Title: Belleville spring unit
Inventor: WATANABE YUKIO
IPC: F16F1/32
Filed: 1979-09-29
Abstract: PURPOSE:To make the axes of series-combined pural belleville springs hard to deviate, and attain a proper aligned state, by making the outside and inside diameters  of one of the plural facing belleville springs different from those of the other. CONSTITUTION:In application to the buffer mechanism of the control rod drive mechanism of a nuclear reactor, a plurality of belleville springs 2, 3,... are combined in series with each other and housed in an outer cylinder 1. An inner cylinder 4 is inserted into the belleville springs 2, 3,... so that the belleville springs are guided by the inner cylinder 4. An annular end plate 5 is secured on the tops of the outer cylinder 1 and the inner cylinder 4. A piston 6 is housed in the outer cylinder 1 in  contact with the lowest belleville spring 3. The outside diameter D1 and inside  diameter d1 of the belleville springs 2,... are made larger than those of the other belleville springs 3,... so that the peripheral edges of the belleville springs 3 are  located in contact with the insides of the peripheral portions of the other belleville  springs 2 and the inner circumferential edge of one belleville spring 2 is located in contact with the outside of the inner circumferential part of another belleville spring  3. These belleville springs are thus prevented from deviating.

Title: Signal waveform transmission system
Inventor: CHIYUUMA AKIRA
IPC: H04B3/04
Filed: 1977-10-21
Abstract: PURPOSE: To ensure the optimum reception for the signal featuring a large transmission distortion through switching of more than one unit of the equalizer.  
     CONSTITUTION: The signal sent from transmission circuit 1 receives distortion at transmission line 2 and then supplied to receiver circuit 5 via equalizer 4a. When some error is detected (6) in the signal at circuit 5, change-over swicth 3 is actuated by the detection output. And then the reception is carried out again by switching the equalizers. As each equalizer features different correcting performance, the optimum reception is possible though either one of the equalizers

Title: Optical pickup focus servo mechanism
Inventor: YOKOYAMA YOSHIHIKO
IPC: G11B7/085
Filed: 1991-05-29
Abstract: PURPOSE:To prevent the state that servo cannot be applied for a long time by changing a threshold to be compared in accordance with the intensity of a read signal to more accurately discriminate whether the relative speed is within a leading-in permission speed. CONSTITUTION:The output of a photo diode 8a is subjected to current-voltage conversion and is inputted to a subtracting circuit 14 and an adding circuit 15a. The output of the adding circuit 15a is a signal RF of the read signal of a disk, and this signal has the high frequency component eliminated through a low pass filter 18a to obtain a signal RF0. This signal RFO and the threshold corresponding to the intensity of the signal outputted from a peak holding circuit 24a are compared by a comparator 20a, and a switching signal is outputted from an AND gate 22a to perform switching from a sweep signal to a servo signal if the period when the signal RF0 is larger than the threshold is longer than the time constant determined by a monostable multivibrator 21a. Thus, the occurrence of discrimination error due to variance of the signal intensity is prevented.

Title: Automatic focus controlling mechanism of camera
Inventor: KOFUCHI KUNIOKI
IPC: G03B13/36
Filed: 1979-09-28
Abstract: PURPOSE: To make change-over of automatic focusing and manual focusing easy by transmitting the driving force of a cam for driving the taking lens by way of freely connectable and disconnectable relaying lever and taking lens drive lever.  
     CONSTITUTION: The driving force of a taking lens drive cam 10 is transmitted by way of a relaying lever 14 and a taking lens drive lever 16, whereby a taking lens 15 is moved on the optical axis. An electromagnetic member 19 is then energized by the focusing signal at the focusing corresponding to the distance measured with a movable mirror 2 and a coupling lever 18 is oscillated in the counterclockwise direction by way of a movable piece 20. This causes the levers 14, 16 to be disconnected, so that the driving force of the cam 10 is not transmitted to the lens 15 and automatic focusing is thus accomplished. On the other hand, this lever 18 responds to the manual operation of a change-over knob 22. Hence, if the levers 14, 16 are disconnected manually and the lever 16 is manually moved by the pin 22e of the knob 22, the focusing is easily changed over to manual focusing. As a result, even if no automatic focusing signal is generated, photographing is performed by manual focusing without losing shutter chance.

Abstract: PURPOSE: To realize an inexpensive paper feeder of simple constitution and to prevent malfunction by coupling a guide material for manual paper feed and an automatic paper feeding mechanism via a link mechanism and operating the function of only one of two.  
     CONSTITUTION: A guide plate 1 for manual paper feed is provided rotatably around a rotary shaft 4, and the setting table 16 of an automatic paper feeding mechanism is rotatable through a pushing-up material 13 rotating around a shaft 14; and both the shafts 4 and 14 are coupled togther via a link mechanism 21 composed of a transfer material 22, etc. For manual operation, drawing the guide plate 1 to this side pushes down the pushing-up material 13 through the mechanism 21, so automatic paper feed is disabled; and then transfer paper 11 is inserted into a paper feed opening 1a and manual copying is performed. When the guide plate 1 is stood upright, the setting table 16 is pushed up through the mechanism 21 to feed paper automatically. Thus, a simple, malfunction-free and inexpensive paper feeding mechanism is obtained.

Title: Combustion device
Inventor: TAKESHITA SHIRO
IPC: F23J13/00
Filed: 1991-05-29
Abstract: PURPOSE:To reduce noise generated during combustion in a combustion device. CONSTITUTION:An air discharging chamber 14 is composed of an inner chamber 16 and an outer chamber 17. The inner chamber 16 communicates with the outer chamber 17 through a discharging air blowing port 15 and the first communication port 18 disposed at an opposite side. The front side of the first communication port 18 of the outer chamber 17 is provided with a partition plate 19 for symmetrically partitioning the first communication port 18 and the outer chamber 17. Noise is once uniformly conducted to the back of the inner chamber 14 and from the first communication port 18, the noise is transmitted through the outer chamber 17, discharged from the discharging air blowing port 15 at the front surface of the device, resulting in that a transmitting passage extending up to a place where the noise is discharged into surrounding air can be elongated. Since many sound absorption members 21 disposed in the transmitting passage can be disposed, it is of course apparent that a reduction of noise can be attained and a sound of a standing wave frequency determined by a passage length of the outer chamber 17 enclosing the inner chamber 16 can be accommodated, so any frequency component can be reduced by setting the the passage length.
