Title: Diffusing plate
Inventor: TAKAHASHI TOSHIAKI
IPC: G03B13/24
Filed: 1977-12-16
Abstract: PURPOSE: To make it possible to easily produce a diffusing plate such as the focal plane of a camera having desired diffusing characteristics, through the change in the patterning of a mask of a fine structure, which is formed on a soluble substrate, by dissolving the substrate through the mask.  
     CONSTITUTION: A photosensitive film 4 of a photosensitive resin is applied to a  substrate 3 of acid-soluble glass, and a pattern 5 printed on glass 6 is brought into contact therewith for an exposing purpose at 7. As a result, the insensitive or photosensitive portion is dissolved and removed to leave a net-shaped photosensitive film 4 having a net width desirably less than 10 microns. After the side of the substrate 3 left unetched is protected by a protecting film 9, the surface of the substrate 3 is etched with a treating liquid such as nitric acid. After the film 4 is then removed, the surface is softly etched to smoothen the rough portions thereby to reduce the drawback that the range finding accuracy is deteriorated and that there is abrupt difference n brightness between the center and the peripheral portion.

Title: Hydraulic type overload releasing device
Inventor: AOYAMA SUSUMU
IPC: B30B15/02
Filed: 1985-07-12
Abstract: PURPOSE:To speed up the resetting to a normal state from an operative state by constituting the titled device in such a manner that the pressure oil in a high pressure side oil chamber is conducted to the inside of a low pressure side oil chamber in the operation stage and that the oil liquid in the low pressure side oil chamber is returned to the high pressure side oil chamber in the resetting stage. CONSTITUTION:The oil chamber A formed between a piston 11 and a cylinder 12 is segmented to the high pressure side oil chamber 15 and the low pressure side oil chamber 16 when a partition wall part of the cylinder 13 of the cylinder 12 and a projecting part 14 of the piston 11 contact with each other. The top surface of the piston 11 functions as a load supporting base part 26 when the oil pressure is exerted from a hydraulic source 21 to the oil chamber 15 via a piping 18 while the chambers 15 and 16 are isolated from each other by a spring means 27. The projecting part 14 is spaced from the wall part 13 by the sliding displacement of the piston 11 and the chambers 15 and 16 are communicated with each other when the overload acts on the device. On the other hand, the communication between the chambers 15 and 16 is interrupted by the spring means 27 in the resetting stage. The resetting of the overload releasing device to the normal state is thereby considerably speeded up.

Filed: 1980-10-29
Abstract: PURPOSE:To accurately detect a duration period or pause period of a reception signal, by increasing the discrimination level of a level discrimination circuit when the reception level of a reception is greater, and decreasing the discrimination level, when the reception level is small. CONSTITUTION:An output of an amplifying circuit 15 is divided at resistors 17, 18 and when the divided level exceeds a discrimination level l2 of a level discrimination circuit 19, an output of an integration capacitor 22 is at high level, and when less than the l2 level, the output of the capacitor 22 is at low level. An output is given to a transistor (TR)27 from the capacitor 22. On the other hand, the output of the circuit 15 is given to a level discrimination circuit 28 via a resistor 24. When the TR27 is conductive, the output of the circuit 15 is divided with the resistors 24, 25 only, and the divided output is lowered, and the discrimination level of the circuit 28 is increased. Further, the output of the circuit 28 is subject to envelop- detection with a detection circuit 29.

Title: Fast feeder of digital timer
Inventor: MAYUMI KAZUAKI
IPC: G04G5/00
Filed: 1977-12-19
Abstract: PURPOSE: To perform setting of the current time and setting of engaged time by supplying the signal which advances 1 count to an hour-minute counter through operation of a time setting key.  
     CONSTITUTION: When a key 9 is operated to U side or D side of the figure, the output of a frequency dividing circuit 4 is inhibited and a minute counter 6 is advanced by 1 count by the pulse at the differentiated leading edge, but a frequency dividing circuit 3 is reset by the same leading edge and therefore a flip-flop circuit 14 is not set until 1 second elapses. Because of this, no count pulse enters the counter 6 and therefore the counter (b) does not advance. When 1 second elapses, the counter 6 advances at each 1/20 second. In this way, the counter is fast fed up to the neighborhood of the minute value desired to be set and the operation of the key 9 is once stopped. When it is operated again, the counter 6 advances by only 1 count unless the key is kept pushed for more than 1 second and therefore the counter may be set easily at the required minute value.

Abstract: PURPOSE:To improve high frequency characteristic by composing an FET in the shape that a depletion layer is projected under a gate electrode. CONSTITUTION:With a semi-insulating substrate 7 as a base, a buffer layer 6 and an active layer 5 are formed, impurity ions are implanted to a region to become the source and drain of the layer 5 to form source and drain electrodes 1, 3.

Filed: 1998-06-02
Abstract: PROBLEM TO BE SOLVED: To attain the transition of the minimum resonance frequencies of a speaker to a low pass side, and to attain low pass enlargement and low pass radiation with satisfactory quality by using a cap fixed to a voice coil bobbin or a diaphragm as an oscillator for functioning an acting force in a reacting direction corresponding to the voice reflecting direction of the diaphragm. SOLUTION: An oscillator 26 which can be used also as a flexible cap 27 is connected with the top part of a voice coil bobbin 8 or the inclined part on the cone inner periphery of a diaphragm 7. The cross-section shape of the oscillator 26 is molded almost like recession, and a non-magnetic weight 30 is connected with the recessed part so that appropriate equivalent mass can be applied. The diaphragm 7 is driven to an arrow F1 direction according to an acoustic signal, and when a voice radiating force F1 works, a reacting force in an arrow -F1 is allowed to work on the diaphragm 7. Also, a reacting force -F2 is allowed to work on the oscillator 26 according to acceleration working on the weight 30.  Thus, the reacting force -F1 corresponding to the voice radiating force F1 of the diaphragm 7 and the reacting force -F2 working on the oscillator 26 can be made mutually offset or attenuated.
