Title: Cleaning device for electrophotographic copying machine
Inventor: TSUKAMOTO TSUGIO
IPC: G03G21/10
Filed: 1983-10-04
Abstract: PURPOSE:To enable the detection of contamination in a copying machine owing to toner clogging and the deterioration of image quality in early time by combining a timing disc attached to the shaft of a rotary valve or auger with an encoder and generating a pulse. CONSTITUTION:The toner captured by a cyclone enters an auger 3 via the lower part 1 of the cyclone and a rotary valve 2. An encoder 8 is combined with a timing disc 7 attached to the top end of the extension shaft of an auger shaft 4. If the toner is clogged in the valve 2 or an auger pipe 5, the disc 7 rotates irregularly. The toner clogging can be therefore known in early time by detecting the decrease in the number of the pulses generated by the encoder 8. The adverse influence of the toner clogging on the function of the copying machine and the image is prevented.

Title: Automatic transcription device
Inventor: MOCHIZUKI KAZUHIRO
IPC: G10G3/04
Filed: 1993-07-27
Abstract: PURPOSE:To prevent the automatic transcription device, which converts a sound signal such as a voice and a musical instrument sound into music data, from identifying a wrong interval under the influence of a part where the interval is unstable at the time of sound generation and transition to a next sound when one interval is identified for a section that can be regarded as one sound. CONSTITUTION:An interval identifying processing is constituted by using a means 131 which calculates the distance between a candidate for an interval to be identified and actual pitch information, a means 132 which determines a weight coefficient according to a position in the section, a product sum calculating means 133 which calculates the sum of products of said distance and weight coefficient corresponding to respective pieces of pitch information in the section, and an interval determining means 134 which identifies the interval candidate having the least calculated product sum value as the interval in the section. The means 132 which determines the weight coefficient is so set that small coefficient values are obtained nearby the head and tail of the section, and then the effect of the interval on the interval identifying processing for the unstable interval part is reduced to enable more accurate identification.

IPC: G01L3/10
Filed: 1987-07-24
Abstract: PURPOSE:To eliminate the generation of an error caused by a variation of an ambient temperature, by providing a correcting means for outputting a signal corresponding to a signal of an exciting current value from a detecting circuit. CONSTITUTION:By exciting coils 4a, 4b, a magnetic flux is applied to an axis 1 to be measured. In this state, when a torque is applied to the axis 1 to be measured, the magnetic flux in the axis 1 to be measured is varied. A detecting coil 5 detects its variation and outputs the corresponding output signal. The signal is amplified 7, rectified 8 and inputted to an arithmetic circuit 9. Also, when an exciting current 6 flowing to the exciting coils 4a, 4b is varied due to a variation of an ambient temperature, the variation of the current is detected by an exciting current detecting means 11, and inputted to an arithmetic circuit 18. On the other hand, a signal from a variable resistance 13 is also inputted to the circuit 18. Subsequently, the circuit 18 operates a difference of both the signals and outputs a signal corresponding to the detected value. This signal passes through a correcting element 19 and is inputted as a correcting signal to the arithmetic circuit 9. In such a way, the generation of an error caused by a variation of an ambient temperature can be eliminated.

Title: Manufacture of color cathode-ray tube
Inventor: KOJIMA TOSHIHISA
IPC: G03F7/28
Filed: 1987-07-25
Abstract: PURPOSE:To prevent a phosphor screen from discoloring and to improve strength of a phosphor layer by making metyl amine vapor touch a phosphor coated layer with phosphor particles received and in succession by making steam touch there. CONSTITUTION:When aromatic diazonium salt/zinc chloride complex salt is used as a photosensitive component, the complex salt is first decomposed by light rediation to liberate the zinc chloride. The liberated zinc chloride is a high hygroscopic substance. When this zinc chloride is made to touch metyl amine vapor and steam, it is changed into zinc hydroxide and becomes insoluble to water so that a phosphor layer with sufficient strength can be formed for a short time. Hence a discoloring region due to impurities can be effectively prevented from being enlarged, and further strength of the phosphor layer can be improved.

Title: Treatment of waste water containing metal and ammonia
Inventor: SOGAWA TETSUYA
IPC: B01J33/00
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To separate and remove metals in waste water and to prevent the lowering of the performance of a noble metal carrying catalyst by bringing the waste water into contact with a chelate resin or an ion exchange resin, separating metal hydroxides deposited by adjustment to a specified pH range and then bringing the waste water into contact with the catalyst under coexistence of oxygen-containing gas. SOLUTION: Waste water is passed through a resin packed tower 3 packed with a chelate resin or an ion exchange resin to remove prescribed metal ions and metals are deposited as hydroxides in a storage tank 4 by adjustment to pH 8-12 with alkali. The water containing the deposited metal hydroxides is subjected to solid-liquid separation in a filter 6.

Title: Driving method of discharge display panel and display device
Inventor: SASAKI TAKASHI
IPC: G09G3/292
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a malturning on in a sustain discharging period and to obtain a high quality picture by erasing charged particles formed by maldischarging caused by selection reset pulses with the application of other selection reset pulses. SOLUTION: In a sustain discharge period, a display cell, on which sustain discharge 44 is not generated, may conduct discharge 45 by a first selection reset pulse 1. If self erasing discharge such as discharge 42 has not occurred under this condition and a second selection reset pulse 5 is applied to a Y electrode, discharge 46 occurs by the rise of the pulse 5. When a third selection reset pulse 2 is applied under this condition, discharge 47 occurs by the rise of the pulse 2, self erasing discharge 48 is generated after the fall of the pulse 2 and wall electric charges are erased. Since no discharge takes place for the display cell during a sustain discharge period, degradation in picture quality caused by the maldischarge 45 is prevented.

Title: Amplifier circuit
Inventor: YOSHIOKA ISAYUKI
IPC: H03G3/10
Filed: 1991-07-25
Abstract: PURPOSE:To suppress the fluctuation of an output voltage caused at the time of alternating an amplification factor by giving cancellation current cancelling the current fluctuation expressed in load resistance when the current of a constant current source is changed so as to change the amplification factor. CONSTITUTION:The emitter current I3 of a transistor Q3 in a counterbalance current generating part 41 flows through the load resistance RL of a differential amplifier besides current Io/2. The current I3 is made to be the same as current I flowing through the emitter of the transistor Q3. The value of current I2 is decided by the voltage VR of a reference voltage source 5, the control voltage Vc and resistance R2. Therefore, the voltage between the base and emitter of the resistor Q2 and the voltage between the base emitter of the transistor Q3 come to be always equal so that the value of current I2 is not affected by the fluctuation due to the current change of the voltage between the base and the emitter. Current Io flowing through the differential amplifier is stable since the alternation factor is small as against the alternation factor of current I2. Thus, amplifier circuit which is superior in the stability of the output voltage vo at the time of alternating the amplification factor is obtained.
