Title: Liquid crystal constituent body, manufacture thereof and input-response type optical modulator
Inventor: FERGASON JAMES LEE
IPC: G02F1/13
Filed: 1992-02-28
Abstract: PURPOSE: To maintain precise tolerance over large surface area by fluidly connecting individual volumes in a medium to one another. CONSTITUTION: In the liquid crystal structure which generates a 1st optical response unless a prescribed input is present, orients a liquid crystal substance in response to the prescribed input, and generates a 2nd optical response, the liquid crystal substance is in a confinment medium and individual volumes in the medium are connected fluidly to one another. Namely, some capsule 22 is sometime not linked to other capsules 22, but another capsule 22 can be linked to >=2 other capsules 22 by one or >=2 paths 200. The mutual linkage can be made continuous or substantially continuous in, for example, a layer 34, or made discontinuous. Whether a path 200 is present or absent is considered to depend upon a method and/or conditions for manufacturing a capsule sealed liquid crystal substance and/or a method and/or conditions for arranging it and the layer 34.

Title: Magnetic recording and reproducing system
Inventor: YOSHIDA TEIJI
IPC: G11B20/14
Filed: 1979-07-23
Abstract: PURPOSE: To accurately reproduce the digital data, by obtaining the reproducing pulse through the use of preceding pulse at the production of consecutive pulse within a given period forming the pulse in response to the peak distortion of analog waveform of reproduced digital signal.  
     CONSTITUTION: When the digital signal (a) stored in tape is reproduced, it becomes the analog signal of waveform b. Further, the head detection circuit 3 produces the window pulse corresponding to the specified level α to the peak value to prevent the apparent peak detection of the low level of the waveform (b), and the sawtooth wave (e) having the half width of the cycle 2T of the signal (a) in response to the logical product of the peak detection pulse (d) of the peak pulse generating circuit 4, is fed to the reproducing pulse generating circuit 5. If the pulse (f) produced in response to the leading of the sawtooth wave (e) by this circuit 5 is generated consecutively between the cycle 2T, the preceding pulse is selected and the reproduced digital signal is formed, allowing to accurately reproduce the digital data, even with the delayed leading and trailing of the pulse (c) with greater distortion of the waveform (b).

Title: Demodulator
Inventor: SUMINO AKIRA
IPC: H04L27/22
Filed: 1989-04-14
Abstract: PURPOSE:To prevent an error from being enlarged even when the error is generated in a transmission line by detecting a frame signal determined in advance between transmission and reception, calculating symbol difference between the transmission and reception from the detected frame signal and reproducing received data according to this symbol difference. CONSTITUTION:A frame detector 41 executes the synchronization decision of the frame signal, which is determined in advance between the transmission and reception, from a demodulation signal 39 and only when the frame signal is detected, a signal '1' is supplied to a computing element 43 as a frame synchronizing signal 47. The computing element 43 estimates the symbol difference between the transmission and reception from the frame synchronizing signal 47 and the symbol train of a signal inputted to each shift register and supplies symbol difference signals 49a-49c to a code converter 45. The code converter 49 executes the code conversion of the demodulation signal 39 based on the symbol difference signal. Then, received data 51a-51c are reproduced. Thus, even when the data are erroneously received, the error is not enlarged but the data can be received with high quality.

Title: Semiconductor switch
Inventor: UDA NAONORI
IPC: H03K17/693
Filed: 1993-04-20
Abstract: PURPOSE:To improve the insertion loss characteristic of a high frequency signal by providing a 2nd FET between a gate of a FET receiving/interrupting the high frequency signal and a ground potential and controlling an ON-resistance of the 2nd FET to control the attenuation of the signal passing through the FET thereby reducing a length of a transmission path through which the high frequency signal leaks. CONSTITUTION:With a voltage of 0V given to a gate voltage terminal 13 and a voltage of 3V given to a gate voltage terminal 14, a FET 10A is turned off and a FET 10B is turned on. Thus, a high frequency signal RF is not outputted to an output terminal 11 but outputted to an output terminal 12 through the FET 10B and given to a circuit of other system (not shown). When a voltage at a gate voltage terminal 15 gets higher, an ON resistance of a FET 10C is decreased and a gate voltage applied to the FET 10B is decreased. Thus, the ON resistance of the FET 10B is increased, the signal RF passing through the FET 10B is attenuated and a signal level at the output terminal 12 is decreased. Thus, no attenuator is required and the leaked signal is reduced.

Title: Transistor switching circuit
Inventor: AMAMI HIDEYUKI
IPC: H03K17/61
Filed: 1980-07-11
Abstract: PURPOSE:To obtain extremely sharp switch-on characteristics and switch-off characteristics by supplying a reverse bias current between the base and emitter of a transistor when a forward bias current is cut off. CONSTITUTION:When a switch S2 is turned on, a bias current rising extremely fast is supplied to the base and emitter of a transistor TR1 via a diode RE1 and a capacitor C1, so the TR1 shows excellent switch-on characteristics. When the switch S2 is turned off, on the other hand, magnetic energy accumulated in a reactor L1 while the switch S2 is on  is discharged via its secondary winding to flow a reverse bias current between the emitter and base of the TR1. Since this current rises extremely fast and is large, the TR1 shows extremely sharp switch-off characteristics with little insulation recovery delay due to the Hall effect.
