Title: Refrigerator
Inventor: ABE TAKUMI
IPC: F25D17/08
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To reduce an invasion and a leakage of an atmosphere in the case of opening a door by forming a cold air curtain in an opening of a storage chamber by circulating cold air in the storage chamber in the case of opening the door in a refrigerator having the door of the chamber openably closed and the storage chamber cooled. SOLUTION: The refrigerator 1 comprises a heat insulation case 6 of a front surface opening in such a manner that the case 6 is partitioned into a cold storage chamber 11, a deep freezing chamber 13 and a vegetable chamber 12. In this case, at the time of opening a door 14 of the chamber 11, a blower 68 is operated by a controller, and an illumination lamp 59 is lit. Cold air in the chamber 11 is sucked from suction ports 74, guided to the blower 68 through a communicating duct, and diffused to a back surface duct 57. Then, the air is introduced into a ceiling duct 71, fed forward and diffused from air outlets 72 to the opening of the chamber 11. Thus, a cold air curtain is formed over the entire opening of the chamber 11 to prevent an invasion of the atmosphere into the chamber 11 and a leakage of the air from the chember 11.

Title: Solid electrolyte fuel cell
Inventor: HASUDA YOSHIAKI
IPC: H01M8/12
Filed: 1992-09-22
Abstract: PURPOSE:To obtain a solid electrolyte fuel cell which is free of warpage and cracks and excellent in reliability, by conforming the thermal expansion coefficient of a solid electrolyte to that of a fuel electrode. CONSTITUTION:A fuel electrode shall be made of nickel zirconium cermet containing 20 to 30% nickel particulate powder by volume. By this constitution, since the fuel electrode contains less nickel, a fuel cell in which a solid electrolyte well conforms to the thermal expansion coefficient, is materialized. Moreover, since each nickel particle is small in size, the three phase interface of electrode reaction is increased in volume, the fuel cell high in output can thereby be materialized.

Title: Disk driving device
Inventor: TAKASE TSUNEMITSU
IPC: G11B19/20
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To detect the biased center of gravity of a disk. SOLUTION: When a disk is loaded, control is performed such that the disk is rotated at a low speed, for example a double speed (S001 to S003). A focus servo loop for causing the laser diode of an optical pickup to emit light is turned on, the level of an MPP(Main Push Pull) signal supplied from an RF amplifier is measured, and the amount of vibration is recognized based on the level of the MPP signal (S004 to S006). Then, this vibration amount is determined (S007), and if the vibration amount is determined to be equal to a threshold X or higher, a spindle motor is set to be rotated at, for example a speed four times faster (S008). If the vibration amount is determined to be lower than the threshold X in step S007, then control is performed to gradually accelerate the rotational speed of the spindle motor (S009 to S010).  If the current rotational speed of the spindle motor is equal to a speed of 8 times faster or higher in step S009, then the vibration amount is compared with thresholds Z (S011) and Y (S013), a required rotational speed is set (S012), (S014) and (S015).

Title: Program starting method
Inventor: KIMURA HIDEO
IPC: G06F9/46
Filed: 1995-10-02
Abstract: PROBLEM TO BE SOLVED: To satisfactorily and independently deliver parameters between programs before and after the start. SOLUTION: A program PA on the staring side determines a process name PRGB of a program PB on the started side. The started side obtains its own process name, and thereby, the starting side and the started side obtain a common keyword, and a mail box M1 of the same name is used to deliver parameters. Consequently, parameters are not delivered from other programs having different keywords, and parameters are delivered independently for every keyword. When the program on the starting side starts plural programs, it gives process names different for every program to independently deliver parameters.
