Title: Start-stop synchronizing type serial data receiving circuit
Inventor: KITAMURA FUMIHIDE
IPC: H04L7/04
Filed: 1988-03-10
Abstract: PURPOSE:To minimize read errors by equipping the title device with a means for changing the phase of a sampling pulse coupled to another means to generated the sampling pulse. CONSTITUTION:When a start bit 102 in received serial data 101 is detected, an internal reference clock signal 104 is counted for a number previously inputted from the phase input part of the sampling pulse. After a first data bit detected time 112 is obtained, a sampling pulse 110 is generated synchronously with the internal reference clock signal 104, and a first data bit 103 is sampled during sampling time 108. Thus, since the phase of the sampling pulse 110 can be adjusted, the data bit 103 can be sampled at a point where the waveform of the data bit 103 is the most stable when waveform distortion occurs in the data bit 103 of the serial data 101 generated by the electric characteristics of a serial data transferring line, and the read errors can be prevented.

Title: Method for improving inductance of coil using fe based amorphous alloy
Inventor: FUJIKURA MASAHIRO
IPC: H01F1/153
Filed: 1993-03-17
Abstract: PURPOSE:To improve magnetic characteristics after heat treatment of a coil using a Fe group amorphous alloy by impressing a DC or AC magnetic field of a specific value or more after a core of a Fe based amorphous alloy of specified composition is heat-treated. CONSTITUTION:A Fe based amorphous alloy with the composition of Fea, Sib, Bc, Cd is used as a core to impress a DC or AC 80A/m or more magnetic field on the core after its heat treatment, where a, b, c, d represent atomic percent making the following relation: a=100-b-c-d, 1<=b<=20, 5<=c<=20, 0<=d<=5. Impressing a magnetic field after heat treatment on a magnetic core prepared from this Fe group amorphous alloy strip causes inductance to increase. Therefore, a strict administration of heat treatment is unnecessary.

IPC: H04B10/00
Filed: 1981-04-16
Abstract: PURPOSE:To increase the number of communication devices which can be connected in multi-drop connection without lowering the capacity of the driver of the communication devices, by connecting plural transmission lines each other with a repeater without any malfunction. CONSTITUTION:Plural communication devices 1A-1N and 2A-2M are connected  respectively to transmission lines 3 and 4 in parallel, and a repeater device 8  connects the transmission lines 3 and 4. A signal from the transmission line 3 is  received by the 1st receiver 23 of the device 8, and the signal is transmitted to  the transmission line 4 through the 1st driver 24 after the signal is shaped in  waveform and amplified. In the same way, a signal from the transmission line 4  is received by the 2nd receiver and transmitted to the transmission line 3  through the 2nd driver 26. When each of receives 23 and 25 obtains outputs, an  operation stop signal is supplied to the receiver 25 and the driver 26 or the receiver 23 and the driver 24 from the 1st and 2nd reception switching circuits 21 and 22, and thus, the number of communication devices which can be connected,  is increased without lowering the capacity of the drivers 24 and 26.

Title: Measuring instrument
Inventor: TSURUNO SHINICHIRO
IPC: G01B11/02
Filed: 1999-03-04
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of measurement errors by eliminating the variation of the relative position between a head amplifier and a camera by installing a supporting plate to a mover so that the plate may not come into contact with a gate type frame and attaching the head amplifier to the supporting plate. SOLUTION: When a gate-type frame 4 is driven in the Y-axis direction (the longitudinal direction of guide rails 2), a strong driving force acts on the central part of the lower side 42 of the frame 4 through a nut holder 44 and the central part makes elastic deformation. When the central part is elastically deformed, the relative position between a CCD camera 51 attached to the upper side 41 of the frame 4 and a mover 3 does not change, because both end sections of the lower side 42 with which the mover 3 comes into contact are not deformed. Therefore, the relative position between a supporting plate 6 installed to the mover 3 in such a way that the plate 6 does not come into contact with the frame 4 and the camera 51 does not change.  In addition, since no external force acts on the supporting plate 6 and the plate 6 is not deformed, the relative position between a head amplifier 71 attached to the plate 6 and the camera 51 also does not change.

Title: Repeater
Inventor: KOMAKI TSUNEMATSU
IPC: H04B3/36
Filed: 1984-03-27
Abstract: PURPOSE:To attain the signal amplification in a semidouble communication mode without using any special control signal line, control data, etc., by inhibiting the output of an amplifier which is opposite in the direction, if a carrier signal at one side is detected. CONSTITUTION:A carrier signal sent from a communication medium 5b is amplified by an amplifier C13 and supplied to a carrier detecting part b15. Then a carrier-detected output signal 21 is outputted through the part b15. The output of an amplifier D14 is permitted by the signal 21 and at the same time the output of an amplifier A10 is inhibited. As a result, the carrier signal if outputted later from a communication medium 5a is not sent to a stage further than the amplifier A10 of a repeater 3, and therefore not to the side of the medium 5b. The same way of control is executed even in an adverse case.

Title: Epitaxial growth of compound semiconductor
Inventor: MISAKI TOSHIYUKI
IPC: H01L21/205
Filed: 1986-03-14
Abstract: PURPOSE:To increase the evenness of film thickness inside a wafer surface by a method wherein the wafer is epitaxially grown using group III organic metal as source gas as well as carrier gas comprising hydrogen and argon. CONSTITUTION:When e.g. 20l/min of carrier hydrogen, 15cc/min of arsine and 1.5cc/min of TMG from a gas leading-in port 1 to grow a GaAs epitaxial layer at 620 deg.C, the film thickness in the gas flowing direction is made thick inside if carrier gas is hydrogen only since gas (TMG) of group III element is almost consumed inside the gas leading-in port 1 not to be carried to outside. On the other hand, if a few % of argon is led in as carrier gas, the gas of group III element is consumed inside to make the overall film thickness even and if high % of argon is led in, the gas film is made thick outside reverse to the case of hydrogen. Resultantly, the evenness of film thickness of GaAs epitaxial layer can be increased by using hydrogen exceeding 90% and argon not exceeding 10% instead of hydrogen, a single substance, as carrier gas.

Abstract: PROBLEM TO BE SOLVED: To prevent gouging from being formed and to obtain a target machined shape with high precision by evaluating two-dimensional image data according to specific standards and generating a tool movement path for machining on a base curved surface group according to the evaluation result and the tool for machining. SOLUTION: On a three-dimensional base curved surface group, two-dimensional image data are arranged and the positional relation between the base curved surface group and the two-dimensional image data is determined.

On a lattice segment group 91 formed by connecting the offset vertexes, a tool path pattern line group is projected and a group of intersections 100 of the lattice segments and tool line patterns is connected according to tool path pattern standards to generate a machining tool movement path 101.
