Patent MY-177673-A (MY)
Title: Refrigerator
Inventor: ITO YUKI
Filed: 2016-08-17
Abstract: A refrigerator (1) includes: a heat insulation box (90) having a storage space therein, the storage space being partitioned into a plurality of storage compartments (100, 200, 300) by a partition member (50); a low-temperature compartment (13) provided as one of the storage compartments and configured to store a cooling target object at a temperature equal to or lower than a freezing point of the cooling target object without freezing the cooling target object; a cooling device (19) configured to cool the storage space; and a controller (7) configured to control the cooling device (19) to repeatedly perform a first process of decreasing a compartment temperature of the low-temperature compartment (13), to a first temperature lower than the freezing point of the cooling target object, from a second temperature higher than the freezing point in a duration set in advance, and a second process of increasing the compartment temperature from the first temperature to the second temperature and maintaining the second temperature for a duration set in advance. The controller (7) performs control so that a time integral value of a difference between the freezing point and the compartment temperature of the low-temperature compartment (13) while the compartment temperature of the low-temperature compartment (13) is lower than the freezing point balances with a time integral value of the difference between the freezing point and the compartment temperature of the low-temperature compartment (13) while the compartment temperature of the low-temperature compartment (13) is higher than the freezing point.

Title: Apparatus for setting and indicating operating modes of a motor control system (controller)
Inventor: RUZICKA BRUNO ING
IPC: G05B19/10
Filed: 1985-04-16
Granted: 1990-06-11
Abstract: A function key 1 and two selection keys 2, 3 are used in conjunction with a control indication 8 to operate (control) a microprocessor 6 which controls the operating states of a motor control system. The more functional use of the switching and indicating elements allows the space- saving construction of a reliable and quick operating system, with the assistance of parameters for adjustment. An electrical erasable read only memory 12 ensures that the data which have been input are protected when the motor control system is switched off, or in the event of a power failure. The individual control and adjustment programs for the microprocessor 6 are selected by means of parameters. These are indicated in the parameter mode, and are changed step by step by operating the selection keys 2, 3. In the value mode, the function key 1 switches over, and the appropriate parameter value is indicated. This may be a measured value, or may be changed, as an input, using the two selection keys 2, 3. By means of the adjustment and indicating elements and in conjunction with the microprocessor 6 it is not only possible to output a fault message relating to fault parameters, but also to carry out a diagnosis of the memory contents in the microprocessor 6. <IMAGE>

Granted: 2001-12-27
Abstract: There is disclosed a device for the protection of objects or body parts against vibrations, in particular a vibration-damping glove or antivibration glove, including at least one vibration-damping layer. In order to realize such a device, which causes noticeable damping of vibrations even in the low-frequency range of vibrations (31.5 to 200 Hz) and, in addition, remains maneuverable to the largest extent possible, at least one vibration-damping layer, on its surface facing away from the object or body part to be protected, includes indents for decoupling movements in at least one direction in the plane of that surface. The indents, on the one hand, cause the vibrations oriented in the plane of the surface to be deflected into the interior of the layer, thereby enhancing the vibration-damping effect, in particular in the low-frequency range. On the other hand, a high degree of movability of the vibration-damping layer, and hence of the overall device, is ensured by the indents.
