IPC: H03K3/3562
Filed: 1997-11-19
Abstract: PROBLEM TO BE SOLVED: To eliminate the need of using a differential amplifier for substituting an input differential signal for two logic levels by permitting specified sample- and-hold units to simultaneously amplify series signal samples. SOLUTION: A clock circuit 2 is composed of a clock and 2n-pieces of delay elements which are connected in series to the output of the clock. When the series signal has the period T, a clock signal is selected so that the delay of T/2 is generated by the clock and the delay element having the period nT. The first delay element can be programmed. For restoring the edge of the clock signal combined with the series signal, a control signal CD operates on the delay element which can be programmed and the edges of the clock signals CK1-CKn; CK'-CKn' are advanced or delayed. A logic processing/judgment circuit 3 estimates whether the edges of the signals CK1-CKn; CK1'-CKn' are to be advanced or delayed from the sample obtained by the output of the ample- and-hold unit.

Title: Liquid crystal display device
Inventor: NAKANO MINORU
IPC: G02F1/1368
Filed: 1994-12-24
Abstract: PURPOSE: To prevent the light drop-out by a reverse tilt discrination without making respective pixel apertures smaller which are to be effective pixel regions by overlapping pixel electrodes via insulating layers on the wirings of a substrate and forming slits for preventing the infiltration of the reverse tilt discrination in the outer parts of these pixel electrodes. CONSTITUTION: The points where the reverse tilt discrination arises are parted from the centers of the pixel electrodes 3 by overlapping the pixel electrodes 3 via the insulating films 13 on the wirings 4. Further, the slits 14 for preventing the infiltration of the reverse tilt discrination are formed at the pixel electrodes 3 in the positions corresponding to the outer side of the pixel openings 6. The infiltration of the reverse tilt discrination into the inner side is prevented by these slits 14. Then, the parts where the light drop-out arises are limited near to the wirings 4 and the narrowing of the width of a mask layer 5 to shut off the light to the light drop-out part is made possible and the light transmittance is enhanced by widening the openings 6 of the respective pixels.

Title: Data transmission method and device
Inventor: WESTON DAVID ROBERT
IPC: H04L29/08
Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To surely transmit data to a certain destination from a plurality of data transmitting sources by using a common data channel. SOLUTION: Information items which occur at a plurality of data transmitting sources 25-28 are transmitted to a data destination 9 as a series of data packets through a common data channel. Each data packet is separated from the preceding and succeeding packets transmitted from the same data transmitting source by a prescribed cycle period while the cycle period of each data transmitting source is different from each other. Each information item is repetitively outputted from the same data transmitting source as at least N pieces of continuous data packets (N is the number of data transmitting sources).  Since the optimum cycle period 'period n' of the n-th data transmitting source is expressed by an equation, Period n=2x 'burst period' x(N-1)<2> +n (where, 'burst period' is a parameter about the length of the data packet), it is guaranteed that at least one of the above-mentioned N pieces of continuous data packets arrives at the destination 9 without overlapping the data packets from other data transmitting sources.

Title: Travel carriage for installing sheet laying carriage
Inventor: KIKUI KEIZO
IPC: E21D11/38
Filed: 1993-12-28
Abstract: PURPOSE:To keep the axial line of a travel carriage loaded with a sheet laying carriage in agreement with the axial line of a primary lining segment. CONSTITUTION:The actual axial center O' of a guide frame front end periphery 4a is calculated on the basis of a gap between a guide frame front end periphery 4a and a primary lining segment inner wall 1a inputted from many touch sensors 63 and 66 laid on guide frame front end peripheries 4a and 4b. Thereafter, the deviation of the actual axial center O' from the proper axial center F' of the periphery 4a saved in a processor 66 is divided into a deviation (x) along a horizontal direction and another deviation (z) along a horizontal direction for calculation. Then, an instruction is issued to a hydraulic power unit 68 on the basis of the calculation result, thereby extending a front horizontal swing cylinder 54 by a distance corresponding to the deviation (x). Concurrently, a front elevator cylinder 52 is expanded by a distance corresponding to the deviation (z). The alignment of the guide frame front end section is thereby completed. Also, the rear end section 4b of the guide frame is similarly aligned.

Title: Sheet material cutting device
Inventor: KASHIWAGI IWAO
IPC: B26D1/20
Filed: 1990-11-30
Abstract: PURPOSE:To recover a sheet material cutting device in the failure state easily or automatically to an original state by moving a circular blade in the pressure contact direction between the circular blade and a fixed blade and in the direction away from the fixed blade when the circular blade is at a standby position at one end of the longitudinal direction of the fixed blade. CONSTITUTION:When a sheet material to be cut is erroneously put into a cutting part in plural or when a sheet material to be cut which is thicker and harder than usual is inserted, a repulsive force acting between a rail 2 and a fixed blade 6 is increased, and if resulted deflection exceeds an overlapping amount of a blade edge 7 of the fixed blade 6 and a peripheral edge of a circular blade 1, the circular blade 1 rides onto the fixed blade 6. However, the circular blade 1 can not be moved much because of a retaining ring 9 and it is moved to a standby position riding on the fixed blade 6. When a rod 10 placed at the standby position for pushing back the circular blade 1 is pushed in the direction shown by an arrow A in this state, the circular blade 1 is recovered to a normal state.

Abstract: PURPOSE:To obtain images of a required range with good quality by one time of image pickup by providing a deformed 8-shaped loop coil formed by coupling two deformed loops consisting of two loops, large and small, which are coupled to one, to an 8 shape and a deformed saddle-shaped loop coil facing the large loop. CONSTITUTION:The deformed saddle-shaped loop coil 2 is not oppositely disposed in the parts of the small loops 15, 16 of the 8-shaped loop coil 1 and, therefore, a sensitivity region is formed by the small loops 15, 16 alone and the shallow sensitivity region of a small effective relative sensitivity is obtd. Orthogonal magnetic fields are formed of the deformed saddle shaped loop coil 2 in the parts of the large loops 13, 14 and the entire part enclosed by the coil is the sensitivity region. The deep and large sensitivity region is thus obtd. The small loops are applied to the back from behind the neck of the person to be inspected. Since the neck from the head is inserted into the space of the large loop and the deformed saddle-shaped loop coil is inserted, the images of the backbone part up to about T6 over the entire part of the neck from the head are obtd. by one time of image pickup. Since the signals from the heart to entail the deterioration of image quality are not received, the image quality is improved.
