Patent JP-S6472062-A (JP)
Title: Diffusive trapper
Inventor: BUORUFUGANGU MAI
IPC: G01N1/22
Filed: 1988-09-01
Abstract: PURPOSE: To improve the detecting sensitivity of a diffusion collector and miniaturize the structure of the collector by providing an elongated plate-like carrier in the internal space of a tubular container to which a gas to be inspected is led and constituting the carrier in a transforming section and the internal surface of the container in a collecting section. CONSTITUTION: A plate-like carrier 3 is extended from one end of the inlet hole 2 of a gas detector 1 to the other end. Both side faces of the carrier 3 are constituted in transforming sections 6 and the internal surface of the container 1 is constituted in a collecting section 5. At the time of detecting, for example, an NO gas, a chromium oxide (IV) is held in the transforming sections 6 and triethnolamine is held in the collecting section 5. Then a sample gas is made to flow through the container 1 and the NO is oxidized into NO2 with the chromium oxide (IV) and the NO2 is discolored with the triethanolamine. The progress of the discoloration can detected from the scale divisions 7 marked on the external surface of the container 1. Since the sample gas is discolored by providing the carrier in the container 1, the detecting sensitivity can be improved.

Title: Image-pick up device
Inventor: SUGA AKIRA
IPC: H04N5/378
Filed: 1988-08-31
Abstract: PURPOSE:To reduce circuit elements and to cause a whole circuit to be compact by using a line memory, which is originally included in an image-pick up device, as a delay element. CONSTITUTION:When a switch 62 is connected to the side of an external input terminal 42A by an nH-th signal, the nH-th signal of an input terminal 50 is stored to a capacitor 16M, which is used for the storage of an R signal at the time of image-picking up, in a line memory 16. At such a time, since a switch 64 is connected to the side of an output terminal 26B, a signal before 1H to be stored to the capacitor 16M, which is used for the storage of a G signal, is read at the time of the imagepicking up and impressed from the switch 64 to an LPF66. The switch 62 is connected to the side of an external input terminal 42B by an (n+1)H-th signal and since the switch 64 is connected to an output terminal 26A side, the (n+1)H-th signal of the input terminal 50 is stored to the capacitor 16M, which is used for the storage of the G signal, at the time of the image-picking up and the nH-th signal is read and impressed from the switch 64 to the LPF66.

Title: Controlling apparatus for thermal transfer system printing
Inventor: MORI TAKAHISA
IPC: B41J2/36
Filed: 1986-09-12
Abstract: PURPOSE:To obtain uniform printing quality from the start of printing scanning to the finish thereof regardless of printing pixel density, by measuring printing pixel density and changing the energy applied to a thermal head corresponding to the measured density. CONSTITUTION:When printing scanning operation is started, a printing control apparatus 1 controls the voltage applied to a thermal head 6 from a voltage supply source 7 corresponding to the printing pixel density data stored in a printing pixel density memory apparatus 5. That is, in sections S3, S5 where printing density is 50% or more, voltage V1 is applied to the thermal head 6 and, in sections S1, S2, S4 where printing density is below 50%, voltage V2 is applied to the thermal head 6. By this method, the thermal head accumulates heat in sections high in printing density and the generation of irregularity of printing density is prevented.

Title: Optical character reader
Inventor: SHIMANOE YASUHIRO
IPC: G06K9/20
Filed: 1985-09-30
Abstract: PURPOSE:To carry stably forms having folds or warps by providing at least two guide members between a driving member at the side of a separate member and a reading part among those plural drive members to hold and guide the forms with a slight gap. CONSTITUTION:Two guide plates 16 and 17 are fixed to a device frame above a drive roll 7 and an idler roll 9 through an end of each guide plate. The other end of the plate 16 is opposite to a guide plate 13 with a slight gap at a rear point P of the roll 7. While the other end of the plate 17 is opposite to the plate 13 with a slight gap at an intermediate point Q between a drive roll 8 for the plate 13 and a reading part 6. The plate 16 has no contact with a form 1 and produces no resistance before the form 1 reaches both rolls 7 and 9. The lower ends of both plates 16 and 17 hold the form 1 with slight gaps at points P and Q of the plate 13. Therefore, the folds or warps of the form 1 are corrected at both points Q and P. Thus the form 1 is moved straight with no skew.

Abstract: PURPOSE:To clean up any water drips sticked on a wafer surface instantaneously and throughly by a method wherein an element to be dried up is arranged in high temperature inert gas atmosphere irradiated with infrared rays so as to be dried up. CONSTITUTION:A gas feeder pipe 4 heated by emission heat from a medium wavelength infrared ray lamps 5 is led to the upper part in a drying chamber 1 and then bent downward in the drying chamber 1.

Title: Feed screw supporting device
Inventor: YOKOYAMA KATSUHIKO
IPC: B23Q5/40
Filed: 1988-08-31
Abstract: PURPOSE:To support an upward vibrating load by an intermediate support and to improve a following characteristic at the time of a high speed movement by providing a pulley device having a running block between the intermediate support supported by a linear guide device, a frame and a nut. CONSTITUTION:When a screw axis 1 is turned by a rotation drive device M, a nut 2 is moved to the left, a machine table 8 is guided by a linear guide device and smoothly moved. At this time, when a distance L between support points of the shaft 1 is long, the axis 1 is resonates. However, since intermediate supports 20A, 20B are provided, the distance between the support points is L/2 at a maximum, a dangerous speed is four times as high as u and the axis hardly resonates. Then, while the nut 2 is moved left-ward, the supports 20A, 20B are pulled through the rope 24 of a pulley device 22 and a running block 23B and moved in the ratio of 1/2 of the moving distance of the nut 2. Accordingly, when the nut 2 is moved by L/4 to reach to a point P1, a support span (a) is expressed by (a) = (3/8)L and shorter than the conventional L/2 and an axis danger speed is enhanced to a safe side.

IPC: H04L29/10
Filed: 1986-09-18
Abstract: PURPOSE:To prevent consecutive storage to a data storage memory of next text by inhibiting the transfer of the next text to the data storage memory until the end of reset processing of a DMA controller after the end of reception. CONSTITUTION:When a preceding text 1 is inputted to a DLC 4 while a flip-flop 10 is reset, a text A is transferred to a data storage memory 2 under the control of a DMA controller 3. When the DLC 4 detects the end of text 1, the DLC 4 generates a pulse on a reception end interruption signal line 7. When the reset processing of the DMA controller 3 by a CPU 1 is delayed, the flip-flop 10 is kept to be set, a DRQ signal is blocked by a gate 11 and not sent to the DMA controller 3. Thus, the storage of the preceding text and the next received text in consecutive addresses of the memory is prevented.

Filed: 1994-08-19
Abstract: PURPOSE: To elongate a life of a battery and improve a portability of an apparatus by setting an elastic member urging an upper ring gear and a lower ring gear in different directions, and engaging one end part of the elastic member to a chassis. CONSTITUTION: A lower ring gear 64 is arranged below an upper ring gear 71. When a loading motor is rotated, the upper and lower ring gears 71, 64 stop to rotate, and therefore an upper slide plate 83 is moved in an A direction along the lower ring gear 64. As a result, the upper and lower ring gears 71 and 64 are urged by a predetermined force in opposite directions. Since the upper slide plate driving/urging the lower ring gear slides with a slight force at this time, a life of a battery as a power source for the upper slide plate is elongated, and the apparatus is more improved in portability.
