IPC: G03G15/01
Filed: 1985-05-24
Abstract: PURPOSE:To prevent a mirror for reflected light by an original from the adhesion of dust or the like and to prevent picture quality from deterioration by arranging respective exposing parts of plural image forming means on some positions of the upper half periphery of a photosensitive body. CONSTITUTION:A beam (a) projected from a laser scanner unit 310 is irradiated from a position almost right above the photosensitive body 301 to the surface of the photosensitive body 301 at the exposing through a reflecting mirror 311 part 350 located between an electric charger 302 and a developing unit 303. On the other hand, a beam (b) is irradiated to the surface of the photosensitive body 301 through reflecting mirrors 312, 313 at the exposing position located between an electric charger 304 and a developing unit 305. The beams (a), (b) are reflected by the mirrors 311 or 312, 313 through an f.theta lens 320 to expose the surface of the photosensitive body 301 and form an electrostatic latent image. In this case, the exposing parts 350, 351 are arranged on the upper half peripheral area A of the photosensitive body 301. Consequently, the mirror 311 is turned downward and prevented from the adhesion of dust or the like.

Title: Luminance controller
Inventor: HIGO MOKICHI
IPC: H05B39/04
Filed: 1984-06-04
Abstract: PURPOSE:To obtain a luminance controller that can control the luminance of light emission with high accuracy by storing a change pattern of said luminance to a memory means in the form of a table and performing the conversion based on the table to change the luminance. CONSTITUTION:When a knob of a variable resistor 100 is set properly, the corresponding voltage is supplied to an A/D converter 102 and converted into the digital signals to be supplied to the ROMs 104 and 106. The ROM104 uses the input digital signal as an address signal, and the data stored in the addresses of a conversion table are delivered to a D/A converter 108 to be converted into the analog signals. These analog signals are amplified by an amplifier 110 and applied to a light emitter 22A for emission of light with the corresponding luminance. Therefore the relation between the knob of the resistor 100 and the luminance of the light emitter 22A can be changed by setting properly the conversion table of the ROM104. In addition, the conversion is carried out in the same way for light emitters 22B and 22C by the conversion table by means of the ROM106, a resistor 112 and an oscillator 114.

IPC: H01L21/52
Filed: 1995-04-14
Abstract: PURPOSE: To form a solder layer for bonding a pellet with uniform thickness while eliminating void therefrom. CONSTITUTION: When a collet 14 containing a vacuum sucked pellet 12 is mounted on the header 10 of a lead frame 1, a gap 18 is formed between the pellet 12 and the header 10. Molten solder 17 is then fed into the gap 18 through an injection tube 19 coupled with an opening made through the side wall of the collet 14. The air in the gap 18 is pushed out by the molten solder 17 through an air vent 20 made through the side wall of the collet 14. Since the gap is sustained constant by the collet at the time of feeding the molten solder, a solder layer having uniform and constant thickness can be formed. Furthermore, void can be eliminated from the solder layer, because the air in the gap is pushed out by the molten solder.

Abstract: PROBLEM TO BE SOLVED: To provide the sigma delta type D/A converter of high quality which is suppressed in the adverse effect of a phase shift between a sample clock and a noise shaper clock. SOLUTION: A prefetch register 1 is provided right before a previousvalue hold register 3 which perform oversampling for a noise shaper part and a phase shift part 2 switches the phase of the operating clock of the prefetch register 1 according to the phase difference between a sample clock and a prefetch clock to vary the substantial oversampling rate of the previous-value hold register 3. Consequently, the generation of distortion when the sample clock and noise shaper clock do not synchronize with each other can be suppressed to a practical level. Consequently, the sigma delta type D/A converter is usable even for uses which were impossible because of the problem of clock jitters.
