Title: Oscilloscope
Inventor: NARUKAWA YASUNORI
IPC: G01R13/30
Filed: 1984-03-09
Abstract: PURPOSE:To measure a voltage from the grounding level to an optional point of a waveform by indicating the grounding level together with the waveform in an oscilloscope to facilitate the confirmation of the grounding level, further indicating a DELTAV cursor. CONSTITUTION:An input terminal 1 of a signal is connected to an amplifier through a switching circuit 2, and a signal switching device 4 switches the output of an amplifier 3 and a memory circuit 6 alternately and drives a CRT. A controlling circuit 7 switches the circuit 2 intermittently by a controlling signal (c). Grounding level is stored in a sample hold circuit 8 through the amplifier 3, and A/D converted 9. Converted digital value is D/A converted 11 through an adder circuit 10 and applied to the switching device 4. At this time, the output (h) of a DELTAV setting circuit 12 is supplied to the circuit 10 intermittently for a fixed time, and the waveform different in level corresponding to potential difference from the grounding level to DELTAV cursor is obtained. Further, the voltage from the grounding level to an optional point of a waveform can be obtained by changing the value fed to the circuit 12.

Title: Data communication equipment
Inventor: YOSHIDA TAKEHIRO
IPC: H04N1/32
Filed: 1995-03-03
Abstract: PURPOSE: To execute suitable communication in accordance with an opposite party without complicating a communication procedure by providing this data communication equipment with a means for selecting the start of a procedure based upon full duplex communication or the start of a procedure based upon half duplex communication in accordance with the detection of a judging means. CONSTITUTION: A procedure is transmitted/received by full duplex communication at first. In the initial procedure (line proving exchange to CFR communication) of V.8 and V.34 procedures, each of a calling side and a called side ends communication when a response signal to a sent procedure signal is not received even after the lapse of prescribed time from the start of sending the procedure signal to the opposite party and then starts redialing. At the time of redialing, the communication is retried by a half duplex communication procedure based upon T.30 recommendation. In this case, the semi duplex communication procedure is executed from the sending of NSF, CSI and DIS by the called side.
Patent JP-S63209309-A (JP)
Title: Microwave semiconductor device
Inventor: IIDA AKIO
IPC: H01P1/162
Filed: 1987-02-26
Abstract: PURPOSE:To improve the detection sensitivity by adopting the constitution that ground conductors of a coplaner line are connected via a termination resistor so as to reduce the reflection of a sampling pulse passing through a diode and propagating through the coplaner line. CONSTITUTION:The ground conductors 20a, 20b of the coplaner line 3 are connected via a termination resistor 19. A sampling pulse propagated on the line 3 in the even number mode causes a potential difference between the ground conductors 20a, 20b, the potential difference is absorbed by the termination resistor 19 and diodes 8a, 8b are not switched in an undesired time. On the other hand, since the signal wave propagates on the line 3 in the odd number mode and no potential difference is caused between the ground conductors 20a, 20b of the line, no current flows to the resistor 19. Thus, the signal wave is applied to the diodes 8a, 8b without being attenuated by the termination resistor 19.

Title: Sheetlike carbide and production thereof
Inventor: FUKUI IKUO
IPC: H01M4/587
Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To industrially produce useful sheetlike carbide from a carbonizing raw material in a continuous form by carbonizing a film prepared from an aqueous solution of a cellulosic ether such as an alkyl cellulose by casting. SOLUTION: This sheetlike carbide is obtained by controlling the solution film thickness of an aqueous solution of one or more cellulosic ethers such as alkyl celluloses, hydroxyalkyl celluloses and hydroxyalkyl alkyl celluloses used as a raw material so as to provide a desired film thickness after drying from the solution concentration thereof, casting the aqueous solution onto a substrate such as a glass plate, drying the cast solution at a temperature as low as possible by air-drying, etc., so as not to cause foaming, etc., then peeling the formed film of the cellulosic ethers from the substrate, baking the formed film at 450-600 deg.C in an inert gas atmosphere and carbonizing the film without completely burning the film.  Thereby, the process can remarkably be shortened when forming a powdery and a granular carbides into the sheetlike form with a binder and adverse effects of the binder on characteristics of a formed product can completely be removed.

Title: Control circuit of heat value of heating
Inventor: HANAUE TERUYASU
IPC: B65C9/00
Filed: 1984-03-08
Abstract: PURPOSE:To set always an optimum heating time independently of ambient temperature condition by counting the variance of the temperature, which is varied by centering a set temperature to set a transfer time. CONSTITUTION:Heat from a heater 22 is transmitted to a heat plate and is detected by a temperature sensor 42, and this detection signal is supplied to a comparator 43 and is compared with a set reference voltage 44. The comparison output is in the low level if the detected temperature is lower, but it is in the high level if the detected temperature is higher. A heater control circuit 45 generates a control signal, which flows or cuts off a current in accordance with the level of the comparison output, to control the calorific value of the heater 22. Meanwhile, an initial value is preset to a counter 46 from a lip switch 47, and the initial value is counted down by the pulse output from the comparator 43. By this counting operation, the time when the calorific value effective for transfer due to the temperature higher than a threshold is supplied to a material to be pressed is detected. Consequently, a desired transfer time is set.

Title: Reinforced structure of optical fiber type coupler
Inventor: SASAOKA HIDEYORI
IPC: G02B6/24
Filed: 1991-03-11
Abstract: PURPOSE:To obtain the reinforced structure which varies in neither polarization characteristics nor transmission characteristics with temperature by fixing an optical fiber and a coupling part where a jacket constituting the coupler is removed to a case for protection with an adhesive across a constant flank. CONSTITUTION:The coupler formed by removing the jacket of the intermediate part of plural optical fibers 1 and 1' and fusing and drawing them is stored in a case 2 for reinforcement and fixed to the case 4 with the adhesive intermittently in the length direction to form the reinforced structure. In this case, the part (b) where the jacket is removed is fixed while the adhesive 4 is not stuck in the circumferential direction of a fixed part. Thus, only one flank of the part (b) where the jacket is removed is brought into contact with the adhesive 4 and even when the adhesive 4 or case 2 expands or contracts, stress applied to the coupling part is reduced to make the influence upon the polarization characteristics extremely small. The consumption of the adhesive 4 in this method is reduced so the effect is further increased.

Filed: 1993-03-05
Abstract: PURPOSE:To maintain satisfactory appearances for an air-well void even though slippage occurs in arrangement of an upper and a lower unit in the air-well void, and to minimize works executed in site for making up corners in the air-well void. CONSTITUTION:A girth 52 is provided, through backing materials 54 and 56 made up in layered structure and split into two parts of upper and lower, to a joint between the lower end 38A of an end rail 38 for the upstairs-side unit and the upper end 44A of the end rail 44 for the downstairs-side unit. The backing materials 54 and 56 are so made that layers thereof can be separated individually as occasion demands. Therefore, in the case where there is any slippage in the arrangement of the upper and the lower unit, backing pieces 54A of the upper backing materials 54 (or backing pieces 56A of the lower backing materials 56) are removed in the amount equivalent to the amount of the slippage and after that, the remaining backing materials can be joined to the end rails 38 and 44. Thereby, the slippage occurring to the joint does not become visible to the inside of an air-well void 10, and works to be executed in site can be minimized because works for removing and joining the backing materials 54 and 56 only have to be done in site.
