Title: Bit error ratio measuring device for digital communication system
Inventor: KIZU MASAFUMI
IPC: H04L1/00
Filed: 1991-07-26
Abstract: PURPOSE:To speedily measure a bit error ratio by eliminating time for newly fetching a pseudo random pattern in a case out of synchronization at a digital communication system. CONSTITUTION:Pseudo random pattern data inputted through a system to be measured are read by first and second pattern generators 30 and 32 for comparison. A first changeover SW 30a is connected to the side of a contact A, and a second changeover SW 32a is connected to the side of a contact C. A system changeover SW 34 is connected to the side of a contact E and inputted to an EX-OR gate 16 for comparison, and the data are compared. When synchronism is obtained, the first changeover SW 30a is switched to the side of a contact B and the bit error ratio is measured. In the case out of synchronism, the first changeover SW 30a is switched to the side of the contact A, the system changeover SW 34 is switched to the side of a contact F, and synchronism is obtained again by using the pseudo pattern data read in the second pattern generator 32 for comparison.

Abstract: PROBLEM TO BE SOLVED: To stably feed sheets regardless of their sizes, thicknesses, and conditions by driving and controlling both a belt deformation means that deforms a sheet feed passage consisting of an endless belt and a ventilation means in accordance with the characteristic of the sheet used. SOLUTION: When an input means or a detection means detects that the length of a sheet used, as measured in its feed direction, is of a small size compared with the distance L0 between a separating part T and a fixing part F and the sheet is thin, or when an image mode is for double side and on the second side even if the sheet is thick, a belt deformation means 20e is driven, and a ventilation means 20f is further driven; i.e., an abutting roller is raised upward as it is driven by a solenoid, and a feed belt 20d is held projected slightly above a straight line connecting the separating part T with the fixing part F and deforms the sheet. The ventilation means 20f feeds an appropriate amount of air in the direction along which the sheet is pressed against the feed belt 20d.  Thus the sheet is surely fed to a fixing device 18 with a sufficient feeding force provided by the feed belt 20d.

Abstract: PROBLEM TO BE SOLVED: To improve an S/N and to surely detect a signal by dividing reflected light to prescribed light areas, obtaining a difference between signals obtained from respective areas and reproducing an information signal. SOLUTION: The reflected light A containing zero-order light 20b and 1st- order light from an optical disk 7 are divided to a first light area A1 and a second light area A2 to be detected by a photodetector 21. Then, a light quantity difference between the luminous flux of the first light area A1 consisting of an overlapping area between the zero-order light 20a and the 1st-order light 20b in the track direction T mainly in a peripheral part and the luminous flux of the second light area A2 mainly consisting of the zero-order light 20a hardly containing the 1st-order light 20b in a central part is obtained, and the information signal is reproduced. Thus, the total light receiving amount of the signal is reduced, and on the other hand, the information signal is reproduced without reducing the signal amplitude of the signal detected answering to the shortest pit particularly.  Thus, noises of such as a laser light source 1, the phonodetector 21 and the disk, etc., incorporated in the reflected light A are reduced, and the S/N is improved.

Thus by providing the P<+> layer 2 the punch-through hardly occurs and flat saturation characteristics without a triode characteristics region can be obtained. Moreover the possibility of injecting hot carriers into the gate film can be minimized.

Title: Bearing/electric signal converter
Inventor: NOMURA MINORU
IPC: G01C17/32
Filed: 1986-08-12
Abstract: PURPOSE:To obtain an easy-to-handle bearing-to-electric-signal converter with excellent sensitivity and directivity by mounting bar-shaped ferromagnetic bodies to which means for correcting the unbalanced output of a Hall element and demagnetizing a remanent magnetism is added to the magnetism detecting surfaces of the Hall element. CONSTITUTION:Bar-shaped ferromagnetic bodies 2 made of such a material as ferrite are fixedly attached to both magnetism detecting surfaces of a Hall element 1 perpendicularly to the magnetism detecting surfaces. A coil 3 for generating a prescribed magnetic field for canceling the unbalanced output of the element 1 and the coil 3 for letting a dampedly oscillating current for demagnetizing an unnecessary magnetism in the ferromagnetic bodies 2 flow are wound around them. A connection is performed such that the bearing-to-electric-signal converted output of the element 1 takes a maximum (or minimum) value when a magnetic field detecting direction is directed to a magnetic pole N (or S). Thus, a bearing can be known from a relationship between the magnetic field detecting direction relative to the direction of the terrestrial earth magnetism and the output of the element 1. When a strong magnetism is received from outside, a remanent magnetism lets DC current and damping oscillation current flow 4 in the coil 3 to cancel the strong magnetism. Accordingly, the bearing can be converted to electric signals with a high accuracy.

Title: Frequency tuning circuit
Inventor: HAMADA YOSHIO
IPC: H03J5/02
Filed: 1983-10-05
Abstract: PURPOSE:To improve the frequency tuning accuracy by controlling an output frequency of a frequency synthesizer according to an oscillated frequency of a fixed oscillator. CONSTITUTION:The frequency synthesizer SYN2 consists of a PLL circuit comprising a VCO2a, a loop filter 2b, a phase comparator 2c, a reference frequency oscillator 2d, a frequency converter 2e and a variable frequency divider 2f. An input signal of frequency fR is mixed (3) with a frequency fL1 of the SYN2 by a frequency converter 3, converted into a frequency fIF1 and becomes fIF1=fL1- fR through a BPF4. The frequency becomes fL1=fL2+Nf1 and fIF1=fL2+Nf1- fR, where N is a frequency dividing ratio of frequency divider 2f and f1, fL2 are oscillating frequencies of the oscillator 2d and the fixed oscillator 6 respectively. The fIF1 is mixed with an output signal of the oscillator 6 by the frequency converter 5, converted into the fIP2 and becomes fIF2=fL2-fIF1=fR-Nf1. The frequency tuning is attained by changing the value of the frequency dividing ratio N in response to the input signal frequency fR and the output stability of an output signal is not affected by the frequency fluctuation of the oscillator 6.

Title: Apparatus for monitoring flowing of fluid medium in fluid space
Inventor: ERUNSUTOODEIITERU PURASU
IPC: G01P13/00
Filed: 1991-07-02
Abstract: PURPOSE: To attain large piston stroke assurance at a low flow velocity by disposing a device which functions effectively so as to discharge an excessive amount of medium to an inlet chamber when a piston slides to the first switching position. CONSTITUTION: Oil, after a pump is connected and a magnet value is opened, is sucked through a stand pipe and pressed into respective pipelines. When oil pressure in the pipeline is sufficiently high, a valve 22 is opened, therefore, oil pressure in an inlet chamber 28 increases. As a result, a piston 32 is lifted so as to maintain its shape against gravity or the force of a spring 43. Leakage of oil from a compensation passage 46 is inhibited by designing the whole cross- sectional surface of the passage 46 so as to be smaller than that laded by oil in the piston 32. This is the same as for a ring gap generated between a guide part 32a and a guide 31.
