Title: Three-dimensional measuring apparatus
Inventor: MIYAZAKI HARUOMI
IPC: G01B11/24
Filed: 1991-07-15
Abstract: PURPOSE:To heighten the computing operation speed. CONSTITUTION:A projector 4 is so installed as to position the light source point 5 in the X-axis of spatial coordinate axes and at the same time a solid picture picking-up camera, a solid picture picking-up device 3 is built therein, is so installed at the origin of the spatial coordinate axes as to agree the Y-axis of the spatial coordinate axes and the optical axis 8. When light is emitted from a projector 4. the light comes in to the surface of a measurement object 1 set in the space coordinate axes and the image of the measurement object 1 at that time is shot on the light radiated surface 7 of the solid-state picture picking-up device 3 in the inside of the solid-state picture picking-up camera 2 and the analog quantity is converted into digital quantity by an analog-digital converter 9. Further, the digital quantity is computed by a digital computing operation apparatus 10 of a central processing apparatus 11 and thus the computing operation like this is carried out for every scanning beam while the emitting angle of the light is successively changed by the projector 4 controlled by the central processing apparatus 11 and consequently, three-dimensional shape of the measurement object 1 is measured.

Title: Polyarylate
Inventor: HOSOI BUNPEI
IPC: C08G63/195
Filed: 1989-08-01
Abstract: PURPOSE:To prepare a polyarylate having a compatibility or suitable reactivity with nylon and excellent in alloying with nylon by specifying the limiting viscosity and absorption peak in the infrared spectrophotometry of the polyarylate. CONSTITUTION:A polyarylate which is obtd. from bisphenol A, isophthalic and/or terephthalic acid, and an acid anhydride, and has a limiting viscosity of 0.35-0.80 and a ratio of the absorbance of the absorption peak (obtd. by infrared spectrophotometry) at 1800cm<-1> to that of the absorption peak at 1740cm<-1> of 0.0005-0.02. A limiting viscosity [eta] lower than 0.35-0.80 gives the polyarylate inferior in physical, mechanical, and chemical properties including otherwise excellent heat resistance. A value of [eta] higher than the above range, being too high, decreases the flowability and excessively elevator the m.p. and molding temp., thus making the polyarylate unsuitable for alloying.

Abstract: PROBLEM TO BE SOLVED: To provide a simple and highly reliable junction structure by using a stud bolt of welding to secure the junction between the almost center part of a reflecting plate and the underframe of a large parabolic antenna. SOLUTION: A stud bolt 90 of an Al alloy is attached by welding to the back side of a reflecting plate 1 of an Al alloy almost at its center part 12. Then the bolt 90 is jointed to an underframe by a nut 90', via a hole 32 of a junction part 31 of an anti-vibration reinforcing plate 3 added to an inner frame 21 of the underframe.

Thus, the plate 1 can be used for a long period of time. In addition, there is no concern that such a contact corrosion, due to different types of metals, to occur at the antenna since both plate 1 and bolt 90 are made of an Al alloy.

Title: Original scan controller of image forming device
Inventor: TAKANO MASAHARU
IPC: H02P29/00
Filed: 1983-10-26
Abstract: PURPOSE:To simplify a speed-frequency converting circuit by using a phase- locked loop circuit as the control circuit of an electrophotographic copying mahine which converts a drum rotating speed and an optical system scanning speed into frequencies and taking a variable magnification copy by varying the ratio of the both. CONSTITUTION:The output A of a drum rotating speed detector 52 is converted into a pulse wave B by an element 57 which generates pulses of frquency corresponding to an input voltage. When the pulse wave generated by dividing the frequency by 64 through a frequency divider 58 and by N through a frequency divider 59 leads the output A in terms of phase, the output of a phase comparing circuit 5 drops and the input to a voltage-controlled oscillator 57 drops to decrease the frequency of the pulse wave B. When the pulse wave lags to the contrary, an adjustment is made similarly, so the B has a frequency 64N times as high as that of the A. This is controlled in proportion to the frequency obtained by the output of a scanning speed detector 64 into pulses, and a scan is made synchronously with the rotation of a drum.

Title: Transformer
Inventor: OGURA YASUHIRO
IPC: H01F27/28
Filed: 1983-10-28
Abstract: PURPOSE:To facilitate the insulation of the low voltage side transition wire of an up- down-allotted coil from the high voltage leads by a method wherein the leads drawn out of the upper and lower ends are arranged on the opposite side of the lead drawn out of the winding center with respect to a core, and are drawn out by penetration through a core window in the neighborhood of the upper or lower end of the winding after gathering together. CONSTITUTION:The leads 14a and 14b on the upper and lower yoke sides of the high voltage winding are led out to the opposite side of the high voltage lead 13 with respect to the core 10. After these leads 14a and 14b on the yoke side are connected up and down by means of the transition wires 15 on the elad-out side, the low voltage elad 30 is penetrated through the neighborhood of the high voltage winding in the core window at the yoke side end and thus drawn out to the same side with respect to the high voltage lead and the core. Thereby, since the transition wires of the leg I and the leads 13 do not come to proximity, troubles in insulation are not generated between both the wires. Besides, since the potentials at the opposed parts of the lead 30 and the high voltage winding become equal by making the position of penetration of the lead 30 into the core window in the neighborhood of the yoke side end of the high voltage winding, there exists no problem with respect to insulation, thereby enabling leading out through the core window.
