Title: Overturning preventive device using reverse rotation of gear
Inventor: MIURA MICHIAKI
IPC: B63B43/02
Filed: 2001-07-16
Abstract: PROBLEM TO BE SOLVED: To provide a small, lightweight, and strong overturning preventive device effective in preventing overturning of an unstable object floating on the water such as a canoe, a yacht, and a ship. SOLUTION: For imparting the strong overturning preventive function, the rotation ratio of a gear having high power, and capable of applying a lever is set by application of the lever. For minimizing extent of a space required for a shaft for supporting the gear for miniaturizing the device, not a bar-shaped shaft but a quadrangular frame-shaped shaft is used. For reducing weight of the device, reverse rotation is generated in the gear so as to dispense with gravity corresponding to torque transmitted to the shaft for supporting the gear, and a rotating speed of the gear reversely rotating to the overturning direction is increased by application of the lever. This overturning preventive device uses reverse rotation of the gear.

Title: Game machine
Inventor: KANAZAWA HIROSHI
IPC: A63F7/02
Filed: 2001-08-22
Abstract: PROBLEM TO BE SOLVED: To realize a game machine capable of preventing the change of a signal by noise outputted from a main control means to a presentation means. SOLUTION: Eight output ports of the peripheral circuit 100b of a main CPU 112 are electrically connected to the receiving circuit 200e of a sub-CPU 212 through photo MOS relays PR25-PR32, respectively. Eight output terminals of the receiving circuit 200e are connected to input ports of the sub-CPU 212 through photo MOS relays PR1-PR8, respectively. Namely, since the photo MOS relays have a long switching speed up to about 1 ms, there is no possibility that a prize ball delivery control command changed by noise is input to the sub-CPU 212. Accordingly, since prize balls can be precisely delivered, the disadvantage of a player by shortage of prize balls or the disadvantage of a pachinko hall by excessive prize ball delivery can be eliminated.

When the lock code is set to the initial value as it is, and a received lock code coincides with a recorded lock code, the control part 11 compares a received ID number with a recorded ID number. When the ID numbers match with each other, the mobile communication terminal 1 transfers requested data to another communication terminal. After the data are transferred, operation to a mobile communication terminal body 10 and access to an information recording medium 20 are locked.

Abstract: PROBLEM TO BE SOLVED: To provide an information recording method based on a recording strategy which can record a mark, of which the rear end is not trailed, so as to be able to cope with increase of the recording linear speed and the recording density. SOLUTION: When a mark corresponding to a period nT is recorded, the laser power level is controlled between two standard power levels P1 and P2 (P1>P2), and a period t1 for which the laser power should be kept in the power level P1 within the period nT is set within a range equal to or shorter than λ/NA/v where v, λ, NA are the recording linear speed, the wavelength of a laser beam used for recording, and the numerical aperture of an objective lens respectively, and the temperature variation is controlled by the power levels P1 and P2 of the laser beam and the pulse width t1 to form the rear end of the mark independently of recrystallization, and thus the mark length is modulated by the simple recording strategy using a single pulse having two standard power levels.  Because of this recording strategy, the mark longitudinally symmetrical in the peripheral direction of a disk can be recorded to suppress trailing of the mark rear end.

Title: Lens effect correcting device for fixed laser and its lens effect correcting method
Inventor: KATO MASAHIRO
IPC: H01S3/042
Filed: 2001-09-06
Abstract: PROBLEM TO BE SOLVED: To reduce the lens effects of a slab by realizing the harmonic matching of the both factors of a heat insulator and a light source, and adjusting the temperature distribution of the slab. SOLUTION: This device is constituted of a medium supporting body 1 for supporting a fixed laser oscillating medium 11, a light source supporting body 13 supported by the medium supporting body for supporting a light source 32, a heat insulator 45 interposed between the medium supporting body 1 and the fixed laser oscillating medium 11, and an adjusting mechanism for geographically adjusting the angle of a valid central face 55 of a light beam for excitation to be generated from a light source 32 by adjusting the angle of the light source 32 for the light source supporting body 13. The heat insulator 56 is interposed between a cross face crossing a light receiving face for receiving the light beam for excitation among the external faces of the fixed laser oscillating medium 11 and the medium supporting body 1.  In this case, one of the significant factors of the non-uniformity of the heat distribution of the fixed laser oscillating medium 11, especially, the surface side region lies in the existence of the heat insulator 56. The non-uniformity of the heat distribution due to the existence of the heat insulator 56 strongly depends on the unsuitability of the irradiation angle of the beam for excitation, especially, incident energy density depending on the irradiation angle. Then, the non-uniformity is validly corrected by performing geometrical adjustment of the irradiation angle of the beam for excitation.
