Title: Self-supporting type optical cable
Inventor: KUME SHINICHI
IPC: G02B6/44
Filed: 1981-12-29
Abstract: PURPOSE:To prevent a decrease in transmission characteristics and the breaking  of a wire even when side pressure operates during laying operation by stranding  a cable obtained by embedding optical cores in a cable sheath at an internal and in parallel around a messenger wire. CONSTITUTION:The optical cable body 14 is formed by arraying optical cores 16A and 16B provided with fiber-reinforced plastic coatings around the optical fibers in parallel and at an interval and then covering them with a sheath 18 of nonadhesive thermoplastic plastics such as polyethylene. The optical cable  body 14 is wound around the messenger wire 12 while stranded repeatedly. Since  ther is no relative shifts occurring between the optical cores 16A and 16B, and cable sheath 18, neither a decrease in transmission characteristis nor the breaking of the wire occurs even when side pressure operates during laying operation.

Abstract: PROBLEM TO BE SOLVED: To obtain a method or structure for easily preventing the lateral shift of a nonmagnetic spacer being inserted between the lower surface of a plunger and a ferromagnetic plate for supporting the plunger on the lower surface thereof in an electromagnet. SOLUTION: In place of a conventional method for preventing lateral shift of a spacer by fastening the spacer to a supporting plate by means of screws, a new method is employed for preventing lateral shift of a spacer by fitting the spacer in any one component of electromagnet except the spacer 7. For example, a flat recess is made in the upper surface of a supporting plate 6a and the spacer 7 is fitted therein.

Title: Oil returning device of internal-combustion engine
Inventor: YAMAKAWA TOORU
IPC: F01M1/06
Filed: 1981-12-28
Abstract: PURPOSE:To improve the returning of oil at high speed running, by utilizing pulsating pressure generated in a crank chamber to forcibly return the oil to an oil pan respectively from a rocker chamber and the crank chamber. CONSTITUTION:At operation of an engine, positive pressure and negative pressure of a piston 6 at its vertically reciprocating motion are all acted upon a crank chamber 3 to remarkably cause generation of pulsating pressure. Accordingly, at operation, forcible returning of oil in a rocker chamber 13 at negative pressure then forcible returning of oil in a recessed part 21 of a partitioning plate at positive pressure are alternately repeated synchronously with the pulsating pressure in the chamber 3. Then with a period of the pulsating pressure in the crank chamber, forcible returning action of oil is changed in accordance with a speed of the engine, at high speed running, if a lubricating oil quantity is increased, a large amount of oil can be forcibly returned meetably to the above increase.

IPC: G09G3/18
Filed: 1988-08-27
Abstract: PURPOSE:To facilitate an accurate read of data on a display means visually by inputting data per unit time set by a setting means previously to an arithmetic means and finding their mean value. CONSTITUTION:When the unit time for calculating the mean value of measurement data is determined optionally, inputted, and set from a key input box 18 as the setting means, a CPU 34 inputs data from an A/D converter 32 corresponding to the set unit time and the arithmetic means processes them to find their mean value. Then an LCD is made opaque by a quantity through a driver circuit 36 corresponding to the percentage of the mean value to a specified voltage until a next mean value is calculated. Thus, the mean value is displayed on the display means 10 and then a shift in the position of the opaque LCD at the tip end indicating the mean value can be varied optionally, so the mean value can be read sufficiently with the human eyes.

The conformity with the quantized road map is evaluated while moving the traveling orbit in parallel within this area. The position having a high evaluation value is set as the position of a candidate road having the possibility of the present position. Whether the candidate road is conformed with the actual road is evaluated to determine the final position. When the candidate road can not be finally narrowed to one, the minimum area including all candidate roads is displayed. When no candidate road is present, only the present position existing area is shown to an user, whereby reliability is kept.

Title: Superconducting array display device
Inventor: KATAOKA TERUO
IPC: G11C11/44
Filed: 1988-08-29
Abstract: PURPOSE:To hold magnetic field information completely by one-time writing by generating a written loop current in a loop film made of a superconducting material and generating a magnetic field pattern with the current. CONSTITUTION:A stationary current is written or not written by picture elements in superconducting loop films 24 arrayed in a matrix on a magnetic field array substrate 20 to generate the electric field pattern. A luminous flux control element 21 which is controlled corresponding to the magnetic field array pattern turns on and off luminous flux by the picture elements to control the quantity of transmission of the luminous flux 22. The state of the element 21 is determined according to whether or not there is a magnetic field, so once a permanent current is written in the loop film 24, an invariably light-dark pattern can be displayed. Consequently, the magnetic field array pattern of complete memory performance is realized with the permanent current of the superconducting loop film and a complete still image display device can be realized only by writing an input signal once without using any refresh memory.

Title: METHOD OF FORMING Ib-IIIb-VIb2 COMPOUND SEMICONDUCTOR LAYER AND MANUFACTURE OF THIN-FILM SOLAR CELL
Inventor: WATANABE TAKAYUKI
IPC: H01L31/04
Filed: 1999-07-28
Abstract: PROBLEM TO BE SOLVED: To enable an Na-containing CuInS2 layer formed on an Mo electrode through a thermal treatment method to hardly separate from the electrode and to enhance a thin-film solar cell, equipped with an Na-containing CuInS2 layer as a light absorbing layer in conversion efficiency. SOLUTION: An In thin film 3, a Cu thin film 4, an Na2S thin film 5, and an InS thin film are successively formed on an Mo electrode layer 2 in this sequence for the formation of a Cu-In-Na layer 7. Then, this laminate is thermally treated in an H2S gas atmosphere, by which a Na-containing CuInS2 layer 8 is formed. At this point, although an NaInS2 phase 9 is produced on the CuInS2 layer 8, the NaInS2 phase 9 is removed by depositing a CsS layer on the NaInS2 phase 9 through a solution growth method, in a case where a solar cell is formed. A solar cell obtained by this method is higher in conversion efficiency than that obtained through a conventional method, where the Na2S thin film 5 is formed just over the In thin film 3, and the CuInS2 layer 8 is enhanced in adhesion.

Next, mutual information quantity I(thetai) is calculated by using the threshold dividing table. Then, an attribute threshold thetan' is obtained to lead out the maximum value of the mutual information quantity I(thetai) and by this attribute threshold thetan', a dividing table to describe the class condition of a training example to be sectioned is prepared. The mutual information quantity is calculated in each attribute and the attribute to show the largest mutual information quantity is allocated to a next low order node. Thus, the classifying tree is generated.
