Title: Chain transmission mechanism
Inventor: ICHIKAWA MASAHIKO
IPC: F16H7/06
Filed: 1988-03-29
Abstract: PURPOSE:To prevent vibration of a rotary shaft, by a method wherein a plurality of sprockets are mounted on a rotary shaft in a manner to displace phases from each other, and independent chains are run around respective sprockets. CONSTITUTION:A sprocket 3 is rotatably mounted on a rotary shaft 1 through bearings 4 and 5, and a second sprocket having the same pitch circle diameter and the same number of teeth as those of the sprocket 3 is spline-engaged with a boss part 6 of the sprocket. The rotary shaft 1 can be coupled to the boss part of the sprocket 3 through a slide clutch 10, and integral rotation is practicable. The sprockets 3 and 7 are mounted in a manner to displace phases from each other by a half pitch. Through vertical displacement produced at silent chains 11 and 12 independently run around the sprockets 3 and 7, respectively, vibration is offset to each other by means of displacement in a phase, and vibration transferred to the rotary shaft 1 is prevented from occurring.

Title: Signal detector
Inventor: MAEDA KIYOHARU
IPC: H04L27/00
Filed: 1984-04-13
Abstract: PURPOSE:To secure the flexible and general-purpose properties to the change of frequencies and at the same time to attain the miniaturization and integration of a signal detector which detects a single frequency signal out of the reception signal supplied from a communication channel, by detecting digitally said single frequency signal. CONSTITUTION:When a signal e1 is applied to an input terminal IN from a communication channel, the signal e1 is sliced by grounding at a slicer 11 and magnetism and converted into a rectangular signal. This rectangular signal is converted by a pulse producing circuit 12 into a pulse signal showing a cycle. The output Sig1 of the circuit 12 is turned into a pulse signal having a random cycle when the signal e1 is not equal to a prescribed single frequency signal. While a pulse signal having a cycle T0/2=1/2X1/f0sec is obtained when the signal e1 is equal to a prescribed single frequency signal. The single frequency signal generally has an allowed frequency deviation and therefore said cycle T0=1/f0sec also has the time width. Therefore the signal applied to the terminal IN is equal to a prescribed single frequency signal as long as the cycle of the pulse signal of the output of the circuit 12 is set in a range between the minimum cycle Tmin sec and the maximum cycle Tmax sec.

Title: Detector switch
Inventor: ARAKI AKIRA
IPC: H01H13/18
Filed: 1993-02-25
Abstract: PURPOSE:To provide a detector switch of simple structure and high operational reliability by forming a movable terminal member of an elastic material so that the movable terminal member may have its contact action with a stationary terminal member always at a predetermined position and its return action to its original position. CONSTITUTION:When a tapped 7 having its head portion projected outward from the surface of a cover 3 is loaded with a tape pack, a compact disc or the like, or when it is moved under pressure by another means, a movable terminal member 6 uses one end portion 6a thereof for a fulcrum to be moved in the direction of an arrow while being bent. This movement causes the turnup portion 6b of the movable terminal member 6 to be brought in slide contact with the surface of a stationary terminal member 5 with coming in sufficient elastic contact therewith. In this slide contact process, electrification occurs between another stationary terminal member 4 and the stationary terminal member 5 via the movable terminal member 6 so that a detector switch may detect loading a tape pack, a compact disc or the like on the tapped 7, or a change in the operational condition of another means. When the tapped 7 is released from its pressured condition, the movable terminal member 6 returns to its original position by its own elasticity while allowing also the tappet 7 to return to its original position.

Abstract: PROBLEM TO BE SOLVED: To absorb the deviation of data transfer time and to maintain a line between both devices by sequentially storing picture data received from a transmission-side facsimile equipment through a radio communication network and controlling the transmission timing of picture data to a reception-side facsimile equipment based on stored picture data. SOLUTION: When a control circuit 21 obtains a monitoring result that data quantity in an absorption RAM buffer is less, namely, the data transfer speed of picture data is slow through a monitoring circuit 18, a receptionside G3 facsimile adapter device 15 receives and recognizes a reception completion signal from the reception-side general-purpose G3 facsimile equipment 12, sets the timing of the transmission of picture data transmitted from the communication control circuit 20 to be prescribed later and delays transmission timing. When the monitoring result that the data transfer speed of picture data is fast is obtained, the transmission timing of picture data transmitted from the communication control circuit 20 is made faster than regular transmission timing.

Filed: 1987-03-30
Abstract: PURPOSE:To reduce ripple and noise, by limiting the range of pulse width control of each pulse width control circuit within the input period of synchronous pulse signals, and by shifting each input synchronous pulse signal. CONSTITUTION:A switching regulator is composed of the first and second regulator sections 11 and 12 of the same constitution.

No dead time control circuit is required to be added to each regulator section 11 and 12, because the duty is limited to 50%, so that the circuit is simplified and the reliability improved.
