Title: Phosphate-contg. water disposal
Inventor: JIYOUKOU ISAO
IPC: C02F1/58
Filed: 1982-08-02
Abstract: PURPOSE:To perform the stable removal of phosphates over a long time, while recovering the power of dephsphorization, by dewatering calcium phosphate- contg. crystal seeds which was brought into contact with phosphate-contg. waste water for the removal of phosphates from it to activate them. CONSTITUTION:Phosphate-contg. water of a pH above 6 is circulated as an upward or downward stream through a stationary bed packed with crystal seeds having a particle size of 9-35 meshes and containing calcium phsphate such as hydroxyl appatite at a speed of SV 1-5hr<-1> to precipitate the crystal of calcium phosphate and to remove phsphates from the water. When the activity of said crystal seeds is deteriorated during the continuation of said treatment, the crystal seeds are activated by dewatering. Said dewatering is generally performed by dewatering the crystal seeds and evaporating a water part. In case of large- sized arrangements, the supply of water is suspended, and the stationary bed is dewatered, backwashed at need and then spontaneously dried for about a week.

Abstract: PURPOSE:To improve rigidity of a cassette and to prevent generation of impulsive sound by devising a paper sheet feeder of a copying machine so that a pressure unit of a middle plate of the cassette is forcibly pushed down in linkage with cassette extraction action. CONSTITUTION:When a cassette 30 loading a sheet S is installed on a cassette installation part 2, the free edge of a pressure lever 17 is turned in the arrow 46a direction by contact of a side cam 43 of the cassette 30 and a pressure boss of the cassette installation part 2, and a driven lever 15 pulled by a pressure spring 21 is turned in the arrow 22a direction. Consequently, a pressure piece 13 is also turned in the same direction and pushes up a free edge 33a of a middle plate 33 of the cassette 30 and pressurizes the top sheet against a feed roller. Subsequently, when the cassette 30 is extracted from the installation part 2, the pressure lever 17 goes down by force of the pressure spring 21 and the pressure plate 11 is forcibly descended.

Title: Individual selective call receiver with display
Inventor: UMETSU SHINJIROU
IPC: H04W84/02
Filed: 1983-07-22
Abstract: PURPOSE:To read distinctly display contents even in case of a variance of environmental temperature by changing the display driving time of a display element of a liquid crystal display device in accordance with the temperature. CONSTITUTION:A radio frequency signal from an antenna 1 is demodulated by a receiving part 2 and is supplied to a decoder 3. The decoder 3 collates the demodulated signal with contents in a call number storage part; and if they coincide with each other, the decoder 3 decodes the next display information signal and supplies display information to a display driving part 8 and supplies a sounding signal for reporting a call to a sounding amplifying part 5. The amplifying part 5 amplifies the sounding signal to drive a speaker 6. When a switch 7 is depressed, the decoder 3 stops the supply of the sounding signal, and the driving part 8 drives a liquid crystal display device 9 to start the display. A driving time setting part 10 sets a time according with a detected temperature on a basis of the signal from a temperature detecting part 11, and the display driving part 8 drives the liquid crystal display device 9 only for this set time.

Title: Copying machine
Inventor: KIDA YUJI
IPC: G03G15/20
Filed: 1988-05-31
Abstract: PURPOSE:To improve copying quality by fixing developer on a recording sheet by means of heating and selecting a relatively lower fixing temperature which exceeds the fusing temperature of developer in a copying machine whose fixing speed is relatively lower. CONSTITUTION:The copying machine 11 is a type that fixes the developer on the recording sheet 28 by heating at a relatively lower fixing speed. In thermal fixing, it fuses the developer on the recording sheet 28 to fix it. The fixing temperature is selected within a range exceeding the fusing temperature of the developer, however its exceeding amount should be small. Even the copying machine that transfers and fixes at a relatively lower speed never imparts an excessive heating value, whereby quality deterioration due to a crinkled sheet never occurs.

Abstract: PROBLEM TO BE SOLVED: To greatly reduce piezo electric field effect, and to obtain a GaN-based semiconductor device with large light-emitting efficiency by performing inclined doping for reducing the concentration of impurities monotonously or in steps to the barrier layer of an MQW active layer. SOLUTION: A buffer layer 2 is deposited onto a substrate 1 for increasing temperature, thus sequentially laminating an AlGaN layer 3, an nAlGaN cladding layer 4, an nGaN light guide layer 5, a multiple quantum well(MQW) active layer 8, and a pGaN contact layer 9. In this case, the concentration of Si that is n-type impurities in the band structure of the MQW active layer 6 and a barrier layer is reduced from 5×1018 cm-3 or the like successively or in steps. Also, doping is made merely at the side of the substrate (an n- cladding side). In either case, it is important that the concentration of the Si at the n-cladding side is high. Doping is made in this manner, thus greatly and effectively canceling a piezo electric field being generated by strain.

When restoring the operating valve 2 to neutral position 2 2  to stop the load 7, since the pipelines 8 and 9 are connected with each other because the operating valve 2 is in the neutral position 2 2 , the whole amount of oil pressure discharged by the pumping action of the oil pressure motor 6 by loading inertia is flowed into the pipeline 8 and the counter-balance valve 3. Thus, the occurrence of cavitation due to the shortage  of oil can be exactly prevented without causing oil shortage on the suction side of  the oil-pressure motor 6.

Abstract: PURPOSE: To keep the setting property of an armature constant in an impact type printer, by supporting a mass member for absorbing the kinetic enerby of the armature by a leaf spring, and providing a buffering member behind the leaf spring.  
     CONSTITUTION: The armature 3 with a wire fixed thereto is repulsed from a paper sheet after the printing, and strikes the mass member 17 to be stopped. The mass member 17 is fixed to one end of the leaf spring member 16 the other end of which is connected to a fitting member 12, and when the mass member 17 is given the kinetic energy of the armature 3, while it is pressing the buffering member 18 snuged in a fitting hole 13 in the fitting member 12, its energy is dissipated, and it is restored to its original position to be incontact with the armature 3. In this case, since the mass member 17 is supported by the leaf spring member 16, even when the buffering member 18 is deformed, the contact state of the mass member 17 and the armature 3 would not be changed. The adjustment of the displacement of the armature 3 is effected by an adjusting screw 15.

Title: Light quantity adjusting device for laser beam printer
Inventor: HIROTA TETSUO
IPC: G03G15/043
Filed: 1987-05-31
Abstract: PURPOSE:To prolong the life of a photosensitive body by making an adjustment continuously while no synchronous detection signal is generated and making the adjustment when a scan is made except on a photosensitive body after the quantity of light where a synchronous detection signal is generated is obtained. CONSTITUTION:While light emitted by a laser diode is too weak to detect by a photosensor and no synchronous detection signal is generated after a power source is turned on, a pulse generating circuit part 11 to which a light quantity adjustment start signal is inputted outputs a pulse signal, which is loaded in a counter 13 while loaded in a timer 12. A count-up signal is inputted from the circuit part 20 of a mode 1 to the counter 13 according to the output from the timer 12 to a time output pulse generating circuit part 19, so that the quantity of the light increases continuously. When the quantity of the emitted light increases to a certain extent, the photosensor detects that and generates synchronous detection signal and a mode 2 is entered. At the same time, write timing is determined by the generation of the synchronous detection signal and the diode is turned off for the light quantity adjustment when its scanning line leaves the photosensitive body. Consequently, the photosensitive body is prevented from deteriorating and its life can be prolonged.
