Filed: 1990-02-16
Abstract: PURPOSE:To prevent rice from being poorly cooked as rice gruel by a method wherein rice cooking is prevented from being started even if start-up action is carried out when rice in a rice storage becomes low in amount. CONSTITUTION:A control circuit 12 controls a rice cooking means 1, a rice storage means 4, a rice washing means 6, a rice transfer means 7, a water supply means 9 and others, and executes all the steps from rice washing to rice cooking automatically. A first rice absence detector 13 is installed in the rice storage 4, and outputs a signal to the control circuit 12 when it detects the residual amount of rice larger than the maximum cooking amount for a time. A second rice absence detector 14 detects a measurable minimum amount of rice less than the maximum cooking amount and outputs a signal to the control circuit 12. When the first rice absence detector 13 comes into action, an indication which suggests a need of rice supply is indicated on an indicator 15. When the second rice absence detector 14 comes into action at the start-up time, a buzzer alarm 16 sounds to inform that start-up is prevented because absence of rice is detected.

IPC: F23J3/00
Filed: 1984-02-27
Abstract: PURPOSE:To prevent excessively large energy loss from occurring and eliminate the damage of a heat accumulating body by a structure wherein the more outward soot blower injection nozzles locate the larger the diameter of the nozzles is set or the more inward said nozzles locate the smaller said diameter is set and the more outward the nozzles locate the shorter the distance between the nozzles and the heat accumulating body is set or the more inward said nozzles locate the longer said distance is set. CONSTITUTION:The longer the radii R1-R8, on each of which nozzles lie, from an axis 7 becomes, the larger the diameter of the nozzles among the nozzles 111-118 is set and at the same time the longer said radii R1-R8, on each of which nozzles lie, from the axis 7 becomes, the shorter the distance between the nozzle 11 and a heat accumulating body 5 is set, resulting in making the work-done of each nozzle 11 with respect to the unit surface area of the heat accumulating body 5 constant. As a blower 9, a tapered tube, the diameter of which increases gradually towards outward, is employed. Consequently, no waste of soot blower work-done due to the result that the work-done at inward portion is larger than that at outward portion occurs and furthermore no damage of the heat accumulating body develops.

Abstract: PURPOSE:To make quick recovery possible by reserving a recovery area in an external file where a trouble occurs if the unrecoverable medium trouble occurs when the file is updated and storing update result data in this area. CONSTITUTION:If failure in file update due to the medium trouble of a file 12-1 in an external file device 2 is detected when the file is updated, a file processing program 6 reserves the recovery area on the storage area of the device 2. That is, a file label (R) is generated, and the program 6 causes an effective flag of a file label (1) to indicate that the file space designated by the label (1) is ineffective, and the entry address of the label (R) in a volume control table 11 is set and is written in the device 2. The program 6 writes contents of a work area 7, where update result data of the file 12-1 is held, on a file (R) 13 designated by the label (R) of the device 2. Thus, the trouble is recovered quickly without complication procedures.

Abstract: PURPOSE:To obtain a dielectric having a high dielectric constant by incorporating an ionic organic compound into an organic high molecular compound. CONSTITUTION:An ionic organic compound is incorporated as an auxiliary material into such a dielectric that is mainly composed of an organic high molecular compound. As the ionic organic compound, quadri-grade ammonium salt or the like is used. In the process of preparing the dielectric, first of all, an organic high molecular material is dissolved in a suitable organic solvent, and then, an ionic organic component such as quaternary ammonium salt is incorporated into the resultant solution. Next, the deposition of the resultant incorporated solution on an electrode plate results in the formation of an organic high molecular thin film.

Title: Teaching method for laser robot
Inventor: KOSAKA TETSUYA
IPC: B23K26/00
Filed: 1995-02-03
Abstract: PURPOSE: To enable exact teaching in a short period when preparing a working program by preparing data concerning a position away from a working point just for a distance corresponding to a desired working gap along a laser beam for aim. CONSTITUTION: Concerning a coordinate system having an attitude related with a machining object work plane, a user coordinate system is set along a work plane so that a plane ordinarily spread between an XA axis and a YA axis can be matched with the work plane. The laser beam for aim is emitted from a laser tool and a working point position P1' is selected by utilizing jog feeding. The distance between the work plane and the laser tool is suitably selected so that the point irradiated with the laser beam 3 for aim can be easily visually confirmed. Based on the equation of a straight line connecting a tool top end point position P1 and the P1' at such a time, data expressing the position of Pd away from the position P1' just for a distance (d) in the direction of P1 are calculated by the software processing of a robot controller.  Thus, the working point can be designated by irradiating that point with the laser beam for aim from the position having a margin.
