Title: Control method for developing device of image forming device
Inventor: MATSUURA MASAMI
IPC: G03G15/06
Filed: 1985-08-29
Abstract: PURPOSE:To prevent image density from decreasing and toner from being wasted by applying a developing bias to the developing electrode of an unselected developing device in such a direction that toner is hard to develop. CONSTITUTION:When the unselected developing device is a normal developing device 20, a developing sleeve 21 is put away from a development area Yb and a developing bias nearly equal to the potential of an electrostatic latent image is applied to the developing electrode 22. In this case, the toner in the developing device 20 is triboelectrified to the opposite polarity from the electrostatic latent image potential, but the developing bias is substantially zero V, so no toner sticks on an electrostatic latent image carrier. Further, when the unselected developing device is a reversal developing device 10, a developing bias nearly equal to the earth potential is applied to the developing electrode 11. In this case, the toner in the developing device 10 is triboelectrified to the same polarity as the electrostatic latent image potential, but the electrode 11 is grounded, so no toner sticks on the electrostatic latent image carrier. Thus, a decrease in image density and a waste of toner at the time of a change in developing mode are eliminated.

Filed: 1994-08-15
Abstract: PURPOSE:To adjust a load by regenerating excessive power which is not applied to a load circuit among power to the secondary side of a transformer in a DC power supply by switching. CONSTITUTION:A switching element SEQ1 is constantly switched on the primary side of a transformer T1 in specified conditions, so a larger power than the maximum value of power to be applied to a load circuit is supplied to the secondary side, and allowance power which is not applied to the load circuit is used for switching SEQ2 on the secondary side of the transformer T1 to be regenerated in a DC power supply, so load circuit conditions are detected by a potential on the secondary side of the transformer T1 to adjust supply power to the load circuit by controlling SEQ2 in accordance with result. Stress applied on the SEQ1, Q2 can be reduced by alternately switching the SEQ1, SEQ2 in the period where a current is not supplied to windings of the transformer T1.

Title: Gas laser equipment
Inventor: NOZUE YASUHIRO
IPC: H01S3/03
Filed: 1996-07-22
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of operating efficiency of a laser equipment by quickly exchanging one laser head for another when the one laser head gets out of order and stops, by mounting a laser head for gas excitation on a transfer stand, and making the head movable in the direction almost rectangular to the optical axis. SOLUTION: In an excimer laser equipment 1, a laser resonator 2 which determines the optical axis of laser light and a laser head 3 which generates laser medium by discharge are retained independently of a machine frame 4. The laser head 3 is installed on the machine frame 4 in such a manner that it can be detached in the direction rectangular to the optical axis. At least two laser heads 3 of the same type are prepared and mounted on a transfer stand which is movable to the machine frame 4. When the laser head 3 set on the optical axis must be stopped, the laser head 3 is moved outside the machine frame 4 by rotating or sliding the transfer stand. Another head 3 is set on the optical axis and operated.

Title: Jump-back processing circuit for optical disk device
Inventor: MACHIDA TAKASHI
IPC: G11B21/08
Filed: 1987-07-30
Abstract: PURPOSE:To attain a stable jump-back action by providing a jump-back trigger generator to generate a jump-back trigger signal in a prescribed timing. CONSTITUTION:A jump-back trigger generator 5 counts a spindle clock signal S2 by a clock counter and generates a sector clock signal which is a signal having the same period, namely, the same frequency as a sector timing signal S11. The clock counter forcibly sets a count value by the sector timing signal S11 and thus, the matching of the timings, in other words, the phases of the sector timing signal S11 and the sector clock signal is executed. A sector counter, as well, forcibly-sets a counter value into the value of a sector code signal S10 and thus, the sector counter synchronizes with the sector timing signal S11 and the sector code signal S10. Thus, since an action to read out ID information is always executed and it is unnecessary to recognize a sector number, a trigger signal to execute the stable jump-back action can be generated.

IPC: B65G47/28
Filed: 1985-08-31
Abstract: PURPOSE:To accomodate sweets or the like uniformly in a receptacle, and to improve the efficiency in an apparatus for putting sweets or the like in a conveyed receptacle and conveying same by oscillating the receptacle in the lateral direction of a conveyer with a larger amplitude as the receptacle advances. CONSTITUTION:Sweets W or the like are collected in a collecting hopper 3 from the respective measuring hoppers 2, and supplied to conveyed receptacles 12. Oscillating plates 29, 30 are oscillated by a motor 34, whereby both side surfaces of the transported receptacles 12 are brought into contact with the oscillating plates 29, 30, so that the receptacles are oscillated in the lateral direction of receptacle holders 21. The amplitude of the oscillation becomes larger as it goes to the carry-out side. In this arrangement, at the time of heaping just after putting sweets in the receptacle 12, the receptacle is oscillated with a smaller amplitude to prevent overflowing of the sweets, and as the heap becomes lower, the receptacle is oscillated with a larger amplitude to accomodate the sweets stably and uniformly inthe receptacle 12. Thus, the efficiency can be improved.

Title: Surface emitting light source
Inventor: ISHII KENICHI
IPC: F21V8/00
Filed: 1998-07-08
Abstract: PROBLEM TO BE SOLVED: To achieve a long life, to uniform luminance and to expand a light flux, by providing a heat conductive plate having one end connected to a heat sink so as to be able to transmit heat and plural LED elements covered by an electrical insulating material layer placed on one side through an insulating material, and a thin sheet diffusion transmission layer disposed apart from the one side. SOLUTION: An LED element 4 generates heat by electrically energizing it and its temperature rises. The heat is transmitted to a heat conductive plate 1 through an electrical insulating material 3, and is dissipated to the atmosphere from the side of heat sink 2 fixed to one end of the heat conductive plate 1. Since the heat resistance of the heat conductive plate 1 is small, the heat coming out of the LED element 4 is efficiently discharged outward, and as a result, the temperature of the LED element 4 is suppressed at a low level. Light emitted from the plural LED element 4 does not form a flat surface light source having uniform luminance as a total, because the LED elements 4 are discontinuously disposed, however its luminance is averaged out by diffusion transmission if it reaches a diffusion transmission layer 6 positioning externally.

Abstract: PURPOSE:To analyze the components in a material to be measured accurately, by obtaining the transmittances of a plurality of radiations, whose energy ranges are different, based on a radiation source, which generates both high-speed neutrons and gamma rays, a detector of both radiations, which have transmitted through a material to be measured, and signals from the detector. CONSTITUTION:A <252>Cf radiation source 10, which generates both high-speed neutrons and gammarays, is enclosed in a storing container 12. The radiations are suitably converged and projected on an object to be analyzed 18 on a belt conveyer 16 as radiation flux. The neutron beam 20 and the gamma rays 22, which have transmitted through the object 18, are detected by an organic scintillator 26 in a collimator 24, which is also used as a shield. The output of the scintillator 26 is made to pass through a photomultiplier 28 and a preamplifier 30. At first, one signal is guided to a pulse waveform discriminator 32, and either a high-speed neutron signal 34 or a gamma-ray signal 36 is generated. The other signal is made to pass through a linear amplifier 38 and a delay amplifier 40. Then the output of the amplifier 40 is guided to linea gate parts 42 and 44. The neutron beam becomes linear pulses 46 through the gate 42, and the gamma rays become linear pulses 48 through the gate 44. The values of the pulses 46 and 48 observed by the wave height analyzers 50 and 54 are computed by an operator 52, and the amounts of components are obtained. Thus the measurement can be continuously carried out.
