Title: Discharge lamp lighting device
Inventor: OCHI MASAFUMI
IPC: H01J61/54
Filed: 1982-11-25
Abstract: PURPOSE:To prevent an erroneous operation or breakage of a device by detecting the current, voltage or power from a ballast resistor of a discharge lamp feeding circuit and controlling the width of an output rectangular wave of a high-frequency power converter in response to the DC voltage signal of a detection circuit. CONSTITUTION:A high-frequency power converter 2 is driven by a power supply 1 and electricity is fed to a discharge lamp 5 through an output transformer 3. The lamp current is detected from part 41 of a ballast resistor, and the voltage proportional to the lamp current is charged into a capacitor 62 as DC voltage through a rectifying diode 61. This voltage is applied to a pulse width modulation drive circuit 7, and an output with a pulse width corresponding to the voltage value of the capacitor 62 is obtained from the circuit 7. The converter 2 is driven by the circuit 7 and its output becomes a rectangular wave with the same duty cycle. The lighting waveform is thus controlled in response to the current value of the discharge lamp, thereby an excessive current at the time of starting can be prevented. In addition, the resistance value of the ballast resistor is made small and the ratio of the transformer-fed output voltage against the lamp voltage is made 0.7 or higher, thus the efficiency can be improved.

Filed: 1997-07-16
Abstract: PROBLEM TO BE SOLVED: To facilitate cleaning of an objective lens for reading by providing a member opposite to the lens with an opening part in a position opposite to the lens. SOLUTION: When a tray 10 as a part of a disk moving means is in a position before its movement, and a carriage 34 is in a home position, i.e., a position of repose before playing, the tray 10 is formed with the opening part 10d in a circular shape opposite to the objective lens 33a.

Title: Power ic
Inventor: MATSUSHIMA HISASHI
IPC: H03F3/30
Filed: 1992-07-31
Abstract: PURPOSE:To prevent an output transistor(TR) from being destroyed by supplying a current to a power supply line via a diode being an emitter-open transistor(TR) when a voltage at an output midpoint reaches an abnormally high voltage. CONSTITUTION:The integrated circuit is provided with an output TR Q1 at a power supply side for current delivery and a ground side TR Q2 for current absorption, and also a diode QX being an open emitter TR connecting an output midpoint O to which both TRs Q1, Q2 are connected and a power supply line, and the TR QX is formed in the same region as that of the TR Q1 while the collector is used in common. Since the TR QX is the open emitter TR and acts like a diode, when a level at an output terminal OUT is higher than a power supply line +B due to any cause, a prescribed current flows to the power supply line via the TR QX. As a result, the output TR Q1 is bypassed and then no reverse current flows to the output TR Q1, thereby protecting the output TR Q1.

IPC: G01S13/76
Filed: 1986-09-02
Abstract: PURPOSE:To reduce the misdecoding frequency of codes by using a code in a stable area after being set as a target for code verification. CONSTITUTION:An input answer code 1 is inputted to a gate 6. Here, it is gated with a signal of target establishment. When no target is set, the answer code is ineffective and when the target is set, the answer code is outputted as an effective code by the gate 6. The output answer code of the gate 6 is delayed by a delay circuit 2 while the time relation is maintained for the repetition time of one transmission time. A coincidence circuit 3 checks the coincidence between the answer code which is delayed by one transmission time and a code which is outputted by the gate 6 currently. When the last and current answer codes are both effective and the last answer code coincides with the current answer code, a code which meets the requirements first is employed as the answer code of an aircraft.
