Title: Steering control circuit for unmanned carriage
Inventor: TAYAMA HARUO
IPC: B60L15/20
Filed: 1987-04-30
Abstract: PURPOSE:To perform automatic steering operation stably by providing a gain controller and holding a steering gain constant even if the field magnetic current of a motor varies. CONSTITUTION:A steering detection signal from a steering sensor 1 is amplified 2 and applied to the armature 61 of one driving motor by a summing amplifier 41 together with a traveling speed command value from a traveling speed setter 3. Further, a subtracting amplifier 42 subtracts the steering signal from the traveling speed command value and applies the difference to the armature 62 of the other driving motor. Further, current detectors 51 and 52 detect two armature currents, whose mean value is calculated by an averaging amplifier 7 and applied to field magnetism elements 81 and 82. In this case, a field magnetic current detector 92 which generates a function of the correspondence of a driving motor gain to the field magnetic current, and a gain controller 93 which adjusts the gain of the steering signal with those signals are added in a steering control circuit. Then the steering gain is held constant irrelevantly to variation in field magnetic current to stabilize steering control.

Title: Thin film and method of fabricating the same
Inventor: TANAKA TSUNEO
IPC: C30B29/48
Filed: 1978-08-30
Abstract: PURPOSE: To obtain a thin film having more V(IV) group elements than stoichiometric amount as compared with suitable ratio of the number of V(VI) group elements to that of III(IV) group elements flying over the substrate at the temperature of the substrate in vacuum higher than 1.  
     CONSTITUTION: When Ga and As are simultaneously supplied on a substrate, the adhering coefficient of the As largely depends upon the molecular beam intensity ratio of Ga to As on the substrate and the substrate temperature to grow excessive As film more than stoichiometric amount. When two or more element molecules are simultaneously flied over the substrate in vacuum in a mnaane that the adhering coefficient of one X of the elements is solely smaller than but that Y of other element is simultaneously flied over the substrate so that the ratio of X to Y in flied amount to the substrate temperature is certain value, whereupon the adhering coefficient of X is altered. When X is supplied in larger amount than Y, the thin film can be grown including excessive X more than the stoichiometric amount. This thin film can be thermally treated for crystallization and forming porous substance.

Title: Synchronizing signal detection circuit
Inventor: MORITA KAZUO
IPC: H04W88/02
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To avoid discrimination of a synchronizing signal pattern for a period other than a synchronizing signal period even when a bit error is caused in reception data. SOLUTION: A bit comparison section 2 compares reception data D1 received serially and a synchronizing signal pattern D2 generated by a synchronizing signal pattern generating section 1 for each bit to provide an output of a comparison result. A mismatching bit number count section 3 counts the bit number mismatched by the bit comparison in the unit of synchronizing signal patterns. A mismatching bit number comparison section 4 reads number of preceding mismatched bits (k) stored in a bit number storage section 5 and compares it with a mismatched bit number (m) received newly and provides an output of a control pulse P1 when a new mismatched bit number (m) is smaller, and updates the stored value (k) in the bit number storage section 5 with the mismatched bit number (m).  A synchronizing timing signal generating section 6 generates a synchronizing timing signal while changing the leading time in response to the control pulse P1.

Title: Fault-point ranging unit for power cable
Inventor: MITSUI TSUTOMU
IPC: G01R31/08
Filed: 1978-09-04
Abstract: PURPOSE:To attain ranging to an insulation-breakdown fault point of a power cable at any time by eliminating dead time, by providing high-frequency filter, where a frequency component of more than a specific frequency is allowed to pass, to both the ends of the power cable. CONSTITUTION:A surge is detected by current transformers provided to both ends of power cable 1. When the output voltage of high-frequency filter 3 which allows  a component of this surge higher than a frequency value expressed by formula I to pass is higher than a noise level, pulse generator 4 connected to this high- frequency filter 3 generates a pulse. A pulse generated by pulse generator 4 at terminal B is transmitted to hour meter 5 at terminal A via cable 10, and a pulse generated at terminal A is also transmitted to hour meter 5. Hour meter 5 calculates arrival time difference (tA-tB) between pulses transmitted from terminals A and B, so that ranging to a fault point will be performed according to the difference. Consequently, ranging to the insulation-breakdown fault point of a cable is done at any time without dead time.

Filed: 1982-06-25
Abstract: PURPOSE:To efficiently dispose difficultly biodegradative substance, in the method of treating waste water in a reaction tank using H2O2 and a ferrous salt, by separating formed sludge and returning it to the reaction tank. CONSTITUTION:Raw water containing difficulty biodegradative substance, e.g. humic acid, is introduced into a reaction tank 1. Sludge is returned to said reaction tank 1 from a precipitation tank 2, and Fe<2+> is formed by the reaction of Fe(OH)3 in the sludge with added H2O2 to oxidatively decompose organic substance in the raw water. FeSO4 is separately supplemented to the reaction tank 1, so that its action together with H2O2 contributes to the oxidative decomposition of the organic substance. The raw water is then adjusted to a pH of about 5 by adding NaOH to it in a pH-adjusting tank 3. Hence, Fe(OH)3 acts as a flocculant and forms flocks with humic acid, etc. in a flocculating tank 4. Said flocks are separated as sludge in a precipitation tank 2, and partially returned to the reaction tank 1. A supernatant liquid is drained.
