Patent JP-S6311466-A (JP)
Title: Brake for vehicle
Inventor: SATO NAGASUKE
IPC: B60T8/26
Filed: 1986-06-30
Abstract: PURPOSE:To improve brake stability through keeping liquid pressure characteristics in constant without relation to the stepping-on speed of a brake pedal by providing a piston which fixes the operating force of a liquid pressure control valve at the early stage of a liquid pressure build-up. CONSTITUTION:At a liquid pressure control valve 1 connected between a master cylinder and a wheel cylinder, brake pressurization characteristics are made to change by catching the posture change of a car body at a piston 12 through an arm 14. Hereupon, when the second piston 16, against a spring 17, becomes above a protruding liquid pressure, the second piston 16 press-contacts the piston 12 and arrests its movement. Under an ordinary control operation, the break point and gradient of liquid pressure fall because of the downward movement of the arm 14 caused by the pitching of a vehicle, but under a predetermined liquid pressure, the movement of the piston 12 is arrested, and therefore the break point and gradient of liquid pressure do not change. Also, when a brake pedal is suddenly stepped on, the same operation is acted on, and so a stable control characteristic is realized without being affected with the stepping-on speed of the brake pedal.

Filed: 1987-06-19
Abstract: PURPOSE:To provide an inexpensive and small-sized superconducting device having simple construction comparable with that of a transistor or electronic tube, by utilizing an electronic cooling element as cooling means and packaging it integrally with a superconducting material while connecting them with external circuits. CONSTITUTION:A superconducting element 1 is disposed on a cooling device 2 having a built-in electronic cooling element making use of Peltier effect of a semiconductor. The cooling device 2 is secured on the inner surface of the bottom wall of a package 3 and connected with an external conducting circuit through leads. The superconducting element 1 is also connected with an external circuit through leads so that signals are inputted or outputted through the paths thus provided. By energizing the electronic cooling element in the cooling device 2, the temperature of the cooling device 2 is lowered and hence the temperature of the superconducting element 1 thermally connected therewith is also lowered to an operating temperature. In this manner, it is possible to operate a superconducting material with simple construction and simple control. Accordingly, a device presenting superconductivities can be put in practical use at a reasonable cost, while minimizing the size of the device.

Abstract: PURPOSE:To detect a frequency offset of a signal subject to phase modulation accurately by detecting a peak of data of a histogram generated by a histogram generating means and outputting a frequency error component corresponding to the peak. CONSTITUTION:A differential phase discrimination error DELTAomegasTs obtained by a subtractor 3 is fed to a histogram generating circuit 11, in which a probability distribution of the differential phase discrimination error is plotted as a graph. The generated histogram data are fed to a maximum value detection circuit 12 and an area conversion circuit 13. The circuit 12 detects a maximum frequency (m) and it is fed to the circuit 13. The circuit 13 implements histogram data area conversion from the circuit 11 and converts the data into values within a range of m-(pi/4) to m+(pi/4) around the maximum frequency (m) from the circuit 12. The histogram subject to range conversion are sent to an averaging circuit 5, from which a frequency offset DELTAomega is obtained by averaging and DELTAomegais fed to an output terminal 6. Thus, the obtained frequency offset An is an accurate value in which the averaging processing in the circuit 5 is correctly implemented.

Abstract: PROBLEM TO BE SOLVED: To ensure stabilized speed control by performing voltage control using a low DC voltage produced from a chopper circuit as a self power supply, generating a speed pulse and a speed command voltage from the low DC voltage and driving a brushless motor variably, thereby simplifying the circuitry and the wiring. SOLUTION: In a high voltage driven brushless motor, a chopper circuit 14 built in a motor 1 serves as a low voltage power supply and a high DC voltage is converted into a low DC voltage without requiring any transformer. A pre-drive circuit built in the motor 1 controls the chopper circuit 14 to detect the rotational speed of motor 1 and generate a speed pulse 12 as a self power supply. A motor drive circuit 19 is then subjected to PWM control by a speed command voltage 11 generated from a motor speed control circuit 7 depending on the speed pulse 12 and the output voltage from the chopper circuit 14 thus controlling rotation of the motor 1 appropriately. According to the arrangement, a special low voltage power supply circuit and a power supply for operating a predrive circuit can be eliminated.
