Title: Optical lens, and optical pickup and optical disk device using the same
Inventor: YAMADA TAKATOSHI
IPC: G11B7/1374
Filed: 1998-07-09
Abstract: PROBLEM TO BE SOLVED: To preclude luminous flux of the outside of an optical effective surface, without impairing an optical performance by allowing a projection shaped spherical surface whose surface is rotationally symmetric to be a curved surface having no difference in level as to its radial direction and to have places, where differential coefficients are discontinuous at prescribed radial positions. SOLUTION: An objective lens 24 converges a light beam from a beam splitter on a desired tack on the signal recording surface of an optical disk, which is rotationally driven. Here, the lens 24 is movably supported in biaxial directions, that is, in the focus direction and the tracking direction. Relating to the objective lens 24, the surface 24a of a light source side is a projection shaped spherical surface, whose surface is rotationally symmetric and the surface is given by a function concerning distances (radii) from its optical axis. In this function, differential coefficients are continuous in a domain and coefficients become discontinuous at prescribed positions y0 in the radial direction.  Moreover, since these positions y0 are in the domain and rays of light passing here become marginal rays, these positions are determined, so that the numerical aperture of the lens becomes a prescribed value (necessary numerical aperture).

IPC: B60P3/10
Filed: 1996-07-24
Abstract: PROBLEM TO BE SOLVED: To facilitate the transfer of a small ship by stretching a wire applied on a pulley which can reciprocate from the land over a water surface, lowering a ship transfering device into the water by loosening the wire, and raising the ship transfering device above the sea by applying tensile force to the wire. SOLUTION: When a ship 12 is lowered on the sea water, a wire 112 is fixed in a condition in which the ship 12 is loaded on a ship transfering device 100. Next, a signal is sent to a transmitter and receiver 118 from a transmitter on the ship 12 to drive a drive means, and the wire 112 is moved in substantially horizontal direction due to the rotation of a drive vehicle 110. Consequently, the ship transfering device 100 is moved toward the sea through the wire 112 and is moved above the sea water as it is. Then, a signal is sent to the transmitter and receiver 118 from the transmitter on the ship 12 to drive a cylinder 116 at low speed so that a pulley 114 is moved at low speed and the wire 112 is loosened gradually. Consequently, the ship transfering device 100 is sunk into the sea water gradually due to its self-weight so that the ship 12 floats on the sea water due to buoyancy.

Title: Drum type washing and drying machine
Inventor: AKAHA TATSUO
IPC: D06F25/00
Filed: 1989-07-26
Abstract: PURPOSE:To change the ventilating path of laundry and to finish drying without nonuniformity by providing a means to oscillate an oscillating disk when the laundry is dried, a detected temperature is saturated and afterwards, the hourly change rate of the detected temperature is enlarged rather than a prescribed positive value, and to stop the oscillating disk when the change rate is made smaller than a prescribed negative value. CONSTITUTION:When a rotary drum 12 is set in the initial laundry drying cycle of low-speed operation, a leading-in hot air temperature (T1) and a exhausting hot air temperature (T2) are increased together and saturated soon and the change rate of those temperatures is made 0. The rotary drum 12 is stopped and stopped drying is continued. When a part around the ventilating path for the hot air in the laundry is enough dried, the T2 starts being increased and an increase part DELTAT2 for each unit time exceeds the prescribed value, oscillating disks 15a 15b are mutually driven in reverse direction. Thus, the laundry is moved and when the ventilating path of the hot air to pass through the laundry is changed, the quantity of heat for the hot air is absorbed around the new and undried ventilating path. Accordingly, the T2 is lowered. when the DELTAT2 is less than a prescribed negative value, the oscillating disks 15a and 15b are stopped together and the stopped drying is continued again.

IPC: G06F11/30
Filed: 1985-09-06
Abstract: PURPOSE:To decrease the down-time as a system as much as possible by sending an abnormity detection suppressing signal to abnormality detector when an abnormality takes place in a computer system and a processor starts its unique fault recovery processing. CONSTITUTION:A processor 1a sends a signal periodically to an abnormality detector 2a at the normal operation. The detector 2a supervises the time interval of the input signal when the input signal does not come consecutively for a prescribed time or over, it is detected as an abnormality of the processor 1a, an abnormality detection signal is sent to the processor 1a or a processor 1b and the processor 1a stops the processing operation. When the detector 2a receives the abnormality detection suppressing signal fed when the processor 1a starts its unique fault recovery processing, the abnormality detection operation is suppressed for a time permitted for the fault recovery processing. When the processor 1b receives the abnormality detection signal, after the fault recovery processing permitting time of the processor 1a elapses, the processor 1b continues the job in place of the processor 1a. Thus, the system down-time is decreased as much as possible and the job is continued.
