Title: Output buffer for mos semiconductor integrated circuit
Inventor: SHIMADA HAJIME
IPC: H03K19/00
Filed: 1987-07-09
Abstract: PURPOSE:To reduce the energy dissipated as an electromagnetic wave by controlling a driving element by OR between an output voltage threshold value and an input so as to relax the steep change in the output voltage waveform. CONSTITUTION:Threshold circuits 11, 16 having threshold values VT1,VT2 having an output voltage and OR circuits 12, 14 controlling both driving elements 13, 15 are provided. Then the control ON period a2 of the high potential driving element 13 is a period from a change point of an input terminal voltage till an output terminal voltage reaches the VT2 or the like and the control ON period a3 of the low potential driving element 15 is a period from other change point of the input terminal voltage till the output terminal voltage reaches VT1 or over by driving the threshold circuits 11, 16. That is, at the start of rise/fall of the output waveform, both the elements 13, 15 are turned on to apply an intermediate voltage to the output load. Thus, steep change in the output voltage waveform is relaxed.

Title: Method for repairing radial tire
Inventor: SAITO OSAMU
IPC: B60C13/00
Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To suppress strength decrease and fatigue of ply cord at a side protrusion and recess site even in the case of aging use by adhering a reinforcing material to an inner surface side of a tire at the side protrusion and recess site. SOLUTION: When an external damage or rubbed damage occurs at a side of a carcass layer 6 of a radial tire 1, a protrusion and recess A (side protrusion and recess site A) is locally generated at its part. This occurs due to that a ply cord 5 is plastically deformed. Thus, a reinforcing material 11 of a patch-like state is adhered to an inner surface side of the tire of the side protrusion and recess site A with adhesive to be reinforced. As the material 11, repairing patch sold in the market is used, formed of rubber, and embedded with many rayon cords 12 at an interval therein. The cords 12 are disposed in its axial direction toward a tire radial direction, and adhered. In this case, tension of the cord 5 is loaded particularly to the cords 12 to alleviate tension loading of the cord 5, thereby suppressing progress of strength decrease and fatigue.

Two comparators 10 are connected to each preamplifier 11, and they are switched to the sampling mode and the holding mode by clocks phi1 and phi2 respectively. Signals phi1 and phi2 have 180 deg. phase difference. Outputs of comparators in the first system whose mode is switched by the signal are connected to a code converting circuit 21, and those in the second system whose mode is switched by the signal phi2 are connected to a code converting circuit 22, and they are converted to digital outputs. Thus, AD conversion is performed with effectively two-fold conversion frequency while keeping the shortening effect of a recovery lime tgamma of comparators 10 due to amplifiers 11.

Filed: 1984-08-21
Abstract: PURPOSE:To prevent troubles such as crystal defects from occuring from a etched lower edge portion of a lower layer, by making the edge portion a non- acute angle. CONSTITUTION:An resist film 7 and an upper layer 1 of a member to be etched consisting of the upper layer 11 and a lower layer 2 are taper-etched.

Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To provide an MCP(microchannel plate) and a secondary electron amplification device that can provide high secondary electron amplification, with a simple structure. SOLUTION: A layer of a secondary electron emission metal 14 is formed on the inside wall of each taper-like thin tube 13 of which emission side has a small diameter, and incident electrons 12 collide against the secondary electron emission metal 14 and are multiplied so that secondary electrons 15 are emitted as emitted electrons 16.

Abstract: PURPOSE:To increase the quality of a fibrous diaphragm, by transposing the fiber layers accumulated to the paper making mesh in the 1st and 2nd transposing processes and drying the fiber layers accumulated to the forming mesh by the warm air after a pressing process at the normal temperature. CONSTITUTION:For making of paper, the fibers suspended in the water are accumulated to the paper making mesh in the same way as conventional, and the 1st transposition is given to the fiber layers accumulated to the paper making mesh to the transposition mesh. Then the 2nd transposition is carried out to shift the fiber layers accumulated to the transposition mesh to the forming mesh. During these processes of transposition, the lumbrical swells produced in the paper making process can be eliminated in a natural way. After this, the fiber layers accumulated to the forming mesh are pressed by the nonheated metal mold of normal temperatures, and the pressed fiber layers are dried by the warm air. In this way, a fibrous diaphragm can be obtained with a light weight, a high rigidity internal loss and excellent homogeneity.
