Title: Automatic guided vehicle with radar failure diagnosis function
Inventor: KAMINAGA TOMOHARU
IPC: G01S7/40
Filed: 1999-05-13
Abstract: PROBLEM TO BE SOLVED: To accurately decide a failure of a scanning laser radar equipped in an AGV(Automatic Guided Vehicle). SOLUTION: A forward object detecting overlap area is set in object detecting areas 23a, 23b of scanning laser radars 11a, 11b. When one of the scanning laser radars 11a, 11b fails, the failing scanning laser radar 11a or 11b cannot detect an object 26 in the front object detecting overlap area. Accordingly, when outputs of the scanning laser radars 11a, 11b concerning the forward object detecting overlap area don't coincide, it is decided that one of the scanning laser radars 11a, 11b fails.

Abstract: PURPOSE:To attain sure training by confirming the convergence of mutual automatic equalizers by interactive form between opposed MODEMs and restoring the state to a normal transmission state. CONSTITUTION:When a code error rate detector 13 detects a code error rate of a prescribed value or above, a training control circuit 15 enters the training state. Then a 1st pattern giving violation to a ternary class IV P.R code set by a pattern setting circuit 4 is transmitted/received mutually between its own station and an opposite station. When its own station uses the pattern detector 12 to detect the 1st pattern of prescribed number of times or above for a prescribed time, a 2nd pattern giving violation to the ternary class IV P.R code is sent to the opposite station and when its own station detects the 2nd pattern, the 1st and 2nd patterns are sent alternately to the opposite station by N-number of times. When the opposite station detects the repetitive pattern by N-number of times, the state is restored respectively into the multilevel transmission state.

Title: Detection for fault of a-d input circuit
Inventor: SANO KATSUHIKO
IPC: H03M1/10
Filed: 1995-05-31
Abstract: PURPOSE: To realize the fault detection method for A-D input circuit which doesn't extend the circuit scale and improves the fault detection capability for A-D input circuit. CONSTITUTION: Two analog inputs 10 of a multiplexer or the A-D input circuit consisting of the multiplexer 1 having plural analog inputs 10 and an A-D converter 3 of binary code output are connected to a supply voltage Vcc and a ground voltage E, and the multiplexer 1 is switched, and its output is inputted to the A-D converter 3. Since all the bits of the conversion output of the supply voltage Vcc are '1' in this case, bit '0' is detected to detect fixing of bit '0'. Since all the bits of the conversion output of the ground voltage E are '0', bit '1' is detected to detect fixing of bit '1'. Consequently, the precision of fault detection is improved because a fault is detected without extension of the circuit scale independently of the allowable range or the displacement with time of an input signal.

IPC: B29L9/00
Filed: 1986-06-11
Abstract: PURPOSE:To obtain the title core for molding, low in a content of a volatile organic blowing agent and not forming pinholes in an unsaturated polyester layer, by impregnating a specified modified polyolefin resin with a volatile organic blowing agent and expanding the resin by heating in a mold. CONSTITUTION:A modified polyolefin resin is produced by impregnating a polyolefin resin (e.g., high-density polyethylene) with a vinyl monomer (e.g., styrene) and polymerizing the monomer. This modified polyolefin resin is expanded with a volatile organic blowing agent (e.g., propane) to produce pre-expanded particles. These pre-expanded particles are expanded by heating in a mold to produce a foam of a volatile organic blowing agent content <=0.5wt%. This foam is used as a core for molding an unsaturated polyester resin. The volatile organic blowing agent content of this core is so low that no loss of the strength of bond between the core material and the unsaturated polyester resin layer, etc., occurs.

Title: Balanced modulator
Inventor: TANABE KENZOU
IPC: H03B25/00
Filed: 1979-10-16
Abstract: PURPOSE: To reduce the cross modulation distortion and the mutual modulation distortion, by  increasing the bias current to the balanced modulator circuit according to the increase of the input  level of the signal and at the same time reducing the level of the local oscillation signal.   
     CONSTITUTION: The transistors (TR)Q 17 ∼Q 20 , Q 15  and Q 16  plus resistor R 14  form a double  modulator circuit; while the TRs Q 13  and Q 14  form the constant current source to the TRs Q 15   and Q 16 , respectively. The voltage which is applied to the input terminal 23 and varies in a DC  way increases in the positive direction according to the increase of the signal input voltage supplied from the antenna and applied to the input terminal 20. Thus the bias current of the TRs Q 15   and Q 16  increases according to the increase of the signal input voltage. As a result, the input level  increases for the maximum allowable signal. At the same time, the local oscillation injection level  to be injected to the double balanced modulator circuit through the input terminal 19 lowers down  with reduction of the AC impedance of the FETQ 9 . Thus the frequency conversion conductance is  lowered. Thus both the cross modulation distortion and the mutual modulation distortion, which  are caused by the increase of the intermediate frequency signal level at the output terminal 21,  can be reduced.

Title: Film formation of magnetoresistance element
Inventor: TAKASHITA TADAAKI
IPC: H01L43/12
Filed: 1987-06-01
Abstract: PURPOSE:To obtain a magnetoresistance element with a high sensitivity by a method wherein, after a magnetoresistance element pattern and adjacent patterns are formed, conductive metal thin films are applied to the parts to be magnetoresistance elements. CONSTITUTION:A rod-shape resistor pattern 2 and adjoining patterns 3 and 4 which have smaller lengths and larger widths than the resistor pattern 2 and are provided on both sides of the pattern 2 are formed on a nonmagnetic substrate 1 with ferromagnetic thin films in parallel to each other and with certain intervals between each other. Then conductor thin films 5 are applied to the surfaces of the upper and lower part patterns 2'-4' of the parallel patterns 2-4 shown by hatched parts with dot lines L1 and L2 as boundaries while the magnetic thin film patterns with an identical longitudinal length L are exposed. Although the longitudinal length of the resistor pattern 2 is reduces, as magnetic properties only are utilized, forming the conductor thin films 5 on the surface has no influence upon the effect. With this constitution, a demagnetizing field induced in the resistor pattern 2 part can be relieved by the adjacent patterns 3 and 4 over the whole region and the magnetoresistance effect can be enlarged.
