Inventor: MERA MITSURU
IPC: H04N7/173
Filed: 1990-07-13
Abstract: PURPOSE:To prevent deterioration in a picture by providing a video memory connecting to a data bus and a display section and an analog switch section connecting to a camera section, a moving picture CODEC and the video memory selecting an output moving picture signal from the camera section and the moving picture CODEC and outputting the signal to the video memory. CONSTITUTION:In the case of storing a moving picture signal, a moving picture signal 25 outputted from a camera section 10 is fed to an analog switch section 21. The analog switch section 21 gives the signal to an input signal 26 to a moving picture CODEC 12. In the case of storing a still picture signal, the analog switch section 21 bypasses the moving picture CODEC 12 and sends the signal to a video memory 20 as an input moving picture signal 28. The video memory 20 sends the input moving picture signal 28 to a display section 11, in which the signal is displayed. The picture is frozen by stopping the reception of the input moving picture signal and a still picture is formed and it is transferred to the memory via a bus 14 and it is able to be sent to an opposite terminal equipment. The still picture is outputted easily by writing the signal from the video memory conversely.

Title: Evaporator for methanol reformer
Inventor: ISHIBASHI TAKAHIRO
IPC: B01D1/30
Filed: 1985-08-22
Abstract: PURPOSE:To permit the smooth evaporation of a methanol even if the supplying rate of the methanol increases by stepwise expanding the diameter of a coiled pipe from the upper part near a burner toward the lower part and making the diameters of an introducing pipe for an aq. methanol soln. and a lead-out pipe for an evaporating gas to coincide respectively with the above-mentioned diameters. CONSTITUTION:The aq. methanol soln. supplied to an evaporator 5 from a mixing tank passes through an introducing pipe 7 and evaporates gradually while flowing down in the coil pipe 6. The evaporation rate is high and the gas-liquid volume increases in the upper coil 61 near the burner but such increase is absorbed by the intermediate coil 6, then the lower coil 63 which are stepwise increased in the diameter and the considerable increase in the flow rate is obviated; therefore the quantity of the heat received in the lower coil 63 apart from the burner does not decrease. The restoration of the liquid phase from the gaseous phase is thus prevented. The smooth evaporation of the aq. metha nol soln. is made possible by increasing the supplying rate of said soln. even with the small-sized device.

Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To always accurately performs fetching and processing of an image and to prevent an original from meandering and being damaged by controlling drive voltage to a motor with polarity or size with which a running speed is suppressed to be below set value. SOLUTION: When an image is read, an armature current monitoring circuit 21 detects armature current of a motor 12 and outputs control voltage that makes the motor 12 an off state when it decides that a running speed exceeds a 1st maximum speed limit VA. Because of this, a braking force works so as to resist a force to be run by a user. Further, when the user runs it by applying a force, he detects the rotational speed of the motor 12 and decides whether or not the rotational speed exceeds a 2nd maximum speed limit VB. And, when the rotational speed exceeds the limit VB, control voltage that makes the motor 12 reverse rotation is outputted to a motor driving circuit 18, the motor 12 is made to be reversely rotated and the speed is forced to decelerate to be less than the limit VB.

A detecting part 12 detects the micro-voltage between the wire and the base metal and applies the same via an amplifier part 14 to a comparing amplifier part 15. A generator 16 sets the voltage VS corresponding to the wire voltage when the wire is over-plunged or over-floated as reference voltage. An amplifier part 15 detects and amplifies the difference between the VS and the detected voltage VW and applies the same via an amplifier part 17 to the motor 6. The motor 6 is driven by said voltage and is run to the direction where the VW coincides with the VS.
