Title: Pulse doppler radar apparatus
Inventor: INOUE MASATO
IPC: G01S13/53
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To obtain a pulse Doppler radar apparatus which can track a frequency stably when a mounted mother machine is in a state that it nearly tracks a target by a method wherein an adjusting means is controlled in such a way that the amplitude of the composed signal of outputs from a main antenna and from a guard antenna becomes minimum. SOLUTION: The amplitude and the phase of a received signal at a wide directivity guard antenna 16 installed in the opening central part of a main antenna 4 are adjusted by a variable attenuator 18 and a variable phase shifter 19. An obtained signal S20 and a received signal S18 from the main antenna 4 are composed by an electric power composer 20. A receiver 6 to which a composed signal S21 is input generates a video signal S13. A signal processor 8 to which the signal is inputted computes the guide lobe angle of the guard antenna 16 anticipating a side lobe clutter region which radiates the same component as the Doppler frequency of a moving target when a mounted mother machine is in a state that it nearly tracks the target.  Then, both adjusting means 18, 19 are controlled by a set value which is computed in such a way that the amplitude of a composed signal 21 in its angle of depression becomes minimum. As a result, a frequency can be tracked stably when a side lobe clutter receiving level is lowered and when the mounted mother machine is in a state that it nearly tracks the target.

Title: Teletext broadcast receiver
Inventor: HAYASHI SHUNEI
IPC: H04N5/445
Filed: 1988-03-28
Abstract: PURPOSE:To prevent the broadcast audio mode of a television broadcast using a reception channel in common from displayed on the screen as it is by controlling the broadcast audio mode so as to have the screen display in the monaural mode corresponding to the teletext broadcast in the selection of the teletext reception mode. CONSTITUTION:When a recall key 12 of a remote controller 2 is depressed to display the broadcast audio mode on the receiver screen 19, a 2-audio signal 30a and a stereo broadcast signal 30b outputted from a control signal processing circuit 30 with the teletext mode are neglected and a display of 'monaural' is outputted to a character generator 39 and the display data of the number of reception channel is outputted at the same time. Thus, the monaural screen being in the present correct broadcast audio mode is applied on the screen 19 in addition to a reception channel number.

Title: Controller for image plane copying
Inventor: IWADARE TSUTOMU
IPC: G06K15/12
Filed: 1987-03-30
Abstract: PURPOSE:To permit copying of an image plane even if an operator does not make operation at a predetermined time by previously setting the predetermined time. CONSTITUTION:The time set in an image plane copying time setter 11 is stored in an image plane copying time memory device 12. An image plane copying time retrieval device 14 makes retrieval as to whether the preset time by a clock device 13 is within the memory device 12 or not and outputs a start signal P14 for retrieval of the operating condition of an image plane display device to a retrieval device 15 for the operating condition of the image plane display device when the time is within the device 12. The retrieval device 15 retrieves the operation condition signal P1 from the image plane display device 18 upon reception of the signal P14. The image plane display is required by an image plane copying request device 16 to the display device 18 and copying is requested by an image plane copying request device 17 to an image plane if the display device is not operating. The image plane is thereby displayed on a CRT at the predetermined time and the copying of the displayed image plane is permitted even if the operator does not make operation.

Title: Distributed feedback type semiconductor laser
Inventor: UKO KATSUYUKI
IPC: H01S5/12
Filed: 1988-03-30
Abstract: PURPOSE:To avoid the degradation of the yield, crystal defects and the like and improve the reliability by a method wherein the layer thickness of an active layer in which a light is generated or a waveguide layer provided closely to the active layer is periodically varied without being exposed to the air. CONSTITUTION:A first diffraction lattice 28 which has a periodical triangular uneveness is provided on an InP substrate 21 and an AlInAs buffer layer 22 is built up on it so as to have a relatively large thickness in order to reduce the influence of defects from the substrate 21. Therefore, the surface shape of the buffer layer 22 which reflects the diffraction lattice 28 on the substrate 21 is obtained. As the buffer layer 22 is built up on both the side slants of the respective valley parts (recesses) of the diffraction lattices simultaneously to the directions vertical to the slants, the surface of the buffer layer 22 is somewhat flat. Therefore, if an AlCaInAs active layer 23 is further built up on the buffer layer 22, its layer thickness is periodically varied by the reflection of the diffraction lattice 28 on the substrate 21. Further, a p-type AlInAs cladding layer 24 and a p-type CaInAs cap layer 25 are built up. With this constitution, the AlCaInAs active layer 23 can be kept apart from the diffraction lattice 28 which tends to cause crystal defects so that a DFB laser which has few crystal defects and the high reliability can be obtained.

Filed: 1986-04-01
Abstract: PURPOSE:To lower the dependency on a program by providing a code data ROM for making the counted value of a clock counting circuit a code and a clock control circuit for stopping the clock of a clock generating circuit when a change point detection circuit detects a change point. CONSTITUTION:When the change is generated in a picture data signal (d), it is detected by an exclusive OR circuit 132, by applying the change to the change point detection circuit (f), a D flip flop 141 is triggered, and a control signal (b) rises. According to the H level of the control signal (b), the clock of the clock generating circuit 12 is not propagated, and a clock signal (c) is stopped to maintain an L level. The clock counting circuit 7 is counted by the rise of the clock signal (c), when the change point appears in the picture data (d), the signal (c) holds the L level and the counted value (g) of the signal (c) immediately before the change point appears in the picture data (a) is outputted. The code data ROM 15 inputs the counted value (g) and outputs code data (h). Thereby, the dependency on the program can be reduced.

Abstract: PURPOSE:To assure the straight movement of the bit of a drill, by protruding a tip portion of the cutting part of the drill at the bit. CONSTITUTION:The tip portion 13 of a cutting part 12 provided at the bit 1 of a drill is protruded nearly in the form of a trapezoid. Cutting reaction forces act to protruded edges 13a, 13b, 13c. As a result, one of guide pads 9a, 9b is prevented from receiving the cutting reaction forces concentratedly. The protruded edges 13a, 13b, 13c cut into a workpiece so as to perform a restricting action for keeping the drill bit 1 from being displaced in the radial direction. The straight movement of the drill bit 1 is thus assured.
