Title: Recording paper processor
Inventor: MAEKAWA ETSUICHI
IPC: G03G21/00
Filed: 1987-05-29
Abstract: PURPOSE:To facilitate recovering operation of jamming by providing means for detecting finish of recovering operation and providing the output from aforementioned means as a starting signal of recording operation. CONSTITUTION:When first part of copy papers are being binded through a processing unit 1, an automatic document circulation feeder 3 feeds documents for second part copy papers sequentially with such timing as the output from a paper discharge sensor at tray transmits from ON to OFF. Consequently, a copy machine 2 carries out copying operation through similar electrophotographic process as that which is employed for the first part copy papers. Consequently, recording of second part copy papers is started after the first part of copy paper has been binded completely and immediately before they are discharged. Since first part of copy papers has already been contained in a containing tray 46, jamming of second part of recording paper can be eliminated by simply removing second part of recording paper placed in the copy machine 2, resulting in simplification of recovering operation.

Title: Overcurrent detector
Inventor: OONISHI YUUSAKU
IPC: G01R19/165
Filed: 1978-10-26
Abstract: PURPOSE: To eliminate the repetition of a detection "on" and no detection "off" in the detector by providing a hysteresis characteristic, the level of which is equal to or more than the input ripple voltage, to said voltage.  
     CONSTITUTION: When the main circuit line 1 is normal, the output is "1" since the input to the comparator 13 is lower than a reference voltage, and the transistor 16 is "on". The capacitor 18 is not charged and the output of the comparator 20 is "0". When overcurrent flows in the main circuit line 1 and input voltage to the comparator 13 exceeds a reference voltage, the transistor 16 is turned off, the capacitor 18 begins to be charged. At the same time, because the output of the comparator 13 becomes "0", the reference voltage is changed, a reference voltage to the input voltage of the comparator 13 changes. In this way, a hysteresis characteristic the level of which is equal to or more than the input ripple voltage can be provided to the said voltage.

Title: Constant volume feeding method of molten solder
Inventor: KOUSAKA MASARU
IPC: B23K3/06
Filed: 1978-10-25
Abstract: PURPOSE:To enable stable soldering to be performed without any supply defect by  supplying solder to the vertically moving nozzle comprising being built in with a  heating heater and having openable end thereby opening the nozzle end as it  descends and letting the molten solder flow down. CONSTITUTION:The end of a nozzle 11 is heated with a heater 15 and with the  end of the nozzle being held closed the nozzle 11 is positioned to the ascending end.  Next, one solder particle 12 is supplied to the nozzle 11 from a solder feeder 19 and  is melted at the end part. Thence, the nozzle 11 is lowered and at the same time the end is slightly opened to let the molten solder 12 become ball-form at the end. The nozzle 11 is then further lowered and the molten solder 12 is contacted to the stem 13 which has been heated and has been carried to the specified position by a conveying jig 16. Since the stem 13 has been heated, it lets the molten solder 12 flash with a good fit. Following to this, the foregoing process is repeated and the  flashed solder is evenly spread by a round bar or the like, thence a pellet is mounted.

Title: Motor drive circuit
Inventor: OKADA NORIAKI
IPC: H02P6/12
Filed: 1998-05-14
Abstract: PROBLEM TO BE SOLVED: To prevent a motor kickback being generated in relation to switching full-waves and half-waves. SOLUTION: A speed detecting circuit detects the r.p.m. of a motor from a Hall FG signal produced from a Hall comparator based on a Hall waveform signal and delivers a speed detection signal indicative of the r.p.m. of a motor exceeding a specified value to a full-wave/half-wave switching circuit 14. At the time of full-wave/half-wave switching, the circuit 14 generates a drive-off signal which is delivered to an output stage 16 along with a full-wave/half-wave switching signal. The output stage turns the driving current off at the time of fullwave/half-wave switching.

Title: Treatment of arsenic sulfide precipitate
Inventor: OKAJIMA YASUHIRO
IPC: C01G28/00
Filed: 1979-10-13
Abstract: PURPOSE: To convert an arsenic sulfide precipitate into a dense solid substance easy to handle by covering the surface of the precipitate put in a container with a metallic iron-contg. substance after which the precipitate is melted and cooled.  
     CONSTITUTION: An arsenic sulfide precipitate is put in an open container, and after covering the surface of the precipitate with iron dust or a metallic iron-contg. substance, the whole container is heated to the m.p. of the precipitate or above to melt the precipitate. This melt is then converted into a dense solid substance by cooling to ordinary temp. When the precipitate is melted, part of it reacts with the covered iron to form a compound layer of iron sulfide and iron arsenide. This layer is dense and forms a lidlike composition in the container. Partially volatilized arsenic sulfide reacts with iron and is captured as compounds similar to said ones.
