Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To make control authorization/inhibition judgment acurately correspond to the intention of a driver by making it necessary to shift a shift lever position into a low speed travel corresponding position from a medium or high speed travel correponding position within the specified time in addition to setting of a low speed mode for the authorization of low speed travel control. SOLUTION: A control authorization flag is turned off (S31), and whether a low speed travel mode setting switch is on is judged (S32). When the judged result is Y, whether a shift lever position is a D position is judged (S33). When the judged result is Y, clocking of specified time ΔT is started (S34), and whether the specified time ΔT has elapsed is judged (S35). When the judged result is N, whether the shift lever position is a position 2 or L is judged (S36). When the judged result is Y, the control authorization flag is turned on (S37). For the authorization of low speed travel control, it is therefore necessary to set a low speed mode and to place a shift lever in a position corresponding to low speed travel.

Title: Multilevel multiplexing function arithmetic system
Inventor: NOMI MAKOTO
IPC: G01R19/02
Filed: 1986-12-26
Abstract: PURPOSE:To eliminate the need to adjust variance in arithmetic error among respective phases which is generated when an arithmetic circuit is simplified and performs arithmetic independently by performing specific function arithmetic processing for plural analog values xi (i=1-n) which are multiplied by time division and obtaining function values f (x1-xn) which have plural analog values as arguments. CONSTITUTION:A circuit which detects the effective value (RMS) of a three- phase AC signal consists of an analog switch 1, an analog switch opening/closing control part 2, a squaring circuit 3, a low-pass filter 4, and an extractor 5. Then sampled values which are time-divided by a switch 1 indicates the mean value in the period and the circuit 3 squares the sampled values successively. Its arithmetic results are smoothed by the filter 3 to obtain the square mean value of three phases, whose square root is extracted to obtain the square root of the square mean value, i.e. RMS value. Thus, the RMS of three or many phases can be obtained by one single-phase RMS converter and an arithmetic error among the phases is eliminated because of the arithmetic circuit of one system.

Title: Rotor sign device for vending machine
Inventor: KONO MASAHIRO
IPC: G07F17/16
Filed: 1989-11-28
Abstract: PURPOSE:To secure four types of display contents which are switched to each other compared with three types secured with a trigonal prism by revolving the square pillars by themselves so as to make each circumferential face of these pillars set in parallel to each other turn to the front of a vending machine for switch of the display contents and at the same time shifting the revolution timing among those adjacent square pillars. CONSTITUTION:When the display contents are switched among square pillars 3a, 3b, 3c and 3d set in parallel with each other, the switching of display is carried out in two steps, i.e., a 1st state where the pillars 3b and 3d are revolved by 90 deg. and a 2nd state where the pillars 3a and 3c are revolved by 90 deg. respectively. In this case, the revolution timing is shifted between two states of revolution. Thus the pitch P of the parallel arrangement can be approximated up to a level where an apex 4 of the pillar 3b does not touch the faces 5 of both pillars 3a and 3c. Therefore a gap (g) can be reduced compared with a case where all pillars are revolved at one time. Then the users can see the display contents more easily. The different drive sources can be used between the pillars 3a/3c and 3b/3d so as to secure the different revolution timings between both groups of pillars.
