Abstract: PURPOSE:To easily finely adjust the set frequency of laser light by controlling oscillation of a semiconductor laser based on respective detection results of a photoelectric power detecting part and a wavelength detecting part. CONSTITUTION:The oscillation output of a semiconductor laser 11 is branched into two, and one is led to a first photoelectric power detecting means 18 to detect the photoelectric power.

Title: Tape recorder
Inventor: YOSHIKAWA TADASHI
IPC: G11B15/02
Filed: 1980-04-15
Abstract: PURPOSE:To improve the quality of recording in the winding beginning part of a tape by so constituting the recorder that when the tape arrives at the tape winding beginning in the tape rewinding state having been set by opening and closing of a switch shifts to the silent recording state. CONSTITUTION:When a tape rewinding operation is started by closing a switch 8a at the time ta, the tape is completely wound to the supplying reel turntable side, and stops running at the time tb. When the time tc after a constant time from the time tb is reached, a mechanism 10 changes over automatically from the rewinding operation to recording via buffers 6a, 6b, etc. Further, after the time tc, the recording is continued while recording is being muted via an FF circuit 12, etc., and the silent part is made for a constant time from its winding beginning. When the pulse signals entering a counter 14 reaches constant number of times after the time tc, the recording muting is released at td and the mechanism 10 assumes the recording pause state. With such constitution, the constant section of the tape winding beginning where level fluctuations or the like are frequent is made silent part and this improves the quality of recording.

IPC: G08C19/02
Filed: 1989-03-03
Abstract: PURPOSE:To prevent the collision of signals on a signal transmission line without requiring any special equipment and to attain simple communication by allowing a transmission side to make transmission while confirming the absence of a signal for a prescribed time or more on a transmission line and allowing a reception side to send a signal representing a busy transmission line for a shorter interval than a prescribed time till a reply signal is returned. CONSTITUTION:A reception meter 3 sends an intermitting signal for a prescribed interval or below only indicating the busy state of a signal transmission line 5 or a continuous signal to the signal transmission line 5. Thus, whether or not the signal transmission line 5 is busy is confirmed only by confirming that no signal exists on the signal transmission line 5 for a prescribed time or above and the priority over other communication equipment or the like is ensured when the use of the line is once started. Then a field sensor 1 and a communication equipment 2a make easily communication with each other asynchronously without requiring any special equipment such as a priority setting device.

Abstract: PURPOSE: To detect the variation of the infrared rays accurately even though the operation is small, and to prevent an error operation, and to reduce the off-delay time, by making the interval of the centers of the plural detected beams formed at the front side of a converging part, narrower than the width of a human body. CONSTITUTION: When each light receiving surface of an infrared-ray is made is a square with one side 1.1mm, and the interval of the receiving surfaces is 1.5mm, for example, the distance between the centers of the light receiving surfaces is made 2.6mm, and in this case, when the optical distance of a lens at the converging part is made 26mm or more, for example, the interval between plural detecting beams B at 2m at the front side (or the lower side) of the converging part is made about 20cm, and the cross section of the beam B is made in a square with one side 8.5cm. When a detecting device is installed to a ceiling, the human body M to be the object to detect is regarded as a rectangle of about 40cm×20cm, when he is an adult.  Since the interval of the beams B is made less than 20cm to the shorter side of the rectangle, at least one beam is applied to the human body M constantly, and even though a part of the human body M is moved a little, it can be detected as a variation of the infrared rays.

Abstract: PROBLEM TO BE SOLVED: To reduce consumption power and enable massproduction by applying Colioli's force due to angular velocity to a weight on a diaphragm, and detecting displacement of the diaphragm which is caused by the Colioli's force, as an electrostatic capacity. SOLUTION: A weight part 3 of a frame body 2 is provided with weights 10a-10d and arranged on a retaining plate member 4 whose bottom part is a diaphragm 12. An electrode part 5 formed in a bottom plate member 6 consists of driving electrodes 19, 20, angular velocity detecting electrodes 21, 22, etc. Each of the electrodes 19-21 are formed at positions almost facing the respective corresponding part positions of the diaphragm 12. When an AC signal as a driving signal is applied to the driving electrodes 19, 20, the weights 10a-10d are vibrated together with the diaphragm 12 by the action of an electrostatic force.  In this state, when a rotating force acts around a Z axis, Colioli's force is generated in the weights 10a-10d, displacement of the diaphragm 12 is generated, and electrostatic capacities between the detecting electrodes 21, 22 and the corresponding diaphragm 12 are changed. An angular velocity around the Z axis can be measured from the absolute value of difference between the respective electrostatic capacity values of the detecting electrodes 21 and 22.
