Title: Nonlinear air-spring
Inventor: YOKOYAMA TAKAO
IPC: F16F9/04
Filed: 1982-03-31
Abstract: PURPOSE:To obtain optional nonlinear characteristic of an air spring in such a way that the volume of the air-spring and the contitution of air quantitly are changed by the displacement and speed of the spring respectively. CONSTITUTION:A grooved shaft 3 is fixed to a face plate 2 on one side of an air chamber 1, while a face plate 4 on the other side is connected to a conduit 6 which links an air chamber 5 to itself and additionally serves for a guide to the grooved shaft 3. When the face plate 2 is displaced in the direction of X>O, and the groove end 7 arrives at the face place 4, the air chamber 1 is cut off from the air chamber 5 because the conduit is obturated. Thus, each spring rigity due to the air in the air chamber 1 and the air in the air chamber 5 becomes larger than that when both chambers are connected together, because the volume is divided into two. In consequence, optional nonlinearity can be obtained by combining the length of the groove, the sectional area of the shaft, and the volume of the air chambers in various ways.

Title: Overcurrent drooping-point controlling system
Inventor: SATO HIROYUKI
IPC: H02M3/28
Filed: 1990-03-02
Abstract: PURPOSE:To suppress the fluctuation of an overcurrent drooping-point providing a DC-DC converter with the input voltage detecting means of a transformer and the reference value changing means of a primary current reference value, and by changing said reference value according to an input voltage detecting result. CONSTITUTION:In the excess current protecting circuit 3 of a DC-DC converter, an input current value due to a current transformer CT1, and reference voltage are compared with each other by an operational amplifier OP1. Thus overcurrent protection is performed. The reference voltage is generated by resistors RV, R6. To the resistor R6, the series circuit of a resistor R12 and the light receiving element of a photo-coupler PI1 is connected in parallel with each other. When the level of input voltage is lower than a specified level, then the output voltage of a comparator COMP2 is turned into the voltage of a low level, and the photo-coupler PI1 is turned OFF. When the input voltage is made higher, then the photo-coupler PI1 is turned ON, and the resistor R12 is connected to the resistor 6 in parallel with each other, and the reference voltage of the operational amplifier OP1 is lowered, and an overcurrent drooping-point decreases.

Title: Chrominance signal discriminator
Inventor: ISHIMARU MASAYOSHI
IPC: H04N9/81
Filed: 1984-03-17
Abstract: PURPOSE:To secure the correct result of discrimination of chrominance signals without effect due to a fact that the level of a marker M showing the type of a chrominance signal C becomes obscure temporarily or dropped out, by detecting the discordance of contents between a reference chrominance signal and an input chrominance signal in a prescribed number of horizontal synchronizing sections and then charging and controlling the contents of the reference chrominance signal so as to obtain the coincidence with said input chrominance signal. CONSTITUTION:As shown in the diagram, a chrominance signal discriminnating circuit 45 compares a reproduction/demodulation signal RVIN with a reference level signal VREF through a level comparator 51. When the change of a color latch output CRH caused every one H is not coincident with the change of the logic level of a chrominance discrimination output signal CD caused every one H, the output EQ of a coincidence deciding circuit 61 rises up to logic H. Thus a discordance cycle counter 63 is not cleared any more and starts counting horizontal synchronizing signals HD. Then the signal CD is delivered with repetitive inverting actions at a logic level different from the output CRH. In case the abnormality of the signal RVIN lasts over a prescribed section, the contents of the signal CD are immediately inverted. Thus it is possible to obtain the signal CD showing the signal RVIN.

The layers 2, 3 are provided on both surfaces of the substrate 1 to offset the generation of internal stresses. However, the hardness of the layers 2, 3 are set at about 400 Vickers hardness. A thin Co-Cr film 4 as a magnetization recording layer is formed to <=1mum thickness by sputtering on the smoothed surface of the layer 2, by which a vertical magnetic disc recording medium is completed. The formation of the film 4 by sputtering is accomplished by heating the substrate 1 to 120-220 deg.C in a gaseous Ar atmosphere kept under, for example, 5 mTorr pressure. If the substrate is set in such a temp. range, the recording medium having excellent coercive force Hcv in the vertical direction and C-axis dispersion angle is obtd.
