Title: Through hole mask device for light leak inspecting method
Inventor: SUZUKI SHINJI
IPC: G01N21/956
Filed: 1989-07-28
Abstract: PURPOSE:To improve the inspection accuracy by bringing a ball-shaped mask into contact with a through hole and masking one opening part of the through hole. CONSTITUTION:A printed board 5 to be inspected is moved by motors 11 and 12 together with a stage 2 and when a target through hole 5a comes onto a CCD sensor 6, the sensor 6 detects transmitted light directly from the hole 5a and inputs a through hole image to a position image input circuit 14. This signal is delayed 13 by a time required for the through hole to be inspected to move to right above the CCD sensor 7. After the through hole passes over the sensor 6, gas supply parts 3 and 3' send gas to float the ball-shaped mask 1 and the bottom of the hole 5a is covered with a lid. Then when the hole 5a comes to right below a sensor 7, a gas suction part 4 sucks the mask 1 and the bottom of the hole 5a is covered hermetically. At this time, an image input part 15 inputs an image of light leaking into the through hole from the sensor 7 and ANDs it with the position information inputted from the sensor 6, so that the decision result of a defect decision circuit 16 is outputted from an output circuit 17.

Title: Dc/dc converter
Inventor: MITANI HIROAKI
IPC: H02M3/155
Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To provide a DC/DC converter which can simply control its output voltage, through the surrounding temperature. SOLUTION: A thermistor 11 with a negative resistance is substituted for a resistor 10, which is the ground side resistor of two resistors 9, 10 for sensing an output voltage V2 of a DC/DC converter, or the thermistor 11 is connected in parallel with the resistor 10. While the resistance of the thermistor 11 is decreased when its temperature rises by its increased ambient temperature, since a sensing voltage V3 of the output voltage V2 for the DC/DC converter is kept constant, the output voltage V2 increases as a result. For example, for driving a radiation fan used for the heat radiation of a PDP for displaying a picture, etc., the rotation speed of the radiation fan is increased in the case of the increased ambient temperature to improve the radiating operation of the radiation fan.  Conversely, the rotational speed of the radiation fan is decreased in the case of a decreased temperature to reduce the consumption power and noise of the radiation fan.

Title: Printer-controlling system
Inventor: SAKAGAMI WATARU
IPC: B41J29/38
Filed: 1983-10-20
Abstract: PURPOSE:To enable to greatly prolong the useful life of a power source such as a battery, by a method wherein the operation of a DC-DC converter for operating a head and various driving motors is stopped when the output therefrom is not used. CONSTITUTION:When the subsequent printing data C are not inputted into a CPU2 after throwing in a power source or after completion of a printing operation, a line-feeding operation or the like, an operation-stopping signal S1 is outputted to stop the operation of the DC-DC converter 1 until the subsequent printing data are inputted. When the subsequent printing data C are inputted, an operation-starting signal S1 is outputted to start the operation of the converter 1, thereby processing the printing data C. In this case, when the amount of the printing data C is small, the processing is completed before an output voltage of the converter 1 is reached, resulting in that drive-controlling signals are outputted to the head 4 and the motor 5. To avoid this problem, the printing operation is effected by a signal S2 outputted when it is detected by a detecting circuit 3 that a prescribed voltage is reached. Accordingly, the power source such as a battery can be prevented from being consumed due to a reactive current.
