Title: Asynchronous transfer mode switchboard
Inventor: OCHIAI TAMIYA
IPC: H04L12/28
Filed: 1993-10-08
Abstract: PURPOSE:To eliminate the bussy modes between processors and to process a large quantity of data at a high speed by preparing a buffer area of large capacity in a shared memory for communication of data between processors and controlling the buffer area by means of the final read/write address. CONSTITUTION:An asynchronous transfer mode switchboard consists of the processors 101 and 102, a common memory area 103 and an I/O 104. The area 103 includes a buffer area 105 which functions as a buffer that performs communication of data between both processors and a pointer area 106 which stores the 1st and 2nd pointers that show the final write address and the final read address respectively. Thus the area 103 can store a large quantity of communication data through the area 105. Furthermore the area 105 is cyclically used and at the same time the writing operations using both pointers are inhibited to the unwritten areas of the area 105. In such a constitution, the buffer area is effectively used.

IPC: A01D34/63
Filed: 1992-08-31
Abstract: PURPOSE:To accurately detect the fullness of a bag with grass a reaping machine and to simultaneously facilitate handling of a chute and the grass bag. CONSTITUTION:A lid 12 covering a chute 14 is openable and closable around a supporting shaft 34. A light sensor 17 is attached to the side of the lid 12 and emits light beam to the inside of the lid 12. A turning reflecting plate 39 is arranged at the extended line of the light beam. The light beam reflected by the turning reflecting plate 39 is detected by a receptor in the light sensor 17. The light sensor discovers a full grass bag by density of turf drifting in the vicinity of an outlet of the chute at the top of the bag. In the case where a light receiving level at the receptor 17b is <= a threshold value, the light sensor 17 outputs a signal for detecting a screened state of light. A control part not shown in the figure judges a fullness of bag when the signal for detecting a screened state is continued >= a given time and operates an alarm device.

Inventor: WASHITANI TADAHIRO
IPC: G21C19/46
Filed: 1991-10-01
Abstract: PURPOSE:To enable specified product specifications to be attained even if an amount of reducing agent to be added is reduced and the number of distribution stages of a multi-stage extraction device to be reduced by adding the reducing agent to diluted nitric acid in a specific range of a reducing agent ratio and performing distribution temperature in a specific range. CONSTITUTION:A co-decontamination process for extracting U and Pu to an organic phase is carried out by bring a nitric acid solution of a spent fuel into contact with a 30% TBP organic phase, and a distribution process is carried out by bringing the organic phase into contact with a Pu back extraction liquid which consists of a diluted nitric acid for back extraction of Pu to nitric acid water to keep U in the organic phase. In this case, a reducing agent is added to a diluted nitric acid which is a Pu back extraction liquid within a range of 0.02 to 1 in terms of the reducing agent ratio (amount of reducing agent/amount of Pu) with a distribution temperature being 10-30 deg.C. A distribution coefficient ratio of U to Pu can be increased and a large amount of Pu can be back-extracted to a nitric acid water phase in non-reduced state for separation from U, thus enabling an amount of added reducing agent to be reduced drastically. Also, by adding a small amount of reducing agent, Pu which stays within the organic phase can be readily and back-extracted in short distribution steps.

Title: Oil and fat removing method for heating pipe of water feeding heater device
Inventor: OBARA TETSUO
IPC: F28G11/00
Filed: 1987-10-12
Abstract: PURPOSE:To eliminate an alkaline cleaning and reduce the number of steps expenditure by a method wherein atmosphere within a water feeding heater is adjusted during an entire annealing operation to get an effect of annealing and then oil and fat substances adhered to the heating pipe are burned lost. CONSTITUTION:An order of assembly of a water feeding heater is set such that at first a short barrel 2 and a pipe plate 5 are welded, thereafter heating pipes 3 are inserted into holes of the pipe plate 5 and lastly a water chamber 4 is welded and fixed to the pipe plate 5. The heating pipe 3 is kept coated with anti-corrosion agent containing oil and fat substances. Each of the abutting portions of the water feeding heater is connected by a welding operation, so that an annealing is carried out for the device after completion of its assembly. As sealing gas, mixture gas containing oxygen of 1.1% and nitrogen of 98.9% is used. This is applied in order to restrict a concentration of oxygen of lower limit value required for making a complete diminishing of oil and fat substances due to the fact that a burn lost of the oil and fat substance adhered to the surface of the heating pipe 3 is dependent upon a concentration of oxygen in the igniting atmosphere. With this arrangement, the oil and fat substances are completely burned lost and a bad influence of the combustion against the heating pipe 3 can be prevented.

Filed: 1991-09-06
Abstract: PURPOSE:To obtain a thin film inductor which has a high inductance and Q and can be used in a wide frequency band by successively forming coil conductor films and an insulating film on a magnetic substrate. CONSTITUTION:Coil conductor films 5 and an insulating film 4 are successively formed on a magnetic substrate 2. For example, after a Cu film having a thickness of 5mum is formed on the surface of a magnetic substrate 2 composed of an Ni-Zn ferrite by a sputtering method, the coil conductor films 5 are formed by patterning the Cu film. After forming the films 5, a photosensitive resin is applied to the surface of the substrate 2 including the films 5 and, after unnecessary parts are removed by exposure and development, the insulating film 4 having a thickness of 5mum is formed by heating and hardening the resin. Then, after a 'Permalloy(R)' film is formed by a sputtering method, a magnetic film 3 having a thickness of 3mum is formed by patterning the 'Permalloy(R)' film. Thereafter, a protective film 6 is formed by forming an Al2O3 film having a thickness of 3mum by a sputtering method after masking the surface of a section for terminals.

Title: Waterproof type pushbutton
Inventor: SASAKI SHIGEMITSU
IPC: G04B3/04
Filed: 1993-09-17
Abstract: PURPOSE:To reduce a member cost and to largely decrease an assembling man-hour by integrally molding a pushbutton with a Q ring and a snap ring via elastic resin. CONSTITUTION:A pushbutton is integrally molded with elastic resin in shape for satisfying functions of a Q ring and a snap ring. A size of an outer diameter of a protrusion is formed slightly larger than a diameter of a hole of a side 5 of a watch, and mounted by press injecting at the time of assembling. Since the diameter of the protrusion of the pushbutton is larger than that of the hole when assembled with the side 5, it is press injected at the time of assembling. When mounting is completely it is fanned of an elastic member, and hence it tends to return to its original shape, and set in a pressure welding state with the hole. Thus, it can be formed in a waterproof structure. Since the shape of the protrusion is square in a reverse direction to its inserting direction, it is prevented from being removed.

Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of a slightly chargeable toner even in the case of a reduced particle diameter, to also suppress the occurrence of an excessively chargeable toner and to ensure stable chargeability by specifying BET specific surface are and particle size distribution. SOLUTION: This toner has >=5m<2> /g BET specific surface area. The upper limit is <=150m<2> /g from the viewpoint of technique and it is preferably <=100m<2> /g. The especially pref.
