Title: Phototodetecting method and device for the same
Inventor: DAIBUTSU KAZUTAKE
IPC: G01S5/16
Filed: 1990-02-27
Abstract: PURPOSE:To preclude malfunction and misoperation due to disturbing light from a fluorescent lamp, etc., by storing maximum light receiving signals in three sampling periods respectively, and comparing the stored results and deciding a noise. CONSTITUTION:A rotating laser beam which is used for survey, etc., is converted by a 1st sensor 11 above a detector into an electric signal, an A/C coupling 13 removes a DC noise components due to the sunshine, etc., and the converted electric signal in each sample period is held by a peak holding circuit 31 which is reset by a reset circuit 41 controlled by a CPU 53 through a timer 52 and then stored in a RAM 55 through an A/D converter 51. Then a CPU 53 compares the maximum converted electric signals in the three sample periods from the RAM 55 to decide that one signal is correct only when other two signals are equal and one signal is large while deciding that all signals in other combinations are AC noises such as a fluorescent light noise, thereby precluding the malfunction and mismeasurement. The up-down position of a detector is detected according to the result of comparison with a similar processing result through a 2nd sensor 12.

Filed: 1981-03-30
Abstract: PURPOSE:To attain the quick recovery of a fault for a key telephone device and to ensure the quick response of a user, by installing a circuit that monitors fault arisen at a trunk line circuit of the telephone device. CONSTITUTION:In case contacts 27 and 28 are kept closed although a trunk line circuit 15 is rung off, the loop of a trunk line 6 is held continuously. Thus one of the light emitting diodes 25 and 26 emits the light, and as a result one of the phototransistors 29 and 30 is turned on. Then the presence or absence of the loop current is informed to a control means 14 from a comparator 34. On the other hand, the means 14 deects the ring-off through a terminal interface circuit, and a fault is decided by the detection of the ring-off and the output signal given from the comparator 34. Thus a fault is displayed. As a result, the user of a key telephone device can know the fault of the trunk line to a quick response for repair, etc.

Title: Mobile radio communication device
Inventor: HIRASHITA TAKEMASA
IPC: H04B1/3822
Filed: 1983-03-24
Abstract: PURPOSE:To improve the operability as well as to prevent a malfunction of a mobile radio communication device by performing the setting of frequency for all frequency transmitting/receiving devices and the resetting of a receiver for selection call through a resetting part. CONSTITUTION:When a selection call is given with a frequency F2 to a mobile station 40 from a fixed station, a receiver 12 for selection call receives the selection call and actuates an informing mechanism 13. An operator knows a call and operates a resetting part 21. Thus the receiver 12 is reset with a one- touch operation, and at the same time the mechanism 13 is reset. At the same time, the oscillation frequency of a local oscillating part 15 is switched and set so that the transmission and reception are possible with the frequency F2. Therefore the handling is simplified for a mobile radio communication device, and at the same time the part 21 is actuated with the output signal of the receiver 12 only in case no reception is performed for a prescribed period of time before a time point when the receiver 12 is actuated. Thus it is possible to prevent the switching during reception for all frequency transmitting/receiving devices and also to perform all operations in a fully automatic way.

Abstract: PURPOSE:To improve resolution of a color image by exposing the same part of a photosensitive member by the use of a red shutter three times, a green shutter and a blue shutter while relatively displacing a liquid crystal shutter and the member in a predetermined direction. CONSTITUTION:After a predetermined part of a photosensitive member 5 is exposed with a red light by using a red shutter 14R, moving means 6A, 6B, 7 are driven to relatively displace the member 5 and its liquid crystal shutter 14. After the predetermined part of the member 5 is further exposed with a green light by using a green shutter 14G, the means 6A, 6B, 7 are driven to again relatively displace the member 5 and its liquid crystal shutter 14. The predetermined part of the member 5 is eventually exposed with a blue light by using a blue shutter 14B, and the predetermined part of the member 5 can be colored with an arbitrary color in a mixture color manner. Accordingly, since the area of a color pixel of a minimum unit to be colored in an arbitrary color is made equal to that of an image of one microshutter such as the shutter 14R, etc., in principle, the resolution of the color image can be improved approximately three times.
