Title: Curve detector for unmanned carrier
Inventor: MIYATA TAKEHIRO
IPC: G05D1/02
Filed: 1985-05-02
Abstract: PURPOSE:To improve the steering performance by amplifying differentially the detection signal obtained by a pickup coil and delivering the signal to decelerate a driving motor or change the gain of a drive circuit for driving motor when the output exceeds the reference threshold value. CONSTITUTION:A carrier body 4 detects a magnetic field 3 generated by a guide wire 2 via pickup coils 5L and 5R. When these coils 5L and 5R are shifted to one side from the wire 2, the voltage of one of both coils more distant away from the wire 2 is set at a low level. Then it is decided that the carrier 4 enters a curve area when the deviation value exceeds the threshold value that is decided by a setting resistance 7b of an arithmetic circuit 7 for deviation of the carrier body. Based on this decision, the circuit 7 decelerates the right and left driving motors 10R and 10L or changes the gain of a drive circuit for driving motor. Thus the deviation produced when the carrier 4 enters a curve area can be reduced with high responsiveness. This improves the steering performance of the carrier 4.

Title: Collecting/distributing system for signal
Inventor: ISHIKAWA TAKASHI
IPC: H04Q9/00
Filed: 1979-07-26
Abstract: PURPOSE:To ensure the fixing of the terminal storing position of each signal to each unit by securing the shift connection within the unit for the wiring among the connecting circuits, at the same time reducing both the working quantity of wiring and the working cost. CONSTITUTION:The intra-unit wirings between entrance connectors CN0A- CN2A and exit connectors CN0B-CN2B are provided obliquely so that each of unit B0-B2 can take in the signals used for the units at terminal position 3 of entrance connector CN0A and others. With the wiring set obliquely, no correspondence is given among the terminal positions to cause a shift. Thus so-called shift connection is secured. As a result, it is enough for inter-unit cables LL1 and LL2 to form the finserting mouth in such way that the same cables as connecting cable LL0 to signal source SG may be connected successively at the terminal positions of corresponding connectors. Thus the wiring work is easy enough even for an inexperienced worker in the connecting work in the field of construction.

Title: Manufacture of anode base and of fluorescent character display tube
Inventor: KATAOKA FUMIAKI
IPC: H01J31/15
Filed: 1995-04-20
Abstract: PURPOSE: To reduce the adverse effects of a cathode on emission due to decomposition of a phosphor by forming an alkaline earth sulfide phosphor layer over the anode base of a fluorescent character display tube without causing adverse effects such as surface degradation. CONSTITUTION: An anode base for fluorescent character display tube is manufactured. A paste in which 1.5 parts by weight of terepionel and 1 part by weight of CaS:Ce are mixed is applied onto the anode base using a doctor blade. The anode base is baked in nitrogen gas at temperatures not higher than the boiling point of terepionel to form a phosphor layer. The residual emission rate of a fluorescent character display tube using the anode base is good compared with two other examples, one using screen printing and the other using atmospheric baking. The possibility of the surfaces of phosphor particles degrading due to heat treatments in the atmosphere and moisture is totally eliminated, and the fluorescent character display tube having an alkaline earth metal sulfide phosphor that has little adverse affect on emission can be put to practical use.

IPC: G01R19/165
Filed: 1997-04-14
Abstract: PROBLEM TO BE SOLVED: To decrease the number of circuit elements and dissipation power by judging whether an input voltage is equal to two threshold voltages or not and outputting a reset signal when the voltage is lower than the lower threshold voltage or higher than the higher threshold voltage. SOLUTION: In this voltage detecting circuit, a linear voltage circuit 100 outputs a voltage Vl , which is linearly proportional to an input voltage Vext to be detected. In this case, when the input voltage Vext is lower than an input voltage Vext 1 or higher than an input voltage Vext 2, a nonlinear voltage circuit 200 outputs a voltage Vnl lower than the voltage Vl . Furthermore, in the case of input voltage Vext 1<Vext 2, the voltage Vnl higher than the voltage Vl is outputted. Then, a voltage detecting and judging circuit 300 judges the magnitudes of the voltage Vl and Vnl . When the voltage Vl is larger than the voltage Vnl , the reset signal (1) is outputted. Thus, the erroneous operation of a microcomputer can be prevented by decreasing the number of the circuit elements and the dissipation power.

Filed: 1981-06-22
Abstract: PURPOSE:To shorten offset processing time in such a way that, when moving distance of the wire electrode is made shorter or longer than the actual one in keeping with non-parallelism of the working end face and the wire electrode, an offset value is automatically decided by adding and/or subtracting correction values. CONSTITUTION:In case where a work 1 and a wire electrode 2 become short- circuit condition, input power v0 in a limit circuit 11 will be 0V, and its output voltage v1 will be 0V. And the condition of the work 1 and the wire electrode 2 is recognized if it is contact or non-contact by means of having these values given as input to a computer part 7. When roughness on the machining face of the work 1 is large, or the wire electrode 2 ovepasses the working end face, further it is bent and moved to the left, and the moving distance of the wire electrode 2 is made shorter or larger than the actual one, the determined compensating value K is adjusted in its moving distance, so that it can be made into a value equivalent to the normal moving distance between the machining end faces, and offset values are computed. On the basis of these values, offset processing is done for automatically forming into the desired machining shape.
