Title: Reset circuit
Inventor: NISHITANI KAZUHARU
IPC: H03K17/22
Filed: 1984-11-07
Abstract: PURPOSE:To reset surely a connected internal circuit without malfunction by detecting a point of time when an input signal increased gradually exceeds a transition voltage after this point of time so as not to be decreased to the transition voltage or below. CONSTITUTION:When a reset input voltage 5a gets higher than the transition voltage VTR of an inverter 1, an output voltage 1a of the inverter 1 is inverted to an L level. Since an FET 7 is turned from off to on, the inputvoltage 5a rises at a time constant depending on a resistor 2, a parallel resistor with the FET 7 and a capacitor 3. Thus, the leading of the input voltage 5a is quickened after the input voltage 5a exceeds the voltage VTR. Even if the input voltage 5a is changed pulsively, it does not reach the voltage vTR or below. Through the control above, the connected internal circuits 6a-6n are reset surely without malfunction.

Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of unnatural display with few memories by separately compiling and storing the objects of a near view and a distant view, varying only the direction of eyes, displaying the far view, initializing a buffer, varying the position of a viewpoint and the line of the sight and synthesizing the near view object. SOLUTION: Data on the positions and the forms of the three-dimensional objects in the near view and the distant view are separately compiled and are stored in respective storage parts 101 and 102. A layout compiling part 104 comprising CPU and a three-dimensional graphic compiling program calls a selected by a mode selection part 103, fixes the position of the viewpoint, varies only the line of the sight and displays the distant view on a display 113. Then, the buffer is initialized, the distant view object is set to be the furthest, the position of the viewpoint and the line of the sight are varied and the near view object is displayed and synthesized. Thus, the display position of a background can be prevented from being greatly changed although a user moves the eyes only by a slight distance.

Filed: 1993-09-24
Abstract: PURPOSE:To provide a pipe joint for a water pipe bridge having such bending rigidity that it is not bent by the external load while giving a predetermined bending angle to a pipe line. CONSTITUTION:A bent groove 46 is constituted between the sides of groove width adjusting rings 42, 44 only by fitting a pair of groove width adjusting rings 42, 44 in an annular groove 40 formed on the outer periphery of an insert port 38. The tapered surfaces of divided pieces 48a, 48b, 48c formed by dividing the section are made contact with the bent groove 46 so that a lock ring 48 is engageably in the inner periphery of a socket. The divided piece 48b is pushed inward radially by a set bolt 50 to reduce the diameter and thereby the lock ring expands the whole width by the action of the tapered surface along the whole width of the bent groove 46. Thus, the socket 30 and insert port 38 are firmly joined together to give a required bending angle between these axes.
