUTION: Tow noncontact system laser displacement gauges 3a, 3b are arranged above a link chain 2. By using the gauges 3a, 3b, an isolation distance as far as the link chain upper surface is continuously measured, and the wear elongation amount between chain links is measured. Measured data are inputted in a CPU 6 serving as a recording means and an operating means with which a CRT is connected, through electric cables 4a, 4b and controllers 5a, 5b. When data indicating deflection of the link chain are contained in the measured results by the laser displacement gauges, data values are corrected in a true chain link length. As a result, it is preferable that a deflection correcting means is installed in the operating means constituting the measuring equipment.

Title: Small-sized dc motor
Inventor: MURAKITA WATARU
IPC: H02K1/22
Filed: 1988-05-26
Abstract: PURPOSE:To prevent a rotor from vibrating in its axial direction by providing means for differentiating axial magnetic attraction force generated between a magnet and a core at both sides with respect to the center of its axial width. CONSTITUTION:The centers of the axial widths of a magnet 11 and a core 21 are substantially brought into coincidence. The shape of the magnet 11 is formed in a plate state bent in a cylindrical surface state in such a manner that the circumferential width is wider toward a commutator 3. According to this configuration, the magnetic resistance of a passage in which the magnetic flux of the magnet 11 passes through the core 22 becomes smaller toward the commutator 3. Thus, the magnetic flux density of the left side section from the center of the axial width becomes higher, an attraction force toward the commutator 3 is generated at the core 21, and the end face of the rotary shaft 20 of a rotor 2 is pressed to a thrust receiving plate 7. Accordingly, the rotor 2 is not axially vibrated at the time of rotation to prevent a noise from generating.

Title: Optical module, and method for setting optical isolator position
Inventor: OGUSU MAKOTO
IPC: G02B7/00
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To easily set an optical isolator position by engaging an optical isolator in an opening for being placed and fixed. SOLUTION: An optical isolator 1 is arranged at a position between a 1st lens 3 and a 2nd lens 4 where light becomes approximately parallel. A light emitting part fixing a 2nd lens block 6 of a module case 5 has two steps of inner diameters, and the module case 5 has a larger inner diameter which is slightly larger than an outer diameter of the optical isolator 1. The optical isolator 1 is engaged in the diameter up to the step of the smaller diameter and fixed by laser welding or soldering. For this fixing, since an optical axis is set in the opening, a position adjustment is not required in a plane vertical to the optical axis but a fine adjustment is performed by turning the optical isolator one round. Since the opening of the light-emitting part guides the turning of the optical isolator 1, this permits an easy turning adjustment centering the optical axis.

IPC: G02B6/12
Filed: 1982-07-29
Abstract: PURPOSE:To perform stable on-off operation free from electromagnetic induction by irradiating the light beam having the wavelength in a visible to IR region onto a broken photoconductive path thereby heating the same. CONSTITUTION:The light beam 8 emitted from a light source 5 is reflected by a mirror 6, is stopped down by a lens 7 and is irradiated onto the gap of a photoconductive path 2 having a high refractive index. The wavelength of the beam 8 is preferably in a visible light to IR region which is vulnerable to absorption as heat and LiNbO3 or the like of which the refractive index is increased by temp. elevation is preferably used as the element having the photoconductive path. The gap part is heated by the irradiation of the light beam, then the temp. in said part rises and the refractive index increases, thus forming the part 2 of the refractive index higher than the part 1 of a low refractive index around the same. The passage of the light in the gap part is thus permitted while the light is irradiated thereto.

Title: Dc power unit
Inventor: MORITA KOICHI
IPC: H02M3/28
Filed: 1987-05-28
Abstract: PURPOSE:To keep current balancing at a stable state and to supply a constant voltage to a load, by correcting a reference voltage to be supplied from a reference voltage source to first and second error amplifiers so as to set a current detected in a current detection circuit at a desired ratio. CONSTITUTION:The reference voltage is corrected so as to keep the current balancing without performing voltage control and current balancing control with two separate control loops. In other words, the first and second error amplifiers 17a and 17b are always set at operating states in spite of a current balancing state, and both first and second voltage control circuits go to states to decrease their output voltages (load voltages) when the output voltage is increased. Adversely, when the output voltage is decreased, both the first and second voltage control circuits go to the states to increase their output voltages. In such a way, it is possible to prevent the remarkable fluctuation of the ratio of the current arrotment of the first and second voltage control circuits, that is the current balancing state, from being generated, and to accelerate response speed in the current balancing control when the output voltage is fluctuated.
