Filed: 1990-03-08
Abstract: PURPOSE:To obtain a neural network with optimum structure corresponding to a static/dynamic processing by providing a feedback intermediate layer separately from a general intermediate layer and freely connecting this feedback intermediate layer to the front or rear step of the general intermediate layer. CONSTITUTION:In the condition of t=1, an output OUT under the condition of t=0 is fed back to a feedback intermediate layer X and in the condition of t=2, the output OUT at the time of t=1 is fed back to the feedback intermediate layer X. Therefore, when repeating these operations, the coupling degree of each feedback synaps couple is made active and a dynamic non-linear model can be constituted as a whole neural network. On the other hand, when executing normal pattern recognition, the feedback intermediate layer X is detached. Namely, a general intermediate layer A is directly connected to an input layer S. Thus, corresponding to the static/dynamic processing, the optimum neural network is obtained.

IPC: G02B27/00
Filed: 1988-03-11
Abstract: PURPOSE:To prevent incidence of ghosts and flares to a light receiving means and to enable focus detection wit high accuracy by setting the distance measurement region on a desired imaging plane so as to deviate from the region formed as a projection pattern is moved point-symmetrically with the optical axis of an objective lens. CONSTITUTION:The ghosts are generated in the region 74. The region 72 is the range where strong ghost light enters, the region 73 is then range where the middle ghost light enters, and the region 74 is the range where the slight ghost light enters. Namely, the strong ghost is generated in the position where the slit projecting part turns back with respect to the optical axis of the objective lens. The distance measurement region on the desired imaging plane by the 2nd detecting system is, therefore, set in the region deviated from the region 72 formed as the projection pattern is moved point-symmetrically with the optical axis of the objective lens. The ghosts and flares are thereby prevented from entering the light receiving means and the focus detector which is capable of making the focus detection with always high accuracy is obtd.

Title: Receiver for television text multiplex broadcasting
Inventor: HAYASHI SHUNEI
IPC: H04N5/44
Filed: 1988-03-11
Abstract: PURPOSE:To improve the handling performance of the title receiver by invalidating a channel preset state when the character broadcast pictures are displayed. CONSTITUTION:It is checked whether an input key 22, for example, is equal to a preset key 22P or not. If so, it is checked whether the present display mode is equal to a character broadcast display mode or not. Then a channel presetting process is carried out when the present display mode is not equal to the character broadcast display mode (including a mode where the character broadcast pictures are superimposed on a TV broadcast screen). While the presetting action of the relevant channel is inhibited or ignored even though the key 22P of the channel is pushed when a character broadcast display mode is confirmed. Thus it is possible to prevent the occurrence of a trouble where a scanning action lasts forever by mistake or to avoid the clearing of the data on a preset channel.

IPC: H04N1/23
Filed: 1988-03-14
Abstract: PURPOSE:To prevent the destruction of a laser diode by holding the command of the light quantity of the laser diode when the decreasing rate of a feedback signal exceeds a certain value. CONSTITUTION:A laser diode LD control part 1 forms a recording signal WD according to recording data and forms a light quantity command value CO according to the light quantity feedback signal DL of an LD 2, and it is added to an LD driving part 3 as an analog light quantity command value AC by a D/A converter 4. A voltage from a power source supply part 5 is added to the driving part 3 and a current corresponding to the command value AC is supplied to the LD 2 according to the signal WD. The LD 2 is turned on/off according to the signal WD. A part of laser light is added to the control part 1 as the feedback signal DL. A voltage to the driving part 3 is applied to the control part 1 as an interlocking switching actuation signal IL. When the signals IL are continuously outputted for a certain time or more, the control of the LD 2 is stopped and the command value CO is set, then the signal WD is stopped. Thus, the destruction of the laser diode can be prevented.

Title: Method for checking mask for printed substrate
Inventor: HARA YASUHIKO
IPC: G01B11/24
Filed: 1981-04-20
Abstract: PURPOSE:To avoid the detection of the concave and convex parts, on which a pattern is not described, as defective product, in checking of the mask for the printed substrate, by adjusting the scattering degree of the illuminating light for the mask. CONSTITUTION:The illuminating light 2 is applied to the mask 1 for the transparent printed substrate on which the pattern is described, and the image of the mask 1 is projected on a pattern detector 4 through a lens 3. The output 5 from the detector is processed in an image processor 6, and the defects are detected. If the concave and convex parts are present at the part where the pattern is not described on the mask, the illuminated light is refracted from the slant surfaces of said concave and convex parts and does not reach a lens. Therefore it might be regarded as the defect. By using a scattering plate 8, an angle is imparted to the incident light axis of the illuminating light to the mask so that the light can reach the lens even though it is refracted. Since the detecting capability for the concave and convex parts is determined by the degree of parallelism of the transmitted light, it is recommended that a plurality of the scattering plates having different scattering degress are prepared.
