Title: Optical signal transmission system
Inventor: KATO MAMORU
IPC: G07D9/00
Filed: 1986-04-19
Abstract: PURPOSE:To transmit the additional information without deteriorating a train of main signal pulses by superposing the carrier wave undergone phase modulation via the additional information signal onto said pulse train. CONSTITUTION:A carrier wave generating circuit 1 produces a carrier wave B having low frequency compared a main signal pulse train A. Then the wave B is modulated by a phase modulating circuit 2 according to the additional information and superposed on a main signal via light emitting element 3 to be transmitted to an optical fiber 4. These superposed signals undergo light/ electricity conversion via a light receiving element 5 at the receiver side and are amplified by an amplifire 6. Then the main signal is separated by an HPF 7. While an LPF 8 separates the low frequency component and transmits a signal G. Then a phase discriminating circuit 9 discriminates the phase of the signal G and a pulse generating circuit 10 regenerates the additional information to transmit the additional information signal.

Title: Liquid crystal display device
Inventor: KOKUBO FUMIO
IPC: G02F1/133
Filed: 1996-04-11
Abstract: PROBLEM TO BE SOLVED: To reduce optical energy density abutted on a polarizing plate per unit time, unit area, to lower the temp. of the polarizing plate and to make it possible also to cool a liquid crystal panel by continuously moving the polarizing plate having the area larger than a light transmission part. SOLUTION: The polarizing plates 9, 11 are moved continuously so as to traverse the light transmission part within the range of involving the light transmission part. That is, as for two pieces of polarizing plates 9, 11 the plates longer than the liquid crystal panel 10 in the longitudinal direction are used, and they are held (fixed) movably vertically, and they are moved reciprocally vertically together. By such a manner, since the light energy density projected on the polarizing plates 9, 11 per unit time, unit area is reduced, the temp. of the polarizing plates 9, 11 is lowered.  Since the incident side polarizing plate 9 is brought at a high temp. particularly in a liquid crystal display part, the method that only the incident side polarizing plate 9 adapts a plate having the area larger than the light transmission part, and the temp. is lowered by reciprocally linearly moving it is applicable also.

Abstract: PURPOSE:To prevent consumption of battery by providing a control means for actuating a timer means upon detection of the start of charging operation and interrupting a switching means upon elapse of a predetermined time, and opening a circuit between the battery and a motor reel body upon completion of charging operation. CONSTITUTION:A motor reel comprises a switching means 45 for feeding/ interrupting power from a battery 46 to/from a motor reel body 12 side, a timer means 43 for measuring the charging time, and a control means 44 for actuating the timer means 43 upon detection of the start of charging operation and interrupting the switching means 45 upon elapse of a predetermined time.

Title: Detecting method for phase difference of interferometer
Inventor: MIHASHI YOSHINOBU
IPC: G01J9/02
Filed: 1985-04-25
Abstract: PURPOSE:To decide whether the polarity is positive or negative even when the range of a phase difference is expanded greatly by obtaining an envelope signal on which an interference signal of interference light consisting of plural known wavelength components is superposed. CONSTITUTION:The intensity of output interference light when coherent light beams which have wavelength lambda and are mutually phi out of phase is expressed as 2(1+cosphii). When this interference light output is superposed as to i=1, 2 and spectrum component of lambda1 and lambda2 are detected at the same time, the sum IT is as shown by an equation 1 and the difference is as shown by an equation 2; when phi1 and phi2 vary uniformly, the IT and ID draw what is called 'beat waveform'. Then, envelope outputs IHC and IHS of the equations 1 and 2 are as shown by an expression 3. A two-wavelength system using the equation 1 is judged within a range 0<=¦B¦<=pi on condition that envelope informa tion is obtained at the same time. Namely, the direction of variation is judged from ¦B¦, so the direction of variation is judged over a wide range without reference to the values phi1 and phi2 when phi1-phi2 is set small.

Abstract: PURPOSE: To bias so as to obtain a uniform potential distribution in a protective region and avoid an early stage breakdown by a method wherein a double capacitor chain having conductive regions which are buried in an insulating layer and provided above an epitaxial pocket - an insulating region junction is provided. CONSTITUTION: Rings 11 which define a 1st chain of capacitors connected approximately in series provide a linear potential distribution in the junction region of an insulating region 18 - an epitaxial pocket 8 and, by emptying gradually, a protective link 19 maintains a linear potential close to the distribution of the insulating region 18, so that the early stage breakdown of a device which is caused by an excessive electric field produced by a connection part above the insulating region 18 can be avoided. The width (1) of each ring 11 and the spacing (d) between the rings 11 have influence upon the linearity of the potential distribution between the polysilicon rings and, on the other hand, the length and surface density of the protective link around the insulating region 18 determines the maximum breakdown voltage of the device.

Filed: 1986-04-18
Abstract: PURPOSE:To synthesize video signals and character signals without giving disturbance to a chrominance signal, by mixing the luminance and chrominance signals after synthesizing the luminance and character signals and then eliminating the noises of a chrominance signal band. CONSTITUTION:A switch set within a character signal synthesizing circuit 3 is opened and closed in response to the character signal 8 received from a character signal generating circuit 2. The luminance signal is outputted from a character signal synthesizing circuit 3 while the swich is kept open. While the DC voltage is outputted when the swich is kept close. The component cover ing a chrominance signal band is deleted by a noise eliminating circuit 4 out of the higher harmonic component of the pulse wave produced by open/close of said switch. Thus the luminance and character signals are synthesized and the signal obtained by eliminating the chrominance signal band out of said synthetic signal is mixed with the chrominance signal by a color signal mixer 6. These mixed signals are extracted as a video output signal.

IPC: G01T1/17
Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To prevent the crest part of a step form wave from having an inclination to a base line and to prevent peak sifts from occurring even when there is an inclination in the crest of the step form wave by inputting a signal proportional to the inclination of the step form wave and a signal proportional to the crest of the step form wave to a differential amplifier and inputting the difference signal of both.

A difference signal of signal levels C and B and a difference signal of signal levels E and A occur in the outputs D and F of operational amplifiers 3 and 3'. Dependently on whether the input signal A has an inclination or not, an inclination signal proportional to zero or to the inclination occurs in the output signal F and a pulse of constant crest or a pulse proportional to the crest in the output signal D.
