Title: Overrun preventing device
Inventor: OCHI TAKESHI
IPC: B61K7/16
Filed: 1977-12-22
Abstract: PURPOSE: To simplify an overrun preventing device by constructing a responder carried on a vehicle with a resonance circuit consisting of a loop coil capacitor electromagnetically coupled with a ground loop antenna and a resonator for a fail- safe ground device.  
     CONSTITUTION: The output of a coupling discriminating circuit 38 becomes a logic level "1" when a responder 50 carried on a vehicle responds, alternating signal of logic levels "1" and "0" when only a pseudo-responder 35 responds, and a logic level "0" when none of them responds. Accordingly, relays 42, 42' operate only when the pseudo-responder 35 responds. The output of the circuit 38 is applied to an integration shaping circuit 39, and a relay 43 is, therefore, operated only when the responder 50 responds. Speed discriminating circuits 44 to 46 discriminate the speed of the vehicle according to the interval of the response signals generated from the responder 50 in response to the crossing of ground loop coils 34. Thus, it can siplify the overrun preventing device and yet prevent the vehicle from overrunning.

Abstract: PURPOSE:To equalize a response wait time and to improve serviceability for subscribers by receiving in the order of subscribers' responses and the order of incoming calls when the incoming is given to plural subscriber groups capable of individual incoming. CONSTITUTION:When the incoming is given to a trunk line trunk 1 from a trunk line and when a central control unit 4 decides it to be a direct in-line trunk line, an extension subscriber containing position is decided. For example, when the containing position of an extension subscriber SUB-A is set with respect to the trunk 1, an incoming display is given to the SUB-A, and various kinds of information necessary for the exchange processing of call control information is set. Then, respective tables for subscriber and COT controls are linked with the call control information, and the incoming time of the trunk line is entered, thereby transmitting a calling signal only to the subscriber SUB-A. When the trunk line incoming is given to a trunk line trunk 2 in said state, an extension subscriber SUB-B is called similarly. Upon response, the subscriber SUB-B is connected to the trunk 1 whose incoming call is earlier. With respect to the SUB-A, the contents of call control information is so switched as to carry out the incoming of the trunk 2.

Title: Digital filter
Inventor: TATEBAYASHI KIYOHIKO
IPC: H03H17/02
Filed: 1982-09-08
Abstract: PURPOSE:To control the pass band of a digital filter over a wide range only by changing a sample frequency, by controlling a cut-off frequency of a low-pass filter for AD and DA conversion proportional to the sampling frequency. CONSTITUTION:An analog signal is inputted from a terminal 1, the band is limited through a low-pass filter section 2 located at the pre-stage so that the frequency reflexing due to sampling is not produced, and converted into a discrete data with equal interval at an AD converting section 3, and the filter transfer function is operated at a digital filter operating section 4. The digital converted signal is inverted into an analog signal at a DA convering section 5, a harmonic component is eliminated at a low-pass filter 6 located at the post- stage, and the result is outputted to a terminal 8. Since a control section 7 generates a sampling pulse S1, cut-off frequency control signals CS1, CS2 proportional to the sampling frequency and a sequence control signal S2, the pass band is controlled only by changing the sampling frequency.

Title: Converting system of decimal number and binary number
Inventor: IBE HISASHI
IPC: H03M7/08
Filed: 1981-09-30
Abstract: PURPOSE:To increase a speed of converting operation, by checking whether the byte concerned is all zero or not at every 1 byte from the upper rank part of a converting data, and omitting the converting operation by the number of zero connected in the upper rank part of the converting data. CONSTITUTION:In case of a CVB instruction, as for an operation of B'j=B'j-1X 10+dj, 4 operation cycles consisting of shifting operation of 2 times and adding operation of 2 times are required, but as for a speed for skipping the operation, it can be executed by about 1.5 operation cycles by deciding whether the upper rank byte is zero or not. Accordingly, the operation cycle of a converting data of 40 bits becomes as follows: 1.5 operation cycles + converting operation 10 times, when 1 byte ''0'' is not ''0''. 3 Operation cycles + converting operation 8 times, when byte ''1'' is ''0''. 4.5 Operation cycles + converting operation 6 times, when byte 2 is ''0''. 6 Operations cycles + converting operation 4 times, when byte 3 is ''0''. 7.5 Operation cycles + converting operation 2 times, when byte 4 is ''0''. In this way, except the case when byte ''0'' is not ''0'', the operating  speed is increased.

Abstract: PURPOSE:To obtain efficient binary coding at each object picture by adding accumulatingly a product between a digital value and a differentiation digital value at each picture element in a range to be binary-coded and using the sum divided by the accumulated sum of the differentiation digital values as a binary-coded threshold value. CONSTITUTION:A contrast picture is A/D-converted and the output is inputted to a delay circuit 3 and a differentiating circuit 4. The differentiating circuit 4 applies Laplacian operation of NXN picture elements to obtain a prescribed differentiation value. In order to obtain a value weighted by the differentiating value of a picture element, the output value of the delay circuit 3 and the differentiating circuit 4 is inputted to a multiplier 5. An adder 6 adds the value from the multiplier 5 at each picture element over the entire pattern and the sum is divided by the addition data of the differentiation data obtained by an adder 7 as to all the pattern at a divider 8. The obtained value is used as a binary-coded threshold value of a contrast picture signal 1. In order to decide the binary-coded level, the range to be binary-coded for the entire pattern is inputted once to the device and then binary-coding is applied in the timing of the pattern input.
