Title: Data input system
Inventor: TAKAHASHI KENICHI
IPC: H04B10/00
Filed: 1984-04-18
Abstract: PURPOSE:To check always the condition of establishment of an optical transmission path by transmitting a monitor signal, which monitors the connection state between a main device and a data input part, from an main device with optical space propagation. CONSTITUTION:In the side of a main device 11, the transmission of the monitor signal which monitors the connection state between the main device 11 and a data input part 21 is indicated by a control part 6, and this signal is transmitted to the data input part 21 as an optical signal by an optical signal generating circuit 2' and a light emitting element 3. In the input part 21, reception or non-reception of the optical signal which monitors the connection state is judged by a photodetector 4' and a signal detecting circuit 5', which detects the light reception state of the photodetector, to discriminate whether the optical transmission path is established well or not. If the monitor signal is received, it is judged that transmission is possible, and an input operation part 1 is operated to transmit input data to the main device 11 as an optical signal from the light emitting element 3 through an optical signal generating circuit 2. The device 11 receives this optical signal by a photodetector 4 and converts it to an electric signal and sends it to the control part 6 as input data through a signal detecting circuit 5. If the monitor signal is not received by the input part 21, it is judged that transmission is impossible, and the transmission impossible state is reported.

Patent JP-H01253331-A (JP)
Title: Radio circuit control system
Inventor: OTA YUJI
IPC: H04B7/26
Filed: 1988-04-01
Abstract: PURPOSE:To avoid such an inconvenient case where no fixed device designated by a main device exists by holding a designated state received from the main device until the control signal showing the release of said designation is received from the main device. CONSTITUTION:A fixed device C receives the calling signal from a portable telephone via a radio circuit and transmits this signal to a main device. Thus the main device transmits a designation release signal as well as a designation signal to inform the designation to another fixed device D. The device C release its fixed state with reception of the designation release signal from the main device. Thus the fixed device does not release its own designated state by itself as conventional but releases the designation by the control signal received from the main device. Thus it is possible to avoid such an inconvenient case where no fixed device kept under designation of the main device exists even though the designated state is not accepted by the main device.

Title: Distributed feedback type semiconductor laser
Inventor: HIRATA SHOJI
IPC: H01S5/12
Filed: 1987-03-30
Abstract: PURPOSE:To freely select the length of a phase shifting region by varying the effective guide layer thickness of a diffraction grating in a waveguide direction. CONSTITUTION:In a distributed feedback type semiconductor laser having a first clad layer 2, an active layer 3, a guide layer provided with a diffraction grating 5, and a second clad layer 6 so that a waveguide is formed in a stripe state. the guide layer thicknesses of the grating 5 in the waveguide direction are differentiated to vary the phase of a guide light. That is, the thickness of the layer 5 of the forming section of the grating 5 is different in the waveguide direction to apply a variation to the lateral mode distribution in y direction, lambda/4 phase shift is effectively performed by an effective refractive index difference  N generated thereby to generate a single longitudinal mode oscillation. Thus, since the effective thickness difference (h) of the layer 4 with the phase shifting region 21, other diffraction grating region 22 is arbitrarily controlled, arbitrary refractive index difference AN is obtained to freely set a desired phase shifting region length l.

Title: Controller of air fuel ratio
Inventor: KITAHARA TAKESHI
IPC: F02D41/14
Filed: 1983-05-06
Abstract: PURPOSE:To measure continuously an air-fuel ratio lower than a logical air- fuel ratio by controlling a flow-in current according to the air-fuel ratio in exhaust air so that a sensor output voltage coincides with a target output abrupt varying voltage. CONSTITUTION:When the air-fuel ratio in the exhaust air varies to a value smaller than the specific air-fuel ratio, the flow-in current Is of an operational amplifier 19 does not vary, so the output voltage Vs of a oxygen sensor element 1 varies. Then, the flow-in current from the operational amplifier 19 whose target voltage is set corresponding to the current Is varies according to said variation, and the voltage Vs further varies. On the other hand, a target voltage generating circuit 28 is controlled through a current measuring circuit 21 which responds to the variation i current Is, and the target voltage is controlled to coincide with the voltage Vs, and to obtain a value corresponding to an abrupt varying air-fuel ratio. A sensor which generates an output following up the air- fuel ratio after the variation as the output abrupt varying air-fuel ratio detects the air-fuel ratio lower than the logical air fuel ratio continuously to perform air-fuel ratio control with high precision.

Filed: 1993-03-11
Abstract: PURPOSE:To eliminate the need of securing the installation space of a sensor and increasing cost by measuring the density of an original image without providing an exclusive sensor. CONSTITUTION:In a process for detecting the density of the original image, the latent image of the original image is formed on a photosensitive body 2 and toner is not stuck. Then a constant current control means 62 and a power source for a transfer roller 61 are started up and a constant current (transfer currenjt IR) is made to flow from a transfer roller 60 to the photosensitive drum 2. A voltage detecting means 65 detects a voltage (transfer voltage VR) at this time. The transfer voltage VR correlates with the density of the original image. The result of the detection is averaged by an average value calculating part 66a and further, a developing bias arithmetic part 66b sets an optimum developing bias (target value), in consideration of the average value. A voltage adjusting means 67 changes a developing bias according to a signal from the developung bias arithmetic part 66b. In this toner image of an optimum density can be formed and a latent image can be formed again the photosensitive drum 2, and developed by a developing device 5.
