Title: Image forming device
Inventor: KUROKAWA HIROTO
IPC: G03B27/62
Filed: 1988-12-02
Abstract: PURPOSE:To detect a document on platen glass speedily without making the device complex by inhibiting a document feeding and discharging device from being driven until nonclamping and clamping by an original platen cover are detected again after nonclamping and clamping are detected. CONSTITUTION:After a detecting means 118b detects the nonclamping and clamping of a document by the platen cover 51, the document is supplied from a 1st stack part onto an original platen 12 and the original feeding and discharging device 3 which discharges the document to a 2nd stack part is inhibited from being driven until next nonclamping and clamping are detected. The document on the original platen is detected speedily without making the device complex. Consequently, even when the document is left forgetfully on the original platen glass 12, automatic document feeding (ADF) operation is inhibited, so the occurrence of a jam can be prevented.

Title: Pwm inverter device
Inventor: NISHIZAWA YUJI
IPC: H02M7/48
Filed: 1988-12-02
Abstract: PURPOSE:To suppress heat generation of a current detector by a method wherein a capacitor is connected in parallel in a series circuit of the current detector and a coil so that recovery current of an output switching element flowing in the current detector is reduced. CONSTITUTION:The instance an output switching element 5 is turned on, step voltage Vdc is applied to a reflux diode and a current detector 4, and the reflux diode is replaced by a capacitor of capacitance C1 at this moment. The detector 4 is represented by equivalent resistance R1 for generating loss. A bypass capacitor 7 is represented by C2 while current I1 flowing in the detector 4 is expressed by two specified formulae. Since this current I1 is reduced in this equivalent circuit as expressed by current I1=(Vdc/R1){C1/(C1+C2)} when voltage Vdc is applied, current flowing in the detector 4 is reduced. Although this extends time constant, heat generation of the detector 4 can be reduced since loss of the detector 4 is in proportion to square of current I1 as expressed by (I1)<2>.R2.

Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To provide a technique for polishing a work with a good yield and high precision. SOLUTION: A plural carriers 18 each of which has a fixed lower plate 11 provided with a lower-side grinding stone 12 and a fixed upper plate 13 provided with an upper-side grinding stone 14 to hold a work W, are engaged with sun gears 15 and internal gears 16. After polishing with both grinding stones 14, 12 is completed, before the fixed upper and lower plates 13, 11 are stopped, the sun gears 15 are stopped, thus to form a drawn-line on the surface of the work W. On the other hand, after the polishing is completed, the upper and lower fixed plates 13, 11 and the sun gears 15 are stopped at almost the same time, thus not to form the drawn-line. A drawn-line mode to form the drawn-line and a non-drawn-line mode not to form the drawn-line can be selected by an operator. When drawn-line work is done, the working amount can be randomly set.

Title: Powdery deodorant and its production
Inventor: TOMARU MASAHIDE
IPC: B01D53/38
Filed: 1992-10-19
Abstract: PURPOSE:To produce powdery deodorant having suppressed deliquescence. CONSTITUTION:A raw material for a deodorant, for example, comprising a fungicide, an organic acid, perfume, dye and a moisture absorption inhibitor is uniformly dispersed and blended in a blender 11 by a mixing and rotating blade 23, granulated by using the perfume or the moisture absorption inhibitor as a binder or bulk produced during the granulation is ground by a crushing rotary with 31 into a state of the surface of the granulated power coated with the moisture absorption inhibitor. Since a deodorant comprising the granulated powder coated with the moisture absorption inhibitor thus produced has extremely less contact between the raw material having high hydroscopicity and the atmosphere, the deodorant hardly absorbs moisture, consequently, deliquescence is suppressed to reduce solidifying properties as the result, of the less contact between the raw material and the atmosphere.

Title: Operation of gasification melting furnace of waste
Inventor: SUDO MASAHIRO
IPC: F23G5/00
Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To obtain solid granulated matters so as to reduce the volume of fly ashe by granulating dust which is generated at the time of operating a melting furnace for gasification of waste or solidifying the dust into a briquet shape at a specific water content, and feeding it back again to the melting furnace. SOLUTION: An exhaust gas containing dust generated at the time of operating a melting furnace 1 which is used for melt treatment of waste, such as city refuse and shredder dust, is treated through an exhaust gas treating facility 2 and a dust collector 3. The dust which has thus been caught and collected is recovered at a storage tank 4. The dust in the tank 4 and slaked lime in a slaked lime storage tank 5 are supplied, together with water, to a kneading and granulating machine 6 by conveyers 4a, 5a, followed by kneading and granulating treatment (or formation of briquets) at water content of 5-20%. Thus obtained granulated matters are fed back to the melting furnace 1 for melt treatment.  In this way, physically solid granulated matters can be obtained and hence, it is possible to reduce the volume of fly ashes and the amount of slaked lime used as a secondary material without drastically enlarging a treating system.

Title: Ultrasonic wave probe
Inventor: HAYAKAWA YASUO
IPC: G10K11/30
Filed: 1987-12-07
Abstract: PURPOSE:To obtain a stable S echo at a high level without collapse of a waveform, by arranging another vibrator at a position closer to the end surface of a case than a vibrator, in parallel with the surface of the vibrator, in the case. CONSTITUTION:Flaw detection is performed at a specified depth from the surface of a specimen with a probe P. At this time, a vibrator 1 and a vibrator 6 are arranged at the different planes in the probe P. Therefore, at first an echo S1 of the waveform of a detected flaw from, e.g., the vibrator 6 is displayed. Then an echo S from the vibrator 1 is displayed. Since the propagating distances of the echo S1 and the echo S are different, the echoes are separated without fail and without overlapping. With respect to the echo S1, the ultrasonic wave, which is projected from the vibrator 6, is sent and received through a part other than a lens surface 7a of an acoustic lens 7, even if the distance between the specimen and the probe P is changed. Therefore, the stable waveform at a high level without collapse of the waveform is obtained as in the case of an ordinary vertical probe.

The bending or lateral run-out vibration of the drive axis can be prevented and a high speed action is permitted by thus providing the brake device on the anti-drive axis side of the piston.
