Title: Treatment of silver halide color photographic material
Inventor: ISHIKAWA MASAO
IPC: G03C7/42
Filed: 1984-05-15
Abstract: PURPOSE:To eliminate requirement for washing water completely and to reduce energy cost and load for pollution treatment by incorporating at least one non- diffusible coupler capable of forming a migratory dye by the reaction with an oxidized body of a color developing agent, in a photosensitive material. CONSTITUTION:A treating soln. having fixing capacity is desired to contain a thiosulfate, and the concn. of the thiosulfate in the final tank of a stabilizing vessel is preferred to be 2X10<-5>-4.0X10<-3>mol. Specifically, 2X10<-5>-4.0X 10<-3>mol, more pref. 1.0X10<-4>-3.0X10<-3>mol thiosulfate should be incorporated for the treatment of a positive photosensitive material (color photographic paper). For a negative photographic material (color film for taking), 2X10<-5>-1X 10<-3>mol, more pref. 4.0X10<-5>-8X10<-4>mol concn., is recommended. The thiosulfate in the final tank of the stabilizing vessel may be supplemented by one supply or by divided supply. When thiosulfate is used as a complexing agent for soluble silver in the fixing soln. or a bleach-fix soln., the treatment may be accomplished by only adjusting the thiosulfate in the fixing or bleach-fix soln. accompanied by the photosensitive material. The latter method is more preferred.

Filed: 1980-07-15
Abstract: PURPOSE:To reduce the number of steps of manufacturing a semiconductor device and to save the material cost of the device by forming Darlington connection transistors and speedup diode on semiconductor chip.

Title: Controller for industrial robot
Inventor: KIYOHARA YUUJI
IPC: G05B19/18
Filed: 1981-06-19
Abstract: PURPOSE:To immediately stop the operation if a command pulse is not completely transmitted to a servocontrol section, by transmitting a command signal from an operation section to a servocontrol section with the monitoring at any time. CONSTITUTION:If an output of a flip-flop circuit 3 is not received at a servocontrol section 4, a reception signal from the section 4 is not returned to the circuit 3, and an output at a terminal Q of the circuit 3 keeps H level even at the next transmission of output pulse of an operation section 2. Thus, when the time of a timer circuit 71 of a discrimination circuit 7 is set a little shorter than a pulse interval, the output of an AND circuit 72 goes to H level at the end of this time set to set a flip-flop circuit 73 constituting a holding circuit 73 and an alarm of failure. The sections 2 and 4 receives this failure alarm signal and stop the operation.

Title: Thermosyphon type heat exchanger
Inventor: NITANDA YOSHINORI
IPC: F28D15/00
Filed: 1980-07-11
Abstract: PURPOSE: To prevent gas-to-gas leakage and improve performance recoverability and thermal efficiency by making the lower half of an enclosed vacuum type heat exchanger a heating evaporator vessel of a liquid heating medium, and the upper  half a cooling condensor vessel of the heating medium and preparing lateral fluid  passage holes to both vessels.  
     CONSTITUTION: A liquid heating medium 6 is heated by passing hot gas through hot liquid passage holes 2 of a heating evaporator vessel 3. Thereby, the medium 6 evaporates and moves to a cooling condensor vessel 5. On the other hand, a cold gas is being introduced through cold liquid passage holes 4 of the cooling condensor 5. Therefore, the cold gas is heated by heat exchanging between heating medium vapor and returned to the heating evaporator vessel 3 by gravity. Said structure has no component to cause any leakage between gases, allowing simple gas extraction and filling-in of heating medium, easy recovery of performance, to result in said efficient heat exchanger.

Title: Manufacture of brake calliper
Inventor: KUDO MASAAKI
IPC: F16D65/02
Filed: 1992-04-16
Abstract: PURPOSE:To provide the method for manufacturing brake calliper which can miniaturize the size and lighten the weight of calliper, and improve the freedom of the design system inside a wheel, which is excellent in responsiveness, and whose working cost is reduced. CONSTITUTION:A metallic tube 2 forming a hydraulic pressure supplying hole is arranged in a mold, and the casting is executed so as to cast inserting this tube. As the metallic tube 2, the material of an Al material, a Ni plated Al material, a SUS 304 material, and a Ni plated SUS 304 material, etc., can be suitably utilized. A high pressure solidification casting method for solidifying under a high pressure is utilized for casting. Accordingly, since the hydraulic pressure supplying hole can be formed to a gently curved line or a straight line shape, in comparison with the hydraulic supplying hole of zigzag shape, the calliper can be miniaturized in size and lightened in weight, the flow resistance of the oil inside the hydraulic pressure supplying hole is small, the transmitting speed of the hydraulic pressure is increased, and the responsiveness of the braking operation is improved.

Title: Magnetic disk device
Inventor: ASADA HIDEO
IPC: G11B5/09
Filed: 1988-04-19
Abstract: PURPOSE:To correctly generate an address mark detection signal by providing two level detector whose detection levels are different and two adding- subtracting counters, comparing the count values of the two adding-subtracting counters and generating the address mark detection signal. CONSTITUTION:The title device has two level detectors 2 and 3 whose detection levels are different and two adding-subtracting counters 7 and 8. The one adding-subtracting counter of the two adding-subtracting counters 7 and 8 subtracts when the output signal of the one level detector 2 of the two level detectors 2 and 3 exists in the period of a clock signal and adds when it does not exists and the other counter 8 adds and subtracts in the same way to the output signal of the other level detector 3. The count values counted by the two adding-subtracting counters 7 and 8 are compared and the address mark detection signal is generated. Thus, even when signal distortion caused by the defect of a medium, etc., is generated in a read signal, it is not mistaken for an address mark and the address mark detection signal can be correctly generated.

Title: Melt-extrudable thermoplastic synthetic material capable of surface segregation
Inventor: RONARUDO ESU NOORU
IPC: C08K5/5419
Filed: 1989-04-14
Abstract: A surface-segregatable, melt-extrudable thermoplastic composition suitable for processing by melt extrusion to form a fiber or film having a differential, increasing concentration of an additive from the center of the fiber or film to the surface thereof, which differential, increasing concentration imparts to the surface of the fiber or film at least one desired characteristic which otherwise would not be present, which composition includes at least one thermoplastic polymer and at least one defined additive. During formation of the fiber or film, the additive rapidly segregates in a controllable manner toward the newly-formed surface of the fiber or film, thereby resulting in a controllable differential concentration of the polymeric material, which concentration increases with increasing distance from the center of the fiber or film to its surface. The thermoplastic composition is useful in the preparation of fibers or films which have at least one surface characteristic which is different from that of the polymer component of the thermoplastic composition. Methods for preparing the fibers or films and for stabilizing the thermoplastic compositions under certain conditions also are disclosed. The thermoplastic composition is particularly useful in the formation of nonwoven webs which are used in the construction of such disposable absorbent products as diapers, feminine care products, incontinence products, and the like. <IMAGE>
