Inventor: YAJIMA NOBORU
IPC: H04B10/00
Filed: 1988-12-02
Abstract: PURPOSE:To eliminate the need for an optical attenuator and to avoid the limitation of a transmission distance by using a melting type photocoupler whose branch loss ratio is unbalanced as a photocoupler. CONSTITUTION:A melting type coupler is employed as a 1st photocoupler CP 1 and a 2nd photocoupler CP 2 and the optical branch loss ratio (branch loss ratio) is unbalanced as 1dB:7dB. That is, the branch loss of the optical coupler in the directions of CN1, OS1 and directions of CN2 and OS2 is increased and the branch loss in the directions of CN1, OR1 and in the directions of CN2 and OR2 is decreased. Thus, the melting type optical coupler is employed causing an unbalanced direction loss, then nearly the same degree of attenuation effect as that by the optical attenuator is obtained. Thus, the melting type optical couplers whose branch loss ratio is nearly 1dB to 7dB as the optical couplers CP1, CP2 and the coupler having a larger loss is used for the optical transmission section side to eliminate the need for the optical attenuator.

Title: Preventing method for beat fault of fm radio receiver for vehicle
Inventor: TSUKAHARA HITOSHI
IPC: H04B15/04
Filed: 1986-12-23
Abstract: PURPOSE:To prevent a beat fault from being given on an FM radio receiver, by setting the frequency of a clock pulse at a level less than that of an FM radio broadcast, and also setting it at the frequency in which the high harmonic component of the frequency is not included in the frequency band area of an FM radio. CONSTITUTION:A microprocessor 1 performs prescribed control based on a periodical clock pulse from a clock pulse oscillation circuit constituted with a quartz oscillator 3, and capacitors 4 and 5. Thereupon, to prevent a beat tone from being generated even when the FM radio receiver 7 receives an FM broadcasting station with an arbitrary frequency, the frequency of the clock pulse is settled so that no high harmonic component exists in an FM broadcasting frequency band area. In such way, since the high harmonic component of the clock pulse can be prevented from being mixed in the frequency band area of the FM radio broadcast, it is possible to prevent the beat fault from being given on the FM radio receiver for a vehicle by the high harmonic component of the clock pulse of an on-vehicle electronic equipment.

Filed: 1986-12-23
Abstract: PURPOSE:To enhance measuring accuracy by changing stepping voltage according to the magnitude of the change quantity of an electrolytic current and reducing said stepping voltage in a part where the change quantity of the electrolytic current is large. CONSTITUTION:Predetermined voltage is stepwise applied between the acting electrode 40 and opposed electrode 42 of a measuring cell 51.

CPU 49 controls the sampling point of time of the digitized electrolytic current and the sampled electrolytic current is stored in a memory. CPU 49 subtracts the electrolytic current signal of the previous stage from said electrolytic current signal and calculates the change quantity of the electrolytic current due to stepping voltage. Next, this change quantity is compared with a threshold value and, on the basis of the magnitude relation between both of them, the stepping voltage to be applied to the next stage is set.
