Title: Switching and connecting method for optical fiber connector
Inventor: TAMAKI YASUHIRO
IPC: G02B26/08
Filed: 1987-04-11
Abstract: PURPOSE:To shorten a switching time by connecting a first connector to a third connector from a second connector, while the first connector is moved in the array direction of the second and the third connectors. CONSTITUTION:While at least the first connector 1A is moved in the array direction of the second and the third connectors 1B, 1C, the first connector 1A is connected to the third connector 1C from the second connector 1B. In such a way, the communication stop time at the time of switching and connection can be minimized. Also, switching is executed by the operation for holding a fitting pin 5 for connecting a connector 1, and the operation for pressing the fitting pin 5, therefore, the switching can be executed without applying the external force to the connector 1 itself which is formed by a comparatively soft material such as a plastic formed part.

Title: Digital signal processing system
Inventor: MASUDA KOICHI
IPC: H04L27/06
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To provide a digital signal processing system which can reduce the influence of a communication signal that is caused to an AD-converted signal. SOLUTION: A data communication circuit 2 and AD conversion circuit 3 operate on the basis of the system clocks which are generated by a system clock generation circuit 1. The frequency of communication signal S1 of the circuit 2 is N/2 times as high as the sampling frequency of the circuit 3. The circuit 2 functions to control the phase of the signal S1 so as to set the amplitude of the signal S1 to 0 in a sampling mode of the circuit 3. Thus, it is possible to reduce the influence of the signal S1 that is caused to an AD-converted signal.

Title: Exposing device for copying machine
Inventor: MIYAMOTO JIYUNZOU
IPC: G03B27/54
Filed: 1984-05-07
Abstract: PURPOSE:To form an optimum image on a photosensitive surface by providing light distributing members to flash light sources and irradiating light more from both side edges thereby irradiating more light to the circumferential edge part of a platen than to the central part. CONSTITUTION:Platen glass 2 is provided in the upper part of a housing 1 and a pair of the flash light sources 6a, 6b are provided on the inside wall surface facing each other. Reflectors 7a, 7b are provided to the flash light sources 6a, 6b and the distributing members 20 are provided to the apertures of the reflectors 7a, 7b and are so opened that the more light is emitted from both side edge parts 23 than from the central part 21. The illuminance at the circumferential edge of the platen 2 increases when the light is irradiated from the light sources 6a, 6b to the platen 2. The light passes through an imaging lens 4 and is projected to the photosensitive surface 5. The image projected on the surface 5 is more uniform as the illuminance at the circumferential edge of the platen 2 is higher than the central part. The irradiation is made more from both side edges of the light sources than from the central part and therefore the optimum irradiating distribution is obtd.

Filed: 1979-07-14
Abstract: PURPOSE: To make it possible to move a body to be detected while discriminating its direction, by facilitating installation construction and also by simplifying the structure of a projection-photodetection part by constituting a projection part and photodetection part in one body.  
     CONSTITUTION: Light emitting elements 2 1  and 2 2  of projection part 7 provide light modulation with the output of modulating oscillator OSC1. To discriminate objective light from other natural light, driving circuit 10 is controlled by the output of oscillator OSC2 to supply the output of OSC1 to elements 2 1  and 2 2  by turns. At photodetection part 8, photodetector 4 detects reflected light of projected light from detected body 5 and its output is supplied to signal processing circuit 9 after amplification 11. Circuit 9, supplied with the output of OSC2 as well, discriminates between projected light from element 2 1  and that from 2 2  at its timing and then detects changes of photodetection signals to decide the existence of detected body 5. Further, its moving direction is decided by discriminating the order of the photodetection signals.

Title: Lead storage battery
Inventor: NODA TADASHI
IPC: H01M10/14
Filed: 1982-05-25
Abstract: PURPOSE:To obtain light weight and reduce a strap welding process by perforating cuts of a number of expanded plates filled with active materials and combining them. CONSTITUTION:In positive and negative plates, 1 and 4 are plate lugs and 2 and 5 are strap substitution sections. 3 and 6 are positive and negative electrode active materials. Shortcircuit is fully prevented by bending and combining the positive and negative electrode plates along cuts and packing the negative electrode plate with an envelope separator 9. As a result, after the initial performance and life performance are checked, a lead storage battery can be made lightweight in wet weight by removing a strap section and the result that equals or exceeds the conventional initial performance and life performance is obtained.

Title: Gas discharge lamp electronic ballast circuit with improved power factor and lamp efficiency
Inventor: DEAVENPORT JOE E
IPC: H05B41/24
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To improve power factor and reduce peak factor by subjecting an input current to a specified wave-shaping. SOLUTION: A wave-shaping network 20 and a resistor 27 are constituted so that a peak of a lamp current flowing through an N-channel transistor 29 and a primary winding follows a flat, full-wave-rectified sine wave. When the average of the peal of the current to a lamp resonance circuit varies, the peak amplitude of the flat, full-wave-rectified current flowing from a rectifier bridge 11 also varies. However, such a peak amplitude, if the pulse width of the gate control output of a pulse modulation circuit 25 is constant, is always smaller than a full-wave-rectified sine wave current which would otherwise flow from the bridge 11. Since the current flowing from the rectifier bridge 11 has the full-wave-rectified waveform at a node 104, the power factor of the ballast circuit is improved. Also, such a current wave-shaping reduces the peal factor.
