Title: Digital telephone terminal interface circuit
Inventor: SANO YOSHIO
IPC: H04M1/00
Filed: 1983-09-30
Abstract: PURPOSE:To consitute identically a line terminating device with an interface circuit of a digial telephone set by switching and generating a clock signal of the interface circuit in synchronizing with a clock signal incoming externally. CONSTITUTION:When the interface circuit 5' is used as the line terminating device, a standard clock signal of 8kHz is fed from a standard clock source to a terminal 57, and a signal allowing a selecting circuit 504 to select the standard clock signal of 8kHz is inputted to a terminal 59. As a result, all the clock signals are synchronized with the clock signal of 8kHz. On the other hand, when the circuit 5' is used for a digital telephone terminal device, a signal allowing the selection circuit 504 to select a reception signal of 80k-bit/sec is inputted to the terminal 59, resulting that a clock forming signal circit 506 outputs the clock signals of 64kHz and 8kHz synchronized with the reception signal of 80k bit/sec to terminals 57', 58' so as to use it as a reference of the clock signal applied from the circuit 507.

Title: Optical sensor
Inventor: MAAKU PII BENDETSUTO
IPC: H01S3/08
Filed: 1996-05-28
Abstract: PROBLEM TO BE SOLVED: To provide an optical sensor, which outputs a sufficiently large output power so that measurement can be readily performed even with an integral type optical sensor, and can output further accurate result without the requirements for through calibration and the highly controlled environment. SOLUTION: A waveguide 18 comprising a base material 16, which is doped with a rare earth element, is included in a device 12 of an integral type optical sensor. The ray, which is propagating along the waveguide 18, excites the element, and the element emits light. Thus, the total amount of the light propagating in the wavelength 18 is increased. Since the waveguide 18 itself acts as the laser, the change in optical characteristics of a material under analysis forming a part of a laser cavity affects on the operation of the laser. Therefore, the wavelength or the power of the light generated from the laser is changed directly in correspondence with the change in concentration of the material to be sensed. The change is emphasized by the intrinsic gain characteristic of the laser medium.

Title: Current detecting circuit
Inventor: TAKAYAMA TOMIO
IPC: H02M3/155
Filed: 1981-11-19
Abstract: PURPOSE:To detect the current flowing through a transistor of a current-feedback transistor driver at a low cost and with a small power consumption, by a method wherein a resistor is series-connected to a circuit connected to the base terminal of the transistor, and a current is drawn out from both ends of the  resistor. CONSTITUTION:A resistor R2 is connected to the base circuit of a transistor Q2, and the current flowing through the transistor Q2 is detected from the base current of the transistor Q2 proportional to the emitter current of the transistor Q2. The base current of the transistor Q2 is determined according to the emitter current of the transistor Q2 and the turn ratio between windings T3a and T3b of a transformer T3. Since the turn ratio T3a/T3b is selected to be (hFE+1) times as much as the emitter current, the base current is 1/(hFE+1) of the emitter current.

Abstract: PURPOSE:To propagate light in one of two orthogonal polarization modes by equalizing the refractive index of strain inducing parts, which face each other in a 2nd clad across a core at right angles to the axis, to the refractive index of the 2nd clad. CONSTITUTION:The core 11 of the part of a radius (a) from the center has a refractive index n0 and the 1st clad 12 of the outside part of a radius (b) has a refractive index n1 smaller than n0. Further, the 2nd clad 13 and the strain inducing parts 14a and 14b provided in the 2nd clad have the refracting index n2, which is between n0 and n1.

Abstract: PURPOSE:To obtain mono- and dimethylamine on a large scale by making methanol react with ammonia in the presence of a catalyst consisting of the substance obtained by treating water-containing mordenite with a silylating agent in a liquid phase under suppressing the formation of trimethylamine. CONSTITUTION:Methyl amines, especially mono- and dimethylamine rather than trimethylamine, are obtained from methanol and ammonia on a large scale. This reaction is carried out with a catalyst obtained by treating mordenite containing 3-40wt.%, especially 5-30wt.%, of water with a silylating agent in a liquid phase. The silylating agent is selected from silicon alkoxide, e.g. tetramethoxysilane, silicon tetrachloride, dimethyldichlorosilane. The mordenite preferably has silica/alumina ratio of 10 or more than 10. This process dispenses with recycling of trimethylamine by disproportionation reaction and enables he simplification of the manufacturing process of methylamines and the reduction of energy consumption.
