Title: Logic circuit device
Inventor: ISHIHARA FUJIO
IPC: G06F3/00
Filed: 1996-10-09
Abstract: PROBLEM TO BE SOLVED: To prevent transmission delay and transmission waveform noise from increasing and suppress the size of an output buffer by detecting potential variation on a wire and operating a potential variation transmitting means only when the potential variation needs to be transmitted. SOLUTION: If potential variation is caused at a node A1, the potential variation at a node B1 having passed through a delay circuit 4d becomes a waveform which is delayed by a certain time. An exclusive OR circuit 4e computes a coincidence comparison between signals of those two nodes A1 and B1 to obtain a signal Z1 which is at 'H' level for a certain time when the potential variation is caused at the node A1. With this signal Z1, a tri-state inverter 4a becomes active only when the potential variation is made at the node A1, but enters a high-impedance state when not. When the tri-state inverter 4a is active, a signal sent out of a macro logic circuit 1 is transmitted through the wire 3b to reach a macro logic circuit 2.

Title: Automatic valve
Inventor: TSUTSUI OSAMU
IPC: F16K31/40
Filed: 1988-10-24
Abstract: PURPOSE:To have large movement of a main valve body with a small amount of expansion and contraction using a simple construction by furnishing a valve body to open and close a pilot valve hole at one end of a lever, installing a piezo element at the other end of lever, and by expanding and contracting the piezo element by means of piezo-electric impression. CONSTITUTION:A pilot valve body 29 opening and closing a pilot valve hole 24 is installed at the tip of a level L with different level lengths l1, l2. This level L can tilt up and down round a fulcrum 35 situated approx. in the center of the shorter edge of the lever body 32 while its longer edge 33 is kept horizontal. A piezo element 30 is installed below this fulcrum 35. This piezo element 30 is expanded and contracted by means of piezoelectric impression, and even its small amount of expansion and contraction opens and closes the pilot valve hole 24 to a great extent with the aid of the pilot valve body 29 round the fulcrum 35, that leads to opening and closing of a main valve body 17. Thus a large motion of main valve body 17 is achieved by a small amount of expansion and contraction of the piezo element 30.

Title: Method for stabilzing mechanism system to be controlled in positioning control system
Inventor: HAMAMATSU HIROSHI
IPC: G11B21/10
Filed: 1989-10-18
Abstract: PURPOSE:To improve the damping property of a mechanism system to be controlled, and to stabilize the system by using a filter composed of the parallel circuit of a notch filter and a band pass filter. CONSTITUTION:A filter 5 composed of the parallel circuit of a notch filter 2 and a band pass filter 4 is provided between a control system 1 and a mechanism system 3 to be controlled.

Title: Utilization of calculated truss form
Inventor: YASUHARA SUMIO
IPC: E04B1/19
Filed: 1997-08-15
Abstract: PROBLEM TO BE SOLVED: To simplify assembly and repair inspection by a method wherein the semiperiphery or more of a bolt is locked by welding between a bolt part and a form material when a veneers are locked by a bolt in a lateral direction, a vertical direction, and a plane in and on which the veneers are laid, in a truss assembly, wherein a member is obliquely placed in a square or an oblong outer frame. SOLUTION: The plane of the outer periphery of a frame member uses an L-steel, channel steel, a square pipe or the like but when the L-steel is used, a high angle part is in an out state, and a coupled surface forms two sides of the one being a plane side part and the other being a linear side par at one side. The two surfaces are used in a coupled state, the surface of the plane side is coupled with a linear side and coupled with the L-steel. When the two sets are coupled together, an object having a square outer periphery and being high is formed, and a type to mutually assist weakness of a plane is formed. Even during stacking period where the objects are stuck, a part forming a support surface situated below is wider than the under surface of an upper member.  This is because more outer periphery is locked by welding and an excellent product is produced even when arts are not kept with a situation. Thus, simple assembly and repair inspection are practicable.
