Title: Drive in and out to pallet in multistory parking space
Inventor: OKAMOTO KOJI
IPC: E04H6/18
Filed: 1992-12-29
Abstract: PURPOSE:To prevent a pallet from jumping, to prevent an impact noise and creak from occurring, and to prevent the pallet from breaking, in the title device. CONSTITUTION:A slope plate 20 is rotatably extended at the end part of a pallet 19 for placing a vehicle, at which end side the vehicle is driven onto the pallet or from thereon and which pallet is provided so as to be movable to each story in a multistory parking space 1. Either on the side of the slope plate 20 or on the side of the pallet 19, a stopper 24 is provided, by which the slope plate 20 stops at the position where the slope plate 20 at a horizontal position rotates downward by a fixed angle. For that reason, before the pallet 19 reaches a floor 13 by lowering, the downward rotation of the slope plate 20 is restricted by the stopper 24 and the slope plate 20 is held in the condition that the top end part thereof slightly rotates downward, and thus the top end part of the slope plate 20 abuts the floor 13 at all times when the pallet 19 is lowered. In this way, the top end part of the slope plate 13 can be prevented from lifting.

Title: Wavelength conversion method for clbo crystal
Inventor: OSAKO YASUSHI
IPC: G02F1/37
Filed: 1999-12-21
Abstract: PROBLEM TO BE SOLVED: To prevent the degradation of output power and output stability in spite of a change in ambient temperature when a laser beam of <=300 nm in wavelength is generated by a CLBO crystal. SOLUTION: If the average output density of an output laser beam is successively increased when the CLBO crystal 1 is set at a phase matching θ optimum at a heating and holding temperature T, the gradient of a change in conversion efficiency when the temperature changes is relatively gentle in a region where the temperature of the CLBO crystal shown in Figure 1(b) is higher than the T described above but the change in the conversion efficiency (=output power) when the temperature changes is steep in the region where the temperature is lower than the T described above. The temperature of the CLBO crystal 1 is, thereupon, controlled to the temperature higher than the temperature T when the laser beam of >=300 nm is generated by executing the wavelength conversion by the CLBO crystal 1.  As a result, the change in the output power may be made smaller and the stability of the output higher even if the temperature of the CLBO crystal is changed by the change in the ambient temperature.

Title: Signal detecting method
Inventor: TAKATSU KAZUNORI
IPC: H04M11/00
Filed: 1999-12-21
Abstract: PROBLEM TO BE SOLVED: To provide a signal detecting method by which a periodical signal resistant to a noise without relying on a sampling phase, etc., by utilizing the autocorrelion of the periodical signal. SOLUTION: An input signal (a reception waveform) is made into a frame at every period and a convolution operation between the adjacent frames is performed. Since the tone or periodical signal to be periodically changed has autocorrelation generally, it has a nearly fixed positive value (a frame correlation value) independently of the defining method of the sampling phase or the frame. The positive value matches the energy of the signal in the frame. Since the noise (before reception) not has the same kind of period, the noise is small numerical value (an average = zero) being positive or negative even when executing the same calculation. Besides, the value is periodically changed when executing the calculation with respect to the signal having another period.

Title: Magneto-optical recording medium and its reproducing method
Inventor: SHIRAI HIROSHI
IPC: G11B11/105
Filed: 1997-12-22
Abstract: PROBLEM TO BE SOLVED: To provide a magneto-optical recording medium capable of reproducing micromagnetic domains recorded at a high density with high resolution and high C/N. SOLUTION: This magneto-optical recording medium has a macroreproduction layer 3, a gate layer 5 and a recording layer 7 on a substrate. The gate layer 5 is an intra-surface magnetized film and has a magnetic characteristic to annihilate magnetization when the prescribed region is heated to a Curie temp. or above by irradiation with reproducing light. The magnetization of the micro- recording magnetic domains 100 of a size below l/3 the spot diameter of the reproducing light is discretely transferred to the macroreproduction layer via the magnetization annihilated parts 103 of the gate layer. Since the magnetization of the recording magnetic domains 101a and 10b is shielded by the intra- surface magnetization of the gate layer, only the recording magnetic domains 100 are discriminated therefrom and are transferred to the macroreproduction layer 3.  The transferred magnetic domains are magnified by impression of a reproducing magnetic field Hex and amplified regenerative signals are detected from the magnified magnetic domains 107.
