Patent JP-H0336695-A (JP)
Title: Visual range state detecting device
Inventor: KUDO KATSUHIRO
IPC: E01F9/658
Filed: 1989-07-04
Abstract: PURPOSE:To detect the visual range of daytime by finding out visibility distance based upon the ratio of brightness values of two recognition plates drawn by white and black. CONSTITUTION:Image information including two recognition plates 12, 13 drawn by white and black is stored in a multi-level image memory 33 through a television camera 31 (11) and an A/D converter 32. As to the recognition plates 12, 13, the size of the plate 13 is larger than that of the plate 12 so that the number of picture elements on a screen is identical in both the plates 12, 13. A brightness ratio calculating part 34 segments the areas of the plates 12, 13 from the memory 33 and finds out the brightness ratio of white and black parts in respective plates 12, 13. A visibility distance calculation part 35 finds out a visibility distance from the brightness ratio of the two plates 12, 13 and the set interval between the plates 12, 13. When the output of the calculation part 35 is shorter than a previously set visibility distance, a visual range validity deciding part 36 outputs an invalid visual range decision to the post stage, while outputting a valid visual range decision in the other case.

Title: Subscriber circuit of terminal device exclusive for incoming call
Inventor: ASAKURA JIYUNJI
IPC: H04Q11/04
Filed: 1981-10-26
Abstract: PURPOSE:To store an existing terminal exclusive for incoming call into a time division switchboard without reconstruction, by controlling a current supplying circuit with the output of an AND of the negtive conditions of a control line for reduction of power consumption and the affirmative conditions of a control line for the current supplying circuit. CONSTITUTION:A control program of a central processing controller 11 drives both a power consumption reduction control line 6 and a current supplying circuit control line 7 when a terminal T is free. Thus a general subscriber terminal SUB has an originating call, and this call is detected by a loop monitor circuit 5 if a short circuit is secured for the DC resistance between lines A and B. For a subscriber circuit 12 of the terminal exclusive for incoming call, a current supplying circuit 4 is controlled with the output of an AND circuit 13 of the negative conditions of the line 6 and the affirmative conditions of the line 7. Thus the circuit 4 of the circuit 12 is turned off although the control program drives the lines 6 and 7 when the terminal is free and regardless of a general terminal or the terminal 12 exclusive for incoming call. As a result, no current is supplied even with a connection of the terminal T short-circuited between the lines A and B in the normal mode. Thus it is avoided that a loop is detected by the circuit and then regarded as an originating call.

Title: Balancer device for engine
Inventor: MATSUMOTO YASUO
IPC: F16F15/26
Filed: 1989-07-05
Abstract: PURPOSE:To reduce the rolling moment of an engine by selectively controlling the operation of two balancers arranged separately in the direction of the central axis of a cylinder depending upon the operating condition of the engine so as that when one of the balancers is rotated the other balancer is stopped to rotate. CONSTITUTION:The balancer device of an engine 19 is constructed so as that when the rotation rate of the engine 19 is smaller than a specified value a low rotation balancer 16 is rotated and a high rotation balancer 15 is stopped to rotate, and when the rotation rate of the engine 19 exceeds the specified value the high rotation balancer 15 is rotated and the low rotation balancer 16 is stopped to rotate. Thereby the position of the balancer is practically displaced in the direction of the central axis of the cylinder, that is equivalent to displace the position of the balancer in the direction of the central axis depending upon the operating condition of the engine 19, thus the rolling moment can be reduced significantly in wide operating condition even in operation range of low velocity high load or high velocity low load.

Title: Continuous furnace
Inventor: TATE SETSUO
IPC: F27B9/36
Filed: 1989-06-28
Abstract: PURPOSE:To permit the securing of a given quality by a method wherein the title furnace is provided with a transfer means, transferring a matter to be projected, a plurality of projecting bodies, projecting the matter to be projected, and an approaching and separating means, approaching and/or separating a distance between each matters to be projected. CONSTITUTION:The relation of vt=1 is established among the time interval (t) of projection, the speed (v) of a transfer means 2 and a distance (1) between matters 4, 4 to be projected. A controller 10 transmits a driving signal to a shaft driving device 7 and operates the distance (i) from a received speed signal based on the above- mensioned formula. In this case, when the time interval (t) of projection is determined from projecting conditions required by a matter 3 to be projected, the value of the distance (1) may be obtained in accordance with the change of the speed (v). The controller 10 converts the distance, obtained in the controller 10, into the number of rotation of a shaft 11 for moving the matter to be projected and when a shaft rotating number signal, received from a counter 9, has arrived at an equal rotating number, the controller transmits a drive stopping signal to the shaft driving device 7 to stop the same. As a result, the shaft 11 for moving the matter to be projected is turned by only a necessary rotating number and is retained thereafter.

Next, in the closure fitting state of the frame bodies 12, 40, the dangling edges 26, 52 are opposingly provided in approximation, so a face side is reduced, and the appearance of the room inside is improved.  As a result, framing can be carried out with precision, and the labor of site work can be saved, and the surfaces of a ceiling board and an inner lid slab can be constructed approximately evenly.
