Inventor: KOBAYAKAWA YOSHI
IPC: A61B3/10
Filed: 2000-05-11
Abstract: PROBLEM TO BE SOLVED: To simply constitute an index projection system of a corneal shape measuring mechanism and to improve its operation. SOLUTION: A luminous flux from a light source 38 is incident to a movable optical member 334 via an incident optical member 36. A part of the flux is reflected on an adhering surface of an optical member 35 and the other is incident to a flat plate-like optical member 1. The flux is advanced while reflecting on inner surfaces of the members 1, 34, diffused when the flux is contacted with light diffusing parts 32, 39, reflected at ends of the members 1, 34, and returned. The fluxes diffused in the parts 32, 39 illuminate the cornea of an eye E to be inspected with the parts 32, 39 to become secondary light sources. Since the parts 32, 39 are constituted in a ring-like state at a center of an optical path 01 as a center, the flux reflected on the cornea is imaged by an imaging means 8 to form a ring-like reflected image R on a television monitor 19.  This image R is analyzed to obtain the corneal shape.

Title: Image recording equipment
Inventor: HARADA AKINORI
IPC: B41M7/00
Filed: 2000-05-16
Abstract: PROBLEM TO BE SOLVED: To increase processing speed when image recording is carried out using a photosensitive and heat sensitive recording material. SOLUTION: A heater 50 heats a photosensitive and heat sensitive recording material 12 while the recording material 12 is irradiated with light of light sources 48 for fixation. Since photo-fixation and photo-decoloring are carried out under heating, the viscosity of the system lowers and the diffusibility of active radicals increases. By this radical activity, a photopolymerization reaction and a photo-decoloring reaction are accelerated and fixing and decoloring efficiencies are enhanced.

Title: Portable electronic device
Inventor: ISODA MORIO
IPC: H04M1/02
Filed: 2000-05-19
Abstract: PROBLEM TO BE SOLVED: To provide a portable electronic device which is lessened in material cost, weight, and thickness and capable of improving its function to prevent its keys from being erroneously operated by a method wherein a cover is formed so as to have a convex surface that bulges out and pivoted rotatably in a portable electronic device in the direction of development. SOLUTION: A cover 17 is formed as a whole so as to have a convex surface that bulges out. Furthermore, a part of the cover 17 is made to bulge out further, and a stepped part 18 is provided nearly at the center of the cover 17. As the stepped part as a section shape is provided on the cover 17, the cover 17 is increased in single layer second moment of area and bending rigidity. Furthermore, the cover 17 itself is formed like a convex surface, so that a distance between the inner surface of the cover 17 and function keys 5 and dial keys 6 becomes large when the cover 17 is closed, and a gap tolerance for the deformation of the cover 17 becomes high.  Even if an external force is applied to the cover 17, the cover 17 is hardly elastically deformed because it is increased in rigidity, so that the cover 17 is prevented from pushing down the function keys 5 and the dial keys 6 or coming into contact with them.

Title: Light image measuring device using two-dimensional heterodyne detecting method
Inventor: CHAN KINPUI
IPC: G01B11/24
Filed: 2000-05-25
Abstract: PROBLEM TO BE SOLVED: To provide a light image measuring device which can effectively detect in parallel light signals by using a two-dimensional heterodyne detecting method. SOLUTION: This light image measuring device comprises an interference optical system, a frequency shifter, light cutoff devices 7, 9, light sensors 8, 10 and a signal processing part. In the interference optical system, a light beam, which is emitted from a light source 1, is divided into two parts, i.e., a signal light and a reference light. An interference light is generated by superposing each other the signal light and the reference light. The frequency shifter shifts frequency of the reference light relative to frequency of the signal light. The light cutoff devices 7, 9 generate two series of interference light pulses, whose phase difference is 90 degrees, by synchronously cutting off the interference lights divided into two parts. The light sensors 8, 10 respectively receive the two series of interference light pulses.  In the signal processing part, a plurality of light receiving signals, which are detected by the light sensors, are integrated. A subject 5 to be detected is arranged on an arrangement position. Signals of a surface layer or an internal layer of the subject 5 to be detected, which correspond to points of concern on a propagation path of the signal light, are generated.

IPC: A63F5/04
Filed: 2000-05-31
Abstract: PROBLEM TO BE SOLVED: To improve game property by stopping a rotating reel in one of a stop mode out of two or more stop modes in a prescribed internal state. SOLUTION: When a prize is won (a prescribed internal state is obtained) in a bonus game in this game machine such as a slot machine, the rotating reel is stopped at either reel control (the stop mode) out of a first reel control or second reel control (two or more stop modes) (steps S72, S74, S76). In the case of a failure (a prescribed internal state), the rotating reel is stopped at either reel control out of a third reel control or fourth reel control (steps S82, S84, S86). The internal state and reel control do not therefore correspond to each other to cause a surprise, so that interest in operating a stop button (a second operating part) is increased to improve game property.

Title: Communication monitoring control for preventing rf signal interference in information processing apparatus having a plurality of radio communication parts
Inventor: SHIOZU SHINICHI
IPC: H04B17/00
Filed: 2000-06-01
Abstract: PROBLEM TO BE SOLVED: To achieve an information processing apparatus with radio communication function which can evade or sufficiently reduce RF signal interference by a simple method when communication is performed between a plurality of information processors having radio communication function. SOLUTION: The information processing apparatus (10) is equipped with a first and a second radio communication parts (12, 13) and a communication monitoring control function part (11). When the first radio communication part (12) performs communication, the function part (11) monitors the state of communication of the second radio communication part (13), and adjusts the transmitting condition of a radio transmitter-receiver of the first radio communication part, in accordance with the state of communication of the second radio communication part. For example, when the second radio communication part is about to make connection or during connection, the function part (11) decreases transmission output power of the transmitter-receiver of the first radio communication part.  When the second radio communication part is not going to make connection or is not during connection, the function part (11) increases transmission output power of the radio transmitter- receiver of the first radio communication part.
