Title: Method for reproducing optical disk and optical pickup up
Inventor: ICHIURA SHUICHI
IPC: G11B7/005
Filed: 1994-03-18
Abstract: PURPOSE:To reproduce a high-density recording format disk while assuring interchangeability with a disk of a standard recording format without drastically shortening a wavelength by reproducing an optical disk by using a short- wavelength laser beam condensed in a required direction. CONSTITUTION:The short-wavelength coherent laser beam of the wavelength 610 to 665nm via a semiconductor laser 1 is partly shielded by a light shielding plate 3 and the optical disk D is irradiated with this laser beam. The reflected laser beam is received by a photodetector 8 and the recording information of the disk D is reproduced. The main lobe component M and side lobe components Sa, Sb of ultra-resolution development forming the pits of the shorter sizes than the sizes of the standard format are so condensed as to head a tangent direction by using the partly shielded laser beam. As a result, the disk of the high-density recording format is reproduced by utilizing the ultra- resolution development while the interchangeability with the standard recording format is assured without drastically shortening the wavelength.

Abstract: PURPOSE:To hold a copy mode as it is when an operator leaves the periphery of the operation part of a copying machine in the middle of copying operation by detecting whether an operator is present or not and detecting the end of copying operation, and then changing copy modes on the basis of the AND condition between both detection signals. CONSTITUTION:The operator on an operator detecting means 5 placed on a floor surface 6 nearby the operation part 2 of the copying machine 1 inputs and sets a desired copy mode by operating the operation part, and performs copying operation. The operator opens a pressure plate 3 after the copying operation to remove the copy original, takes copies 9 out of a paper discharge tray 8, and leaves the position on the operator detecting means 5. At this time, the end signal of the copy mode set by the operator is generated and a signal for detecting the operator leaving the copying machine is also generated by the operator detecting means 5. This end signal is obtained by comparing the counted value of the detection signal of an optical lighting system detecting means 8 or copying paper conveyance detecting means 19 with the reserved quantity of copies. The copying machine is switched to the standard mode with the detection signal indicating that the operator leaves the copying machine.

Abstract: PURPOSE:To make it possible to shorten the time of additional burning to a great extent and automatically lower the temperature of the hot water in a bath tub by adding hot water even if the temperature of the residual hot water in the bath tub is high by controlling the combustion of a burner for the supply hot water in a supply hot water circuit according to the hot water temperature in a bath tub and adjusting the temperature of the supply hot water. CONSTITUTION:If, during a bath tub 1 is being filled or replenished with water, the water level in the bath tub 1 is over a certain level, the water in the bath tub 1 is circulated into an additional burning circuit 4 with a certain interval of time. During this water circulation the hot water temperature is detected by a hot water temperature sensor 6 provided in the additional burning circuit 4 and a sensed temperature is compared with a set temperature for the finish of water heating. If a detected temperature is lower than the set temperature by a set temperature, the temperature of the hot water from a supply hot water circuit 2 is raised through control means 8, and when a detected temperature is higher than the set temperature for the finish of water heating, the temperature of the supply hot water is lowered. When the amount of hot water reached a specified amount and a water level sensor 5 is activated, a circulation pump 7 is started, and the temperature of the hot water and the set temperature are compared. If the hot water temperature is lower, a burner 9 for additional burning is activated. If the hot water temperature is equal or higher than the set temperature, the burner 9 for additional burning and the circulation pump 7 stop.
