Abstract: In a solenoid, a coil is energized in a state where movement of a plunger toward the inside of a yoke is stopped. Accordingly, when the coil is energized, it suffice that movement of the plunger toward the outside of the yoke is inhibited by a magnetic force, and it is not necessary to move the plunger into the yoke by the magnetic force. Therefore, it is not necessary that a force moving the plunger toward the inside of the yoke is increased by a conventional core. Accordingly, the conventional core is not assembled in a frame, so that number of components can be decreased so as to reduce the cost.

The polyamide acid solution includes a polyamide acid obtained by polymerization reaction of 3,4,3',4'-biphenyltetracarboxylic dianhydride and p-phenylenediamine in a mixture of a polar organic solvent and a small amount of an imidization agent selected from imidazole, a substituted imidazole, benzimidazole, a substituted benzimidazole, isoquinoline, and a substituted pyridine.

Abstract: A single chip microprocessor 1 includes a CPU 2 and a sub-processor 5 for software implementation of peripheral functions of the microprocessor 1. Sub-processor 5 includes electrically writable internal storage devices microprogram memory unit 13 and sequence control memory unit 62 for storing the software. Peripheral functions are defined and/or modified by writing software into the memory units 13 and 62. Accordingly, the time it takes to define and/or modify the peripheral functions is the time it takes to program the memory units 13 and 62. The sub-processor 5 also includes an execution unit 16 for executing a plurality of tasks and an address control circuit 14 for providing addresses to the microprogram memory unit 13. Additionally, the microprogram memory unit 13 provides microinstructions to the execution unit 16. The sequence control memory unit 62 is part of the address control circuit 14 which also includes a plurality of address registers MAR0 to MAR11.

Abstract: A method for mechanically removing roots from harvested cormatose plant bodies using a special root removing arrangement comprises supplying the harvested cormatose plant body (3) in between two parallel spaced horizontal rollers (1,2) while they are rotating in opposite directions relative to each other so that their peripheral or opposing adjacent inner sides are moving upwards, or in the same rotational direction so that one of these peripheral surfaces on opposing adjacent inner sides is moving upwards, in order that the plant bodies roll on the rollers and become balanced and oriented substantially axially of the rollers, changing the rotational mode of the rollers into a counter rotation mode so that their peripheral surfaces on the opposing inner sides are moving downwards, drawing the beard-like roots (4) of each plant body (3) into the gap between the rollers, forcing each plant body away from the rollers by a plant body thrusting mechanism (5,6,7) to cause the roots to be plucked from the plant body

Abstract: A coffee maker of the centrifugal brewing type includes a brewing case for containing milled coffee beans, the brewing case having a filter provided at the outer periphery thereof for the coffee brewing, a hot water feed mechanism for feeding hot water to the brewing case, an electric motor for rotating the brewing case so that a centrifugal force is applied to the hot water fed into the brewing case, thereby causing the hot water to pass through the milled coffee beans and then, through the filter, and control circuitry for controlling the hot water feed mechanism and the motor so that the motor is driven to rotate the brewing case after the hot water feed is initiated from the hot water feed mechanism to the brewing case.

Abstract: A method for cooking food materials of varying volume in a cooking apparatus or measuring the volume of the cooking material. The method for measuring includes the steps of heating a quantity of food material to a prescribed set temperature in the cooking apparatus, stopping the heating for a first predetermined period for radiating heat from the food material, applying heat to the food material for a second prescribed period, detecting the actual temperature of the food material, measuring a period elapsed until the detecting, and computing a value corresponding to the thermal capacity of the material in the cooking apparatus from the detected temperature and the elapsed time. The method for cooking further includes the step of starting a cooking operation to the food material in the cooking apparatus at a time corresponding to the computed value.

Abstract: A process for the preparation of a diazocyano acid, which comprises reacting a keto-acid or its sodium salt with a cyanogen compound such as sodium cyanide or hydrogen cyanide and a hydrazine in water to form a concentrated aqueous solution of a hydrazo compound, adding acetone and/water to the concentrated aqueous solution to form a solution of the hydrazo compounds, adding chlorine gas to the solution to oxidize the hydrazo compound and form a diazocyano acid, adding acetone to the obtained reaction mixture during or after the oxidation if necessary, and separating and recovering the supernatant layer of the acetone-water solution containing the diazocyano acid from the mixture.

Abstract: A rice cooker has a body provided with an upper opening. A lid for opening and closing the upper opening is swingably supported on the body by a hinge mechanism. The lid has a grip portion extending, like a bridge, along the upper surface of the lid from that portion thereof which is adjacent to the hinge mechanism to that portion thereof which is opposite to the hinge mechanism. The lid is locked at a closed position by a lock mechanism. A tension coil spring is arranged along the grip portion to urge the lid in the direction of opening the lid. Thus, when the lock mechanism is released, the lid is automatically opened by the urging force of the tension coil spring.
