Title: Nonlinear compensating circuit
Inventor: OKU MASUO
IPC: G11B7/00
Filed: 1981-11-04
Abstract: PURPOSE:To stabilize the operation with a high S/N for a nonlinear compensating circuit, by eliminating the cross modulation component out of the multiplex signals by means of a signal obtained by multiplying the carrier component of high frequency signals forming the multiplex signals by a low frequency signal with a prescribed relation between the amplitude and the phase. CONSTITUTION:A multiplex signal shows a video FM signal with a fed 10 frequency, a sound FM signal with the amplitude respectively. Such multiplex signal is set at a prescribed level at a level control circuit 13 by a control signal supplied through an input terminal 12. The sound FM signals separated through a filter 14 are supplied to a multiplying circuit 17. At the same time, the carrier component of the video FM signal is separated from the multiplex signal through a filter 15. This carrier component receives a phase shift 16 of pi/2 radian of the carrier wave and is supplied to the circuit 17. Then the output signal of multiplication of the video FM carrier wave and the sound FM signal is supplied to an adder circuit 18. Thus the cross modulation in the multiplex signal supplied from an input terminal 10 is offset and delivered 11.

Title: Constraint effectiveness check
Inventor: HARDIN RONALD H
IPC: G06F17/50
Filed: 1999-06-23
Abstract: PROBLEM TO BE SOLVED: To check the effectiveness of constraint to be used especially for the check of a type in respect to a test for system design. SOLUTION: When a constraint set allocates non-coincident values in a prescribed state of system model state space, a check tool 51 deals with the prescribed state or a state group as a so-called restoration disabled state. Namely the tool 51 does not approve all routes from the prescribed state or state group to the set of a reset state. Consequently the tool 51 can judge mutual contradiction or over constraint by analyzing only constraint to which a function is applied in the restoration disabled state instead of the analysis of values defined by all constraint inputs to the tool 51.

Title: Manufacture of semiconductor laser
Inventor: WAKAO KIYOHIDE
IPC: H01S5/11
Filed: 1985-08-09
Abstract: PURPOSE:To form different diffraction gratings with the same phase relation on one substrate by a method wherein, after a thin film of compound containing InP is formed in a region of an InP substrate where the first diffraction grating is to be formed, a resist film is formed over the whole surface. CONSTITUTION:After an InGaAsP layer 22 is formed on the surface of an InP substrate 21, the InGaAsP layer 22 is removed by etching except the part on a region where the first diffraction grating is to be formed. Then a resist film 23 is formed over the whole surface and the pattern of the diffraction grating is formed by a double-beam interference method. If etching is carried out with sodium hydroxide after exposure, only the InGaAsP layer is etched. Then, if etching is carried out with a solution of hydrochloric acid, where the InGaAsP layer remains, this layer serves as a mask and prevents the substrate from being etched and, on the other hand, where the InGaAsP layer is not left, only the resist serves as a mask and the substrate is etched. As a result, two different etched shapes are formed on the substrate so that the first diffraction grating 24 and the second diffraction grating 25 can be obtained. Then, the resist film and the InGaAsP layer are removed.

Filed: 1981-11-04
Abstract: PURPOSE:To reduce the number of solenoid valves to one and to vary the reincreasing characteristic of liquid pressure when the same is recovered by replacement of a spring, by interlocking a valve mechanism with a reservoir piston, said valve mechanism being interposed between a master cylinder and a wheel cylinder. CONSTITUTION:A master cylinder is connected to a port 15, to which a wheel cylinder is connected. A valve body 12a and a valve seat 9a of a balance piston 12 constitute a valve mechanism, cutting off the communication of both the pistons. A solenoid valve 21 is opened in response to a slide signal to discharge  a pressurized liquid in the wheel cylinder into a liquid chamber (c). Said pressurized liquid forces a reservoir piston 11 right and then forces the balance piston 12 right, to close the valve. A hydraulic pump 26 pressurizes a liquid in the reservoir prior to feeding back into the wheel cylinder. In such structure, the solenoid valve may be required by one and the reincreasing characteristic of the liquid pressure may be varied.
