Title: Transmission abnormality treatment
Inventor: OTSUKA TOSHIHIKO
IPC: H04L12/40
Filed: 1990-11-16
Abstract: PURPOSE:To improve the transmission efficiency of a transmission system as a whole by adding a carrier detection circuit to show it at a command station that a receiving data is under reception, checking a carrier detection status in the case of reception monitor time over, and resetting a reception monitor timer again as needed. CONSTITUTION:When the command station transmits a command to a response station, the maximum value of response station transmission processing time is set to a reception monitor timer 6 of the own station. When the reception is completed, the command station executes a normal reception processing and when the reception monitor time gets over, however, a carrier detection circuit 14 is checked. When the data is under reception, the maximum response data transmission time is set to the reception monitor timer 6 again and the completion of reception is waited for. When the data is not under reception, transmission error is judged and the transmission of the command is similarly executed to the next response station. Thus, in the case of transmission abnormality, the transmission abnormality processing of the command station is made shortest, transmission efficiency is prevented from being adverse by transmission error, and efficiency is maintained for normal transmission between stations.

Title: Antiskid device for auxiliary brake
Inventor: TAKEDA NOBUYUKI
IPC: B60T8/176
Filed: 1986-12-24
Abstract: PURPOSE:To prevent locking of a drive wheel, by providing a drive wheel rotation speed detecting means, a means, calculating a slip rate based on a detecting rotation speed, and a means, disengaging a clutch when the slip rate exceeds a first given value, and engaging a clutch when decreased over a second given value. CONSTITUTION:Since it is decided whether lock may occur by directly monitoring the rotation state of a drive wheel 11 by which to cause lock, compared with a conventional type which decides from a car speed and the like, further precise decision is practicable. When it is decided that lock is going to occur, a clutch is immediately disengaged, since the drive wheel is released from not only the brake force of an auxiliary brake but also a brake force exerted due to the inertia mass of an engine, a time in which the drive wheel is returned from a state approximately similar to lock to its original state is shortened. This constitution prevents the occurrence of lock, and development of lock to jack-knifing phenomenon, brake hopping phenomenon, or irregular turn phenomenon.

Abstract: PURPOSE:To realize polarization inversion gratings having an ideal rectangular shape by impressing an electric field by a DC high voltage between electrodes facing each other on the front surface and rear surface of a substrate. CONSTITUTION:The electric field is impressed between a metallic mask electrode 52 periodically patterned at a distance L with segments bored with rectangular holes of a width W and length (d) on the front surface of the +C surface which is a direction 16 of the spontaneous polarization of an LiNbO3 substrate 11 and the electrode 53 formed with a metallic film over the entire surface of the -C face in such a manner that a positive potential is attained on the positive side of the spontaneous polarization and a negative potential on the negative side between the electrodes 52 and 53. As a result, the directions of the spontaneous polarization cause polarization inversion 12 in all of the thickness direction of the substrate in opposite directions in the certain parts of the patterns of the electrode 52. The high voltage is applied in the state of immersing the entire part of the substrate in a high vacuum or an insulating liquid in order to control discharge.

Title: Whistle for athletic tool
Inventor: ROORANDO BETSUKAA
IPC: A63B69/38
Filed: 1987-12-10
Abstract: PURPOSE: To provide a whistle for sports article allowing precisely adjusting of angle by arranging a whistle sound structure in which air flows to a through path to generate a whistle sound and a holding means to detachably link the body of the whistle to the article so that the inlet surface of the through path is kept in the direction almost orthogonal to the direction of motion. CONSTITUTION: A base surface 9 of a whistle 1 has a circular groove 10 extending on the circumference thereof and a shaft 11 vertical to a horizontally symmetrical plane 12 of the whistle almost coinciding with a through hole 3. The groove 10 has a dimension enough to receive a gut 13 of a racket and is held at an appropriate point by the gut 13 during the contest. Where the plane formed by the gut of the racket is set vertical to the direction of the racket moves, cone shafts 15 and 16 are both parallel with the direction of the movement of the racket. As a result, compressed air forcibly passes through the through path 3 to generate a whistle sound. This 'right angle' direction of the racket is preferable for straight shot of a ball thereby achieving a correct swing. Thus, when the hitting of the ball is done correctly and also at a favorable speed, a whistle sound is generated.
