Title: Eectronic brake management system with manual fail safe
Inventor: GANZEL BLAISE J
IPC: B60T8/173
Filed: 1997-03-07
Abstract: An improved electro-hydraulic brake system (10) having features for improving the pedal feel of the system, while further having design features which contribute to the economy of manufacture of certain components of the system. The system provides for an electrically powered normal source (42) of pressurized hydraulic brake fluid, and a manually powered backup source (12) of pressurized hydraulic brake fluid to the vehicle brakes in the event of failure of the normal source. During normal braking, fluid from the backup source is redirected from the vehicle brakes to a pedal simulator. The pedal simulator (26) preferably includes arrangements of spring loaded pistons, expansion volumes, and damping orifices, together with valves selectively controlling the flow of fluid to and from the pedal simulator which provides for an improved pedal feel during vehicle braking. The brake system of the invention further includes a relatively low cost fluid separator unit which is provided which prevents intermixing of pressurized fluid between the backup source and the normal source. The fluid separator unit acts to permit the normal source to act upon the hydraulic brake fluid to the backup source to operate the vehicle brakes. The fluid separator unit is preferably embodied as a piston having two working faces, each of the same diameter.

Title: Variable frequency divider
Inventor: YAMASHITA KIICHI
IPC: H03K23/66
Filed: 1982-01-27
Abstract: PURPOSE:To set an optional frequency division number by cascading a high- speed frequency divider and a low-speed frequency divider. CONSTITUTION:A variable frequency divider consists principally of a front- stage variable frequency divider 101 which operates at a high speed, a main variable frequency divider 102, and a frequency division number selector 103 which selects a frequency division number. This variable frequency divider selects two kind of frquency division numbers of the front-stage varaible frequency divider 101 which uses a signal supplied to a terminal 1 as a clock through the frequency division number selector 103 and those two kind of frequency division numbers are switched by the output of the main variable frequency divider 102 to obtain a prescribed frequency division number at a terminal 2. For this purpose, a QM is set invariably to a level 0 by an output  selection signal supplied from a terminal and thus a signal fed back to the front- stage variable frequency divider 101 from the main variable frequency divider  102 is intercepted to put two frequency dividers in independent operation.

Title: Electronic scanning antenna
Inventor: SHIRAMATSU KUNIAKI
IPC: H01Q3/38
Filed: 1983-01-25
Abstract: PURPOSE:To decrease the side lobe produced by a quantized phase error at beam scanning by adjusting a phase of an input signal of a phase shifter stepwise as specified with a phase adjuster and setting the amount of adjustment of the phase shifter to a prescribed value. CONSTITUTION:The phase of an input signal of the phase shifter 2i relating to the i-th element antenna 1i is adjusted stepwise as expression I based on the phase of an output terminal of a transmitter 7, for example, by using the phase adjuster 9i, where alpha is an optional constant, i=1, 2-, (n), (m) is a natural number, and [X]D is a value formed stepwise by a step width of D closest to the X. In setting the amount of phase shift of the phase shifter 2i by a control signal from a control circuit 5 as shown in expression II, the phase of a signal applied to the element antenna 1i is expressed as expression III, where [X]B is digital phase amount quantized by B closest to the X, beta is a constant corresponding to the beam scanning angle, and B and D are minimum unit phase angles. Thus, the side lobe produced by the quantized phase error at beam scanning is reduced.
