Title: Code error detecting system
Inventor: YAMADA JIYUNICHI
IPC: H04L25/49
Filed: 1984-03-26
Abstract: PURPOSE:To simplify the structure of a code error detector by inserting a ''1'' signal to a binary digital signal every (m) bits and detecting a code error by means of said ''1'' signal. CONSTITUTION:To apply the (m+1)/m-fold speed conversion to a binary digital signal supplied to an input terminal 11 together with insertion of a ''1'' signal. Then the sum component conversion of a divisor 2 is applied to said digital signal to transmit. Receiving this sum component conversion signal, the receiver side applies the differential conversion to this signal. A detestion circuit 5 checks only the ''1'' signal in the differentially converted signal. Then a code error is decided when the ''1'' signal is detected as ''0''. Thus a code error can be detected earlier than a conventional parity check system. In addition, a miniature and simple structure is attained for the circuit 5.

Title: Tape take-up mechanism for magnetic recording and reproducing device
Inventor: TOKUMOTO AKIRA
IPC: G11B15/30
Filed: 1987-03-16
Abstract: PURPOSE:To keep tape tension almost at a constant value even at the time of reviewing and to obtain a stable head touch capacity at a cylinder part equipped with a rotary magnetic head, by changing the take-up torque of a reel board on a supply side corresponding to the winding diameter of a tape. CONSTITUTION:A force transmitted from a gear 12 to an input side gear 6 is transmitted to the reel board 3 by the magnetic forces of a metallic piece 5 and a magnet 9 provided on planes confronting with each other via an output side gear 8. A spherical member 7 is inserted and arranged between planes confronted oppositely of the input side gear 6 and the output side gear 8 with an oblique plane of an angle (alpha). When the spherical member 7 is displaced in a radius direction corresponding to relative angular velocity between both gears 6 and 8 and an interval between both gears is changed from h1 to h2, the magnetic force between the bears is also changed. Therefore, since the take-up torque of the reel board 3 can be changed corresponding to the take-up diameter of the tape, it is possible to keep the tape tension from the start to the end of tape winding at the time of reviewing constant.

Title: Ink jet recorder
Inventor: AMAMIYA ISAO
IPC: B41J2/14
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To realize high recording speed by an arrangement wherein a supporting member supports an ultrasonic wave generating means without touching a piezoelectric element so that the time to be elapsed after driving the piezoelectric element before jetting an ink droplet is shortened. SOLUTION: Since the air or an inert gas, when necessary, can be present normally between a piezoelectric element 12 and a supporting member 11, an interface for canceling an ultrasonic wave radiated from an ultrasonic wave generating means to the supporting member side through such substance is formed on the rear side of the piezoelectric element 12. Consequently, ultrasonic wave is not radiated substantially from the piezoelectric element 12 to the rear side and vibration of the piezoelectric element 12 is not damped and thereby an ultrasonic wave having very large amplitude is radiated to an acoustic lens constituting an ultrasonic wave converging means 18 and into ink liquid. Similar effect is attained when the space at the noncontact position of the piezoelectric element 12 and the supporting member 11 is sustained in vacuum state.

Filed: 1999-03-05
Abstract: PROBLEM TO BE SOLVED: To detect a precise key position by providing an operation means for obtaining positions of respective objects or values corresponding thereto based on physical amounts of respective objects and an actual measurement result for every object stored in a storage means and the like. SOLUTION: A first storage means stores a relation between the physical amounts Sa and the object position K when the physical amounts Sa is the first maximum value. The operation means obtains the object position K or the value corresponding thereto based on the relation between the second maximum value LM2 and the first maximum value LM1 of the physical amount Sa, the contents of the storage means and the measured physical amount Sa.  By such a configuration, since the object position K for the physical amount Sa is stored, and the key positions K of respective objects or the values corresponding thereto are obtained based on the physical amounts Sa of respective objects and the actual measurement result for every object, different detection characteristics of physical amounts are compensated for every object, and the key position K or the value corresponding thereto is obtained accurately.
