Title: Electronic equipment, back light control method, and recording medium
Inventor: FUKUCHI YASUNOBU
IPC: G06F15/02
Filed: 1997-10-23
Abstract: PROBLEM TO BE SOLVED: To make porolongable the time of driving by a battery while limiting the supply of power to the back light of a liquid crystal display(LCD). SOLUTION: Concerning the electronic equipment having the LCD provided with a back light 24a, a CPU discriminates whether input operation is turned into unnecessary processing waiting state during the execution of an application or not based on the power saving mechanism of an operating system and when it is discriminated that the input operation is turned into the processing waiting state, a low luminance signal is reported to an inverter circuit 18. The inverter circuit 18, which receives the low luminance signal, lowers the value of a current to be supplied to the back light 24 through a back light control circuit 18a and attains power saving by turning the back light 24a into luminance.

Title: Megative pressure slider
Inventor: OKADA HIROSHI
IPC: G11B21/21
Filed: 1994-11-25
Abstract: PURPOSE: To obtain a negative pressure slider not damaging a flexible magnetic disc by forming the negative pressure slider of plastic which attracts the magnetic disc by a negative pressure generated by the rotation of the disc and setting the hardness of a projecting face part at a predetermined value. CONSTITUTION: This slider comprises a negative pressure slider 1, a magnetic head 2 and a magnetic disc 3. The disc rotates in a direction of an arrow, and a step part 1A of the negative pressure slider 1 is arranged at the side from which the disc enters, thereby to generate a negative pressure. The magnetic disc 3 is attracted to the negative pressure slider 1, approaching a projecting face part 1B of the negative pressure slider 1 via a considerably thin air film to be partially in touch with the projecting face part 1B depending on the surface state of the part 1B. The Rockwell hardness M of the projecting face part 1B is set to be 50 or larger. The negative pressure is generated by the air flow due to the rotation of the disc 3 and required to keep a gap in a certain range.  Since the disc is flexible, the gap should be kept within the range before the rotation of the disc for any disc. The negative pressure slider is moldable of plastic, and therefore less irregular in shape and mass-producible.

Title: Blade for electric fan
Inventor: SHIBATA KUNIHIRO
IPC: F04D29/38
Filed: 1994-10-20
Abstract: PURPOSE: To realize blast approximately similar to nature having a change in a wider range by a method wherein a flap plate is arranged radially from a vane support shaft cylinder at each blade of an electric fan. CONSTITUTION: The operation button switch of an electric fan is turned ON and the blade 1 of the electric fan is rotated. A proper rotation speed is selected by a speed switching device and when oscillation is needed, the switch of an oscillation mechanism is turned ON for use. Air flow generated through rotation of the blades 1 of the electric fan is collided with a flap plate 2 and flapped. This operation causes the advance of air flow as the air flow is widely rotated in the rotation direction of the blades 1. Simultaneously, the air flow is fed from a center to the outside. Thus, the air flow generated through rotation of the blades 1 is fed as it is spread in such a state to rotate in the rotation direction of the blade 1 and the air flow having a change is fed to a further wider range.

Filed: 1989-11-10
Abstract: PURPOSE:To make the lens compact by providing flat lenses which are long in the length direction if a panoramic picture plane flatter than the standard picture plane of a film viewed in the direction of the optical axis. CONSTITUTION:The flat lenses 2a, 2b, 2d, and 2e which are long in the length direction X of the panoramic photographic picture plane PF viewed in the direction of the optical axis 0 are provided to the photographic lens for the panoramic camera. Therefore, even when the maximum size of each of the lens, provided to the photographic lens for the panoramic camera, in the lengthwise direction X is nearly equal to the maximum diameter of a necessary circular lens, an unnecessary optical path part corresponding to a part which need not be exposed can be omitted. The sizes Y of the flat lenses 2a, 2b, 2d, and 23 in the direction crossing the lengthwise direction X orthogonally are made much less than the size of the conventional circular lens in the direction Y crossing the lengthwise direction X orthogonally. Consequently, the periphery of the photographic lens for the panoramic camera can be made compact by reducing the lens capacity.
