The lower voltage in the signal voltages of the input signals XA1 and XA2 is outputted as the output signal YA. When the signal voltages of the input signals XA1 and XA2 are identical, the voltage is outputted as the output signal YA. That is, at least one of the input signals XA1 and XA2 which are inputted to the AND gate 1 is '0', the output signal YA becomes '0'. When both input signals XA1 and XA2 are '1', the output signal YA becomes '1'. When the input signals XA1 and XA2 are the combination of 'NIL' and '1' or 'NIL' and 'NIL', the output signal YA becomes 'NIL'.

Title: Opening/closing mechanism for folding door
Inventor: TAMAOKI YOSHIHARU
IPC: E05D15/26
Filed: 1993-02-26
Abstract: PURPOSE:To improve usability by a method wherein a moving end during opening of a folding door is separated away from a opening surface and the opening angle of the folding door is increased by specifying the moving locus of the moving end of a folding door through engagement of a roller at the arm free end of a moving body with a guide groove. CONSTITUTION:A support end is pivotally mounted on one side edge of an opening, a moving end is moved along an opening through a roller 10 engaged with a guide groove 5, and a folding door 2 is folded back for folding double to open a door. In this case, rollers 9 and 10 are arranged to the free end of an arm 8 pivotally mounted on a moving body. Further, in a guide groove 5 during opening of the door, a tongue piece 15 is resiliently deformably arranged to an end part on the side where the rollers 9 and 10 are positioned in a direction in which the width of the groove 5 is increased. Thus, the moving ends of door plates 2a and 2b are separated away from the guide groove 5 to the outside and the opening angle of the door 2 is increased. A rotation moment in a door closing direction is exerted on the hinge mounting parts of two door plates 2a and 2b folded back during full opening, and a press force is exerted on the rollers 9 and 10. This constitution causes application of a component of a force in a door closing direction on the moving ends of the door plates 2a and 2b by means of a reaction force and development of the door 2.

Title: Method for rolling extremely thick steel plate excellent in internal quality
IPC: B21B15/00
Filed: 1992-03-19
Abstract: PURPOSE:To cancel the restriction of rolling reduction due to a temp. drop in the tip and tail end parts of a steel plate and to obtain the steel plate excellent in the internal quality by preliminarily drawing down the tip and end part of the steel plate before executing finish rolling pass. CONSTITUTION:At the time of manufacturing an extremely thick steel plate and when finish rolling pass after completing broadside rolling is executed, the tip and end part are preliminarily drawn down before executing the finish pass. When one pass to five passes of the five final passes of finish rolling after completing broadside rolling are executed, the tip and end part of the steel plate is preliminarily drawn down extending over the length L=30-500mm before executing these passes. Rolling reduction DELTAh=h1-h0 at the time of preliminary drawing down is not especially stipulated, but it is preferable to take the rolling reduction as large as possible to fully display the effect of preliminary drawing down. In this way, the center porosity of the steel plate is efficiently rolled and the internal quality can be improved.

Abstract: PURPOSE:To construct an expanded anchor in a large cross section in a correct position in an optional area by expanding a hole with high-pressure jet water ejected from a high-pressure water ejection rod. CONSTITUTION:Drilling is made to a specified depth with a drilling rod, and a casing in a part corresponding to an anchorage part on the front end of the drilled hole 1 is extracted. Then, a high-pressure water ejection rod 2 is inserted from the inside of a casing positioned in a free length part on the tail end of the drilled hole 1 until it reaches the front end of the anchorage part. The rod 2 is then extracted little by little while high-pressure water is ejected from the front end of the rod 2 to the surroundings with a high-pressure plunger pump, and the ground surrounding the drilled hole 1 is cut with the high-pressure water and an expanded hole 3 is made thereby. Then, the drilling rod is inserted into the drilled hole 1 until it reaches the front end of the hole, and cleaning is made inside the drilled hole 1 with mud discharged by running of water. A tension steel is inserted into the drilled hole 1 and an anchorage body is constructed with grouting 4 made under pressure either to the expanded hole 3 in the anchorage part or the drilled hole 1.

Title: Novel light guide
Inventor: SHIMIZU TADASHI
IPC: G02B6/12
Filed: 1988-03-18
Abstract: PURPOSE:To facilitate connection to optical fibers by laminating the polymer of a 2nd photosensitive resin on the polymer of a 1st photosensitive resin and making the refractive index of the latter higher than the refractive index of the former. CONSTITUTION:The polymer 2 of the 1st photosensitive resin is laminated on a base 1 and the polymer 3 of the 2nd photosensitive resin thereon and the refractive index of the latter is made higher than the refractive index of the former. The combination of the 1st photosensitive resin and the 2nd photosensitive resin is satisfactory if the refractive index of the polymer 2 of the 1st photosensitive resin is lower than the refractive index of the polymer 3 of the 2nd photosensitive resin. While the combination is not particularly limited, the combination in which photolithographic characteristics, particularly sensitivity and developing characteristics are analogous are more preferable in case of simultaneously executing a photolithographic process. The connection stage is thus simplified by adequately selecting the film thicknesses of the respective layers in case of butting the end faces of light guides 2, 3 and optical fibers 4, 5 and connecting the same.

Title: Signal switching method
IPC: H03K17/00
Filed: 1992-03-19
Abstract: PURPOSE:To prevent noise generated when a signal with a large level difference is switched. CONSTITUTION:A switching switch which selects the position of a signal Vf when a switching signal Vg of, e.g. 5V is received and selects the position of a signal Ve in other cases is adopted for the switching of two kinds of the input signals Vf, Ve. A switching signal Vg is applied to the switching switch in a pattern whose time interval is gradually extended by (1/8)T each, and an output signal Vg is changed gradually from the signal Ve before the switching into the signal Vf after the switching by giving properly an output of the switching switch to an LPF. Thus, even when a level difference between the signals Ve and Vf is large, the generation of noise when the signals Ve and Vf are selected by the switching switch is prevented.
