Abstract: PURPOSE: To increase the crystalline property for the low fusing-point semiconductor thin film such as InSb, GaSb, Ga x In 1-t Sb or the like by giving the zone melting to the semiconductor thin film formed on the substrate in the inactive gas higher than the atmospheric pressure by 0.1kg/cm 2 .  
     CONSTITUTION: SiO 2  layer 12 is coated on the surface of Ni-Zn ferrite substrate 11 which is mirror-polished; Hall device type groove 17 is drilled through fit-etching; and the entire surface is convered with glass 13 to be used as the foundation of InSb. Then InSb layer 14 and In layer 15 are laminated on glass 13 with coating to then receive the zone melting in the Ar gas higher than the atmosperic pressure by 0.1kg/cm 2 . After this, the lines caused on the surface and In 2 O 3  layer 16 are polished away, and furthermore other layer 14 is polished away so that layer 14 may remain only within groove 17. With formation of the Hall device in such way, the crystalline property is enhanced to increase the S/N.

Title: Signal delay circuit and signal processor using the circuit
Inventor: YOSHINO YOSHINORI
IPC: H03K5/13
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To obtain the comparatively large delay value with high accuracy by turning on and off a switch by means of a clock signal with prescribed pulse width, charging the switch only in its on-time by a constant current to generate the reference voltage, comparing the reference voltage with the voltage charged by an input signal only in the on-time via a comparator, and outputting the signal that is delayed by a time proportional to a time constant. SOLUTION: Relating to a delay circuit part 22, a switch S4 is turned on by an input signal DATAP and the capacity C3 is charged by a constant current source I1. When the C3 exceeds the reference voltage VREF of a reference slice level generation part 21, the output Vout of a comparator CMP is changed to a low level. When the input signals DATAP and DATAN are set at high levels, the switch S4 is turned off and a switch S5 is turned on. Then the electric charge of the capacity C3 is discharged. When the C3 is reduced less than the voltage VREF, the output Vout of the comparator CMP is set at a high level again. Then the delayed signals are repetitively outputted from the CMP.
