Title: Frequency control system for induction motor of vehicle
Inventor: SHIBAMOTO MASAHIKO
IPC: B60L9/16
Filed: 1980-01-25
Abstract: PURPOSE: To control and keep slip frequency at constant continually by a system wherein a correction factor for the difference in diameters of driven wheels and drive wheels is computed during drifting of a vehicle and a frequency instruction for an inverter is obtained from a speed signal of the driven wheels and the computed correction factor.  
     CONSTITUTION: Speed signals f o , f o ' of a driving wheel 1 and a driven wheel 5 output from pulse generators 4, 4' are converted into digital signals (a) and (b). A dividing section 11 computes a/b and a memory 12 stores an output (c) of the dividing section 11 when a coasting signal of a vehicle is given. During operation, a multiplying section 10 performs the calculation of b×c and transmits output data (d). An additioning section 14 adds slip frequency pattern voltage V fs  to a signal (s) having been converted into digital value and the data (d), and then transmits a frequency instruction (f) to an AC power source 3 for energizing a vehicle driving induction motor 2 via a D-F converting circuit 15.

Title: Switch input circuit for on-vehicle electric accessory controller
Inventor: ISHIDA KIMITAKA
IPC: B60R16/02
Filed: 1989-01-13
Abstract: PURPOSE:To eliminate the need to alter specification according to the interposition place of a switching by holding a signal at level 'L' when an input terminal is grounded and at signal level 'H' when opened, and setting the signal level 'L' when electric power is supplied. CONSTITUTION:When the on-vehicle switching SW1 is connected and opened, a current flows to neither of the diodes 15a and 18a of photocouplers 15 and 18 because of a constant voltage diode 14, so the signal level of an output terminal To reaches 'H'. When the switch is closed, +12V is supplied from a power line BL and this voltage value exceeds the reverse yield voltage value of the constant voltage diode 14, so a transistor(TR) 18b turns on to make a connection with the output terminal To and the signal level becomes 'L'. Then when an on-vehicle switch SW2 is connected and closed, the input terminal Ti is grounded, so the TR 15b of the photocoupler 15 turns on, so that the signal level of the output terminal To becomes 'L'. When the SW2 is opened, the signal level of the terminal To becomes 'H'.

Filed: 1979-01-23
Abstract: PURPOSE: To automatically detect the entrance and exit of a preset food or the like by coactively arranging a preset food receiver, an elastic member and a detector in a refrigerator.  
     CONSTITUTION: There are arranged in an accommodating chamber 3 of a refrigerator a pair of right and left receivers 2, which are made of a slender plate having an L-shaped section and which have their ends attached to the bottom plate 17 by means of a shaft-shaped support 11 and their other ends connected to each other through a connecting plate 14. This plate 14 is suspended under a preset tension by an elastic member 4, and a detector 5 is arranged therebelow. Thus, if a container having a preset contour and a preset weight is accommodated in the chamber 3 and is placed in the receivers 2, these receivers 2 are turned downward to depress a contact 19 with the connecting plate 14 thereby to turn on the detector 5 so that the accommodation of the container is detected. If the container is taken out, the receivers 2 restore their initial positions to turn off the detector 5 so that the take-out of the container is detected. If the contours and weights of the containers are different, the impossibility of the receivers 2 takes place together with the impossibility of their downward turn.

Abstract: PURPOSE: To reduce greatly the probability of misdecision by giving the comparison to the output of the converter which converted the signals sent from the mark via two different threshold levels.  
     CONSTITUTION: Optical signals 2aW2n sent from mark positions 1aW1n on read- out slip 1 are converted into the voltage signals via photoelectric conversion elements 3aW3n each to be then supplied to two systems of comparators 4aW plus 4a'W featuring different threshold levels each. Then each output is supplied to exclusive OR circuits 7aW, and these circuits compare the output between comparators 4aW and 4a'W.

And in case even one of marks on slip 1 is unable for decision, circuit 10 delivers alarm signal 11 showing the incapability of decision. Thus the probability can be reduced greatly for the misdecision. The detection part can use the magnetic type in place of the optical type.

Title: Bar code reader
Inventor: OKABE TOSHIHIRO
IPC: G06K7/00
Filed: 1997-01-21
Abstract: PROBLEM TO BE SOLVED: To provide a device with adjustment elements and to improve the reliability of the entire device relatively inexpensively by detecting the difference between a detection signal and a delay signal to set a proper threshold. SOLUTION: When a boundary part of a variable density of a bar code passes a slit 5, the output of a reflection photo sensor 1 is linearly changed to become the detection signal having a trapezoidal waveform, and the signal passes a delay circuit 3 to become the delay signal having a trapezoidal waveform. A difference signal generation circuit 5A shows a difference signal between the detection signal and the delay signal, and it is processed by a comparison circuit 4B to output an output signal.  Since the difference signal between the detection signal and the delay signal is used to set a proper threshold in this manner, the bar code can be read without an influence of the sensitivity of the inexpensive photo sensor 1, and a bar code reader is obtained which is not required to adjust the threshold for the change of the reflectivity of a read object card or the variance of the moving speed and has a simple constitution and a high reliability.
