Title: Optical sensor
Inventor: SAKAKIBARA MASAHIRO
IPC: G01K11/12
Filed: 1980-05-14
Abstract: PURPOSE:To easily detect temp. change without receiving the effect of disturbance noise by fetching the change rate of temp. directly as the change rate of light signal and transmitting the same to a signal processing part by means of an optical cable. CONSTITUTION:Rays lambda1, lambda2 of different light wavelengths are emitted from light sources 6, 8, are subjected to light wavelength multiplexing by a wave combining device 7 and are injected into an optical fiber cable 9. The output of the light source 8 is also supplied as reference light electric power to a photodetector 17. The light of lambda1, lambda2 transmitted through the cable 9 is separated by a wave separating device 10, of which lambda1 is given the displacement by temp. change through a light attenuating element 11, and lambda2 is subjected to light wavelength multiplexing with lambda1 by a wave combining device 14 without going through the element 11, and is injected into an optical fiber cable 16. The light transmitted by the cable 16 is subjected to light wavelength separation by a separating device 18; of which lambda1 is converted to the temp. change of an observing part 15 in its rate of light attenuation by a photodetector 19. lambda2 Is compared with the reference light electric power from the light source 8 by the photodetector 17 and the light electric power of lambda1 from the light source 6 is increased by th detection output thereof by as much as the loss component of the transmission line.

Title: Optical amplifier multistage repeating transmission line
IPC: H04B10/293
Filed: 1992-03-19
Abstract: PURPOSE:To reduce the quantity of spontaneous emission light(ASE) as a whole by adopting plural optical amplifiers including wide band optical filters and narrow band optical filters with an optical amplifier arranged on an optical transmission line. CONSTITUTION:The optical amplifier multistage repeating transmission line 10 consists of plural 1st optical amplifiers 11 each of which is provided with a wide band optical filter 16-1 including the center frequency of signal light and having a required band width, plural 2nd optical amplifiers 21 each of which is provided with a narrow band optical filter 16-2 having a band width narrower than that of the filter 16-1 and the optical transmission line 12 connecting respective optical amplifiers 11, 21.

Title: Coordinate detecting system
Inventor: KOMADA SATOSHI
IPC: G06F3/0488
Filed: 1987-03-18
Abstract: PURPOSE:To make capacity of a storage device extremely small so as to make a device an inexpensive one by dividing a range 0-90 deg., which a phase can have, into n-number of sections, reading out the parameter corresponding to the section and obtaining the position of a coordinate. CONSTITUTION:At first, to what section the phase theta detected by an input pen 5 belongs is decided. namely, (i) which satisfies the section Pi-1<=theta<Pi is obtained. Next, the parameters Ai and Bi corresponding to the said section is fetched from a storage device 6 according to (i). By executing a computation such as AiXtheta+Bi to the fetched Ai and Bi, the position X corresponding to the phase theta can be obtained. Since the position X is obtained only by providing a transformation table written in the parameters Ai and Bi corresponding to the section (i) and a section end point Pi, whose number is as same as the number (n) of the section (i), even if the resolution of the phase theta and the position X rise, in the storage device 6, the capacity of storage is made small and the device is made inexpensive.

IPC: G11B7/00
Filed: 1986-03-20
Abstract: PURPOSE:To substantially increase data recording capacity by executing additional recording subsequent to an already recorded part. CONSTITUTION:At the time of recording of a disk, an identifying signal SD is inserted in advance into a part before a set period from a terminal of a recording signal.

Title: Additional unit for traffic intensity measurement
Inventor: HOSONO HIROMI
IPC: H04Q1/20
Filed: 1979-05-23
Abstract: PURPOSE:To make it possible to measure traffic intensity several times by a simple instrument by providing a circuit unit and controller and by connecting them to SS and SR terminals of a trunk by connection cords. CONSTITUTION:Both SS and SR terminals of a trunk are connected to traffic- intensity-measuring additional unit 1 by clips of connection cords. Then when a call is made by a private exchange subscriber, circuit unit 2 detects the SS terminal being grounded to become ready for operation. At this time, a positive-directional loop current is supplied from unit 2 to a traffic-intensity measuring instrument via control unit 3. Next, when a dial impulse arrives at the SS terminal through the dialing of the subscriber, this is detected by unit 2 and transferred to unit 3, which intermits the loop current of the subscriber's-traffic-intensity measuring circuit of the traffic-intensity measuring instrument. When the dialing of the calling subscriber ends and a called subscriber is selected and makes an answer, the SR terminal is  grounded. At this time, unit 2 detects the SR terminal being ground to supply unit 3 with a signal, thereby inverting a supply current to the traffic-intensity measuring instrument

Filed: 1988-03-18
Abstract: PURPOSE:To improve drain withstand voltage and simultaneously increase an ON current by providing an impurity diffusion layer and a leading-out electrode being conductive to the impurity diffusion layer directly under the insulating films provided at least under a part of a drain region and an offset region respectively and inside a silicon substrate. CONSTITUTION:An N-type diffusion layer 10 is provided directly under an underlying insulating film 2 near a drain region 6, a leading-out electrode 11 is connected to the N-type diffusion layer 10 through a contact window provided on the underlying insulating layer while being constituted so as to be able to impress positive potential from outside. In this way, by newly providing the N-type diffusion layer 10 on an offset gate type MOSFET of a prior art type SOI construction, the potential difference between the drain region and a silicon substrate can be held small. Accordingly, since the potential difference between the drain region and the silicon substrate can be weakened by imparting the positive potential to the N-type diffusion layer, drain withstand voltage can be raised. Further, the potential in the offset region can be raised so as to increase an ON current of the transistor.
