Title: Process and apparatus for pretreatment of charcoal introduced into coke oven
Inventor: MATSUDAIRA KANJI
IPC: C10B57/10
Filed: 1999-01-07
Abstract: PROBLEM TO BE SOLVED: To provide a pretreatment process for coals to be introduced into a coke oven wherein the coals are more successfully dried and generation of dust at drying is prevented. SOLUTION: Coals are dried to different levels depending on their dusting characteristics. Coals having high dusting characteristics are weakly dried in a dryer 3K2 (drying is stopped at a relatively high moisture content), and coals having low dusting characteristics are firmly dried in a dryer 3K3 (drying is continued until a low moisture-content is attained). Coals having moderate dusting characteristics are moderately dried in a dryer 3K1. By drying each coal to an adequate level, generation of dust is prevented. Furthermore, the moisture content of the introduced coals as a whole is reduced.

Abstract: PURPOSE:To control refrigerating cycle in a small amount of refrigerant, by providing a refrigerating device with a condenser saturation temperature detecting circuit and an evaporator saturation temperature detecting circuit. CONSTITUTION:High-temperature refrigerant gas from a compressor 1 flows into a condenser heat exchanging unit 6 and heat exchange is effected between external heat whereby a portion of the high-temperature gas is liquefied and flows into the liquid reservoir 7 of a condenser.

Accordingly, the refrigerant in the liquid reservoir 7 shows a constant gas and liquid mixing condition in spite of the amount of heat exchange in the heat exchanger 6 whereby the temperature of the liquid reservoir 7 becomes a condenser saturation temperature. The temperature of the liquid reservoir 10 of an evaporator shows an evaporator saturation temperature.

Title: Hair winder for permanent wave treatment
Inventor: MOORIN KIMU HIEYON SOTSUKU
IPC: A45D2/14
Filed: 1994-01-18
Abstract: PURPOSE: To treat only a second growth area of hair by joining a strip of foil to a winding member, and rolling it on the winding member together with hair. CONSTITUTION: A hair winder has a winding member 1 integrally formed with a head whose end is expanded, and one head has a coaxially projecting knob 2, and a rubber band is joined to a notch in an opposite side head so as to be removable from its other end. A flag-shaped strip 5 of foil generally has a length longer than a width so that a sufficiently long hair area is surrounded and is covered with the strip 5 of the foil. Hair to be treated is thinly rolled in an ordinary mode on the strip 5 of liquid impermeable thermoplastic foil, and the hair to be untreated is reliably protected under its foil 5. When reaching second growth of the hair, the strip 5 of a proper length can be simply cut. As a result, when a winding process continues, the hair cannot move any more under the foil 5, and therefore, the pretreated treatment hair can be protected.

Abstract: PURPOSE:To contrive the prevention of disconnection of the lower metal interconnection layer and the improvement of etching efficiency by a method wherein a laminate consisting of a plurality of layers of insulating layers laminated between the upper and lower metal interconnection layers is etched at a time by a reactive ion etching method. CONSTITUTION:An Si nitriding layer 102, a Zr oxide layer (coupler layer) 103, a polyimide layer 104, an Si oxide layer 105 and a P-type resist pattern layer 106 are formed on an Al interconnection layer 101 arranged on an Si substrate 100. First, the layer 105 is etched by a reactive anisotropic ion etching method. Then, an etching is performed on the layer 104 by an isotropic etching method. Hereby, as a protrusion part 105a of the Si oxide layer 105 is protruded in an overhang form. Subsequently, the layer 103 and the layer 102 are etched. In these etchings, as the protrusion 105 is used as a mask and the start of etching to the layer 102 just under the protrusion is delayed, the final etched shape is formed into a two-stage. According to the above method, an etching efficiency is improved because the laminate is etched at a time and also, the disconnection of the Al interconnection layer whose Al interconnection is adhered on the layer 105 is prevented because the layer 105 has no overhang.

Title: Optical switch
Inventor: MAKINO TOSHIHIKO
IPC: G02F1/313
Filed: 1985-01-11
Abstract: PURPOSE:To attain very high speed switching operation without reflection due to the discontinuousness of a connection part by arranging a dielectric substrate on which a microstrip line terminated by a chip resistor is formed close to electrodes of an optical switch and supplying a switching electric signal from a microstrip line. CONSTITUTION:The chip resistor 9 is connected between a center conductor 8 of the microstrip line and an earth conductor 10. If the resistance value of the resistor 9 is selected equally to the characteristic impedance of the microstrip line, the impedance observed from a terminal 13 becomes an impedance value obtained by adding capacity between electrodes 5, 6 to the characteristic impedance of the microstrip line in parallel. When the frequency of the switching electric signal is increased, the mismatching of the impedance is increased because of the capacity between the electrodes 5, 6. However, 3dB band width can be increased up to 5-6GHz and very high speed switching can be attained because the electrode capacity of the switch can be set up to about 1PF.

Filed: 1987-01-10
Abstract: PURPOSE:To prevent the occurrence of cavitation and improve pump efficiency by controlling a pump so as to apply waved driving voltage for making the control of the return motion of a plunger possible to a solenoid driving the plunger of the pump. CONSTITUTION:When a solenoid 2 is turned on, attractive force generated between a fixed core 4 and an armature 3 moves a piston (plunger) 4 downward against a spring 5. Liquid in a pressure chamber 11 is therefore pressurized to be discharged through a delivery valve 13. In this pump, sinusoidal wave driving voltage is applied to the solenoid 2 through a driver 21 on the basis of a sinusoidal wave signal generated by a sinusoidal wave generator 20. Thus the solenoid 2 is turned on with sinusoidal wave current lagging somewhat in its phase to cause the magnetic force of the solenoid 2 to move a piston 4 downward in the case of the increasing current, and on the other hand, its attractive force decreased gradually to slowly return the piston 4 in the case of the decreasing current.
