Title: Stock price data display device
Inventor: OKUWAKI KATSUHISA
IPC: G06Q40/04
Filed: 1998-02-12
Abstract: PROBLEM TO BE SOLVED: To reduce cost and power consumption and to improve facility of seeing the display of rise and fall by displaying the color of a data display screen in red when stock price fluctuation rises higher than the set value and in green when it falls in correspondence with the rise and fall of stock prices. SOLUTION: A rise and fall lamp of a stock display part 71 is disused, and each data display screen 73 of a data display part 72 is composed of a display element changeable into red and green. In the data display part 72, the color of the data display screen 73 with data display characters 64 arranged to display data stock by stock is displayed in red when stock price fluctuation rises higher than the set value and in green when it falls in correspondence with the rise and fall of stock prices. The color change of the display screen 73 is controlled by a signal of a conventional rise and fall lamp. It can also be so constituted that a data frame is provided around the data display screen 73 and that the color of the data frame part is changed into red or green in correspondence with rise and fall.  The cost of a device and power consumption can therefore be reduced in comparison to a conventional device, and facility of seeing the display of rise and fall can be improved.

Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To realize a highly reliable laser operation by controlling temperature changing means so that an electric signal processing circuit can keep the temperature of a light amplifier constant. SOLUTION: A temperature detector 108 for detecting the temperature of a light amplifier 103, temperature changing means 109 for changing the temperature of the light amplifier 104 and an electric signal processing circuit 109 for changing the temperature changing means 109 based on the detection result of the temperature detector 108 are provided. The temperature of a rare earth metal added fiber is detected by the temperature detector 108 and inputted into the electric signal processing circuit 110. The electric signal processing circuit 110 outputs a temperature changing means driving signal and controls the temperature changing means 109 such that the detected temperature, if higher (lower) than a reference temperature, is reduced (increased). The procedure is repeated to thereby maintain the temperature of the rare earth added fiber to the reference temperature.  A change in the length of a laser resonator is prevented by controlling the temperature of the light amplifier which is the principal factor of the laser resonator length change. Thus, the realization of the stabilization of a laser operation is intended.

Title: Sheet handling device
Inventor: IKEDA YUTAKA
IPC: B65H7/12
Filed: 1998-02-26
Abstract: PROBLEM TO BE SOLVED: To separate and carry each of sheets by furnishing a sheet shifting means to shift the sheets making contact with a first carrier belt and the sheets making contact with a second carrier belt out of the accumulated sheets. SOLUTION: Pressing force to a pulley 4 increases when a carrier surface side belt of a carrier belt 3 comes to be in a tensile state. Additionally, pressing force to the pulley 4 decreases when the carrier surface side belt of the carrier belt 3 comes to be in slack state. When a travelling speed difference is made on the carrier belt as the belt comes to be in the slack state, as a friction coefficient between sheets and the belt is larger than a friction coefficient between the sheets, a difference is made in a travelling distance by the sheets 90 and the sheets 91.  Consequently, it is possible to shift the sheets 90 and the sheets 91 forward and backward in the carrying direction while carrying the sheets in the A direction by increasing carrying moving quantity in the A direction larger than carrying moving quantity in the B direction while continuously changing a rotational direction of the belt to the A direction and to the B direction.

Filed: 1992-03-03
Abstract: PURPOSE:To release a label from a mount by sharply changing the direction of a feed path only for the mount of label paper. CONSTITUTION:A printer device comprises a shaft 3 for leading label paper 5a upward from a platen 2 after the label paper 5a passes through the platen 2; a shaft 4 for leading the label paper downward through the shaft 3a; and a pair of feed rollers 6 for feeding the label paper 5a through the shaft 4. A printing head 1 conducts printing in a direction A. The platen 2 feeds the label paper 5a. The feed rollers 6 feed a mount 9. When a label 8 is fed to the shaft 3, a feed path for the mount 9 is sharply changed in direction. An adhesion and a frictional force between the label 8 and the mount 9 in the label paper 5a cannot resist this change. Thus, the label 8 is released from the mount 9 at the shaft 3.

Filed: 1996-02-07
Abstract: PROBLEM TO BE SOLVED: To correctly detect an automatic extinguishment temperature and disconnection of a thermistor by correctly detecting temperatures in a wide range with the use of the thermistor. SOLUTION: A plurality of resistors R1 , R2 , R3 are set to be connected in series with a thermistor TH. The resistors are changed over in accordance with a temperature of the thermistor.

IPC: F16D25/12
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To provide a clutch to prevent the entrance of a foreign matter to a sensor from a coupling part between a sensor to detect the engaging state of a clutch and a member to be detected to the sensor and prevent the occurrence of detective detection of a sensor or a trouble. SOLUTION: A clutch 10 is formed such that the clutch 10 is automatically disengaged and engaged through rotation of a release fork 30 based on a control signal for an engine control device without operation of a clutch pedal. The axis of a rod 34 coincides with the rotary shaft 200 of the release fork 30 and is rotated around the center of the rotary shaft 200 together with the release fork 30. Since the rod 34 is rotated without the occurrence of displacement in a position, a coupling part between the rod 34 and a rotation angel sender 100 is easily and reliably sealed by a dust seal 35. This constitution prevents entrance of a foreign matter to the rotation angle sensor 100 and prevents the occurrence of defective detection and a trouble in the rotation angle sensor 100.
