Title: Positioning device for photosensitive drum
Inventor: NAKANO NAKAYA
IPC: B05C3/00
Filed: 1990-03-26
Abstract: PURPOSE:To position the photosensitive drum without scratching it and to retain an even clearance in the direction of periphery by providing a spraying means by which fluid is sprayed from a spraying opening which is substantially continuous in the direction of the periphery in the outside periphery of a cylindrical drum substrate and carrying out the positioning of the cylindrical drum by the fluid pressure. CONSTITUTION:The spraying means 3 by which positioning of the cylindrical drum 1 is carried out by the fluid pressure by spraying the fluid from the substantially continuous spraying opening 3a in the peripheral direction against the outer peripheral face is provided in a non coating position or an already coated position of coating liquid of the cylindrical drum substrate 1. Therefore, when the positioning of the cylindrical drum 1 is carried out, if air is sprayed from the surrounding of the drum 1, the position of the drum is neutralized by that spraying pressure, the drum can be positioned to a specified position, and the drum is not brought into any mechanical contact. At this time, the positioning can be carried out substantially continuous in the periphery direction against the outer peripheral face of the drum 1. Thus positioning can be carried out without scratching the drum, and the even clearance can be retained in the peripheral direction.

IPC: B23K26/38
Filed: 1986-04-02
Abstract: PURPOSE:To improve cutting quality by moving an impulsive high energy beam on a processing line at the relative moving speed satisfying special conditions to form plural pieces of holes, then repeating such processing. CONSTITUTION:Holes of one piece each per pulse are bored to a working material 1 such as printed circuit board by using the impulsive high energy beam and the pulse beam is moved along the processing line. the relative moving speed (v) of the beam is controlled within the range satisfying the conditions expressed by the equation with respect to the diameter (d) of the hole formed by the pulse beam and pulse frequency (f). The boring is then repeated twice and thrice until the material 1 is cut along the processing line. The processing is executed without contacting and the cutting is executed dividedly plural times and therefore, the deterioration in the material quality at the cutting point is prevented. The cutting quality and workability are thus improved.

Title: Water-intrusion monitoring system for composite cable
Inventor: WATABE JUNICHI
IPC: H02G1/10
Filed: 1990-03-28
Abstract: PURPOSE:To ensure the detection of the intrusion of water into a cable by monitoring the resistance value between a bare core wire provided in the composite cable and the water. CONSTITUTION:A composite cable 2 has control wires 2d, high-voltage wires 2e and coaxial circuits 2f in a cover 2b and a shield 2c.

Title: Power supply, discharge lamp lighting unit and lighting fixture
Inventor: SHIMIZU KEIICHI
IPC: H05B41/24
Filed: 1995-03-31
Abstract: PURPOSE: To obtain a variable output discharge lamp lighting unit. CONSTITUTION: During a period where the unsmoothed DC voltage rectified through a rectifier circuit 12 has a low peak value, a second FET Q2 is controlled to have a relatively long ON interval so that the resonance is maximized in the vicinity of zero crossing point where the current rectified through a rectifier circuit 12 has a lowest peak value and the voltage is stepped up more at a part where the unsmoothed waveform from rectifier circuit 12 is decreased thus smoothing the output. Consequently, the problem of too long ON interval can be solved even if the operating frequency increases in the vicinity of zero crossing point where the potential at the joint of resistors R1, R2 decreases to increase the duty ratio of the second FET Q2. Since the current phase is prevented from leading, the second FET Q2 has normal waveform thus preventing lowering of efficiency.  Furthermore, short circuit of first and second FETs Q1, Q2 is prevented during negative-phase recovery period of the parasitic diode.
