Title: Rotation frequency sensor
Inventor: YOSHINAGA TOORU
IPC: H02P29/00
Filed: 1979-09-07
Abstract: PURPOSE: To reduce the electric power consumption by a method wherein power  supply is made intermittently to a magnetic sensor and the amplifier for amplifying  the output of the magnetic sensor in the noncontact rotation frequency sensor using a magnetic sensor.  
     CONSTITUTION: The change of a magnetic flux density due to the rotation of the rotary magnet 1 is converted to voltage through the magnetic sensor 2; and this voltage is amplified through the amplifier 3. The power supply to the above-mentioned magnetic sensor 2 and the amplifier 3 is controlled by the output of the pulse oscillator 8. Namely, when the pulse voltage obtained from the oscillator 8 is H, the transistor 9 is not continuous, thus, resulting in no voltage supply to the magnetic sensor 2 and the amplifier 3. On the other hand, when the pulse voltage obtained from the oscillator 8 is L, the transistor 9 is in continuation state, thus resulting in the voltage supplied to the magnetic sensor 2 and the amplifier 3. In this way, power supply is made to the magnetic sensor 2 and the amplifier 3 intermittently, which can reduce the consumption of power supply.

IPC: F16D3/32
Filed: 1986-05-19
Abstract: PURPOSE:To prevent damage to a universal joint by forming an intermediate joint approx. cylindrically, furnishing a stopper part to contact the end of said joint member round each joint shaft, and thereby hindering the acting angle of each joint shaft from becoming too large. CONSTITUTION:A high-angle, constant speed universal joint is composed of an intermediate joint member 10, a coupling 11, a pair of rings 12, 13, and a pair of joint shafts 14, 15. Said intermediate joint member 10 is formed approx. cylindrically as a whole, by coupling two approx. cylindrical halves 10a, 10b into a straight line. Tapered stopper parts 41, 42 in contact with the two ends of this joint member 10 are formed at the periphery of each joint shaft 14, 15 situated outside the joint member 10. If here the acting angle of each joint shaft 14, 15 varies, the coupling 11 moves along a groove 16 formed in said joint member 10 to put ball receivers 24, 25 in close contact with ball joints 39, 40. At this time, the stoppers 41, 42 work to prevent the acting angle from becoming excessive.

Title: Corona charger
Inventor: MATSUO YUZO
IPC: G03G15/02
Filed: 1990-05-07
Abstract: PURPOSE: To provide a corona electrifier capable of keeping an ozone decomposing effect over a long term by attaching an ozone decomposing plate including activated carbon, catalyst and binder material and processed to be activated to at least a part of a side opposed to the corona wire of a shielding case. CONSTITUTION: Ozone decomposing plates 5a to 5c are attached to the inner parts of the upper surface and the side parts of the shielding case 4. The plate 5 has porous structure principally constituted of the activated carbon, the catalyst and the binder, so that ozone gas produced by corona discharge is attracted to the porous surface area of the activated carbon and ozone is decomposed to oxigen molecules by the action of the catalyst existing on the surface area. Since many catalysis exist on the surface area of the activated carbon by using the plate 5 which is processed to be activated at a final stage, the excellent ozone decomposing action is kept over a long term.

Title: Fm receiver
Inventor: ISHIDA KOUJI
IPC: H04H40/45
Filed: 1979-09-10
Abstract: PURPOSE: To suppress generation of distortion to prevent degradation of the tone quality, by performing FM detection and seuarate demodulation of left and right channel signals simultaneously to shorten the path of the FM receiving signal as short as possible.  
     CONSTITUTION: The PPM (pulse position modulation) signal subjected to phase modulation is output from monostable multivibrator 7. The signal from subcarrier signal generating circuit 8 is applied not only to adder 9 as it is but also to another adder 11 through phase inverter 10 as the opposite-phase signal. Since DC components from DC bias generating circuit 16 are applied as addition inputs of adders 9 and 11, the normal and the opposite signals of the subcarrier signal are level-shifted by a prescribed DC level and are input to analogue gates 12 and 13 of the next stage. The PPM signal is used as the control signal for turning-on and off of gates 12 and 13, and respective gate outputs are input to integrating circuits 14 and 15.

And furthermore, a non-magnetic peeling member (scraper) 235, for example, formed of an elastic thin plate is stuck on a partition panel 234 fixed between a developer stirring member 232 and a developer supplying member 233 in a developing device 23, and the leading end part of the scraper is lightly press-contact with the cylindrical surface of a developing sleeve 231. Thus, a developer layer can be uniformly formed on the developer carrier 21.

The chip 12 is stopped in such a way that the contact point on the welding surface attains a welding temp. when the chip arrives at the prescribed position, then the material 1 is moved to start welding. When the distance from the rear end of the material 1 up to a squeeze roll 6 attains a specified value 16, the chip 12 is moved in the direction of a welding point 4 and the high frequency heating is continued under the adjustment of the high frequency current. The traveling of the pipe material 1 and the chip 1 is stopped when the chip approaches the rear end. The advance angle alpha is maintained constant during this time.

Filed: 1977-09-30
Abstract: PURPOSE: To provide a safe electric door apparatus which ensures automatic slow closure in case of power failure, by means of a drive motor having a field system formed by an armature and a permanent magnet and a means adapted to cause the armature to be shortcircuited through a resistance against a power failure.  
     CONSTITUTION: When the power supply (positive and negative) is fails, contactor coils C, O and H are deenergized. Consequently, any of contacts C 5 , O 5  and H 3  is closed and an armatuae A is short circuited through a resistance PR 2  in a circuit of A-H 3 -O 5 - C 5 -PR 2 -A. The resistance PR 2  is set at a lower level than that at deceleration, at deceleration, while the N and S arrangement of a permanent magnet provides a constant field system. A motor 6 generates a strong power generation torque.  The torque reduces to zero when the door is braked but it increases in proportion to  the speed of the door when it falls by the own weight. This ckecks the closing speed of the door from increasing beyond a given speed, ensuring a safe closure
