Title: Electric wire
Inventor: SUKEGAWA TAKASHI
IPC: H01B5/10
Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To improve lay ratio and prevent wind noise, corona noise, and snow accretion trouble by constituting with a core member having a plurality of almost straight-shaped grooves in the long direction and conducting members engaged with the grooves of the core member. SOLUTION: A core member 1 is made of a material capable of forming in a wire-like body of several hundreds meters or more, is the wire-like body having a square or hexagonal cross section, and grooves 2 are formed at the corners. A conducting member 3 is made of a copper wire and engaged with the groove 2 of the core member 1. In the production of an electric wire, since the wire-like body is not intertwisted, an intertwisting process is made unnecessary, and since the conducting member 3 is engaged with the core member 1 almost in a straight line, lay ratio is almost 1, and the amount of the conducting member 3 used is minimized. Since the cross section is non-circular, generation of Karman's vortex is prevented.  Snow on an electric wire can not rotate along the ply of the electric wire because the conducting member 3 is not intertwisted and the outer surface forms a recessed and projecting surface, and falls down without growing into cylindrical snow.

Title: Pressure display method
Inventor: MURATSUBAKI RYOJI
IPC: G01L19/08
Filed: 1986-07-04
Abstract: PURPOSE:To make display easy to look and to judge the abnormality of pressure variation, by a method wherein the specific values of varying pressures are alternately displayed when the pressure of a fluid system of which the pressure varies frequently is displayed and direct display is performed at the time of abnormality. CONSTITUTION:Pressure variation during sampling times T1 is always measured and a pressure drop ratio N0 is compared with preset drop confirmation quantity N1 and, when N1>=N0 is obtained, drop confirmation pressure Pd is detected. Next, after a time T2, return pressure Ps is compared with the aforementioned confirmation pressure Pd and, when Pd<=Ps is obtained, it is judged that pressure return is performed normally. In this case, pressure Pd<=Ps is alternately displayed. When pressure is not returned to stable pressure Ps by the generation of abnormality and pressure does not drop because closure is generated in a fluid system, the above mentioned alternate display is stopped and the pressure of the fluid system is displayed as it is.

Title: Data transmission control system for loop transmission system
Inventor: TADA MASAHIRO
IPC: H04L12/433
Filed: 1980-11-11
Abstract: PURPOSE:To eliminate a specific master controller and to reduce the overhead, by providing a timer which is reset to an initial value with each passing of the frame information, on each of plural data transmitters. CONSTITUTION:Each of plural data transmitters 2 connected to loop transmission line 1 (1-IN and 1-OUT) carries out a relaying action when it acquires no right for transmission. The signal sent from the line 1-IN is demodulated by a demodulating circuit 20, and the data and the clock are delivered to signal lines 101 and 102 respectively. A selector circuit 40 selects either the relaying action or the transmission of data for the transmitter 2, and this circuit 40 is controlled by a control circuit 50. The circuit 50 continues the timing while a request is produced for transmission and contains a timer which is set to the initial value with each detection of the transmission right frame. Then the specific frame information is transmitted when the timing value of the timer exceeds a certain value. This frame information makes a round of the transmission line and is detected at the receiver side to acquire the right for transmission.

Title: Copying device
Inventor: KOGURE MASAAKI
IPC: G03G15/04
Filed: 1985-07-18
Abstract: PURPOSE:To finish a graphic original, etc., in soft tone so as to be easily visible without patching a screen by installing a bag-like body subjected to white screen processing on a pressure plate and setting the dot density of the white screen within a specific range. CONSTITUTION:The bag-like body 4 is installed on the surface of the pressure plate 2, and the original O to be subjected to a white dot screen can be attached and detached out of said bag-like body 4. The white screen processing, that is, white dot screen processing is applied on the outer surface of said body 4, and the density of the white dot of the screen is 4-8/mm, which means high density compared with a conventional density of 2-3/mm. The reason why to do so is that the density approximates the critical resolution of a copying device in the range of a space frequency of 4-8/mm. As a result, the density becomes higher, and a density drop will not occur, because a white dot is smeared in a black character and a black painted part.
