Title: Stop position detector for moving stand in machine tool
Inventor: OZAKI KEIZOU
IPC: B23Q5/52
Filed: 1979-08-31
Abstract: PURPOSE: To improve detecting accuracy with improvement of responsibility to the pressure by detecting the stop position of a moving stand by a pressure switch with use of Bourdon tubes to actuate by pressure difference in the cylinder.  
     CONSTITUTION: When a moving stand moves in the left direction until it hits a stopper 8, oil pressure in a chamber (A) in a cylinder 2 becomes almost zero, then oil pressure in a chamber B goes up, and a big pressure difference is generated in the cylinder 2. This pressure difference rises the tip of a Bourdon tube 48 to the highest positin while it send down the tip of a Bourdon tube 46 to the lowest position, a screw 60 comes into cntact with a displacing member 56 to put a switch 68 ON. The control part receives the ON signal from the switch 68 and gives the signal to a solenoid. Thus, it returns and moves a spool 82 in the right direction, sets a direction change-over valve 10 into the neutral condition, and gives exciting signals to the solenoid of the direction change-over valve for the cylinder to move another moving stand.

Title: Knocking control device for multi-cylinder type internal-combustion engine
Inventor: SUEMATSU TOSHIO
IPC: F02P5/152
Filed: 1982-06-30
Abstract: PURPOSE:To reduce an output loss and improve knocking control during a transition period by a method wherein the valve opening angles for all the cylinders are advanced when knocking occurs and then the number of times of ignition until they are delayed is independently controlled. CONSTITUTION:An igniter 4 for multi-cylinder type internal-combustion engine is controlled by an ignition timing instruction signal which is obtained by a method wherein a fundamental ignition timing calculated by the outputs from an air flow meter 24 and a crank angle sensor 18 in a control circuit 20 is corrected in response to whether the knocking is sensed by the knocking sensor 12 or not. In this case, the control circuit 20 corrects the ignition timing toward spark delay for all the cylinders when the knocking occurs and at the same time the ignition timing is corrected toward spark advanced for each of the cylinders when the knocking is not found. A spark plug for each of the cylinders is controlled in response to said fundamental ignition timing and an ignition timing equivalent to the sum of said delayed spark correction value and the advanced spark correction value.

Title: Manufacture of semiconductor device
Inventor: FUKUMOTO MASANORI
IPC: H01L29/423
Filed: 1983-06-21
Abstract: PURPOSE:To reduce the film thickness of a double layer gate electrode without deteriorating gate insulation withstanding voltage by implanting ions to the surface of a lower-layer poly Si film, laminating another metal such as a high melting-point metal or Al and a metallic silicide film and treating the whole at a high temperature. CONSTITUTION:A field oxide film 2 and a gate oxide film 3 on an N type Si substrate 1 are coated with a poly Si film 4, and P is thermally diffused. The ions of As 5 are implanted to the surface, and an Mo film 6 is evaporated. The films 6 and 4 are removed selectively in succession by using CCl4+O2 and a Freon group mixed gas to form a gate electrode 6, and P type ions are implanted to shape source-drain layers 7. A CVD SiO2 film 8 is formed, and the whole is treated for thirty min at 900 deg.C. Since lattice defects are formed uniformly on the surface of the poly Si film 4, Mo and poly Si mutually diffuse preferentially and equally through the defects, and do not penetrate through the gate oxide film and do not reach to the substrate 1. Openings are bored to the SiO2 films 8, 3, and Al/Si electrodes 9 are attached. According to the constitution, the deterioration of the dielectric strength of the gate oxide film as a foundation is prevented even when poly Si 4 is thin, and the thickness of the electrode can be thinned.

Abstract: PURPOSE:To correctly read out a word character string written by irregular pitches without sharply increasing a character recognizing time by providing the word reading system with a pattern segmenting means, a character pattern rectangle forming means, a character recognizing means or the like. CONSTITUTION:A photoelectric converting means 41 scans an input document and outputs a word character string pattern and the pattern segmenting means 42 extracts the arrangement of a rectangle surrounding each pattern.

Title: Circuit board and its marking method
Inventor: HAKAMAZUKA ATSUSHI
IPC: H05K3/00
Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To simplify marking processing and contract the processing space by forming a marking circuit with heating element on a board body, discoloring a thermosensitive paper set near it by the heat of the heating element for discriminating non-defectives/defectives. SOLUTION: When a circuit board 1 is discriminated as being non-defective on the basis of the inspection by an inspecting device 10, a controller 4 switches a power source circuit 9 from a first wiring 7 (practical wiring) to a second wiring 8 (marking circuit) by a changeover switch 3 and supplies a power source voltage to a heating element 5 to have it heated. Since a thermosensitive paper 6 wound on the heating element 5 and mounted on the circuit forming surface of a board body 2 is discolored by this heat, it can be discriminated that the circuit board 1 is non-defective. However, when the discrimination result is defective, the thermosensitive paper 6 is not discolored since the power source circuit 9 is left as it is, connected to the wiring 7. In this way, the marking processing can be performed automatically, and the set of the marking position is dispensed with.

Title: Ultrasonic flow meter
Inventor: KOUNO MASARU
IPC: G01F1/66
Filed: 1978-09-14
Abstract: PURPOSE: To reliably eliminate the influences from a drift so that the flow rate can be measured in high accuracy by simultaneously measuring the propagation speeds in foward and backward directions with respect to the flow with the use of a plurality of transducers.  
     CONSTITUTION: A measuring circuit 25 measures the differences in the ultrasonic propagation time in the forward and backward directions between transducers TD 21 and 22. While the resultant output voltage VA is being fed to a terminal 29, a measuring circuit 26 measures the differences in the forward and backward ultrasonic propagation time between transducers TD 23 and 24 and feeds its output voltage VB to a terminal 33. The average value between the voltages VA and VB is calculated by an average circuit 34 and is fed out as the flow rate output. As a result, even if the drift component is timely varied, its influences can be eliminated without fail. Incidentally, the periods for which the forward and backward measuring periods are interchanged, are preset at different values for the respective groups of the transducers TD so that the electric and ultrasonic interferences may not be mutually established.

Title: Resistance welding method of foil and wire
Inventor: MAKINO MITSUO
IPC: B23K11/00
Filed: 1978-09-14
Abstract: PURPOSE: To achieve saving of process and improvement of performance by folding a foil once or more and superposing the same, installing the superposed foil part on the electrode side and directly resistance-weld the foil and wire.  
     CONSTITUTION: A foil 2 is bent at a suitable length and the bent foil part 2a is superposed. With this folded foil part 2a being faced to the upper electrode 7, a wire 1 is installed to the lower electrode 8. The foil 2 and wire 1 is resistance-welded while being contacted at the portions inner than the mutual boundary of the foil 2 and wire 1 by a tapered electrode 7 having the end of a width smaller than the folded length of the folded foil part 2a or an electrode of truncated conical shape to obtain a bonded region 6b, and this results in considerably improved bonding strength. If, in this case, a groove 8a matched to the shape of the wire 1 is formed at the end face of the lower electrode 8 and welding is done by installing the wire 1 in this groove 8a, then the range of weldable current increases and the higher bonding strength may be obtained.
