Title: Reproducing amplifier circuit
Inventor: YOSHIOKA ATSUSHI
IPC: H03F1/34
Filed: 1984-03-23
Abstract: PURPOSE:To form constitution suitable for a VTR with high definition by providing an FM equalizing circuit comprising a transversal filter using a delay line so as to supplement deficiency of boost amount after an output of two video heads is amplified and added. CONSTITUTION:A reproduced output of video heads 2a, 2b is inputted to reproducing amplifiers 10a, 10b and amplified. The resonance characteristic between input capacitors such as capacitors C<5>, C6 of an input section and an inductance L of heads 2a, 2b is set to an optimum value by adjusting the capacitors C5, C6 or the value of a damping resistor in parallel. After outputs of the amplifiers 10a, 10b are added (5), the result is inputted to the FM equalizing circuit 11 comprising the transversal filter using the delay line. Thus, the deficient boost is supplemented to the signal, sufficient FM is applied and the result is transmitted to an FM demodulation circuit.

Title: Key of keyed instrument
Inventor: KAIJIMA MASANOBU
IPC: G10B3/12
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To hold a fingertip at an accurate position, and push a key with accurate strength, and improve a performance characteristic by installing a rubber sheet on a push-key surface of a key in the key swingably supported with a key support member. SOLUTION: A key 10 is composed of a key main body 11 fabricated by a resin or wood and a rubber sheet 12 installed on a push-key surface 11a of this key main body 11. The key 10 is swingably supported with a key support member. In the rubber sheet 12, a thickness is preferable to be set to 10 to several hundred μ for practical use. When it is thinner than 10μ, an effect is not fulfilled, and when it is thicker than several hundred μ, a smooth movement of a finger is checked, and a performance is hindered. Since useless power must be added, an evil influence such as a player easily gets tired and a touch feeling is bad is exerted.  By this constitution, a finger hardly slips on the key 10 of a keyed instrument, and a movement of a fingertip can be stopped at an accurate position, and since the key can be pushed with accurate strength, a performance characteristic can be improved.

Title: Electrophotographic sensitive body
Inventor: TANIGUCHI KIYOSHI
IPC: G03G5/047
Filed: 1987-03-09
Abstract: PURPOSE:To enhance sensitivity and to lessen the degradation in electric chargeability arising from pre-exposing fatigue by incorporating fatty acid ester of cane sugar into a layer in which an electric charge generating material is dispersed. CONSTITUTION:An electric charge generating layer 1 and charge transfer layer 2 are successively laminated on a conductive base 3. The fatty acid ester of cane sugar is incorporated into the layer 1 in which the charge generating layer is dispersed. Namely, the fatty acid ester of cane sugar is chemically adsorbed in the charge generating material and provides the recombination center of the charges generated by light absorption and, therefore, the charges generated by the pre-exposing fatigue are quickly recombined and are thereby annihilated, conceivably by which the drop of the charge potential of the photosensitive body is suppressed. The electrophotographic sensitive body which has the high sensitivity, extremely lessens the degradation in the electric chargeability arising from the pre-exposing fatigue and obviates the drop of the charge potential even after repetition of the electrical charging and exposure is thereby obtd.
