Title: Optical sensor
Inventor: OOBA SHIGERU
IPC: G02B27/00
Filed: 1980-10-30
Abstract: PURPOSE:To realize the multiplicity of signal, by giving displacement to the gap between two sheets of reflection preventing films from the set state by the change of pressure of the enclosed liquid caused by the motion of a lever and thus varying the wavelength of the light that passes through the reflection preventing films. CONSTITUTION:The one/off signal of light or the continuous replacement signal of light is extracted to the rotation of a lever 1 from position alpha to beta or to the angular displacement. When the level 1 has displacement from position alpha to beta, a rotary shaft 2 rotates and then nut 5 moves by the screw thread. As the nut part 5 and a sealed container 6 are fixed to an attachment plate 4, the tip of the shaft 2 pushes the rear wall face 61 of the container 6 when the shaft 2 is rotated. As a result, the pressure of a transparent liquid 62 increases and accordingly the liquid 62 pushes the wall face of a reflection preventing film 64 as shown by an arrow C. Thus the space (d) between two sheets of film 64 varies to change the wavelength of the passing light.

Abstract: PURPOSE:To uniformly etch a corrosive metal to a specified depth when the metal corrosive to an etchant is etched and patterned with the etchant by cladding the metal with a metal noncorrosive to the etchant. CONSTITUTION:The surface of a sheet of Cu, etc., is etched by an etchant such as FeCl2 and patterned to decorate the surface. In this case, a sheet B of stainless steel, Ti, etc., having excellent corrosion resistance to etchant is placed on the Cu sheet A, and both sheets A and B are joined by cold rolling, hot rolling, etc., to form a clad material CM.

Title: Tracking error signal generating circuit of magnetic recording and reproducing equipment
Inventor: GOSHIMA KENJI
IPC: G11B5/588
Filed: 1984-07-23
Abstract: PURPOSE:To sample and hold the quantity of crosstalk accurately by resetting a pilot signal waveform temporarily before sampling the quantity of crosstalk from a right and a left adjacent track. CONSTITUTION:An envelope detecting circuit 6 stops tracking an envelope while a reset pulse 24 is generated and restarts tracking the envelope when the resetting is released. The time Trise from the releasing of the resetting to the generation of sampling pulses 18 and 19, i.e. the timing of resetting release is set in consideration of the time for the sufficient rising of an envelope detection signal. Consequently, even when the ripple signal component of the envelope detection signal is reduced and the quantity of delay is increased, the playback signal of one track is separated completely from crosstalk signal components from adjacent tracks and the quantity of crosstalk from the adjacent tracks is sampled and held accurately.

Title: Modem device and, device and method for controlling communication
Inventor: ATSUTA AKIRA
IPC: H04L29/10
Filed: 1999-06-02
Abstract: PROBLEM TO BE SOLVED: To correspond to a communication procedure by arbitrary recommendation by outputting an identification signal showing a recommendation type to a host on the basis of detected results of a plurality of frequency components parallelly detected from a procedure signal received from a call receiving side, while conforming to prescribed recommendation and switching and controlling an operation mode according to an instruction of the host. SOLUTION: A recommendation type with which a call receiving terminal performs communication can be identified by detecting a carrier frequency component of a procedure signal corresponding to an optional recommendation type. For this reason, when a communication terminal device 100 can correspond to the recommendation type with which the call receiving terminal performs communication, communication can be continued with the communication procedure of the recommendation type. Specifically, communication can be continued with the call receiving terminal according to a communication procedure, etc., on the basis of Recommendation V.34. Thus, in the case the procedure signal transmitted by the device 100 is different from the procedure signal transmitted by the call receiving terminal, loop state of an operation of the device 100 is prevented.
