Patent JP-H08307173-A (JP)
Title: Compander circuit and radio telephone system
Inventor: SEGAWA YUJI
IPC: H03G3/20
Filed: 1995-04-28
Abstract: PURPOSE: To suppress production of noise by providing an input signal amplitude detection circuit and a control circuit to adjust the attenuation of an attenuation circuit depending on a fluctuation of an amplitude of an output signal of the detection circuit so as to adjust a period of stopping revision of the attenuation of the attenuation circuit longer or shorter thereby smoothing adjustment of an electronic volume with respect to the fluctuation state of a level of an input signal. CONSTITUTION: When an amplitude detection circuit 11 detects a fluctuation in an amplitude of an input signal, a control circuit 12 receiving an output signal of the amplitude detection circuit 11 sets longer a period to stop revision of an attenuation of an electronic volume 13 when the fluctuation in the amplitude of the input signal is below a prescribed value and sets shorter a period to stop revision of an attenuation of the electronic volume 13 when the fluctuation in the amplitude of the input signal exceeds the reference value. Since the fluctuation in the amplitude of the input signal is detected and the period to revise the attenuation of the electronic volume 13 is adjusted by the control circuit 12, a rapid change in the attenuation is not caused and a steep amplitude change of the output signal is prevented.

Title: Waveguide type liquid detector
Inventor: MORISAWA MASAAKI
IPC: G01N21/41
Filed: 1988-04-28
Abstract: PURPOSE:To facilitate the generation and to improve the profitability by connecting a flexible waveguide film which has been bent to a U-shape to input/output optical fibers and using it. CONSTITUTION:A waveguide type liquid detector is formed by connecting input/ output optical fibers 3, 4, respectively to each end of a waveguide 2 obtained by bending to a U-shape a flexible organic substance film which has formed a waveguide by irradiating with a light beam and polymerizing a monomer of an exposing part in a state that masking has been performed to a sheet of a mixture of, for instance, a base organic high polymer and the monomer for varying its refractive index. In this state, by a liquid 5 which has adhered to the top part of the U-shaped bend part of this detector, an incident light is radiated into the air, a total reflectivity of the waveguide 2 is varied substantially and the liquid 5 is detected. By this cutting working, etc., the waveguide type liquid detector which can be generated easily and whose profitability is high is obtained by the constitution by which it is unnecessary to generate a flat part in the waveguide.

Title: Setting system for lower-rank device
Inventor: TSUNOSE KATSUJI
IPC: G06F11/22
Filed: 1979-08-22
Abstract: PURPOSE: To reduce the working inactive time of the system, by carrying out the diagnosis for the lower-rank device to which the setting is designated and then performing the setting only when the setting is possible.  
     CONSTITUTION: The MTU diagnosis part 28 transmits the signal to the gate control part 26 in order to give a diagnosis to the corresponding MTU20 when either one of the switches 25 is turned on. Thus the corresponding gate 23 is turned on. Then the part 28 transmits and receives the data to and from the relevent MTU20 via the gate 23, and then performs a diagnosis. As the result of the diagnosis, the part 28 detects that the relevant MTU20 can be made active and then transmits the signal to both the part 26 and the display control part 29. Thus the relevant gate 23 is kept on thereafter, and at the same time the corresponding display element 27 is lit up. After this, the data transmission/reception becomes possible between the MTC10 and the corresponding MTU20, and the MTC10 becomes active. And at the same time, the corresponding display element 27 is lit up. Thus the fact that the corresponding MTU20 has been selected is displayed.

Title: Input voltage drop detecting circuit
Inventor: TAKAMURA AKISUKE
IPC: G05F1/10
Filed: 1991-04-11
Abstract: PURPOSE:To prolong output voltage ensuring time at input voltage drop under light load and to lower power dissipation in an input voltage drop detecting circuit for a switching power supply. CONSTITUTION:Switching pulses (a) for a performing ON/OFF control of a switching element are integrated through an integrating circuit 6. An integrated output (c) and a reference voltage (b) are then subjected to level comparison through a comparator 7. Input voltage drop is detected based on the comparison result (d). Since the saw-tooth signal (c) obtained through integration of the switching pulse (a) is subjected to level comparison with the reference voltage (b), time for reaching the reference level is prolonged when the load is light even if the input voltage drops and thereby the output voltage ensuring time is prolonged. Both the integrating circuit and the comparing circuit are constituted to dissipate low power.

Title: Dielectric filter and method for coupling and adjusting the same
Inventor: SANO KAZUHISA
IPC: H01P1/205
Filed: 1988-04-28
Abstract: PURPOSE:To set the coupling state between resonator units optionally by providing a conductor rod inserted to a coupling hole penetrating a dielectric block formed between the resonator units. CONSTITUTION:A coupling pin 19 with similar structure to that of an input/ output coupling pin 13 is inserted to a coupling hole 18 between resonator units. Thus, with the conductor pin 19 inserted to the coupling hole 18, since magnetic flux produced by an input current keeps clear of the said conductor, the magnetic flux passes the outside of a dielectric band block 10, the magnetic flux interlinked with the output pin is increased, the coupling coefficient is increased and the band width is spread. Since the distribution of the magnetic flux differs between the short-circuit end and the open end, the coupling state is adjusted by any of the diameter, the length and the position of the conductor rod 19. Thus, the coupling state between the resonator units is adjusted optionally.

Mainly the center of the edge part (the opposed welding surfaces forming a wedge shape) is preheated by the beam 10 in this case. The beam 10 is passed through a scanner 8 oscillated at a specified period around the weld point so as to copy the material to be welded. The central part of the wall thickness where the heat input is low with the mere heating by the high frequency current on the welding surfaces facing each other is irradiated and heated by a guide 9 which irradiates always the beam 10 from the open side of the wedge shape to the peak direction to be the weld point. The uniformity of the temp. at the weld point is thus improved.
