Title: Magnetic recording medium
Inventor: SASAKI KUNITSUNA
IPC: C09D171/12
Filed: 1984-06-25
Abstract: PURPOSE:To provide proper flexibility, sufficient mechanical strength and durability, and excellent traveling properties and to reduce the release of powder by incorporating a urethane resin having a yield point and a urethane resin without any yield points into the specified layer on a supporting body CONSTITUTION:A urethane resin having a yield point is one of the components of a resinous binder. The elongation of the urethane resin when stressed is extremely small, and the resin elongates with an increase in stress above the yielding point YP. Meanwhile, the other urethane resin to be jointly used with said urethane resin has a flexible property that the resin elongates continuously with a stress, and the property contributes to the giving of proper softness and binding force to the layer. The yield point is important to the performance of the urethane resin, and regulated in the stress range 50-600kg/cm<2>, or preferably 100-560kg/cm<2>. The resin is easy to soften at <50kg/cm<2> stress, and hardens and is fragile at >=600kg/cm<2>.

Inventor: KOSAKAI MINORU
IPC: H04N5/93
Filed: 1979-10-12
Abstract: PURPOSE:To make it possible to compensate accurately the difference in the high frequency component of a reproduced RF signal between the inner and outer circumferences of a disk without any influence of the reflectivity of the disk, by providing an automatic gain control circuit and equalizer circuit. CONSTITUTION:Since the frequency of sound information in a reproduced RF signal is relatively low, the sound information is equal in level at the inner and outer circumferences of a disk, so that the reproduced RF signal level is functioned with automatic gain control AGC8 according to the sound information signal level. Thus, fluctuation of the RF signal level due to a change in the reflectivity of the disk, fluctuations of a pickup laser output, etc., can be removed. Therefore, level fluctuations due to the above-mentioned cause, etc., are suppressed and the information signal is inputted to equalizer circuit 12, and consequently a high frequency level difference between the inner and outer circumferences of the disk can be compensated by controlling equalizer characteristics of equalizer circuit 12 accoding to only the level of the video information signal.

Abstract: PURPOSE:To confirm whether for plural bit lines or word lines, the simultaneous selecting action or the whole selecting action is actually executed by applying an AND circuit to constitute, as a gate input, a gate signal line or a word line to select the bit line, to a semiconductor memory device. CONSTITUTION:The output node A of the NAND circuit is connected to the dedicated pad PM or so that the information of the output node A can be obtained from an existing output pad P1, connected through a change-over circuit SWC to the output pad P1.

Title: Device for detecting cassette in cassette tape recorder or the like
Inventor: SATOU MASAHIRO
IPC: G11B15/17
Filed: 1982-07-28
Abstract: PURPOSE:To detect the loading of a cassette tape precisely, by using an output signal from a rotation detecting means of a tape winding driving part fitted to detect the final end of the tape or the like. CONSTITUTION:A rotation detecting circuit 18 outputs a pulse signal (b) with the frequency proportional to the turning speed of a reel motor 34. When the cassette tape is unloaded and the reel motor 34 is in the constant speed mode, the reel motor 34 is reduced at the load and rotated at a speed considerably higher than that of the loaded status of the tape. When the operation mode of a tape travelling driving system is turned to the constant speed travelling mode, a control circuit 22 executes cassette detecting processing. Namely, the number of pulses of the output signal (b) in unit time T0 is counted by a cassette existence counter and whether the counted value is larger than the previously setup reference frequency or not is discriminated. The reference frequency is set up to the intermediate value of the frequency of the output signal (b) outputted in accordance with the loaded status of the cassette tape. When frequency of the measured output signal (b) is higher than that of the reference value, the unloaded state of the cassette tape is discrminated.

Abstract: PURPOSE:To read out a record having high density and large capacity, by simultaneously irradiating optical beam to three adjacent information tracks, and subtracting the signals which have multiplied signals of both adjacent information optical beams, by the quantity of crosstalk, from a signal of the middle information optical beam. CONSTITUTION:Optical beamsI,I',I'' are used as a read out optical beam, and quantities of light for signal obtained by irradiating tracks -1, 0 and +1 are denoted as S', S and S'', respectively. These S' and S'' are multiplied by the quantity of crosstalk (k), and when its result is subtracted from S, an expression of S-kS'- kS'' (1-2k<2>)S0 is obtained. In this case, since K<2> is small enough, S0, that is to say, a signal S0 in case when optical beam has irradiated the center part of the middle track is obtained, and the quantity of crosstalk in this case becomes a decreased form. In this way, when said operation is executed the quantity of crosstalk is made small apparently, and a record having high density and large capacity is read out.
