Title: Radio data communication terminal
Inventor: MARUYAMA SHUSUKE
IPC: H04L27/00
Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To shorten a preamble period and arithmetic processing time by detecting a frequency offset value and estimating transmission line characteristics by using the same preamble signal at the time of obtaining the frequency offset value and the transmission line characteristics in the preamble period, operating a phase rotation means and equalizing reception signals. SOLUTION: A/D converters 11 and 12 ADD-convert the reception signals I and Q, a memory part 13 fetches them for an optional period and controls output and a phase rotation part 14 performs rotation by a required phase portion. By an average phase difference obtained by an average value detection circuit 16 from a phase difference detected by a phase difference detection circuit 15, an integration circuit 17 and a vector transformation circuit 18 rotate the phase of the phase rotation part 14. From the transmission line characteristics during the preamble period obtained by using the signals after the phase is rotated in the phase rotation part 14 by a transmission line characteristic estimation part 19, a tap coefficient setting part 20 sets the tap coefficient of an equalizer 21.  Thus, the equalizer 21 equalizes and demodulates the output of the phase rotation part 14 and the preamble period is shortened.

Title: Charger
Inventor: YAMAZAKI YASUHARU
IPC: H02J7/02
Filed: 1993-04-15
Abstract: PURPOSE:To provide a charger which can load at least two batteries and in which an optimal charging current can be set without requiring large power supply capacity when more than one battery is subjected to supplementary charging or trickle charging. CONSTITUTION:Charging sections 9, 10 can be set with a boosting charge current of 1100mA, for example, and a standard charging current of 60mA, for example. When the supplementary charging of a battery 21 in a battery pack 15 is conducted simultaneously with the charging of a battery 23 in a battery pack 16, or when the trickle charging of the battery 21 in the battery pack 15 is conducted simultaneously with the trickle charging of the battery 23 in the battery pack 16, the standard charging current is set in order to prevent the current capacity of an AC/DC circuit 2 from increasing excessively. When trickle charging is conducted with the standard charging current, the current supply time is prolonged thus conducting the charging similar to trickle charging with boosting charge current.

Title: Magnetic bubble driver
Inventor: TAKAHASHI TSUNESUKE
IPC: G11C19/08
Filed: 1978-09-12
Abstract: PURPOSE: To equalize nearly the building-up time of a triangular-wave signal flowing through an excitation coil for revolving magnetic field generation to its downward time by driving the excitation coil through several switches controlled by pulses which rise at the same time and fall differentially.  
     CONSTITUTION: Switches S 11  and S 12 , and S 21  and S 22  are controlled by pulses 51 and 52 which rise simultaneously and differing in width and similar pulses 53 and 54 which differ in period by one quarter. With switches S 11  and S 12  both ON, a positive-polarity current, flowing to excitation coil L for revolving magnetic field generation for magnetic bubble control, rises and switch 11 only OFF, the coil current falls by flowing to switch S 22 . With switches S 11  and S 22  OFF, the coil current is discharged through diodes D 12  and D 21 . This discharge is reduced in time constant by a diode in an ON state and the rise curve of the triangular wave bends to flow the triangular-wave current with the rise period nearly equal to the fall period through coil L, thereby driving a bubble control coil with neither lowering of drive efficiency nor amplitude unevenness.

Title: Molecular-beam source crucible for molecular-beam epitaxy
Inventor: KAWADA ATSUO
IPC: C30B23/08
Filed: 1992-04-06
Abstract: PURPOSE: To enable an increase in frequency of possible film formation and a reduction in process time due to no overflow of a melt from a crucible without reducing the amount of a charged raw material or decreasing the heating rate by finishing the inside surface of the crucible into a mirror surface and thereby suppressing the entry of the melt into the crucible. CONSTITUTION: This molecular-beam source crucible for molecular-beam epitaxy may be obtained by usually carrying out the mirror surface finish to the surface roughness of Rmax <=2μm. The material of the crucible is preferably made of a pyrolytic boron nitride from the viewpoint of purity, heat resistance and strength. For example, the crucible is produced by reacting a mixed gas of ammonia with boron trichloride at 1900 deg.C under <=10Torr pressure, then depositing the resultant product in a mold made of graphite, taking out the deposited product from the mold and removing the graphite sticking to the inner surface by air oxidation. The mirror surface finish may be performed by polishing treatment with abrasive grains.  The crucible thus produced can be used as a molecular beam source crucible for the molecular-beam epitaxy by attaching a heater, a reflector and a thermocouple thereto.

Abstract: PURPOSE:To realize high integration density of IMOSIC by providing N channel and P channel MOS elements on the same Si substrate and particly siliciding the junction part of both gates using N type and P type poly-Si for respective gates. CONSTITUTION:The N<+> source drain 49n, poly-Si N layer 43m and P source drain 43p and poly-Si P layer 43p are sequentially and selectively formed by forming a field oxide film 47, channel cuts 50p, 50n and auer 42 on an N type Si substrate 41, while a poly-Si gate on a gate oxide film 47a.

PtSi 48 is thereby formed and Pt is on the ilm 48 is removed by the aqua regia. Thereafter, the surface is covered with an Al electrode 52 and then with a PSG52. When a P type poly-Si gate is used for a P channel FET, surface impurity concentration increases rather than that of the N type poly-Si. Thereby, a withstand voltage of a punchthrough becomes high, a threshold voltage can be reduced and FET can be super-miniaturized by reducing a gate width. Moreover, a number of connecting holes can be reduced by connecting the N type poly-Si gate and PtSi and a CMOS having high integration density and high reliability can be obtained.

Filed: 1994-05-27
Abstract: PURPOSE:To prevent vibration and deformation of a plate material which are generated due to fluctuation of tensile force of the plate material by controlling rotational drive torque by a sum of tensile force compensation amount obtained by calculating inertia value due to the weight of the plate material and a speed control signal. CONSTITUTION:A difference between target speed from a target speed operation circuit 12 and conveyance speed of a plate material 1 which is detected by a speed detector 10 is calculated by an adder 16, and speed compensation amount torque for reducing the difference down to zero is calculated by a speed control circuit 11. A tensile force compensation amount operation circuit 15 calculates inertia due to the weight of the plate material 1 through which an upper-step roll 4 driven by a drive device 9 passes by winding, and calculates torque to be compensated for the drive device 9, namely, tensile force compensation amount torque, based on the inertia amount. An adder 13 adds the tensile force compensation amount torque to the speed compensation amount torque to send the sum to a torque control circuit 14. The torque control circuit 14 controls the drive device 9 based on the sum of both compensation amount torque so that tensile force of the plate material 1 becomes a predetermined value.

Filed: 1992-05-06
Abstract: PURPOSE:To provide a reference light type Doppler speedometer in which speed detection error due to intensity modulation, which takes place when the laser beam is subjected to frequency shift through a frequency shifter, is suppressed. CONSTITUTION:Laser beam emitted from a laser light source 1 is split, at first, through a beam splitter 9 into two beams and the laser beam, subjected to frequency shift through a frequency shifter 4, passes through a beam splitter 10 and a lens 11 to produce a laser beam 3 for irradiating an object 2 to be measured. The laser beam 3 is scattered on the surface of the object 2 and a part of scattered light is collected through the lens 11 and then reflected on the beam splitter 10 to produce a signal light 12. The signal light 12 passes through a mirror 13 and a beam splitter 14 and arrives at an optical detector 8 but since the quantity of light is reduced significantly as compared with the irradiating laser beam 3, noise having relatively lowered frequency DELTAf does not reach the detection limit of the optical detector 8 and not detected.
