Title: Discharge lamp lighting device
Inventor: OGASAWARA HIROSHI
IPC: H05B41/24
Filed: 1998-08-12
Abstract: PROBLEM TO BE SOLVED: To provide a discharge lamp lighting device which has good efficiency of the lamp load even when the lamp is on in the low light flux dimmer condition and can preclude darkening of the end of the lamp or its being put off in the dimmer condition. SOLUTION: This discharge lamp lighting device is structured so that a high frequency power supply 1 is connected with the primary side of a piezo transformer 6 while one end of a discharge lamp load 2 is connected with the secondary side of the piezo transformer 6. When the lamp load 2 is full lighted, the drive frequency of the power supply 1 is controlled to allow the transformer 6 to make resonance near the first resonance frequency f1 and vibrate in the λ-mode, and when lighted in dimmer condition, the drive frequency is lowered to near the second resonance frequency f2 of the transformer 6 to allow it to make resonance and vibrate in the λ/2 mode. Even when the lamp load 2 is lighted in dimmer condition, a high efficiency at the same level as the lamp load 2 is fully lighted can thereby be maintained.

Abstract: PURPOSE:To obtain an inexpensive high speed relay circuit by using a complementary FET as an FET for gate storage electric charge discharge of an output MOSFET and providing a photo diode coupled to an input light emitting diode between gates of both the FETs. CONSTITUTION:When an input signal exists, a light emitting diode 1 is lighted, a photo diode array 2 gives a photoelectric electromotive force to turn on the output MOSFET 3.

The smectite is dispersed and swollen in a solvent to form a layer structure, which gives structural viscosity to the coating material itself. Thus, the obtd. electrophotographic photoreceptor causes no unevenness in the film thickness and shows high quality without image defects due to unevenness in the film thickness or without deterioration in electrophotographic characteristics due to whitening in a coating film, etc. The photosensitive layer is preferably formed as a function separation type layer comprising a charge producing layer and a charge transfer layer.  The charge producing layer is formed as a thin film of <5μm thickness, on which the charge transfer layer is formed to 10-35μm thickness by adding a smectite having dispersibility in an org. solvent to a coating material containing a binder resin. The amt. of the smectite is controlled to 0.1-10wt.% of the coating film weight after dried.

Filed: 1988-09-13
Abstract: PURPOSE:To enable a circuit board to be worked easily into desired outside dimensions by providing cut-off lines consisting of a plurality of elongated through holes and bridge sections between these holes while projecting the opposite ends of the adjacent elongated holes towards the region of the board to be contoured such that their imaginary extensions intersect each other. CONSTITUTION:Folding and separating grooves 2 formed along guide lines A and consist of a plurality of bridge sections 2a and elongated through holes 2b. The opposing ends of the adjacent elongated holes 2b are projected or bent at a certain angle towards a circuit pattern forming region 1a such that their imaginary extensions intersect each other. When the board is folded and separated along the grooves 2, each of the bridge sections 2a is cut off to make a cut-off plane which is naturally deviated from the predetermined cut-off line A to the side of the circuit pattern forming region 1a because the bridge sections 2a are located at a position deviated from the line A to the circuit pattern forming region 1a. According to this method, it is possible to obtain a circuit board having predetermined dimensions without leaving any projection at the bridge sections 2a in the process of cutting the board along the line A utilizing the grooves 2.
