IPC: H04B1/034
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To easily improve the generation accuracy of a remote-control carrier signal without using a reference clock by a high-speed oscillator or sharply increasing the circuit scale.

Title: Modulator for anti-skid brake control device
Inventor: TAKASAKI YOSHIYASU
IPC: B60T8/48
Filed: 1993-02-25
Abstract: PURPOSE:To improve the ABS control performance by enhancing the responsiveness of a flow adjusting valve for ABS control. CONSTITUTION:When the front and the rear wheels are both in the locking tendency, the braking pressures of the brake cylinders for the front and rear wheels are reduced. Because the capacity of the rear wheel brake cylinder is smaller than that of the front, the rear wheel braking pressure is reduced faster than the front. As a result, the liquid pressure in a chamber 102 reduces faster than that in another chamber 101. This produces a liquid pressure difference between the chambers 101 and 102, so that a pressure receiving piston 74 and a valve spool 68 move to the left to shut a passage 32 from another 34 and also shut the passage 32 from a one 46. Thus the valve spool 68 is operated with the differential pressure between the brake cylinders for the front and the rear wheels to lead to enhancement of the responsiveness.

Title: Optical disk device and control method therefor
Inventor: SAKURAI TATSUAKI
IPC: G11B7/135
Filed: 1994-02-10
Abstract: PURPOSE:To miniaturize the optical system of a device by forming two laser spots with an interval smaller than a gap formed on a recording track on the same track. CONSTITUTION:A system control part 45 seeks a target track with a seek system control part 38 and sets a semiconductor laser element 2b in an operating state at the time of reproducing data. In this state, when a following laser spot SSb is positioned at the head of a header area HDA of a sector, the reproducing signal of the HDA is presented on a reproducing signal RF from this point of time and reproducing signals in a lump are outputted continuously during a time when the SSb is moved to the final part of the HDA. Then, a data recording operation with an SSa can be performed after the HDA is detected by the SSb by setting interval between a preceding laser spot SSa and the SSb to be smaller than the length of a gap GPb. Thus, since a high frequency superposing means is unnecessitated in the driving means of a semiconductor 2a generating the SSa, the device can be miniaturized.
