摘要： PURPOSE:To perform the loading without making a slider contact with a magnetic disk and to prevent the occurrence of dust by performing the loading with a loading means until the device becomes the loading state when the device is under the nonloading state. CONSTITUTION:Loading operation is stopped upon occurrence of such a state that the rotation of the magnetic disk 5 is turned down below a prescribed revolving speed during the loading operation when the rotation of the magnetic disk 5 is stopped or turned down below the prescribed revolving speed after starting the loading operation when the magnetic disk 5 reaches the prescribed revolving speed. Consequently, even when the rotation of the magnetic disk 5 is stopped during the loading operation, such matters as the occurrence of dust and the destruction of data due to adsorption between the slider 3 and the magnetic disk 5 and flawing the magnetic disk 5 by the slider 3, adsorption between the slider and the magnetic disk and crush of the slider and the magnetic disk are eliminated, and hence high reliability of a magnetic disk drive device can be secured.

摘要： PURPOSE:To obtain a bread capable of well being spread in a heating unit by a method wherein more than two stages temperature zones of baking temperature are provided in a control part for use in controlling a heating temperature or a heating time and a first stage temperature zone is applied as one in which ferment reacting with starch in dough is not deactivated. CONSTITUTION:A heating chamber 16 is provided with a temperature sensor 13 for use in detecting a temperature within the heating chamber 16. Another temperature sensor 14 for use in detecting vapor discharged from a heated item 17 is arranged within the heating chamber 16 or on an air passage. A control part 12 may detect a state of the heated item 17 or a temperature state within the heating chamber 16 in response to values from the temperature sensors 13 and 14 and further control heating sources 15a, 15b and 15c. As a heating sequence under the control part 12, a primary baking temperature, a secondary baking temperature Temp 4 and Temp 5b during a baking operation are provided, and as regards Temp 4, it is set to such a value as a ferment alpha-amirase required for spread of dough in the container is activat ed more. With such an arrangement, it is possible to promote a sufficient spread of dough in the container and to make such a bread as one having a superior taste, shape, odor and color or the like.

摘要： PROBLEM TO BE SOLVED: To shorten a cooking time by eliminating a contact of water droplets generated in a heating chamber with a heating element of a heater and allowing a heat from the heater to be easily transferred to the chamber in a heating cooker having the heater at a lower part of the chamber. SOLUTION: A protective wall 9 is disposed obliquely to a horizontal direction between a heating chamber 1 and a lower heater 5. Accordingly, since water droplets generated from the chamber 1 flow down along a slope of the wall 9 and are discharged out of the heater 5, the droplets are not brought into direct contact with a heating element of the heater. The heat of the element can directly heat the chamber 1 without being shielded by the wall 9. Since the heat is not allowed to lead between the chamber 1 and the heater 5, use of a component a high heat resistant type is not required. Thus, the heating cooked having a short cooking time and small using electric energy becomes highly safe and economic.

摘要： PROBLEM TO BE SOLVED: To save energy while enhancing cooking performance by shortening the heating time. SOLUTION: A heating chamber 12 for containing an article to be heated is provided with means comprising a reflecting section 15 and a heater 16. The reflecting sections 15, 21 are formed of Fumed SiO2 having ultrafine porous structure and the heaters 16, 22 are embedded and secured while exposing a part thereof to the surface of the reflecting section 15. Since energy supplied to the heating chamber 12 does not escape easily and heat in the heater sections 14, 20 is reflected inward efficiently, heating time is shortened and cooking performance is enhanced while saving energy.

摘要： PURPOSE:To increase the backup time of a battery and reduce a charging time by providing a judging controller for determining whether it is necessary to hold the data of a semiconductor memory circuit in the time of a backup and a hold judgment control circuit for actuating a backup circuit when required. CONSTITUTION:When backup is conducted, a hold judgment control circuit CPU 8 judges the necessity of the hold of the memories A and B of a semiconductor memory circuit, when unnecessary, the memories A and B are not held and, when necessary, they are held by operating a backup circuit 6. Thus, an electric power is not dissipated for holding data which may be erased to save electric power. Especially, when the memory of a semiconductor circuit is divided into a plurality of areas A and B are every area is made judge and control the necessity, the data can be held with the less electric power. Thus, a backup time can be increased and a charging time can be reduced.

摘要： PURPOSE:To efficiently dry garbage within a short time by a simple structure and to easily take out the garbage by providing a pressure reducing means reducing the pressure of a heating chamber to the heating chamber and providing a grinding means grinding garbage and a drain pipe equipped with a drain valve to the bottom part of the heating chamber. CONSTITUTION:Garbage 3 is ground by the detachable grinding means 5 arranged in the take-out container 13 driven by a drive means 4 such as a motor. A fluid such as water passes through a reverse flow valve 7 from a reverse flow means 6 to be sent in a heating chamber 2 through a water flow pipe 6-1 to flow as shown by an arrow and, therefore, the dust bonded to the heating chamber 2 is excluded to be gathered to the bottom part in the heating chamber 2. The fluid accumulated in the heating chamber 2 is discharged from the take- out container 13 composed of cloth or a net through a discharge valve 8 while the garbage 3 is left in the heating chamber 2. The garbage 3 is heated by the magnetron 11 arranged so as to supply high frequency to the heating chamber 2 under the control due to a control part 12 and, since the b.p. of the garbage is lowered under reduced pressure, the garbage 3 is dried within a short time without being putrefied.

摘要： PURPOSE:To lower the boiling point of water that occupies most part of garbage and efficiently dry the garbage with small power by providing a pressure reducing means for reducing pressure within a heating chamber. CONSTITUTION:A freely opening and closing door body 2 is provided on the upper face of a cylindrical heating chamber 1 and garbage 3 is collected into the heating chamber 1 and then the heating chamber 1 is sealed via ring-shaped packing 4. A rotary blade 9 is provided for preventing unevenness of heating of garbage 3 by microwaves. In order to seal the inside of the heating chamber 1, the rotary blade 9 is driven by a pair of magnets 10,11 and a drive means 12 from outside the heating chamber while not in contact with the magnets 10,11 and the drive means 12 and rotates the garbage 3. Air in the heating chamber 1 is discharged from an exhaust hole 13 provided through one side face of the heating chamber by a pump 14 serving as a pressure reducing means. Thereby a stable drying process is made possible.
