Title: Copying machine
Inventor: KINOSADA AKIRA
IPC: G03G15/00
Filed: 1985-05-01
Abstract: PURPOSE:To set automatically the most suitable reference value to a developing device by providing a toner replenishment controlling circuit for outputting a toner replenishing signal in accordance with a comparison of an output value of a toner concn. detector, and a reference value which has been stored in a reference value memory. CONSTITUTION:When a developing device 10 containing a toner of a reference concn. and a carrier is installed, in a state that a main switch 26 of a copying machine body 20' has been turned on, as soon as it is installed, a magnetic brush means 11 is conducted electrically and operated, and becomes a stationary state after a prescribed time. On the other hand, as soon as the developing device 10 is installed, a differentiating circuit 27 outputs a differential pulse, and it is inputted to a delaying circuit 28, therefore, after a prescribed time, the delaying circuit 28 outputs a memory command pulse, and a reference value memory 22' stores an output value of an A/D converter 21 of that time. A comparison controlling circuit 29 compares an output value of a toner concn. detector 13, which has been read through the A/D converter 21, and a stored reference value, and based on a result of its comparison, a toner replenishing signal is outputted. In this way, a correct density is set automatically as a reference value in the reference value memory.

Abstract: PROBLEM TO BE SOLVED: To provide a liquid sealing vibration control device which has a simpler configuration, can be manufactured easily, is compact, and shows good vibration control characteristics in a wide region. SOLUTION: A main liquid chamber A formed in a rubber elastic body 1 and an auxiliary liquid chamber B formed in a rubber film 3 are partitioned by a partition wall 2 to communicate them by a first restriction flow passage S1. The partition wall 2 is hollow, a third liquid chamber D is formed in an upper part of an elastic body film 22, a negative pressure chamber C is formed in a lower part thereof, and the third liquid chamber D is communicated with the main liquid chamber A through a second restriction flow passage S2. The elastic body film 22 has a projection part 22b on a lower face at the center and fixes a rising wall 22c at outer periphery on an annular projection part 21f provided on opposing partition wall 2 faces. When negative pressure is introduced into the negative pressure chamber C, the elastic body film 22 is absorbed downward, but a small space 6 is left due to the projection parts 22b, 21f. Therefore, the elastic body film 22 is minutely displaced to absorb the vibration of indistinct sound.

Title: Control of chiller unit
Inventor: POORU JIEI DAFU
IPC: G05D23/19
Filed: 1994-05-09
Abstract: PURPOSE: To prevent chiller units from excessively operating by varying the number of operating compressors in the chiller units and limits imposed on the amount of compression required for the chiller units. CONSTITUTION: When the number of operating chiller units is more than one, the temperature of a coolant is read from a supply side sensor and a return side sensor and parameters are calculated. Thereafter, it is calculated whether or not the chiller units responded to the variation of the chiller performance. When a change in the system is suspended, the temperature of the return coolant is made lower than the set temperature. When the temperature of the return coolant becomes lower than the set temperature, each parameter is set. When there is a change in the system, chiller units in which compressors should be increased or decreased in number are selected, and the variable performance ratio is calculated. Then, when the variation is determined, the limits required to the selected chiller units are varied.

Abstract: PURPOSE:To contrive enhancement of durability of a heat generating element, by a construction wherein a part or the entire part of the heat generating element, which has a specified thickness and functions to rapidly heat an ink to form a bubble, makes direct contact With the ink. CONSTITUTION:A part or the entire part of a heat generating element 7 makes direct contact with an ink. With the element 7 rapidly heated, the ink in the vicinity of the element 7 is rapidly heated, and is rapidly evaporated to form a bubble 11, which is expanded. When the heating of the element 7 is finished, the ink is cooled, the bubble 11 is contracted to disappear, and an ink droplet is ejected. The thickness (d) of the element 7 must satisfy the condition of formula I, wherein lambda is the thermal conductivity of the element 7, DELTAt is the width of a pulse applied to the element, rho is the density of the element, and c is the specific heat of the element. If the thickness of the element 7 does not satisfy the condition of formula I, the element 7 has a great temperature gradient, leading to breakage, and therefore has a short useful life.

Abstract: PURPOSE:To eliminate the transmission loss occuring in the compressive strain to be generated in the stage for forming a reinforced optical fiber and to improve reliability in product administration by providing tensile strain to the optical fiber strands in a reinforcing covering layer. CONSTITUTION:Tensile strain in about, for example, 0.01-0.10% range is provided to the optical fiber strands 1 in a reinforcing coating layer 2 consisting of plural reinforcing fiber materials 5 and a thermally cured thermosetting resin 6 impregnated therein and cured. If the tensile strain is provided to the strands 1 in the above-mentioned way, the generation of compressive stress to the strands 1 owing to the shrinkage of the layer 2 having a high Young's modulus occuring in a temp. change, external force, etc. is obviated and the problem of microbending is eventually eliminated.

Abstract: PURPOSE: To enable to repeat the same cooking a plurality of times by a method wherein cooking control data are cleared only when the predetermined instruction or new cooking control data are inputted in a cooker such as microwave range or the like.  
     CONSTITUTION: The cooking control data are stored by operating a function key part 1 and a numerical key part 2 in a random-access memory 7. When a cooking starting key part 4 is pressed, A Triac 12 is operated, under the control of a starting control part 9, by an output control part 11 in accordance with the stored data. Because, even after the completion of the above-mentioned cooking, the control data is held within the random-access memory 7, the same cooking mode can be repeated only by pressing the starting key part 4 again. Yet, when the function key part 1 or a clear key part 3 is pressed for the input of next cooking data, the former cooking data are cleared.
