Abstract: PURPOSE:To enable loading from the head of a file in a medium such as a magnetic tape, etc., without being conscious of the function of the file in the medium in the case of storing the file by executing the selective control of loading while discriminating whether each combined file of the program preserving medium is related to the offering function or not. CONSTITUTION:The prescribed kinds of combined files are provided while estimating the combination of functions to be offered form each system to a program preserving medium 10 in advance, and at the time of loading, the offering function relation discriminating means 121 of a load execution part 12 identifies the relation between each combined file and the offering function of each system. When there is no relation, loading is not executed and when there is any relation, loading is selectively executed while collating the file with the function of the stored file. When the combined file of the program preserving file includes the stored file, the stored file is overwritten. Thus, even when loading is executed concerning all the files stored in the medium 10, it is not necessary to be conscious of the function, and the area of the medium to store the file is effectively utilized.

Title: Gas pressure booster for brake
Inventor: TANAKA TOSHIHIKO
IPC: B60T13/573
Filed: 1991-02-07
Abstract: PURPOSE:To provide a gas pressure booster for a brake which changes a boosting ratio in two stages and has excellent durability of a reaction disc. CONSTITUTION:During forward movement of a power piston, a subplunger 94 is first brought into contact with a reaction disc 78, and boosting is effected with a high boosting ratio when an input is high. When an input is increased, the subplunger 94 is gradually retracted in a plunger body 86 as a resistance force increased with the increase of the reaction force of the reaction disc 78 is exerted on the subplunger from a rubber block 98. Finally, the plunger body is brought into contact with the reaction disc 78 in a state that the plunger body 86 is positioned flush with the subplunger 94, and a boosting ratio is decreased. Unreasonable deformation does not occur to the reaction disc 78 in a region where a force is high and service-life is prevented from decreasing.

The material having the m.p. higher than the m.p. of the protective layer on the lowermost protective layer is used for the lowermost layer and the upper protective layers are laminated into >=1 layers thereon to make the lowermost layer 3 hardly strippable even if the upper protective layer exfoliates. The corrosion and wear of the film 2 are thus prevented and the long period recording medium is obtd.

Abstract: PURPOSE:To improve the characteristic of a low frequency sound at a large sound volume by controlling the resistance in a capacitor, an inductor and a resistor connected to a negative feedback input terminal of a low frequency amplifier circuit in response to the output of a display device of the attenuation. CONSTITUTION:As the attenuation of an electronic volume circuit 2 decreases, a DC output voltage at a terminal 8 gets higher and attenuation display LEDD1-D5 of a display circuit 5 are lighted in the order of D1 D5. The gain of a voltage amplifier circuit 1 is decided by a ratio of a capacitance of a capacitor C2, an inductance of a simulate inductor 6, a combined resistance of a resistance switching circuit comprising resistors R3-R5, FETs Q1, Q2, an impedance of a series resonance circuit and a resistor R1 under the condition of R2>>R1, R6>R1 and C1>>C2. When an LED at a high-order is lighted, the resistor is switched in increasing direction to decrease the Q of the series resonance circuit thereby suppressing the intensity of the low frequency sound. Thus, the distortion of the low frequency sound at large sound volume is improved.
