Title: Desk with wiring duct
Inventor: YOSHIDA RYUJI
IPC: A47B13/00
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To neatly house all wires inside a wiring duct even in the case that the large amount of the wires are used, to prevent the wires from being exposed and becoming the obstruction of a person passing by a desk and to easily perform a wiring operation without detaching a wiring cover further. SOLUTION: By sliding a cover body 13 forward, since the inner side face of a wiring space part provided inside a leg body 2 is largely opened and the large amount of cord kinds or the like pulled into the back surface side of a top plate 1 are neatly housed without detaching the cover body 13, the wiring operation is facilitated. Also, by opening the wiring space inward, even when the other desk or a partition or the like is present on the side face of this desk, the wiring operation is performed from the inner part of the desk without moving the desk.

Title: Embedding molding parts
Inventor: KAWAMOTO TAKASHI
IPC: B29B15/00
Filed: 1977-10-31
Abstract: PURPOSE: To prevent the outflow of the resin from the circumference of the metal fittings and to eliminate the burring in integrating the fittings inserted in the mold carity with a resin, by forming fin parts on the sides of the embedding strip fittings.  
     CONSTITUTION: The embedding metal fittings 4 are inserted in the entrance groove 3 of the mold 1, and the resin 6 is injected into the mold cavity 2 under pressure. The pressure of the resin 6 presses the fin pieces 5 which are brought into contact with the walls around the circumference of the entrance groove 3, thus preventing the outfloow of the resin 6 in the cavity 2 from the entrance groove 3.  
     EFFECT: Special mold accuracy and dimensions of embedding metal fittings are unnecessary. Short molding cycle results in low cost.

Title: Steam adjusting valve testing device
Inventor: KANEDA HIDEAKI
IPC: F01D21/00
Filed: 1982-07-30
Abstract: PURPOSE:To prevent the fluctuation of the output of a turbine at the time of testing the valve by a method wherein the lowering of the output of the turbine resulting from the closing of the steam adjusting valve at the time of testing the valve is detected, the opening degree of a remaining valve is increased to compensate for the lowering of the output and the testing valve is choked from its fully opened condition to its half- closed condition. CONSTITUTION:When a push button 1 for testing the steam adjusting vale is pushed down, a control section 2 transmits to a setting device 3 a signal designating the setting of an opening degree which is half the full stroke of the testing valve, the signal is compared to a signal from a valve opening degree detector 5 and the valve 8 is choked gradually to its half closed condition on the base of the difference between the above- mentioned two signals. At the same time, a control section 9 transmits a signal from a load setting device 10 to an output adjusting section 13 where the opening degree signal from the control section 2 is converted into a valve drive signal so that the adjust valve 15 which is not opened to the full is opened gradually to thereby compensate for the lowering of the output of the turbine due to the closing of the testing valve. In this case, the testing valve is choked only in a range from its fully opened condition in which a small output gain is produced with respect to the opening degree of the valve, to its half-closed condition.
