Title: Image recorder
Inventor: NAGASHIMA KANJI
IPC: G03B27/54
Filed: 1994-03-18
Abstract: PURPOSE:To secure a large quantity of transmitted light and to obtain excellent image quality even in the case of overexposed negative film by arranging a condensing lens on the optical axis of an image-formation lens near a light source and positively condensing light directly made incident on a diffusing plate from the light source. CONSTITUTION:The condensing lens 24 having a focal point at nearly the same position as the light condensing member of an elliptical mirror 18a is arranged between the light source 16 and the diffusing plate 20 in an image recorder 10. As a result, the light directly going toward an original G from the light source, which is wasted in the conventional manner, is condensed and vertically made incident on the diffusing plate 20 and the original G through an optical path along an optical axis L. Therefore, the sufficient light quantity is secured, so that the image is excellently recorded even in the case the original G is overexposed. Furthermore, even when the original G is scratched or gets dirty, the image is recorded with optical image quality in a state where the scratch or the dirt is made inconspicuous by diffused light by the diffusing plate 20.

Title: Combustion system for processing industrial waste material
Inventor: AONO HIDEYASU
IPC: F23G5/16
Filed: 1987-03-05
Abstract: PURPOSE:To prevent a toxic gas from being discharged by a method wherein a first combustion chamber having an ignited material feeding port and an air feeding port at a furnace ceiling, a second combustion chamber overlapped over the first combustion chamber and having an air supplying port at the furnace ceiling and a dust collecting chamber guiding combustion discharged gas into a chimney to collect powder dust are provided. CONSTITUTION:For example, when chips of fiber reinforced plastic FRP are to be ignited, they are fed into a first combustion chamber 7 up to a height of a bottom part of a second combustion chamber 8, only an air supplying port 61 is released and then an ignition is made. As the combustion is advanced, air supplying ports 62 and 63 are released to open in sequence. As the combustion is excessively performed, a wave-like air flow is generated within the combustion chamber 7 and the chips are gradually ignited from its upper surface layer to its core part. Under this condition, an air supplying port 64 of the combustion chamber 8 is released and the combustible gas which is not completely ignited within the combustion chamber 7 is ignited substantially completely within the combustion chamber 8. The combustion gas from the combustion chamber 8 may accept an action of cyclone and then a slight non-ignited material contained in it is collected and then accumulated at the bottom part of the dust collecting chamber 9. The waste gas after dust collection has no bad odor and soot at all.

Title: Picture reader
Inventor: TAKASAKI YOSHIMI
IPC: H04N1/40
Filed: 1989-03-01
Abstract: PURPOSE:To improve processing capacity for each unit time by providing a computing element to input the output signal of an optical detector, to calculate an n-power root of the output signal, converting the root to a signal in the desired input signal range of a logarithmic amplifier and to output the signal to the logarithmic amplifier. CONSTITUTION:A computing element 25 is provided to input an output signal S1 of an optical detector 21, to calculate the n-power root (n>1) of the output signal S1 and to output the root to a logarithmic amplifier 26. Thus, the range of the input signal is compressed by the computing element 25 and only the range of a satisfactory responding characteristic in the logarithmic amplifier 26 is used. Then, even when the speed of reading is made high, logarithmic conversion is executed with enough accuracy. For a signal S to which logarithmic compression is executed after the n-power root is calculated with passing through the computing element 25, since a signal value is only made 1/n-fold is comparison with a signal S', to which the logarithmic compression is executed without passing through the computing element 25, complicated arithmetic is not required for the correction. Thus, even to the weak input signal, the processing capacity can be improved for each unit time.

Title: Repeater
Inventor: KIKUTA RUMIKO
IPC: H04L69/14
Filed: 1997-03-04
Abstract: PROBLEM TO BE SOLVED: To provide an optimum relay amount corresponding to the throughput of respective devices for relaying a network by providing a judgement means for judging whether to relay the request from a first line to a second line or to relay it through the first line to the other relay device from the relay conditions of the device and the other repeater. SOLUTION: In the case of setting the priority of this repeater higher than the other repeater (the repeater 1 for instance), the repeater 1 relays the relay request to the second line 20 when the threshold value of the repeater 1 does not exceed an upper limit and the relay request is relayed through the first line 10 to the other repeater having low priority (the repeater 2 and 3 for instance) when the threshold value of the repeater 1 exceeds the upper limit. In the case that the priority is low (the repeater 2 for instance), when the other repeater having the highly priority, the repeater 1 for instance, does not exceed the upper limit of the threshold value of the repeater 1, the repeater 2 relays the relay request through the first line 10 to the repeater 1.

Namely, the parts close to the leading parts of the fibers 6, 8 are worked like tapers and the leading parts are semispherically worked as so-called taper top spherical fibers, so that the increment of an insertion loss can be suppressed. Thus, the optical fiber type polarized wave separator reduced in insertion loss and ensured easy production can be obtained.

IPC: H02M3/07
Filed: 1987-03-04
Abstract: PURPOSE:To protect a MOS transistor against a damage by detecting the abnormal drop of an output voltage to switch the connection of the substrate terminal of an output MOS transistor. CONSTITUTION:The substrate terminal of an output MOS transistor (Tr) 20 is connected to the mutual connection point of two MOSTrs 31, 32 of a substrate switching circuit 30 designated at the output terminal. The Trs 31, 32 are used for switching the substrate terminal of the Tr 20 to alternately turn ON in response to the output state of the comparator 41 of a malfunction detector 40. An inverter 33 in the circuit 30 operates to alternately turn ON. Thus, when the value of the output voltage V0 decreases lower than a threshold value due to the short-circuit of a load 3, the comparator 41 generates a malfunction detection signal to turn ON the MOS Tr 31 of the circuit 30 and to turn OFF the Tr 32 to switch to connect the substrate terminal of the Tr 30 to the capacitor side terminal.

Title: Automatic focus adjusting device
Inventor: TAMEKUNI YASUHIRO
IPC: G03B13/36
Filed: 1990-02-28
Abstract: PURPOSE:To preclude an overshoot due to the response delay of infocusing averaging decision by performing an averaging process only when a lens is in focus and stabilizing the lens in the focusing state, and performing lens control based upon the result of the averaging process when the lens moves from a defocusing state to the focusing state. CONSTITUTION:An electric signal corresponding to the quantity of light made incident on a sensor 4 is processed by an amplifying circuit 5, a detecting circuit 6, and an integration circuit 7 to input information to a microcomputer 9 through a comparing circuit 8. The microcomputer 9 decides the focusing or defocusing state according to the input information and controls a motor driving circuit 10 to drive a motor 11, thereby adjusting the focus automatically. In this case, the focusing decision based upon the averaging process result is carried on until the defocusing state is decided after focusing is decided once. Consequently, the lens can be held stably in the focusing state and the focusing decision based upon the averaging process result is not made in the defocusing state, so the overshoot can be precluded.
