Abstract: PURPOSE:To reduce the variance of output DC voltage and to improve stability of an amplifier, by connecting a preamplifier directly to a main amplifier when an amplifier circuit containing a preamplifier and a main amplifier is constituted with a monolithic UC. CONSTITUTION:The electric signal extracted through a magnetic head 7 is fed to an input terminal of a preamplifier 5 and then supplied to the base of a transistor TR8. TR8, 10, 12 and 14 form a differential amplifier circuit of Darlington connection. This amplifier circuit is earthed via a resistance 16 through the base  of the TR14 which is paired with the TR8 and connected to the collector of the TR12 via a resistance 15. The collector of the TR12 functions as the output terminal of the amplifier 5 and connected directly to an amplifier 6. The voltage VO at the collector terminal of the TR12 is set as VO=VR16[1+(R15/R16)], where VR16 shows the terminal voltage of the resistance 16 and R15/R16], where  VR16 shows resistance values respectively. Then VO is used as the bias voltage of the amplifier 6, and therefore the output DC voltage can be reduced sufficiently to increase the stability for an amplifier circuit.

Abstract: PURPOSE:To prevent a friction brake and its interlocking mechanism from being broken by providing a narrow hole between the pump port side and tank port side of the valve main body, for communicating a switching valve and both of the ports. CONSTITUTION:When the push pin 20 of a hydraulic control valve 17 is pushed down by manual operation a hydraulic valve opening 4 is closed in sequence by a switching valve 5, and hydraulic pressure within a return oil passage is raised in sequence to expand the piston of a cylinder, and the braking force of a friction brake is gradually increased to brake a running device. After the hydraulic valve opening 4 is completely closed by means of the switching valve 5 by fully pushing down the push pin 20, a transverse oil hole 24 located beneath the piston 22 is communicated with a narrow hole 6, and a part of hydraulic pressure is discharged from the narrow hole 6 to the side of a tank port 3, and hydraulic pressure within the return oil passage is raised only by the differential pressure caused by the narrow hole 6 and will not be raised to the set pressure of a main relief. The upper limit pressure of the friction brake can thus be preset by means of the size of the narrow hole 6 and it is possible to prevent the friction brake and its interlocking mechanism from being broken.

Abstract: PURPOSE: To hold a braking force during the predetermined time even after a brake pedal is released by a method wherein a projected swaying member made of an elastic body, with which the  gap between a valve seat and a valve body is closed due to the pressure difference around the  gap, is provided at either the valve seat or the valve body, both of which consist of the vacuum  valve of the vacuum servo device.   
     CONSTITUTION: When the brake pedal is operated, the braking operation is performed in the  same manner as in an usual vacuum servo device: that is, a rod 36 is moved leftwards, the  vacuum valve is closed, an air valve is opened, the atmospheric pressure is introduced to the  changing pressure chamber of a braking device and the power piston is actuated to apply braking. When the brake pedal is released to take off braking, a valve plunger 37 is moved rightwards to  close the air valve 40. When the plunger 37 is moved further rightwards, the tip of the projected swaying member 32 of the valve seat 31 is swayed outwards keeping in contact with the valve  body 30 due to the condition that the inside of the changing pressure chamber 28 is kept at the  atmospheric pressure while the inside of the negative pressure chamber 27 and the side of a port  46 are kept at the negative pressure and the delayed parting of the member 32 from the valve  body 30 behind the time of operation of the brake pedal is resulted.
