IPC: H03M1/36
Filed: 1990-05-22
Abstract: PURPOSE:To obtain a stable digital output even when there is an analog input value by executing A/D conversion with hysteresis to an input analog voltage while controlling one switch to be closed when the other switch is opened based on the digital output and shifting a decision reference voltage. CONSTITUTION:This A/D converter is composed of resistors 3a and 3b for shift respectively serially connected to the power supply voltage side and low potential side of a resistance ladder 1 to obtain the plural decision reference voltages, and switches 4a and 4b respectively parallelly connected to these resistors for shift. Further, hysteresis circuits 10a and 10b are provided to execute A/D conversion with the hysteresis to the input analog voltage while controlling one switch to be closed when the other switch is opened, and shifting the decision reference voltage based on the digital output. Thus, without requiring any large scale or complicated circuits, the A/D converter can be realized with the hysteresis characteristic and even when there is fine fluctuation due to the noise, etc., of the input analog voltage or the analog input value near a comparative voltage, the stable digital value can be obtained.

Title: Multipolar connector requiring little attaching-detaching force
Inventor: KUZUNO KATSUTOSHI
IPC: H01R13/629
Filed: 1987-05-29
Abstract: PURPOSE:To facilitate the attaching and detaching operation to be performed in a narrow space by causing a slider, which constitutes a cam mechanism for engaging and disengaging two housings, to be ordinarily installed on either one of the two. CONSTITUTION:A projected housing 2 is inserted into the recessed body 7 of a recessed housing 1. The insertion is carried on until the cam follower 21 of a temporarily locked slider 3 reaches the back wall of the inlet part 25a of a guiding groove 25. When the slider 3 is then moved to the left, the housing 2 approaches the housing 1 by means of the groove 25, which is engaged with the follower 21, and comes in sliding contact with a gentle slope of the groove 25 so that an engagement is completed with only a small force. If the operation of the slider 3 at the time of detaching is performed in such a manner that the central part of a pressing part 18, that is, the middle part between rails 11,12, is pressed with the tip of a finger, the angular moment is little and a wasteful force is unnecessary. Since the slider 3 is installed on the housing 1 in advance, a space for the installation thereof is not required specifically. Thereby, the attaching and detaching operation in a limited narrow space is made possible, and the force required for the attaching and detaching operation can also be made smaller.

Abstract: PURPOSE:To enhance the integration degree of a circuit by cascading the first TTL circuit and the second TTL circuit and making collector load resistances of respective output transistors common. CONSTITUTION:Signal inversion A0 having a polarity opposite to input signals A0 is obtained form the output terminal of the first TTL circuit dependent upon transistors Q1-Q4.

If transistor Q4 of the first TTL circuit is turned on (off), transistor Q4 of the second TTL circuit is turned off (on), so that no excessive load may be applied to resistance R4. As a result, the number of parts of the circuit can be reduced.
