Title: Flow cell for fluid sample
Inventor: YAMAO YASUO
IPC: G01N21/05
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of air bubbles in a cell chamber by setting a ratio between the inner diameter of a cell inlet pipe and the inner diameter of a cell outlet pipe at a specific ratio. SOLUTION: The inner diameter L of a cell inlet pipe 43 is set larger in size than the inner diameter S of a cell outlet pipe 45. In the figure example, the inner diameter L of the cell inlet pipe 43 is ϕ1.8 mm, and the upper and lower limits of tolerance is set within a range of 0.1 mm. In addition, the cell outlet pipe 45 is ϕ-1.5 mm, and the upper and lower limits of tolerance is set within a range of 0.1 mm. Therefore, in a ratio between the inner diameter L of the cell inlet pipe 43 and the inner diameter S of the cell outlet pipe 45, letting the inner diameter L of the cell inlet pipe 43 be 1, the limit of tolerance of the inner diameter S of the cell outlet pipe 45 lies within a range from 0.73 to 0.94. By setting such a ratio of inner diameter, it is possible to suppress the occurrence of air bubbles as much as possible or to prevent the occurrence of them.

Title: Optical character reader
Inventor: SHINDO TSUNEFUMI
IPC: G06K9/03
Filed: 1988-05-31
Abstract: PURPOSE:To improve operability and to accurately correct an unreadable character by displaying a video pattern on the display position of a character decided as an unreadable character by a deciding device during the reading of characters. CONSTITUTION:A character on a document 11 is detected as a scanning signal by reflected light from a lamp 7 and the scanning signal is converted into a video signal by a scanner controller 1. The video signal is decided as a character by the deciding device 3 and the read result is stored in a memory 4 together with the video signal. When an unreadable character exists at the time of displaying characters on a display 5, a video pattern based upon the video signal is displayed on the position of the unreadable character. In this case, a processor 2 controls the transmission/reception of signals among the controller 1, the device 3, the memory 4, and the display 5 and also controls the display 5 so as to display the video pattern and distinguish the read character. The character is corrected on the video pattern display position by operator's input operation. Thus, the operability can be improved and the unreadable character can be accurately corrected.

Title: Air blowing type heater
Inventor: MURASE KOJI
IPC: F23N5/14
Filed: 1995-05-30
Abstract: PURPOSE: To improve the comfortableness of heating by controlling a temperature adjustment under use of a heat regenerator as a heat source during the off-control of combustion and preventing an actual room temperature from being extremely lowered upon start of afterburning. CONSTITUTION: During off-operation of combustion, a circulator 24 is operated and a heat accumulator 28 which accumulates and stores a part of the radiation heat of a heat exchanger 27 during a combustion operation continues to radiate the small quantity of heat as a heat source, in place of the heat exchanger 27. Thus, the excessive rise of a room temperature is suppressed and a comfortable heating performance having no feeling of cold air can be obtained and fuel consumption can be reduced. Further, even after the heat exchanger 27 is stopped, the operation of the circulator 24 is continued and hot air is prevented from being stored in a device, so that the influence of temperature upon a thermistor 21 is decreased.  Accordingly, the on/off control of combustion can be carried out based on correct temperature information with no error and a coldness due to the fall of the room temperature upon off-control of combustion can be improved.

Title: Multi-picture television receiver
Inventor: FUJISHIMA YUKITOMI
IPC: H04N5/45
Filed: 1995-05-30
Abstract: PURPOSE: To prevent picture omission from being generated by making the display positions of two compressed images mutually eccentric to a center and synthesizing those images while making overscan width equal with the time of one picture. CONSTITUTION: When a source image has the width of a video term of W2 corresponding to the display width of W1, a source image 1 is compressed to be [(1/2)+α)]-fold, another source image 2 is displayed on the left side, and the image compressed to be [(1/2)+α]-fold is similarly displayed on the right side. At such a time, when the overscan width is set equal with the time of one picture, two compressed images are displayed on the right side and left side while respectively getting over from the center of a display screen for W2, and the compressed images of [(1/2)+α]W2 are synthetically displayed while being overlapped just for 2αW2 at the center.  Therefore, by suitably setting the value of α, at the time of displaying two pictures, a compression ratio is increased just for +α to the compression ratio while securing the required overscan width concerning two main and subordinate display pictures.

Filed: 1992-04-24
Abstract: PURPOSE:To damp the vibration when a color display body rotates and stops and to enable the rapid switching of display colors by constituting the driving waveforms to be applied to coils of acceleration pulses, deceleration pulses and braking pulses. CONSTITUTION:The deceleration pulses to apply the rotating force of a reverse direction to a magnet 116 are provided between the acceleration pulses and deceleration pulses to be applied to the coils 117 to 120. The N pole of the magnet 116 beginning to rotate counterclockwise from the flat state of a speed curve is increased in rotating energy by the inertial of the magnet 116 and the color display body 12. Then, the rotating force tending to pull back the magnet 116 to its home position is applied to the magnet 116 by the deceleration pulses. The brake is rapidly applied to the magnet 116 by this reverse rotating force and the magnet is sufficiently decelerated. The braking pulses act to stop the magnet 116 when the magnet 116 comes to the stop position by passing this section. The vibration of the N pole of the magnet 116 is suppressed during this time.
