Title: Friction reducer
Inventor: YAMAOKA NORIHISA
IPC: F16M7/00
Filed: 1978-03-24
Abstract: PURPOSE: To facilitate the displacement of a stator frame, by providing an enclosed opening in the contact parts of a main body and a pedestal and providing a fluid inlet passage extending from the outside of the main body or the pedestal to the opening.  
     CONSTITUTION: When a fluid is introduced under pressure into the opening 9 through the fluid inlet passage 10 to adjust installation, the stator frame 20 on the opening 9 is pushed up by the pressure of the fluid so that the frictional force between the contact parts of the stator frame 20 and a bed 30 is reduced. Thus, a pushing force for displacing the stator frame 20 by a jack arranged between the stator frame 20 and a concrete foundation 6 can be decreased. As a result, the displacement of the stator frame 20 is facilitated.

Abstract: PURPOSE:To reduce the size and the cost of an optical integrated circuit by integrating a semiconductor laser and a photodiode formed on a cavity surface by a chemical etching method without using a cleaving method on the same semi-insulating substrate. CONSTITUTION:The N-type sides of a semiconductor laser and a photodiode are grounded, a positive voltage +V0 is applied to the P-type side electrode of the laser, and a negative voltage -V1 is applied to the P-type side electrode of the photodiode. The laser is oscillated by a current injected from the P-type side electrode of the laser, the light is emitted not only from the end of a front cavity, but also from the end of a rear cavity, and the light emitted from the end of the rear cavity is incident to the photodiode. Since a reverse bias -V1 is applied to the photodiode, a photocurrent flows proportionally to the light intensity. Accordingly, the intensity of the output light of the laser can be monitored by measuring the photocurrent.

Filed: 1993-01-29
Abstract: PURPOSE:To allow the highly accurate simultaneous measurement of curvature, outer diameter, and circularity of a tubular item by taking advantage of common points in the measurement of curvature and outer diameter. CONSTITUTION:A tubular item 1 to be measured is supported from below at two points separated from each other in the axial direction.

The distances L1, L2 from a reference point S on the outside of the item 1 to the opposite edges P1, P2 on the surface of the item 1 are then determined based on the scanning speed V and the scanning times T0, T1, T2. Outer diameter D and the distance L0 from the reference point S and the center 0 are determined based on the measurements L1, L2. Curvature of the item 1 is determined based on the maximum and minimum measurements of the distance L0. The circularity of the item 1 is determined based on the variation of outer diameter in the circumferential direction caused by rotation of the item 1.

Abstract: PURPOSE:To quickly retrieve an error occurrence location by storing a transmission data to a transmission data trace file and a reception data to a reception data trace file. CONSTITUTION:A transmission data and a reception data are stored sequentially in a transmission data trace file 21 and a reception data trace file 22 sequentially.

A trace file control means 12 reads a data in the transmission data trace file 21 or the reception data trace file 22 and is delivered to the input/output means 13 via the control means 11. The input/output means 13 displays the data on a display section 33. Thus, the error occurrence location is easily retrieved by observing the trace data displayed on the display section of the MODEM placed at both ends of the line 3.

Title: Constant-voltage power source circuit
Inventor: YONEDA SHIGEO
IPC: G05F1/575
Filed: 1983-03-02
Abstract: PURPOSE:To reduce external parts, and to incorporate them in an MOS-LSI circuit by controlling an ion resistance between a power source and a load by the first and the second MOS-FETs. CONSTITUTION:A load L1 and an MOS-FET M2 which becomes an on-resistance are connected to a power source, and this FET M2 is controlled so that load end voltage VDD becomes constant-voltage. When this FET M2 is controlled, the load end voltage VDD is detected by a volume VR1 provided in parallel to the load L1, and when the voltage VDD drops, a control voltage signal from a resistance R and an MOS-FET M1 is dropped (the potential of a point X becomes high) so as to raise said voltage, and as a result, a current between the source and the drain of the MOS-FET M2 does not flow easily. In this way, output voltage is stabilized. Also, this circuit is incorporated and formed in an MOS-LSI circuit.

Title: Method and structure for fixing optical fibers into grooves
Inventor: KAKII TOSHIAKI
IPC: G02B6/40
Filed: 1993-01-29
Abstract: PURPOSE:To realize the method and structure for fixing capable of fixing optical fibers into groove parts with high accuracy without subjecting the optical fibers to a special treatment. CONSTITUTION:The superposed body of a groove base plate 1, a foaming sheet 2 and an upper plate 3 is inserted into a protective pipe 4 and thereafter, the optical fibers 5 are respectively inserted into V-grooves by utilizing gaps 6 as shown in Fig. (A). The protective pipe 4 is then heated from its outside, thereby, the foaming sheet 2 is foamed and expanded as shown in Fig. (B). The volumetric change by the foaming pushes up the upper plate to eliminate the gaps 7. The foam, sheet 2 expands and intrudes into the gaps 6 while expanding, thereby individually pressing the optical fibers 5 into the bottoms of the V-grooves. Since the foam has adequate elasticity, adequate pressurizing force is imparted to the optical fibers 5.
