Title: Laminating material for multilayer printed wiring board
Inventor: TAKE MORIO
IPC: H05K1/03
Filed: 1988-06-06
Abstract: PURPOSE:To obtain substantially the same value of dielectric characteristics even when the ratio of the quantities of a reinforcing base material and a resin by composing the base material and the cured thermosetting resin or the thermosetting resin after curing of substances respectively having the same dielectric constant substantially. CONSTITUTION:Each dielectric constant of a base material (a reinforcing base material) and a cured thermosetting resin or a thermosetting resin after curing is equalized practically. Consequently, a method in which the dielectric constant of the base material is made the same as that of the cured thermosetting resin or the thermosetting resin after curing substantially is used normally, but a method in which the dielectric constant of the cured thermosetting resin or the thermosetting resin after curing is equalized practically to that of the base material may also be employed inversely. A woven fabric in which two kinds or more of base materials having different dielectric constants are compounded is used as the base material in order to adjust the dielectric constant of the base material. Accordingly, a desired dielectric characteristic value can be held even when the quantity of the resin among each layer of an internal layer board employed for multi-layer laminate molding, a prepreg for bonding, a single-side metallic-foil clad board for an external layer, a copper foil or the like is changed.

Title: Operating command preparing method for robot
Inventor: SANO MASATOSHI
IPC: G05D19/02
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To suppress vibration in a normal mode when repeating acceleration and deceleration are repeated at a short pitch. SOLUTION: A constant velocity area is forcedly provided between an acceleration area from time t0 to time t1 and a deceleration area from time t2 to time t3. Since no acceleration/deceleration is generated in the constant velocity area, external force is not operated to a robot and even when the robot is operated repeatedly in a period close to the period of vibration in a normal mode, the generation of the vibration in a normal mode can be suppressed.

Title: Positioning device
Inventor: AIHARA TAKASHI
IPC: G05D3/12
Filed: 1988-06-06
Abstract: PURPOSE:To eliminate an unnecessary shock when deceleration starts by selecting the output of 2nd arithmetic means and switching the arithmetic means to a 1st arithmetic means at the moment when the output values and their time-differentiated values of the 1st and 2nd means respectively become equal to each other. CONSTITUTION:An adder 6b is inserted to the input of an operator 52 for con trol rule and the origin of the function f2 of a control rule 2 is shifted by the adder 6b by X0. The X0 is decided so that function f1 and f2 can osculate with each other and the control rule is switched at the point of osculation, because an unnecessary shock is eliminated, but the acceleration as well as the velocity become continuous at the switching point. Since the adder 6b is added to the input of the arithmetic operator 52 in order to add the constant X0 for shifting the origin of the function f2 so that the functions f1 and f2 of control rules 1 and 2 can osculate with each other, X* and X* become continuous at the switching point of the control rules 1 and 2. Thus unnecessary shock can be eliminated.

Filed: 1980-10-03
Abstract: PURPOSE:To bring a phase error to necessary value or lower by a method wherein a connecting pin of a substrate unit formed by mounting a semiconductor magnetosensitive element to a printed wiring insulating substrate is projected from a core gap and arranged, and fitted where being hardly subjected to an effect of magnetic flux. CONSTITUTION:The connecting pins 8 connecting drawing wiring to the outside are mounted to the thin substrate unit 7 shaped by printing drawing wiring onto the insulating substrate and fitting the Hall element 3 to the wiring. The substrate unit 7 is projected from the core gap only by a distance l, and a loop 9 of the connecting pins 8 is formed where being hardly subject to an effect by leakage flux phil. Accordingly, since the magnetic flux density Bl of the leakage flux phil aroung the core gap suddenly decreases when the distance l increases, induction electromotive force is also minimized, and the phase error caused by the electromotive force can be reduced. The production of the current transformer having the predetemined phase error is enabled by selecting the distance l.

Title: Apparatus for detecting phase image using heterodyne-detecting light receiving device
Inventor: ICHIMURA TSUTOMU
IPC: G01J9/00
Filed: 1990-05-28
Abstract: PURPOSE:To ensure the accurate detection of the phase image of a body having the phase difference in a broad range by synthesizing sample-transmitted light and reference light having the different frequency, detecting the phase distribution of the sample beat component in the one-dimensional direction or the two-dimensional direction along the sample, obtaining the phase image of the sample, and separating the image from incoherent light. CONSTITUTION:Measuring light I having a frequency omega1 and light I' having a frequency omega2 which is slightly different are combined by a half mirror HM. Photoelectric conversion is performed in a detector D. Only the component of the difference omega1 - omega2 is made to pass a band BPF, and only the AC component is taken out. When the amplitude is constant, the signal having the frequency DELTAomega, the phase phi1 - phi2 and the constant magnitude is obtained from the filter F. In the expression, phi1 is the phase of the measuring light I. The phase is changed depending on the refractive index and the thickness of a body Ob which is inserted into a light path. The phase represents the phase of the body. The phase phi2 of the local oscillated light I' has the value of the constant reference. Therefore, the phase of the body Ob can be detected by measuring the phase of the AC signal obtained from the receiver HD.
