Title: Servo circuit for motor for driving rotary magnetic head
Inventor: KIMURA SATOSHI
IPC: H04N5/783
Filed: 1987-10-16
Abstract: PURPOSE:To make the frequency of a horizontal synchronizing signal reproduced by a rotary magnetic head constant even when the running speed of a magnetic tape is changed by providing plural phase comparator circuits to a phase servo circuit so as to switch them by a changeover switch. CONSTITUTION:A phase comparator circuit 7 is provided to a phase servo circuit 12 in addition to a phase comparator circuit 4. Then a comparison output from the circuit 4 is fed to a fixed contact (n) of a changeover switch 6 and a comparison output from the circuit 7 is fed to a fixed contact (s) of the switch 6 and an output of a moving contact (a) is fed to a drum motor 1 via a mixing circuit 5. In this case, the contact (a) of the switch 6 is thrown to the position of contact (n) at the reproduction when the magnetic tape is driven at a steady speed and the contact (a) is thrown to the position of the contact (s) at the high speed search when the tape is fed fast or rewound or at variable speed reproduction at a constant drive speed. Thus, even when the tape running speed is changed, the frequency of the horizontal synchronizing signal reproduced by the rotary magnetic head is made constant and the color reproduced picture is obtained even at high speed search.

Title: Vehicle anti-skid brake
Inventor: OKAZAKI HARUKI
IPC: B60T8/1761
Filed: 1990-09-27
Abstract: PURPOSE:To stop a vehicle quickly at a short brake distance by changing the threshold of brake pressure control so that brake efficiency may become high, when a detected steering wheel turning amount is excessively large. CONSTITUTION:A brake pressure adjusting means 2 is controlled by means of a control means 3 so that brake pressure may be increased/decreased according to a predetermined control threshold on the basis of a vehicle wheel speed detected by means of a vehicle wheel speed detecting means 1. A control threshold value is changed by means of a control threshold value changing means 5 so that the brake efficiency of vehicle wheels may become high when a steering amount detected by means of a steering amount detecting means 4 is more than a predetermined value. Thus, in the case of an operater falling into a panicky state and operating a steering wheel excessively, a vehicle can be stopped at a shorter distance than the usual one by changing a control threshold value so that brake pressure may act on the vehicle wheels more on the side of locking than the usual one, that is, the brake efficiency of the vehicle wheels may become high.

Title: Spindle construction for disk device
Inventor: SATO TAKAKORE
IPC: G11B17/038
Filed: 1990-09-28
Abstract: PURPOSE:To prevent off-track by arranging plural ring spacers whose outside diameters are smaller than the outside diameter of a spacer ring between the disk build-up surface of a spindle housing and the lowermost disk. CONSTITUTION:Two pieces of the ring spacers 16 whose outside diameters are smaller than the outside diameter of the spacer ring 8 are arranged at the lower side of the spindle housing side 2 end part of a magnetic disk 1, that is, between the disk build-up surface of the housing 2 and the lowermost disk 1. When the temperature of a magnetic device changed, temperature difference is caused between the disks 1 at both ends and the other disks, and the stress of fixed parts in contact with the spacer ring 8 become different. Accordingly, by making the spacer 16 smaller than the outside diameter of the ring 8 so that a contact surface with the disk 1 is made smaller, restriction force to the lowermost disk 1 is reduced, and simultaneously, the stress is relaxed among the spacers 16, and deformation is prevented, and the off-track due to the lowermost disk 1 is prevented.

Title: Educationally unspecified 'kanji' detecting/correcting mechanism in japanse word processor
Inventor: KOIKE NORIKO
IPC: G06F17/22
Filed: 1990-09-28
Abstract: PURPOSE:To improve the accuracy of calibration by providing this educationally unspecified 'KANJI' (Chinese character) detecting/correcting mechanism with a detection part for detecting educationally unspecified 'KANJI'(EUK), an educationally specified 'KANJI'(ESK) dictionary to be used for the detection of an EUK character by the detection part and a correction part for correcting a detected EUK character. CONSTITUTION:The detection part 12 collates the leading KANJI 'SUI' (means 'water' in English) of document data with KANJI characters consisting of KANJI characters 'SUI ON' (means 'water temperature' in English) stored in the ESK dictionary 11 and decides whether the KANJI 'SUI' is a KANJI character other than KANJI characters educationally specified as the ones to be learned in the 2nd grade or not. Since the KANJI 'SUI' is a KANJI character to be learned less than the 2nd grade as the result of decision, the succeeding KANJI 'ON' (means 'temperature' in English) is similarly decided. When the detection part 12 decides that the KANJI 'ON' is a KANJI character to be learned other than the 2nd grade, the correction part 13 underlines the KANJI character other than the ones to be learned in the 2nd grade out of the document data and a cursor is allocated to the position, so that the detecting position can be cleared and the EUK 'ON' is displayed and informed to a document former. The correction part 13 automatically corrects the document data by a changing candidate and updates the document data by the corrected result. Consequently, a working time is shortened and the accucary of calbration is improved.

Title: Coordinate input device
Inventor: KOBAYASHI KATSUYUKI
IPC: G06F3/043
Filed: 1988-10-20
Abstract: PURPOSE:To prevent the interference of vibration, and to detect a correct coordinate by providing a supporting member which is in contact directly with a vibration transmission plate through a surface and supports the vibration transmission plate, and setting the vibration transmission speed of the supporting member slower than the vibration transmission speed of the vibration transmission plate. CONSTITUTION:The vibration transmission plate 8 is made of glass, and the supporting member 30 is made of the material of acrylic resin, etc. When the vibration is impressed upon a point A on the vibration transmission plate 8 from a vibration pen 3, the state of the vibration becomes like 2A. Besides, when the vibration passes through the member 30, the vibration like 2B is excited. On the assumption that the head of the inputted vibration of the transmission plate 8 reaches the point C after certain time elapses, the state of the vibration becomes as shown by 2C. If the speed of the transmission in the transmission plate 8 of a wave propagating in the member 30 is slow, it becomes like 2E. Thus, by making the transmission speed in the member 30 slower than the transmission speed in the transmission plate 8, waveform to be detected at the point C is never influenced even if the transmission plate 8 is arranged, and the distortion of a signal to be detected by a vibration sensor can be made smaller, and correct vibration detecting timing can be obtained.
